Step-by-step explanation:
Remember that 9! = 7! (8)(9)
write Substitute
7!(8)(9) for 9!
7!(8)(9)/ 7!= (8)(9)= 72
Answer: 72
Step-by-step explanation:
By definition, it is important to know that the factorial of a non-negative integer "n" is the product of all positive integers less than or equal to "n". This is expressed with an exclamation symbol (!):
[tex]n![/tex]
Then, the rule for this is the following:
[tex]n! = n *(n-1)![/tex]
Therefore, knowing this, you can evalute [tex]\frac{9!}{7!}[/tex] as following:
[tex]\frac{9*8*7*6*5*4*3*2*1}{7*6*5*4*3*2*1}=\frac{362,880}{5,040}=72[/tex]
What is the volume of a cylinder that has a diameter of 22km and a height of 7km
The volume of a cylinder with a given diameter and height using the formula V = πr²h is equal to 8471π km³.
The volume of the cylinder can be calculated using the formula for the volume of a cylinder: V = πr²h.
Given a diameter of 22 km (which means a radius of 11 km) and a height of 7 km, substitute these values into the formula to find the volume.
Substitute the values into the formula:
V = π × (11 km)²×7 km
Calculate the volume:
V = 8471π km³
Therefore, the volume is 8471π km³.
x divided by 12 = 12 divided by 72
Answer:
The equation to calculate what divided by 72 equals 12 is as follows:
X/72 = 12
Where X is the answer. When we solve the equation by multiplying each side by 72, you get get:
X = 864
Therefore, the answer to what divided by 72 equals 12 is 864.
I hope it helps!!
To find the value of x in the equation x/12 = 12/72, simplify 12/72 to get 1/6. Then, multiply both sides by 12 to solve for x, resulting in x = 2.
To solve the equation x divided by 12 = 12 divided by 72, we need to perform some algebraic manipulation to isolate x. First, rewrite the equation as a fraction:
x/12 = 12/72Next, simplify the fraction on the right-hand side:
12/72 = 1/6 (since 12 is 1/6th of 72)Now the equation looks like this:
x/12 = 1/6To solve for x, multiply both sides of the equation by 12:
x = 12 × 1/6x = 2So, the value of x is 2.
One number is 4 more than another. The difference between their squares is 128. What are the numbers?
Smaller number=___
Larger number=___
Answer:
14 and 18
Step-by-step explanation:
Small number : a
Larger number : a + 4
( a + 4 )^2 - a^2 = 128
a^2 + 8 a + 16 = 128
8 a = 128 - 16
a = 112 / 8
a = 14
And a + 4 = 18
What’s the smallest zero for the function h(x)=4x^2-8x-60
Answer:
-3
Step-by-step explanation:
In order to find the smallest zero, we will have to find out all the zeros of the function.
In case you are wondering what a zero is, it is the x-value or the domain intersections. The points where the parabola intersects the x-axis.
4x² - 8x - 60 = 0
Why zero?
We know that the parabola intersects the x-axis and when it does, the y-value is 0. h(x) is nothing but 'y'.
4(x²-2x-15) = 0 → I took the gcd as 4 and did it accordingly.
x² - 2x - 15 = 0 → Divide on both sides with 4
Now, what multiples to -15 but adds up to -2?
-5 and 3
x² + 3x - 5x - 15 → Grouping the terms
x ( x + 3 ) - 5 ( x + 3 ) → Taking the GCD in both groups
( x - 5 ) ( x + 3 ) = 0
x = 5 , -3
The smallest one out of these zeros is -3.
Hope it helps! :)
Cara plants 5 seeds in 2 minutes, while Wade plants 3 times as many seeds in half the time. How many seeds can they both plant together in 10 minutes?
Answer:
together they can plant 175 seeds in 10 minutes
Answer with Step-by-step explanation:
Cara plants 5 seeds in 2 minutes.
⇒ Cara plants 5×5 seeds in 2×5 minutes
⇒ In 10 minutes Cara plant 25 seeds.
Wade plants 3 times as many seeds in half the time as Cara.
⇒ Wade plants 3×5 seeds in 2/2 minutes
i.e. Wade plants 15 seeds in 1 minute.
In 1×10 minutes Wade plants 15×10 seeds
i.e. In 10 minutes Wade plants 150 seeds.
150+25=175
Hence, they can together plant 175 seeds in 10 minutes.

Answer:
the diagonals intersect at right angle i.e. slope of AC = - 1/ slope of BD and
Midpoint of AC = Z₁ is equal to Mid point of BD = Z₂
so, the parallelogram is rhombus.
Step-by-step explanation:
A parallelogram is a rhombus if diagonals intersect each other at right angle and the diagonals intersect at mid point.
We are given vertices:
A(-3,2)
B(-2,6)
C(2,7)
D(1,3)
The diagonals of the parallelogram will be:
AC and BD.
Slope of AC = y₂ - y₁ / x₂- x₁ where A = (-3,2) and C = (2,7)
Putting values:
Slope of AC = 7-2/2-(-3) = 5/5
Slope of AC = 1
Slope of BD = y₂ - y₁ / x₂- x₁ where B = (-2,6) and D = (1,3)
Putting values:
Slope of BD = 3-(6) / 1-(-2) = -3/3
Slope of BD = -1
AS, Slope of AC = - 1/ Slope of BD
So, the diagonals intersect and right angle.
Now finding the mid point Z₁ of AC and Z₂ of BD:
Midpoint of AC = Z₁ = A+C/2
Putting values:
=(-3,2) + (2,7) / 2
= (-1,9)/2
= (-1/2, 9/2)
Mid point of BD = Z₂ = B+D / 2
Putting values:
=(-2,6) + (1,3) / 2
= (-1,9)/2
= (-1/2, 9/2)
Midpoint of AC = Z₁ is equal to Mid point of BD = Z₂ i.e.
Z₁ = Z₂, the diagonals intersect at the same midpoint.
As,
the diagonals intersect at right angle i.e. slope of AC = - 1/ slope of BD and
Midpoint of AC = Z₁ is equal to Mid point of BD = Z₂
so, the parallelogram is rhombus.
What is the solution to the system of equations?
-3x-3y+2z=-7
z=1
-2x-3y+z=-6
A.(2, 1, –1)
B.(2, 1, 1)
C.(2, –1, 1)
D.(–2, 1, 1)
Answer:
B(2,1,1)
Step-by-step explanation:
Given:
-3x-3y+2z=-7
z=1
-2x-3y+z=-6
Let -3x-3y+2z=-7 be equation i, z=1 be equation ii and -2x-3y+z=-6 be equation iii
Solving the system of simultaneous equation by substituting value of z from equation ii to i , we get:
-3x-3y+2=-7
-3x-3y=-7-2
-3x-3y=-9 -------iv
Solving the system of simultaneous equation by substituting value of z from equation ii to iii, we get:
-2x-3y+1=-6
-2x-3y=-6-1
-2x-3y=-7
re-arranging the above equation, we get
3y=-2x+7
substituting value of 3y from above in equation iv, we get
-3x-(-2x+7)=-9
-3x+2x-7=-9
-x=-9+7
-x=-2
x=2
Now putting x=1 from above in equation v, we get
3y=-2(2) +7
3y=-4+7
3y=3
y=3/3
y=1
Hence the solution of system of given equations is (2,1,1) !
The answer is:
The correct option is B.(2, 1, 1)
Why?We can solve the system of equations by using the reduction method. The reduction method consists of reducing the variables in order to be able to calculate the other variables to finally calculate all the variables.
We are given the equations:
I.
[tex]-3x-3y+2z=-7[/tex]
II.
[tex]z=1[/tex]
II.
[tex]-2x-3y+z=-6[/tex]
Since the second equation is already solved, let's work with the first and third one, so, calculating we have:
[tex]\left \{ {{-3x-3y+2z=-7} \atop {-2x-3y+z=-6}} \right.[/tex]
Now, multiplying the first equation by -1 in order to reduce the variable "y", we have:
[tex]\left \{ {{3x+3y-2z=7} \atop {-2x-3y+z=-6}} \right\\\\x-z=1[/tex]
Then, substituting "z" into the obtained equation:
[tex]x-1=1\\x=1+1=2[/tex]
Now, substituting "x" and "z" into the first equation, we have:
[tex]-3x-3y+2z=-7[/tex]
[tex]-3*(2)-3y+2*(1)=-7[/tex]
[tex]-6-3y+2=-7[/tex]
[tex]-3y-4=-7[/tex]
[tex]-3y=-7+4[/tex]
[tex]-3y=-3[/tex]
[tex]y=\frac{-3}{-3}=1[/tex]
Hence, we have that the solutions are:
[tex]x=2\\y=1\\z=1[/tex]
So, the correct option is B.(2, 1, 1)

Find the equation in standard form of the line parallel to y=-1/5x+7 and passing through the point (-10,-3)
Answer:
the desired equation is y = (-1/5)x - 5.
Step-by-step explanation:
Parallel lines have the same slope. Here that slope is -1/5.
Let's use the slope-intercept form of the equation of a straight line:
y = mx + b
We know this new line passes through (-10, -3). Substitute -3 for y in y = mx + b, as well as -10 for x and -1/5 for m:
-3 = (-1/5)(-10) + b and solve for b:
-3 = 2 + b. Then b = -5, and the desired equation is y = (-1/5)x - 5.

What is the volume of a right circular cylinder with a radius of 3 in, and a height of 10 in?
Answer: 90[tex]\pi \\[/tex]
Step-by-step explanation:
Final answer:
The volume of a right circular cylinder with a radius of 3 inches and a height of 10 inches is calculated using the formula V = πr²h, which gives 282.74 cubic inches.
Explanation:
To calculate the volume of a right circular cylinder, you can use the formula V = πr²h, where 'V' is the volume, 'r' is the radius, and 'h' is the height of the cylinder. In this instance, the radius (r) is 3 inches, and the height (h) is 10 inches.
Using these values, you can plug them into the formula:
V = π × (3 in)² × 10 in
V = 3.14159 × 9 in² × 10 in
V = 3.14159 × 90 in³
V = 282.74 in³
Therefore, the volume of the cylinder is 282.74 cubic inches.

A paint can has a radius of 9.5 centimeters and a height of 28 centimeters. How
many cubic centimeters of paint will fill the can?
A) 31,739.12 cm3
B) 7934.78 cm3
C) 835.24 cm3
D) 3340.96 cm3
Answer: Option B.
Step-by-step explanation:
You need to use the formula for calculate the volume of a cylinder:
[tex]V=\pi r^2h[/tex]
Where "r" is the radius and "h" is the height.
You know that the paint can has a radius of 9.5 centimeters and a height of 28 centimeters:
[tex]r=9.5cm\\h=28cm[/tex]
Then, you need to substitute these values into [tex]V=\pi r^2h[/tex] to get the final result (In this case you can use [tex]\pi=3.14[/tex])
[tex]V=(3.14) (9.5cm)^2(28cm)[/tex]
[tex]V=7934.78cm^3[/tex]

which of the following is the best definition of a vertical asymptote
Answer:
Step-by-step explanation:
B
Answer: Option A: A vertical line that the line of the graph aproaches but never intecepts it.
Step-by-step explanation:
An asymptote is a graph line that aproaches infinitely to something (in this case a vertical line), but it does not touch it (so never intercepts the graph).
This means that the graph aproaches but never intercepts the line, so the correct answer is A.
The charge for a plumbing repair was $29.60 for parts, 1 1/4 hr. For labor at $56 per hr. And a $40 for the service call. What was the total cost (c) of the repair?
Answer: $139.60
Step-by-step explanation:
$40 for coming
$29.60 for parts
56 times 1.25 for labor = 70
70 + 29.6 + 40 = 139.6
The total cost (c) of the repair is given by the sum of the costs for parts, labor, and the service call that is [tex]\$139.60[/tex]
First, we calculate the labor cost. The plumber charged $56 per hour and worked for 1 1/4 hours. To find the total labor cost, we multiply the hourly rate by the time worked:
Labor cost = [tex]hourly \ rate \times \ time \ worked[/tex]
Labor cost =[tex]\$56 \times 1 1/4 hours[/tex]
Labor cost =[tex]\$56 \times (1 + 1/4) hours[/tex]
Labor cost = [tex]\$56 \times (5/4) hours[/tex]
Labor cost = [tex]\$56 \times 1.25 hours[/tex]
Labor cost = $70
Next, we add the cost for parts and the service call to the labor cost to find the total cost:
Total cost (c) = cost for parts + labor cost + service call cost
Total cost (c) = $29.60 + $70 + $40
Total cost (c) = $139.60

The triangle has side lengths of 25 in, 26in, and 3.5 in. Classify acute, obtuse, or right
Answer:
Obtuse triangle
Step-by-step explanation:
The longest side of the triangle is 26 in, so that will be the hypotenuse.
By an extension of the Pythagorean theorem:
Right triangle: a² + b² = c²Acute triangle: a² + b² > c²Obtuse triangle: a² + b² < c²Where a and b are the legs, and c is the hypotenuse.
Plug in: 3.5² + 25² ₙ 26²
Powers: 12.25 + 625 ₙ 676
Add: 637.25 < 676.
That means that this triangle is obtuse.
Answer:
Obtuse
Step-by-step explanation:
Using law of cosine, we can find the angle between the shorter sides:
c² = a² + b² − 2ab cos C
26² = 25² + 3.5² − 2(25)(3.5) cos C
cos C ≈ -0.221
C ≈ 102.8°
102.8° is greater than 90°, so the triangle is obtuse.

terms of degrees Celsius and degrees Fahrenheit.
c. What is the y-intercept of the line? Explain what the y-intercept
means in terms of degrees Celsius and degrees Fahrenheit.
Answer:
Part a) The equation of the line is
[tex]y-32=1.8(x-0)[/tex] or [tex]y=1.8x+32[/tex]
Part b) The slope of the line is [tex]m=1.8\frac{\°F}{\°C}[/tex]
Part c) The y-intercept is 32 (For a degrees Celsius equal to zero, the degrees Fahrenheit is equal to 32)
Step-by-step explanation:
Let
x ----> degrees Celsius
y ----> degrees Fahrenheit
we have the points
[tex](0,32),(100,212)[/tex]
Part a) Find the equation of the line
Find the slope m
[tex]m=(212-32)/(100-0)[/tex]
[tex]m=180/100[/tex]
[tex]m=1.8\frac{\°F}{\°C}[/tex]
The equation of the line into slope point form is equal to

we have
[tex]m=1.8\frac{\°F}{\°C}[/tex]
Point [tex](0,32)[/tex]
substitute
[tex]y-32=1.8(x-0)[/tex] ----> equation of the line into slope point form
[tex]y=1.8x+32[/tex] ---> equation of the line into slope intercept form
Part b) What is the slope of the line?
The slope of the line is [tex]m=1.8\frac{\°F}{\°C}[/tex]
That means
The rate of change of the temperature is 1.8 degrees Fahrenheit by each degree Celsius
Part c) What is the y-intercept of the line?
we have
[tex]y=1.8x+32[/tex] ---> equation of the line into slope intercept form
The y-intercept is 32
The y-intercept is the value of y when the value of x is equal to zero
That means

The distance between the points (4, 9) and (-2, 6) is approximately 6.71 units.
Identify the coordinates:
Let (x₁, y₁) = (4, 9) and (x₂, y₂) = (-2, 6).
Apply the distance formula:
The distance formula is given by:
d=√[tex]\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} )^{2} }[/tex]
Substitute the coordinates into the formula:
d= [tex]\sqrt{((-2)-4)^{2} +(6-9)^{2} }[/tex]²
Simplify the terms inside the square root:
d=[tex]\sqrt{(-6)^{2} +(-3)^{2} }[/tex]
d=[tex]\sqrt{36+9}[/tex]
d=[tex]\sqrt{45}[/tex]
Simplifying further, we get:
d≈6.71

What is the circumference of a circle with a diameter of 7 inches? (use for pi) PLEASE HELP ASAP
Answer:
C = 7pi = 21.98 inches
Step-by-step explanation:
The circumference of a circle is given by
C = pi * d
where d is the diameter
C = pi * 7
If we use 3.14 as an approximation for pi
C = 3.14 * 7
C =21.98 in
