Answer:
(0.353, -48)
Step-by-step explanation:
dy/dx = 9x² + 28x - 11 = 0
Using the quadratic formula:
x = -3.46 and 0.353
d²y/dx² = 18x + 28
Minima when d²y/dx² is positive
x = 0.35284 or (-14+sqrt(295))/9
y = 3x³ + 14x² - 11x - 46
y = -48.00651351
Answer:
side AC is 5
Step-by-step explanation:
by using th pythagorean theorm you would square both sides add them together and the square root the sum to get you answer.
AB =3 BC=4
9+16=25
25 square root is 5
makeing AC=5
Idk this one REEE! i’m so sorry i can’t help :(
Let's do this step by step:
20-3(m-1)=-4
20-3m+3=-4
23-3m=-4
-3m=-27
m=9
To check if this answer is correct, simply substitute m with 9 and you will get 9=9
