Evaluate the expression 9P1
Answer :
9
Explanation :
The expression above signifies the Permutation expression
Permutation expression is given as nPr
The Permutation expression is calculated as:
nPr = P(n, r) = n! / (n - r)!
It the above question, we were asked to evaluate the expression 9P1
From the above question, we can see that:
n = 9 and r = 1
Therefore, the expression
9P1 = 9! / ( 9 - 1) !
9P1 = 9! / 8!
= 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 / 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 362880 /40320
= 9
Therefore, the evaluation of the expression 9P1 = 9
Final answer:
To evaluate the expression 9P1, we calculate the permutation for selecting 1 item from 9, which simplifies to 9/1, giving us the answer of 9.
Explanation:
The student has asked to evaluate the expression 9P1, which is a permutation problem. To find 9P1, we use the permutation formula, which is P(n, k) = n! / (n-k)!, where n is the total number of items to choose from, and k is the number of items to choose. In this case, since we want to choose 1 item from 9, the permutation is calculated as:
Identify the values of n and k (n=9, k=1).Apply the permutation formula: 9P1 = 9! / (9-1)! = 9! / 8!.Simplify the factorial expression: 9! / 8! = 9 / 1 = 9.Therefore, the value of 9P1 is 9.

A rectangle has a length of 7.5 inches and a width of 3 inches. This rectangle is dilated by a scale factor of 2.2 to create a new rectangle. What are the dimension of the new rectangle? Length and Width
Answer:
For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:
[tex] L_f = 2.2 L_i= 2.2* 7.5 in = 16.5 in[/tex]
[tex] W_f = 2.2 w_i = 2.2 * 3 in = 6.6 in[/tex]
Step-by-step explanation:
The area of a rectangle is given by [tex] A = L *W[/tex]
For this case is the rectangle is dilated a factor of 2.2 we assume that the expansion is in all the dimensions so then the new length and width are:
[tex] L_f = 2.2 L_i= 2.2* 7.5 in = 16.5 in[/tex]
[tex] W_f = 2.2 w_i = 2.2 * 3 in = 6.6 in[/tex]
And the area would be (2.2)^2 times the initial area since is defined as [tex]A = L_f W_f [/tex]
Answer:
The length and the width of the new rectangle are 16.5 inches and 6.6 inches respectively
Step-by-step explanation:
Given
Shape: Rectangle
[tex]Length = 7.5 inches[/tex]
[tex]Width = 3 inches[/tex]
[tex]Scale factor = 2.2[/tex]
Required
Dimension of the new rectangle
The dimensions of the new rectangle can be solved by multiplying the scale factor by the old dimensions;
This means that
New Length = Scale factor * Old Length
and
New Width = Scale factor * Old Width
Calculating the new length
New Length = Scale factor * Old Length
Substitute 2.2 for scale factor and 7.5 for old length; This gives
[tex]New Length = 2.2 * 7.5 inches[/tex]
[tex]New Length = 16.5 inches[/tex]
Calculating the new width
New Width = Scale factor * Old Width
Substitute 2.2 for scale factor and 3 for old width; This gives
[tex]New Width = 2.2 * 3 inches[/tex]
[tex]New Width= 6.6 inches[/tex]
Hence, the length and the width of the new rectangle are 16.5 inches and 6.6 inches respectively

The equation that models the path of a rocket into the air is given by :
[tex]h(t)= -16t^2+864t[/tex]
It is required to find the time after which the rocket will hit the ground. When it hits the ground, the height of the rocket will becomes zero. It means,
h(t) = 0
i.e.
[tex]-16t^2+864t=0\\\\16t(-t+54)=0\\\\16t=0, -t+54=0\\\\t=0\ and\ t=54\ s[/tex]
It means after 54 seconds, the rocket will hit the ground.
A bicycle factory produces 1505 bicycles in a week. How many bicycles will it produce in 30 days?
and
20 apples are distributed between Aaron and Ben in the ratio 2 : 3. Find, how many does each get?
Answer:
It will produce 6450 bicycles in 30 days
Aaron has 8 apples and Ben has 12 apples
Step-by-step explanation:
A)
A bicycle factory produces 1505 bicycles in a week.
No. of days in 1 week = 7
So, Number of bicycles produced in 7 days = 1505
Number of bicycles produced in 1 day =[tex]\frac{1505}{7}[/tex]
Number of bicycles produced in 30 days = [tex]\frac{1505}{7} \times 30=6450[/tex]
So, It will produce 6450 bicycles in 30 days
B)20 apples are distributed between Aaron and Ben in the ratio 2 : 3.
Let the ratio be x
So, Aaron has apples = 2x
Ben has apples = 3x
So, 2x+3x=20
5x=20
x=4
Aaron has apples = 2x =2(4)=8
Ben has apples = 3x =3(4)=12
Hence Aaron has 8 apples and Ben has 12 apples
In △CDE , CD=10 , DE=7 , and m∠E=62∘ . What is m∠D to the nearest tenth of a degree?
We have been given that in △CDE , CD=10 , DE=7 , and m∠E=62 degrees. We are asked to find the measure of angle D.
We will use law of sines to solve our given problem.
[tex]\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}[/tex], where, a, b and c are opposite sides to angles A, B and C respectively.
First of all we will find measure of angle C as:
[tex]\frac{7}{\sin(C)}=\frac{10}{\sin(62^{\circ})}[/tex]
[tex]\sin(C)=\frac{7\cdot \sin(62^{\circ})}{10}[/tex]
[tex]\sin(C)=\frac{7\cdot 0.882947592859}{10}[/tex]
[tex]\sin(C)=0.6180633150013[/tex]
Now we will use arcsin to solve for C as:
[tex]C=\sin^{-1}(0.6180633150013)[/tex]
[tex]C=38.174844995363^{\circ}[/tex]
[tex]C\approx 38.2^{\circ}[/tex]
Now we will use angle sum property to find measure of angle D.
[tex]\angle D+\angle C+\angle E=180^{\circ}[/tex]
[tex]\angle D+38.2^{\circ}+62^{\circ}=180^{\circ}[/tex]
[tex]\angle D+100.2^{\circ}=180^{\circ}[/tex]
[tex]\angle D+100.2^{\circ}-100.2^{\circ}=180^{\circ}-100.2^{\circ}[/tex]
[tex]\angle D=79.8^{\circ}[/tex]
Therefore, the measure of angle D is approximately [tex]79.8^{\circ}[/tex].
Measure of angle D will be 79.8°.
Sine rule in a triangle, Sine rule,[tex]\frac{c}{\text{sinC}}= \frac{d}{\text{sinD}}= \frac{e}{\text{sinE}}[/tex]
Here, c, d and e are the sides and C, D, E are the angles opposite
to these sides of the given triangle.
Given in the question,
In ΔCDE,
CD = 10 units
DE = 7 units
m∠E = 62°
By applying sine rule,
[tex]\frac{7}{\text{sinC}}= \frac{d}{\text{sinD}}= \frac{10}{\text{sin(62)}}[/tex]
[tex]\frac{7}{\text{sinC}}= \frac{10}{\text{sin(62)}}[/tex]
[tex]\text{sin(C)}=\frac{\text{sin(62)}\times 7}{10}[/tex]
[tex]=0.618063[/tex]
C = [tex]\text{sin}^{-1}(0.618063)[/tex]
C = 38.175°
≈ 38.2°
By triangle sum theorem of a triangle,
m∠C + m∠D + m∠E = 180°
38.2 + m∠D + 62° = 180°
m∠D = 79.8°
Therefore, measure of angle D will be 79.8°.

The Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine that the hotel will average $125 a night and tickets for scuba diving are $75. The inequality can be used to determine the number of nights the Jones family could spend at the hotel
750≥75 + 125h
Answer:
Value of h greater than 5.4 will make inequality false.
Step-by-step explanation:
This question is incomplete; here is the complete question.
The Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine that the hotel will average $125 a night and tickets for scuba diving are $75. The inequality can be used to determine the number of nights the Jones family could spend at the hotel 750 ≥ 75 + 125h. What value of h does NOT make the inequality true?
From the given question,
Per night expense (expected) = $125
If Jones family stays in the hotel for 'h' days then total expenditure on stay = $125h
Charges for scuba diving = $75
Total charges for stay and scuba diving = $(125h + 75)
Since Jones family has saved $750 for the vacation trip so inequality representing the expenses will be,
125h + 75 ≤ 750
125h ≤ 675
h ≤ [tex]\frac{675}{125}[/tex]
h ≤ 5.4
That means number of days for stay should be less than equal to 5.4
and any value of h greater than 5.4 will make the inequality false.

Here are the low temperatures (in degrees Fahrenheit) for one week in Montreal, Canada:
-3.5ºF, 5ºF, 1.5ºF, -0.5ºF, -2ºF, 2.5ºF, -4ºF
Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute value of each.
You have to choose two days at random and compare the values of temperature registered those days and compare them, for example:
Day 1: 3rd day: 1.5ºF
Day 2: 7nth day: -4ºF
Comparison of Day 1 and Day 2:
Remember:
"<" indicates that the value from the left is less than the value from the right.
">" indicates that the value from the left is greater than the value from the right.
The temperature registered on Day 1 is 1.5ºF and the temperature registered on Day 2 is -4ºF, as you notice the second temperature is negative and therefore is less than the first temperature:
1.5ºF > -4ºF
Comparison of days with absolute value:
To compare absolute values you have to disregard the sign and consider only the number of the temperature:
|Day 1|= |1.5ºF|
|Day 2|= |4ºF|
Then the registered temperature of Day 1 is less than the registered temperature on Day 2:
|1.5ºF| < |4ºF|
I hope this helps!
Answer:
-4ºF and 1.5ºF

Answer:28 green and 35 red
Step-by-step explanation:
Given
If there are r red counter and g green counter then
Probability of drawing a green counter is [tex]P(g)=\frac{4}{9}[/tex]
and [tex]P(g)=\frac{\text{No of g counter}}{\text{Total no of counter}}[/tex]
Thus [tex]\frac{\text{No of g counter}}{\text{Total no of counter}}=\frac{4}{9}[/tex]
[tex]\frac{g}{g+r}=\frac{4}{9}[/tex]
[tex]\Rightarrow 9g=4g+4r[/tex]
[tex]\Rightarrow 5g=4r\quad \ldots(i)[/tex]
Also if 4 red and 2 green counter is added the probability of drawing a green counter is
[tex]P(g)=\frac{10}{23}=\frac{\text{No of g counter}}{\text{Total no of counter}}[/tex]
[tex]\Rightarrow \frac{10}{23}=\frac{g+2}{g+2+r+4}[/tex]
[tex]\Rightarrow \frac{10}{23}=\frac{g+2}{g+r+6}[/tex]
[tex]\Rightarrow 10g+10r+60=23g+46[/tex]
[tex]\Rightarrow 10r+14=13g\ quad \ldots(ii)[/tex]
Substitute the value of g in equation (ii)[/tex]
[tex]\Rightarrow 10\times \frac{5}{4}g+14=13g[/tex]
[tex]\Rightarrow \frac{25}{2}g+14=13g[/tex]
[tex]\Rightarrow g=28[/tex]
Therefore [tex]r=35[/tex]
Thus there 28 green counter and 35 red counter

Francesca has already knit 28 centimeters of scarf, and can knit 7 centimeters each night. How many nights will Francesca have to spend knitting in order to knit a total of 42 centimeters of scarf?
Answer:
2 nights
Step-by-step explanation:
We need to find how many nights Francesca will have to spend to knit the rest of the scarf.
First, we have to find how much she has left to knit, and then find how many nights it will take her.
She has already knit 28 centimeters of scarf.
She wants to knit a total of 42 centimeters of scarf.
Therefore, the length of scarf left to knit is:
42 - 28 = 14 centimeters
She can knit 7 centimeters each night.
Therefore, the number of nights more she needs to knit 14 centimeters is:
14 / 7 = 2 nights
She will spend 2 nights to knit a total of 42 centimeters of scarf.
Find lim x -2 f(x) for: a . f(x) = 9 b. f(x) = x

Given the limit function
Lim x → 2: f(x)
1. When f(x) = 9
Then,
From limit theorem
Lim x → xo: K = K
Where k is a constant. Then, the limit of a constant is that constant.
Lim x → 2: 9 = 9
So limit is 9.
2. Lim x → 2: f(x)
Lim x → 2: x
When x = 2
Lim x → 2: 2 = 2
Then, x = 2.
Find the area of a semicircle
Answer:
18pi, or 56.52
Step-by-step explanation:
To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle
However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:
(pi x radius^2)/2 = area of semi-circle
(pi x 6^2)/2 = area of semi-circle
(36 x pi)/2 = area of semi-circle
18 x pi = area of semi-circle
18 x 3.14 = area of semi-circle
56.52 = area of semi-circle
The area of a circle is
[tex]\pi \: {r}^{2} [/tex]
So the area of a semicircle would be half of that, or
[tex] \frac{\pi}{2} {r}^{2} [/tex]
So just plug in the radius, six, to get this
[tex]18\pi[/tex]
A train leaves at 11.15 and arrives at its destination at 12.23. If the train travelled 95 km, what was it's average speed in km/h? Give your answer rounded to 1 dp.
Answer:
Average speed v = 83.8 km/h
Step-by-step explanation:
Given;
Distance travelled = 95 km
Time taken t = 12.23 - 11.15 = 1 hour 8 minutes
t = 1 + 8/60 hours = 1.133 hours.
Average speed v = distance travelled/time taken
substituting the values;
v = 95 km ÷ 1.133 hours
Average speed v = 83.8 km/h
