Answer:

125.6 inches

Step-by-step explanation:

Diameter (d) = 40 inches

circumference (c)

= π * d

= 3.14 * 40

= 125.6 inches

Find the x-intercepts of the parabola with vertex (5,-4) and y-intercept (0,96). Write your answer in this form: (x1,y1),(x2,y2)

lesya692 [45]

Answer:

The x-intercepts are

(x1,y1)=(4,0)

(x2,y2)=(6,0)

Step-by-step explanation:

we know that

The equation of the given parabola is

$(y-k)=a(x-h)^{2}$

we have

the vertex is the point (5,-4)

substitute

$(y+4)=a(x-5)^{2}$

The y-intercept is the point (0,96)

substitute and solve for a

$(96+4)=a(0-5)^{2}$

$100=a(25)$

$a=100/25=4$

The equation of the vertical parabola is equal to

$(y+4)=4(x-5)^{2}$

Find the x-intercepts

Remember that

The x-intercepts are the values of x when the value of y is equal to zero

For y=0

$4=4(x-5)^{2}$

Simplify

$1=(x-5)^{2}$

Rewrite

$(x-5)^{2}=1$

square root both sides

$(x-5)=(+/-)1$

$x=(+/-)1+5$

$x=(+)1+5=6$

$x=(-)1+5=4$

therefore

The x-intercepts are

(x1,y1)=(4,0)

(x2,y2)=(6,0)

Whats the Area? how do i find it? In these specific questions?

just olya [345]

The formula for finding the area of a square is:
${s}^{2}$

The formula for finding the area of a triangle is:
$\frac{1}{2} bh$

So for the square the area would be:
${2x}^{2} \times {2x}^{2} = {4x}^{2}$

The area for the triangle would be:

$\frac{1}{2} {2c}^{3} \times 4c = {4c}^{2}$
