How is FG calculated?.
To calculate the composition of two functions, "F" and "G", represented by the notation "FG", you first need to have a specific input value, usually represented as "x".The first step is to apply the function "G" to the input "x", resulting in G(x).
The next step is to take the output of the function G, which is G(x), and use it as the input for the function F.
The final step is to apply the function F to the output of G(x) resulting in F(G(x)), which is the composition of the two functions F and G.
In other words, you apply the function G to the input x, and then you apply the function F to the result of G(x). The final result is the function F(G(x)), which is the composition of the functions F and G.
It's important to note that the order of the functions in composition matters and can change the result of composition. The notation "FG)(x)" is different from "GF)(x)" which means that the order of the functions matter in composition.

<RQT is a straight angle. What are m<RQS and m<TQS?
angle RQS = 101 degrees
angle TQS = 79 degrees
===================================================
Explanation:
A straight angle has a measure of 180 degrees. It's another way of saying "straight line".
The two angles shown add to 180.
We'll use this fact to solve for x.
(angleRQS) + (angleTQS) = angle RQT
(9x+2) + (7x+2) = 180
16x+4 = 180
16x = 180-4
16x = 176
x = 176/16
x = 11
Use this x value to determine the angles we're after.
angle RQS = 9x+2 = 9*11+2 = 99+2 = 101 degreesangle TQS = 7x+2 = 7*11+2 = 77+2 = 79 degreesCheck:
(angleRQS) + (angleTQS) = 101+79 = 180 which confirms the answer is correct.

You survey your class and 4 like vanilla ice cream
and 14 like chocolate ice cream. Write the ratio of
people who like vanilla to people who like chocolate ice
cream, then write the ratio in simplest form.
Answer: 2:7
Step-by-step explanation:
Vanilla icecream = 4
Chocolate icecream = 14
4:14=2:7
2X2=4
7X2=14
Step-by-step explanation:
a ratio is simply relating 2 (or more) groups and their sizes.
in our case here the ratio is
4/14 = 2/7
this is often written as
4:14 = 2:7
it means that for every 2 people liking (I assume "preferring") vanilla ice cream there are 7 people liking (preferring) chocolate ice cream.
FYI
in total, a ratio also tells us about the size of the sample for the observation or analysis. 4/14 tells us there are 18 (4+14) people in the survey. and the simplified form 2/7 tells us that we can split the whole survey group into units of 9 (2+7) people with the same behavior as the total group.
a ratio is a fraction (incl. all the calculation and comparison rules) with a special meaning.
so, don't mix the ratio up with e.g. the fractions of the different behaviors in the group :
4/18 = 2/9 of the whole group prefer vanilla.
14/18 = 7/9 of the whole group prefer chocolate.
the ratio is now the relative size relationship between both : 2/9 / 7/9 = 2/7
Is 52 a perfect square?.
No, the number 52 is not a perfect square. Because the square root of 52 is an irrational number.
An irrational number is a real number that cannot be expressed as a ratio of two integers, or in other words, as a fraction. Irrational numbers include numbers such as pi (π), the square root of 2, and the square root of 3, which are not terminating or repeating decimals. They cannot be written as a finite decimal or a fraction of integers. Irrational numbers have an infinite number of decimal places, which means they cannot be represented exactly as a decimal.
They are also non-repeating and non-terminating decimals. Irrational numbers have many important properties and applications in mathematics, such as in geometry, where they are used to calculate the lengths of curves and the areas of circles.

Find the Value of X in the Problem shown.
Answer:
X = 20
Step-by-step explanation:
The two quadrilaterals are similar to each other. So the ratio of each side of the larger quadrilateral to the corresponding side of the smaller quadrilateral must be the same.
Examining the two figures we see the side which has 68° and 128° pf the smaller quadrilateral has length 2
The corresponding side of the larger quadrilateral on the right is 6
So each side of the larger quadrilateral =6/2 = 3 times each side of the smaller one
Side which has length 10 pf the smaller quadrilateral corresponds to the side with length x+10 of the larger one. This ratio must also be 1:3
So

The heat Q required to raise the temperature of water varies jointly as the mass m of the water and the amount of temperature change T, and Q = 20,930 joules(J) when m = 1kg and T = 5° C. To the nearest tenth of a kilogram, find m when Q = 8,349 J and T = 3°C. When Q = 8,349 J and T = 3°C, the mass of the water m is _ kg
To the nearest tenth of a kilogram, m = 0.6 kg.
What is ttemperature rate ?
With increase in temperature, the rate of the reaction and the rate constant increases. As a generalization, the rate of the reaction (and the rate constant) becomes almost double for every ten degree rise in temperature. This is also called temperature coefficient.
the heat Q required to raise the temperature of water varies jointly as the mass m of the water and the amount of temperature change T, and Q = 20,930 J when m = 1 kg and T = 5°C.
So, write an equation for Q as:
Q = k * m * T
where k is a constant of proportionality.
Substituting the known values, we can find k:
20930 = k * 1 * 5
k = 20930 / (1 * 5) = 4186
Now that we have k, use it to find m when Q = 8349 J and T = 3°C:
8349 = 4186 * m * 3
m = 8349 / (4186 * 3)

k = Q / (m * T) = 20,930 / (1 * 5) = 4186
Now that we have found k, we can use it to find m when Q = 8,349 J and T = 3°C:
Q = k * m * T
8,349 = 4186 * m * 3
m = 8,349 / (4186 * 3) = 8,349 / 12,558

Answer:
x = 7 , VS = 6
Step-by-step explanation:
• If two chords of a circle are equidistant from the centre of the circle then they are congruent.
given ZU and ZV = 5
then the chords QR and ST are equidistant from the centre and are congruent , that is
QR = ST
2x - 2 = 12 ( add 2 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
---------------------------------------------------
• If a radius is perpendicular to a chord then it bisects it.
radius ZY is perpendicular to chord ST and bisects it, so
VS = [tex]\frac{1}{2}[/tex] × ST = [tex]\frac{1}{2}[/tex] × 12 = 6

The number of atoms that can be laid end-to-end on a meter stick is equivalent to 10^8 atoms.
A meter is equivalent to 100 centimeters (cm), and an atom is about 10^-8 centimeters in length. So, when we divide the length of a meter stick (100 cm) by the length of one atom (10^-8 cm).
we are essentially dividing 100 by a decimal number on the order of 0.00000001.
This is the same as multiplying 100 by a number on the order of 100,000,000. In other words, we are multiplying 100 by 10^8.
So, 100 cm / (1*10^-8 cm) = 10^8 atoms

The tallest lighthouse in the world is the Jeddah Light. It is 133 m tall. A dhow is sailing away from this lighthouse. From the top of the lighthouse, the angle of depression to the dhow is 65° Later, the angle of depression has changed to 40°.
How far did the dhow travel during that time?
The tallest lighthouse in the world is the Jeddah Light. It is 133 m tall. A dhow is sailing away from this lighthouse. From the top of the lighthouse, the angle of depression to the dhow is 65° Later, the angle of depression has changed to 40°.
How far did the dhow travel during that time?
To solve this problem, we can use trigonometry and the fact that the angles in a triangle add up to 180°.
Let's call the distance between the lighthouse and the dhow "d".
We know that the angle of depression from the top of the lighthouse to the dhow is 65°, and the angle of depression later changed to 40°.
Let's call the angle between the horizontal and the line of sight from the lighthouse to the dhow, "x"
Since the angles in a triangle add up to 180°, we can say that:
x + 65 + 40 = 180
x = 75
Now, we can use the tangent function to find the distance d. We know that:
tan(x) = d / h
tan(75) = d / 133
d = 133 * tan(75)
Therefore, the dhow traveled 133 * tan(75) distance during that time.
Part A: Write the polynomial function with zero { -2, 0, 3√2 }
Part B: Write the polynomial function with zero { -1, 3, 2i }
The polynomial function with zeroes at -2, 0, and 3√2 is (x+2)(x-0)(x-3√2) = [tex](x+2)*(x-3\sqrt{2}) = x^3 - 3x\sqrt{2x} - 2x^2.[/tex]
The polynomial function with zeroes at -1, 3, and 2i is (x+1)(x-3)(x-2i) = [tex](x+1)(x-3)(x^2+4) = x^3 +x^2 - 11x -12[/tex]
A polynomial function is a function of the form f(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0, where n is the degree of the polynomial and the a_i are constants. To find a polynomial function with zeroes at -2, 0, and 3√2, we can use the fact that if a polynomial function has a zero at x=c, then (x-c) is a factor of the polynomial. Therefore, we can write the polynomial function as [tex](x+2)(x-0)(x-3\sqrt{2}) = (x+2)x(x-3√2) = x^3 - 3x\sqrt{2x} - 2x^2[/tex].
In this case, we can see that x = -2, x = 0, x = 3√2 are the zeroes, so we know that (x+2), x and (x-3√2) are the factors of the polynomial.
Similarly, to find a polynomial function with zeroes at -1, 3, and 2i, we can use the fact that if a polynomial function has a zero at x=c, then (x-c) is a factor of the polynomial. Therefore, we can write the polynomial function as [tex](x+1)(x-3)(x-2i) = (x+1)(x-3)(x^2+4) = x^3 +x^2 - 11x -12[/tex]
In this case, we can see that x = -1, x = 3, x = 2i are the zeroes, so we know that [tex](x+1), (x-3), (x^2+4)[/tex]are the factors of the polynomial.
It is worth noting that (x-2i) is a zero of the polynomial, so (x-2i)(x+2i) = [tex]x^2[/tex]+4 is a factor of the polynomial and it is included in the polynomial..

What is the axis of symmetry of the quadratic function y x 3 ² 2?.
The axis of symmetry is the line x=3.
As y is a linear term and x is quadratic, this means we’re dealing with either an ‘n-shaped’ parabola or a ‘u-shaped’ parabola.
As the coefficients of x² and y have the same sign they’re both positive, which means we have a ‘u-shaped’ parabola.
One can express a parabola in the vertex form, y=a(x−p)²+q, which tells us that the vertex is the point (p,q) and the axis of symmetry is the line x=p.
So, let’s apply this format to your parabola.

The formula to determine the period of one
swing of a simple pendulum is
L
T = 2√, where L is the length of the
string and g is the acceleration due to
gravity. Solve the formula to solve for g in
terms of T, T and L.
Answer:
To solve for g in terms of T, L, we can manipulate the formula T = 2π √(L/g) as follows:
First, we divide both sides by 2π:
T/2π = √(L/g)
Then, we square both sides:
(T/2π)² = (L/g)
Then, we multiply both sides by g^2 :
(T^2/4π^2) = L
Finally, we divide both sides by L:
(T^2/4π^2 * L) = g
So the formula for g in terms of T, L is g = (T^2/4π^2 * L)
Please note that this formula is only valid for simple pendulum and not for any complex pendulum, and also the result is in terms of acceleration due to gravity g.
