Answer:
3^4, or you could say three to the fourth power.
An exponent is a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression. 3 x 3 x 3 x 3 is equivalent to 3^4 because you are multiplying three four times.
*Warning: 3 x 3 x 3 x 3 is NOT 3 x 4!!!*
Write an equation of the line that passes through the given points.
(2,6) (-4,-2)
Answer:
y = 8/6x + 10/3
Step-by-step explanation:
You find the slope (m) first which is
Change of y over change of x
(6) - (-2) over (2)- (-4)
8/6 = m
Then you plug it into the equation y = mx + b
y = (8/6)x + b
Now you pick any of the set of points to plug in for x and y to solve for b
(6) = (8/6)(2) + b
6 = 8/3 + b
b = 10/3
Then plug into the equation for just m and b to get the equation of the line that passes thru both sets of points.
y = 8/6x + 10/3
Ava's family has completed 40% of their road trip. They have traveled 72 miles. How many miles is the trip?
Answer:
180 miles
Step-by-step explanation:
if you divide 72 by 4 you can see what 1/10 of the trip is, which is 18. 18 times 10 (since 18 is one tenth of it) equals 180. hope this helps!

A company rents out 16 food booths and 23 game booths at the county fair. The fee for a food booth is $100 plus $9 per day. The fee for a game booth is $95 plus $5 per dat. The fair lasts for d days, and all the booths are rented for the entire time. What is the simplified expression for the amount, in dollars, that the company is paid.
Answer:
3785 + 259d
Step-by-step explanation:
cost of food booths = 16 * (100 + 9d) = 1600 + 144d
cost of game booths = 23 * (95 + 5d) = 2185 + 115d
total = 1600 + 2185 + 144d + 115d = 3785 + 259d

A manufacture of spark plugs how's it going producing less than 2% affective ones. Of the last 8000 spark plugs, 13 were defective. a. What is the experimental probability that the next sparkplug will be defective? b. Did the manufacture reach his goal? Explain.
Answer:
P = 0.001625
yes, it did
Step-by-step explanation:
given data
affective ones = 2%
spark plugs = 8000
defective = 13
to find out
experimental probability that the next sparkplug will be defective and Did the mannufacturer reach its goal
solution
we know that there are 13 are defective out of 8000
so P = 13 ÷ 8000
P = 0.001625
so that P( the next sparkplug will be defective) is = 0.001625
and
yes, we mannufacturer to reach goal
because 0.001625 < .02
So, the goal is reached as the experimental probability is less than 2%
A customer paid 9x + 11y dollars for a bag that contains x pounds of chocolate and y pounds of almonds.
Which statements about the expression are true?
Select the three statements that are true.
The amount the customer paid, in dollars, for the chocolate in the bag is 9x.
O The amount the customer paid, in dollars, for the chocolate in the bag is 11y.
The total weight of the bag of chocolate and almonds is 9x + 11y.
The total weight of the bag of chocolate and almonds is x + y.
The cost per pound of the chocolate is $11.
The cost per pound of the almonds is $11.
Answer:
*The amount the customer paid, in dollars, for the chocolate in the bag is 9x.
*The total weight of the bag of chocolate and almonds is x + y.
*The cost per pound of the almonds is $11.
Step-by-step explanation:
A customer paid 9x + 11y dollars for a bag that contains x pounds of chocolate and y pounds of almonds.
From the above questions, we know that:
The weight of Chocolate = x pounds
The weight of Almonds = y pounds
The cost per Chocolate = $9
The cost per Almonds = $11
Therefore, the three statements that are true are:
* The amount the customer paid, in dollars, for the chocolate in the bag is 9x.
* The total weight of the bag of chocolate and almonds is x + y.
*The cost per pound of the almonds is $11.
Item 6 A rectangular prism has a length of 8 meters, a width of 4 meters, and a height of 5 meters. Which equations could be used to determine the volume, V, of the prism? Select each correct answer. V = 12 × 5 V = 5 × 4 × 4 V = 8 × 4 × 5 V = 32 × 5
Answer:
I am 100% sure that the answer is 240.
Step-by-step explanation:
The volume of the prism is 160 m³ and the correct equation is V = 8 × 4 × 5.
How to write a linear equation?A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.
The length, width and height of the rectangular prism are given as 8m, 4m and 5m respectively.
Since, the volume of the prism is given as the product of its length, width and sides.
For the given prism the volume can be obtained as,
V = 8 × 4 × 5
⇒ V = 160 m³
Hence, the correct equation is given as V = 8 × 4 × 5.

Answer:
34.06°
Step-by-step explanation:
25 is the length of the hypotenuse side and 14 is the length of the opposite side.
Therefore, you will need to use sine to work out the missing angle.
sinx = opp / hyp
sinx = 14 / 25
x = sin ^ -1 (14 / 25)
= 34.06°
What are four ways to represent functions?
A function shows the relationship between at least two variables. There are several ways to represent a function; some of them are:
Using tablesUsing equationsUsing graphsBy verbal expressionsTables
The following table shows the relationship between two variables x and y
[tex]\left[\begin{array}{cccccc}x&1&2&3&4&5\\y&2&4&6&8&10\end{array}\right][/tex]
Equations
Notice that the y values of the above table are twice the corresponding x-values.
So, the equation can be represented as:
[tex]y = 2x[/tex]
Graphs
See attachment for the graph of [tex]y = 2x[/tex]

What is the equation of the line perpendicular to y = = x+ 3 passing through the point (-3,4)?
Answer:
y = 3x + b
Step-by-step explanation:
The slope of y=mx+3 that passes through (-3,4) is found like this:
1. Substitute the y and x values in (4 = m*(-3) + 3).
2. Simplify by subtracting 3 from each side (1 = m*(-3)).
3. Simplify by dividing each side by -3 (-1/3 = m).
Since the slope of perpendicular lines are negative reciprocals, the slope of the perpendicular line is 3. The y-intercept can be anything and it will still be perpendicular.

Answer:
Step 1, all the exponents are increased by 4
Step-by-step explanation:
The first incorrect step occurred in Step 1, where all the exponents were increased by 4.
This is mathematically incorrect due to exponential rules. When distributing exponents inside parentheses, we have to multiply the existing exponents inside the parentheses by the exponent outside the parentheses.
For example, (x²)³ is not x²⁺³, but rather, x⁽²⁾⁽³⁾.
We multiply the exponents instead of adding them together.
Therefore, the correct Step 1 should multiply all the variables' exponents by 4.
Steps 2 and 3 are correct since we do add the exponents when multiplying exponents with the same base, and we do subtract exponents with the same base when dividing.
