Answer:
144
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
4(t -1)² = 4(7 -1)² = 4(6²) = 4(36) = 144
The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
Answer:
all real number
Step-by-step explanation:
since h(x) is polynomial function
Solution:
f(x) = 2x + 3
g(x) = x - 9
f(x) + g(x)
= (2x + 3) + (x - 9)
= 2x + x + 3 - 9
= 3x - 6
Um i think that would probably be something like 2.2
