vertex angle. How many degrees are in the vertex
angle?
The vertex angle of the isosceles triangle is 22°.
What is isosceles triangle?
A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.
We know that an isosceles triangle is composed of a vertex angle and two base angles. The base angles are congruent to each other. We also know that the sum of a triangle's angles is 180degrees.
Base angle = 3vertex angle+13.
=> 2base angle + vertex angle = 180°
=> 2(3 vertex angle +13)+vertex angle = 180°
=> 6 vertex angle+26+vertex angle = 180
=> 7 vertex angle = 180-26
=> 7 vertex angle = 154
=> vertex angle = 154/7 = 22°.
Hence the vertex angle of the isosceles triangle is 22°.

About 80 necklaces have more than 28 beads. Then the correct option is C.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and the standard deviation is 4 beads.
P(x > 28) = P(x - 24 / 4 > 28 - 24 / 4)
P(x > 28) = P(x - 24 / 4 > 1)
P(x > 28) = 1 - ∅1
P(x > 28) = 1 - 0.8413
P(x > 28) = 0.1587

Two investments totaling $64,500 produce an annual income of $3270. One investment yields 8% per year, while the other yields 2% per year. How much is invested at each rate?
Answer:
The amount invested at 8% is 64,500-32,000 = 32,500
Step-by-step explanation:
one investment: 3%, amount: x
the other: 8%, amount: 64,500-x because x is invested at 3%
0.03x+0.08(64,500-x) = 3,560
0.03x+5,160-0.08x = 3,560
-0.05x = -1,600 divide both sides by 0.05 and remember that -/- = +
x = 32,000 This is the amount invested at 3%
The amount invested at 8% is 64,500-32,000 = 32,500
Atmospheric pressure P
in pounds per square inch is represented by the formula P=14.7e−0.21x
, where x is the number of miles above sea level. To the nearest foot, how high is the peak of a mountain with an atmospheric pressure of 8.164 pounds per square inch? (Hint: there are 5,280
feet in a mile)
The mountain is ___ feet high?
The peak of the mountain has a height of 14805 feet.
How to determine the height of a mountain according to atmospheric pressure model
In this problem we find the case of an exponential function for atmospheric pressure (p), in pounds per square inch, in terms of height (x), in miles, whose expression is introduced below:
[tex]p(x) = 14.7 \cdot e^{- 0.21\cdot x}[/tex], for x ≥ 0.
If we know that p(x) = 8.164 lb / in², then the height of the peak of a mountain is:
[tex]8.164 = 14.7\cdot e^{-0.21 \cdot x}[/tex]
[tex]0.555 = e^{-0.21\cdot x}[/tex]
Then, by relationship between exponential and logarithmic functions and logarithm properties:
㏑ 0.555 = - 0.21 · x · ㏑ 1
㏑ 0.555 = - 0.21 · x
x = - (1 / 0.21) · ㏑ 0.555
x ≈ 2.804
Finally, convert miles into feet:
x = 2.804 mi × (5,280 ft / 1 mi)
x = 14805.12 ft

If f(x)=5x^6-2x^2-5, then what is the remainder when f(x) is divided by x+2?
Answer:
To find the remainder when f(x) is divided by (x-a) , we substitute x = a in the polynomial f(x) and we get the remainder.
remainder = f(a)
In this case, we have f(x)=5x^6-2x^2-5, and x+2 is the divisor and we substitute x=-2
so, remainder = f(-2) = 5*(-2)^6-2*(-2)^2-5 = -643
So, the remainder when f(x) is divided by x+2 is -643

= 4π/3( (r+3)[tex]^{3}[/tex] - [tex]r^{3}[/tex])
= 4π/3( [tex]r^{3}[/tex]+ 9[tex]r^{2}[/tex]+ 27r + 27 - r∧3 )
= 4π/3(9 [tex]3^{3}[/tex] + 27r + 27 )
= 12π( [tex]r^{2}[/tex]+ 3r + 3 ) in cube

An ice cream cone with a 2cm radius has a volume of 75.36 cubic cm how tall is the ice cream cone
Step-by-step explanation:
reading the question thoroughly, we find out that volume (V) and radius (r) of the cone is given, and we just have to find out the length (h) of the cone
V = πr²h/3
Putting the given values in place,
V = 75.36 cm³
V = 75.36 cm³r = 2 cm
V = 75.36 cm³r = 2 cmπ = 3.14
Now, since we calculating for h, we can interpret the formula in the terms of h, i.e.
h = 3V/(πr²)
h = 3×75.36/(3.14×2²)
h = 226.08/12.56
h = 18 cm
Thus, the height of the ice cream cone is 18cm

during the last 3 years consolidated oil company expanded its gasoline stations into convenience food stores (cfss) in an attempt to increase total sales revenue. the daily sales (in hundreds of dollars) from a random sample of 10 weekdays from one of its stores are:
One kind of average is the mean. It is calculated by dividing the total number of values in a list of values, such as measurements or numbers, by the total number of values in the list.
What is the mean in maths?There are various mean types in mathematics, particularly in statistics. Each mean helps to summarise a certain set of data, frequently to help determine the overall significance of a specific data set.The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.Only numerical variables—regardless of whether they are discrete or continuous—can be used to determine the mean. Simply dividing the total number of values in a data set by the sum of all of the values yields it.Given data :
a ) Mean =
x = [tex]\frac{\left \{ {{i=10} \atop {i=1}} \right.}{n} Xi[/tex] = 101 / 10 = 10.1 hundreds of dollars
The median is the 50th percentile To determine the location index for the median (2nd
quartile (p =50) we do the following:
The index is
i = [tex]\frac{p}{100}[/tex] (n) = [tex]\frac{50}{100}[/tex] (10) = 5 integer
Since the index, 5, is an integer, the 2nd quartile is determined by finding the average of
the 5th and 6th values from the lower or higher end of the sorted data. This is:
Median = [tex]Q_{2}[/tex] = [tex]\frac{10 + 11}{2}[/tex] = 10.5 hundreds of dollar
Mode = most frequently occurring observation = 11 hundreds of dollars ( two times )

Justin has a savings account.
• He started with $50 in his account.
• He deposits $12 into the account each week.
• Let b represent the amount Justin has in the bank after w weeks.
Which equation can be used to determine the total amount in Justin's account?
Answer: The equation that can be used to determine the total amount in Justin's account is:
b = 50 + (12 * w)
This equation represents the total amount in Justin's account, b, after w weeks. The equation starts with the initial amount, $50, which is the amount Justin had in his account before making any deposits. Then, it adds the amount deposited each week, $12, multiplied by the number of weeks, w. This results in the total amount in the account after w weeks.
In this equation the variable "w" represents the number of weeks that have passed and "b" represents the total balance.
Step-by-step explanation:
Use the given information to determine the number of elements in each of the four disjoint subsets in the following Venn diagram: n BAnBA' nB n(A) = 20 n(B) = 50, n(A nB) = 0, n(U) = 200 4' nB' (A) Find n(An B): n(An B) = (B) Find n(A n B'): n(Anb) = (C) Find n(A' n B): n(A' n B) =Ml (D) Find n(A' n B') n(A' 0 B') =
The value of the following venn expressions of sets is (A)=1 ,(B)=50,(C)=20 and (D)=130 respectively.
A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.
Symmetric difference between two sets A and B defined by,
AΔB=(A\B) ∪ (B\A)
AΔB=(A∩B') ∪(A'∩B).
we have n(A)=20 n(B)=50, n(A∩B)=0, n(U)=200
SO,
(A) Find n(A∩B)
n(A∩B) =0 (GIVEN)
(B) Find n(A∩B')
n(A∩B') =n(B)-n(A∩B)
= 50-0
=50
(C) Find n(A∩B')
n(A'∩B) =n(A)-n(A∩B)
=20-0
=20
(D) n(A'∩B') =n(U)-n(A'∩B)-n(A∩B)-n(A∩B')
=200-20-0-50
= 130.
thus, the above is the value of expression.

It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to find a function which solves the equation. Two classifications are the order of the equation -- (what is the highest number of derivatives involved) and whether or not the equation is linear .Linearity is important because the structure of the the family of solutions to a linear equation is fairly simple. Linear equations can usually be solved completely and explicitly. Determine whether or not each equation is linear:1. (1+y2)(d2y/dt2)+t(dy/dt)+y=et2. t2(d2y/dt2)+t(dy/dt)+2y=sin t3. (d3y/dt3)+t(dy/dt)+(cos2(t))y=t34. y''-y+y2=0You have 10 choices to choose for each problem:a. 1st. order linear differential equationb. 2nd. order linear differential equationc. 3rd. order linear differential equationd. 4th. order linear differential equatione. 5th. order linear differential equationf. 1st. order non-linear differential equation=g. 2nd. order non-linear differential equationh. 3rd. order non-linear differential equationi. 4th. order non-linear differential equationf. 5th. order non-linear differential equation
The coefficient of the second derivative (t2) is constant, so the equation is linear.
1. (1+y2)(d2y/dt2)+t(dy/dt)+y=et2 -> 2nd. order non-linear differential equation
2. t2(d2y/dt2)+t(dy/dt)+2y=sin t -> 2nd. order linear differential equation
3. (d3y/dt3)+t(dy/dt)+(cos2(t))y=t3 -> 3rd. order non-linear differential equation
4. y''-y+y2=0 -> 2nd. order non-linear differential equation
The order of a differential equation is the highest derivative involved in the equation. For example, in the equation 1 + y2(d2y/dt2) + t(dy/dt) + y = et2, the highest derivative is the second derivative (d2y/dt2), so this equation is of 2nd order. Linearity is determined by whether the coefficients of each derivative are constants, or whether they depend on the function y and its derivatives. In this equation, the coefficient of the second derivative (1+y2) is not constant, so the equation is non-linear. Similarly, in equation t2(d2y/dt2)+t(dy/dt)+2y=sin t, the coefficient of the second derivative (t2) is constant, so the equation is linear.
