Answer:

Step-by-step explanation:

domain represents the numbers at the x endpoints of a graph.

on the graph we see that on the left, the line ends when x is -4

on the right, the line ends when x is 4

the domain is

-4, 4

but notice how on the left there is an open circle

this will be written with a parentheses

( -4, 4

and notice how on the right there is a closed circle

this will be written with a bracket

(-4, 4]

so the answer is C

Answer:

31.42 m

Step-by-step explanation:

10* π= 31.415( which can round to 31.42)

Step-by-step explanation:

Diameter= 10 m

Circumference of a circle= π×Diameter

= π×10

= 31.41593 or 31.42

Answer:

-52, -69, -89, -100, -124

Step-by-step explanation:

Answer:

-124,-100,-89,-62,-52

Step-by-step explanation:

If the number is a high number and it's a negative it is the least. For example, if you have $-100 in your bank account, that's worse than having $-52. I hope this helps.

Answer:

C

Step-by-step explanation:

A coefficient of 4 would have to be added in front of (x+1)^2 in order to vertically stretch the function by a factor of 4.

The answer that demonstrates this is choice C: [tex]f(x) = 4(x+1)^2-1[/tex]

The functions stretches vertically by a factor of 4 will be f(x) = 4(x+ 1)² - 1. Then the correct option is C.

Let the point (h, k) is the vertex of the parabola and a is the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The quadratic function is given below.

f(x) = a(x+ 1)² - 1

If the value of the leading coefficient lies between 0 to 1. Then the parabola is stretched horizontally.

And if the value of the leading coefficient is greater than one. Then the parabola is stretched vertically.

The functions stretches vertically by a factor of 4. Then the value of the leading coefficient is 4. Then the equation will be

f(x) = 4(x+ 1)² - 1

Then the correct option is C.

1+2(3)=7

7 isn't equal to 5 so 1,3 is NOT a solution for this system of equations

Answer:

C. 70 in sq

Step-by-step explanation:

The formula of a trapezoid is the A = a + b / 2 multiplied by height. (a and b are the bases). If you plug in the numbers into the formula, you will get 70.

The functions that are symmetric about the y-axis are;

1) The function in the first option; f(θ) = cos(θ)

2) The function in the third option; f(x) = x²

Reason for the above selection;

Definition;

A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x

Analysis of the graphs;

First Function Graph; The graph represents the graph of cos (θ)

∴ The function is f(θ) = cos(θ)

The value of the function when x = π, f(π) = -1

Similarly, the value of the when x = -π, f(-π) = -1

f(π) = f(-π)

∴ f(x) = f(-x)

Therefore; the first function is an even function

Second Function Graph; The function of the graph is x = y²

∴ y = √(x)

The value of the function when x = 4, y = f(4) = 2

However, the when x = -4, f(-4) does not exist

f(4) ≠ f(-4)

∴ f(x) ≠ f(-x)

Therefore; the second function is not an even function (the function, x = y², is however symmetric about the x-axis)

Third Function Graph; The function the graph represents is y = x²

The value of the function when x = 2, f(2) = 4

Similarly, the value of the when x = -2, f(-2) = 4

f(2) = f(-2)

∴ f(x) = f(-x)

Therefore; the third function is an even function

From the above, the functions which are symmetric about the y-axis, (even functions) are;

The first and the third functions

B) 0.57

Step-by-step explanation:

It says "given that you are in Sacramento", so hint: only look at the Sacramento row. Ignore everything else, you don't need it.

Then it asks what is the probability of a clear day, so you look at the "Clear" column from the Sacramento row. That would be 17 days.

Lastly, you just simply divide from the total days. 17/30 = 0.57
