D, [tex]\frac{1}{2}x-3[/tex]
Step-by-step explanation:
Remember order of operations: parentheses first, then exponents, then multiplication/division, and finally addition/subtraction.
In this case, since there is no way to further simplify the parentheses, we can leave them be. But the negative sign in front of the parentheses is like multiplying it by -1. It needs to be distributed into the parentheses like so:
[tex]-(\frac{1}{4}x+5)=-\frac{1}{4}x-5[/tex]
We can now substitute that into the expression:
[tex]\frac{3}{4}x+2-\frac{1}{4}x-5[/tex]
From here, we can combine like terms:
[tex]\frac{2}{4}x-3[/tex]
And finally, we can simplify 2/4 to get:
[tex]\frac{1}{2}x-3[/tex]
show that
[tex]3 \frac{3}{4} \div 1 \frac{1}{3 } = 5 \frac{1}{12} [/tex]

To avoid a service fee, your checking account balance must be at least $500 at the end of each month. Your current balance is $525.17. You use your debit card to spend $117.08. What possible amounts can you deposit into your account by the end of the month to avoid paying the service fee?
Answer: At least $91.91
Step-by-step explanation:
From the question, we are informed that to avoid a service fee, the checking account balance must be at least $500 at the end of each month.
Since the current balance is $525.17 and $117.08 has been spent, the balance will now be:
= $525.17 - $117.08
= $408.09
Since the checking account balance must be at least $500 at the end of each month and we currently have $408.09, this means that there will still be a need to add $91.91.
= $500 - $408.09
= $91.91
At least $91.91 must be added to avoid the fee.

Changing the subject of an equation involves solving for another variable in the equation
The equation of t is [tex]t=\frac{\sqrt{y_i-y_o}}{N}[/tex]
How to change the subject of the equationThe equation is given as:
[tex]N=\sqrt[2]{\frac{y_i-y_o}{t^2}}[/tex]
Rewrite the equation as:
[tex]N=\sqrt{\frac{y_i-y_o}{t^2}}[/tex]
Evaluate the square root of t^2
[tex]N=\frac{\sqrt{y_i-y_o}}{t}[/tex]
Multiply both sides by t
[tex]Nt=\sqrt{y_i-y_o}[/tex]
Make t the subject, in the above equation

Asia contains both the highest and lowest known points on earth. Mt. Everest is a little over 29,000 feet above sea level, and the shore of the Dead Sea is about 1,370 feet below sea level. What is the approximate difference in elevation between the two points?
Answer:
30,370 feet
Step-by-step explanation:
Given that,
Mt. Everest is a little over 29,000 feet above sea level, and the shore of the Dead Sea is about 1,370 feet below sea level.
We need to find the approximate difference in elevation between the two points.
29,000 feet is above sea level and 1,370 feet is below sea level i.e. both elevations are in opposite direction.
Difference = 29,000 - (-1,370 )
= 30,370 feet
Hence, the difference in elevation between the two points is 30,370 feet.
Answer:30,370 feet

What is the value of the discrimination for the quadratic equation 0= x+2+x2?
Discriminant =b2 - 4ac
Answer:
The value of discriminant is -7.
Explanation:
The given equation is,

Find the Derivative y’ implicitly.
[tex]e^{x^2y} - e^y = e^y(e^{x^2} - 1) = x[/tex]
We should ISOLATE x
[tex]e^y= \frac{x}{e^{x^2} - 1}[/tex]

[tex]y = ln(\frac{x}{e^{x^2}-1})[/tex]

[tex]y' = \frac{1}{\frac{x}{e^{x^2}-1}} * \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)^2}= {\frac{e^{x^2}-1}{x}}* \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)^2} = {\frac{1}{x}}* \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)} = {\frac{1}{x}}* \frac{(e^{x^2}-1 - 2x^2e^{x^2})}{(e^{x^2}-1)}[/tex]
Enter the first 4 terms of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.
f(1) = 390,625, f (n) = f (n − 1)
The first 4 terms of the sequence are ____, ____, ____, and ____.
Answer:
The first four terms is: 390625, 625, 25, 5
Step-by-step explanation:
Given
[tex]f(n) = \sqrt{f(n-1)}[/tex]
To determine the first 4 terms.
We have
[tex]f(1) = 390625[/tex]
[tex]f(2) = \sqrt{f(2 - 1)}[/tex]
[tex]f(2) = \sqrt{f(1)}[/tex]
Substitute 390625 for f(1)
[tex]f(2) = \sqrt{390625}[/tex]
[tex]f(2) = 625[/tex]
For f(3), we have
[tex]f(3) = \sqrt{f(3-1)}[/tex]
[tex]f(3) = \sqrt{f(2)[/tex]
[tex]f(3) = \sqrt{625[/tex]
[tex]f(3) = 25[/tex]
For f(4), we have
[tex]f(4) = \sqrt{f(4-1)[/tex]
[tex]f(4) = \sqrt{f(3)[/tex]
[tex]f(4) = \sqrt{25[/tex]
[tex]f(4) = 5[/tex]
Hence, the first four terms is:
390625, 625, 25, 5

0.5 1.1252 3.125 4.5What is a speed?Speed is known to be the distance that is said to be traveled and it is per unit of time. It is seen as the rate of which an object is said to be moving.
Note that Speed is calculated in this case as 1/2mv².
Therefore, to calculate the variables are:
If the speed of the bottle is 2 m/s, then
= ½ (0.250) (2) ^2
= 0.5
If the speed of the bottle is 3 m/s, then
= ½ (0.250) (3) ^2

If the speed of the bottle is 4 m/s, then
= ½ (0.250) (4) ^2.
= 2
If the the speed of the bottle is 5 m/s, then
= ½ (0.250) (5) ^2
