Find
y
'
and then find the slope of the tangent line at
(
2
,
225
)
. Round the slope and y-intercept to 3 decimal place.
Answers
To find the slope, you plug in 2 for y’ as it is the x-value of the point.
y’ = 2((2)^2+2(2)+7)(2(2)+2) = 180
Plug in the point and the slope in the point-slope formula
y - y1 = m(x - x1)
y - 225 = 180(x - 2)
Solve for y
y = 180x - 360 + 225
y = 180x - 135

Answers
Answer:
Option 3 (79−3x=12x+19)
Step-by-step explanation:
When replacing x with 4 you will get the answer 67 = 67, which is true! The other three options are not true when replacing x with 4.
Equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.
Given that, the equations that have {4} as its solution set.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
1) Solution of an equation 5 + 2x = 3x + 3 is
3x-2x=5-3
⇒x=2
2) Solution of an equation 7−x=12x is
7−x=12x
⇒12x+x=7
⇒13x=7
⇒x=7/13
3) Solution of an equation 79−3x=12x+19 is
12x+3x=79-19
⇒15x=60
⇒x=4
4) Solution of an equation x²+3=10x−21 is
x²+3=10x−21
⇒ x²-10x+24=0
⇒ x²-6x-4x+24=0
⇒ x(x-6)-4(x-6)=0
⇒ (x-6)(x-4)=0
⇒ x=6 or 4
Therefore, equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

Below is a graph of p, an insect population, w weeks after it was first measured. The population grows exponentially.
Write an approximate domain and range for this situation.
Write an equation relating p and w.
Answers
The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]p = 300 * 3^w[/tex]
From the graph, we have the following ordered pairs
(1,900) and (3,8100)
An exponential function is represented as:
[tex]p = ab^w[/tex]
At the point (1,900), we have:
ab = 900
At the point (3,8100), we have:
ab^3 = 8100
Divide both equations
[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]
Evaluate the quotients
[tex]b^2 = 9[/tex]
Take the square roots of both sides
b = 3
Recall that:
ab = 900
So, we have:
3a = 900
Solve for a
a= 300
Hence, the equation is:
[tex]p = 300 * 3^w[/tex]

A TV has an original price of $499. Find the new price given a 10% increase.
Answers
Have a great day/night
Answer: $548.9
Step-by-step explanation:
To find the next price you have to find 10% of the original price then add it. You can find the increase by dividing 499 by 10 to get 10%.
499 divided by 10 = 49.9
Now add the increase to the original price for your answer!
499 + 49.9 = $548.9

5 is the answer.
Review:What is a cuboid?
A cuboid is a rectangle, but in 3D form.
Do we calculate area or volume in a cuboid?
We calculate the volume for 3D shapes. For 2D shapes, area is used.
If/Then:
Now, if the volume of the cuboid is 24 units³ then:
x × x × y
Now, lets fit all our options to see which one is NOT the dimensions.
Option A:
x × x × 3 = 24 units³
x × x = 12 units³ ✔
This is possible.
Option B:
x × x × 4 = 24 units³
=> x × x = 6 units³ ✔
This is possible.
Option C:
x × x × 5 = 24 units³
=> x × x = 24/5 units³ ❌
This is not possible. This will be our answer.
Option D:
x × x × 6 = 24 units³
=> x × x = 4 units³✔
This is possible.

if all functions are relations, are all relations functions? Explain your answer
Answers
Answer:
No, because some relations are not functions. Relations are equations that begin with x=, and let's say x=5.
This is not a function because if you graph this line, it is vertical, and functions can't share the same x coordinate point (input) with other y coordinate points (output). There must be one output for every input, meaning that this relation is not a function.

The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
2. What is the MAD for company C's data? Show your work.
3. Which company had the greatest mean number of deliveries?
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Answers
Answer:
The means differ by 4 times the MAD.
Step-by-step explanation:
I may be missing something, but this is how I interpret it.
The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.
[tex]14-6=8\\8\div2=4[/tex]
The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.

To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $4 per hour. The chemistry club wants to spend at most $47 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Answers
Answer:
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Step-by-step explanation:
h=hours
19+4h=47
Subtract 19 from both sides of the equation.
4h=28
Divide 4 from both sides of the equation.
h=7
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Hope this helps :)
Answer:
7 hours
Step-by-step explanation:
There is $47 total dollars. The reservation fee is $19 dollars. Subtract the two:
47-19= 28 dollars
Now the per hour fee is 4 dollars an hour. And you have 28 hours. So divide the two to get maximum hours:
