The piecewise defined function f(x) is graphed below. What is the value of f(2)?


f(2) = –2
f(2) = –1
f(2) = 4
f(2) is undefined

Here we just want to find the perimeter of the image below.

We will find that the correct option is D.

The perimeter will be equal to:

The perimeter of a square of side length of 13 ft, minus 5 ft (the diameter of the circle), plus half the perimeter of a circle of diameter 5ft.

Remember that for a square of side length L, the perimeter is:

P = 4×L

For a circle of diameter D, the perimeter is:

P = 3.14*D

Then the perimeter of the square of side length of 13ft is:

P = 4×13ft = 52ft

The perimeter of the half-circle of diameter 5ft will be:

P' = 3.14×5ft/2 = 7.85ft

Then, the perimeter of the whole figure is:

perimeter = 52ft - 5ft +  7.85ft = 54.85ft

Rounding to the nearest whole number, we get:

54.85ft ≈ 55ft

The correct option is D.

Answer: 81

Concept:

When a number is being squared, to being put to any power, it means the number multiplies itself by the amount of times indicated by the exponent.

For example, if 3 is to the 3rd power, then it would appear to be 3 × 3 × 3.

Please let me know if you have any questions

I believe this is the expression:

[tex] \displaystyle \large \boxed{ - 8 {y}^{2} }[/tex]

Since we want to evaluate it when y = -2, simply substitute y = -2 in the expression.

[tex] \displaystyle \large{ - 8 {( - 2)}^{2} }[/tex]

Any negative number squared will result in positive, refer below:

[tex] \displaystyle \large{ {( - a)}^{2} = {a}^{2} } \\ \displaystyle \large{ {( - 2)}^{2} = {2}^{2} } \longrightarrow \boxed{4} \\ [/tex]

Hence,

[tex] \displaystyle \large{ - 8(4) = - 8 \times 4} \\ \displaystyle \large \boxed{ -32}[/tex]

Answer:

-32

Step-by-step explanation:

Replace the variable y with -2 in the expression giving -8(-2)^2

Then, square -2 giving us (positive) 4

Lastly, multiply -8 with 4 and get -32 as our answer

Answer:

no solutions

Step-by-step explanation:

4z - 15 = 4z+11

Subtract 4z from each side

4z-15-4z = 4z+11-4z

-15 = 11

This is not a true statement so there are no solutions

Answer:

No solutions.

Step-by-step explanation:

4z-15=4z+11  Subtract 4z from both sides.

-4z      -4z

-15=11             This statement is not true; therefore, there are no solutions.

Answer:

m∠A = 65°

Step-by-step explanation:

Because ∠CBD is congruent to ∠DBE, we can set the degree values equal to each other.

So

CBD has x + 10, DBE has 60. So:

x + 10 = 60

Subtract 10 from both sides.

x = 50

Check:

50 + 10 = 60

60 = 60

m∠A = (x + 5)° = (60 + 5)° = 65°

The measure of m<A if angle CBD = angle DBE is 55°

The point where two lines meet is known as an angle.

We are given the following from the diagram:

m<CBD = x +10

m<DBE = 60degrees

Since  angle CBD = angle DBE, then:

x + 10 = 60

x = 60 - 10

x = 50degrees

Get the angle A.

From the diagram, angle A = (x+5)°

m<A = 50 + 5

m<A = 55°

Hence the measure of m<A is 55°

Refer to the attached diagram for further a visual explanation. As per the given information, segments (AB) and (AD) are congruent. Moreover, segments (AC) and (AE) are also congreunt. One is also given that angles (<BAD) and (<EAC) are congruent. However, in order to prove the triangles (ABC) and (ADE) are congruent (using side-angle-side) congruence theorem, one needs to show that angles (<BAC) and (<DAE) are congruent. An easy way to do so is to write out angles (<BAC) and (<DAE) as the sum of two smaller angles:

<BAC = <BAD + <DAC

<DAE = <DAC + <EAC

Both angles share angle (DAC) in common, since angles (<EAC) and (BAD) are congruent, angles (<BAC) and (<DAE) must also be congruent.

Therefore triangles (ABC) and (ADE) are congruent by side-angle-side, thus sides (BC) and (DE) must also be congruent.

In summary:

AB = AD                                               Given

AC = AE                                               Given

<BAD = <EAC                                      Given

<DAC = <DAC                                     Reflexive

<BAC = <BAD + <DAC                       Parts-Whole Postulate

<DAE = <EAC + < DAC                       Parts-Whole Postulate

<BAC = <DAE                                      Transitivity

ABC = ADE                                          Side-Angle-Side

BC = DE                                               Corresponding parts of congruent triangles are congruent
