Find the volume of a cylinder if it is 2 feet tall and has a diameter of 1.5. Use 3.14 for pi.
Answer:
3.5325
Step-by-step explanation:
V = 3.14*(.75^2)(2)
You divide the diameter by 2 to get the radius which is 1.5/2 =.75
r=.75
h=2
and you use the equation for volume of cylinder which is V = pi x radius squared x height

Answer:
A. 45°
Step-by-step explanation:
The sum of all the angles in a quadrilateral must be 360. This means that you need to subtract 135, 90, and 90 from 360 to get the unknown angle.
360 - 90 - 90 - 135 = 45°
What could this answer be??
The number in the parentheses is the rate of change. Because this number is less than 1 it is a decrease, so it is a decay.
The percent decrease is 1 - 0.63 = 0.37 = 37% decrease
Find a degree 3 polynomial with real coefficients having zeros 5 and 4i and a lead coefficient of 1. Write P in expanded form
Given:
The degree of the polynomial = 3
Leading coefficient = 1
Zeros of the polynomial are 5 and 4i.
To find:
The expanded form of the polynomial.
Solution:
According to the complex conjugate root theorem, if a+ib is a zero of a polynomial, then a-ib is also a zero of that polynomial.
Here, zeros of the polynomial are 5 and 4i. It means the third zero of the polynomial is -4i. So, the factors of the polynomial are [tex](x-5),(x-4i),(x+4i)[/tex].
The required polynomial is the product of its all factor and a constant which is equal to the leading coefficient. Here, the constant is 1. So, the required polynomial is
[tex]P(x)=1(x-5)(x-4i)(x+4i)[/tex]
[tex]P(x)=(x-5)(x^2-(4i)^2)[/tex]
[tex]P(x)=(x-5)(x^2+16)[/tex] [tex][\because i^2=-1][/tex]
[tex]P(x)=(x-5)(x^2+16)[/tex]
On further simplification, we get
[tex]P(x)=x^3+16x-5x^2-80[/tex]
[tex]P(x)=x^3-5x^2+16x-80[/tex]
Therefore, the required polynomial P is [tex]P(x)=x^3-5x^2+16x-80[/tex].

what is the sum of exterior angles of any polygon
Answer:
the sum of all exterior angles equal 360
Step-by-step explanation:
Summed, the exterior angles equal 360 degrees. A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees.
Which is the solution to the system 3x+y=8 and 7x−4y=25
Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
3x + y = 8 → (1)
7x - 4y = 25 → (2)
Multiplying (1) by 4 and adding to (2) will eliminate the y- term
12x + 4y = 32 → (3)
Add (2) and (3) term by term to eliminate y
19x + 0 = 57
19x = 57 ( divide both sides by 19 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
3(3) + y = 8
9 + y = 8 ( subtract 9 from both sides )
y = - 1
solution is (3, - 1 )

find the value of x. round to the nearest tenth.
Answer: 10.2 (nearest tenth)
Step-by-step explanation:
For this question, you have to find out whether you are using Sin, Cos, or Tan.
For that, you can use SOH CAH TOA to help you.
SOH-the 'S' is for Sin then the 'O' and the 'H' stands for Opposite over Hypotenuse.
CAH-the 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA-the 'T' is for Tan then then 'O' and the 'A' is for Opposite over Adjacent.
Because you have the Adjacent (the side next to the 22°) and the Hypotenuse (the side opposite the right angle) you would be using Cos.
First you would write:
Cos 22=x/11
Then because you want x on it's own you would do the inverse so you would times Cos 22 by 11.
This would be written as:
11 Cos 22=x
So, x=10.2 (nearest tenth)
Hope this helps :)

A man measures the angle of elevation between the ground and a building 800ft away to be 30
degrees. How tall is the building?
Answer:
461.88 feet
We are given the opposite and adjacent of 30.
Tan (30) = opposite / adjacent
Tan (30) = x / 800
X = 800 x Tan(30)
X = 461.88
- Use a calculator to calculate "Tan(30)".
- The exact answer is 461.880215
The height of the building will be equal to 461.88 feet.
What is trigonometry?
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
We are given the opposite and adjacent of 30.
Tan (30) = opposite / adjacent
Tan (30) = x / 800
X = 800 x Tan(30)
X = 461.88
Therefore the height of the building will be equal to 461.88 feet.

Answer:

Step-by-step explanation:
The slope of the line is 3 which represents that the time is rising as the distance increases.
What is the slope of the line?A line's slope is defined as the ratio of the change in y-coordinates of two points on the line to the change in x-coordinates of the same two places.
The slope of the line that passes through the pair of points (3, 6) and (1, 3) is calculated as follows:
slope = (6 - 3) / (3 - 2)
slope = (3) / (1)
slope = 3
In this case, the slope of 3 means that the time is rising as the distance increases.
Therefore, the slope of the line that passes through the pair of points (3, 6) and (1, 3) is 3.

If a fair die is rolled twice and two numbers X1=result of the first roll and X2=result of the second roll are obtained. Given that X1+X2=7, what is the probability that X1 =4 or X2 =4
Answer:
P = 2/3 = 0.67
Step-by-step explanation:
Assuming that X1 + X2 = 7
The total number of outcomes such that X1 + X2 = 7 are:
X1 = 3, X2 = 4
X1 = 4, X2 = 3
X1 = 1, X2 = 6
X1 = 6, X2 = 1
X1 = 2, X2 = 5
X1 = 5, X2 = 2
So there are 6 total outcomes such that X1 + X2 = 7
Now, the probability that X1 = 4 is equal to the quotient between the number of outcomes where X1 = 4 (only one outcome) and the total number of outcomes (6)
Then:
p = 1/6
And the probability that X2 = 4 is calculated in the same way, then the probability is:
q = 1/6
Now, the probability that X1 = 4 or X2 = 4 is the sum of both probabilities we've found above, then:
P = p + q = 1/6 + 1/6 = 2/6 = 2/3 = 0.67

A $100 tablet is marked up by 10% and then the new price is marked down by 10%. What is the final price?
Answer:
$99
Step-by-step explanation:
So the initial price of the tablet was $100. It was marked up by 10% and then marked down by 10%. We are asked to find the final price.
To find the final price, lets first find the price after the tablet price was marked up by 10%. This means that the tablet price increased by 10%. To find the price, we can add 10% of the new original price (or 10% times $100) original price ($100):
$100 + ($100 × 0.1) = $100 + $10 = $110
We could have also multiplied $100 by 1.1 (or 1 + 10%) to find the new price.
So now we know that the new price after the tablet is marked up by 10% is $110. Now, to find the final price, we have to find the price after the new price is marked down by 10%. We can do this by taking the new price ($110) and subtracting 10% of the new price (or 10% times $110):
$110 - ($110 × 0.1) = $110 - $11 = $99
So the final price of the tablet would be $99.
