how is the translation of a figure on a grid different from a reflection of a figure?
Answer:
This means that on the coordinate plane, the coordinates for the vertices of the figure will change. To graph a translation, perform the same change for each point. ... In a reflection, the figure flips across a line to make a mirror image of itself.

A zoo collected data on the diving times of turtles. Based on the data, the regression line is j = 0.010 + 2.515x, where x is the time of the dive, in minutes. Based on the regression equation, what is the predicted dive depth in meters at 150 seconds? Give your answer to three decimal places. meter(s)
Answer:
6.298 meters
Step-by-step explanation:
Here, we are told that x is the time of the dive in minutes.
We simply first need to convert 150 seconds to minutes before substitution into the regression formula;
Kindly recall that 60 seconds = 1 minute
So 150 seconds will be 150/60 = 2.5 minutes
We now proceed to substitute into;
j = 0.010 + 2.515(x)
i = 0.010 + 2.515(2.5)
j = 0.010 + 6.2875
j = 6.2975 which go 3 decimal places is 6.298 meters
Using the regression model given, substitution the value of x = 2.5 minutes into the equation, the dive depth obtained ls 6.2975 meters.
Given the regression model :
y = 0.010 + 2.515xx = time of the dive ; y = dive depthConverting, x to minutes :
150 seconds = (150 ÷ 60) = 2.5 minutes
The dive depth, y after 150 seconds, can be obtained by substituting the value x = 2.5 into the equation :
y = 0.010 + 2.515(2.5)
y = 0.010 + 6.2875
y = 6.2975
There, the dive depth after 150 seconds will be 6.2975 meters

find the compound interest
on Rs 4000 for 30 months at 10% per annum
Answer:
Rs. 1076.23
Step-by-step explanation:
The compound interest is given by the formula;
A=P(1+r/n )^nt
where
A= amount at the elapse of the period
P= principal amount = Rs=4000
r=rate of interest=10% =0.1
n=number of times the interest is applied per time period= 1
t=number of time periods elapsed = 30 months = 30/12 = 2.5 years
Applying the formula;
A=P(1+r/n )^nt
A=4000( 1+ 0.1/1)^1*2.5
A=4000(1.1)^2.5
A=4000 * 1.2691
A=Rs. 5076.24
Compound interest will be : 5076.24-4000 = Rs. 1076.23
A stem and leaf plot shows the number of kilometers walked for charity. The plot is titled 'Kilometers Walked for Charity.' The numbers 12, 13, 14, 15, 16, and 17 are in a vertical column to the left of a vertical line. · On the same line as 12 but on the right of the vertical line are the numbers 3, 3, 6, 7, 9, and 9. · On the same line as 13 but on the right of the vertical line are the numbers 1, 1, 4, 5, and 5. · On the same line as 14 but on the right of the vertical line are the numbers 0, 0, 2, 3, 3, 8, 8, and 9. · On the same line as 15 but on the right of the vertical line are the numbers 2, 2, 2, 2, 2, 3, 5, 5, and 7. · On the same line as 16 but on the right of the vertical line are the numbers 4, 5, 5, 9, and 9. · On the same line as 17 but on the right of the vertical line are the numbers 3 and 5. The key to the stem and leaf plot identifies that 12 vertical line 3 means 12.3. a. Describe how to find the range of the data set. b. Find the range.
Answer:
For part A: Range is difference between the highest value and lowest value of the data set.
For part B: Range is 5.2
Step-by-step explanation:
For part A:
Range of a data set is difference between the highest value and lowest value of the data set.
For part B:
From stem and leaf and it's key ,we can write our data set as
12.3,12.3,12.612.7,12.9,12.9,13.1,13.1,13.4,13.5,13.5,14.0,14.0,14.2,14.3,14.3,14.8,14.8,14.9,15.2,15.2,15.2,15.2,15.2,15.3,15.5,15.5,15.7,16.4,16.5,16.5,16.9, 16.9, 17.3,17.5.
Lowest value of data set = 12.3
Highest value of the data set =17.5
So, range = highest value- lowest value= 17.5-12.3 =5.2

What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
What is the function?The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that value of x determines what value of y will be. This relationship can be expressed as follows: y = f (x)
Given the equation as:
(2x + 2)/y = 4w + 2
To determine the value of x
Multiply by y both sides
y × (2x + 2)/y = (4w + 2) × y
2x + 2 = 4wy + 2y
Subtract 2 from both sides
2x + 2 - 2 = 4wy + 2y - 2
2x = 4wy + 2y - 2
Divide by 2 both sides
x = (4wy + 2y - 2)/2
x = 4wy/2 + 2y/2 - 2/2
x = 2yw + y - 1
Hence, the value of x is 2yw + y - 1.
