PLEEASSEEEE Answer ASAP. Due in 5 Minutes. 25 points!!!!!!!!!
Answer:
Here we will use the relationships:
[tex]a^n*a^m = a^{n + m}[/tex]
[tex](a^n)^m = a^{n*m}[/tex]
[tex]\frac{a^n}{a^m} = a^{n - m}[/tex]
And a number:
[tex]a^n[/tex]
is between 0 and 1 if a is positive and larger than 1, and n is negative.
if a is positive and 0 < a < 1, then we need to have n positive such that:
0 < a^n < 1
A) [tex]5^3*5^{-4} = 5^{3 + (-4)} = 5^{-1}[/tex]
This is between zero and 1,
B) [tex]\frac{3^5}{3^{-6}} = 3^{5 - (-6)} = 3^{11}[/tex]
This is greater than 1, because the exponent is positive.
C) [tex](\frac{1}{4})^3*( \frac{1}{4})^2 = (\frac{1}{4})^{2 + 3} = (\frac{1}{4})^5[/tex]
Because a is smaller than 1, and the exponent is positive, then the expression is between 0 and 1.
D) [tex]\frac{(-7)^5}{(-7)^7} = (-7)^{5 - 7} = -7^{-2}[/tex]
The exponent is negative (and pair) then the expression is between 0 and 1.
Remember that when the exponent is pair, we always have that:
(-N)^m = (N)^m
So (-7)^-2 = 7^-2
Last week Jack ran 18 miles more than Pranav. Jack ran 34 miles. How many miles did Pranav run?
Hello there!
Step-by-step explanation:
If Jack runs 34 miles, and Pranav runs 18 less, this signifies that we need to subtract 18 from Jack's total miles to get his miles ran.
34 - 18 = 16
Pranav ran 16 miles.

What is the value of f(-2) when f(x) = 2x2−3x+28
Answer:
f(2) = 30
Step-by-step explanation:
f(x) = 2x² − 3x + 28
f(2) = 2(2)² - 3(2) + 28
f(2) = 2(4) - 6 + 28
f(2) = 8 - 6 + 28
f(2) = 30
Use the quadratic formula to solve for x.
8x²-7x+1=0
(there may be more than one solution, if so, separate them with commas.)
x = _

A mine worker is in a tunnel 25 feet below the ground. He descends another 13 feet. What is his final position? i already know that part of the answer is -25 -
but is it -25 - 13 or -25 - -13
Answer: -25 - 13
This simplifies to -38
So the worker's final position is 38 feet below the ground.
A diagram is shown below.
==========================================================
Explanation:
Draw a vertical number line. Plot 0 on it to indicate the ground level, or surface level. Then plot -25 on it, which is below 0. This is 25 feet below the ground.
To move 13 further feet downward, we will subtract 13 from -25. Subtracting a positive means we move downward.
For example, start at the 30th of a building. This is marked as +30 or just 30 on the vertical number line. Subtract off 13 to go down 13 floors and we have 30-13 = 17. So after going down 13 floors, we're at the 17th floor now.
Going back to the problem at hand, we start at -25 and subtract off 13 to get the final answer -25 - 13
The answer is not -25 - -13 and it is not -25 - (-13). This is because the two negatives cancel to be a positive. So -25 - (-13) becomes -25+13. Here we're starting at -25 but then going up 13 feet. Instead we want to go down 13 feet.
------------------------------------
After we determine the expression is -25 - 13 we will effectively add the positive versions of those numbers like so
25+13 = 38
But the final answer is negative because we're starting underground and moving further underground.
We can write it like this
-25 - 13 = -(25+13) = -(38) = -38
Therefore, if the worker starts off 25 feet underground, and moves 13 feet downward, then the worker ends up 38 feet underground. Again, use the vertical number line to help see this.
Check out the diagram below.

Step-by-step explanation:
[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ a1 = 20 \\ a2 = 16 \\ d = - 4 \\ an = 20 + (n - 1) \times - 4 \\ an = 20 - 4n + 4 \\ an = 24 - 4n \\ a23 = 24 - 4 \times 23 \\ a23 = - 68[/tex]
A triangle has one angle that measures 70 degrees, one angle that measures 42 degrees, and one angle that measures 68 degrees. What kind of triangle is it?
Answer:
Scalene Acute Triangle
Step-by-step explanation:
The triangle above is an "acute triangle" because the measurement of each angle is less than 90°. However, there are three types of acute triangle and these are: Equilateral Acute Triangle, Isosceles Acute Triangle and Scalene Acute Triangle.
When all the angles have the same measurement of less than 90°, then it is an Equilateral Acute Triangle. If only two angles have the same measurement, it is an Isosceles Acute Triangle. If none of the angles are the same but all are less than 90°, which also means that the sides are also unequal, then it is an Scalene Acute Triangle.
The triangle above has different angle measurements of less than 90°. Therefore, it is an Scalene Acute Triangle.
The algebraic rule for a reflection over the x-axis is one for the following:
A. (x,y), -axis → (-x,y)
B. (x,y), -axis → 0,x)
C. (x,y), -axis → (x,- y)
D. (x,y)x-axis →(-x-y)
Answer:
C
Step-by-step explanation:
When reflecting around the x axis, the x value stays the same and the y- will change.

Step-by-step explanation:
Is x = 6 a solution to the equation 5(x – 3) = x + 13?
Follow the steps to find out.
1. Rewrite the equation 5(x – 3) = x + 13 with 6 substituted for x. Write a question mark over the equal sign to show that you're testing to see if the equation is true.
ill give brainliest
Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:
x-4y=6
x+4y=12
we see here that elimination would best fit:
x+x+4y-4y=6+12
or:
x=2y-3
7x+3y-81=23
substitute (2y-3) for x.

Find the circumference of the circle.
A: 47,1 in
B: 22 in
C: 10.5 in
D: 35 in
Answer:
C≈47.12, or 47.1
Step-by-step explanation:
To find the circumference you just use the formula C=2[tex]\pi[/tex]r.
The radius of your circle is 7.5 which is half of 15, now multiply 2[tex]\pi[/tex](7.5) which gives you your answer!
An even easier way to do this is to use the other formula C=d[tex]\pi[/tex],
Just multiply your diameter (which is what was given to you) by pi and you also get your answer!
Hope this helps! :)
