5^2 i want to know what that is.

Answer:

2 m/s

Step-by-step explanation:

Given the graph of the baseball thrown into air.

John throws the baseball into the air from a given height and then the baseball reaches a maximum height and then comes back to ground.

The height of the baseball (in metres) is modeled by the function graph with respect to time.

To find:

The average rate of change of height of the ball from the point the ball is thrown to the maximum height.

Solution:

Here, the average rate of change can be found by dividing the distance between the two points with the change in time.

The starting time is 0 seconds.

The starting height is 3 metres.

The ending time is 2 seconds i.e. at which the ball reaches the maximum height.

The height is 7 metres.

Therefore, the average rate of change is:

[tex]\dfrac{\text{Change in height}}{\text{Change in time}}\\\Rightarrow \dfrac{7-3}{2-0}\\\Rightarrow \dfrac{4}{2}\\\Rightarrow 2\ m/s[/tex]

Answer:

2 meters per second

Answer:

[tex]x = 4[/tex]

Step-by-step explanation:

[tex]AD = BC[/tex]

[tex]8x - 12 = 20[/tex]

[tex]8x = 20 + 12[/tex]

[tex]8x = 32[/tex]

[tex] \frac{8x}{8} = \frac{32}{8} [/tex]

[tex]x = 4[/tex]

to be sure

[tex]8x - 12 { = }^{?} 20[/tex]

[tex]8 \times 4 - 12 { = }^{?} 20[/tex]

[tex]32 - 12 { = }^{?} 20[/tex]

[tex]20 = 20[/tex]

5 + 8 is not equal to 7

Because 5 + 8 = 13

Answer:

Because you add up and count

Step-by-step explanation:

When you take specific number and add it another, that would be adding. first of all you need to say 8 first, because its a bigger number 8+5=13 then you subtract it by 6

8 + 5 - 6= 7

Answer:

0.2709

Step-by-step explanation:

Given that:

Average time between accidents (λ) = 7 weeks

Probability that more than 8weeks pass between accidents

P(x > 8) = 1 - P(x ≤8)

P(x > 8) = 1 - [p(0) + p(1) + p(2) + p(3) + p(4) + p(5) + p(6) + p(7) + p(8)]

To save computation time :

We can use a poisson distribution calculator :

Hence,

P(x > 8) = 1 - P(x ≤8)

P(x ≤8) = 0.72909

P(x > 8) = 1 - 0.72909

P(x > 8) = 0.2709

how can i help also comment me i wanna talk bc im lonely lol

Step-by-step explanation:

The cost of one dog collar and one dog leash are 10.25 dollars and 14.5 dollars respectively

let

the cost of each dog collars = x

the cost of each leashes = y

Therefore,

3x + 2y = 59.75

x + 3y = 53.75

Hence,

3x + 2y = 59.75

3x + 9y = 161.25

7y = 101.5

y = 101.5 / 7

y = 14.5

Therefore,

x + 3y = 53.75

x + 3(14.5) = 53.75

x = 53.75 - 43.5

x = 10.25

Answer:

No

Step-by-step explanation:

This would be more of an opinion and not a fact, but I see it as very unlikely that they will be able to accomplish this goal. Mainly due to human psychology. Most individuals want to be able to physically hold their money as well as being able to physically exchange their money for the goods that they need since physical cash is accepted worldwide. Another main reason is that individual's want to know that their money is theirs and that no bank or corporation can withhold their hard earned cash.

1) 19+i

2) 9-3i

hope this helps bro

Answer:

1. 19

2. 9 + 11i

Step-by-step explanation:

first problem:

first, we rewrite it and remove the parentheses.

12 - 3i + 7 + 3i

then, just remove the opposites and calculate.

19

second problem:

again, we rewrite and remove the parentheses.

12 + 4i - 3 + 7i

then, we calculate and collect like terms.

9 + 11i

Answer:

Simplifying

5x + 0(x + y) + -3y + 14 + -3(y + -1x) = 0

Anything times zero is zero.

5x + 0(x + y) + -3y + 14 + -3(y + -1x) = 0

Reorder the terms:

5x + 0 + -3y + 14 + -3(-1x + y) = 0

5x + 0 + -3y + 14 + (-1x * -3 + y * -3) = 0

5x + 0 + -3y + 14 + (3x + -3y) = 0

Reorder the terms:

0 + 14 + 5x + 3x + -3y + -3y = 0

Combine like terms: 0 + 14 = 14

14 + 5x + 3x + -3y + -3y = 0

Combine like terms: 5x + 3x = 8x

14 + 8x + -3y + -3y = 0

Combine like terms: -3y + -3y = -6y

14 + 8x + -6y = 0

Solving

14 + 8x + -6y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14' to each side of the equation.

14 + 8x + -14 + -6y = 0 + -14

Reorder the terms:

14 + -14 + 8x + -6y = 0 + -14

Combine like terms: 14 + -14 = 0

0 + 8x + -6y = 0 + -14

8x + -6y = 0 + -14

Combine like terms: 0 + -14 = -14

8x + -6y = -14

Add '6y' to each side of the equation.

8x + -6y + 6y = -14 + 6y

Combine like terms: -6y + 6y = 0

8x + 0 = -14 + 6y

8x = -14 + 6y

Divide each side by '8'.

x = -1.75 + 0.75y

Simplifying

x = -1.75 + 0.75y

I'm not sure if the graph or equation answers your question or not sorry if I did it wrong.

Answer: Tables, graphes, and equation are realted because they all have the same information but just in diffrent ways. the advantage of a table is that you can see more information and what other possblities and fill in missing spots. graphes you can fid the equation on it by counting on it.

replace c with 71.50

the third one

25+0.15m=71.8

Answer:

the answer is c. 25 + 0.15m = 71.8

Step-by-step explanation:

25 is the initial fee, or the down payment.

.15 represents the cost of a mile

m represents the number of miles driven

so, 25 + .15m = 71.8 (because $71.80 is the total bill)
