Answer:
if you are asking for the real number, the answer would be 45.21
Step-by-step explanation:
We simply multiply by 10 since we are given 1 as an exponent
Answer:
A factor of f(x) is (x + 1).
Step-by-step explanation:
When we put x+1= 0 then we get the value x= -1
This value is then put into the function to find out whether it is a root or not. For a root to exist it must not have a remainder or the remainder must be zero.
Suppose the function is
F(x)= 2x³ - 42x - 40
f(-1)= 2(-1)³ - 42(-1) - 40
f(-1)= -2 + 42- 40
f(-1)= 0
This gives -1 as the root of the function.
Answer:
Step-by-step explanation:
Given Equation of line: y=mx+c,
where m = slope of line.
So, we will have to make y the subject to find the slope.
From here, we can see the slope of the line is .
Answer:
g(f(- 2)) = 91
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x), that is
f(- 2) = - 2 + 7 = 5 , then
g(5) = 4(5)² - 9 = 4(25) - 9 = 100 - 9 = 91
7P3= 7!/(7-3)!
= 7!/4!
= 7*6*5
= 210
C.210
