b 292.5 ft2
c 1,296.0 ft2
d 270.0 ft2

Answer:

1. -18,-7,-4,3,16

2. -39,-24,-12,20,24

3. -64,-57,-32,0,9

4. -24,-14,-8,-3,-1

Step-by-step explanation:

Negative numbers are always least.

Step-by-step explanation:

1

3 x2+52x=1440

Step 2: Subtract 1440 from both sides.

1

3 x2+52x−1440=1440−1440

3 x2+52x−1440=0

For this equation: a=0.3333333333333333, b=52, c=-1440

0.333333x2+52x+−1440=0

Step 3: Use quadratic formula with a=0.3333333333333333, b=52, c=-1440.

x=

x=

−(52)±√(52)2−4(0.333333)(−1440)

2(0.333333)

x=

0.6666666666666666

x=24,−180

Answer:

x=24,−180

Answer:

x = 9

Step-by-step explanation:

( 17x + 7 )° = ( 13x + 3 )° + 40°

17x + 7 = 13x + 3 + 40

17x - 13x = 43 - 7

4x = 36

x = 9

Answer:

y = x - 4

Step-by-step explanation:

The equation is just y = x shifted down 4 units, so it's y = x - 4. If you have to use all of the symbols, you can write "y = x * 1 - 4 + 0". Otherwise, use the one under "Answer" as it is shorter

Answer:

Step-by-step explanation:

you find slope (y1-y2)/(x1-x2) = (0-1)/(4-5) = -1/-1= 1

then you take a point (4,0)

y-0 = 1(x-4)

Answer:

7 Hour

Step-by-step explanation:

Divide 660 by 12 to get the unit rate.

660 divided by 12 equals 55.

Hence, in 1 hour, Goran drives 55 miles. Next, divide 385 by 55 to get 7.

Therefore,Goran 7 hours to drive 385 miles.

Answer:

Hello, There!

First we have to find Out How fast Goran can go in one hour and If we dived by 660 ÷ 12 = 55

Now We know that Goran Drove [tex]55[/tex] Miles in 1 hour

Since We figured out How fast Goran can go in one miles we can add/multiply  to get your final Answer

We can add like this 55, 110, 165,  220, 275, 330, 385

Now we Can Stop because the Question says "Goran drove 660 miles in 12 hours.At the same rate, how long would it take him to drive 385 miles"

And Counting the times we Added we Have the Answer 7

Therefore, It took Goran 7 hours Drive 385 Miles

Answer:

hmmm did you try 14?

Answer:

Using a calculator, if you typed in 517 divided by 7, you'd get 73.8571. You could also express 517/7 as a mixed fraction: 73 6/7.

Answer:

-6

Step-by-step explanation:

Take the x out for -2

f(-2) is equivalent to x=-2

f(x) = 5x + 4

1. f(-2)=5(-2)+4

2. f(-2)= -10+4

3. -6

Answer:

<R=56 degrees; <Q=62 degrees; <S=62 degrees

Step-by-step explanation:

5x+12=4x+22 (This is because the two angles are congruent to each other.)

x+12=22

x=10

Now, plug it in.

5(10)+12=50+12=62 degrees

62(2)=124 degrees (This is because the two angles are congruent and equal)

180-124=56 degrees

To Find :-

Solution :-

According to Question ,

When y = 14 and x = 4 ,

When x = 9 ,

A parabola is a mirror-symmetrical U-shape.

From the question, we have:

[tex]\mathbf{Vertex: (h,k) = (80,10)}[/tex]

[tex]\mathbf{Origin: (x,y) = (0,0)}[/tex]

The equation of a parabola is:

[tex]\mathbf{y = a(x - h)^2 + k}[/tex]

Substitute the values of origin and vertex in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]

[tex]\mathbf{0 = a(0 - 80)^2 + 10}[/tex]

[tex]\mathbf{0 = a(- 80)^2 + 10}[/tex]

[tex]\mathbf{0 = 6400a + 10}[/tex]

Collect like terms

[tex]\mathbf{6400a =- 10}[/tex]

Solve for a

[tex]\mathbf{a =- \frac{1}{640}}[/tex]

Substitute the values of a and the vertex in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]

[tex]\mathbf{y = -\frac{1}{640}(x - 80)^2 + 10}[/tex]

The focus of a parabola is:

[tex]\mathbf{Focus = (h, \frac{k+1}{4a})}[/tex]

Substitute the values of a and the vertex in [tex]\mathbf{Focus = (h, \frac{k+1}{4a})}[/tex]

[tex]\mathbf{Focus = (80, \frac{10+1}{4 \times -\frac{1}{640}})}[/tex]

[tex]\mathbf{Focus = (80, -\frac{11}{\frac{1}{160}})}[/tex]

[tex]\mathbf{Focus = (80, -11\times 160)}[/tex]

[tex]\mathbf{Focus = (80, -1760)}[/tex]

The equation of the directrix is:

[tex]\mathbf{y = -a}[/tex]

So, we have:

[tex]\mathbf{y = \frac{1}{640}}[/tex] ----- the directrix

The axis of symmetry is:

[tex]\mathbf{x = -\frac{b}{2a}}[/tex]

We have:

[tex]\mathbf{y = -\frac{1}{640}(x - 80)^2 + 10}[/tex]

Expand

[tex]\mathbf{y = -\frac{1}{640}(x^2 -160x + 6400) +10}[/tex]

Expand

[tex]\mathbf{y = -\frac{1}{640}x^2 +\frac{1}{4}x - 10 +10}[/tex]

[tex]\mathbf{y = -\frac{1}{640}x^2 +\frac{1}{4}x }[/tex]

A quadratic function is represented as:

[tex]\mathbf{y = ax^2 + bx + c}[/tex]

So, we have:

[tex]\mathbf{a = -\frac{1}{640}}[/tex]

[tex]\mathbf{b = \frac{1}{4}}[/tex]

Recall that:

[tex]\mathbf{x = -\frac{b}{2a}}[/tex]

So, we have:

[tex]\mathbf{x = -\frac{1/4}{2 \times -1/640}}[/tex]

[tex]\mathbf{x = \frac{1/4}{1/320}}[/tex]

This gives

[tex]\mathbf{x = \frac{320}{4}}[/tex]

[tex]\mathbf{x = 80}[/tex]

Hence, the axis of the symmetry of parabola is: [tex]\mathbf{x = 80}[/tex]
