If the slope formula is all you have to do is plug in the points:

= =

or

=

Either way your slope is going to be

= =

or

=

Either way your slope is going to be

Question

Franklin deposits $3500 in an account that earns 3.5% interest compounded annually. What function equation represents the balance of the account after t years?

Solution 1

The formula can taken through the compounded interest formula:

A= P(1+r/n) to the power of n time t.

A= P(1+r/n) to the power of n time t.

PÂ =Â is the initial amount or the principal

rÂ =Â interest rate (annually)

tÂ =Â years or tenor of the deposit

AÂ =Â total amount of money after the tenor

nÂ Â = Â frequency of the compound

Solution 2

I just learned this topic today so I am just telling you now that I could be wrong, as I am still trying to completely grasp it!

Use the formula y=b(1+r)^t to solve....

B= initial amount

R= rate

So what is your initial amount??? The initial amount is 3500, which makes your rate 3.5%. YOU MUST CHANGE YOUR PERCENT TO A DECIMAL! (0.035)

Plug in your work: f(t)3500(1+0.035)

Then REMEMBER TO SIMPLIFY! YOU CAN NOT FORGET THIS STEP, IF THIS IS FROM A QUIZ YOU WILL GET THE ANSWER WRONG IF YOU DO NOT!!! (Trust me, I know. I have to retake my quiz for this :o )

Do 1+0.035 and get 1.035

So, again plug in and I am pretty sure you should get the answer:**f(t)=3500(1.035)^t**

Use the formula y=b(1+r)^t to solve....

B= initial amount

R= rate

Question

What is 1.69 x 10^-5 written in standard form

Solution 1

I believe(and i may be wrong), it's .0000169. forgive me if I'm wrong.

Question

When Louisa rented a moving truck, she agreed to pay $28 per day plus $0.42 per mile. If she kept the truck 3 days and the rental charges (without tax) were $153.72, how many miles did Louisa drive the truck?

Solution 1

166 miles becauseÂ

28*3= 84

153.72-84= 69.72

69.72/0.42= 166

28*3= 84

153.72-84= 69.72

69.72/0.42= 166

Question

In a sale, normal prices are reduced by 20%. The normal price of a coat is reduced by Â£15

Solution 1

75 pounds. If 20 percent is 15 then 100 percent is 5*15

Question

A trapezoid has an area of 20 cm2 and a height z cm. The lengths of the parallel sides are (2z + 3) cm and (6z â€“ 1) cm. Find the height, z, of the trapezoid. In your final answer, include all of the formulas and calculations necessary.

Solution 1

Area of a trapezoid = Â½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.Â

From your information 20 = Â½(2z + 3 + 6z â€“ 1)z = Â½(8z + 2)z = z(4z + 1)Â

Solve 20 = 4zÂ² + z which is 0 = 4zÂ² + z â€“ 20 using the quadratic formulaÂ

From your information 20 = Â½(2z + 3 + 6z â€“ 1)z = Â½(8z + 2)z = z(4z + 1)Â

Solve 20 = 4zÂ² + z which is 0 = 4zÂ² + z â€“ 20 using the quadratic formulaÂ

Question

3.25 as a mixed number in simplest form.

Solution 1

3.25 is can be written by usingÂ 325/100, thisÂ is equal to 13/4 when reduced to the lowest terms.

Therefore 3.25 as a mixed number in simplest form is:Â 31/4

Good luck with your studies, I hope this helps~

Therefore 3.25 as a mixed number in simplest form is:Â 31/4

Good luck with your studies, I hope this helps~

Question

Find the correct value of x and y.

Solution 1

D. x = 13 and y = 10

Question

If a graph of a set has an open circle on 1/2 and an arrow pointing to the right, then which of the following numbers is in the set? Please help :) 3/8
1/2
5/6

Solution 1

According to the question, if you graph this on a number line, it basically means any number that is greater than (arrow points to the right is all numbers greater than).

Open circle means that is **not **included.

So we are looking for the option that is **greater than** .

If we divide the choices and make them decimal numbers, it is very easy to see which is the correct answer.

Clearly, is **greater than** . So third answer choice is correct.

**ANSWER:**

Solution 2

5/6 would be the best answer beside the other 2 choices that you have

Question

How to check if an equation is always, sometimes, or never true

Solution 1

When you get the answer, for example you got x=3. And you think its not correct. You can always do a check. Replace the number with the given variable. And if you got both sides same then your answer is correct. For example after doing a check you got 5=5. Then you are right. And if you got 2=4 then you are wrong.
