Math problem: Mara spent 3/5 of her vacation in British Columbia. While in that province, she spent ½ of her time in Vancouver. What fraction of her vacation did Michaela spend in Vancouver? If her vacation lasted 20 days, how many days did she spend in Vancouver?
What equation can be used?
Answer:
[tex]f(x)=89x+1800[/tex]
Step-by-step explanation:
$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total
$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:
[tex]f(x)=89x+1800[/tex]

Answer:
-2.17 and -7.83
Step-by-step explanation:
[tex]4(x+5)^2=32[/tex]
Divide both sides by 4:
[tex](x+5)^2=8[/tex]
Take the square root of both sides:
[tex]x+5=\pm 2\sqrt{2}[/tex]
Subtract 5 from both sides:
[tex]x=-5\pm 2\sqrt{2}\approx -2.17, -7.83[/tex]
Hope this helps!
Answer:
-92(I think I am wrong, now that I think of it.)
Step-by-step explanation:
4(x+5)^2= 32= 4x+20^2= 32= 4x+400= 32= 4x= -368= -92
20^2= 400
32-400= -368
-368/4= -92

Answer:
Θ = 0, π, [tex]\frac{7\pi }{6}[/tex], [tex]\frac{11\pi }{6}[/tex]
Step-by-step explanation:
Using the identity
cos2Θ = 1 - 2sin²Θ, then
sinΘ + 1 = 1 - 2sin²Θ ( subtract 1 - 2sin²Θ from both sides )
2sin²Θ + sinΘ = 0 ← factor out sinΘ from each term
sinΘ(2sinΘ + 1) = 0
Equate each factor to zero and solve for Θ
sinΘ = 0, hence
Θ = [tex]sin^{-1}[/tex] (0) = 0, π, 2π
2sinΘ + 1 = 0 → sinΘ = - [tex]\frac{1}{2}[/tex] , thus
Θ = [tex]sin^{-1}[/tex] ( - [tex]\frac{1}{2}[/tex] ) = - [tex]\frac{\pi }{6}[/tex]
Since sinΘ < 0 then Θ is in third/ fourth quadrants, thus
Θ = π + [tex]\frac{\pi }{6}[/tex] = [tex]\frac{7\pi }{6}[/tex] or Θ = 2π - [tex]\frac{\pi }{6}[/tex] = [tex]\frac{11\pi }{6}[/tex]
Solution is
Θ = 0, π, [tex]\frac{7\pi }{6}[/tex], [tex]\frac{11\pi }{6}[/tex] for 0 ≤ Θ < 2π

A termis supply store pays a wholesaler $40 for a tennis racquet and marks it up by 60%.
What do they charge for the tennis racquet?
Answer:
$64
Step-by-step explanation:
Since the store buys the racket for $40 then marks it up, the store is selling it for 160% of the wholesale price. X is the price we are looking for - the price after it was marked up.
40 / x = 100/160
(40/x) * x = (100/160) * x
40 = 0.625 * x
40/0.625 = x
64 = x
x = 64

What number is shown by the model?
A. 28
B. 2080
C. 208
o
D. 280
Answer:
280
Step-by-step explanation:
each of those squares are 100 and each bar is 10
add up the squares and you have 200
add up the bars and you have 80
add 200 and 80 and you have your answer. 280
Answer:
D
Step-by-step explanation:
Well, the bars, if you count them are ten for each column.
There are 8 bars on the right, so that is 280 - 80 = 200
There are two squares that are ten by ten, so that is 200 - 100 * 2 = 0
Find the area of the figure.
A rectangle with length 3 1/4 ft and width 2 1/2 ft
The area equals ____ ft2.
So the right answer is 8 1/8 ft^2.
look at the attached picture
Hope it will help you..
Good luck on your assignment..
Answer:
8 1/8 ft^2
Step-by-step explanation:
The area of a rectangle is found by
A = l*w
A = 3 1/4 * 2 1/2
Change to improper fractions
3 1/4 = (4*3+1)/4 = 13/4
2 1/2 = (2*2+1)/2 = 5/2
A = 13/4 * 5/2 = 65/8
Changing back to a mixed number
8 goes into 65 8 times (8*8=64) with 1 left over
65/8 = 8 1/8 ft^2

-7+ 5Y = -37 simplify your answer as much as possible
Answer:
y = -6
Step-by-step explanation:
To simplify this equation as much as possible, we have to get the variable y by itself.
To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.
-7 + 7 + 5y = -37 + 7
The 7s cancel out on the left side because -7+7 = 0 and so we are left with,
5y = -30
Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.
5y/5 = -30/5
y = -6

Find a polynomial function with the zeros -2, 3, 5 whose graph passes through the point (6,48)
Answer:
f(x) = 2x³ - 12x² - 2x + 60
Step-by-step explanation:
Given that the zeros are x = - 2, x = 3, x = 5 , then the factors are
(x + 2), (x - 3), (x - 5)
The polynomial is then the product of the factors, that is
f(x) = a(x + 2)(x - 3)(x - 5) ← a is a multiplier
To find a substitute (6, 48) into the polynomial
48 = a(8)(3)(1) = 24a ( divide both sides by 24 )
a = 2 , thus
f(x) = 2(x + 2)(x - 3)(x - 5) ← expand the last 2 factors using FOIL
= 2(x + 2)(x² - 8x + 15) ← distribute the parenthesis
= 2(x³ - 8x² + 15x + 2x² - 16x + 30)
= 2(x³ - 6x² - x + 30) ← distribute by 2
= 2x³ - 12x² - 2x + 60
Using the factor theorem, it is found that the polynomial function is given by:
[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]
-----------------------------
Factor theorem:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
-----------------------------
Zeros of -2, 3 and 5 mean that [tex]x_1 = -2, x_2 = 3, x_3 = 5[/tex]The polynomial is given by:
[tex]p(x) = a(x - x_1)(x - x_2)(x-x_3)[/tex]
[tex]p(x) = a(x - (-2))(x - 3)(x - 5)[/tex]
[tex]p(x) = a(x + 2)(x - 3)(x - 5)[/tex]
[tex]p(x) = a(x^2 - x - 6)(x - 5)[/tex]
[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]
-----------------------------
It passes through the point (6,48), thus when [tex]x = 6, p(x) = 48[/tex].This is used to find the leading coefficient.[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]
[tex]48 = a(6^3 - 6(6)^2 - (6) + 30)[/tex]
[tex]24a = 48[/tex]
[tex]a = \frac{48}{24}[/tex]
[tex]a = 2[/tex]
Thus, the polynomial is given by:
[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]

Joey sells cars at Orange City Ford. He earns $350 a week plus $200 per car he sells. If he earned $1550 last week, how many cars did he sell? Write an equation and solve. PLSHURRY
Answer:
Joey sold 6 cars
Step-by-step explanation:
Joey earns $350 per week + $200 per car he sells
The number of cars that he sold last week is unknown, so represent it with a variable, x.
Write an equation
$350 + $200x = $1,550
Subtract $350 from both sides of this equation
$200x = $1200
Divide both sides of the equation by 200
x = 6
Joey sold 6 cars

Is area the same as surface area?
Answer:
Area is almost the same as surface area. However, surface area is more complicated, and you have to split the object that you are measuring into different parts to get their area before you can find the whole surface area.
Step-by-step explanation:
(I hope this helped you)
Answer: No, it is not
Step-by-step explanation:
AREA DEFINITION: Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width.
SURFACE AREA DEFINITION: The surface area is the sum of the areas of all six sides. To find the area of adjacent sides (Width x Height) x 2 sides. Find the area of ends (Length x Width) x 2 ends. Add the three areas together to find the surface area.

Answer:
The variable is the main part, it is the base of the whole thing
The variable is the main part, it is the base of the whole thing that shows all the critical points for the inequality ? , x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2.
How do you find the critical points of an inequality?Solve a rational inequality.
Determine the critical points–the points where the rational expression will be zero or undefined. Use the critical points to divide the number line into intervals. Test a value in each interval. Above the number, the line shows the sign of each factor of the rational expression in each interval.
How do you find the critical points of a function?To find the critical points of a function y = f(x), just find x-values where the derivative f'(x) = 0 and also the x-values where f'(x) is not defined. These would give the x-values of the critical points and substituting each of them in y = f(x) will give the y-values of the critical points.

The product of two rational numbers is ______ rational.
The product of two rational numbers is always rational
Proof:
Let a = p/q and b = r/s be two rational numbers. We will have p,q,r,s be integers where denominators q and s are nonzero. We cannot divide by zero.
Multiplying a and b gives
a*b = (p/q)*(r/s) = (p*r)/(q*s)
Due to the closure property of integer multiplication, the expressions p*r and q*s are integers. The result we get is in the form of integer/integer. Basically we have two integers being divided. Furthermore, q*s is nonzero as neither q nor s is zero.
Therefore, if a and b are rational, then a*b is also rational as well.
