Answer:
1 million scooters
Step-by-step explanation:
We are told that the profit (in millions of dollars) for a producer of electric scooters can be modeled by P = -x³ + 7x where x is the number of scooters produced (in millions).
We are told that currently the company produces 2 millions scooters and makes a profit of $6,000,000.
Thus, the profit equation is;
6 = -x³ + 7x
x³ - 7x + 6 = 0
We are given 2 as a root.
Let's try 1.
1³ - 7(1) + 6 = 0
0 = 0
So 1 is a root.
Thus, the lesser number of scooters the company could produce and still yield the same profit is 1 million scooters

If Serena puts $1000 in a savings account that pays 2% interest compounded annualy, how much money will she have in the account after 10 years? (Hint: To find the amount of money after 1 year. multiply by 1.02.)
Answer:
5000
Step-by-step explanation:
1000 ÷ 2 = 500 x 10 = 5000
Answer:
$1221.19Step-by-step explanation:
Formula for compound interest:
A= P(1+r/n)^n x t
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
We know that Serena pays annually meaning yearly (12 months or 1 year)
So after substituting all the numbers in,
A= 1000(1+0.02/12)^(12x10)
We change the rate to 0.02 because we must divide 2% by 100%. And divide the rate by number of times applied per time (n).
DISCLAIMER:
I have not done compound interest questions in a long time but if you want to confirm my answer, go to a calculator site and just input the numbers on there.

Answer:
3y - x = 21
Step-by-step explanation:
Answer:
3y - x = 21
Step-by-step explanation:
y = -3x - 8
The perpendicular line has the reciprocal slope.
So, the slope of this perpendicular line would be 1/3.
The equation that has the slope of 1/3 is 3y - x = 21.

Bailey can put x houses of his holiday miniature village on each of 7 shelves. He also has 10 houses displayed on his buffet. If he wants to display at least 45 of his houses, how many houses must he put on each of the 7 shelves? Write an inequality to represent this situation
Answer:
7x + 10 ≥ 45
Step-by-step explanation:
Given that:
Number of shelves = 7
Number of houses to display on each shelf = x
Number of houses to display = atleast 45 (≥)
Number displayed on buffet = 10
Number displayed on buffet + (number of shelves * number per shelf) ≥ number of houses to display
10 + (7 * x) ≥ 45
7x + 10 ≥ 45
find the measurement of the angle? will give brainliest
Answer:
98°
Step-by-step explanation:
The two base angles of a parallelogram are always equal and likewise for the two other angles which makes the base 164° combined an 360-164=196° and 196°/2=98°
a._x2 _ 25
How do you do this
Answer:
x=[tex]\frac{+}[/tex]5 or x=5, x=-5
Step-by-step explanation:
If the question is [tex]x^{2}=25[/tex] then you take the square root of both sides. [tex]\sqrt{x^{2}}=\sqrt{5^{2}}[/tex] because 25=5*5=[tex]5^{2}[/tex].
When you simplify you get x=[tex]\frac{+}[/tex]5
So x=-5, =5.
Figure A is a scale image of figure B. What is the value of x?
Answer:
The value of x = 20.
Step-by-step explanation:
Figure B is the scale image of A.
It is clear that:
side 10 of figure A has the image side of 12.5 in figure B.which can be obtained by multiplying 10 with 1.25
i.e.
10*1.25=12.5so the side 16 of figure A must have to be multiplied by 1.25 to get the image the figure B.
so
16*1.25=20Therefore, the value of x = 20.

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
x° + 104° + 32° = 180°
Step 2: Solve for x
Combine like terms: x + 136 = 180Subtract 136 on both sides: x = 44°Answer:
44°
Step-by-step explanation:
Because Sum of three angles of a triangle equals 180 °
So 180°-(104°+32°)
=180°-72°
=44°

What is the equation of the vertical line through (-8, 5)
Answer:
The equation of the vertical line passing through the point (-8, 5) will be:
[tex]x=-8[/tex]Step-by-step explanation:
As we have to determine the equations for the horizontal and vertical lines passing through the point (-8, 5).
To determine the equation for the vertical line passing through the point (-8, 5), we must observe that the vertical line will always have the same x-value regardless of y-values.
Therefore, the equation of the vertical line passing through the point (-8, 5) will be:
[tex]x=-8[/tex]Y: 2y - 3(4y-3) = 9y + 28
Answer:
y = - 1
Step-by-step explanation:
Given
2y - 3(4y - 3) = 9y + 28 ← distribute and simplify left side
2y - 12y + 9 = 9y + 28
- 10y + 9 = 9y + 28 ( subtract 9y from both sides )
- 19y + 9 = 28 ( subtract 9 from both sides )
- 19y = 19 ( divide both sides by - 19 )
y = - 1

the first term in a sequence is 3. the term to term rule is add 5. is 97 at term in the sequence? give a reason why.
I'm kind of on a time crunch so please help ASAP. Thank Youuu x
Answer: No it’s not.
Step-by-step explanation: So if to find the next number, you add five, then all of the numbers in the sequence will either end with 8 or 3. (5+3 or 0+3). Therefore 97 is not a term in the sequence.
how do i find the value of x?
Answer:
x = 18 (verified by algebra) ✅Step-by-step explanation:
When we have two similar triangles, we can use a proportion to determine an unknown value.
[tex]\frac{2x + 80}{87} = \frac{80}{60}[/tex]
We will cross multiply to get two equivalent equations that can be solved.
(2x + 80) x 60 = 120x + 4800
We can simplify this by dividing both sides by 24 to get a much simpler equation to work with: 5x + 200.
80 x 87 = 6960
We will also divide this by 24. The answer is 290
5x + 200 = 290
Subtract 200
5x = 90
Divide by 5
x = 18
Now, we can also check to make sure we did everything correctly.
(2(18) + 80) x 60 = 120x + 4800
(36 + 80) x 60 = 120(18) + 4800
116 x 60 = 2160 + 4800
6960 = 6960 ✅

Tom rented a truck for one day. There was a base fee of $14.95, and there was an additional charge of 73 cents for each mile driven. Tom had to pay $220.81 when he returned the truck. For how many miles did he drive the truck?
Answer:
Tom drove 282 miles.
Step-by-step explanation:
x = number of miles driven
220.81 = 14.95 + 0.73x
-14.95 -14.93
205.86 = 0.73x
/0.73 /0.73
282 = x
