• Answer:
99
• Step-by-step explanation:
Hi there !
use formula a² - b² = (a-b)(a+b)
18² - 15² =
= (18 - 15)(18 + 15)
= 3×33
= 99
Good luck !
The zeros of a function are the values of x that make the function be equal to zero.
When graphing a quadratic equation, the graph is a parabola, and the zeros of the function are the x-intercepts of the graph, which are the points where the graph intersects the x-axis.
So, if the zeros of this function are x = -8 and x = 2, that means the parabola crosses the x-axis at x = -8 and x = 2.
Therefore the correct option is the first one.
Answer:
Its 1
Step-by-step explanation:
Prime factorization
45 = 3 × 3 × 5
56 = 2 × 2 × 2 × 7
To find the gcf, multiply all the prime factors common to both numbers
Therefor, it equals 1
A. Write a function f(x) to represent the price after the 80% markup.
<span>b. Write a function g(x) to represent the price after the 25% markdown. </span>
<span>c. Use a composition function to find the price of an item after both price adjustments that originally costs the boutique $150. </span>
<span>d. Does the order in which the adjustments are applied make a difference? Explain.
</span>
answers
<span>a) f(x) = 1.8x
b) f(x) = 0.75(1.8x)
c) f(150) = 0.75(1.8(150) = $202.50
d) No, it doesn't matter. The result is the same.
</span>
F(x) is decreasing in the interval: - 6 < =x< - 5.1
f(x) is increasing in the interval: - 5.1 <x< - 3.5
the point of inflection is the point where the graph changes its "direction"
thus the point of inflection is x= -5.1
