Step-by-step B. is your answer
explanation:
y = x^3 + 5x^2 + 3x x= -3
Answer:
9
Step-by-step explanation:
-3^3 +5*(3)^2 +3*-3
-27+5*9+(-9)
-27+45-9
=9
Answer:
Step-by-step explanation:
Wherever you see an x, put in -3
y=(-3)^3 + 5(-3)^2 + 3(-3)
y = - 27 + 5 * 9 + -9
y = -27 + 45 - 9
y = 9

2. A local t-shirt company sold 2000 t-shirts two weeks ago when they charged $10 for each shirt. The following week they sold 1120 t-shirts when they raised the price to $19 per shirt. Assuming that this rate of change continues find the following: a. Find a linear function S(p) that models the number of shirts sold as a function of the price p. b. Explain the meaning of the slope In terms of the problem. c. Predict the number of shirts the store would sell if they charged $25 for each shirt. d. If the store would like to maintain a weekly sales level of 1450 shirts how much should they charge per shirt?
9514 1404 393
Answer:
a) S(p) = -97.78p +2977.78
b) about 98 fewer shirts per week will be sold for each $1 increase in price
c) 533 shirts per week
d) $15.63
Step-by-step explanation:
a) You are given two ordered pairs: (p, s) = (10, 2000) and (19, 1120). The two-point form of the equation for a line can be used.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
s = (1120 -2000)/(19 -10)(p -10) +2000
s = -97.78(p -10) +2000
S(p) = -97.78p +2977.78
__
b) The slope is shirts/dollar, meaning about 98 fewer shirts will be sold for each dollar increase in price.
__
c) S(25) ≈ 533
At a price of $25, the store would sell about 533 shirts per week.
__
d) 1450 = S(p) = -97.78p +2977.78
-1527.78 = -97.78p
15.625 = p ≈ 15.63
The store should charge $15.63 per shirt to maintain sales of 1450 shirts per week.
What is equivalent to 0 = 2x2 - 16x – 18 when completing the
square?
Answer:
x = 1
x = -9
Step-by-step explanation:
(2x2 + 16x) - 18 = 0
2x2 + 16x - 18 = 2 • (x2 + 8x - 9)
x2 + 8x - 9
-9 + 1 = -8
-3 + 3 = 0
-1 + 9 = 8
2 • (x + 9) • (x - 1) = 0
2 = 0
x+9 = 0
x = -9
x-1 = 0
x = 1
x2 + 8x - 9 = 0
x2+8x = 9
(x+4) • (x+4) =
(x+4)2
x2+8x+16 = 25 and
x2+8x+16 = (x+4)2
(x+4)2 = 25
x = -4 + √ 25
x2 + 8x - 9 = 0
has two solutions:
x = -4 + √ 25
or
x = -4 - √ 25
- B ± √ B2-4AC
x = ————————

A = 1
B = 8
C = -9

-8 ± √ 100
x = —————

x = ( -8 ± 10) / 2
x =(-8+√100)/2=-4+5= 1.000
or:
x =(-8-√100)/2=-4-5= -9.000
Answer: x = 1
x = -9

What is the error in this equation for a trigonometric ratio? Explain the error in full sentences and give a corrected ratio. (5 points)
Answer:
[tex]\cos\ A = \frac{2}{4.5}[/tex]
Step-by-step explanation:
Given
[tex]sin\ A = \frac{2}{4.5}[/tex]
See attachment
Required
Explain and correct the error
The error in the equation is that: the formula of cosine of angle A is used to calculate the sine of angle A.
The ratio can be corrected as by using:
[tex]\cos\ A = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos\ A = \frac{AC}{AB}[/tex]
[tex]\cos\ A = \frac{2}{4.5}[/tex]

Answer:
y=5/2x+2
Step-by-step explanation:
To get the slope,
(-5-0) /(0-2)=-5/-2=5/2
Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way
(0,2)(x,y)
y-2/x-0=5/2
Cross multiplication,2(y-2)=5(x-0)
2y-4=5x-0
2y=5x-0+4
2y=5x +4
Divide both sides by 2 to get
y=5/2x+2.

Ky wants to buy three shirts, which were originally priced at $49.96 each. The store will discount the price of the 3rd shirt by 50% off and apply a %7.1 tax to the total cost of all three shirts. Including the tax, what will be the mean cost of each shirt?
9514 1404 393
Answer:
$44.49
Step-by-step explanation:
The total cost before tax will be ...
$49.96 +49.96 + 0.50(49.96) = $124.90
With tax added, the cost is ...
$124.90 × 1.071 = $133.77
Then the average cost per shirt for the 3 shirts is ...
$133.77/3 = $44.59
The mean cost of a shirt is $44.59.
Answer:
the answer is $44.49

There are 4 classrooms for fifth grade and 4 classrooms for sixth grade at a school. Each classroom has 20 students. A teacher is planning a field trip for some fifth and sixth grade students at this school. The teacher knows the following information:
90% of fifth and sixth grade students have permission to go on the trip.
4 teachers are going on the trip.
The school requires 1 parent volunteer for every 8 students going on the trip.
Part A
How many parent volunteers are needed to go on the trip?
Answer:
18
Step-by-step explanation:
Fifth grade has 80 students and sixth grade has 80 students. so if you get 90% of both then you have 72 and 72. Add and divide by 8 and you have the answer of 18 parent volunteers going.

can someone teach me how this goes? geometry , inscribed angles but circles
Answer:
60
Step-by-step explanation:
So basically all you need to know for this one is that when there is an inscribed angle, the angle measure is 1/2 of the measure of the arc for that angle.
That might sound confusing, but an example from the picture is that angle ABC will be half of arc AC. This means that angle ABC is 1/2 of 120 = 60 degrees.
The answer is 60 degrees.
