Complete the table of inputs and outputs for the given function. F(x)= -5(x+7)
levacccp [35]

The table of inputs that satisfy the given function is (<em>-2, 25), (-1, -30), (0, 35), (1, -40) and (2, -45).</em>

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the function f(x) = -5(x + 7)

When x = -2; f(-2) = -5(-2 + 7) = -25

When x = -1; f(-1) = -5(-1 + 7) = -30

When x = 0; f(0) = -5(0 + 7) = -35

When x = 1; f(1) = -5(1 + 7) = -40

When x = 2; f(2) = -5(2 + 7) = -45

The table of inputs that satisfy the given function is (<em>-2, 25), (-1, -30), (0, 35), (1, -40) and (2, -45).</em>

s below which does not belong? motivation self confidence positive attitude coordination conscientiousness
Alenkinab [10]
I would say that coordination doesn't belong. The other words seem to do with a person's personality or mentality, while coordination is more of a physical ability.

It is 26cm.

Step-by-step explanation:

Do  Pythagorean theorem, a^2+b^2=c^2

So 24^2+10^2,

576+100,

676.

Next, we square root it to simplify c^2 to get c by itself

(sqrt)676,

26.

The function f is defined by f(x)=2x^2-4.<br> Find f(-x)
Vedmedyk [2.9K]
First of all, since all powers of x in this function are even, the entire function is even.  Thus, using -x as input doesn't change the function.  Thus, f(-x)=2x^2-4.

A circular region has a population of about 260000 people and a population density of about 135 people per square mine . find th
ValentinkaMS [17]

Answer:

24.76 mine

Step-by-step explanation:

The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:

260000/135 = 1925.93

The area would be 1925.93 square mine

We know that the area is given by:

A = pi * r ^ 2

we solve to r

r ^ 2 = A / pi

r ^ 2 = 1925.92 / 3.14

r ^ 2 = 613.3

r = 24.76

the radius is equal to 24.76 mine
