Find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6).
Sergio [31]
Hello,

Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3

y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)

Answer B.

Asking again because last time I didnt get an actual answer. What is the surface area of this composite figure?
Katyanochek1 [597]

Answer:

644 cm^2

Step-by-step explanation:

10*7*2+12*7*2+12*10=140+168+120=428

10*12-3*3=111

428+111=539

8*3*4+3*3=96+9=105

539+105=644

A(x-y) + b (x-y) factorize​
Andre45 [30]

Answer:Given expression : a(x-y)-b(x-y)

Now, (x-y) is common in both terms.

First factor is (x-y).

∴a(x−y)−b(x−y)=(x−y)(a−b)

If you are reading this hope you have a wonderful day and may your dreams come true!

Find the x-value for point C such that AC and BC from a 2:3 ratio.
Galina-37 [17]

Given:

Point C divides AB such that AC:BC=2:3.

To find:

The x-value for point C.

Solution:

Section formula: If a point divide a line segment in m:n, then

Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)

Form the given graph it is clear that the endpoints of the line segment AB are A(-3,5) and B(3,0).

Point C divides AB such that AC:BC=2:3. Using section formula, the coordinates of point C are

C=\left(\dfrac{2(3)+3(-3)}{2+3},\dfrac{2(0)+3(5)}{2+3}\right)

C=\left(\dfrac{6-9}{5},\dfrac{0+15}{5}\right)

C=\left(\dfrac{-3}{5},\dfrac{15}{5}\right)

C=\left(-0.6,3\right)

The x-value of C is -0.6.

Therefore, the correct option is B.
