The diameter of a circle is 3.2 meters. Which is the circumference of the circle rounded to the nearest hundredth of a meter?
Paraphin [41]

Answer:

10.05 meters

Step-by-step explanation:

If the diameter is 3.2 meters, then the radius is 1.6 meters.

Use the circumference formula, C = 2\pir, and solve for C

C = 2\pir

C = 2\pi(1.6)

C = 3.2\pi

C = 10.05

So, to the nearest hundredth of a meter, the circumference is 10.05 meters

Help with #9 linked above! Please help!
jasenka [17]

y = A(Bx - C)ⁿ + D

A is a vertical stretch (or shrink if |A| < 1)

B is a vertical shrink (or stretch if |B| < 1)

C is a shift to the right (or left if C is negative) → notice that Bx - C is "-C" so to take the opposite

D is a shift up (or down if D is negative)

when C = -3, it is a shift to the left 3 units

when D = -7, it is a shift down 7 units

Please help me on this question
Masja [62]

Answer:

The number is 5

Step-by-step explanation:

Let x be the number

3x+5+x = 25

Combine like terms

4x+5 = 25

Subtract 5 from each side

4x+5-5 = 25-5

4x = 20

Divide by 4

4x/4 = 20/4

x = 5

Find the sum of 7a^3 + 14a +12 and -6a^3 +12a^2 -7
SOVA2 [1]
To find the sum:

{7a}^{3} + 14a + 12  + ( {- 6a }^{3} ) + {12a }^{2}   - 7 \\  = {7a }^{3}   -  {6a}^{3}  + {12a }^{2}  + 14a + 12 - 7 \\  =  {a}^{3}  + {12a }^{2}  + 14a + 5
Therefore the answer is a^3+12a^2+14a+5.
Hope it helps!
