Important: Use the symbol "^" to denote exponentiation:
<span>x3 – 9x2 + 5x – 45 NO
</span><span>x^3 – 9x^2 + 5x – 45 YES
Look at the first 2 terms. They can be rewritten as x^2(x-9). Then look at the last 2 terms. They can be rewritten as 5(x-9). So, x-9 is the common factor here. Thus, the original expression becomes:
(x^2-5)(x-9).
Note that x^2-5 can be factored, so that the final 3 factors are:
(x-sqrt(5)), (x+sqrt(5)), (x-9).</span>
vertex form of a parabola
y= a(x-h)^2 +k
y =a(x--3)^2 +2
y = a(x+3)^2 +2
Choice B
It's C i took the test......
Answer:
The slope of the line that passes through these two points is 2/5
hope this helps ;)
Step-by-step explanation:
to find the slope (m) use the slope formula
m= y2-y1 / x2-x1
*plug in your points*
m= 4-2 / 3- -2 note here the <u>3- -2</u> changes to <u>3+2</u>
solve for m
m= 2/ 5
slope= 2/5
1 mile = 5280 feet
45 x 5280 = 237,600 feet per hour
