write the factored form for a quadratic equation with x-intercepts of -6 and -2 and the point (-3,-6) is on the parabola

kenny6666 [7]

F(x)=a(x-x1)(x-x2)
F(x)=a(x- - 6)(x- -2)
F(x)=a(x+6)(x+2)
-6=a(-3+6)(-3+2)
-6=a(3)(-1)
-6=-3a
2=a

Equation: f(x)=2(x+6)(x+2)

Point A lies on the circle and has an x-coordinate of 1.

stellarik [79]

Answer:

$\sqrt{(0-y)^{2}+(0-1)^{2}}=2$

Step-by-step explanation:

we know that

In the circle of the figure the radius is equal to 2 units

The distance from the center of the circle (origin) to the point A must be same at the radius

Applying the formula's distance between two points

point A( 1,y) and point (0,0)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$2=\sqrt{(0-y)^{2}+(0-1)^{2}}$

rewrite

$\sqrt{(0-y)^{2}+(0-1)^{2}}=2$

If 2 pounds of strawberries cost $4.50 how much would 3 pounds cost?

AfilCa [17]

we know that

$2$ pounds of strawberries cost $\$4.50$

by proportion

<u>Find the cost of $3$ pounds of strawberries</u>

$\frac{4.50}{2} \frac{\$}{pounds} =\frac{x}{3} \frac{\$}{pounds}\\ \\x=(4.50*3)/2\\ \\x=\$6.75$

therefore

<u>the answer is</u>
