A parabola has a minimum value of 0, a y-intercept of 4, and an axis of symmetry at x = -2

1 answer:

3 0

Since the minimum value is 0 and axis of symmetry is -2 this means that the vertex is at -2,0 now with the y intercept of 4. You can now plug the values into Vertex form which will be y=a(x-h)^2+k. a being the shrink or stretch of the parabola, h being the x value of the vertex, and k being the y value of the vertex. with all of that plugged in it should look like y=(x+2)^2. You can check this equation by plugging in 0 as x which should find the y intercept of 4. So it should then look like y=(0+2)^2 -> y=(2)^2 -> y=4

(6y+4) = (3y+37) Find the measurement of angle G in the parallelogram EFGH.

IRINA_888 [86]

Yo sup??

The given figure is a parallelogram therefore opposite angles must be equal

6y+4=3y+37

3y=33

y=11

angle H =3*11+37

=70

angle G=180- angle H. (property of parallelogram)

=180-70

=110

Dida bought a scratch ticket for $2.00. The potential payoffs and probability of those payoffs are shown below.

kakasveta [241]

Answer:

(b) $1.15

Step-by-step explanation:

The expected value is the sum of products of payoff and probability:

$0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05

= $0 +0.25 +0.20 +0.20 +0.50

= $1.15 . . . . expected value of the scratch ticket

I don’t get this question

kvv77 [185]

This is a right triangle and to solve this you must use Pythagorean theorem:

$a^{2} +b^{2} =c^{2}$

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 60

b = x

c = 65

^^^Plug these numbers into the theorem

$60^{2} +x^{2} =65^{2}$

simplify

3600 + $x^{2}$ = 4225

Now bring 3600 to the right side by subtracting 3600 to both sides (what you do on one side you must do to the other). Since 3600 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

3600 - 3600 + $x^{2}$ = 4225 - 3600

0 + $x^{2}$ = 625

$x^{2}$ = 625

To remove the square from x take the square root of both sides to get you...

x = √625

x = 25

(option C)

Hope this helped!
