Answer:

2

Step-by-step explanation:

17 - 5(3) (Plug in)

= 17-15 (Multiply)

= 2 (Simplify)

Answer:

Part A: d ≥ 500

Part B: d must be over or equal to 500 but can go infinity at 500+

Step-by-step explanation:

Part A:

≥ stands for "at least" and d has to be "at least" 500,

hence d ≥ 500

Answer:

I think so is it is not a right triangle or a specific type of triangle

Each answer has 7 as the base and a fraction as an exponent.

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

Explanation:

One useful rule here is that [tex]\sqrt[n]{x^m} = x^{m/n}[/tex]. The fraction m/n is the exponent for the base x. Note how the index of the root (n) becomes the denominator of the fraction m/n. So for example if we had n = 3, then we'd be dealing with a cube root.

For part a), we have x = 7, m = 1 and n = 5 to get

[tex]\sqrt[n]{x^m}=x^{m/n}\\\\\sqrt[5]{7^1}=7^{1/5}\\\\\sqrt[5]{7}=7^{1/5}\\\\[/tex]

-----------------

Part b) is the same idea

We would find that

[tex]\sqrt[n]{x^m}=x^{m/n}\\\\\sqrt[7]{7^1}=7^{1/7}\\\\\sqrt[7]{7}=7^{1/7}\\\\[/tex]

Then apply the reciprocal to both sides. This is the same as raising both sides to the exponent -1

[tex]\sqrt[7]{7}=7^{1/7}\\\\\left(\sqrt[7]{7}\right)^{-1}=\left(7^{1/7}\right)^{-1}\\\\\frac{1}{\sqrt[7]{7}}=7^{1/7*(-1)}\\\\\frac{1}{\sqrt[7]{7}}=7^{-1/7}\\\\[/tex]

You could also use the rule that x^(-y) = 1/(x^y) when dealing with negative exponents.

In the second to last step shown above, I used the rule (x^y)^z = x^(y*z) on the right hand side.

Answer:

2x+5

Step-by-step explanation:

Okay so lets first factor 2x^2+15x+25

2*25=50

10+5=15

10*5=15

(x+10/2)(x+5/2)

=(x+5)(2x+5)

we know that the width is x+5 so that means the length has to be 2x+5

Step-by-step explanation:

Surface area = 4*lateral faces + 2*bases

Answer:

168.168 square inches

Step-by-step explanation:

Given data

From the question, we can deduce that the side of the square is 28in

Hence the area of the square is

Area= 28^2

Area= 784 square inches

Also, the diameter of the circle is 28 in

The radius = 14 in

Area of circle= πr^2

Area= 3.142*14^2

Area= 3.142* 196

Area= 615.832 square inches

Therefore the area of the shaded region is

= Area of Square - Area of Circle

= 784-615.832

=168.168 square inches

Answer:

−22

Answer:

x=10

y=40

Step-by-step explanation:

The shape is a parallelogram, therefore we know that opposite sides are equal to each other. So,

x + 18 = 3x - 2

Add 2 to both sides and subtract x from both sides

20 = 2x

divide both sides by 2

10 = x

Now, we have the other two sides;

4x = y

We already know that x = 10, so just plug that into the equation.

4(10) = y

40 = y

Step-by-step explanation:

Area of the square:

a^2: 4^2=16in^2

Area of the circle:

πr^2: π(4.5)^2= 63.6

Area of white part:

63.6 - 16 = 47.6

Probability of landing on square:

16/63.6 = 0.25

Probability of landing on white part:

63.6/16 = 3.975

Answer:

C. 9

Step-by-step explanation:

the answer cant be 7 its not marked on the line

it would not be 8 because the circle is not closed therefore its not equal to wich means 8 it not right
