You need to invest $3000 at the 5% interest rate and invest $5000 the 6% interest rate to get a total annual interest of $450
Answer:
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 3, - 1), thus
y = a(x + 3)² - 1
To find a substitute (4, 0) into the equation
0 = 49a - 1 ( add 1 to both sides )
49a = 1 ( divide both sides by 49 )
a =
y = (x + 3)² - 1
coefficient of the x² term is
Answer:
I think it's A, either that or D. But i'm pretty sure it's A.
Step-by-step explanation:
Subtract 15 - 4.5 = 10.5 10.5 divided by 2.5 equals 4.2, which equals 4 1 /5.
Answer:
-x aka -1
Step-by-step explanation:
x1 y1 x2 y2
9 -2 4 3
m= y2 - y1/x2 - x1
m = 3 + 2/4 - 9
(The "-" sign turned positive because it is negative times negative)
5/-5
Simplify: 5/-5 = -1 = -x
The slope of this line is -x
B. The angle of elevation is always the angle above the horizontal. The measures of the angles can always vary.
