I have 183 feet of fencing. The length of the court is 32 feet more than the width. One of the shorter sides will be 5 feet shor
Aliun [14]
Okay so the total is 183. So we can say 183 = 
Let's call the width (the longer side) x.
We know that we have x, x + 32, and x - 5.
We can say 183 = x + (x + 32) + (x - 5).
Let's solve for x.
x = 52. 
So we know the length is 84 feet, the shorter side has 47 feet, and the longer side has 52 feet.

Given the following sequence, find the 23rd term: 10.5, 11, 11.5, 12, 12.5, . . .
4vir4ik [10]
10.5, 11, 11.5, 12, 12.5...this is an arithmetic sequence with a common difference of 0.5

an = a1 + (n - 1) * d
n = term to find = 23
a1 = first term = 10.5
d = common difference = 0.5

sub and solve

a(23) = 10.5 + (23 - 1) * 0.5
a(23) = 10.5 + 22 * 0.5
a(23) = 10.5 + 11
a(23) = 21.5 <===

A carpenter is building a rectangular shed with a fixed perimeter of 54 ft. What are the dimensions of the largest shed that can
lutik1710 [3]

Answer:

the Largest shed dimension is 13.5 ft by 13.5 ft

Largest Area is 182.25 ft²

Step-by-step explanation:

Given that;

Perimeter = 54 ft

P = 2( L + B ) = 54ft

L + B = 54/2

L + B = 27 ft

B = 27 - L ------------Let this be equation 1

Area A = L × B

from equ 1, B = 27 - L

Area A = L × ( 27 - L)

A = 27L - L²

for Maxima or Minima

dA/dL = 0

27 - 2L = 0

27 = 2L

L = 13.5 ft

Now, d²A/dL² = -2 < 0

That is, area is maximum at L = 13.5 using second derivative test

B = 27 - L

we substitute vale of L

B = 27 - 13.5 = 13.5 ft

Therefore the Largest shed dimension = 13.5 ft by 13.5 ft

Largest Area = 13.5 × 13.5 = 182.25 ft²

Please oh please help me I don’t want too fail!
SCORPION-xisa [38]

Answer:

D

Step-by-step explanation:

The best bet would be D because if its going counterclockwise 360 degrees then it would make a full rotation going back to the same position although I would work out the problem to the best of your ability just to make sure because I'm not entirely sure about my answer.
