Answer:
3375
Step-by-step explanation:
The surface area formula for a cube is:
A = 6 a^2
We know what the area is so plug it into the equation:
1350 = 6 a^2
225 = a^2
a = 15
Now plug a = 15 into the equation for volume of a cube:
V = a^3
V = 15^3
V = 3375
55 mph minus 40 mph = 15 miles distance for each hour
So 5 hours * 15 = 75 miles difference after 5 hours
F(x)=1/(x-3)^3
The denominator can't be equal to zero (we can't divide by zero), then:
(x-3)^3 different 0
cubic root both sides:
cubic root [ (x-3)^3 ] different cubic root (0)
x-3 different 0
Adding 3 both sides:
x-3+3 different 0+3
x different 3
Then the function f is not defined at x=3
Answer: Option <span>b) f is not defined at x= 3</span>
Please try leaving out the "I'm so bad at math" part. It doesn't help.
The given inequality is <span>4x + y > −6. Because of the > symbol, we must use a dashed line, not a solid one. Let's solve this for y: y > -4x - 6.
This (dashed) line has a slope of -4 and a y-intercept of (0,-6).
Plot (0,-6). Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down. Plot a new point there, at (1, -10). Draw your dashed line thru those 2 pts. Then, because we have y > -4x - 6, shade the area ABOVE this line. Done.</span>
