The volume of the right circular cylinder with a radius of 6 m and a height of 9 m is 1018 m².
The volume of a substance is the total space occupied by a three-dimensional object.
The volume of a right circular cylinder with a radius of r units and a height of h units is given by the formula V = πr²h square units.
We are asked to find the volume of the right circular cylinder with a radius of 6 m and a height of 9 m.
Substituting these values in the formula, we get Volume,
V = π(6)²(9) m² = 324π m² = 1017.876 m² ≈ 1018 m².
Therefore, the volume of the right circular cylinder with a radius of 6 m and a height of 9 m is 1018 m².

Which of the following equations could be used to solve the problem?
8 x - x = 70
x - 8 x = 70
x - 8 = 70
Answer:
8x - x = 70
Step-by-step explanation:
x equals 10 because,
8 x 10 = 80
and x = 10, so 80 - 10 = 70.

Answer:
10.4
Step-by-step explanation:
So an exponential equation with a decay can be expressed as: [tex]f(x)=a(1-r)^t[/tex] where r is the decay rate. In this case is decreasing at 4% each year, this means that the r is equal to 0.04 (divide the percent by 100 to convert to decimal). So the equation is going to be: [tex]f(x)=a(0.96)^t[/tex]. The reason this works is because whenever you decrease by x%, the new value is (1-x)%, which is expressed in the formula. But the reason the exponent is there is because after 1 year it's going to be 0.96a, but after two years, it's going to be 0.96 the previous year which is 0.96a, so after two years it's going to be 0.96(0.96a), and then the next year it's 0.96 of the second year, which is then 0.96(0.96(0.96a))... and so on. So the amount of 0.96 increases as t increases. the a is going to be the initial amount, since then t=0, 0.96^0 will be equal to 1, which makes the expression a(1), which is just a. So this gives you the complete equation: [tex]p(x)=13000(0.96)^t[/tex]
Now to find when it's equal to 8,500 you need to start by setting it equal to 8,500 so I'll work through each step
Original Equation:
[tex]p(x)=13000(0.96)^t[/tex]
Set the equation equal to 8,500
[tex]8500=13000(0.96)^t[/tex]
Divide both sides by 13,000
[tex]0.653846\approx 0.96^t[/tex]
Rewrite in logarithmic form
[tex]log_{0.96}0.653846=t[/tex]
If you're calculator allows you to enter the base when calculating log, but this expression into your calculator to calculate the value of t, otherwise use the change of base formula
[tex]\text{change of base formula: }log_ba = \frac{log(a)}{log(b)}[/tex]
[tex]t=\frac{log0.653846}{log0.96}\\[/tex]
[tex]t\approx\frac{-0.1845}{-0.0177}[/tex]

In the US, 47.3% of smart phones sold are made by Apple.
Suppose that 20,465 smart phone were sold in one day.
How many of those phones would be made by Apple?
9680 smart phones of total 20465 sold smart phones would be made by Apple.
Percentage is a mathematical measurement of any mathematical quantity or number or another measurement out of a total of 100.
Here given that in the US 47.3% of smart phones sold are made by Apple.
And in one day 20465 phones are sold.
So,
Out of 100 sold smartphones, 47.3 phones are made by Apple.
then out of 1 sold smartphone 47.3/100 phones are made by Apple.
Hence out of 20465 smartphones (10465*(47.3/100)) = 9679.945 phones are made by Apple.
Since number of sold smart phone cannot be in decimal number in real, it always a whole number.
Approximating to the nearest whole number we get out of 20465 sold smart phones in one day, 9679.945 = 9680 smart phones are made by Apple.

Find the midpoint of the line segment joining the points P1 and P2. P1 = (x, 8); P2 = (0, 9)
Answer:
(x/2 , 17/2)
Step-by-step explanation:
To find a midpoint, you average the x's and average the y's. Average them by adding the x-coordinates and divide by 2. Same with the y's.
The x's are x for P1 and 0 for P2.
x+0 / 2
=x/2
This will be the x-coordinate of the midpoint. Then for the y, use 8 and 9, the y's.
8+9 / 2
= 17/2
This will be the y-coordinate of the midpoint.
The midpoint is:
(x/2 , 17/2)
You could also divide 17/2 and get 8.5 then the midpoint would be:
(x/2 , 8.5)

can someone pls help find x and y
Answer:
x = 9 & y = 29
Step-by-step explanation:
Since we know that 7x is next to 117, that area will be equal to 180*,
7x + 117 = 180
7x = 180-117
7x=63
x=9
to find y, you can use the same method, just by finding the other angle inside. 53+7(9) + z = 180
53+63 = 180
116+z = 180
z = 180-116
z = 64.
Then we do
4y + 64 = 180
4y = 180-64
4y=116
y = 29

Tommy starts walking from school to home at the same time that his Dad starts walking from home to school. They both depart at 3:00 p.m. Tommy is walking at a speed of 1.35 meters per second, and his Dad is walking at a speed of 1.65 meters per second. The distance between home and school is 720 meters. At what time will they meet?
Answer:
They will meet at 3:04 p.m
Step-by-step explanation:
Since they are walking towards each other , that means we should add their speed together:
speed = 1.35 m/s + 1.65 m/s
= 3 m/s
Now that we have found the speed, we can calculate the time:
time = 720 meters / 3 m/s
= 240 seconds
= 4 minutes ( 240 seconds is 4 minutes)

B.
The graph of g(x) is a translation of the

C.
The graph of g(x) is a translation of the
graph of f(x) left 6 units.
Answer:
B. )The graph of g(x) is a translation of the graph of f(x) right 6 units.
Step-by-step explanation:
When a positive number is directly added to an "x" variable (usually inside of parentheses), the graph is shifted to the left that many units.
When a negative number is directly added to an "x" variable, the graph is shifted to the right that many units.
A graph shifts up or down when a positive or negative number is added to the overall function. For example, if the -6 were outside of the parentheses, the graph would be translated 6 units downwards.

Let v = leftanglebracket 3, negative 2 rightanglebracket. what is the approximate direction angle of v?
The approximate direction angle of v is 326°
Definition of Direction Angle
A vector's direction angle is the angle formed by the positive x-axis and the vector v. The arctangent of the ratio between the vertical and horizontal components of the vector, v=xi+yj, can be used to determine the direction angle, θ.
What is the direction angle of v?
Let θ be the direction angle of v or the angle mad by v with the horizontal line.
It is given that,
[tex]v = < 3, -2 >[/tex]
We know that,
θ = tan⁻¹([tex]\frac{y}{x}[/tex])
Here, we have y = -2 and x = 3. Hence, we get,
∴ θ = tan⁻¹[tex](\frac{-2}{3})[/tex]
⇒θ = tan⁻¹(0.66)
Hence the direction angle of v = 360 - tan⁻¹(0.66)
≈ 326°
Thus, the approximate direction angle of v is 326°.
