PLEASE I NEED THESE TODAY!!!!
what's the question? we solving or simplify?
Answer and Step-by-step explanation:
When multiplying exponents:
- Product of Powers: When the base of the exponents are the same, and the bases are being multiplied to each other, the exponents are added together.
- Different bases Same Exponents: When the bases of the exponents are different, but the exponents are the same, the bases multiply together (within a parenthesis) with the exponent on the parenthesis.
- Quotient of Powers: When the base of the exponents are the same, and they are being divided by each other, the exponents will subtract from each other.
- Power of a Power: When a base has an exponent, and that entire term has and exponent, the exponents multiply together.
- Power of a Product: The opposite of Different bases Same Exponents. Distribute the exponent onto the different bases.
- Power of a Quotient: The opposite of Quotient of Powers. Distribute the exponent to the dividing bases.
- Zero Power: Any number raised to the 0 power equals 1.
- Negative Exponent: Any number raised by a negative number goes to the denominator of a fraction (if not already in the denominator), and vise versa (goes to the numerator if not already in the numerator).
- Power of One: Any number raised to the power of 1 is the same number.

Part A: If (2^6)^x = 1, what is the value of x? Explain your answer.
Part B: If (5^0)^x = 1, what are the possible values of x? Explain your answer.
2 points for each answer; 2 points for each explanation.
Answer:
Step-by-step explanation:
2^6 = 64 and the only power of 64 that gives us 1 is 64^0 = 1. S0 x = 1.
Now 5^0 is already 1. Then (5^0)^x =1^x is equal to 1 for any value of x.

6. Write an equation for the line that passes through (-4,4) and (8,8) in point-slope
form, slope-intercept form and standard form.
Point-Slope Form:
Slope-Intercept Form:
Standard Form:
Help!!
Answer:
Point-slope form:
[tex]y-4=\displaystyle\frac{1}{3}(x+4)[/tex]
[tex]y-8=m(x-8)[/tex]
Slope-intercept form:
[tex]y=\displaystyle\frac{1}{3}x+\displaystyle\frac{16}{3}[/tex]
Standard form:
[tex]-x+3y=16[/tex]
Step-by-step explanation:
Hi there!
1) Point-slope form
Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where [tex](x_1,y_1)[/tex] is a point on the line and m is the slope
First, determine the slope:
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-4,4) and (8,8):
[tex]m=\displaystyle\frac{8-4}{8-(-4)}\\\\m=\displaystyle\frac{8-4}{8+4}\\\\m=\displaystyle\frac{4}{12}\\\\m=\displaystyle\frac{1}{3}[/tex]
Therefore, the slope of the line is [tex]\displaystyle\frac{1}{3}[/tex]. Plug this into [tex]y-y_1=m(x-x_1)[/tex]:
[tex]y-y_1=\displaystyle\frac{1}{3}(x-x_1)[/tex]
Now, for [tex](x_1,y_1)[/tex], we can either plug in (-4,4) or (8,8):
[tex]y-4=\displaystyle\frac{1}{3}(x-(-4))\\\\y-4=\displaystyle\frac{1}{3}(x+4)[/tex]
or
[tex]y-8=m(x-8)[/tex]
2) Slope-intercept form
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
[tex]y=mx+b[/tex]
Plug in the slope
[tex]y=\displaystyle\frac{1}{3}x+b[/tex]
Now, to determine the y-intercept, plug in one of the points (-4,4) or (8,8) and solve for b:
[tex]8=\displaystyle\frac{1}{3}(8)+b\\\\8=\displaystyle\frac{8}{3}+b\\\\8-\displaystyle\frac{8}{3}=b\\\\b=\frac{16}{3}[/tex]
Therefore, the y-intercept is [tex]\displaystyle\frac{16}{3}[/tex]. Plug this back into [tex]y=\displaystyle\frac{1}{3}x+b[/tex]:
[tex]y=\displaystyle\frac{1}{3}x+\displaystyle\frac{16}{3}[/tex]
3) Standard form
Standard form:
[tex]Ax+By=C[/tex] where A, B, and C are numbers which are typically integers
[tex]y=\displaystyle\frac{1}{3}x+\displaystyle\frac{16}{3}[/tex]
Organize this into standard form:
[tex]-\displaystyle\frac{1}{3}x+y=\displaystyle\frac{16}{3}[/tex]
Multiply both sides by 3 so A, B, and C are integers:
[tex]-x+3y=16[/tex]
I hope this helps!

What is 15 percent of 1135? Explain how you came up with your solution and the actions you took.
Answer:
170.25
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 15 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 15, so we can write it down as 100%=15.
4. We know, that x% equals 1135 of the output value, so we can write it down as x%=1135.
5. Now we have two simple equations:
1) 100%=15
2) x%=1135
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=15/1135
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 1135 is what percent of 15
100%/x%=15/1135
(100/x)*x=(15/1135)*x - we multiply both sides of the equation by x
100=0.013215859030837*x - we divide both sides of the equation by (0.013215859030837) to get x
100/0.013215859030837=x
7566.6666666667=x
x=7566.6666666667
now we have: 170.25
We have to find,
→ 15% of 1135
The value of the percentage is,
→ 15 ÷ 100
→ 0.15
Let's find the solution,
→ 1135 × 0.15
→ 170.25
Hence, the answer is 170.25.
Which fraction is greater,2/3 or 25/15?
Answer:
[tex]\frac{25}{15}[/tex] is greater.
Step-by-step explanation:
25÷15=1.67
2÷3=0.67
1.67 is greater than 0.67, so [tex]\frac{25}{15}[/tex] is greater.
Also, [tex]\frac{25}{15}[/tex] is an improper fraction, and [tex]\frac{2}{3}[/tex] is a proper fraction. Improper fraction mast be greater than a proper fraction.

WILL MARK BRAINLEST HELP HELP HELP.
Answer:
the point is (1.73, 3)
Step-by-step explanation:
Given a vector on an xy plot, the magnitude is the hypotinuse of the triangle formed, and the direction is the angle with x axis. So we have a right angle triangle that must be a 30-60-90 (sum = 180).
Then from the lower angle
sin(60) = opposite/hypotinuse = y/(2*3**(1/2))
0.866 = y/(2*1.732)
0.866 = y/3.464
0.866 * 3.464 = y
3 = y
Then from the top angle
sin(30) = opposite/hypotinuse = x/(2*3**(1/2))
sin(30) = x/(2*3**(1/2))
0.5 = x/(2*3**(1/2))
0.5 = x/3.464
0.5 * 3.464 = x
1.73 = x

suppose a 13 foot ladder is leaning against a building. Reaching to the bottom of a second floor window 12 ft above the ground. How far is the base of the ladder from the building? Round your answer to the nearest 10th
5 ft
4ft
3ft
6ft
Answer: First Choice. 5ft
Step-by-step explanation:
Here we need to know the idea of the Pythagorean theorem.
Since a building is straight, the base angle is a right angle, thus it would be a right triangle.
Pythagorean Theorem: a² + b² = c²
**NOTE** Please refer to the attachment below for the figure. (I drew it, so if it was not clear and understandable for you, please tell me.)
Solve:
Given information
a = 12 ft
c = 13 ft
b = unknow base length
Given formula for Pythagorean Theorem
a² + b² = c²
Substitute values into the formula
12² + b² = 13²
Simplify exponents
144 + b² = 169
Subtract 144 on both sides
144 + b² - 144= 169 - 144
b² = 25
Square root both sides
√b² = √25
