The difference of 7 and the square of a number.
Answer:
Step-by-step explanation:
I can only show you what the answer is.
7 - x^2.
Be careful which one you put first. Unless told otherwise, the first number mentioned goes before the minus sign.
why do you multply by a power of 10 when writing a repeating decimal as a fraction
The goal is to multiply by a certain number (10, 100, 1000, etc.) so that when the original number is subtracted from the multiple, the repeating element cancels out. 10x = 2 is the result of multiplying by ten.

Answer:
Step-by-step explanation:
He has done one half = ½
Finding ½ of 14
½ × 14
7
Hence, Hong has memorized 7 words

The function f(x) is shown on the graph. If f(x) = 0, what is x?
A: 0 only
B: -6 only
C: -2, 1, or 3 only
D: -6, -2, 1, or 3 only
Answer:
C
Step-by-step explanation:
note y = f(x) = 0
y = 0 is the x- axis
We are looking for values of x on the x- axis where the graph crosses/touches
This occurs at
x = - 2, x = 1, x = 3 → C
Look at this table:
Is this relation a function?
Answer:
Yes, because each x-value has a different y-value.
PLS HELP NEED ASAP in 10 mins
Answer:
A
Step-by-step explanation:
All you have to do is replace the x value in the equation g(x) with whatever value x is in the tables given. An example would be as follows:
x = -2 replace x with -2
-1/2( 4(-2) + 6 )
now use pemdas to finish the equation.
you will get g(x) = 1.
Therefore, your answer is the first table, (aka A)

PLS ANS CLEARLY
The rule is
[tex]\frac{d}{dx}x^n = nx^{n-1}[/tex]
which is the power rule. You pull down the exponent to place it as the coefficient. So that explains the 1/2 pull out front. Then we subtract 1 from the exponent.
The expression you wrote can be simplified or rewritten like this
[tex]\frac{d}{dx}x^n = nx^{n-1}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}x^{\frac{1}{2}-1}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}x^{-\frac{1}{2}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}\frac{1}{x^{\frac{1}{2}}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2x^{\frac{1}{2}}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2\sqrt{x}}}\\\\[/tex]
Optionally, we can multiply top and bottom by [tex]\sqrt{x}[/tex] to rationalize the denominator.
3/10 of the members of a tennis club are men. 5/6 of these men are right handed. work out the fraction of members of the tennis club who are right handed
Answer:
1/4 of the men are right handed.
Step-by-step explanation:
You know nothing about the women. You know only about the men, so the answer has to be expressed in terms of men.
3/10 * 5/6 = 15 / 60 = 1/4

Hope This Helps Youa ballroom had a square dance floor. The area of the floor is 400 square feet. If the length of each side of the square increased by one foot, would its area be a rational number?
Answer:
Yes
Step-by-step explanation:
The area of a square is equal to the length squared.
So, the length of one side of the original floor is √400 which equals 20.
If you increase the length by 1, the area of the dance floor is 21 squared.
21 * 21 is certainly a rational number.
Answer:
Step-by-step explanation:
I think so, yes.
The area of a square is A = s*s where s is the length of the side
s^2 = 400
sqrt(s^2) = sqrt(400)
s = 20
If you increase each dimension by one foot you get 21 * 21 for the area of the new ballroom.
The result is rational. That's because the square root was rational when you found 20.
Area = 21 * 21 = 441 which is rational.

Answer:
a. dbc = 66, ABC = 132
b. abd = 52, dbc= 52
Step-by-step explanation:
just remember that bisects means that the angles on either side of the middle line are equal. so for a, dbc = abd and ABC = 2x 66
for b, abd and dbc are equal, so both of them are just 104 divide by two
