Answer:

Step-by-step explanation:

Remark

Unless you know calculus, the only way to solve this is by completing the square.

Solution

y = 4x^2 + bx - 2

y = 4(x^2 + b/4 ) - 2

y = 4(x^2 + b/4 + (1/2b/4)^2 ) - 2 - 4*(b/8)^2

y = 4(x^2 + b/4 + (b/8)^2 ) -  2 - b^2/16

y = 4(x + b/8)^2 - 2 - b^2/16

Now what you want to happen is to give b/8 a value of 1 so that when x is put in -1 you get 0 for  what is inside the brackets.  

b/8 = 1

b = 8

y = 4(x + 1)^2 - 2 - (8)^2 / 16

y = 4(x + 2)^2 - 2 - 4

y = 4(x + 1)^2 - 6

The vertex is at (-1, - 6)

The axis of symmetry  is x = - 1

Note

This could have been done a lot shorter just by realizing that the number inside the brackets had to be + 1 as in (x + 1). But then you would not have been able to know the minimum value for y which is - 6

i think you should revise the q. it looks incorrect...

all but 3 students said they would NOT vote for a tiger...** if that"s the thing then this answer is correct did it by ratio file is attatched:)

Answer:

15%

Step-by-step explanation:

1. Subtract final value from starting value

65 - 55.25 = 9.75

2. Divide 9.75 by original number

9.75/65 = 0.15

3. Multiply quotient by 100 to get percentage

0.15 x 100 = 15%

Answer:

d ≤ -0.5

Multiply each term by -1

Answer:

x = 53.7 degrees

Step-by-step explanation:

[tex]tan = \frac{opposite}{adjacent}[/tex]

[tex]tan x = \frac{15}{11}[/tex]

tan x = 1.36

tan-1 of 1.36 = 53.7

Answer: what is the question

Step-by-step explanation:

Answer: 17 cm

Step-by-step explanation:

For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:

V = B*H

Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3

Then:

B = 3cm^2

V = 51cm^3

If we replace those in the equation above, we get:

51 cm^3 = (3cm^2)*H

Solving this for H gives:

(51 cm^3)/(3 cm^2) = H = 17 cm

The height of the tubing is 17 cm

Answer:

Distance cover by Alyson = 16 miles

Step-by-step explanation:

Given:

Distance cover together = 39 miles

Assume;

Distance cover by Jeff = a

Distance cover by Alyson = a - 7

Find:

Distance cover by Alyson

Computation:

a + (a - 7) = 39

2a - 7 = 39

2a = 46

a = 23

Distance cover by Alyson = a - 7

Distance cover by Alyson = 23 - 7

Distance cover by Alyson = 16 miles

there are 7 days in a week so total cost for weekly rate will be $275

total cost for per day offers will be $48*7= $336

since$336>$275

Answer:

336 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a right triangle

A of rectangle = length × breadth = 24 × 12 = 288 ft²

A of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 32 - 24 = 8 ft and h = 12 , then

A of Δ = [tex]\frac{1}{2}[/tex] × 8 × 12 = 4 × 12 = 48 ft²

composite area = 288 + 48 = 336 ft²

Answer:

The largest angle is 102

Step-by-step explanation:

2x + 3x + 10 = 180

5x = 170

x = 34

2(34) = 68

3(34) + 10 = 102

  b) (0, 0)

Step-by-step explanation:

a) The graph crosses the x-axis at x = -2, 0, 1, 3. The corresponding (x, y) coordinates are ...

  (-2, 0), (0, 0), (1, 0), (3, 0) . . . . . x-intercepts

__

b) The graph crosses the y-axis at y = 0. The corresponding (x, y) coordinates are ...

  (0, 0) . . . . . y-intercept

Answer:

Not a function

Step-by-step explanation:

x repeats, you have 5 mapped to 1 and 5 mapped to 9 so you have to have a one-to-one relationship with your points if it is a function
