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

Answer:

[tex]x= 15[/tex]

Step-by-step explanation:

Francisca's mistake was that when she had an equation [tex]5 = \frac{1}{3} x[/tex] instead of dividing both sides by  [tex]\frac{1}{3}[/tex]  she substracted  [tex]\frac{1}{3}[/tex]  from both sides. So the correct way would be...

[tex]5 = \frac{1}{3} x\\\\(5)(3) = (\frac{1}{3} x )(3)[/tex]

[tex]15 = x[/tex]

Answer:

  a) (-2, 0), (0, 0), (1, 0), (3, 0)

  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:

so, i am pretty sure all this is saying is move the plot nine units down the y axis. so you'd plot (5, 7).

Answer:

  yes

Step-by-step explanation:

The side lengths of the triangle are 5, 12, and 5+8 = 13. We can check to see if they satisfy the Pythagorean theorem, which would indicate a right triangle.

  5² + 12² = 25 +144 = 169 = 13²

These sides do satisfy the relationship between sides for a right triangle, so angle A is a right angle. That is the case when segment AB is a tangent to the circle.

  Yes, AB is a tangent.

Answer:

y = -3x + 5

Step-by-step explanation:

Find the graph attached

The standard form of calculating the equation of a line is expressed as;

y = mx+c

m is the slope

c is the intercept

Using the coordinate points (0, 5) and (1, 2)

m = 2-5/1-0

m = -3/1

m = -3

Get the intercept

Substitute m = -3 and (0,5) into y = mx+c

5 = -3(0) + c

5 = c

c = 5

Get the required equation

Recall that y = mx+c

Substitute the gotten values

y = -3x + 5

Answer:

After he cuts the blocks, the volume is one eight of the original.

Step-by-step explanation:

Volume of a rectangular prism:

The volume of a rectangular prism with dimensions abc is given by:

[tex]V = abc[/tex]

Danny cute the block so that each side is 1/2 it's original length. How do the volumes of the ice block compare?

This means that:

[tex]a = \frac{a}{2}, b = \frac{b}{2}, c = \frac{c}{2}[/tex]

So

[tex]V_c = \frac{a}{2}*\frac{b}{2}*\frac{c}{2} = \frac{abc}{2^3} = \frac{abc}{8} = \frac{V}{8}[/tex]

After he cuts the blocks, the volume is one eight of the original.

$275 a week is better buy

Step-by-step explanation:

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:

y=10+5x

Step-by-step explanation:

Have a great day

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:

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
