Answer:
10 %
Step-by-step explanation:
let the percent be x
according to the question
7.8 = x % 0f 78
7.8 = x /100 * 78
7.8*100 = 78x
780 = 78x
780/78 = x
10 = x
I can answer but ur not being specific it what is the 6 for and what is the 2 for because there’s a space
Answer:
see explanation
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² - 3x - 4 = 0
Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)
The factors are - 4 and + 1, since
- 4 × 1 = - 4 and - 4 + 1 = - 3, thus
(x - 4)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 1 = 0 ⇒ x = - 1
x- intercepts are (- 1, 0 ) and (4, 0 )
If the slice is made parallel to the base, then if the base is a rectangle, the cross-section would be A. rectangle
