Answer:
- The function is a linear function.
- The function changes at a constant rate.
Step-by-step explanation:
The degree of x is 1, so the function is a linear function.
The coefficient of x is -90, a constant rate of change that is negative, so the function is <em>decreasing</em>.
Answer:
x = 12
WN = 28
Step-by-step explanation:
SO = WN and SO = 2WI
3x - 8 = 2(x + 2)
3x - 8 = 2x + 4
3x - 2x = 4 + 8
x = 12 now replace x with 12 in the first equation given
3x - 8 = 3×12 - 8
36 - 8 = 28
Answer:
8(4g+3c)
Step-by-step explanation:
Answer:
2x + 11 (brainliest?)
Step-by-step explanation:
6x - 4x = 2x
2 - - 9 = 11
2x + 11
We know that
<span>the sphere is divided into two hemispheres
</span><span>the two hemispheres are equals
</span><span>
if </span><span>Tran computes the amount of paint needed to cover the sphere
</span><span>therefore
</span>Tran computes the amount of paint needed to cover <span>both hemispheres.
</span>
the answer is
Tran found the minimum amount of paint needed to cover both hemispheres.
[surface area of sphere]=4*pi*r²
[surface area of each hemisphere]=2*pi*r²
circumference=18.84 cm------> 2*pi*r------> r=18.84/(2*pi)------> 3cm
[surface area of each hemisphere]=2*pi*3²---------> 56.52 cm²
surface area of sphere=2*56.52=113.04 cm²
