Answer:

p(1) = 6

Step-by-step explanation:

The basic idea is to put 1 wherever you see x. That gives you ...

p(1) = 2·1² +3·1 +1

The powers of x are all 1 when x=1, so the value of p(1) is just the sum of the coefficients:

p(1) = 2 + 3 + 1

p(1) = 6

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.

The quotient of 20 and 3 more than x is 4. Find x.

tigry1 [53]

Answer:

x=2

Step-by-step explanation:

Quotient means division

20/(x+3) =4

Multiply each side by (x+3)

(x+3)*20/(x+3) =4(x+3)

20 = 4(x+3)

Divide each side by 4

20/4 = 4(x+3)/4

5 = x+3

Subtract 3 from each side

5-3 = x+3-3

2 =x
