0,0 as center of dilation 1/4 and a =10,6
The new coordinates after the dilation with scale factor 1/4 is
a' = (5/2 , 3/2)
To get the new coordinates when the point is dilated is to multiply the scale factor with the coordinates of the point.
According to the question we have been given that
center of dilation = (0,0)
Scale factor = 1/4
coordinate of the point, a = (10,6)
To get the new coordinates we will multiply the given coordinates by the scale factor that is ,
a' = 1/4*(10,6)
= (10*1/4 , 6*1/4)
a' = (5/2 , 3/2)

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following:
18 Pennies 19 Dimes
16 Nickels 20 Quarters
What is the probability that you reach into the jar and randomly grab a dime and then, without replacement, a penny? Express your answer as a fraction or a decimal number rounded to four decimal places.
The probability of picking a dime and then a penny without replacement is 0.0651.
What is the probability?Probability is used to determine the odds that a random event would happen. The probability the event happens is 1 and the probability that the event does not happen is 0.
The more likely the event is to occur, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
The probability of picking a dime and then a penny without replacement = (number of dimes / total number of coins) x (number of pennies / total number of coins - 1)
(19 / 73) x (18 / 72) = 0.0651

Find the reference angle for -7pi/5
Answer:
When the terminal side is in the first quadrant (angles from 0° to 90°), our reference angle is the same as our given angle. This makes sense, since all the angles in the first quadrant are less than 90°. So, if our given angle is 33°, then its reference angle is also 33°.
When the terminal side is in the second quadrant (angles from 90° to 180°), our reference angle is 180° minus our given angle. So, if our given angle is 110°, then its reference angle is 180° – 110° = 70°.
When the terminal side is in the third quadrant (angles from 180° to 270°), our reference angle is our given angle minus 180°. So, if our given angle is 214°, then its reference angle is 214° – 180° = 34°.
When the terminal side is in the fourth quadrant (angles from 270° to 360°), our reference angle is 360° minus our given angle. So, if our given angle is 332°, then its reference angle is 360° – 332° = 28°.

Estimating percents 19% of 72
Pleas explain how because I don’t understand this
Answer:
13.68
Step-by-step explanation:
72 * 0.19 = 13.68
19% can be converted to 19/100 or .19 to change out of a percentage. .19 is the multiplied by 72 to find 19% of 72.
For example
a fourth of something is the same as 25%.
if you want to find 1/4 of 8 you would multiply 8 by 1/4.
It is a similar concept with percentages.
A medical insurance policy requires Harold to pay the first $550 of her hospital expense. The insurance company will then pay 75% of the remaining expense. Harold estimates the total bill to be about $20,500. Apart from that Harold also had to pay 12% of $450 fee for prescription medications and a $250 late fee if she pays the bill after September 30. How much will Harold's total payment be if he pays on October 2nd?
Harold's total payment is $5,841.50.
What is Harold's total payment?Percentage is the fraction of a quantity that is expressed as a number out of hundred. The sign used to represent percentages is %. Percentages are a measure of frequency.
The total bill Harold would pay is the sum of the first $550, 25% of the remaining bill, 12% of the fee for prescription medications and the late payment fee since she paid after September 30.
Amount of total bill that Harold would pay = (100 - 75)% x (20,500 - 550)
25% x 19,950 = $4,987.50
Amount of the prescription medications Harold pays : 12% x 450 = $54
Total bill - $550 + $4,987.50 + $54 + $250 = $5,841.50

Solve the system of equations.
3x + 48 + 32 = 9
3x+3y +32=3
2x + 4y + 32 = 8
Answer:
It will be (x=1.y=6.z=-6
Answer:
Choice b
(x = 1, y = 6, z = -6)
Step-by-step explanation:
The system of equations is
3x + 4y + 3z = 9 (1)
3x + 3y + 3z = 3 (2)
2x + 4y + 3z = 8 (3)
Subtract (2) from (1) to eliminate the 3x and 3y terms and solve for y
(1) - (2)
==> 3x + 4y + 3z - (3x + 3y +3z) = 9 - 3
==> 3x + 4y + 3z - 3x - 3y - 3z = 6
(3x-3x) + (4y-3y) + (3z-3z) = 6
4y - 3y = 6
y = 6
Subtract (3) from (1) to isolate the x term
(3x - 2x) + (4y-4y) + (3z-3z) = 9 -8
x = 1
Divide equation (2) on both sides by 32 to eliminate the coefficients
Equation (2) ÷ 3
==> (3x + 3y + 3z) / 2 = 3/3
==> x + y + z = 1 (4)
Substitute the values of x and y in Equation (4)
1 + 6 + z = 1
7 + z = 1
Subtract 7 from both sides
==> z = 1-7 = 6
Answer:
(x = 1, y = 6, z = -6)
The cost of a taxi ride, in dollars, is $2 for the first quarter mile plus $0.40 for each quarter mile after that. Jameel cannot
afford to spend more than $20 on a taxi ride.
The equation 2 + 0.4(4m - 1) = 20 can be used to find m, the distance, in miles, that Jameel can travel for $20. What
is the maximum distance?
A) 13.5 miles
B 16.0 miles
C11.5 miles
(D) 14.0 miles
The maximum distance Jameel can travel is 11.5 miles
How to determine the maximum distance?The equation that determines the distance is given as
2 + 0.4(4m - 1) = 20
Subtract 2 from both sides of the equation
So, we have
0.4(4m - 1) = 20 -2
Evaluate the like terms
So, we have
0.4(4m - 1) = 18
Divide both sides by 0.4
So, we have
(4m - 1) = 18/0.4
Evaluate the quotients
So, we have
(4m - 1) = 45
Remove the bracket
So, we have
4m - 1 = 45
Add 1 to both sides of the equation
4m = 46
Divide both sides of the equation by 4
So, we have
x = 11.5
Hence, the maximum distance Jameel can travel is 11.5miles

At its farthest, the earth is about 9.52 * 10 ^ 7 miles from the sun. Light travels from the sun at a speed of around 1.2 * 10 ^ 6 miles per minute. How many minutes does it take for the light to travel from the Sun to the Earth? Show your calculations and write in standard form.
The number of minutes to take for the light to travel from the sun to the earth is 7.93×[tex]10^{1}[/tex] minutes.
The distance between the earth and sun=9.52×[tex]10^{7}[/tex] miles
The speed of the light from sun=1.2×[tex]10^{6}[/tex] miles per minutes
Speed=Distance/Time
Time= Distance/Speed

Time taken for the light to travel from the sun to the earth = The distance between the earth and sun ÷ The speed of the light from sun
Substitute the values in the equation
=9.52×[tex]10^{7}[/tex]÷ 1.2×[tex]10^{6}[/tex]

f-¹(x) =
The function of f(x) = (x+4)³ + 3 is one-to-one then the value of
[tex]f^{-1} (x) = \sqrt[3]{x} - 4[/tex] and,
[tex]f^{-1} (2) = -2.7401[/tex]
The function f(x) = (x+4)³ + 3
Let us assume,
y = (x+4)³ + 3
What is Invertible function?A function is said to be invertible when it has an inverse. It is represented by [tex]f^{-1}[/tex]. Condition for a function to have a well-defined inverse is that it be one-to-one and Onto or simply bijective.
Then,
y = (x+4)³ and y = 3
Therefore the inverse of y = 3 is the line x = 3
We can solve,
y = (x+4)³
The solution of Inverse function,
So,
[tex]\sqrt[3]{y} = x+4[/tex]
We can get,
[tex]x = \sqrt[3]{y} -4[/tex]
So the inverse of y is [tex]\sqrt[3]{x} -4[/tex]
f(x) = (x+4)³
So the inverse of f(x) is [tex]\sqrt[3]{x} -4[/tex]
Therefore, [tex]f^{-1}( x)[/tex] = [tex]\sqrt[3]{x} -4[/tex]
Then f(x) = 2
[tex]f^{-1} (x) = \sqrt[3]{x} - 4[/tex]
We can substitute f(x) = 2
[tex]f^{-1} (2) = \sqrt[3]{2} -4[/tex]
Since, ∛2 = 1.2599
We can substitute this value,
[tex]f^{-1} (2) = 1.2599-4[/tex]
[tex]f^{-1} (2) = -2.7401[/tex]
Therefore,
