Answer: 942.48 [tex]Units ^{3}[/tex]
Step-by-step explanation:
First we find the area of the base (the circle) the formula for that is [tex]\pi r^{2}[/tex]
the radius is 5 because it is half the diameter.
so our base is 78.54
then we multiply that by the height
so 78.54 times 12 = 942.48
If f(x) = 2x-3, find f(-2).
Answer:
F(2)=-7
Step-by-step explanation:
f(-2)=2x-3
you substitute the x on the positive 2
2(-2)=-4
-4-3-=7
-7
Hence the result of the function is x is -2 is -7
Given the function f(x) = 2x-3,
Domain of a function is the input value for which the function exists.
The range of the function is the output value for which the function exists
From the question, we can see that we are to find the resulting range if the domain of the function is -2.
To get f(-2), we will need to substitute x as 2 into the function as shown
f(-2) = 2(-2) - 3
f(-2) = -4 - 3
f(-2) = -7
Hence the result of the range with the domain of -2 is -7

Find the area of the figure. Round to the nearest tenth
Common difference between 31,26,21,16
I like to work backwards to see if the common difference is the same.
So I take 16 and work to the left.
So I say 16 - 21 which is -5.
Then I do 21 - 26 which is -5.
Finally, 26 - 31 which is -5.
So what I am doing here is just taking the number that is on the right and subtracting it by the number that appears to the left of it.
Notice that I always get -5 and that has to be because in order for this to have a common difference, the result must always be the same if you are working with the method I used above.
So, our common difference is -5.
The answers I don’t really understand the question
For step one, they want you to factor 5,000 into a 5 and ?. To find the missing value, we can divide:
5,000 / 5 = 1,000
So, 1000 goes in the first blank.
For step two, 1,000 also goes in the second blank since the first 2 numbers are being multiplied.
For step three, multiply the last two numbers.
30 * 1000 = 30,000
So, 30000 goes in the last blank.
Best of Luck!
Answer: 30000 goes in the last one

Step-by-step explanation:
simplify
Final answer:
The equivalent expression for (3x^2y)(10x^5y^3) is 30x^7y^4, obtained by multiplying the coefficients and adding the exponents of like bases.
Explanation:
The question asks for the equivalent expression of the product (3x^2y)(10x^5y^3).
To find the equivalent expression, we need to apply the properties of exponents, which state that when multiplying two powers with the same base, we add the exponents. We can also multiply the coefficients in a usual way. Let's break it down into steps:
Multiply the coefficients (numbers outside the exponents): 3 × 10 = 30.
Add the exponents of x: x^2 × x^5 = x^(2+5) = x^7.
Add the exponents of y: y^1 × y^3 = y^(1+3) = y^4.
Combine the results: 30x^7y^4.
Therefore, the equivalent expression for (3x^2y)(10x^5y^3) is 30x^7y^4.

A ball is projected upward from the ground. Its distance in feet from the ground in t seconds is given by s left parenthesis t right parenthesis equals negative 16 t squared plus 126 t. At what times will the ball be 211 feet from the ground?
Answer:
t = 5.46 secs and t = 2.42 secs
Step-by-step explanation:
The distance of the ball from the ground is given by:
[tex]s(t) = -16t^2 + 126t[/tex]
When the ball is at a distance 211 ft from the ground, that means s(t) = 211 ft. we need to find t:
[tex]211 = -16t^2 + 126t[/tex]
[tex]=> 16t^2 -126t + 211 = 0[/tex]
Using the quadratic formula:
[tex]t = \frac{-b + \sqrt{b^2 - 4ac} }{2a}[/tex] and [tex]t = \frac{-b - \sqrt{b^2 - 4ac} }{2a}[/tex]
where a = 16, b = 126 and c = 211
Hence:
[tex]t = \frac{-(-126) + \sqrt{(-126)^2 - 4(16)(211)} }{2(16)}[/tex] and [tex]t = \frac{-(-126) - \sqrt{(-126)^2 - 4(16)(211)} }{2(16)}[/tex]
[tex]t = \frac{126 + \sqrt{15876 - 13504} }{32}[/tex] and [tex]t = \frac{126 - \sqrt{15876 - 13504} }{32}[/tex]
[tex]t = \frac{126 + \sqrt{2372} }{32}[/tex] and [tex]t = \frac{126 - \sqrt{2372} }{32}[/tex]
[tex]t = \frac{126 + 48.703 }{32}[/tex] and [tex]t = \frac{126 - 48.703 }{32}[/tex]
[tex]t = \frac{174.703}{32}[/tex] and [tex]t = \frac{77.297}{32}[/tex]
=> t = 5.46 secs and t = 2.42 secs
This means that the ball will be at 211 feet at two different times, first, after 2.42 seconds and then after 5.46 seconds.
This makes sense because the ball is projected upwards, which means that when going up, it attains 211 feet and also, when coming back down, it also attains 211 feet.
To determine the time when the ball is 211 feet off the ground, set s(t) equal to 211 and solve the resulting quadratic equation (-16t^2 + 126t - 211 = 0) using the quadratic formula. Discard the negative solution as it represents a time before launch.
Explanation:In response to the given question, we need to determine the time when the ball is 211 feet from the ground given the formula s(t)=-16t^2 + 126t. This is a quadratic equation which can be solved for t using the quadratic formula.
First, we need to set the equation equal to 211 to solve for when the ball is this distance off the ground. So, -16t^2 + 126t = 211. Rearrange the equation: -16t^2 + 126t - 211 = 0.
Now, apply the quadratic formula t = [-b ± sqrt(b^2 - 4ac)] / 2a, where a = -16, b = 126, and c = -211. This yields two solutions corresponding to the times at which the ball is 211 feet from the ground. The negative solution represents a moment before the ball is launched, hence we discard it. The positive value is the time at which the ball attains a height of 211 feet.

Step-by-step explanation:
Each half of the drawbridge is about 284 feet long. How high does the drawbridge rise when x is 30?? The drawbridge rises about feet. Question 2 How high does the drawbridge rise when x is 45?? Round the answer to the nearest hundredth. The drawbridge rises about feet. Question 3 How high does the drawbridge rise when x is 60? ? Round the answer to the nearest hundredth. The drawbridge rises about feet.
Answer:
height = 142.00 ft
height ≈ 200. 82 ft
height ≈ 245.95 ft
Step-by-step explanation:
The picture below represent the image of the draw bridge. The illustration will form a right angle triangle. The hypotenuse is each half of the drawbridge which is 284 ft long. The opposite side of the triangle is facing the drawbridge half leg and the adjacent side is horizontal length. This is the side that made the angle with the drawbridge half leg(hypotenuse).
The question ask us to find the height of the drawbridge when it rise which is the opposite sides of the triangle when the angle is 30° , 45° and 60°.
Using SOHCAHTOA principle,
Angle 30°
sin 30° = opposite/hypotenuse
sin 30° = height/284
cross multiply
height = 0.5 × 284
height = 142.00 ft
Angle 45°
sin 45° = height/284
height = 284 × 0.70710678118
height = 200.818325857
height ≈ 200. 82 ft
Angle 60°
sin 60 = height/284
cross multiply
height = 0.86602540378 × 284
height = 245.951214675
height ≈ 245.95 ft
The question asks about the height a drawbridge rises at different angles. This is a trigonometry problem that can be solved by using the sine of the angle to calculate the height of the bridge when raised. The height corresponds to the 'opposite' side in a right triangle formed by the raised drawbridge.
Explanation:This question appears to be asking about how high a drawbridge rises based on an angle, x, which is a trigonometry problem. Assuming that the drawbridge forms a right triangle when it rises, the height can be calculated using the sine of the angle, x. Sine of x is equal to the opposite side (height of the bridge when it is raised) over the hypotenuse (half of the drawbridge's length).
Applying these trigonometric principles, calculations for each scenario would look like the following:
For x = 30 degrees: Height = sin(30) * 284 feet = 142 feet. For x = 45 degrees: Height = sin(45) * 284 feet = 200.71 feet (rounded to the nearest hundredth). For x = 60 degrees: Height = sin(60) * 284 feet = 245.98 feet (rounded to the nearest hundredth). Learn more about Trigonometry here:

Mark, Paul and Brian share some sweets in the ratio 1:3:5. Mark gets 14 sweets. How many did Brian get?
Answer:
70
Step-by-step explanation:
mark = 1 1 times 14 = 14
Brian = 5 5 times 14 = 70
Brian receives 70 sweets, as Mark's 14 sweets represent 1 part of the ratio 1:3:5, indicating that 1 part equals 14 sweets and Brian's 5 parts equal 70 sweets.
Mark, Paul, and Brian share sweets in a ratio of 1:3:5, which means that for every sweet Mark gets, Paul gets 3, and Brian gets 5. Since Mark gets 14 sweets, we can use this information to calculate how many sweets Brian gets. First, let's find out what one 'part' of the ratio is worth by dividing the number of sweets Mark gets by his ratio number:
Mark's sweets (14) / Mark's ratio (1) = 14 sweets per ratio part.
Next, determine Brian's share by multiplying the sweets per ratio part by Brian's ratio number:
Brian's share = sweets per ratio part (14) * Brian's ratio (5) = 70 sweets.
Therefore, Brian gets 70 sweets.
