Answer: [tex]a_{10}[/tex] = -33
Step-by-step explanation:
-6, -9, -12, -15
The common difference is -3
d = common difference
Arithmetic sequence formula:
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1) d
[tex]a_{10}[/tex] = -6 + (10 - 1) -3
[tex]a_{10}[/tex] = -6 + 9 × -3
[tex]a_{10}[/tex] = -6 - 27
[tex]a_{10}[/tex] = -33
Answer:
its -30
Step-by-step explanation:
because -15-15=-30

What is the domain and range of a function?Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x is defined.
Given, A set of domains and ranges in roaster form the points(x, y) are
are at (- 3, 3), (0, 0), and (3, 3).
Now we know the domain is the set of all x values.
∴ domain {- 3, 0, 3}.

Answer:
14.9
if you need it
side a is 24.04867
9514 1404 393
Answer:
c ≈ 14.9 cm
Step-by-step explanation:
I personally like to use a proportion that has the unknown in the numerator. The angle opposite c is ...
C = 180° -150° -12° = 18°
Then the law of sines tells us ...
c/sin(C) = b/sin(B)
c = sin(C)·b/sin(B) = sin(18°)/sin(12°)(10 cm)
c ≈ 14.9 cm

Answer:
B
Step-by-step explanation:
Find the slope, or rate of change, from the graph.
answer please correct answers
Answer:
3/2
Step-by-step explanation:
slope is rise over run
or y change divided by x change
to find the slope you need to find points on the graph that meet exact points on the graph
i see (0,0) and (4,6)
to find slope without graph it would be (y2-y1)/(x2-x1)
in this case (6-0)/(4-0)
=6/4
=3/2
=1 1/2
with graph you can count that it goes up 3 squares while moving two squares to the right

A store used to sell an MP3 for $72which is 50% more than the wholesale cost. At a special holiday sale, the price of the MP3 was 20% less than the wholesale cost. What was the special sale price of the MP3?
Answer:
$115.2
Step-by-step explanation:
Step one:
Given data
A store used to sell an MP3 for $72 and we are told that this 50% of the wholesale price.
Therefore the wholesale price is
72*2= $144
Required:
The special sales cost at 20% discount
Step two:
We are told that the special sale is at a 20% discount on the wholesale
= 20/100*144
=0.2*144
=$28.8
Therefore the special sales price is
= 144-28.8
=$115.2

You are testing two scales for accuracy by weighing two different objects. Use the drop-down menus to complete the statements about the scales' accuracy.
Answer:
Because the object on scale 1 weighs more than the object on scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and scale 2 was 3 pounds off, so scale 1 was 10% off and scale 2 was 12% off.
The object on scale 1 weighs 100 pounds and the object on scale 2 weighs 25 pounds so the object on scale 1 weighs more than scale 2.
Scale 1 error margin: Scale 2 error margin:
= Actual weight - measured weight = 25 - 22
= 100 - 90 = 3 pounds
= 10 pounds
Scale 1 error percentage: Scale 2 error percentage:
= Error margin/ Actual weight = 3/25
= 10/100 = 12%
= 10%
Scale 1 object has less percent error.
Answer:
Fill in Blanks in Caps and Numbers are in ()
Because the object on scale 1 weighs (MORE) than the object on scale 2, each pound of error results in a (LESSER) percent error. Scale 1 was (10) pounds off and scale 2 was (3) pounds off, so scale 1 was (10)% off and scale 2 was (12)% off

Answer:
33, 27285Step-by-step explanation:
The price difference is found by subtracting Emma's price from DeShawn's price. Each price is the product of the number of square feet and the price per square foot.
The number of square feet is already given in the answer form, so you only need to fill in the per square foot prices. Those are found in the table. Both the window name and the window area give clues as to which is the right price to choose.
The expression is (4² × 33) - (3² × 27).
__
For the second fill-in, you need to actually do this arithmetic. For many calculators, you can enter this expression directly.
DeShawn paid $285 more for his window than Emma.
It takes Ann 8 hours to travel a
distance of 480 miles. At this rate,
how many miles does she travel in
13 hours?
780 miles
60 miles
97 miles
1260 miles
Answer:
d = 780
Step-by-step explanation:
Remark
You can do this with a proportion which will save you figuring out the rate. I'll do it both ways
Proportion
480/8 = x / 13 Cross Multiply
8*x = 13*480
8x = 6240
x = 780 miles
======================
Remark
Often times we like questions to follow a formula. Here's the formula method.
Formula
d = r * t
Givens
t = 8 hours
d = 480miles
r = ?
480 = r * 8
480 / 8 = r
r = 60
Second part
r = 60 miles per hour
t = 13 hours
d = ?
d = 60*13
d = 780 miles

Write the quadratic equation whose roots are 1 and -3, and whose leading coefficient is 1.
(Use the letter x to represent the variable.).
Step-by-step explanation:
Factor Theorem:
"If a is a root of a polynomial, (x - a) is a zero of the polynomial."
Therefore by Factor Theorem,
we have (x - 1)(x + 3) = x² + 2x - 3.
which equation represents a line that passes through the point ( 6,-3 ) and is parallel to the graph of y = 3x + 1
Answer:
Equation of a line that passes through the point ( 6,-3 ) and is parallel to the graph of y = 3x + 1 is [tex]\mathbf{y=3x-21}[/tex]
Step-by-step explanation:
We need to write equation of a line that passes through the point ( 6,-3 ) and is parallel to the graph of y = 3x + 1
The equation will be in slope-intercept form i.e [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Finding Slope
Since the lines are parallel to each other, their slopes will be equal.
Slope of given line: y = 3x + 1 is 3 (Compare it with general equation [tex]y=mx+b[/tex] we get m = 3)
So, slope of required line is: m=3
Finding y-intercept
Using the point (6,-3) and slope m = 3 we can find y-intercept by using the formula:
[tex]y=mx+b\\-3=3(6)+b\\-3=18+b\\b=-3-18\\b=-21[/tex]
So, we get y-intercept: b= -21
Equation of required line
The equation of required line having slope m=3 and y-intercept b = -21 is:[tex]y=mx+b\\y=3x-21[/tex]
So, equation of a line that passes through the point ( 6,-3 ) and is parallel to the graph of y = 3x + 1 is [tex]\mathbf{y=3x-21}[/tex]

The average athlete is able to begin activity 90 days after having a knee operation. The standard deviation is 20 days. Sixty-eight percent of athletes are able to participate within how many days? Round to the nearest day.
Answer:
99
Step-by-step explanation:
The mean = 90 days
standard deviation = 20 days
P(Z < z) = 68 %
getting the value of z-score from the standard normal table of 0.68
z = 0.47
P(Z < 0.47) = 0.47 * 20 + 90 = 99

How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Median
Arrange your numbers in numerical order.
Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

In a paint factory, an old conveyer line has filled 12 barrels of paint, and is filling more at a rate of 4 barrels per minute. A worker just switched on a newer line that can fill 10 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How long will that take? How many barrels will each line have filled?
Answer:
Take 2 minutesEach line would have filled 20 barrelsStep-by-step explanation:
First line is filling at 4 barrels a minute and has already filled 12
Second line is filling at 10 barrels a minute.
Assume the time taken to be equal is x:
12 + 4x = 10x
12 = 10x - 4x
6x = 12
x = 12/6
x = 2 minutes
Each barrel would have filled:
= 10x
= 10 * 2
= 20 barrels

Colin was thinking of a number. Colin doubles it, then adds 9 to get an answer of 95.4. What
was the original number?
Answer:
43.2
Step-by-step explanation:
Set up an equation to model the situation;
2x + 9 = 95.4
"x" represents the unknown number. 2x is present because the number is double. 9 is added because the problem says that Colin added 9. This is set equal to 95.4, because the result attained is 95.4.
Solve the equation using inverse operations;
2x + 9 = 95.4
-9 -9
2x = 86.4

x = 43.2
