A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out the maximum amount of profit the company can make, to the nearest dollar. y=-x^2+78x-543 y=−x 2 +78x−543
Answer:
978
Step-by-step explanation:
y= -x²+ 78x - 543
y= ax²+ bx + c
a= -1, b= 78, c= -543
max = c -(b²/4a)
= -543 -(78²/-4)
= -543 + 1521
= 978

A CD usually sells for $17.00. If the CD is 20% off, and sales tax is 6%, what is the total price of the CD, including tax?
A.
$14.42
B.
$15.32
C.
$13.52
D.
$14.62
Answer:
14.42
Step-by-step explanation:
17.00 x .80 20% off means price is 80% (or .80) of price
=13.6
13.6 x .06 = .82 sales tax
13.60 + .82 = 14.42 sales price plus sales tax
Multiply (a-b) by (2b-a).
Answer:
-2b(a) - a^2 -2b^2
Step-by-step explanation:
Just use the 'foil' method, meaning that you multiply the first number of one part (a), to the first and second to the next part (2b, -a)
Then, multiply the second number of that part (-b), to the first and to the next part (2b, -a)
You would get: -2b(a) - a^2 -2b^2
Multiplication is the process of multiplying. The multiplication of (a-b) by (2b-a) results in 3ab-a²-2b².
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
An expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context. The multiplication of the two given expressions (a-b) and (2b-a) can be done as shown below,
(a-b) × (2b-a)
= a(2b-a) -b(2b-a)
= (a × 2b) - (a × a) - (b × 2b) + (b × a)
= 2ab - a² - 2b² + ab
= -a² -2b² + 3ab
= 3ab -a² -2b²
Hence, the multiplication of (a-b) by (2b-a) results in 3ab-a²-2b².

Challenge: Jasmine needs 300 centimeters of fabric to make her new dress. The fabric costs $5 for each meter. How much will her fabric cost to make the dress?
Answer: $15
Step-by-step explanation:
Jasmine needs 300 centimeters
$5 each meter
The first step you need to do is convert 300 centimeters to meters, because it’s $5 for each meter.
(You can use the King Henry Chart to help you)
So, 1 centimeter is 1/100 meter
How much is 300 centimeters in meters?
300x1/100
= 300/100
=3
300 cm= 3m
Now, there is $5 for each meter.
How much does it cost for 3 meters?
= 5x3
= $15
It will cost her $15
The population of a coty is 100,000 and the annual growth rate is 4.2%. Write an equation to model the population y after x years
Answer: [tex]1,00,000(1+0.042)^x[/tex]
Step-by-step explanation:
Given
The initial population of a city is [tex]P_o=1,00,000[/tex]
The annual growth rate is [tex]4.2\%[/tex]
after 1 year it is
[tex]\Rightarrow P_1=1,00,000+4.2\%\times 1,00,000\\\Rightarrow P_1=1,00,000(1+0.042)[/tex]
after 2 years, it is
[tex]\Rightarrow 1,00,000(1+0.042)+4.2\%\times 1,00,000(1+0.042)\\\Rightarrow 1,00,000(1+0.042)^2[/tex]
after x years it is
[tex]\Rightarrow P_x=1,00,000(1+0.042)^x[/tex]

Use the equation s=5q+8 to find the value of s when q=1.
Answer:
s would equal 13
Step-by-step explanation:
Hello there!
So to find the value of s when q=1 we just have to plug in 1 into q into the expression s=5q+8
so when q=1
s=5(1)+8
5*1=5
5+8=13
so we can conclude that when q=1 s=13
Answer:
13
Step-by-step explanation:
s = 5q + 8
s = 5(1) + 8
s = 5 + 8
s = 13
how do i solve for x and y
4x+y=8
x=5-y
Puan Hamidah bought satay from a stall for her children. Her eldest and youngest children ate 1/6 and 0.25 of all the satay respectively. The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay. How many sticks of satay did her eldest child eat?
Answer:
12.01 sticks of satay
Step-by-step explanation:
Let
Total satay bought = x
Eldest child ate = 1/6x
Youngest child ate = 0.25x
Total = 1/6x + 0.25x
= 0.167x + 0.25x
= 0.417x
Remaining satay = x - 0.417x
= 0.583x
The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay.
Her and her other two children = 3 people
Sticks of satay pee person = 14
Total sticks eaten by 3 people = 14 × 3
= 42 sticks
0.583x = 42
x = 42/0.583
= 72.04
x = 72.04 sticks
Total satay bought = x = 72.04 sticks
Eldest child ate = 1/6x
= 1/6 * 72.04
= 12.01 sticks of satay

Answer:
$57
Step-by-step explanation:
→ Do 20% of $80
( 20 × 80 ) ÷ 100 = 16
→ Add 5 to the previous answer
5 + 16 = 21
→ Add 2 to 21
2 + 21 = 23
→ Minus 23 from the total price
80 - 23 = $57
The sum of two numbers is 26. The larger number is 5 more than twice the smaller. What are
the two numbers?
Answer:
Step-by-step explanation:
Let n = the smaller of the two numbers, and since the other number is 5 more than twice the smaller number n, then ...
Let 2n + 5 = the second and larger number.
Since the sum of the two unknown numbers is 26, then we can write the following equation to be solved for n as follows:
n + (2n + 5) = 26
n + 2n + 5 = 26
Collecting like-terms on the left, we get:
3n + 5 = 26
3n + 5 - 5 = 26 - 5
3n + 0 = 21
3n = 21
(3n)/3 = 21/3
(3/3)n = 21/3
(1)n = 7
n = 7
Therefore, ...
2n + 5 = 2(7) + 5
= 14 + 5
= 19
CHECK:
n + (2n + 5) = 26
7 + (19) = 26
7 + 19 = 26
26 = 26
Therefore, the two desired numbers whose sum is 26 are indeed 7 and 19.
Answer:
The answer is 7 and 19

Step-by-step explanation:
Everything has to be less than 4 which leaves us with C and F, but Fs dot is shaded in which means it is less than or equal to but it is only less than so it is F.
Answer:
F
Step-by-step explanation:
If you look x is less than 4 meaning that all values are lower than 4. We also know that 4 is not included due to the fact that the less than symbol doesn't have a line under it. F is the only line that meets all of the criteria.
y=-4x+2 solve for x and y how do i solve this problem
Answer:
y=-4x+2
and
x= y-2/-4
Step-by-step explanation:
you have y,
y= -4x+2
to solve for x, follow this...
y = -4 x + 2
-2 -2
y - 2 = -4 x
/-4 /-4
x= y-2/-4

TJ's Cat Food plans to use tins that are the shape of cylinders. Find the height of the tin, if its bottom diameter is 12 cm and volume is 757.36cm.
Answer:
6.69 cm
Step-by-step explanation:
Given data
Diameter= 12cm
Radius= 6cm
Volume= 757.36cm^3
The expression for the volume of a cylinder is
V= πr^2h
Substitute
757.36= 3.142*6^2*h
757.36=113.112h
h= 757.36/113.112
h= 6.69 cm

green
Step-by-step explanation:
Since we know that there is 8 clips (2+2+4) and then we take 4/8 as a decimal and we then get 0.125
Answer: 0.25
Step-by-step explanation: 2+4+2=8 8clios in the bag and 2 are green, so 2/8 is the probability it will be a green selected. 2/8 in decimal form is 0.25
