Answer:

Step-by-step explanation:

Answer:

h(7+h)

Step-by-step explanation:

You would need to factor the h out of ([tex]7h+h^{2}[/tex])

Answer:

2.12 seconds

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 15t + 40[/tex]

Required

Determine how long the ball hits the ground

When the ball hits the ground means that [tex]h(t) = 0[/tex]

So, we have that:

[tex]h(t) = -16t^2 + 15t + 40[/tex] becomes

[tex]0 = -16t^2 + 15t + 40[/tex]

Reorder

[tex]-16t^2 + 15t + 40 = 0[/tex]

Multiply through by -1

[tex]16t^2 - 15t - 40 = 0[/tex]

Solve using quadratic:

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 16[/tex] [tex]b = -15[/tex] [tex]c = -40[/tex]

So, we have:

[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex] becomes

[tex]t = \frac{-(-15)\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]

[tex]t = \frac{15\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]

[tex]t = \frac{15\±\sqrt{225 +2560}}{32}[/tex]

[tex]t = \frac{15\±\sqrt{2785}}{32}[/tex]

[tex]t = \frac{15\±52.77}{32}[/tex]

Split:

[tex]t = \frac{15+52.77}{32}[/tex] or [tex]t = \frac{15-52.77}{32}[/tex]

[tex]t = \frac{67.77}{32}[/tex] or [tex]t = \frac{-37.77}{32}[/tex]

[tex]t = 2.12[/tex] or [tex]t = -1.18[/tex]

But time can't be negative

So:

[tex]t = 2.12[/tex]

Hence, time to hit the ground is 2.12 seconds

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

Given data

AT&T’s plan

monthly charge= $19.99

additional charge per minute= $0.35

let the number of minutes be x

let the total charges be

y=0.35x+19.99----------1

Verizon’s plan

monthly charge= $34.99

additional charge per minute= $0.3

let the number of minutes be x

let the total charges be

y=0.3x+34.99----------2

Step two:

equating the two equations above we have

0.35x+19.99=0.3x+34.99

collect like terms

0.35x-0.3x=34.99-19.99

0.05x=15

divide both sides by 0.05

x=15/0.05

x=300

For the two plans to cost the same, it will take 300 minutes

Answer:

300 Minutes

Step-by-step explanation:

Answer:

50 son las veses que me pasie, y el 15 son otras actividades que realice

Step-by-step explanation:

La r en ese lugar esta multiplicando al 50

Answer:

.50 means cost per ride and 15 ticket cost

Step-by-step explanation:

say there are 4 ride you want to go on, lets substitute r, rides, with 4

.50(4) + 15

.50 times 4 is 2

so now we have 2 + 15

2 + 15 = 17

so you have spent $17 at the carnival.

Answer:(3,0) , (-2,0)

Step-by-step explanation:To find the x-intercept, substitute in  0 for y and solve for x

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex]f(x) = {x}^{2} - x - 6 [/tex]

[tex]f(x) = (x - 3)(x + 2)[/tex]

[tex]0 = (x - 3)(x + 2)[/tex]

_________________________________

Hint :

[tex]a \times b = 0[/tex]

[tex]a = 0 \: \: \: or \: \: \: b = 0[/tex]

_________________________________

Thus ;

[tex] x - 3 = 0[/tex]

Add sides 3

[tex]x - 3 + 3 = 0 + 3[/tex]

[tex]x = 3[/tex]

Or

[tex]x + 2 = 0[/tex]

Subtract sides 2

[tex]x + 2 - 2 = 0 - 2[/tex]

[tex]x = - 2[/tex]

Thus the x-intercepts are (( - 2 )) and (( 3 )) .

Parallel slope = 2

This is because the original line has slope 2. Parallel lines have equal slopes.

--------------------------

Perpendicular slope = -1/2

The original slope 2 or 2/1 turns into -1/2 after flipping the fraction and the sign. Note the original slope and perpendicular slope multiply to -1. This is true for any pair of perpendicular lines where neither line is vertical.

Answer:

the slope of  the parallel line is 2x

the slope of line perpendicular is -1/2

Answer:

a. is equal.

Step-by-step explanation:

18+18 is 36 and 1+1 is 2. the other questions are not equal.

Hope this helps!

Answer

18/36 = 1/2

13/5 > 7/10

3/5 > 5/9

3/8 < 10/16

Answer:

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1 , thus

y = x + c ← is the partial equation

To find c substitute (1, 0) into the partial equation

0 = 1 + c ⇒ c = 0 - 1 = - 1

y = x - 1 ← equation of line

Answer:

the answer is D because i asked SIRI and BIXBI and they both said the same answers

Step-by-step explanation:

Answer:

Step-by-step explanation:

a. RG=36 since RG=2(RT)

b.

4x+12=10x-15 Since RG and HI are equivalent

12=6x-15 Subtract 4x from both sides

27=6x Add 15 to both sides

4.5=x Divide by 6 on both sides

to double check:

4(4.5)+12=30

10(4.5)-15= 30

so x=4.5

Answer:

the answer is probably 3/5 since its the starting one so it will be how t started

Step-by-step explanation:

Answer:3:5

Step-by-step explanation:well when you divide 6/10 it equals 3/5.when you divide 9/15 it equals 3/5 and so on.

Answer:

It's 99. 7% 95% and 68% for std dev respectively

Give brainliest thanks

Answer:

Because angle 5 and angle 6 equal each other, it would mean that 4 and 7 equal each other. The sum of angles 4 and 5 is 180 because they are on the same line, intersected by another line. This means that they are supplementary angles. Since angles 5 and 6 equal each other, the other part of the the supplementary angle on both sides must equal each other. For example, if angles 5 and 6 equaled 60 degrees, the counterparts on the supplementary angle on both sides would have to be 120 to get to final sum of 180. This shows how angle 4 and 7 have to equal each other if 5 and 6 also equal other. Hope this helped! If its still confusing leave a comment and ill explain it in a different way. Good luck!

Answer:

Step-by-step explanation:

x + 7 ≤ -9 subtract 7 from both sides

x≤-16  this is your answer

If you're plotting it will be (-∞,-16]

Answer:

Step-by-step explanation:

For this equation, all it is asking is to replace the unknown value with a number that completes the equation. However, the number must make the equation valid. Here is a few examples that could be a valid solution to this problem:

1. -55 + 7 < -9

(you don't need to solve this equation to tell that it's less than negative nine.)

2. 22 + (-98) + 7 < -9

(this is more complicated, but you can still tell that the sum is less than negative nine.)

So, basicly all that you have to do is replace the missing value with a number that gives the eqquation a sum less than negative nine. Hope this helped!!! :)
