Answer:
-2/9 - (-2) = -2 2/9 :)
Step-by-step explanation:
Which values represent solutions to the equation?
Tangent (StartFraction 3 pi Over 4 EndFraction minus 2 x) = negative where x Is an element of [0, Pi]
The solution set for the given expression is {0, π/2, π}.
Which values of x are solutions for the given expression?Here we have the expression:
[tex]tan(\frac{3\pi}{4} -2x) = -1[/tex]
First, we know that:
[tex]tan(\frac{3\pi}{4}) = -1[/tex]
So, if x = 0, the equation is true, which means that x = 0 is a solution.
And the tangent function as a period of pi.
This means that:
tan(x) = tan(x - π) = tan(x - 2*π) etc.
Then if x = π/2 and x = π also are solutions, so we conclude that the solution set is:
{0, π/2, π}

Ann took a taxi home from the airport. The taxi fare was $2.10 per mile, and she gave the driver a tip of $5. Ann paid a total of $49.10.
Write an equation to determine the distance in miles (x) between the airport and Ann's home
Find the distance between the airport and Ann's home.
Answer:
$2.10x + 5= $49.10
x=21
Step-by-step explanation:
the x is used for a variable that changes and in this case the mph changes which lead x being the amount of miles that they had drove which at the end ends up multi. with the $2.10 . as for the 5 it was an initial as in it doesn't change.
for the second part
you subtract 5 from each side so you have the total of 2.10x= 44.10 then u divide 2.10 from each side and that will give you x = 21
Solve the system of equations and choose the correct answer from the list of options.
d + e = 15

9514 1404 393
Answer:
d. (10, 5)
Step-by-step explanation:
Add the two equations, and you get ...
2e = 10
e = 5
Solve the first one for d and you have ...
d = 15 -e
d = 15 -5 = 10
So, the solution is ...
(d, e) = (10, 5) . . . . . matches the last choice
_____
Check
d + e = 10 + 5 = 15
-d + e = -10 +5 = -5
The price that a company charged for a computer accessory is given by the equation 100-10x2 where x is the number of accessories that are produced, in millions. It costs the company $10 to make each accessory. The company currently produces 2 million accessories and makes a profit of 100 million dollars. What other number of accessories
produced yields approximately the same profit?
O 1.45 million
O 3.45 million
O 40 million
O 48 million
Answer: 1.45 million is your answer
Step-by-step explanation:
edge
The number of accessories produced that yields approximately the same profit as 2 million is 3.45 million. The correct option is B.
What is Revenue?
Revenue is defined as the money generated by normal business operations and is calculated by multiplying the average sales price by the number of items sold.
The profit (P) made by the company can be calculated as follows:
P = (Revenue) - (Costs)
Where Revenue = (Price per accessory) × (Number of accessories produced), and Costs = (Cost per accessory) × (Number of accessories produced).
So, using the given information, we can write:
P = (100-10x^2) x - (10x)
where x is the number of accessories produced in millions.
We know that the company makes a profit of 100 million dollars when it produces 2 million accessories, so we can set P = 100 and x = 2, and solve for the constant of proportionality k:
100 = (100-10(2)^2)(2) - (10)(2) + k
k = 200
Now, we can set P ≈ 100 again and solve for x, using k = 200:
100 = (100-10x^2)x - (10x) + 200
0 = -10x^3 + 10x^2 + 10x + 100
0 = -x^3 + x^2 + x + 10
We can solve this equation using synthetic division or by using a graphing calculator, and we find that there is a root between x = 3 and x = 4.
Therefore, the number of accessories produced that yields approximately the same profit as 2 million is 3.45 million, which is option B.

Find the distance between (-6,8) and (10,-4)
Answer:
use the distance formula you can find it on the net
The distance between (-6,8) and (10,-4) is 20 units.
What is the distance between two points ( p,q) and (x,y)?
The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
We are given that;
The points (-6,8) and (10,-4)
Now,
To use the formula, you need to plug in the values of x1, y1, x2 and y2 into the formula and simplify. For example, to find the distance between (-6,8) and (10,-4), you can do:
d = (10 - (-6))^2 + (-4 - 8)^2
d = (16)^2 + (-12)^2
d = 256 + 144
d = 400
d = sqrt(400)
d = 20
Therefore, the distance formula the answer will be 20 units.

A guppy was swimming 8 feet below the surface of the river. It swam down 6 more feet
to escape a large, hungry fish. What is the position of the guppy now relative to the
surface?
To solve the problem, Jenna subtracted 8 - 6 and came up with an answer of 2 feet. Is Jenna
correct? Why or why not?
Answer:No because once the guppy swam down 8 feet below the surface of the river the 8 is now negative since the surface of the ocean is 0 and 0-8=-8 and then he swam down 6 feet more so we have to subtract-8-6= -14 feet so the position of the guppy is now -14 feet below sea level.

Write multiplication expression to represent the change in temperature after the plane ascends 10,000 feet .... Above it says there is a 1.3°F drop in temperature for every thousand feet that an airplane climbs into the sky the temperature on the ground is -2.8°F... part b says what will the temperature b when the plane reach's an altitude of 10,000 feet
Answer:
1.3°F * 10 = 13°F
10.2°F
Step-by-step explanation:
Given that:
Temperature on the ground = - 2.8°F
Change in temperature per 1000 ft rise = 1.3°F
Change in temperature after the plane ascends 10000 ft
Change in temperature per 1000ft rise * (10000/1000)
1.3°F * 10 = 13°F
B.) Temperature at 10,000 feets
Temperature on ground + change in temperature at 10,000ft
-2.8°F + 13°F
= 10.2°F

model tire uses a scale in which 2 feet represents 3 inches. The actual tire used
to create the model tire has a diameter of 33 inches.
What is the diameter of the model tire on the shop's roof
Help plz!!! I need the work shown
Answer:
Ok, so this tire is 2 feet which is represented by 3 inches.
So, since the tire has a diameter of 33 inches, we multiply 33 by 3
33 times 3 is 99.
The diameter of the motel tire on the shop's roof is 99 inches.
