Hello from MrBillDoesMath!
Answer:
9, 11
Discussion:
From the attachment,
P = w + l + w + l
= 2w + 2l => as l = w + 2
= 2w + 2( w+2)
= 4w + 4
= 40 (given value)
4w + 4= 40 => subtract 4 from both sides
4w = 40 -4 = 36 => divide both sides by 4
w = 36/4 = 9
This implies that l = w+2 = 9 + 2 = 11
Thank you,

Answer:
21.25 m
Step-by-step explanation:
y = Ax² + Bx + C
Set the origin at the middle of the span so that the point (0, 0) is on the curve
0 = A(0)² + B(0) + C means C = 0
The points (200, 85) and (-200, 85) are on the curve
85 = A(200)² + B(200)
85 = A(-200)² + B(-200)
85 - 40000A - B(200) = 85 - 40000A + B(200)
- B(200) = B(200)
-400B = 0
B = 0
85 = A(200)²
A = 85/40000
y = 85x²/40000
y = 85(100)²/40000 = 21.25 m
Answer:
$122.9
Step-by-step explanation:
Given data
Principal= $114
Rate= 3.9%
Time= 2 years
The amount in the account is given as
A=P(1+rt)
substitute
A=114(1+0.039*2)
A=114(1+0.078)
A=114(1.078)
A=$122.9
