Answer:
-18.289
Step-by-step explanation:
From SOHCAHTOA,
using CAH which is COS
CAH=adjacent/hypotenuse
cos 28°=x/19
19cos28°=x
x=19cos28°
x=-18.289
Answer:
x = - 2 or x = 4
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
The x- intercepts are at x = - 2, x = 4
Explanation:
The test grade for 1st three tests = 62, 85, 89
Let the fourth test score = x
The result we hoping to get is grade B.
Let's find the average of the four test score
