Answer:
Step-by-step explanation:
(a) The appropriate formula is C = 2πr. Here r = 14 cm, so
C = 2π)14 cm = 28π cm, or (if we take π to be 22/7), C = 88 cm²
(b) We use the same circumference formula: C = 2πr and solve it for r before inserting numeric values:
C 132 m 7(132 m)
r = -------- and in this case, r = ------------------- = ------------- = 21 m
2π [ 2 * (22/7) ] 44
-4 = 6 + b equals -10=b
Your subtract 6 from both sides and that gives you -4-6 which is -10
Answer:
Width=13 Length=25
Step-by-step explanation:
The total perimeter of the field is 76 feet.
Lets say that is length is X and the width is Y.
The equation would be:
2Y+2(12+Y)=76
First solve for the parenthesis.
2Y+24+2Y=76
76-24=52
52=4y
y=13
To check your answer, 13 times 2 (26) plus 25 times 2 (50)= 76 so we know this is correct.
F(x) =-5x+9
f(x) =-5(15)+9
f(x) =- 75+9
f(x)=-66
your answer is -66 :)
P(x > 10.52) ≈ 0.289%
