13d +8= -1
d=?
Answers
Answer:
d = (-9/13)
Step-by-step explanation:
13d + 8 = -1
-8 -8
13d = -9
÷13 ÷13
d = ( -9/ 13 )
I hope this helps!
Answer:
d = -9/13
Step-by-step explanation:
13d +8= -1
Subtract 8 from both side
13d +8-8= -1-8
13d = -9
Divide 13 from both side
13d/13 = -9/13
d = -9/13
The number of tickets sold each day for an upcoming performance is given by p(x) = -0.4x2 + 8.8x + 13, where x is the number of days since the concert was first announced. When will daily ticket sales peak and how many tickets will be sold that day?
Answers
Answer:
The maximum sale of the tickets is 158 on the [tex]11^{th}[/tex] day.
Step-by-step explanation:
The number of tickets sold each day, p(x), for an upcoming performance is
[tex]p(x)=-0.4x^2+8.8x+13[/tex]
where x is the number of days since the concert was first announced.
For peak sales, the point of maxima has to be determined.
So, differentiate the function of the number of tickets sold each day, p(x), with respect to the number of days, x, and equate it to zero to get the extremum point (maxima or minima), i.e.
[tex]\frac {p(x)}{dx}=0[/tex]
[tex]\Rightarrow -0.8x+8.8=0[/tex]
[tex]\Rightarrow x=\frac{8.8}{0.8}=11[/tex]
Now, check the sign of the second derivative at x=11, to ensure the obtained point is corresponding to the maxima or minima,
[tex]\frac {p^2(x)}{dx^2}=-0.8[/tex]
As the second derivative is negative, so x=11 is the point corresponding to maxima.
Hence, on the [tex]11^{th}[/tex] day the daily ticket sales will be at the peak.
Putting x=11 in the function p(x) to get the number of tickets sold that day.
[tex]p(x=11)= -0.4(11)^2+8.8(11)+13[/tex]
[tex]\Rightarrow 158.2.[/tex]
The number of tickets should be an integer, the obtained peak value is 158.2 so the higher integral value is not possible but the lower integral value is possible.
So, the maximum sale of the tickets is 158 on the [tex]11^{th}[/tex] day.

You have a bull's eye where each section is 2" wide as shown in the diagram. Find the following probabilities.
Answers
Answer:
a) 1/16
b) 7/16
Step-by-step explanation:
a) The area of the outside circle is π (8")² = 64π in².
The area of the center circle is π (2")² = 4π in².
So the probability is (4π / 64π) = 1/16.
b) The area of the outside strip is π [(8")² − (6")²] = 28π in².
So the probability is (28π / 64π) = 7/16.

At the airport, ten people are waiting on standby. two seats become available, one first-class and one coach, There are 90 ways to fill the two seats.
It is given that there are ten people waiting on standby.
Two seats are available, One is first class and another one is coach.
It is required to find how many ways are there to fill the two seats.
What is permutation?A permutation can be defined as the number of ways a set can be arranged.
We have ten people and two seats in which only two people can seat out of ten.
It is a problem based on the permutation concept.
So for the first seat, there are 10 ways to fill the first seat
and for the second seat, there are [tex](10-1)[/tex] ways to fill the second seat.
If "P" is the number of ways we can assign the seats:
Then, P = 10×(10-1) = 10×9 = 90
Thus, there are 90 ways to fill the two seats.

What is the slope of the line that passes through the points (3,9) and (7,5)? Write
your answer in simplest form.
Answers
Answer:
M = -1
Step-by-step explanation:
Use the slope formula:
M = (y2-y1)/(x2-x1)
M = (5-9)/(7-3)
M = -1
The required slope for the lines -1.
Given that,
To determine the slope of the line that passes through points (3,9) and (7,5).
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx, where x is in degrees.
What is simplification?The process in computation to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Slopes of the line can be given as,
m = [y₂ - y₁ ] / [x₂ - x₁]
for points, (3,9) and (7,5)
m = 5 - 9 / 7 - 3
m = -4 / 4
m = 1
Thus, the required slope for the lines is -1.

An angle between 0 and 2π that is coterminal with 960° is
Answers
Answer:
4 pi/3
Step-by-step explanation:
960 degrees in standard position is the same thing as 960-360 = 600 degrees in standard position because rotating the second line 360 degrees just brings it back to where it started.
Do it again to get 600 - 360 = 240
240 degrees would end up in the same spot as 600 degrees and 960 degrees, so they are all coterminal.
Convert 240 degrees to radians:
240 * pi/180 = 4pi/3.

Answers
Answer:
c
Step-by-step explanation:
The equation =( denominater * derivative of numerator - numerator * derivative of denominator) / denominator ^2
so the qstn is (x^2 + 3x +2) / (x+3)
apply the values as the above eqtn states
ie,[ (x+3) * derivative of (x^2 +3x + 2)] - [( x^2 +3x + 2) *derivative of (x+3)] /
(x+3)^2
derivative of numerator, (x^2 +3x + 2) is 2x+3
" of denominator, (x+3) is 1
so we get
[(x+3)* (2x + 3 ) - (x^2 +3x + 2) *1 ] / (x+3)^2
open the brackets
[ 2x^2 + 3x + 6x + 9 - x^2 +3x + 2 ] / (x+3)^2
