Raymond was asked to solve for the length of the hypotenuse in a right triangle with legs that have side lengths of 4 and 5. His work is shown below. He made a mistake when solving. Explain the mistake and then solve the problem correctly.
Raphael's Solution:
a ^ 2 + b ^ 2= c^2 (to the power of 2)
4^2 + 5^2=c^2
16 + 25= c^2
41= c
Answers
Answer:
Raymond's mistake was on the last step, since he didn't square root both sides
The correct answer should be
[tex]c = \sqrt{41}[/tex]
Step-by-step explanation:
[tex]a^2 + b^2 = c^2\\4^2 + 5^2 = c^2\\16 + 25 = c^2\\c^2 = 41\\c = \sqrt{41}[/tex]
Good luck!

Find the equation of the exponential function represented by the table below:
х
Y
0
3
1
1.5
2
0.75
3
0.375
Answers
Given:
The table of values.
To find:
The equation of the exponential function represented by the table.
Solution:
The general form of an exponential function is
[tex]y=ab^x[/tex] ...(i)
where, a is initial value and b is growth factor.
From the given table it is clear that the function passes through (0,3) and (1,1.5). So, the must be satisfy by these points.
Putting x=0 and y=3 in (i), we get
[tex]3=ab^0[/tex]
[tex]3=a(1)[/tex]
[tex]3=a[/tex]
Putting a=3, x=1 and y=1.5 in (i), we get
[tex]1.5=3b^1[/tex]
[tex]\dfrac{1.5}{3}=b[/tex]
[tex]\dfrac{1}{2}=b[/tex]
Putting [tex]a=3[/tex] and [tex]b=\dfrac{1}{2}[/tex] in (i), we get
[tex]y=3\left(\dfrac{1}{2}\right)^x[/tex]
Therefore, the required equation for exponential function is [tex]y=3\left(\dfrac{1}{2}\right)^x[/tex].

Which of the following best describes the slope of the line below?
O A. Undefined
B. Zero
C. Positive
D. Negative
Answers
Answer:
I believe it would be A: Undefined
The answer is A. Undefined.
When the value of slope is a lot. The graph will head toward the y-axis. More values, more to y-axis. So we don't know what is the slope when the graph is like this but classified as undefined

2. A recipe calls for 3 and 1/2 cups of flour and 3/4 cups of sugar, If you want
to make the recipe with 6 cups of flour, how much sugar will you need? *
Answers
Answer:
1 and 2/7 cups of sugar.
Step-by-step explanation:
The ratio of the amount of flour in the original recipe to the amount in your recipe is 1:12/7. (6 / 7/2 = 6 * 2/7 = 12/7)
Therefore, the amount of sugar you need can be found by 3/4 * 12/7 = 36/28 = 9/7 cups of sugar, which equates to 1 and 2/7 cups.

If there are 90 calories in Three-fourths cup of yogurt, how many calories are in 3 cups of yogurt?
A= 30 calories
B= 202 calories
C= 270 calories
D= 360 calories
Answers
Answer:
360
Step-by-step explanation:
360 calories:
90/(3/4)=120 (calories in one cup)...
120*3=360
Answer: D = 360 calories
Step-by-step explanation:
90 divided by 3/4 = 120
so you would multiply 120 by 3 to get your answer
120 * 3 = 360

Scott likes to run long distances. He can run 20 km in 85 minutes. He wants to know how many minutes (m) it will take him to run 52 km, at the same pace.
How long will it take Scott to run 52km?
Answers
Answer:
221 minutes
Step-by-step explanation:
52 divided by 20 would be 2.6 then you take the 85 and mulitpy it by 2.6 because 52 is 2.6 times more than 20. so 85 times 2.6 would be 221 minutes.

Answers
Explanation:
An altitude goes from a vertex point to the opposite side, such that it is perpendicular to the opposite side. The square angle marker indicates we have a 90 degree angle, so DB is perpendicular to AC. The altitude of a triangle, DB, is the height of the triangle with base AC. The base and height are always perpendicular to one another.
