Answer:

5. B, 21

6. C, 16

Step-by-step explanation:

5. 11 - 11 = 0, |0| = 0

33 - 12 = 21, |21| = 21

0 + 21 = 21

6. -3 \frac{1}{2} - 2 = -5 \frac{1}{2}, |-5 \frac{1}{2}| = 5 \frac{1}{2}

13 \frac{1}{2} + -3 = 10 \frac{1}{2}, |10 \frac{1}{2}| = 10 \frac{1}{2}

5 \frac{1}{2} + 10 \frac{1}{2} = 16

. The ratio of the area of circle A to the area of circle B is 12/5. What is the ratio of their circumferences?
N76 [4]

Answer:

1.5

Step-by-step explanation:

a : b = 1 : 12/5

Area of a circle = πr²

Where : = π = pi = 22/7

R = radius  

Let the radius of circle a = 1

Area of circle A = 1π

Radius of circle A = square root of 12/5 = 1.5

The circumference of a circle = 2nr

n = 3.14

circumference of circle A = 2 x n x 1 = 2n

circumference of circle B = 2 x n x 1.5 = 3n

ratio of circumference = 3n / 2n = 1.5

Answer please I’m really struggling with this
katovenus [111]

To write the any polynomial in standard form you must first put it in terms separated only by +,- operators, then you must order terms x^n descendingly according to n. In your case -\frac{1}{5}x^2 will be the first term because it has highest power, followed by -8x^1 and +7x^0.

The standard form of this specific polynomial is:

-\dfrac{1}{5}x^2-2x+7.

Hope this helps.
