Answer:
Check bolded below
Step-by-step explanation:
1)radius = 10 in (given), diameter = 2*radius = 2(10 in) = 20 in
formula for circumference => 2πr => 2π(10)
circumference = 20π in
2)diameter = 12 ft (given), radius = 1/2*diameter = 1/2(12 ft) = 6 ft
formula for circumference => 2πr => 2π(6)
circumference = 12π ft
3)radius = 3 m (given), diameter = 2*radius = 2(3 m) = 6 m
formula for circumference => 2πr => 2π(3)
circumference = 6π m
4)diameter = 18 cm (given), radius = 1/2*diameter = 1/2(18 cm) = 9 cm
formula for circumference => 2πr => 2π(9)
circumference = 18π cm
If $1 is 5%, 100% would be $1 times 100/5= $1 times 20 = $20
Answer:
336
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
original formula is: y - y1 = m (x - x1) ordinates= (x1, y1)
insert the a corresponding x and y coordinate:
y + 3 = -2 (x + 9)
Don't forget to change the signs depending on whether their positive or negative:
(3, -9) since 3 is positive but there is a minus in the formula it would be -3
since -9 is negative and in the equation there's a minus sign you would change it to positive. (negative times a negative equals a positive)
Answer:
r² + 9r + 6
Step-by-step explanation:
+3| +1 +6 -21 -18
|<u> +3 +27 +18</u>
+1 +9 +6 0
Answer:
=1r² +9r + 6 + 0
=r² +9r + 6 (simplified)
Read on if you want to know how it was done.
To do synthetic division, you first need to get the constant of the divisor and change the sign.
Then list the coefficients of the dividend.
Drop the first coefficient.
Multiply it by the divisor, and write the answer under the next coefficient and add. Repeat till the end.
The answer should be one degree less, the original polynomial.
