evaluate 9P4
A. 9
B. 362,880
C. 126
D. 3024
Answer:
3024
Step-by-step explanation:
3024
Option (D) 3024 is the permutation value is the correct answer.
What is a permutation?A permutation is an arrangement of objects in a definite order. It is a number of ways a particular set can be arranged, where the order of the arrangement matters.
For the given situation,
The value of 9P4
The formula to find permutation is
[tex]nP_{r}=\frac{n!}{(n-r)!}[/tex]
Here, n = 9 and r = 4
⇒ [tex]9P_{4}=\frac{9!}{(9-4)!}[/tex]
⇒ [tex]\frac{9!}{5!}[/tex]
⇒ [tex]\frac{5!(6)(7)(8)(9)}{5!}[/tex]
⇒ [tex](6)(7)(8)(9)[/tex]
⇒ [tex]3024[/tex]
Hence we can conclude that option (D) 3024 is the permutation value is the correct answer.

The parallelogram shown below has an area of 35 units^2 2 squared. Find the missing height. h =h=h, equals units
Answer:
h = 5 units
Step-by-step explanation:
Given that,
The area of the parallelogram, A = 35 unit²
In the attached figure, we can see that the base is 7 unit.
We know that,
Area of a parallelogram, A = b × h
So,
[tex]h=\dfrac{A}{b}\\\\h=\dfrac{35}{7}\\\\h=5\ units[/tex]
So, the value of h is equal to 5 units.
find the slope of the line that passes through the given points (9, -3) and (9, 4)
Answer: No slope.
Step-by-step explanation:
No slope, the x values are the same yet they have different Y values so there isn't a slope and this isn't a function.
Find the amount accumulated after investing a principal P for t years at an interest rate compounded k times per year. P = $3,500 r= 5% t = 10 k = 4
A = ?
Answer:
To the nearest cent, the accumulated amount over the 10 years is $5,752.67
Step-by-step explanation:
Here, we want to use the given formula to find the accumulated amount on the deposit/investment
we have this as follows;
A = P(1 + r/k)^kt
P is the amount invested which is the principal = $3,500
r is the interest rate = 5% = 5/100 = 0.05
k is the number of times interest is compounded yearly = 4
t is the number of years = 10
Substituting these values in the formula, we have;
A = 3500(1 + 0.05/4)^(4 * 10)
A = 3500 (1 + 0.0125)^40
A = 3500(1.0125)^40
A = $5,752.67
The Area of a rectangular garden can be represented by the expression 15x 2 - 7x - 2. The length of the garden can be represented by 5x + 1. Write an expression that represents the perimeter of the garden.
Answer:
16x-2
Step-by-step explanation
Area of the garden = length × width
Substitute the given value
15x 2 - 7x - 2. = 5x+1 × width
Factorize the area
15x^2 - 7x - 2.
15x²-10x+3x -2 =0
5x(3x-2)+1(3x-2)
5x+1(3x-2)
Hence other side so be 3x-2
Perimeter = 2(L+W)
P = 2(5x+1+3x-2)
P = 2(8x-1)
P = 16x-2
Hence the expression that represents the Perimeter is 16x-2

If you bought a stock last year for a price of $103, and it has risen 7% since then, how
much is the stock worth now, to the nearest cent?
Answer:
the stock is worth $110.21
Step-by-step explanation:
The first thing you want to do is multiply 0.07 and 103, to find out what 7% of 103 is. When you multiply those two numbers you are going to get 7.21. You are then going to add 103 and 7.21 to find out how much it would be worth now.
Answer:
$110.21
Step-by-step explanation:
well 7% of 103 is 7.21 so if you add that to 103 it = 110.21

Answer:
[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]
Step-by-step explanation:
Since the hyperbola opens left and right with a center at the origin, then
[tex]\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1[/tex]
In the graph a = 60 and b = 11
So
[tex]\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1[/tex].

Mr Malloy wants to make sure amo and max get the best possible grade after five tests and can either give a grade based on the median or the mean
Answer:
• Median for Amo
• Mean for Max
Step-by-step explanation:
Amo's mean score:
= (97 + 92 + 89 + 55 + 90)/ 5
= 84.60
= 85
Max's mean score:
= (68 + 97 + 65 + 92 + 65) / 5
= 77
Amo's median:
First arrange the numbers in ascending order:
55, 89, 90, 92, 97
Median is middle which is 90.
Max's median:
65, 65, 68, 92, 97
Median is 68
Mr Javier should use Median for Amo and Mean for Max.
A number cube is rolled twice. What is the P (2 and then odd number)?
Answer:
P (2 and then odd number) = [tex]\frac{1}{12}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
A number cube is rolled twice.
Possible outcomes are as follows:
[tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]
[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]
[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]
[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]
[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]
[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]
Total number of outcomes = 36
Favorable outcomes include outcomes with 2 and then odd number.
So,
Favorable outcomes are [tex](2,1),(2,3),(2,5)[/tex]
Number of favorable outcomes = 3
Probability is equal to number of favorable outcomes divided by total number of outcomes.
Therefore,
P (2 and then odd number) = Number of favorable outcomes ÷ Total number of outcomes
[tex]=\frac{3}{36}[/tex]

find the area of each sector shown (the shaded section)
Answer:
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].
Step-by-step explanation:
Area of a sector = (θ ÷ 360) [tex]\pi[/tex][tex]r^{2}[/tex]
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{26}{2}[/tex] = 13 m
θ = 360 - (180 + 160)
= 360 - 340
= [tex]20^{o}[/tex]
Thus,
area of the given sector = [tex]\frac{20}{360}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]
= [tex]\frac{20}{360}[/tex] x x [tex]\frac{22}{7}[/tex] x 169
= 29.5079
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].

Can someone please help me and write out the answer
Answer:
y = 2x+1
Step-by-step explanation:
From the question,
Using the equation of a straight line
y = mx+c................. Equation 1
Where m = slope of the line, c = intercept on the y axis.
From the graph, The two point co-ordinate shown os
Point 1 = (-2,0)
Point 2 =(6,4)
s = (y₂-y₁)/(x₂-x₁).............. Equation 2
Where y₂ = 6, y₁ = -2, x₂ = 4, x₁ = 0
Substitute into equation 2
s = (6-(-2))/(4-0)
s = (6+2)/4
s = 8/4
s = 2.
Also from the graph,
c = 1
Substitute these values into equation 1
y = 2x+1
Hence the equation of the line is y = 2x+1

The temperature drops to a rate of five degrees per hour. Be d the number of degrees that lowers the temperature. Be the number of hours you spend. What is the dependent variable?
Answer:
d, the number of degrees that the temperature was lowered by
Step-by-step explanation:
The dependent variable in this scenario would be d, the number of degrees that the temperature was lowered by. This is because the value of this variable depends on the actual amount of hours that have passed by. Therefore, depending on the number of hours, the value of d could be completely different. The variable h for the number of hours does not depend on any other variable in the equation and has its own value, but since d depends on h then it would be the dependent variable in this scenario.
Solve the inequality for x
8^x>24
Answer:
Step-by-step explanation:
Remark
I hope you have some idea how to make your calculator use logs. This problem is impossible without being able to take the log of each side.
Solution
log(8)^x > log 24 Logs lets you bring down x and multiply it by log24
x log 8 > log 24 Be careful what you do next. Don't use log 3
x > log(24)/log(8)
x > 1.3802/0.9031
x>1.5284
As wrong as this may look, it is correct.
Check it
8^1.5284 = 24.00395
The difference is that 1.5284 has been rounded just a slight bit.
