Answer:
80 ; 204 ; undefined ; 400 ; 0 ; 200 ; 320
Step-by-step explanation:
C(x) =(.80x, for 0 500 )
Find the value of :
C(100) = 0.80*(100) = 80
C(255) = 0.80 * 255 = 204
C(550) = undefined
C(500) = 0.80 * 500 = 400
C(O) = 0.80 * 0 = 0
C(250) = 0.80 * 250 = 200
C(400) = 0.80 * 400 = 320

If the sin 30º = 1/2
then which statement is true? (6 points)
a. cos 150° = 0, because the cosine and sine are supplements
b. cos 60° = 0, because the cosine and sine are complements
c. cos 150° = 1, because the cosine and sine are supplements
d. cos 60° = 1/2, because the cosine and sine are complements
Because sine and cosine are complements, we will have that:
cos(60°) = 1/2.
Which statement is true?First, because cosine and sine are complements, we know that:
cos(x) = sin(x + 90°).
cos(90° - x) = sin(x).
We will use the second relation, with x = 30° we can write:
cos(90° - 30°) = sin(30°)
cos(60°) = sin(30°)
And we know that sin(30°) = 1/2
Then we also have cos(60°) = 1/2.
So the correct option is d.

hello, can i please have help on this question.thank you
Answer:
y = 4x - 3
Step-by-step explanation:
The equation for a line is y = mx +c
We need to find m which is the gradient:
To do this pick any two coordinates on the line:
(1, 1) and (2, 5)
Next divide the difference of the y coordinates by the difference of the x coordinates:
5 - 1 / 2 - 1
= 4/1 = 4
so our gradient is 4
We'd write that as y = 4x + c
Next we need to find c which is the y-intercept
To do this just simply look for where the line crosses the y-axis
This is -3
So we'd write that as y = 4x - 3

6x + 6y=-6
5x + y=-13
Answer:
(-3, 2)
x=-3, y=2
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation. and thats how you get your answer :)
The value of x is -3 and value of y is 2.
The given equations are:
6x + 6y=-6 ..(1)
5x + y=-13...(2)
From equation (2)
y=-13+5x..(3)
Plug in equation in equation (1):
6x + 6(-13+5x)=-6
6x-78+30x=-6
24x=-72
Divide both sides by 24:
x=-72/24
x=-3
Now put x=-3 in equation (2):
5(-3) + y = -13
-15 + y = -13
y = -13 + 15
y = 2
Hence, the value of x is -3 and value of y is 2.

Aubrey has a new art box in the shape of a rectangular rectangular prism. The box is 12 cm space, by 20cm, 5 cm the only thing in the art box is a new pink eraser with the dimensions shown below. What is the volume of the art box not taken up by the eraser?
Answer:
By an online search, I've found that the dimensions of the eraser are:
4cm by 2cm by 0.5cm
First, we need to remember that for a rectangular prism of length L, width W, and height H, the volume is:
V = L*W*H
We know that the measures of the box are:
12cm by 20cm by 5cm
Then we can define:
L = 12cm
W = 20cm
H = 5cm
Then the total volume of the box is:
V = 12cm*20cm*5cm = 1200 cm^3
For the eraser, we will have:
L = 4cm
W = 2cm
H = 0.5cm
Then the volume of the eraser is:
v = 4cm*2cm*0.5cm = 4 cm^3
The volume of the box that is not taken up by the eraser is equal to the difference between the volume of the box and the volume of the eraser.
Then:
Volume not taken by the eraser = V - v = 1200cm^3 - 4cm^3 = 1196cm^3
In this diagram, the measure of
Answer:
2x - 60 = 180
Step-by-step explanation:
Angles RQS and PQS form a linear pair, so they are supplementary.
The sum of their measure is 180°.
Both angle measures are unknow, so let's use x for the measure of <PQS.
The measure of angle RQS is 60° less than the measure of <RQS, so it is
x - 60
Now we add the measures and set the sum equal to 180.
x + x - 60 = 180
Combine like terms on the left side.
2x - 60 = 180
Answer: 2x - 60 = 180

A)$112.50
B)$75.00
C)$50.00

Answer:
C) $50.00
Step-by-step explanation:
$7.50 is the 15% discount
1% of the original price would be ($7.50 / 15)=0.50

what is 3/8 divided by 4/5
The answer you are looking for is 15/32.
To find this answer, you must first find the Least Common Denominator. The least common denominator of these 2 fractions can be found by simply multiplying the 2 given denominators together. 5 * 8 = 40.
Now that you found the LCD, you can start to solve the equation. To get 40 as the denominator for 3/8, you multiply the fraction by 5/5.
3/8 * 5/5 = 15/40.
To get 40 as the denominator for 4/5, you multiply it by 8/8. 4/5 * 8/8 = 32/40.
Finally, you divide 15/40 by 32/40. The denominators cancel out, so the numerator becomes 15 and the denominator now becomes 32.
So your answer is 15/32 (which cannotbe simplified)

Find a quadratic polynomial with integer coefficients which has x = 2/9, ± SQRT23/9 as its real zeros.
Answer:
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].
Step-by-step explanation:
Statement is incorrectly written. Correct form is described below:
Find a quadratic polynomial with integer coefficients which has the following real zeros: [tex]x = \frac{2}{9}\pm \frac{\sqrt{23}}{9}[/tex].
Let be [tex]r_{1} = \frac{2}{9}+\frac{\sqrt{23}}{9}[/tex] and [tex]r_{2} = \frac{2}{9}-\frac{\sqrt{23}}{9}[/tex] roots of the quadratic function. By Algebra we know that:
[tex]y = (x-r_{1})\cdot (x-r_{2}) = x^{2}-(r_{1}+r_{2})\cdot x +r_{1}\cdot r_{2}[/tex] (1)
Then, the quadratic polynomial is:
[tex]y = x^{2}-\frac{4}{9}\cdot x -\frac{19}{81}[/tex]
[tex]y = 81\cdot x^{2}-36\cdot x -19[/tex]
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].
