Bumek [7]3 years ago
8 0

Answer:

(-1,-2)

Step-by-step explanation:

Let's bring back to memory vertex formula for parabolas.

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

Where (h,k) is the vertex.

In f(x)=2(x+1)^{2}-2

The vertex is (-1,-2)

Solve each quadratic equation by factoring with grouping. 5v2 – 18v = -9
djyliett [7]

Answer:

v = 3 , 3/5

Step-by-step explanation:

5 {v}^{2}  - 18v + 9 = 0 \\ 5 {v}^{2}  - 3v - 15v + 9 = 0 \\ v(5v - 3) - 3(5v - 3) = 0 \\ (5v - 3)(v - 3) = 0 \\ v = 3 \\ v =  \frac{3}{5}

PLZZ HELP!! WILL MARK BRAINLIEST PLZZ!!!
grandymaker [24]

Answer:

see below

Step-by-step explanation:  7  1  16   33

  y  = x²   translated t the point (3, 2)         y = 0 when x = 0

  y =  (x - 3)²    moves the function three units to the right     y = 0 when x = -3

  y  = (x-3)² + 2  moves the function up 2 units      y = 2 when x = -3

  y = (x-3)² + 2

  y = x² - 6x + 9 + 2

  y = x² - 6x +11

graph the equations x²,  (x-3)² + 2,  and x² - 6x + 11   to verify (I did)

if polygon MAST with coordinates M(-3,-1), A(-3,2),S (-1,3) and t (1,1) is reflected across x=-3, then which of the following co
Nookie1986 [14]

Let 'a' be the point and 'A' be the reflection of point 'a' through line x= -3

we know, (a+A)/2 (mid point of line aA) should lie on line x= -3

so by using this, we calculate vertices of reflected shape of MAST, we get

(-3,-1), (-3,2),(-5,3) and (-7,1)

Find the total surface area of the net.​
Elanso [62]

Answer:

87.8 square meters

Step-by-step explanation:

First of all, find the area of the three recthangles.They are all 9m long and 3m wide. 9*3 is 27, and since there are three of them, 27*3 is 81.

To find the area of the two triangles, you could do 3*2.6. Normally, you would halve the values because they are triangles but since there's two of them it cancels out.

3*2.6 is 7.8, and adding that to the area of the rectangles gets the equation 81+7.8 which comes out to 87.8 square meters.
