i Just need the graph points
Answer:
Step-by-step explanation:
In the graph, y is the amount of sand in mm^3 and x is time in seconds.
They are directly related as the sands drops at a constant rate of 2.5 cubic millimeters ( mm^3 ) every second.
So y = 2.5x
Input x=0, output is y=0
The first point is (0, 0)
Input x=2, y=2.5*2=5
The second point is (2, 5)
Input x=6, y=2.5*6=15
The third point is (6, 15)
What is the exponential regression equation to best fit the data where the y values were rounded to the nearest integer.
Question 9 options:
y=3(1. 05)^x
y=2. 1(2. 05)^x
y=2. 17(2. 96)^x

You are at a trade show where you are selling baseball cards for $4 a card and buying baseball cards for $6 a card. If you started the day with $200, how much money do you have at the end of the day if you sold c baseball cards and bought b baseball cards?
Answer:
200 +4c -6b
Step-by-step explanation:
Your ending balance is the sum of your beginning balance plus sales, less your purchases. If each sale nets $4, then c sales will increase your balance by 4c. If each purchase costs $6, then b purchases will reduce your balance by 6b.
Your ending balance is ...

Step-by-step explanation:
After four years of college, Erica has to start paying off all her student loans. Her first payment is due at the end of this month. Her bank told her that she has 7 years to pay off all of her loans, and that starting this month, the loans will be compounded monthly at a fixed annual rate of 9.1%. Erica currently has a total of $34,006.00 in student loans. Use the formula for the sum of a finite geometric sequence to determine Erica's approximate monthly payment.
Answer:
Therefore, the approximate monthly payment is $548.85
Step-by-step explanation:
The amount of student loans Erica currently has = $34,006.00
The duration over which Erica is to pay back the loan = 7 years
The annual interest rate for the loan = 9.1%
Therefore, we have the geometric sequence formula is given as follows;
[tex]A_n = P( 1 + r)^n - M \times \left [ \dfrac{(1 + r)^n-1}{r} \right ][/tex]
Where;
M = The monthly payment
P = The initial loan balance = $34,006.00
r = The annual interest rate = 9.1%
n = The number of monthly payment = 7 × 12 = 84
Aₙ = The amount remaining= 0 at the end of the given time for payment
Substituting the values into the above formula, , we get;
[tex]0 = 34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} - M \times \left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ][/tex]
[tex]M = \dfrac{34006 \times \left ( 1 + \dfrac{0.091}{12} \right )^{84} }{\left [ \dfrac{\left (1 + \dfrac{0.091}{12} \right )^{84}-1}{\dfrac{0.091}{12} } \right ]} \approx 548.85[/tex]
Therefore, the approximate monthly payment = $548.85
The first few steps in solving the quadratic equation 8x2 80x = −5 by completing the square are shown. 8x2 80x = −5 8(x2 10x) = −5 8(x2 10x 25) = −5 ______ which number is missing in the last step? −200 −25 25 200
The number is missing in the last step in the quadratic equation is 200. Then the correct option is D.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The quadratic equation is 8x² + 80x = −5
On adding and subtracting 200 on both sides, we have
8x² + 80x + 200 = −5 + 200
8 (x² + 10x + 25) = −5 + 200
Thus, the number is missing in the last step in the quadratic equation is 200. Then the correct option is D.

Answer:
180 units
Step-by-step explanation:
Find the sum of the interior angles of a polygon with 20 sides
Answer:
3240°
Step-by-step explanation:
The sum of the interior angles of a polygon is found by (n-2)(180) where n is the number of sides so (20-2)(180) = (18)(180) = 3240°

The modified expression, x3(2x 5) – 4(2x 5), has two terms with a common factor of.
Answer:
Step-by-step explanation:
You need to use the distributive property to take out the common factor. But that doesn't tell you what the common factor is.
Look inside the brackets. You need to find something that is exactly the same on either side of the minus sign. In this case you have a huge cle about what it is.
2x^5 is it not? I'm assuming that's the correct way to read it.
So that's the answer to your question 2x^5.
The distributive property will tell you that 2x^5 can be taken out, and what is left is

For the linear relation y= 2x + 5, the x-intercept is -2/5
True
False
Answer:
False
Step-by-step explanation:
Every linear equation in two variables can be written as y=mx+c.
Here, for each value of x there is a unique value of y.
Also, x & y are in direct variation.
Hence, xy will always remain constant.
Consequently, the graph will maintain a definite slope making it a straight line.
∴ The given statement is false.
Answer:
False
Step-by-step explanation:
=> y = 2x + 5
=> y - 2x = 5
=> - 2x + y = 5
=> (-2x + y) = 5
=> (-2/5)x + y/5 = 1
=> x/(-5/2) + y/5 = 1, it is in form of x/a + y/b = 1, a is intercept of x.
So, here, x intercept is -5/2.
Method 2;
=> y = 2x + 5
=> y = 2(x + 5/2)
=> y = 2{x - (-5/2)}, says, x intercept is - 5/2 & not - 2/5

You want to test the effects of water aerobics on resting heart rate. You decide to test two different levels of exercise (water aerobics for 30 minutes twice a week and water aerobics for 60 minutes once per week.) You randomly find a group of 60 subjects (30 men and 30 women) for this study. What is an appropriate design for this study? A). Randomized block design B). Completely randomized design C). Matched pairs design
Answer:
The correct option is;
A). Randomized block design
Step-by-step explanation:
In a randomized block design the experimental units or subjects of the experiment are separated into subgroups known as blocks with the property that the the variability (difference) of the parameters within the blocks are lesser than the variability between block, such that the treatment of the research or experiment are assigned differently to each block
The groups can therefore comprise of the following;
Group 1
15 men and 15 women to perform water aerobics for 30 minutes twice a week
Group 2
15 men and 15 women to perform water aerobics for 60 minutes once a week
Therefore, the effect of the experiment will be much less attributed to gender than to the durations of the water aerobic exercise.

To hire a tutor, Abelia will pay $35 per hour plus a materials fee of $10. She will only pay the materials fee one time. The equation c = 10 + 35h can be used to represent this situation where c is the total cost and h is the number of hours Abelia hires the tutor.
Answer:
Yes! C=10+35h is correct!
Step-by-step explanation:
Yes, equation is correct!
$10 is fixed one time fee.$35 is hourly pay.
So, if she needs tutor for 'h' hours, the variable cost is $35h
So, total cost C =10+35h
