Answer:

Position of the particle is 20.

Step-by-step explanation:

Position function is integration of velocity function.

Velocity function is integration of acceleration function.

So, let's integrate the given a(t) to get v(t)

If we integrate v(t) then we get s(t)

It is given the values of s(0) =0 and s(1)=20

So, position of the particle is difference of 20, 0. That's 20-0 =20.

Step-by-step explanation:

10 /5 = 2

5/10 = 0.5

The function for the value of the motorcycle after x years are;

y = 8000 - 500x

y = -500x + 8000

A function is a relationship between inputs where each input is related to exactly one output.

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have given that new motorcycle has a value of $8,000. Every year its value decreases by $500.

Now, we have y = amount of the motorcycle

x = number of years

The function for the value of the motorcycle after x years.

y = 8000 - 500x

y = -500x + 8000

Thus,

y = 8000 - 500x

y = -500x + 8000

Answer:-5.8

Explanation:4.5-8.3=-3.8 -3.8-2=5.8

Answer:

i think the answer is 23

Step-by-step explanation:

well the equation says c=45+7n so the total cost is 206 . i subtracted 45 from 206 leaving me with 161 then i divided that by 7 leaving me with 23

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The total cost of n T-shirt is C = 45 + 7n.

The number of T-shirt coach Dell ordered for the team is 23 T-shirts.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Total cost:

C = 45 + 7n

n = number of shirts.

Now,

Dell paid $206.

This means,

206 = 45 + 7n

Subtract 45 on both sides.

206 - 45 = 7n

161 = 7n

Divide both sides by 7.

n = 161/7

n = 23

The number of shirts is 23  if the cost of the paid is $206.

Thus,

The number of T-shirt coach Dell ordered for the team is 23 T-shirts.

Answer:

1. 6.75x or (6.75, 1)

2. He buys 9 sandwiches.

Step-by-step explanation:

For the first one, we know that he pays $6.75 for each sandwich, so if x equals the number of sandwiches, when written out it would be 6.75x

For the second one, we have to divide it up and solve one step at a time, and when we start solving them, we will find the pieces to figure out the other problems. Let's start with how much he paid. We know that he paid $80, but we have to remember that he got change back. So to find out how much he truly paid, we subtract the 19.25 from the 80. When we do this, we get 60.75. Now, to find out how many sandwiches he got, we can use how much he paid for each one. We know that he paid $6.75 for each one, and in total he spent $60.75. So to find out, we can simply divide 6.75 into 60.75, and we get 9. So now we know that he bought 9 sandwiches.

Answer:

Step-by-step explanation:

imagine a graph that you see, the x-axis has to be positive for it to be on the right side of the y-axis so the value of the y axis can be positive or negative and then you substitute for a positive number, in this case, into the x axis and then you would solve for every answer choice to see if it's right or not if it is accurate.

The solution of the subtraction operation is equal to 4.75 .

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS - Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We need to Subtract 0.25 subtracted from 5

We know that 0.25 x 20 = 5

so, the subtraction is;

5 - 0.25 = 4.75

Answer:

x = 28.9

Step-by-step explanation:

tan = [tex]\frac{opposite}{adjacent}[/tex]

⇒ tan 48 = [tex]\frac{26}{x}[/tex]

(tan of 48 is 1.11)

⇒ 1.11 = [tex]\frac{26}{x}[/tex]

multiply 26 on both sides

⇒ 1.11 x 26 = [tex]\frac{26}{x}[/tex] x 26

⇒ 28.86 = x

round to the nearest tenth

⇒ 28.86 = 28.9

Answer:

-7y > 161

7y < -161

y < -23

7y > -161

y > -23

Answer:    0.25 as a decimal

Answer:

0.25

Step-by-step explanation:

You can think of fractions as smaller increments of money.

2/4=0.5

3/4=0.75

Bob has a dollar bill. He uses 1/4 of it to buy a coupon.

Imagine this happening:

1$

Uses 1/4

So... Let's look at what I've given you.

2/4=0.5

3/4=0.75

Well, let's stretch some things a liiiiitle bit.

Bob has a dollar bill blah blah...

We get to 1/4.

Le's make that 2/4.

2/4 is 0.5

So... By stretching the truth

We can infer that

If we put 1/4 back

(Oh no now the word problem creators are mad at me ;) lol)

Anyways, we can infer that by putting 1/4 back

That since 3/4 is 0.75
