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

Answer:
F.
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.
Find the height of an equilateral triangle with sides of length 12
Answer:
Answer
sqrt(108)
6 sqrt(3)
10.3923
I don't know which answer you want.
Step-by-step explanation:
Drop a perpendicular from the top angle to the base. The base is cut into 2 equal parts.Each part is 12/2 = 6The perpendicular, as its name implies, meets the base at 90o.You can use the Pythagorean Theorem to find the height.h^2 = side^2 - (1/2 b)^2
h^2 = 12^2 - 6^2
h^2 = 144 - 36
h^2 = 108
Take the square root of both sides
h = sqrt(108)
h = sqrt(2*2 * 3 * 3 * 3)
h = 2 * 3 sqrt(3)
h = 6sqrt(3)
h = 6 * 1.7321
h = 10.3923

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

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

Step-by-step explanation:
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

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

The population of a city increases by 3.1% per year. If this year's population is 119,000, what will next year's population be, to the nearest individual?
- I just honestly don't know where to start. I haven't done percents in a while, so I need to jog my memories. Any advice on where to start?
Answer:
The next year population is 122,689
Step-by-step explanation:
The computation of the next year population is as follows:
= This year population × increase percentage
= 119,000 × (1 + 0.031)
= 119,000 × 1.031
= 122,689
Hence, the next year population is 122,689
The above formula is applied so that the correct value of the population could come
and the same is relevant

The cross section of a water bin is shaped like a trapezoid. The bases a a trapezoid are 20 feet and 6 feet long. It has a area of 39 square feet. What is the height of the cross section?
Answer:
the height of the cross section is 3 feet
Step-by-step explanation:
The computation of the height of the cross section is shown below:
Area = 1 ÷ 2 × (a + b) × h
39 = 1 ÷ 2 × (20 + 6) × h
39 = 1 ÷2 × 26 × h
39 = 26 ÷ 2 × h
39 = 13 × h
h = 39 ÷ 13
= 3 feet
hence, the height of the cross section is 3 feet

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
