The correct answers are C and D, please explain why!!!

Answer:

Yes, they are both equal.

Step-by-step explanation:

This is because in both cases, you are subtracting, -7 + -2 = -9. -7 - 2 = -9.

The slope is 3, or 3/1

Step-by-step explanation:

To find the slope, you have to count the rise over run. 3 over 1. The best way to find this, is to go up each unit until you see that the line touches an exact point. Once you find that, go over.

Answer:

7 1/2

Step-by-step explanation:

Let's add the whole numbers first, 3 + 4 = 7

Then, we add the fraction, and since the denominator is the same, there's no need for a change, so we just add the top. 1/8 + 3/8 is 4/8, which can be simplified to 1/2

so answer is 7 1/2

Answer:

a) The domain is 0 < t < 3

The range is 0 < s < 30

b) The x-intercept are the times at the start and return of the ball to the ground

The y-intercept, is the starting height of the ball = 0

c) The axis of symmetry is the line t = 1.5, and the maximum function is the value of the height at the vertex of the parabola, they represent the turning point of the function

d) The rate of change of the function is therefore given by the derivative of function which is;

ds/dt  = d(14.715×t - 1/2×9.81×t²)dt = 14.714 - 9.81×t which is the velocity of the ball at time t

∴ ds/dt = 14.714 - 9.81×t

Which is the velocity of the ball at time t

Step-by-step explanation:

The duration the soccer ball was in the air = 3 s

The maximum height reached by the soccer ball = 30 ft.

Considering the vertical motion of the ball, we have;

v = u - gt

s = u·t + 1/2·g·t²

v² = u² - 2×g×s

Where;

v = The final velocity of the ball = 0 m/s

u = The initial velocity of the ball

g = The acceleration due to gravity = 9.81 m/s²

s = The height the ball reaches = 30 ft

Given that the time to maximum height = Half the total time it was in the air, we have;

v = u - gt

v = 0 at maximum height

u = gt = 9.81 × 3/2 = 14.715 m/s

The vertical velocity = 14.715 m/s

Therefore, we have;

s ≈ 14.715×t - 1/2×9.81×t²

a) The domain is 0 < t < 3

The range is 0 < s < 30

b) The x and y-intercept are;

x-intercept, s = 0, gives;

0 ≈ 14.715×t - 1/2×9.81×t²

From which we have, t = 0 or t = 3, which are the times at the start and return of the ball to the ground

The x-intercept are the times at the start and return of the ball to the ground

The y-intercept, t = 0, gives;

s = 14.715×t - 1/2×9.81×t² = 14.715×0 - 1/2×9.81×0 = 0

Therefore, at the time t = 0 the ball is lying on the ground, height = 0

∴ The y-intercept, is the starting height of the ball = 0

c) The axis of symmetry is the line t = 1.5, and the maximum function is the value of the height at the vertex of the parabola

They represent the turning point of the function

d) The rate of change of the function is therefore given by the derivative of function which is;

ds/dt  = d(14.715×t - 1/2×9.81×t²)dt = 14.714 - 9.81×t

∴ ds/dt = 14.714 - 9.81×t

Which is the velocity of the ball at time t.

Answer:

[tex]x<-5\text{ or } x>1[/tex]

Step-by-step explanation:

We have:

[tex](x+5)(x-1)[/tex]

And we want to find the value of x such that the expression is positive. So, we can write this as the following inequality:

[tex](x+5)(x-1)>0[/tex]

Solve for the inequality. First, we can solve for the zeros like a normal quadratic. So, pretend the inequality is with an equal sign:

[tex](x+5)(x-1)=0[/tex]

Zero Product Property:

[tex]x+5=0\text{ or } x-1=0[/tex]

On the left, subtract 5.

On the right, add 1.

So, our zeros are:

[tex]x=-5, 1[/tex]

Since our inequality is a greater than, our answer is an "or" inequality with our answer being all the values to the left of our lesser zero and all the values to the right of our greater zero.

So, our solution is:

[tex]x<-5\text{ or } x>1[/tex]

And we're done!

Answer:

The regions where (x+5) (x-1) >0 is x< -5  or x>1

Step-by-step explanation:

(x+5) (x-1) >0

First find the zeros

(x+5) =0    x-1 =0

x= -5      x=1

We then have to check the regions

x< -5              -5 <x<1                  x>1

First x< -5

(x+5) (x-1)

X+5 will be negative  ( x-1) will be negative

(-) * (-) = +  so the values will be positive

Then     -5 <x<1      

X+5  will be positive   ( x-1) will be negative

( +) * (-)  will be negative

First x>1

(x+5) (x-1)

X+5 will be positive  ( x-1) will be positive

(+) * (+) = +  so the values will be positive

The regions where (x+5) (x-1) >0 is x< -5  or x>1

Answer:

12th Customer

Step-by-step explanation:

We have to find the lcm (lowest common multiple) of the number.

We do that by taking their multiples. Watch down below

3 x 1 = 3                4 x 1 = 4

3 x 2 = 6               4 x 2 = 8

3 x 3 = 9               4 x 3 = 12

3 x 4 = 12

See how they both have a 12 as their first lcm.

So the 12th customer gets both items.

Glad to help!

Answer: {10, 13, 16, 19, 22, 25}

Step-by-step explanation:

Cab ride cost for first mile = $10

Additional mile cost = $3

Therefore, the following cab cost for different miles are analysed:

Cab ride cost for first mile = $10

Cab ride cost for second mile = $10 + $3 = $13

Cab ride cost for third mile = $10 + $3 + $3 = $16

Cab ride cost for fourth mile = $10 + $3 + $3 + $3 = $19

Cab ride cost for fifth mile = $10 + $3 + $3 + $3 + $3 = $22

Cab ride cost for sixth mile = $10 + $3 + $3 + $3 + $3 + $3= $25

Therefore, th domain of P(C) will be equal to {10, 13, 16, 19, 22, 25}

Answer: B) {10, 13, 16, 19, 22, 25}

The y-value we solved for is 2.

Step-by-step explanation:

The equation they give you, all you need to do is plug in the x-value they give you.

f(x) the y-value in (x, y)

it will be on that bold, vertical line on the graph

2=3x-7

add 7 to both sides

9=3x

divide both sides by 3

Answer:

20165

Step-by-step explanation:

Given:

Length/height (h) of cylindrical test tube = 152 mm

Radius of cylindrical test tube = 6.5 mm

Volume = [tex] \pi r^2h [/tex]

Required:

Volume of cylinder to nearest whole number

Solution:

The volume is given as [tex] V = \pi r^2h [/tex]

Take π as 3.14 and plug the values of r and h into the volume formula.

[tex] V = 3.14*6.5^2*152 [/tex]

[tex] V = 3.14*6.5*152 = 20165.08 [/tex]

Volume of the test tube = 20165 mm³ (nearest whole number)

Answer:

Because the sides BO and MA are marked with one line through the middle, which means those sides are congruent, angle A and Angle O are marked with one line, the angles are congruent, and angles W and N are marked with two lines, which means they are congruent. Therefore the triangles are congruent
