Step-by-step explanation:
A software company has found that on Mondays, the polynomial function C(t) = −0.0625t4 + t3 − 6t2 + 16t approximates the number of callers to its hotline at any one time. Here, t represents the time, in hours, since the hotline opened at 8:00 A.M. How many service technicians should be on duty on Mondays at noon if the company doesn't want any callers to the hotline waiting to be helped by a technician?
Answer:
At least 16 service technicians
Step-by-step explanation:
Given
[tex]C(t) = -0.0625t^4 + t^3 - 6t^2 + 16t[/tex]
Required
Number of service technician to be online at 12 noon
First, we calculate the value of t
[tex]t = 12\ Noon - 8:00AM[/tex]
[tex]t = 4[/tex]
Substitute [tex]t = 4[/tex] in [tex]C(t) = -0.0625t^4 + t^3 - 6t^2 + 16t[/tex]
[tex]C(4) = -0.0625 * 4^4 + 4^3 - 6 * 4^2 + 16 * 4[/tex]
[tex]C(4) = 16[/tex]
This implies that there are 16 customers online at 12 noon.
If 16 customers are online, then there should be at least 16 service technicians online.

Answer:
f = 2 1/4c
Step-by-step explanation:
Number of cups of flour is proportional to the number of cakes
Number of cups of flour = f
Number of cakes = c
Therefore,
f = k * c
Where,
k = constant of proportionality
Number of cups of flour = 22 1/2 cups
Number of cakes = 10 cakes
f = k * c
22 1/2 = k * 10
45/2 = 10k
k = 45/2 ÷ 10
= 45/2 × 1/10
= (45*1) / (2*10)
= 45/20
= 2 5/20
k = 2 1/4
The equation is
f = k * c
f = 2 1/4 * c
f = 2 1/4c

less than what number?
Answer:
C. 74
Step-by-step explanation:
add up all the numbers but not the value so you have 18 numbers. divide that by 2 and get 9. so 74 is between 73 and 78 so it divides the 18 numbers evenly into 9 and 9.
Find the value of x so that the ratios 8: x and 12: 18 are equivalent.
Answer:
I could be wrong, but I think it's x=12
Answer:
Step-by-step explanation:
First let's set this into a proportion:
[tex]\frac{8}{x}=\frac{12}{18}\\144=12x\\12=x[/tex]
Hope this helps
Can someone helpppp plssss
Answer:
angleQ+angleR is 180degrees because of the properties of isoceles trapezoid. So, if you set equation and solve, you'll get the fact that x is 12, and angleR is 130degrees, and angleQ is 50degrees. According to the properties of isoceles trapezoid, angleQ is the same as angleT. So, angleT is 50degrees

Answer:
If using one pound of pumpkin the baker needs to use 4 pounds of flour mixture
Step-by-step explanation:
step 1: I am going to convert the measurements
into decimals
8/5=1.6
2/5=.4
step 2: I will use cross multiplication to find out how much pumpkin for one pound of flour
1.6=.4
1=?
1*.4=.4/1.6=.25
step 3: I will convert .25 into a fraction
.25=1/4
for every 1/4 pound pumpkin, I will use 1 pound of flour
which is why
If using one pound of pumpkin the baker needs to use 4 pounds of flour mixture

There is a bag filled with 4 blue, 3 red and 5 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 green?
Answer:
Step-by-step explanation:
P(g=1) is equal to
1-P(g=0)-P(g=2)
P(g=0)=(7/12)(6/11)
P(g=2)=(5/12)(4/11) so
P(g=1)=1-(42/132)-(20/132)
P(g=1)=(132-42-20)/132
P(g=1)=70/132
P(g=1)=35/66
(50pts) The distance covered and the time taken by a car are plotted in a graph.
a. Find the slope of the line in the graph.
b. Calculate the distance traveled by the car at the 20th second.
c. Calculate the speed of the car.
Answer:
a=2
b=40m
c=2m/s
Step-by-step explanation:
slope is rise over run so 10/5 simplified is 2/1 or 2
for b just look at the graph at the 20th second
for c you do distance over time so basically the same thing as a 10/5 which is 2m/s

Find the area of a rectangle with side lengths 5 /8 ft. And 1/ 3 ft. A 1-foot by 1-foot square is shown. The square is divided into 8 rows and 3 columns. Therefore, there are a total of 24 equal-sized cells inside the square. A. 5 /11 ft 2 B. 1 11/ 12 ft 2 C. 6/ 11 ft 2 D. 5 /24 ft 2
Answer: 5/24 ft²
Step-by-step explanation:
To find the the area of a rectangle with side lengths 5/8 ft and 1/3 ft, we need to know that the area of a rectangle is gotten by multiplying the length by the width.
In this case, the area of the rectangle will be:
= 5/8 × 1/3
= 5/24 ft²
the graph of y=x^2-4x is shown. name a zero of the function below
Answer:
0 and 4
Step-by-step explanation:
y = x^2 - 4x can be factored as follows: y = x(x - 4).
We find the zeros by setting this factored form equal to zero and solving for x:
x(x - 4) = 0, or x = 0, or x = 4.
The two zeros of this function are 0 and 4.
An expression is written in the box.
x²+x-4
What is the value of this expression when x = -6?
0 -46
0 -35
O 26
38
Answer:
the solution to that is 26.
Answer:
26
Step-by-step explanation:
Substitute x = - 6 into the expression
x² + x - 4
= (- 6)² + (- 6) - 4
= 36 - 6 - 4
= 30 - 4
= 26
