Answer: B

Step-by-step explanation:

(-3, -1) and (4, 5) are the points given

Slope formula: $\frac{Y2-Y1}{X2-X1}$

$\frac{5--1}{4--3} = \frac{5+1}{4+3} \\$

$\frac{5+1}{4+3} = \frac{6}{7}$

If f(x) = −5x − 4 and g(x) = -3x - 2, find (f+ g)(x).

Answer:

$(f+g)(x) = -8x-6$

Step-by-step explanation:

We are given the two functions:

$\displaystyle f(x) = -5x - 4 \text{ and } g(x) = -3x - 2$

And we want to find:

$(f+g)(x)$

Recall that this is equivalent to:

$\displaystyle (f+g)(x) = f(x) + g(x)$

Substitute and simplify:

$\displaystyle \begin{aligned} (f+g)(x) &= (-5x-4)+(-3x-2) \\ \\ &= -8x-6 \end{aligned}$

In conclusion:

$(f+g)(x) = -8x-6$

Find the area of a circle that has a diameter of 11 inches. Approximate Π as 3.14. Round your answer to the nearest hundredth.

Alexus [3.1K]

Answer: 94.99 in^2

Step-by-step explanation: The equation for the area of a circle is A=πr^2. To solve this, we need to find the radius. The diameter is the whole circle, whole the radius is half. So divide the diameter by 2.

11/2 = 5.5

The radius is 5.5 inches. Plug the radius into the equation.

A=π5.5^2

Square the 5.5 first. You will get 30.25.

A=π30.25

Plug in 3.14 for pi.

A=3.14 x 30.25

Multiply.

A=94.985

Round to the nearest hundredth.

A=94.99

The area of the circle is 94.99 in^2.
