6. You deposit $1000 a year into an account. This account earns 8% interest compounded yearly,(20 points)a) how much will you have after 10 years?b) How much total money did you put in the account.c) How much total interest did you earn?
Compound interest formuae :
A = P ( 1+r/100)^ n or A = P( 1+i)^n or A = P ((1 + i )^n -1 )/i
we will use the highlighted formular due to compounded yearly statement on the question:
where A = Accumulated amount;
P = original amount invested/ (borrowed )
n = number of years
r = interest rate as a percentage
i = r/100
Answer to (a )
A = P ((1 + i )^n -1 )/i
where n = 10; i = 8/100 =0.08 ; P = 1000
A = 1000 ( 1 + (8/100))^10 -1)/ 0. 08
A =1000 ( 14.48)
A =$14486.56
b. 1000 X 10 = $12000
c. you earned interest of $14486 - $12000 = $2486

Brooke decided to ride her bike from her home to visit her friend Adam. Two miles away from home, her bike got a flat tire and she had to walk the remaining four miles to Adam's home. She could repair the tire and had to walk all the way back home. How many more miles did Brooke walk than she rode.
Answer:
8 miles
Step-by-step explanation:
I'm going to assume the question said that she "couldn't" repair the tire and was forced to walk back home, that makes more sense.
With that in mind:
She rode her bike 2 miles.
She walked 4 miles on the way there, and 6 miles on the way back.
You can deduce that it was a 6 mile walk back because of the 2 mile bike ride, then the 4 mile walk that it took to get there.
All in all that rounds out to 10 mile walking, and 2 mile biking. That is 8 miles more walking than biking.

3.1.1 The basic property of operations used in this calculation is the commutative property of multiplication. It states that the order of the factors in a multiplication problem can be rearranged without changing the product. In this case, the numbers 25 and 4 were swapped, resulting in the same product of 100.
3.1.2 The basic property of operations used in this calculation is the additive inverse property. It states that for any number, there exists an additive inverse such that when the number and its additive inverse are added together, the result is zero. In this case, adding 412 and its additive inverse (-412) results in zero.
3.1.3 The basic property of operations used in this calculation is the associative property of addition. It states that the grouping of numbers being added does not affect the sum. In this case, the numbers 25, 37, 20, 5, 30, and 7 were regrouped to facilitate easier mental addition. By grouping 25 and 37, and then grouping 20, 5, 30, and 7, the final sum of 62 is obtained, which is the same as adding all the numbers together in the original order.

The area of a rectangle room is given by the equation x^2+x=12, where w is thewidth if the room. What is the width of the room?
Answer:
w = 3
Step-by-step explanation:
factoring x² + x - 12 you get (x + 4)(x - 3) = 0
x = -4 and x = 3
since you cannot have a negative width, we exclude that value and use the positive value of 3

HELP ASAP!! what is the value of f(-3)
Answer:
f(-3) = 4
Step-by-step explanation:
There are two ways to do it with the information given to you, you can look at the graph or use the equation.
Equation:
Since x = -3, you would put -3 in for x in the first equation which gives 4. It looks like you were on the right track but forgot that it was negative so you ended up adding 3 instead of subtracting. At least that is where I assume the 10 comes from.
Graphical:
Looking at the graph you can also find the value. You want to find the value of y at x = -3, so you look at the spot where x = -3. You will see that there are two "points" there, one open and one closed. The closed circle one means that the graph includes -3 in its x value. The open circle one means the graph contains every number until x=-3.
So to find the y value at x = -3 you want to look at the y value that corresponds to the closed circle of the graph since it is the part that includes x=-3 and you will see that y = 4 at that spot.

Help pleaseeeeeeeeeeeeee
Answer: f(8) = 620.6
Step-by-step explanation:
To solve, you must first use substitution, and replace the x value in the given function, with 8.
\(f(8)=\frac{750}{1 + 74e^{-0.734(8)} }\)
Next you follow PEMDAS to solve the rest of the equation to find f(8).
What is PEMDAS?
PEMDAS is the order of operations for mathematical expressions involving more than one operation.
You solve in the following order
P = ParenthesisE = ExponentsM = MultiplicationD = DivisionA = AdditionS = SubtractionIn this case our next step is deal with the exponents.
And by doing so, you will be multiplying -0.734 by 8
\(f(8)=\frac{750}{1 + 74e^{-5.872} }\)
And typical with exponents we would raise the number or variable given to the power of the exponent.
However we have a continuous number in this case, which is e.
What is e?
e is a mathematical constant approximately equal to 2.71828
We can now use a calculator to find what e (2.71....) is when raise to the exponent -5.872. Which results to 0.002817 (0.0028172332293320237716146943697).
When continuing to use numbers in calculators, don't use the rounded or shortened of the full number. Make sure to use the all of the numbers (given in the calculator) to its full extent to maintain accuracy.
\(f(8)=\frac{750}{1 + 74(0.002817) }\)
Now multiply 74 and 0.002817.... (use the full number to multiply (0.0028172332293320237716146943697)). The product is (0.2084752589705697590994873833578).
\(f(8)=\frac{750}{1 + 0.2084 }\)
Now lets add 1 + 0.2084.... and you get 1.2084
\(f(8)=\frac{750}{1.2084 }\)
Last you need to divide:
and you get that
f(8) = 620.6167
Now lets go back to the question, and we see that is says for you to round your answer to the nearest tenth.
so your final answer is:
f(8) = 620.6

O 35 yds²
The area of a right triangle with a height of 8 yards and a base of 17 yards is 136 square yards.
The area of a right triangle with a height of 8 yards and a base of 17 yards can use the formula for the area of a triangle:
Area = (base x height) / 2
Substituting the given values into the formula get:
Area = (17 x 8) / 2
Area = 136 square yards
The area of the right triangle is 136 yd².
To understand why this formula works can visualize the right triangle as half of a rectangle.
The height of the triangle is one side of the rectangle and the base of the triangle is the adjacent side of the other half of the rectangle.
The area of the rectangle is the product of its height and base is twice the area of the right triangle.
The product of the height and base by 2 to get the area of the right triangle.
