Jeremy is trying to explain why a triangle with side lengths 35, 30, 60 is not a right triangle. His explanation is shown below.
Step 1: 35 squared + 30 squared question mark equals 60 squared
Step 2: (35 + 30) squared question mark equals 60 squared
Step 3: 65 squared question mark equals 60 squared
Step 4: 4,225 not-equals 3,600
Which best describes Jeremy’s explanation?
Jeremy’s explanation is accurate.
Jeremy’s explanation is inaccurate. He wrote the leg lengths in the incorrect order in step 1.
Jeremy’s explanation is inaccurate. He incorrectly combined terms in step 2.
Jeremy’s explanation is inaccurate. He multiplied incorrectly in step 4.
Answer:
i would say a is the correct answer
Answer:
He incorrectly combined terms in step 2
Step-by-step explanation:
In Step 2, you can't combine 30² + 35² into (30 + 35)² so the answer is "He incorrectly combined terms in step 2".

Which rule describes the composition of transformations that maps ΔABC to ΔA"B'C"?
Answer:
The Answer is A or the first one, NOT C. C is wrong.
Step-by-step explanation:
The transformations that map ΔABC to ΔA"B"C" will be reflection cross x-axis and translation of (x - 6, y - 2). Then the correct option is B.
What is a transformation of a shape?A point, line, or numerical figure can be changed over in one of four ways, and each affects the item's design as well as position. Picture, after interpretation, alludes to the article's definitive association and situation. Not long before the alludes to the material's underlying condition.
The interpretation doesn't change the shape and size of the calculation. However, changes the area.
The reflection doesn't change the shape and size of the math. However, flipped the picture.
The changes that map ΔABC to ΔA"B"C" will be reflection cross x-pivot and interpretation of (x - 6, y - 2). Then, at that point, the right choice is B.

An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorption into the skin. Eight locations on the forearm were designated for ointment application. The new ointment was applied to five locations, and a control was applied to the other 3. How many different choices were there for the five locations to apply the new ointment
Answer:
There were 56 different choices for the five locations to apply the new ointment.
Step-by-step explanation:
The order of the locations in which the new ointment was applied is not important. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
How many different choices were there for the five locations to apply the new ointment
Five locations from a set of 8. So
[tex]C_{8,5} = \frac{8!}{5!(8-5)!} = 56[/tex]
There were 56 different choices for the five locations to apply the new ointment.

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 80 degrees at midnight and the high and low temperature during the day are 89 and 71 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
Answer:
The equation is given by:
[tex]D(t) = 80 + 9\sin{0.2618t}[/tex]
Step-by-step explanation:
Sine function:
Has the following format:
[tex]y = A\sin{bx}[/tex]
In which A is the amplitude and [tex]\frac{2\pi}{b}[/tex] is the period.
Suppose you know the temperature is 80 degrees at midnight and the high and low temperature during the day are 89 and 71 degrees
This means that the amplitude of the sinusoidal variation function is 89 - 80 = 80 - 71 = 9. This means that [tex]A = 9[/tex]
During a 24-hour day, which means that the period is 24. So
[tex]\frac{2\pi}{b} = 24[/tex]
[tex]24b = 2\pi[/tex]
[tex]b = \frac{2\pi}{24}[/tex]
[tex]b = 0.2618[/tex]
So the variation is:
[tex]V(t) = 9\sin{0.2618t}[/tex]
Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
Initial temperature of 80, so:
[tex]D(t) = 80 + V(t) = 80 + 9\sin{0.2618t}[/tex]
at what points is the function y= cosx/4x continuous

Answer:
5 miles
Step-by-step explanation:
Time/speed/distance problems can be worked a number of ways. Here, we want to know the distance walked. We know the total time and the total distance and the two different speeds. So, we can use a variable to represent the value we want to know: w = distance walked (in miles).
The total time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours.
The total time is the sum of times for the two parts of the trip: walking and riding.
walking time = walking distance/walking speed
= w/3
riding time = riding distance/riding speed
= (20-w)/30
The total time is that given above:
w/3 +(20-w)/30 = 13/6
10w +(20 -w) = 65 . . . . . . . . multiply by 30
9w = 45 . . . . . . . . . . . . subtract 20, collect terms
w = 5 . . . . . . . . . . . divide by 9
The girl walked 5 miles.

y = n^2 +nupper left corresponds to n^2; lower right corresponds to nStep-by-step explanation:
The number of squares in the upper left portion of the figure is the number in a square n on a side, so is n^2. The number of squares in the lower right portion of the figure is equal to the step number, n. A suitable equation adds these numbers together.
y = n^2 +n . . . . where y is the number of squares in the pattern of Step n.
