An isosceles right angled triangle has two equal sides, and those two equal sides make 90 degrees (right angle) internally. The correct option is A.
What is an isosceles right angled triangle?An isosceles right angled triangle has two equal sides, and those two equal sides make 90 degrees (right angle) internally.
Since the two of the angles of the triangle are equal, therefore, the length on the opposite sides of this angle will be equal to each other. Hence, we can write that the length of the side s will be equal to 4.
Hence, the correct option is A.

A vacuum cleaner costs $140. If the sales tax rate is 6%, what is the amount of sales tax? What is the total cost of the vacuum cleaner with sales tax?
Answers
Step-by-Step Explanation:
Cost of Vacuum Cleaner = $140
Sales Tax Rate = 6%
Sales Tax = 6% of $140
= 6/100 * 140
= 6/10 * 14
= 84/10
= 8.4
Therefore, Sales Tax = $8.4
Total Cost with Sales Tax = Cost of Vacuum Cleaner + Sales Tax
= 140 + 8.4
= 148.4
Therefore, Total Cost = $148.4

Let a = the length. This is unknown.
Let b = the width. This is unknown.
Let c = the diagonal. This is a known value.

20 points please!!! helpp with functions and average rate of change
Answers
Answer:
option C.
Step-by-step explanation:
If we calculate average rate of change of a function over a certain interval, we’re computing the average number of units which the function moves up or down, per unit along on the xx-axis. We might alternatively argue that we’re measuring how much change occurs in our function’s value per unit on the xx-axis.
The equation for average rate of change is -
Δx/Δf =
f(x2) - f(x1) / x2 - x1
Answer:
C k(x)
Step-by-step explanation:
The average rate of change (m) of a function on an interval is the difference between the function values at the ends of the interval, divided by the interval width:
[tex]m_{ab}=\dfrac{f(b)-f(a)}{b-a}\qquad\text{average rate of change on interval $[a,b]$}[/tex]
__
simplificationHere, the interval of concern is the same for all of the functions. It is [a, b] = [0, 2] so the denominator of this fraction is 2-0 = 2 for all of the functions. That means we can determine the greatest average rate of change by simply looking at the differences f(2) -f(0) for each of the functions.
amount of changeA. j(2) -j(0) = 3(1.6²) -3 = 4.68
B. g(2) -g(0) = 25/2 -8 = 9/2 = 4.5
C. k(2) -k(0) = 9 -4 = 5 . . . . . . . . . . greatest amount of change
D. f(2) -f(0) = 1.5(2²) -1.5 = 4.5
solutionThe function k(x) has the greatest average rate of change over the interval [0, 2].
