Answer:

Neither

Step-by-step explanation:

<u>Given sequence:</u>

3, 5, 9, 17, ...

<u>We can write the terms as:</u>

3 = 2^1 + 1
5 = 2^2 + 1
9 = 2^3 + 1
17 = 2^4 + 1
...
aₙ = 2^n + 1

As we see the sequence doesn't meet AP or GP criteria, there is no common difference or common factor between the terms

Answer:

Step-by-step explanation:

f(x) = 5^(x+1 )– 1

f(0)= 5^(0+1 )– 1 = 5^(1 )– 1 = 5-1=4

A right triangle contains a 38° angle whose adjacent side measures 10 centimeters. What is the length of the hypotenuse, to the

True [87]

Answer:

12.69 inches.

Step-by-step explanation:

Let h represent the length of the hypotenuse.

We have been given that a right triangle contains a 38° angle whose adjacent side measures 10 centimeters. We are asked to find the length of the hypotenuse.

We know that cosine relates adjacent side to hypotenuse of right triangle.

$\text{cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}$

$\text{cos}(38^{\circ})=\frac{10}{h}$

$h=\frac{10}{\text{cos}(38^{\circ})}$

$h=\frac{10}{0.788010753607}$

$h=12.690182$

Upon rounding to the nearest hundredth of a centimeter, we will get:

$h\approx 12.69$

Therefore, the length of the hypotenuse is approximately 12.69 inches.
