find the volume of a cylinder with diameter 8 inches and height 9 1/2 inches
Answer:
[tex]V=152\pi in^{2}[/tex] in terms or pi
[tex]V=477.52in^{2}[/tex] simplified
Step-by-step explanation:
To solve this, we are using the Cylinder's volume formula:
[tex]V=\pi r^{2} h[/tex]
where
[tex]V[/tex] is the volume of the cylinder
[tex]r[/tex] is the radius of the cylinder
Remember that radius is half the diameter, so we can divide the diameter of our cylinder by 2 to find its radius: [tex]r=\frac{d}{2} =\frac{8in}{2} =4in[/tex]. Now, 9 1/2 inches is 9 and a half inches, so [tex]h=9.5in[/tex].
Replacing values:
[tex]V=\pi (4in)^{2} (9.5in)[/tex]
[tex]V=\pi (16in^{2})(9.5in)[/tex]
[tex]V=152\pi in^{2}[/tex]
[tex]V=477.52in^{2}[/tex]
We can conclude that the volume of our cylinder is [tex]V=152\pi in^{2}[/tex] in terms of pi, or [tex]V=477.52in^{2}[/tex] simplified.
Answer:
[tex]V=477.5in^3[/tex]
Step-by-step explanation:
The volume of a cylinder can be calculated using the formula;
[tex]V=\pi r^2h[/tex]
where the radius is half of the diameter of the circle.
[tex]r=\frac{8}{2} =4in.[/tex]
The height of the cylinder is
[tex]h=9\frac{1}{2}=\frac{19}{2}in.[/tex]
We substitute the values into the formula to obtain;
[tex]V=\pi\times 4^2\times \frac{19}{2}[/tex]
[tex]V=477.5in^3[/tex]
correct to the nearest tenth

Two cars simultaneously left Points A and B and headed towards each other, and met after 2 hours and 45 minutes. The distance between points A and B is 264 miles. What is the speeds of the cars, if one of the cars travels 14 mph faster than the other?
Please help
This is the only problem of my homework that I don't understand
The answers are:
[tex]FirstCarSpeed=41mph\\SecondCarSpeed=55mph[/tex]
Why?To calculate the speed of the cars, we need to write two equations in order to create a relation between the two speeds and be able to calculate one in function of the other.
So, let be the first car speed "x" and the second car speed "y", writing the equations we have:
For the first car:
[tex]x_{FirstCar}=x_o+v*t[/tex]
For the second car:
We know that the speed of the second car is the speed of the first car plus 14 mph, so:
[tex]x_{SecondCar}=x_o+(v+14mph)*t[/tex]
Now, we already know that both cars met after 2 hours and 45 minutes, and the distance between A and B is 264 miles, so, we can calculate the relative speed between both cars.
If the cars are moving towards each other the relative speed will be:
[tex]RelativeSpeed=FirstCarSpeed-(-SecondCarspeed)\\\\RelativeSpeed=x-(-x-14mph)=2x+14mph[/tex]
So , since we know that they covered a combined distance equal to 264 miles in 2 hours + 45 minutes, we have:
[tex]2hours+45minutes=120minutes+45minutes=165minutes\\\\\frac{165minutes*1hour}{60minutes}=2.75hours[/tex]
Writing the equation:
[tex]264miles=(2x+14mph)*t\\\\264miles=(2x+14mph)*2.75hours\\\\2x+14mph=\frac{264miles}{2.75hours}\\\\2x=96mph-14mph\\\\x=\frac{82mph}{2}=41mph[/tex]
Therefore, the speed of the first car is equal to 41 mph.
Now, for the second car we have that:
[tex]SecondCarSpeed=FirstCarSpeed+14mph\\\\SecondCarSpeed=41mph+14mph=55mph[/tex]
We have that the speed of the second car is equal to 55 mph.
Hence, the answers are:
[tex]FirstCarSpeed=41mph\\SecondCarSpeed=55mph[/tex]

Given: E, F, Q, D∈k(O),
O ∈ ED , m∠DFQ = 10°,
m EF = 28°
Find: Angles of △EFQ
Answer:
The angles are m∠EQF=14°, m∠EFQ=90° and m∠QEF=76°
Step-by-step explanation:
Given the figure in which m∠DFQ = 10°, m∠EOF = 28°
we have to find the angles of △EFQ
m∠EOF = 28°
By theorem angle subtended at the centre is twice the angle subtended at the circumference
⇒ m∠EQF=14°
As angle ∠EFQ is the angle in the semicircle
∴ ∠EFQ=90°
In ΔEFQ, by angle sum property of triangle
m∠EFQ+m∠FQE+m∠QEF=180°
90°+14°+m∠QEF=180°
m∠QEF=180°-90°-14°=76°
Hence, m∠EFQ=90° and m∠QEF=76°
To find the missing angle in triangle △EFQ, we used the fact that the sum of angles in a triangle is always 180°. Therefore, m∠EQF is found to be 142°, making the angles of the triangle 10°, 28°, and 142°.
Explanation:This problem deals with finding the measurements of angles in a triangle. In this case, the triangle is △EFQ, and we are given that m∠DFQ = 10° and m∠EF = 28°. The sum of the angles in a triangle always equals 180°. So, the third angle, m∠EQF, can be found by subtracting the given angles from 180°.
To calculate, follow these steps:
First, add the given angles: 10° + 28° = 38°.Next, subtract the sum of the given angles from 180°: 180° - 38° = 142°.Therefore, m∠EQF = 142°. So, the angles of triangle △EFQ are 10°, 28°, and 142°.

A.
A. cubic binomial
B. quadratic monomial
C. cubic trinomial
D. linear trinomial
Answer: OPTION C
Step-by-step explanation:
To express a polynomial in Standard form, you need to see the exponent of each term of the polynomial and then order the polynomial from highest exponent to lowest exponent.
Therefore, for the polynomial [tex]5a^2 + 3a^3 + 1[/tex], you get:
[tex]3a^3 +5a^2 +1[/tex]
The highest exponent gives you the degree of the polynomial. In this case, the highest exponent is 3, then it is a polynomial of degree 3 or a cubic polynomial.
When a polynomial has three terms, is called "trinomial". Since this polynomial has three terms, it is a trinomial.
Therefore, the you can classify it as:

lf 4 pounds of birdseed cost
$6.95, about how much does 1 ounce
cost?
Answer:
$1.01
Step-by-step explanation:
To find the cost of one ounce of birdseed, first convert the weight to ounces (4 pounds equals 64 ounces) and then divide the total cost by the total number of ounces. The result is approximately $0.11 per ounce.
First, we need to convert the weight from pounds to ounces since there are 16 ounces in 1 pound. So, 4 pounds is equivalent to 4 × 16, which equals 64 ounces.
Now, if 4 pounds (or 64 ounces) of birdseed cost $6.95, we want to find the cost of one ounce. To do this, we divide the total cost by the total number of ounces:
$6.95 / 64{ ounces} = approximately $0.10859375 { per ounce}
This result is the cost per ounce. So, the approximation for the cost of 1 ounce of birdseed is roughly $0.11 (rounded to 2 decimal places).

Next one (x+5)(2x-1)=0
and
So, the solution set for the quadratic equation (x+5)(2x-1)=0 is
Next one (-2x+1)(-x+5)=0
and
So, the solution set for the quadratic equation (-2x+1)(-x+5)=0 is : therefore, we are going the select this one.
Next one (x+1/2)(x+5)=0
and
So, the solution set for the quadratic equation (x+1/2)(x+5)=0 is
Finally, our last one (-2x+1)(x-5)=0
and
So, the solution set for the quadratic equation (-2x+1)(x-5)=0 is ; this is also a correct answer, make sure to select this one too.
We can conclude that both (-2x+1)(-x+5)=0 and (-2x+1)(x-5)=0 quadratic equation have as solution set.

g(1)=51 g(n)=g(n-1)+2 fina an explicit formula for g(n)
Answer:
g(n) = 2n+49
Step-by-step explanation:
Since g(1) = 51, then g(1)+2=g(2) or g(2)=53. So the formula for g(n) is
g(n) = 49+2n
The explicit formula for g(n) will be g(n) = 2n + 49.
What is a function?Functions are found all across mathematics and are required for the creation of complex relationships.
g(1) = 51 and g(n) = g(n – 1) + 2
Since g(1) = 51, then g(1) + 2= g(2) or g(2) = 53.
So the formula for g(n) will be
g(n) = 49 + 2n

Which of the following are factors of the equation when written in factored form
Answer:
B and D
Step-by-step explanation:
Given
2a² + 8a - 15 = 3a - 3 ( subtract 3a - 3 from both sides )
2a² + 5a - 12 = 0 ← in standard form
To factorise the quadratic
Consider the factors of the product of the a² term and the constant term which sum to give the coefficient of the a term, that is
product = 2 × - 12 = - 24 and sum = + 5
The factors are + 8 and - 3
Use these factors to split the a- term
2a² + 8a - 3a - 12 = 0 ( factor the first/second and the third/fourth terms )
2a(a + 4) - 3(a + 4) = 0 ← factor out (a + 4) from each term
(a + 4)(2a - 3) = 0 ← in factored form

A fourth degree polynomial has real roots at 0,3 a double real root at -1 and passes through point 2,12 what is the equation for the function
Answer:
y=x^2-3x
Step-by-step explanation:
Final answer:
A fourth degree polynomial with real roots at 0, 3 and a double real root at -1 passes through the point (2, 12). The equation for the function is -2x(x - 3)(x - 3)(x + 1).
Explanation:
A fourth degree polynomial with real roots at 0, 3 and a double real root at -1 can be expressed as:
f(x) = a(x - 0)(x - 3)(x - 3)(x + 1)
To find the value of 'a', we can substitute the point (2, 12) into the equation:
12 = a(2 - 0)(2 - 3)(2 - 3)(2 + 1)
12 = -6a
a = -2
So, the equation for the function is:
f(x) = -2x(x - 3)(x - 3)(x + 1)
