a) The ratio of the perimeters is the same as the scale factor, so the ratio is the perimeters is 2/3.

b) The perimeter of triangle ABC is 36\left(\frac{3}{2} \right)=\boxed{54 \text{ ft}}

c) The ratio of the areas is the scale of the scale factor. In this case, the ratio is (2/3)^{2}=\boxed{4/9}

d) The area of FDE is 36(4/9)=\boxed{16 \text{ ft}^{2}}

Trig please help
dmitriy555 [2]

Answer:

One

Step-by-step explanation:

9/sin(34) = 6/sinC

sinC = 0.372795269

C = 21.9, 158.1

Since 158.1 + 34 = 192.1 > 180

Only one triangle can be formed with angle 21.9° at C

Suppose that the function u and w are defined as follows.
mars1129 [50]

That funky circle in the middle is the composition of the function. It asks you to take a function as an input and to yield an output that's another function. It's one of the five function operations, along with adding, subtracting, multiplying, and dividing.

When you compose, you might find the notation w(u(x)) easier to understand. It's saying evaluate u then evaluate w.

For our functions, the compositions are:

u(w(x)) = u(2x²) = -(2x²) - 2 = -2x² - 2

w(u(x)) = w(-x - 2) = 2(-x - 2)² = 2(x² + 4x + 4) = =2x²+ 8x +8

Now we evaluate each composition at 4.

u(w(4)) = -2(4²) - 2 = -2(16) - 2 = -32 -2 = -34

w(u(4)) = -2(2²) +8(2) + 8 = -2(4) + 16 + 8 = -8 + 16 + 8 = 16.

Thus, u(w(4)) = -34 and w(u(4)) = 16.

Jamie and Carrie are trying to determine what size ladder they are going to need to paint the house the. The house is 25ft tall
Oksanka [162]

Answer:

Step-by-step explanation:

By the Pythagorean Theorem we know that the hypotenuse squared is equal to the sum of its squared sides.

h^2=x^2+y^2

Here y=25 and x=8 so

h^2=25^2+8^2

h^2=625+64

h^2=689

h=26.25 ft

They obviously rounded to nearest whole foot.

So Carrie is correct in saying the ladder should be 26 feet.
