Question 7 of 17
The following figures show the first two steps of a proof of the Pythagorean
theorem. Which of the following statements about this proof is false?
A. The areas of the figures in step 1 and step 2 are equal.
B. Rotating the triangles does not change their areas.
C. The area of the figure in step 1 is (a + b)2.
D. The triangles created in step 2 have the same area.
Answers
Answer:
C
Step-by-step explanation:
(a+b)^2 = (a+b) (a-b)
which isn't a^2 +b^2

Work out length AB.
Answers
Answer:
23.41cm
Step-by-step explanation:
Using Pythagoras theorem
a²+b² = c²
Where a and b are sides of the triangle and c is the Hypotenuse.
If we substitute the values
B= 8 cm
A= 22 cm
22²+8² = c²
484 + 64= c²
√548 = c
C= 23.41
Hence, length AB is 23.41cm

If you want to bowl six games which ally is better show work
Answers
Answer:
Pinz
Step-by-step explanation:
So to set up the equation for Lanez:
y = 3.5 + 4.25x
Next we compare the prices for both overall by plugging 6 games in as x:
Lanez:
y = 3.5 + 4.25(6)
y = 3.5 + 25.5
y = 29
Pinz:
y = 3.75 + 4(6)
y = 3.75 + 24
y = 27.75
29>27.75
Lanez is more expensive with it costing $29 for a night as opposed to the $27.75 one would pay to play at Pinz.

I need the equation for the answer 4a = 32
Answers
To find it, you just divide 32 by 4.
Answer:
a = 8
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other.
Divide 4 from both sides of the equation:
(4a)/4 = (32)/4
a = 32/4
a = 8
8 is your answer for a.

Mean =
Median =
Mode =
Answers
Answer:
Mean: 83.571428571429
Median: 85
Mode: 70
Step-by-step explanation:
The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.
The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.
The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.
Answer:
Median 85
Mode 70
Mean 83.571 rounded = 83.6

Write an equation in slope intercept form for the line with slope 2/5 and y- intercept -1
Answers
Answer:
y =(2/5)x - 1
Step-by-step explanation:
Slope intercept form: y = mx + b
m is slope and b is y-intercept
y =(2/5)x - 1
Answer: y = 2/5x - 1
Step-by-step explanation:
b = y1 - m • x1
-1 = -1 -(2/5) • (0)
= -1
y = mx + b
y = 2/5x - 1

Describe the differences between the graphs, tables, equations, and verbal descriptions of the Linear and Nonlinear functions.
Answers
Answer: 1. The graph of a linear function shows a constant rate of change. A nonlinear function does not have a constant rate of change. So, its graph is not a line. Does the table represent a linear or nonlinear function?While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value). ... is a linear equation but does not describe a function. 2. An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in maths when you do not know the exact number in a calculation. 3. As we stated earlier, nonlinear functions are functions that are not linear functions. Therefore, they have the opposite properties of a linear function. The graph of a linear function is a line. Thus, the graph of a nonlinear function is not a line.
