Answer:
(x, y ) → (x - 2, y - 5 )
Step-by-step explanation:
A shift of 2 units left is equivalent to subtracting 2 from the x- coordinate.
A shift of 5 units down is equivalent to subtracting 5 from the y- coordinate.
Thus transformation rule is
(x, y ) → (x - 2, y - 5 )

Line segment AC is given by A (-3,6) and B (6,9). Find the coordinates of point B such that AB:BC is 2:1 Please help now
Answer:
(0, 7)
Step-by-step explanation:
Using the midpoint formula expressed as;
M (X, Y )= [(ax1+bx2/a+b), (ay1+by2/a+b)]
where a and b are the ratios
Given
a = 2
b = 1
x1 = -3
y1 = 6
x2 = 6
y2 = 9
Get the coordinate of B
Get X;
X = ax1+bx2/a+b
X = 2(-3)+1(6)/2+1
X = -6+6/3
X = 0/3
X = 0
Get Y;
Y = ay1+by2/a+b
Y = 2(6)+1(9)/2+1
Y = 12+9/3
Y = 21/3
Y = 7
Hence the coordinate of B is (0, 7)
The circumference of a circle is 13π m. What is the area, in square meters? Express your answer in terms of π π.
Answer:
13×(22/7)whole square
Answer:
42.25π
Step-by-step explanation:
The circumference is the diameter times pi.
This means that 13π/π=13 (the diameter)
The radius is diameter/2, so it is 13/2 which is 6.5
The area is the radius squared times pi
6.5^2 = 42.25
42.25π is the area

x g(x)
0 −5
1 3
2 11

Which sentence compares the two functions' maximum values the most effectively?
(a)The maximum value is the same for both functions.
(b) f(x) has a greater maximum value than g(x).
(c) The greatest value of g(x) is bigger than that of f(x).
(d) The maximum values cannot be determined.
The statement that best compares the maximum value of the two functions is g(x) has a greater maximum value than f(x) that is Option (c).
The maximum value is the point at which a function reaches its peak is known as its maximum value.
To compare both functions.
Take function f(x)= [tex]-2x^{2} +9[/tex]
Differentiate the function f(x)
f'(x) = -4x
Take f'(x) as 0
-4x = 0
x = 0
Substitute x = 0 in f(x)
f(0) = [tex]-2(0)^{2} +9[/tex]
f(0) = 9
This means that the greater value of function f(x) is 9.
From the table of function g(x), the maximum is 11.
11 is greater than 9
Therefore, The greater value of g(x) is bigger than that of f(x).

Kyra was at soccer practice. she blocked 55% of the goals that were kicked at her during a team drill. ashley scored two of the 18 goals that were made during the drill. how many total kicks were attempted
Answer-
Total kicks that were attempted = 40
Explanation
Goals blocked by Kyra = 55%;
Goals which could not be blocked by Kyra = 100 - 55 = 45%
Goals made during team drill = 18
Let total kicks attempted be 'n';
Therefore;
(18/n) × 100 % = 45 %
18/n = 45/100;
n = 1800/45;
n = 40
The time period "percentage" is derived from the Latin per centum, which means "hundred" or "with the aid of the hundred".[5][6] The sign for "percentage" evolved via gradual contraction of the Italian term in line with cento, which means "for 100". The "according to" turned into regularly abbreviated as "p."—subsequently disappeared completely. The "cento" was reduced in size to two circles separated through a horizontal line, from which the present day "%" image is derived.
In mathematics, a percentage (from Latin: in line with centum, "by a hundred") is quite a number or ratio expressed as a fraction of 100. it's miles often denoted using the percentage signal, "%",[1] although the abbreviations "pct.", "pct" and sometimes "pc" also are used.[2] A percentage is a dimensionless number (natural wide variety); it has no unit of size.

After 4 years, $3,006 deposited in a savings account with simple interest had grown to a total of $3,967.92. What was the interest rate?
Answer:
So interest rate is 8% per annum
Step-by-step explanation:
Principal amount = $3,006
Amount at end = $3,967.92
Time = 4yrs
interest money = ($3967.92 - $3006)
also equal to = 4 * (x/100) * $3,006
Where x is the interest rate per annum
So, 4 * (x/100) * $3,006 = ($3967.92 - $3006)
x = 8%
So interest rate is 8% per annum
Use a sample n = 500, = 0.90, and a 95% confidence level to construct a confidence interval estimate of the population proportion, p.
0.887 < p < 0.913
0.878 < p < 0.922
0.874 < p < 0.926
0.817 < p < 0.983
Answer:
0.874 < p <0.926
Step-by-step explanation:
The population proportion lies in the interval 0.8738 < p < 0.9262 with 95% confidence.
What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.
Given, A sample having n = 500, p = 0.90, and we have to construct a 95% confidence interval.
We know the confidence interval for a population proportion is,
CI = [tex]P \pm Z_\frac{\alpha}{2}\sqrt{\frac{P(1 - P)}{n}}[/tex].
CI = 0.9 ± 1.96×{√(0.9×0.1)/500}.
CI = 0.9 ± 1.96×√(0.09/500).
CI = 0.9 ± 1.96×0.0134.
CI = 0.9 ± 0.0262.
Therefore, 0.9 - 0.0262 < p < 0.9 + 0.0262.
0.8738 < p < 0.9262.

Miguel ran 3.8 miles on Monday, 3.9 miles on Tuesday, 4.2 miles on Wednesday and 4.4 miles on Thursday. How many miles should he run on Friday to have an average of 4 miles per day
Answer:
Step-by-step explanation:
Solutions
Solution: Using a table
A B C D E F
Number of Minutes 150 15 7.5 30 45 60
Number of Miles 20 2 1 4 6 8
The values in column B were found by dividing both values in column A by 10. The values in column C were found by dividing both values in column B by 2. The other columns contain multiples of the values in column B.
If we look in column E, we can see that it would take her 45 minutes to run 6 miles.
If we look in column B, we can see that she could run 2 miles in 15 minutes.
If we look in column F, we can see that she is running 8 miles every 60 minutes (which is 1 hour), so she is running 8 miles per hour.
If we look in column C, we can see that her pace is 7.5 minutes per mile.
Solution: Finding a unit rate
If we divide 150 by 20, we get the unit rate for the ratio 150 minutes for every 20 miles.
150÷20=7.5
So the runner is running 7.5 minutes per mile. We can multiply this unit rate by the number of miles:
7.5minutesmile×6 miles=45 minutes
Thus it will take her 45 minutes to run 6 miles at this pace.
If it takes her 45 minutes to run 6 miles, it will take her 45÷3=15 minutes to run 6÷3=2 miles at the same pace.
If it takes her 15 minutes to run 2 miles, it will take her 4×15=60 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).
The average of five consecutive numbers is 38. What is the smallest
number?
Answer:36
Step-by-step explanation:
The required first and smallest term of consecutive terms is 38.
Given that,
The average of five consecutive numbers is 38. The smallest number to be determined.
The average of the values is the ratio of the total sum of values to the number of values.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
The average of five consecutive numbers is 38.
Let the middle value is a,
Series of 5 number can be given as = (a -2n) , (a-n) , a , (a+n) , (a+2n).
n = 5
Average = ( a-2n +a -n + a +a+n+ a+2n)/5
38 = 5a/5
a = 38
Now smallest and first term (n = 1) = a - 2n
= 38 - 2(1)
= 36
Thus, the required first and smallest term of consecutive terms is 38.
