Answer:
First equation: 4n^2=256
Second equation: 4n*2=64
Step-by-step explanation:
First equation:
4n^2 for n = 8.
Substitute 8 for n and solve:
4*(8)^2=4*64=256
4n^2=256
Second equation:
4n*2 for n = 8.
Substitute 8 for n and solve:
4*(8)*2=32*2=64
4n*2=64
I hope this helped you.

Answer:
16.50 dollars
Step-by-step explanation:
e : d
8 : 11
From 8 to 12 you /2/3 do the same to 11 /2/3
12 : 11/2/3
12 : 16.5
Answer:
C.) -1/2
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes.
- Opposite = opposite signs (+ & -)
- Reciprocal = flipped positions in fractions (1/2 ⇒ 2/1)
Therefore, the slope of a line perpendicular to the line y = 2x - 3 must be -1/2.
Answer:
30.17feet high
Step-by-step explanation:
Given the following
the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)
angle of elevation = 38°
Required
Height of the flagpole (opposite)
Using the SOH CAH TOA identity
Sin theta = opposite/hypotenuse
Sin 38 = H/49
H = 49sin38
H = 49(0.6157)
H = 30.17feet
Hence the flagpole is 30.17feet high
