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.
(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

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

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
Half the number of guesses are
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.
HELP I WILL MARK YOU GOOD!!
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

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

a rectangle is 16 feet long and 8 feet wide find its area
The area of the rectangle is 128 square feet.
To find the area of a rectangle, you multiply the length by the width. In this case, the rectangle is 16 feet long and 8 feet wide.
Area = Length * Width
Substituting the given values:
Area = 16 feet * 8 feet
To perform the calculation, multiply the numbers:
Area = 128 square feet
Therefore, the area of the rectangle is 128 square feet.
The area of a rectangle represents the total amount of space enclosed within its boundaries. In this case, the rectangle measures 16 feet in length and 8 feet in width, so the area is calculated as 16 feet multiplied by 8 feet, resulting in 128 square feet.
The concept of area is fundamental in geometry and is used to measure the size of two-dimensional shapes. In the case of a rectangle, the area represents the product of its length and width, as every point within the rectangle contributes to its overall size.
Knowing the area of a rectangle can be useful in various situations. For example, if you want to determine how much flooring material is required to cover a rectangular room, you would need to know the area of the floor.

Step-by-step explanation:
180-43=137
Answer:
180 - (43 + 56) = 81 (angle 1)
180 - 81 = 99 (angle 2)
180 - 56 = 124 (angle 3)
180 - 43 = 137 (angle 4)
Step-by-step explanation:

For the top part, both equations are vertical angles, so both equations will equal the same angle.
(4 + 23x) = (24x)
4 + 23x = 24x
4 = 24x - 23x
4 = x
Plug in x = 4 into both equations.
4 + 23(4) = 24(4)
4 + 92 = 96
96 = 96
Since x = 4 is a solution for both equations, the angle that is equal to both is 96 degrees.
Answer: 96 degrees is the angle--------------------------------------------------------------------------------------------------------------
For the bottom part, both equations lie on the same straight line, so adding both equations together will equal 180 degrees.
(x + 120) + (x + 80) = 180
x + 120 + x + 80 = 180
2x + 200 = 180
2x = 180 - 200
2x = -20 (don't worry about having a negative solution)
x = -10
Plug in x = -10 into both equations.
(-10) + 120 + (-10) + 80 = 180
110 + 70 = 180
180 = 180
Since x = -10 is a solution for both equations, the angle for equation (x + 120) is 110 degrees and angle for equation (x + 80) is 70 degrees.
Answer: Since the question asked to find a measure of the angle indicated in bold, the angle measure is 70 degrees.Kishany is investing in a savings account that earns 3.85% interest compounded annually. How much will Kishany have in the account at the end of the 3rd year if she deposits $600 in the account?
a
$2,310
b
$672.00
c
$558.38
d
$669.30
Answer:
The amount in the account after 3 years is $672.00
Step-by-step explanation:
Here, we want to use the compound interest formula
A = P(1 + r/n)^nt
A is the amount in the account after the given time
P is the principal which is the deposit amount = $600
r is the interest rate = 3.85% = 3.85/100 = 0.0385
n is the number of times interest is compounded yearly (since it is annually, n = 1)
t is the time in years = 3
Substituting these values;
A = 600(1 + 0.0385/1)^(3 * 1)
A = 600(1.0385)^3
A = $672
