Irina18 [472]

Answer:x = 9.01

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle the hypotenuse of the right angle triangle is 17

With 35 degrees as the reference angle,

x represents the adjacent side of the right angle triangle.

The unlabelled side represents the opposite side of the right angle triangle.

θ = 35 degrees

To determine x, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse side. Therefore,

Cos 35 = x/11

x = 11 Cos 35 = 11 × 0.8192

x = 9.01

Answer:

1.275

Explanation:

The given equation is:

f(x) = 0.01(2)ˣ

We want to find the rate of change from 2 to 10 which means that we need to find the slope from 2 to 10.

We start by getting the y-values for each of the given x-values:

at x = 2 ..........> y = 0.01(2)² = 0.04 ...........> point is (2, 0.04)

at x = 10 .........> y = 0.01(2)¹⁰ = 10.24 .........> point is (10, 10.24)

Now, we get the slope as follows:

slope =

Hope this helps :)
