Answer:
P = n * t * (S - C) - H - (n * W)
n = (P + H) / (tS - tC - W)
Step-by-step explanation:
n = number of employees to be hired
P = profit
W = employee wages per day
t = average toys made by each employee per day
S = selling price of each product
C = cost price of each product
H = daily overhead costs
Equation for profit is selling price - cost price for all the toys made for that day
which is no. of employees * t * (S - C)
we will also cut daily overhead costs from profit
and also daily wages for all employees
P = n * t * (S - C) - H - (n * W)
Now we have to find n based on other factors / variables
P = ntS - ntC - H - nW
P = n (tS - tC - W) - H
P + H = n (tS - tC - W)
n = (P + H) / (tS - tC - W)

Nico has $11.50 deducted from his weekly paycheck for health care. If his employer pays 90% of the premium, how much is his annual premium ?
A) $5980
B) $2990
C) $665
D) $115
Answer:
Nico's annual premium is A) $5980.
Nico has $11.50 deducted from his weekly paycheck for health care.
So,
Nico's annual deduction are:
Since there are 52 weeks in a year.
So,
11.50*52=$598
His employer pays 90% of the premium, means Nico pays 10%.
And $598 is 10% of total annual premium.
Let annual premium is x.
10%of x =$598
10/100*x=$598
x=$598*10
x=$5980
Hence, Nico's annual premium is $5980

(c). It is well known that the rate of flow can be found by measuring the volume of blood that flows past a point in a given time period. The volume V of blood flow through the blood vessel is V = =[₁2πvr dr where v= K (R² − r²) is the velocity of the blood through a vessel. In the velocity of the blood through a vessel, K is a constant, the maximum velocity of the blood, R is a constant, the radius of the blood vessel and r is the distance of the particular corpuscle from the center of the blood vessel.
(i) If R = 0.30 cm and v= (0.30-3.33r²) cm/s, find the volume.
(ii) Construct and develop a general formula for the volume of the blood flow. [Verify your answer by MATHEMATICA and attach the printout of the commands and output
(i) Given that
[tex]V(R) = \displaystyle \int_0^R 2\pi K(R^2r-r^3) \, dr[/tex]
when R = 0.30 cm and v = (0.30 - 3.33r²) cm/s (which additionally tells us to take K = 1), then
[tex]V(0.30) = \displaystyle \int_0^{0.30} 2\pi \left(0.30-3.33r^2\right)r \, dr \approx \boxed{0.0425}[/tex]
and this is a volume so it must be reported with units of cm³.
In Mathematica, you can first define the velocity function with
v[r_] := 0.30 - 3.33r^2
and additionally define the volume function with
V[R_] := Integrate[2 Pi v[r] r, {r, 0, R}]
Then get the desired volume by running V[0.30].
(ii) In full, the volume function is
[tex]\displaystyle \int_0^R 2\pi K(R^2-r^2)r \, dr[/tex]
Compute the integral:
[tex]V(R) = \displaystyle \int_0^R 2\pi K(R^2-r^2)r \, dr[/tex]
[tex]V(R) = \displaystyle 2\pi K \int_0^R (R^2r-r^3) \, dr[/tex]
[tex]V(R) = \displaystyle 2\pi K \left(\frac12 R^2r^2 - \frac14 r^4\right)\bigg_0^R[/tex]
[tex]V(R) = \displaystyle 2\pi K \left(\frac{R^4}2- \frac{R^4}4\right) [/tex]
[tex]V(R) = \displaystyle \boxed{\frac{\pi KR^4}2} [/tex]
In M, redefine the velocity function as
v[r_] := k*(R^2 - r^2)
(you can't use capital K because it's reserved for a built-in function)
Then run
Integrate[2 Pi v[r] r, {r, 0, R}]
This may take a little longer to compute than expected because M tries to generate a result to cover all cases (it doesn't automatically know that R is a real number, for instance). You can make it run faster by including the Assumptions option, as with
Integrate[2 Pi v[r] r, {r, 0, R}, Assumptions -> R > 0]
which ensures that R is positive, and moreover a real number.
Trey runs 3 miles in 25 minutes. At the same rate, how many miles would he run in 20 minutes?
Answer:
Step-by-step explanation:
Set up a proportion.
3/25 = x / 20 Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.
Cross multiply
3 * 20 = 25 * x Combine
60 = 25x Divide by 25
60/25 = x
x = 2.4 miles in 20 minutes.
Answer:
In 20 minutes, Trey would run 2.4 miles.
Step-by-step explanation:
20x = 25
x = 4/5
This means we multiply the number by 0.8
3 * 0.8 =
3/25 = 2.4/20
2.4 miles / 20 minutes

The probability that it will rain tomorrow is dependent on whether or not it is raining today and whether or not it rained yesterday. If it rained yesterday and today, there is a 20% chance it will rain tomorrow. If it rained one of the days, there is a 60% chance it will rain tomorrow. If it rained neither today nor yesterday, there is a 20% chance it will rain tomorrow. Given that it is raining today and that it rained yesterday, write a function rain_days to calculate the probability that it will rain on the nth day after today.

) 9 mini flashlights cost $7.02. If the flashlights all cost the same amount, how much does
each flashlight cost?
Answer:
$1.28 each
Step-by-step explanation:
9 / $7.02 = $1.28
Answer:
each flashlight costs 0.78$
Step-by-step explanation:
Since we know that 9 flashlights costs 7.02$ then all we need to do is divide 7.02 by 9 and we get .78 so the cost of one flashlight is 0.78 cents

Which statements are true about the polynomial function?
f(x)=x4+5x3−x2−5x
Answer:
f(x) divided by (x+5) has a remainder of 0 & f(x) = x^4+5x^3 -x^2-5x
Step-by-step explanation:
I just took the test
The correct statements are -
f(x) = 0 at x = -5 f(x) when divided by (x + 5) gives the remainder zero.What is the general equation of a quadratic equation?The general equation of a quadratic equation is -
[y] = ax² + bx + c
where -
[a], [b] and [c] are constants.
We have the function [tex]x^{4}+5x^{3}-x^{2}-5x\\[/tex].
Refer to the image of the graph of the given polynomial function. We can see that at x = -5, f(x) = 0. Now, x = -5 is the solution of the polynomial f(x), so (x + 5) is a factor of f(x). Hence, f(x) when divided by (x + 5) gives the remainder zero.
Therefore, the correct statements are -
f(x) = 0 at x = -5 f(x) when divided by (x + 5) gives the remainder zero.To solve more questions on GRAPHS, visit the link below-

solve 0+x^2-10x+30 by completing the square
Answer:
See answer below
Step-by-step explanation:
x² - 10x + 30 = 0
x² - 10x = -30
x² - 10x + 25 = -30 +25 1/2 of the x term and square that number and add to
both side.
x² -10x + 25 = -5
(x - 5)(x - 5) = -5
[tex]\sqrt{(x-5)(x-5)^2}[/tex] = [tex]\sqrt{-5}[/tex]
If you are in Algebra II , then the answer is not a real answer it will be
(x - 5)² = ±5i
