Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(L +W)
Given L = W + 2 and the perimeter is greater than 112 meters?
P rect < 2(L +W) L = W + 2
P rect < 2(W + 2 +W)
< 2(2W+2)
112 < 4W + 4 solve for W
(112 - 4)/4 < (4W +4 - 4)/4
108/4 < (4W + 0)/4
27 < W
the width has to be greater than 27 meters
Answer:
Step-by-step explanation:
Unclear. Did you mean f(x) = 2^(x + 3)? If so, the parentheses are mandatory.
Assuming that f(x) = 2^(x + 3) is correct, then:
a) f(2) = 2^(2 + 3) = 2^5 = 32
b) f'(x) = 2^(x + 3)*(x + 3)' = 2^(x + 3)(1) = 2^(x + 3)
c) f"(x) = 2^(x + 3) (same as in (b)), so that:
f"(12) = 2^15
Answer:
A
Step-by-step explanation:
The formula of circumference: 2兀r
Take 3.14 as 兀
Circumference of circle with radius 4.2 units
=4.2x2x3.14
=26.376units
Circumference of circle with diameter 7.4
=7.4x3.14
=23.236 units
Circumference of circle with diameter 11 units
=11x3.14
=34.54 units
Circumference of circle with radius 9.5 units
=9.5x3.14
=29.83 units
Hope it helps!
