Parallel lines have the same gradient so it’s the second or the fourth answer.
y = mx + c
y = 2x + c
3 = (2 x 2) + c
3 = 4 + c
3 - 4 = c
c = -1
y = 2x - 1
Answer:
65.426
Step-by-step explanation:
Given that:
Mean height (m) = 68 inches
Standard deviation (s) = 2 inches
Height required to be taller than 90% of the class :
P(Z > x) = 0.9
The corresponding Zscore is - 1.282 (Z probability calculator)
Using the Zscore relation :
Zscore = (x - m) / s
-1.282 = (x - 68) / 2
-1.282 * 2 = x - 68
-2.564 = x - 68
-2.564 + 68 = x
x = 65.436
Answer:
84.8 sq in
Step-by-step explanation:
The area of the top and bottom are each 1/2(3.7 x 4) = 7.4, so they total 14.8
2 of the sides are 5 x 5 = 25, so they total 50
1 side is 5 x 4 = 20
14.8 + 50 + 20 = 84.8 sq in
Your answer is 472,441 inches
Hope this helps!!!!!!!!
Answer:
g(x)=8x+16 for x= -3, 0, and 8.
g(-3) = -8
g(0)= 16
g(8)= 80
Step-by-step explanation:
Step 1. Plugin the given numbers.
g(-3)= 8(-3) + 16
g(0)= 8(0) + 16
g(8)= 8(8) + 16
Step 2. Solve the equations.
g(-3)= -24 + 16 Multiplied -3 and 8.
g(-3)= -8 Added -24 and 16
g(0)= 0+16 Multiplied 0 and 8.
g(0)= 16 Added 16 and 0.
g(8)= 64+16 Multiplied 8 and 8.
g(8)= 80 Added 64 and 16.
