Step 1: find the area of the base
A=l*w = 8.25*5.5 = 45.375
Step 2: find the perimeter of the base
P=2l+2w = 2(8.25) + 2(5.5) = 16.5 + 11 = 27.5
Step 3: find the surface area of the prism
SA=2A+Ph = 2(45.375) + 27.5(4.5) = 90.75 + 123.75 = 214.5
Hope this helps
Answer:
BCG =65
Step-by-step explanation:
DCG + GCB = DCB
We know BCG = 31x+3 and GCD = 12x+2 and BCD = 91
Substituting these in
12x+2 + 31x+3 = 91
Combine like terms
43x +5 = 91
Subtract 5 from each side
43x+5-5 = 91-5
43x = 86
Divide by 43
43x/43= 86/43
x=2
BCG = 31x+3
=31(2)+3
=62+3
=65

a) There is sufficient evidence to reject the claim that the two methods provide the same mean value for natural vibration frequency.
b) (-10.9646, -0.0068)
Answer:
C
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 3, 9) and (x₂, y₂ ) = (3, 1)
d =
