Answer:
yes, your friend is correct
Step-by-step explanation:
14 x 4 = 56 and 25 x 4 = 100
56
------ = 0.56 in decimal form
100
Solve for h by simplifying both sides of the equation,then isolating the variables
2πrh,
h=-2πr^2+sa
The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120
Answer:
Since the graph never crosses the x-axis, the function has no real zeros
Step-by-step explanation:
The real zeros <em>are</em> the x-intercepts.
This graph has neither. Since the graph never crosses the x-axis, there are no real zeros.
Answer: X=16
Step-by-step explanation: Add 90 and 22 and you will get 112. Since the beginning of the equation is "7x" which is multiplication you use Inverse Operations. So, you divide the sum, 112, by 7. Your answer will be 16.
