The number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
It is given that:
The number expression is:
= 5⁻¹⁵
By the property of the integer exponent we can write the above number exponent as follows:
= (5¹⁵)(-1)¹⁵
(-1)¹⁵ = -1 (because 15 is the odd number)
= -5¹⁵
Thus, the number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.

Point M is the midpoint of AB. The coordinates of point A are (−7, 1) and the coordinates of M are (−2, 2). What are the coordinates of point B?
Answer:
[tex]\huge{\boxed{\sf{ ( 3 , 3 ) }}}[/tex]
Step-by-step explanation:
Co-ordinates of point A = ( -7 , 1 )
Co-ordinates of point M = ( -2 , 2 )
Let the co-ordinates of point B be ( x , y )
A ( -7 , 1 ) [tex]\longrightarrow[/tex] ( x1 , y1 )
B ( x , y ) [tex]\longrightarrow[/tex] ( x2 , y2 )
Now,
Midpoint = [tex](\frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
⇒[tex]( -2 , 2 ) = ( \frac{-7 + x}{2} , \frac{1 + y}{2} )[/tex]
Finding the value of x :
⇒[tex]-2 = \frac{-7 + x}{2}[/tex]
Do cross multiplication
⇒[tex]-4 = -7 + x[/tex]
⇒[tex]-7 + x = -4[/tex]
⇒[tex]x = -4 + 7[/tex]
⇒[tex]x = 3[/tex]
Now, finding the value of y
⇒[tex]2 = \frac{1+y}{2}[/tex]
Do cross multiplication
⇒[tex]4 = 1+y[/tex]
⇒[tex]1+y = 4[/tex]
⇒[tex]y = 4 - 1[/tex]
⇒[tex]y = 3[/tex]
Hence, The co-ordinates of point B = ( 3 , 3 )

What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the coordinate (3,-2) transformed in coordinate (1,0)
Now,
3 + x = 1
x = -2
It means graph shift 2 units left.
Now,
-2 + y = 0
y = 2
It means the graph shifts 2 units up.
Hence "The translation of points (3,-2) → (1,0) is 2 units up and 2 units left".

Let f be a differentiable function with selected values given in the table above. What is the average rate of change of f over the closed intervals 0<_ x <_10?
Answer:
B
Step-by-step explanation:
The average rate of change is synonymous with the slope.
So, essentially, we want to find the average slope of our function f(x) from x=0 to x=10.
So, we will use the two following points: (0,5) and (10, -20).
Recall the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, 5) be (x₁, y₁) and (10, -20) be (x₂, y₂). Substitute. This yields:
[tex]m=\frac{-20-5}{10-0}[/tex]
Subtract and reduce:
[tex]m=-25/10=-5/2[/tex]
So, the average slope of f(x) between x=0 and x=10 is -5/2.
Our answer is B.
And we're done!

Tonya’s dog-walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. Beth does not charge a monthly fee for her dog-walking service, but she charges $5 per mile that each dog is walked.
Part A
Choose the equation that can be used to find the number of miles m for which Tonya and Beth would charge the same amount.
A. 20 + 3m = 5m
B. 20 = 3m + 5m
C. 20 + 5m = 3m
D. 20 + m = 8m
Part B
m = _____ miles
Answer:
A 10 miles
Step-by-step explanation:
If I'm not mistaking I'm pretty sure we can write the two problems with an equal sign between as we're trying to find the same amount.
Using this information, we know that we Automatically have a +20 charge with a 3 dollar charge for every mile walked. Now we have 20+3x=
Now we plug in the 5x to get 20+3x=5x
From here you subtract 3x and you get 20=2x. Now divide!
10=x

The radius of Earth is about 6.38 x 10³ kilometers. Write this distance in standard notation
6.38 * 10^3 = 6380 kilometers.
Hope this helped!
Answer:
6380km
Step-by-step explanation:
10³ is just 1000 if you think about it.
6.38 multiplied by 1000 would just mean you need to move the decimal to the right 3 times.
Also if you look up the earth's radius on wikipedia, it says 6,371km which is close to 6,380km.
Audra is looking at a diagram of an oxygen atom. Which particle(s) does she see inside the nucleus?
plz help this is like 30% of my grade :)
Answer:
C: protons and electrons are found in the nucleus.
Step-by-step explanation:
Ok! So all atoms are composed of three basic things, protons, neutrons, and electrons. There are two parts of an atom, the nucleus and the electron cloud that surrounds the nucleus. In the nucleus are the protons and neutrons, and in the electron cloud are the electrons. Therefore, the answer would be C: protons and electrons are found in the nucleus.
Protons and electrons are found in the nucleus. The correct option is C.
What are protons and electrons?A subatomic particle with a negative charge is an electron. A subatomic particle having a positive charge is called a proton. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. A type of subatomic particle without charge is the neutron (they are neutral).
All atoms are composed of three basic things, protons, neutrons, and electrons. There are two parts of an atom, the nucleus and the electron cloud that surrounds the nucleus. In the nucleus are the protons and neutrons, and in the electron cloud are the electrons.
Therefore, the answer would be C: protons and electrons are found in the nucleus.

Make a conjecture about the diagram below. Is AC greater than, less than, or equal to BC? Explain your reasoning.
Triangle A C B is sitting on horizontal line X Y. Points A and B of the triangle are on the line. Angle C B Y is 90 degrees.
Answer:
AC is greater than BC because segment AC is the hypotenuse of right triangle ABC, and the hypotenuse is the longest side of a right triangle.
The hypotenuse is the longest side of the triangle. Side AC of the triangle is its hypotenuse, thus greater than BC (segment and angle theorem of a triangle).
A triangle is a shape with three side and angles. Its longest side is referred to as hypotenuse. And this side is usually opposite to the greatest angle. Examples of triangle include: equilateral, isosceles, acute, right angles, obtuse angle etc.
The given question shows that triangle ACB is a right angled triangle. This is because <CBY = [tex]90^{o}[/tex].
So that;
<CBY + <CBA = [tex]180^{o}[/tex]
Now comparing side AC with BC:
The segment and angle theorem of a triangle states that: the longest side of a triangle is always opposite to the greatest angle.
Thus, since <CBA is the greatest of the angles here, then AC is the longest side.
Therefore, the side AC is the hypotenuse of the triangle and it is greater than BC.

A secret recipe requires you mix chocolate and cream cheese in the ratio 3:2, based on weight. If you use 21 oz of chocolate, how much cream cheese do you need?
Answer: 14 oz
Step-by-step explanation:
CH/CR 3:2
3x/3=21/3
x=7
2*7=14 oz.
If you use 21 oz of chocolate, 14 oz cream cheese is needed.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
You can compare any two amounts that have the same units.
Given:
ratio of chocolate and cream cheese = 3:2
let the common ratio be x
Chocolate= 3x and Cream cheese = 2x
So, 21 oz of chocolate used
3x=21
x- 21/3

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary of $625 per week. How much did she earn last week if she sold $4,500 in electronics merchandise? Round your intermediate calculations and answer to the nearest cent.
Answer:
She earned 1,076 dollars and 25 cents.
Step-by-step explanation:
x = 7.25 * 4,500 / 100
x = 7.25 * 45
x = 326.25
So commission earned is 326.25 $
We need to add this to her base salary for the week, so:
750 + 326.25 = 1, 076.25
