Answer:
The desired quotient is 25/12.
Step-by-step explanation:
Rewrite 1 2/3 as an improper fraction: 5/3.
Then divide this 5/3 by 4/5:
5
------ ÷ 4/5
3
It's easier (but completely correct) to invert the divisor (4/5) and then multiply 5/3 by (5/4):
5 5 25
----- * ----- = ------
3 4 12
Answer:
.173 seconds or a negataive
Step-by-step explanation:
Your formula would be
h = -16t^2 - 55t + 10
when it hits the ground h = 0
16t^2 + 55t - 10 = 0
t = (-55 ± √3665)/32 = .173 seconds or a negataive
Simple...

What multiplies to -18 but adds to -7?
-9*2=-18
-9+2=-7
Leaving you with...
(y-9)(y+2)
As we can see the grouped factoring is not all negative...
Thus, your answer.
Answer:
Yes it has
Step-by-step explanation:
From my perspective.........
f(x) = -4(x + 3)² - 5
f(x) = -4(x + 3)(x + 3) - 5
f(x) = -4(x² + 6x + 9) - 5
f(x) = -4x² - 24x - 36 - 5
f(x) = -4x² - 24x - 41
Dy/dx = -8x - 24
At minimum Dy/dx = 0
-8x - 24 = 0
-8x = 24
x = 24/-8
x = -3
At minimum
y = -4x² - 24x - 41
y = -4(-3)² - 24(-3) - 41
y = -4(9) + 72 - 41
y = -36 + 72 - 41
y = 36 - 41
y = -5
