Anton [14]2 years ago

7 0

Answer:

I'm not totally sure this is a VERY tricky question but I do know that 3 people did not say yes.

Step-by-step explanation:

Well if 70% of people said that they order toppings on pizza, then 30% don't order toppings. Therefore out of 10 people, 7 order toppings and 3 don't.

The water reaches a max height when the horizontal distance from the firefighter to the building is approximately __m. Round to

elena-s [515]

The horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m

<u>Explanation:</u>

Given:

h(x) = -0.026x² + 0.563x + 3

where,

h(x) is the height of the water

Initial speed, u = 14m/s

angle, θ = 30°

(a)

Horizontal distance = ?

h(x) = ax² + bx + c

the vertex is found at x = -b/2a

where,

x = distance to the maximum height

As compared to the equation given:

a = -0.026

b = 0.563

Thus,

$x = \frac{-0.563}{2 X -0.026} \\\\x = \frac{0.563}{0.052}\\ \\x = 10.83m$

Therefore, horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m

Figure f is a scaled copy of Figure e.

Mekhanik [1.2K]

The correct equation of the scaled figure is given by 6/3 = 4/a

<h3>Scaling</h3>

Scaling is the process of either increasing or decreasing the size of a figure by a factor.

From the diagram attached, Figure f is a scaled copy of Figure e. Figure e is decreased to produce figure f, hence:

AB/XY = CD / WZ
6/4 = 3 / a
6/3 = 4/a

The correct equation of the scaled figure is given by 6/3 = 4/a
