Review my example on how to find the rate of change for a given set of data. Let (x, y) = (11, 12) and (x', y') = (15, 16). The formula to find the rate of change for the two order pairs is: (y' - y) / (x' - x) = rate of change, so (16 - 12) / (15 - 11) = 4/4 = 1, therefore, the rate of change is 1 *
I would have labeled the points as
(x1,y1) = (11,12)
(x2,y2) = (15,16)
then used the formula
m = (y2-y1)/(x2-x1)
However, your idea works as well. I don't see any errors with your steps. Nice work.
A rectangular picture measures 6 inches by 9 inches. If a copy machine makes each of the two dimensions 113 larger, by what is the percent of increase in the area of the picture
Answer:
27.7% larger
Step-by-step explanation:
6 x 113% = 6.78
9 x 113% = 10.17
Old Area = 9 x 6 = 54 sq in
New Area = 6.78 x 10.17 = 68.95
(New - Old) ÷ Old = .277 = 27.7%

Can anyone help with number 9 please
Answer:
A) 55
Step-by-step explanation:
angle 3 is an exterior angle. to find the interior angle of the triangle, subtract angle 3 from 180
180 - 110 = 70
all the angles in a triangle add up to 180.
since angles 1 and 2 are the same, you can call them x.
70 + 2x = 180
70 - 70 + 2x = 180 - 70
2x = 180 - 70
2x = 110
2x/2 = 110/2
x = 110/2
x = 55
Answer:
A.55
Step-by-step explanation:
The angle that is not numbered =70 because it is the supplementary angles of angle 3. if that is 70 a triangle add to 180 then 180-70=110. and 1 and 2 and equal so 110/2 =55

The moon forms a right triangle with the Earth and the Sun during one of its phases, as shown below: A right angle triangle is shown with the Earth at the right angle. The acute angle between the line joining the Earth and the S The moon is, on average 238,900 miles from the Earth and the Sun is roughly 93,000,000 miles from the Earth. What is the measure of angle x? Round to the nearest hundredth. Note. This is a very small angle.
Answer:
0.15
Step-by-step explanation:
Using trigonometry :
Tanθ = opposite / Adjacent
Opposite = distance between earth and sun = 238,900
Adjacent = distance between earth and moon = 93,000,000
Tanx = 238900 / 93000000
Tanx = 0.0025688
x = tan^-1 (0.0025688)
= 0.1471820°

Answer:
562000
Step-by-step explanation:
commission=commission rate multiplied with selling price
suppose selling price as x
14050=2.5% . x
14050=(2.5/100) . x
14050 . 100= 2.5 . x
x = 1405000/2.5

Consider the polynomial function
g(x) = -x^4 + 2x^3 + 5x^2 – 1.
What is the end behavior of the graph of g ?
Answer: as x > infinity, g(x)> - infinity and as x> - infinity, g(x)> - infinity
Step-by-step explanation:
Left and right ends of the given poynomial function will fall downwards (towards negative infinity).
End behavior of a polynomial: If a polynomial function is f(x) = ax⁴ + bx³ + cx² + dx + eLeading coefficient → a
Degree of the polynomial = 4
If the degree is even and leading coefficient is negative (-), left end and right ends fall downwards.Given in the question,
Poynomial function → g(x) = -x⁴ + 2x³ + 5x² - 1
Degree of the polynomial = 4 (even)
Leading coefficient = -1 (negative)
Therefore, left end of the graph will fall downwards (towards negative infinity) and the right end of the graph will fall downward (towards negative infinity).

13. The area A of a square is the length of a side / squared.
1
Answer:
Area = a²
Step-by-step explanation:
For a square, all 4 sides are equal. If a be the side of a square and A be its area. Then, the area of a square is given by :
Area = side²
or
Area = a²
Hence, the area of a square is square of the length of its side.
Jericho wants to start saving to
purchase a house. His goal is to save $92,400. If he deposits $56,000 into an account that pays 2.92% interest compounded daily, approximately how long will it take for his money to grow to the desired amount? Round your answer to the nearest tenth of a year.
a) 19.3 years
b) 21.7 years
c) 15.4 years
d) 17.2 years
Answer:
its B
Step-by-step explanation:
If he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that,
Principal(P) = $56,000
Rate(R) = 2.92%
Time(T) = x years
Interest(I)=?
The amount to be collected to save the money is,
=$92,400 - $56,000
=$36,400
Interest = $36,400
The formula for the simple interest is,
I=(P×R×T)/100
Substitute the given value as
[tex]\rm 36400=\frac{\left(56000\times \:2.92T\right)}{100} \\\\ \frac{\left(56000\times \:2.92T\right)}{100}=36400 \\\\ \frac{100\times \:56000\times \:2.92T}{100}=36400\times \:100 \\\\ 163520T=3640000 \\\\ T=\frac{1625}{73} \\\\ T=21.7 \ years[/tex]
Thus, if he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.

James is earning money to buy a bicycle for $100. For each dollar James earns, his mother gives him $1. So far he has earned $14 mowing lawns and $7 wash cars. How much more must James earn in order to but the bike??
Answer:
James needs to earn 78 more dollars.
Step-by-step explanation:
If you add up all of the money James has earned, (1 + 7 + 14), it equals 22. If you subtract 22 from 100, it equals 78. Therefore James needs to earn 78 more dollars.
Answer:
$58
Step-by-step explanation:
$14*2=$28 as her mum gives another dollar for each dollar he earns
$7*2=$14 as her mum gives another dollar for each dollar he earns
then 28 + 14 = 42
100 - 42=$58
