Trevor pays $125 in fees each semester plus $650 per college course.
Last semester Trevor paid $2,725.
Which function represents Trevor’s bill?

A.f(x) = 125x + 650
B.f(x) = 650x + 125
C.f(x) = 775x
D.f(x) = 525x

Answers

Answer 1
The correct answer is Choice B.

This is an example of an equation in slope-intercept form, y = mx + b.

The slope, m, is the amount of increase each course, or 650.
The y-intercept, b, is the starting fees that are paid.

Put them together and you have: y = 650x + 125 of Choice B.

You deposit $1500 in an account that pays 7% annual interest. Find the balance after 2 years when the interest is compounded daily.

The balance after 2 years when the interest is compounded daily is

$1,725.39.

What is Compound Interest?

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest.

Given:

P= $1500

R= 7%

T = 2 years

Now, using

A = P[tex](1 + r/n)^{nt[/tex]

A = 1,500.00[tex](1 + 0.07/365)^{(365)(2)[/tex]

A = 1,500.00[tex](1 + 0.00019178082191781)^{(730)[/tex]

A = $1,725.39

Hence, the balance is $1,725.39.

The explicit rule for a sequence is an=9(−5)n−1 .



What is recursive rule for the sequence?




an=5−(an−1),a1=9

an=−9(an−1),a1=5

an=9−(an−1),a1=5

an=−5(an−1),a1=9

Answers

Explicit rule is a(n) = 9*(-5)^(n-1)

The recursive rule is a(n) = -5*a(n-1); a(1) = 9

The first term is 9. Each new term is found by multiplying the previous term by -5

We can see this when we raise -5 to a whole number power. Eg: 9(-5)^3 = 9*(-5)*(-5)*(-5)

Answer: Choice D

Answer:

Option 4th is correct.

[tex]a_n = -5 \cdot a_{n-1}[/tex] , [tex]a_1 = 9[/tex]

Step-by-step explanation

The explicit sequence of the geometric sequence is given by:

[tex]a_n = a_1r^{n-1}[/tex]              ....[1]

where,

r is the common ratio

n is the number of terms

[tex]a_1[/tex] is the first term

As per the statement:

The explicit rule for a sequence is:

[tex]a_n=9(-5)^{n-1}[/tex]

On comparing [1] we have;

[tex]a_1 = 9[/tex] and r=  -5

Recursive formula for the geometric sequence is given by:

[tex]a_n = r \cdot a_{n-1}[/tex]  for [tex]n\geq 2[/tex]

Substitute the given values we have;

[tex]a_n = -5 \cdot a_{n-1}[/tex]

Therefore, the recursive rule for the sequence is, [tex]a_n = -5 \cdot a_{n-1}[/tex] , [tex]a_1 = 9[/tex]

Im learning Polynomials and we are learning the strategy grouping, can anyone please explain how to group polynomials and maybe give an example :) greatly appreciated

Answers

Grouping is when you have to terms that are the same inside the parenthesis and a different or same number outside the parenthesis and then the one inside the parenthesis u are going to group them not combined them and write them once and the numbers inside the parenthesis group them together by adding them and put parenthesis between them

Ex
5(4x+1)10(4x+1)
(5+10)(4x+1)
Grouping can mean different things in different contexts. In simple cases, polynomials are written in such a way that all you need to do is add parentheses to make groups. Usually we are interested in doing this so we can factor or simlify the result.

Example
  x^2 +2x +3x +6
  (x^2 +2x) +(3x +6) . . . . parentheses added to group pairs of terms
  x(x +2) +3(x +2) . . . . . . common factor pulled from the terms of each group
  (x +3)(x +2) . . . . . . . . . common factor removed to give factored result

What is an expression?

A term is a single mathematical phrase. It might consist of only one variable—a letter—one number—positive or negative—or several variables multiplied but never added or subtracted. A number is placed in front of some nouns that have variables. Coefficients are numbers that come before phrases.

To simplify each expression, we combine like terms:

Expression 1:

12x + 3 − 4x + 7 = (12x − 4x) + (3 + 7)

12x + 3 − 4x + 7 = 8x + 10

Expression 2:

8 − 7x − 13 + 2x = (−7x + 2x) + (8 − 13) = −5x − 5

Expression 3:

−3x − 18 + 5x − 2 = (−3x + 5x) + (−18 − 2) = 2x − 20.

Therefore, the simplified expressions are:

12x + 3 − 4x + 7 = 8x + 10

8 − 7x − 13 + 2x = −5x − 5

Philip is going on a 400040004000-kilometer road trip with three friends. The car consumes 666 liters of gas per 100100100 kilometers, and gas costs \$1.50$1.50dollar sign, 1, point, 50 per liter. If Philip and his friends want to split the cost of gas evenly, how much should they each pay?

Answers

Let us calculate how much gas he will need for the trip. Since he needs 6 liters for 100 miles, he will need x for 4000 miles. Gas is proportional to mileage. Solving for x, x=4000/100 *6=240
In total, this will cost 240*1.5=360$. He has 3 friends, so they are 4 in total. Everyone will have to pay 360/4=90$
Let's calculate how much gas would car consume during the trip.
First, we will calculate how much it consumes per kilometer:
[tex]g_{ckm}=6/100=0.06\frac{l}{km}[/tex]
The total consumption for the whole trip would be:
[tex]g_t=L\cdot g_{ckm}=0.06\cdot 4000=240 l[/tex]
To get the total cost of the gas we multiply the total gas consumed by its cost:
[tex]C_t=g_t\cdot1.5=360\$[/tex]
So, each passenger must pay $90.

when the solutions to each of the two equations below are graphed in the xy coordinate plane, the graphs of the solutions intersect at two places. Write the y-coordinate of the points of intersection in the boxes below in order from smallest to largest. y=2x and y=x^2-3

Answers

The points of intersection are at (3, 6) and (-1, -2).

Since both of these equations have y isolated, we can set them equal to each other:

2x=x²-3

We want all of the variables on one side, so subtract 2x:
2x-2x = x²-3-2x
0=x²-3-2x

Write the quadratic in standard form:
0=x²-2x-3

This is easily factorable, as there are factors of -3 that will sum to -2.  -3(1)=-3 and -3+1=-2:
0=(x-3)(x+1)

Using the zero product property we know that either x-3=0 or x+1=0; therefore x=3 or x=-1.

Substituting this into the first equation (it is simpler):
y=2(3) = 6
y=2(-1)=-2

Suppose a population of 175 crayfish doubles in size every month. the function f(x) = 175(2x) gives the population after x months. how many crayfish will there be after 1 year?

Answers

The first thing we will do in this case is to rewrite the expression correctly.
 We have then:
 f (x) = 175 * (2 ^ x)
 Then, you should know that 1 year contains 12 months.
 So we have that for x = 12:
 f (12) = 175 * (2 ^ 12)
 f (12) = 716800

 there will be 716800 crayfishes after 1 year

The answer to the question is C because 249.99 + (0.0625 x 249.99) = $265.61
So C

The  Price for Desk after tax is $265.614.

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Ben bought a desk for $249.99.

Tax rate = 6.25%

So, the price for desk after tax

= 249.99 + 249.99 x 6.25%

= 249.99 + 249.99 x 0.0625

= 249.99 +15.62

= $265.614

Hence, the Price for Desk after tax is $265.614.

What would be the side length of the smallest square plate on which a 40-cm chopstick can fit along a diagonal without any overhang? (Correct answer will get reward)

Answers

The side length of the smallest square plate required to fit a 40-cm chopstick along its diagonal without any overhang is approximately 28.284 cm.

To find the side length of the smallest square plate in which a 40-cm chopstick can fit along a diagonal without any overhang, we can use the Pythagorean theorem. The diagonal of a square is the hypotenuse of a right-angled triangle formed by two sides of the square. Since the sides of the square are equal, if one side is s, then the diagonal d can be calculated using the equation d = s√2, where √2 is the square root of 2 (approximately 1.4142).

Therefore, to fit a 40-cm chopstick along the diagonal:

Let d = 40 cm.

Use the equation s√2 = 40 cm to find s, the side of the square.

s = 40 cm / √2.

s ≈ 28.284 cm when rounded to three decimal places.

So, the side length of the smallest square plate on which a 40-cm chopstick can fit along a diagonal without any overhang is approximately 28.284 cm.

Cl is the reducing agent and F is the oxidizing agent. 3 consecutive odd numbers whose sum is -63 What change do you have to make to the graph of f(x) = 7x in order to graph the function g(x) = 7x+10?
