Caitlyn needs to mail a USB drive to a friend. She uses 42 -cent stamps and 5 -cent stamps to pay $1.71 in postage. How many of each stamp did Caitlyn use?
Solving an equation we will see that Caitlyn used 3 of the 42-cent stamps and 9 of the 5-cent ones.
How many of each stamp does she use?Let's define the variables that we will be using:
x = number of 42-cent stapms.y = number of 5-cent stamps.Then the total value of the stamps, in dollars, is:
x*0.42 + y*0.5
And we know that the value must be $1.71, then we can write the equation:
x*0.42 + y*0.05 = 1.71
y = (1.71 - x*0.42)/0.05
To find the values of x and y, we can just evaluate in different whole values of x, until we get a whole value of y.
using x = 1 we get:
y = (1.71 - 0.42)/0.05 = 2.58
This is not a solution.
if x = 3
y = (1.71 - 0.42*3)/0.05 = 9
This is the solution, she used 3 of the 42-cent and 9 of the 5-cent.

Evaluate the integral below by interpreting it in terms of areas. In other words, draw a picture of the region the integral represents, and find the area using geometry.-5 ∫5 sqrt(5^2−x^2) dx my lower limit is -5 and my upper is 5. How do I solve this problem? do i graph this equation and use left or right approximation?
Answer:
[tex]\frac{25\pi}{2}\approx39.27\text{ units}^2[/tex]
Step-by-step explanation:
I assume your problem is [tex]\displaystyle \int\limits^{5}_{-5} {\sqrt{5^2-x^2}} \, dx[/tex]. Recognize that [tex]\sqrt{5^2-x^2}=\sqrt{25-x^2}[/tex] is a semi-circle directly above the x-axis with a radius of 5. The bounds cover the whole area of the semicircle, so its area is just half the area of a circle with a radius of 5. You probably know that the area of a circle is [tex]A=\pi r^2[/tex], so the area of a semicircle would be [tex]A=\frac{\pi r^2}{2}[/tex]. Thus, the area using geometry is [tex]A=\frac{\pi (5)^2}{2}=\frac{25\pi}{2}\approx39.27\text{ units}^2[/tex].
The acceleration function (in m/s2) and the initial velocity are given for a particle moving along a line.

The distance traveled during the given time interval be 2024 m.
What is meant by acceleration function?An object's rate of change in velocity is referred to as its acceleration. The rate of change in velocity is known as acceleration. Acceleration typically signals a change in speed, though this is not always the case. Because of the shifting direction of its velocity, an item moving on a circular path at a constant speed is still accelerating.
By integrating the velocity v in terms of time t, v = gt, we can determine acceleration, which is the rate of change of velocity with respect to time.
Let the function be a(t) = t + 4
time = 11
substitute the value of t in the above equation, we get
a(11) = 11 + 6 = 17 m/s²
a = v/t, so v = at
finally v = (17 m/s²) (11s)
v = 187 m/s
b) Find the distance traveled during the given time interval
[tex]$$V_{total} = V_{final} - V_{ initial[/tex]
V final = 187 m/s, Vinitial = 3 m/s
V total = 187 - 3 = 184 m/s
Let the equation of velocity be
Velocity = distance/time
distance = velocity × time
distance = 184 m/s × 11 s
distance = 2024 m
Therefore, the distance traveled during the given time interval be 2024 m.

The correct answer is open angled bracket negative 16 over 5 comma negative 32 over 5 close angled bracket, as it is the vector u.
The projection of vector u onto vector v is given by the formula:
projv(u) = (u . v/||v||^2) * v
where u . v is the dot product of vectors u and v,and ||v|| is the magnitude of vector v
Given that u = <-10, -3> and v = <4, 8>, we can substitute these values into the formula and find projv(u)
projv(u) = ( (-10)(4) + (-3)(8) )/ (4^2 + 8^2) * <4,8>
projv(u) = ((-40 - 24)/ (16 + 64))* <4,8>
projv(u) = (-64/80) * <4,8>
projv(u) = (-4/5) * <4,8>
projv(u) = <-16/5,-32/5>
The vector u is already parallel to the vector v, that's why the projection of vector u on vector v is equal to vector u itself.

How do you find a arc length without a radius? Need a answer asap.
the length of the arc will be C/2π*Ф.
What is circle?
The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.
The radius of a circle and its centre angle both affect how long an arc is. We are aware that the arc length and circumference are equivalent at an angle of 360 degrees (2). Due to the continuous relationship between angle and arc length, we can therefore state that:
L/Ф = C/2π
L = C/2π*Ф
Hence the length of the arc will be C/2π*Ф.

The pre-image, quadrilateral ABCD was dilated to produce the image, quadrilateral A'B'C'D'. The length of the side between the vertices A and B is 5 inches. What is the length of the side between the vertices A' and B', when vertices B'C' is 9 inches and vertices BC is 12 inches?
The length of the side between the vertices A' and B' is 3.75 inches
How to find the length of the side between the vertices A' and B'?In order to find the length of the side between the vertices A' and B', we need to use the fact that the ratio of corresponding side lengths between the pre-image and the image is the same as the ratio of the scale factor used in the dilation.
The ratio of the side length between the vertices B'C' and BC is 9/12. If we call this ratio k, then the ratio of the side length between the vertices A'B' and AB is also k.
So we can use the side length between AB = 5 inches and k = 9/12 to find the side length between A'B'
A'B' /AB = k
A'B' = k × AB
A'B' = (9/12) × 5
A'B' = 3.75 inches

Airline passengers get heavier In response to the increasing weight of airline passengers, the Federal Aviation Administration (FAA) in 2003 told airlines to assume that passengers average 190 pounds in the summer, including clothes and carry-on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 30 passengers.
• (a) Explain why you cannot calculate the probability that a randomly selected passenger weighs more than 200 pounds.
• (b) Find the probability that the total weight of the passengers on a full flight exceeds 6000 pounds. Show your work. (Hint: To apply the central limit theorem, restate the problem in terms of the mean weight.)
The probability that the total weight of the passengers on a full flight exceeds 6000 pounds is about 0.0147 or 1.47%.
What is the Central Limit Theorem?
The Central Limit Theorem states that the sum of a large number of independent and identically distributed random variables is approximately Normally distributed.
(a) The reason why you cannot calculate the probability that a randomly selected passenger weighs more than 200 pounds is that the weight of passengers is not Normally distributed.
The Normal distribution is a symmetric bell-shaped distribution that is defined by its mean and standard deviation.
The weight of passengers is not symmetric and it may not follow a bell shape.
Therefore, we cannot use the Normal distribution to calculate the probability of a weight greater than 200 pounds.
(b) To calculate the probability that the total weight of the passengers on a full flight exceeds 6000 pounds, we can use the Central Limit Theorem.
Since we don't know the exact distribution of the weight of the passengers, we can use the Central Limit Theorem to approximate the total weight of the passengers on a full flight.
The mean weight of a passenger is 190 pounds, and the standard deviation is 35 pounds. Since a full flight carries 30 passengers, the mean weight of the passengers on a full flight is 19030 = 5700 pounds and the standard deviation is 35sqrt(30) = 175 pounds.
To find the probability that the total weight of the passengers on a full flight exceeds 6000 pounds, we can use the standard normal distribution table.
z = (6000 - 5700) / 175 = 2.2857
Probability P(X > 6000) = P(Z > 2.2857) = 1 - P(Z < 2.2857) = 1 - 0.9853 = 0.0147
Hence, the probability that the total weight of the passengers on a full flight exceeds 6000 pounds is about 0.0147 or 1.47%.

What is meant by parallel line?In a plane, lines that are consistently spaced apart from one another are referred to as parallel. Parallel lines don't ever intersect. Perpendicular lines are those that intersect at a 90-degree angle.Parallel lines are two lines that are never crossed and are equally spaced apart from one another.They could be horizontal or vertical. Parallel lines can be found in our daily life in the form of nearby train tracks, rows of notebooks, and zebra crossings.Since there is no "b" in the conventional equation y = mx + b, the line y = 4x has a slope of 4 and an intercept of 0. Any parallel line will have the same slope as the slope (m = 4) in this case. The slope of all parallel lines will be the same.
So let's return to the conventional format and replace the m with a "4".
y = 4x + b
Now that the values have been entered into the equation, let's solve for "b" using the point that sits on the line.

A vector (u) with magnitude 4 in the opposite direction as v =⟨−2,3⟩ is u = ⟨-2/√13, 3/√13⟩.
A vector in the opposite direction of a given vector can be found by multiplying that vector by -1. The magnitude of a vector is the length of the vector and it can be found by using the Pythagorean theorem on the coordinates of the vector.
The magnitude of the vector v = ⟨-2,3⟩ is:
|v| = √(-2)^2 + 3^2 = √4 + 9 = √13
To find a vector with magnitude 4 in the opposite direction as v, we can first normalize the vector v by dividing it by its magnitude,
then multiply it by 4:
u = (-1) * (1/|v|) * v
= (-1) * (1/√13) * ⟨-2,3⟩
= ⟨2/√13, -3/√13⟩

A trapezium ABCD is inscribed into a semi-circle of radius l so that the base AD of the trapezium is diameter and the vertices B and C lie on the circumference. Then the value of base angle θ (in degree) of the trapezium ABCD which has the greatest perimeter, is
The value of base angle θ (in degree) of the trapezium ABCD which has the greatest perimeter, is 60°
Given, AD = 2I
From ΔABD,
cos∅=[tex]\frac{AB}{AD}[/tex]
⇒ AB = AD cos∅
⇒ AB = 2I cos∅
and x = ABcos∅ = 2I [tex]cos^{2}[/tex]∅
Now perimeter,
P = 2I+ 2I - 2x + 2AB
P = 4I - 4I [tex]cos^{2}[/tex]∅ + 4Icos∅
P = 4I (1 - cos²∅ + cos∅)
Differentiating with respect to ∅, we get
dP/d∅= 4I(2 cos∅ sin∅ - sin∅)
For max/min,
dP/d∅ = O
2 cos∅ sin∅ - sin∅ = 0
⇒ cos∅ = [tex]\frac{1}{2}[/tex] (∅ [tex]\neq[/tex] 0)
= 60°
[tex]d^{2}[/tex]P/d∅ = 4i(2 cos2∅ - cos∅)
[tex]d^{2}[/tex]P/d∅ < 0
∅ = 60°
Therefore, Perimeter is maximum when ∅ = 60°

Examine the number line,and then choose the correct symbol to complete each statement
After examine the number line,and then the correct symbol to complete each statement is -2/4<-1/4; 3/4>2/4;-1/4<0.
What is Number line ?
A number line is a diagram of a graduated straight line used to represent real numbers in introductory mathematics. It is assumed that every point on a number line corresponds to a real number, and that every real number corresponds to a point.
What is Symbol?
A mark, sign, or term that denotes, denotes, or is taken to denote an idea, an item, or a relationship is known as a symbol. By connecting seemingly unrelated ideas and events, symbols help people look beyond the known and the visible.
In the question given some relation between the real number which are
a) -2/4 < -1/4 because negative number has the property that the those numbers which is smaller is always greater.
b) 3/4 > 2/4 both numbers are positive so clearly it 3/4 comes after 2/4 so it is greater.
c) -1/4 < 0 zero is always greater than the negative numbers
So, after examine the number line,and then the correct symbol to complete each statement is -2/4<-1/4; 3/4>2/4;-1/4<0.
