P=2L+2W
L=Length
W=Width
P=Perimeter=16
So you have:
16=2×5+2w
Multiply 2 and 5 and get:
16=10+2w
Subtract 10 from both sides and get:
6=2w
Divide by 2 and get:
3=W
The width is 3.

Which statements about the graph of the function f(x) = –x2 – 4x + 2 are true? Check all that apply.
Nitella [24]

Answer:

See attached picture

Step-by-step explanation:

The function f(x) = -x^2-4x+2 has the following characteristics:

• Not factorable

• Zeros/roots: x= -2 +/- \sqrt {6}

• Negative leading coefficient

•       Has a vertex at (-2,6)

• Its graph is a parabola and upside down U shape.

• It has a maximum value of 6.

Who oh of the following illustrates the truth value of the given statements? January is the first month of the year or December
IrinaK [193]

Answer: T T > T

Step-by-step explanation:

Step 1: Determine if the statements are true or false.

1) January is the first month of the year---statement is true

2) December is the last month of the year---statement is true

With this, the truth value will be:

T T > T

The two statements are true, therefore, conjunction of both statements will also be true.

I hope this helps.

The graph of f(x) = StartRoot x EndRoot is reflected across the x-axis and then across the y-axis to create the graph of functio
allsm [11]

Answer:

The true statements:

The only value that is in the domains of both functions is 0.

The range of g(x) is all values less than or equal to 0.

==================================

Step-by-step explanation:

See the attached figure:

As shown: f(x) = √x with blue color

When f(x) is reflected across the x-axis the result will be (-√x) with red color.

Then the is reflected result across the y-axis to create the graph of function g(x) = -√(-x) with green color.

<u>Domain </u>of f(x) = [0,∞) & <u>Range</u> of f(x) = [0,∞)

<u>Domain </u>of g(x) = (-∞,0] & <u>Range </u>of g(x) = (-∞,0]

So, according to previous, we will check the statements:

1) The functions have the same range. <u>(Wrong)</u>

2) The functions have the same domains. <u>(Wrong)</u>

3) The only value that is in the domains of both functions is 0. <u>(True)</u>

4) There are no values that are in the ranges of both functions. <u>(Wrong)</u>

5) The domain of g(x) is all values greater than or equal to 0. <u>(Wrong)</u>

6) The range of g(x) is all values less than or equal to 0. <u>(True)</u>

One of the factors of the polynomial x3 + 5x2 + 6x is (x2 + 3x). What is the other factor?
butalik [34]

Answer:

x+2

Step-by-step explanation:

Dividing the poly by the known factor:

x3+5x2+6x    <u>| x2+3x</u>

-x3-3x2             x + 2  <- the answer is here

      2x2+6x

      -2x2-6x

To prove that, let's multiply the two factors and find the pylonomial back on:

(x2+3x).(x+2) = x3 + 2x2 + 3x2 + 6x = x3 + 5x2 + 6x

Tks your attention!
