Answer 1

Answer:

Answer:

D would be the answer

Step-by-step explanation:

since you have a positive 12 at the end of your equation(thats your y intercept 0,12) then you can eliminate A, B. Next you would plug in (-3,0) in your equation and see if it would work and it did so thats your answer. ( i know thats not the formal way to do it but its a shortcut i like to use ;)

A radius is a segment that connects any point on the circle to the center of that circle.True or False?

Answers

Answer:

True

Step-by-step explanation:

First let's understand the definition of circle.

A circle is a round plane figure. It is set of points moving from the center at equal distance. If we connect the points we get a circle.

The distance from the center and any points on the circle is called radius.

In other words, a line segment that is connecting the center of a circle and any point on the circle is called radius.

Radius is half of the diameter.

R = D/2, where D is the diameter of the circle.

Therefore, the statement is true.

Yes, it's true.

That is the definition of the radius: The segment that connects any point on the circle with the center of the circle

Because you round 253 down to 250 and 46 down to 45

Which polynomial is a difference of squares? A.x2 – 16x + 64
B.x2 + 4
C.9x2 – x – 36
D.25x2 – 36

Answers

Answer

D.25x2 – 36

Explanation

A. x² – 16x + 64

product = 64

sum = -16

factors: -8 and -8

x² – 16x + 64 = x² - 8x - 8x + 64

= x(x - 8) - 8(x - 8)

= (x - 8)(x-8) = (x-8)² ⇒ Not a difference of squares

B.x² + 4 = (x² + 2²) ⇒ Not a difference of squares

C.9x² – x – 36

product = - 324

sum = -1

Factors: none

9x² – x – 36 ⇒ Has no perfect roots.

D.25x² – 36

25x² – 36 = (5x)² - 6² ⇒ This is the difference of squares.

Hello,

Answer D

25x²-36=(5x)²-6²

Well if she saved $8 for buying it on 25% off, and since 25% = 25/100 = 1/4, you do 8/(1/4) = 8(4) = 32

Put 983 in scientific notation.

Answers

To the left of the decimal point needs to be somewhere between 1 and 9 (one place). 983 in scientific notation would be 9.83 x 10^2. Do you understand how i got that? I got the 10^2 because i am moving the decimal point over two places to the left. If i move the decimal point to the right, then the exponent would be negative. Example:
0.00983 in scientific notation would be 9.83 x 10^-3 because i moved the decimal point three places to the right.

9.83• ten to the negotiation two
