Answer:

Step-by-step explanation:
The value of the function at 870, the local maximum, is
= -0.02(870)2 + 34.80(870) - 4700
= -0.02(756900) + 30276 - 4700
= -15138 + 25576
= 10438
So the vertex is (870, 10438)
The cost t the company to produce 870 widgets is
C(870) = 4700 + 5.20(870) = 4700 + 4524 = 9224
So, the cost of the widgets plus the profit must be equal to the total sales, which is divided by the number of widgets reveal their individual price.
(10438 + 9224)/870 = 19662/870 = $22.60
P(x) = 7700
- 0.02x2 + 34.80x - 4700 = 7700
-0.02x2 + 34.80x -12400 = 0
x = {-34.80 ± √[(34.80)2 - 4(-0.02)(-12400)]}/2(-0.02)
x = [-34.80 ± √(1211.04 - 992)]/(-0.04)
x = (-34.80 ± √219.04)/(-0.04)
x = (-34.80 ± 14.8)/(-0.04)
x = 870 ± 370
so, $7700 in profits will be earned at either 500 widgets or 1240 widgets

8w-12=-4 anyone know the answer
Answer:
w=1
Step-by-step explanation:
8w-12=-4
8w =-4+12
8w=8
8w/8=8/8
w=1
Mark as brainliest
Answer:
Well first we have to know what -12 is -4. So I know that 8 subtracting 12 is -4 already but, i am explaining to your knowlege so here I go.
What we can do is add 12 to -4 and it will equal what _-12=-4
So -4+12=8
Since the variable is with 8, we have to find what the variable w is. So 8x_=8?
Thats obvious right? 8x1=8!
So 8w-12=-4 = 8x1=8-12=-4

Step A: Brian went to a trading-cards event. It cost $5 to enter and $4 for each card he
purchases. Write an equation that models his total cost for the day.
Step B: How many cards did Brian purchase if he spent a total of $29?
Step C: If Brian brought a total of $65, what is the maximum amount of cards he can purchase?
Explain why in a short paragraph and in your own words.
Answer:
Step-by-step explanation:
let x be the number of cards brian gets
let y be the amount of money he spends
the y intercept will be 5, since he automatically spends $5 to enter
a. 4x+5=y
b.29=4x+5 —-> 24=4x —-> x=6. Brian got 6 card
c. Brian can’t buy more than 15 cards. When you plug in 65 for y into the equation, after solving for x you get 15 To check, 4(15)+5=65

Cameron said that the Y intercept of a quadratic function always tells the maximum value of the function. explain Cameron's error
Answer:
We can have two cases.
A quadratic function where the leading coefficient is larger than zero, in this case the arms of the graph will open up, and it will continue forever, so the maximum in this case is infinite.
A quadratic function where the leading coefficient is negative. In this case the arms of the graph will open down, then the maximum of the quadratic function coincides with the vertex of the function.
Where for a generic function:
y(x) = a*x^2 + b*x + c
The vertex is at:
x = -a/2b
and the maximum value is:
y(-a/2b)
Jerry has just purchased his first home for $190,000. He put down a 20 percent down payment of $38,000 and took out a 5 percent mortgage for the rest. His mortgage payment is $700 per month. How much of his first monthly mortgage payment is amortization?
Answer:
$66.67
Step-by-step explanation:
The calculation of first monthly mortgage payment is amortization is given below:-
Amount borrowed = Purchase first home cost - Down payment
= $190,000 - $38,000
= $152,000
Annual interest = ($152,000 × 5%) ÷ 12
= $7,600 ÷ 12
= $633.33 per month
Now,
First monthly payment = Mortgage payment - Annual interest
= $700 - $633.33
= $66.67
Hence, we simply applied the above formula.

We can conclude that the line can be represented by the function; f(x) = -x/2 and slope = -1/2 where; x>= 0 due to the solid dot
For the line whose y-intercept is at point, (0, -2), and is plotted towards negative x; we have;
We can conclude the equation of the line can be represented by the function; f(x) = -x -2 where slope = -1, and domain; x < 0

2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
Answer:
There are 171 members in the club
Number of boys = 38
Number of girls = 133
Step-by-step explanation:
Let
x = total members of the club
Boys = 2/9x
if there are 95 more girls than boys
Girls = 2/9x + 95
how many girls are there in club?
Total members in the club = boys + girls
x = 2/9x + 2/9x + 95
x = 2+2/9x + 95
x = 4/9x + 95
x - 4/9x = 95
9x-4x/9 = 95
5/9x = 95
Divide both sides by 5/9
x = 95 ÷ 5/9
= 95 × 9/5
= 855/5
= 171
boys = 2/9x
= 2/9 * 171
= 342 / 9
= 38
Girls = 2/9x + 95
= 38 + 95
= 133
Total = 38 + 133
= 171
There are 171 members in the club
Number of boys = 38
Number of girls = 133

Write the equation of the line that passes through the given points. (8,0) and (0,4)
Answer:
[tex]y = - \frac{1}{2} x + 4[/tex]
Step-by-step explanation:
The equation of a line can be written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
This is also known as the slope-intercept form.
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }, \\ where \: (x1, y1) \: is \: the \: 1st \: coordinate \: and \: (x2, y2) \: is \: the \: 2nd \: coordinate.[/tex]
Find the value of m using the gradient formula above:
[tex]m = \frac{4 - 0}{0 - 8} \\ m = \frac{4}{ - 8} \\ m = - \frac{1}{2} [/tex]
Substitute m= -½ into the equation:
y= -½x +c
To find the value of c, substitute a pair of coordinates:
When x= 0, y=4,
[tex]4 = - \frac{1}{2} (0) + c \\ 4 = c \\ c = 4[/tex]
Thus, the equation of the line is y= -½x +4.

Answer:
$10p + $ 2.99 = $32.99
Step-by-step explanation:
I got this because he got multiple pizzas that are each $10, but we don't know how many there are, so I put $10p together.
He also pays $2.99 as a delivery charge.
And I ended it with the equation equaling $32.99 because that is the total he paid.

He solved for x and got x = plus-or-minus StartRoot StartFraction uppercase A Over 18 EndFraction minus 1 EndRoot Which of the following is an equivalent equation for x?
Answer: x= a-18/18
Step-by-step explanation:
The expression equivalent to this is letter A. x= ±√(A-18/18)
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
To solve for x in the equation for the area which was given to be;
A = 18(x^2 + 1),
So, we divide both sides of the equation by 18 first.
A/18 = x^2 + 1
Then, we subtract 1 from both sides of the equation;
A/18 – 1 = x^2
Then, we simplify the expression in the left side of the equation;
(A – 18)/18 = x^2
And obtain the square root from both sides of equation,
x= ±√(A-18/18)
Therefore, The expression equivalent to this is letter A. x= ±√(A-18/18)
