Orlando is making a design for a logo. He begins with a square measuring 22 inches on a side.
mestny [16]

Answer: A

Step-by-step explanation:

The first square is 22 inches on a side.

The second is 17.6 inches on a side

the third is 14.08 inches on a side.

We can suppose that we have a constant rate of decrease betwen the sides cubes, this means that:

22in*x = 17.6in

where x is the rate of scale.

x = 17.6/22 = 0.8

Now we test this with the second and third:

17.6in*0.8  = 14.08in

Ok, this works.

then the side of n-th cube can be found with the equation

L = 22*0.8^(n-1)

we can try the different options and see which one gives a value smaller than 10.

A) n = 5

L = 22*0.8^4 = 9.01

Then the correct option is A

Find cos B exactly if a = 15, b = 11, and angle Cis a right angle
astra-53 [7]

Answer:

Final answer is \cos\left(B\right)=\frac{15}{\sqrt{346}} which is the last choice.

Step-by-step explanation:

In triangle ABC, we have been given a = 15, b = 11, and angle C is a right angle.

Now using those values, we need to find the exact value of cos B.

Apply Pythagorean formula:

AB^2=AC^2+BC^2

AB^2=11^2+15^2

AB^2=121+225

AB^2=346

AB=\sqrt{346}

Now apply formula of cos

\cos\left(B\right)=\frac{BC}{AB}

\cos\left(B\right)=\frac{15}{\sqrt{346}}

Hence final answer is \cos\left(B\right)=\frac{15}{\sqrt{346}}
