Explain the algebraic error in the student's work.
Then, state how the equation r = (A- P)/t can be
modified to produce the correct result.

Answers

The student forgot to distribute the P into rt as well in the second line.

So, to solve for r correctly:

C. a sinus infection
D. caffeinated soda

Answers

Answer:

Step-by-step explanation:

For example, a tumor would be found in MRIs and will have a significant impact on the results and interpretation of a functional MRI. A tumor that is cancerously growing is very crucial to the function of an MRI

The functional MRI also known as fMRI monitors brain anatomy activity

The factor that is least likely to affect the results and interpretation of a

functional MRI is; C. A sinus infection.

Reasons:

MRI stands for magnetic resonance imaging, and it is used to generate

images of the interior of items, such as the human body, without opening

the body, by producing strong magnetic fields, from the built in powerful

magnets.

The parts of the body that are examined by an MRI scan includes, the

internal organs, blood vessels, brain, and spinal cord.

The MRI scan works by tracking radio signals sent by protons in the body

which vary based on the type of tissue.

Due to the requirement for the patient to remain stationary during the

scan, medication may be given. It is also important to not take caffeinated

drinks prior to the examination.

A functional MRI is used to monitor the functioning of the brain's anatomy,

by blood flow change detection.

Therefore, the factor that is least likely to affect the result and

interpretation of a functional MRI is a sinus infection which is the

inflammation of the sinus lining and mucus presence, that rarely cause

neurologic complications.

How far above ground is the flag pole in inches? Round to nearest inch if needed

Answers

Answer:

Step-by-step explanation:

You'll use similar triangles to solve this. Set up 2 ratios as a proportion. First, however, you have to convert the 15 inches to feet. If everything else is in feet, then EVERYTHING has to be in feet. 15 inches is equal to 1.25 feet. Now for the equation:

[tex]\frac{3}{x} =\frac{1.25}{6}[/tex]

The first fraction is made up of the heights, 3 being the height of the plumb bob and x being our unknown height of the flagpole; the second fraction is made up of the distances on the ground. Cross multiply to solve:

1.25x = 18 so

x = 14.4 feet, or 14 feet, 4.8 inches

Jay is saving two-thirds of his savings account for his college education. If he has set aside $2500 from his savings for his college education, how much money, in total, is in his savings account? Write an equation to model and solve the problem. Explain the answer in terms of the problem

Answers

Answer:

[tex]\dfrac{2}{3}x = \$ 2500[/tex]

$3750

Step-by-step explanation:

Given that:

Jay saves [tex]\frac{2}{3}^{rd}[/tex] of the savings account for his college education.

Money set aside for the college education = $2500

To find:

Total money present in the savings account of Jay = ?

Solution:

Let the total money in the savings account be $[tex]x[/tex].

As per question statement:

[tex]\dfrac{2}{3}x = \$ 2500[/tex]

The equation to model the problem is:

[tex]\dfrac{2}{3}x = \$ 2500[/tex]

Now, let us solve the above equation:

[tex]\Rightarrow 2x =3\times 2500\\\Rightarrow x = \dfrac{7500}{2}\\\Rightarrow x = \bold{\$ 3750}[/tex]

Total money saved in the savings account is $3750.

Out of the total money $2500 is saved for college education.

Write an equation for the parabola that passes through (1,12) and has vertex (10,-4)

Answers

Answer:

y + 4 = (16/81)(x - 10)

Step-by-step explanation:

The general formula for a parabola passing through (x, y) and with vertex (h, k) is                  y - k = a(x - h)^2.

Here we are told that x = 1, y = 12, h = 10 and k = -4, which gives us:

                         12 + 4 = a(1 - 10)^2, or

                              16  =  81a

Then a = 16/81, and the desired parabola is

                                  y + 4 = (16/81)(x - 10)

The solution is p + 12.

Answer:

p+12

Step-by-step explanation:

I'm assuming you want me to simplify this equation. Okay, first, we eliminate the redundant parenthesis. Now, we have 6p+4+-5p+8, we can simplify this to 6p+4-5p+8 because adding a negative has the same effect as subtraction. Now, we combine like terms (6p and -5p, and 4 and 8). From this, we have 1p+12 (4+8=12, and 6p-5p=1p, or just p). We can simplify this even more to get p+12. I hope this helps!
