Given that f(x) = 3x + 1 and g(x) = the quantity of 4x plus 2 divided by 3 , solve for g(f(0)). (5 points) 2 6 8 9
leva [86]

f(0)=3(0)+1

f(0)=1

g(1)=\frac{4(1)+2}{3}

g(1)=\frac{4+2}{3}

g(1)=\frac{6}{3}

g(1)=2

Hope this helps.

In the 30-60-90 triangle below, side s has a length of ___ and side q has a length of ___.
KIM [24]
In a 30-60-90 triangle:
the side opposite of the 30 degree angle has a length of "b"
the side opposite of the 60 degree angle has a length of "b√3"
the side opposite of the 90 degree angle has a length of "2b"

The given value of 8 is opposite of the 90 degree angle, so 8 = 2b → 4 = b
Now, plug in 4 for b to determine the lengths of the other sides.

s is the side opposite of the 30 degree angle which has a length of "b"
so, s is 4

q is the side opposite of the 60 degree angle which has a length of "b√3"
so, q is 4√3

Answer: F

There are 4 identical wooden blocks that are 20 inches long, 2 inches
Talja [164]

Answer:

Step-by-step explanation:

Each block has two 20×1 faces, two 20×2 faces, and two 2×1 faces.

Surface area of one block = 2(20×1) + 2(20×2) + 2(2×1) = 124 sq in

Total surface area = 4(124) = 496 sq in.

Largest surface area: Assemble the blocks end-to-end into a block that is 80 by 2 by 1. Six of the 2 by 1 faces are hidden, so the surface area is 496 - 6(2×1) = 484 sq in.

Smallest surface area: Assemble the blocks into a block that is 20 by 4 by 2. Four of the 20 by 2 faces and four of the 20 by 1 faces are hidden, so the surface area is 496 - 4(20×2) - 4(20×1) = 256 sq in.

Difference in surface area = 484-256 = 228 sq in.
