Answer:
do u have a graph
Step-by-step explanation:
Answer:
a) 186
Step-by-step explanation:
g(x) = 7(x^2 + 3) - 10
g(5) = 7((5)^2 + 3) - 10
g(5) = 7(25 + 3) - 10
g(5) = 7 × 25 + 7 × 3 - 10
g(5) = 175 + 21 - 10
g(5) = 186
LW = A
L(L - 3) = 18
L^2 - 3L - 18 = 0
(L - 6) (L + 3) = 0
L could be 6 or -3 ( -3 cannot be a length of a side of a rectangle since it’s negative.)
So L = 6 and W= 3
[] signs mean that the number is included in the domain and () mean that the number is not included. Now,
1. [-1,5)
Because x is greater than or equal to -1 (included) but less than 5 (excluded
2. [-5,13)
When we plug in x = -1, we get the minimum value of -5, which is included because its x-value was included. The, we plug in x = 5 to find the range's maximum and this is excluded because its x-value was excluded.
3. 218
x = 6 lies in the domain of the first function so we will use it to evaluate the value of x = 6. We do this by simply substituting x into the function.
4. 12
x = 9 is included in the domain of the second function and the value of the second function at all points is 12.
5. 103
x = 10 is included in the domain of the second function so we will use it to evaluate the value of x = 10. This is done by substituting x into the equation.
Athe answer is -2 because it is behind the 0 and will be negative and it is two lines away from the 0 so the answer is -2
