Answer:

10/10

Step-by-step explanation:

you take every number to 10 like half is 5/10. the 8 year olds are 2/10. so 5+1+2+2 = 10/10 so the buss is full.

Answer:

28

Step-by-step explanation:

Because 14 times 2 is 28, and 28 divided by 2 is 14.

The image of  y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:

The graph will be a vertical parabola opening downwards

when the function y = −2x^2 − 20x + 2 translates right 4 units it gives  

y = -2(x - 4)^2 − 20(x - 4) + 2

going up two units

y = -2(x - 4)^2 − 20(x - 4) + 2 + 2

simplifying the equation further gives

y = -2(x - 4)(x - 4) − 20(x - 4) + 4

y = -2(x^2 - 8x + 16) - 20x - 80 + 4

y = -2x^2 + 16x - 20x - 32 - 80 + 4

y = -2x^2 - 4x - 108

completing the square

-2x^2 - 4x - 108 = 0

-2x^2 - 4x = 108

-2x^2 - 4x + (4/4)^2 = 108 -(4/4)^2

-2x^2 - 4x + (1)^2 = 108 - 1

-2(x + 1)^2 - 107

The required value of function f(g(2)) = 1.

What is a composite function?

When the result of one function is utilized as the input for another, this is known as a composite function.

Typically, a composite function is a function that is embedded within another function. The process of creating a function involves replacing one function for another.

Given, to find the value of the given function f(g(2))

First, we need to find the value of g(2) from the given graph

i.e. g(2) = 4  (i.e. x = 2)

Then, the above value is an input for function f.

So, f(4) = 1 (from the graph at x = 4)

Hence, the value of function f(g(2)) = 1.

The measure of angle H is 44°. in the parallelogram.

What is parallelogram?

A unique variety of quadrilateral made up of parallel lines is known as a parallelogram. A parallelogram can have any angle between its adjacent sides as long as its opposite sides are parallel. If two opposite sides of a quadrilateral are parallel and congruent, it will be a parallelogram. Consequently, a quadrilateral in which both pairs of opposite sides are parallel and equal is known as a parallelogram.

We can solve this easily using alternative interior angles. A parallelogram's interior is always 360 degrees, right?

(4x + 16)° + (2x - 16)° = 180

6x = 180

x = 180/6 = 30

So the angle H = 2*30 - 16 = 44°

To visualize the parallelogram, drawing it out is always helpful. Greg S., a widely renowned mathematician who specializes in geometry, says the answer is 44 degrees.

Hence The measure of angle H is 44°.

The value of cos x°  is 8 divided by f

We will use trigonometrical ratios to solve this problem. Below are the definitions of the trigonometrical ratios:

sin = opposite/hypotenuse

cos = adjacent/hypotenuse

tan = opposite/adjacent or tan = sin/cos

The opposite is the side the angle of consideration is facing

The hypotenuse is the side the right angle  is facing

The adjacent is the side left after determining the opposite and hypotenuse

Given: tan x° = e/8 and sin x° = e/f

Since tan = opposite/adjacent, that means in tan x° = e/8, opposite = e and adjacent = 8. Also, sin = opposite/hypotenuse, so in sin x°= e/f, hypotenuse = f

And cos = adjacent/hypotenuse. Thus,  cos x° = 8/f.

Therefore, the value is cos x° = 8 divided by f is the answer. Pick the first option
