Step-by-step explanation:
volume =πr²h=π×4²×8=128π in³
Finding the volume of a cylinder involves its formula: b*h=v. In the case of a cylinder and even cones, your base is a circle, and therefore is the area of said circle.
What you first want to do is find the area of the circle, to do that you need to know the formula which is r^2*pi. A cylinder has two congruent sides which are the circles, therefore the radius of one circle is the same as the other. Now use the radius of the circle on the top of the cylinder and square it. 4^2=16. Next we need to multiply 16 by pi (pi can be multiplied like a variable and just added next to 16. Therefore 16*pi= 16π.
Next now that you have your base (16π) you must multiply by your height which is 8 in this case (the length between the two circles). 16π*8 and now multiply as it it were two terms (a variable and whole number) so 16π*8= 128π

Answer:

make sure it's a fraction
Answer:
27 11/4x
Step-by-step explanation:
First we add the similar parts of the expression.
Whole numbers
6 + 9 + 5 + 7 = 27
Then we add the fractions that dont have x.
We only add the numerators (2 and 3) and dont change the denominators (4)
2/4 + 3/4 = 5/4
Now we add the ones with x.
5/4 + 3/4x + 3/4x = 11/4x
Now we combine those parts together, making

Answer:
4.25
Step-by-step explanation:
You're having to use the method P.E.M.D.A.S (Parenthesis, Exponents, Multiplication, Division, Adding and Subtracting) each one going in order.
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
17-5*(2*x-9)-((6*x-10)+4)=0
(17 - 5 • (2x - 9)) - (6x - 6) = 0
3.1 Pull out like factors :
68 - 16x = -4 • (4x - 17)
-4 • (4x - 17) = 0
4.1 Solve : -4 = 0
A a non-zero constant never equals zero.
4.2 Solve : 4x-17 = 0
Add 17 to both sides of the equation :
4x = 17
Divide both sides of the equation by 4:
x = 17/4 = 4.250
x = 17/4 = 4.250

Answers
Answer:
Answer A: y-intercept is 2 and slope is -3.
Step-by-step explanation:
It's immediately apparent that the line crosses the y-axis at (0, 2), so the y-intercept is 2. Also apparent is the negative slope. Thus, we choose Answer A: y-intercept is 2 and slope is -3.

Answers
Answer:
(38/7, 0)
Step-by-step explanation:
y-4=7(x-6)
First, put the equation in y=mx+b form
Hence, isolate y:
y - 4 + 4 = 7(x - 6) + 4 ==> add 4 on both sides to isolate y
y = 7(x - 6) + 4
y = 7x - 7*6 + 4 ==> Distributive property: distribute 7 to x and 6
y = 7x - 42 + 4 ==> simplify
y = 7x - 38
0 = 7x - 38 ==> set y=0 since x-intercept is when y=0
38 = 7x ==> Now divide each side by 7 to isolate x
x = 38/7 ==> (38/7, 0)

Answer:
Step-by-step explanation: to find the y intercept let y=0
y-4=7(x-6)
Substitute y=0
0-4=7(x-4)
-4=7*x-28..........expand the bracket
-4=7x-28
Get x term on its own
Add 28 to both sides
-4+28=7x-28+28
24=7x
Divide both sides by 7

Which figure has exactly one line of symmetry? A rhombus, pentagon, rectangle and triangle are shown. A. Rhombus B. Pentagon C. Rectangle D. Triangle
Answers
Answer: The figure that has exactly one line of symmetry is B. Pentagon.
Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.
Using either method, we can see that:
A. Rhombus has two lines of symmetry: one diagonal and one vertical.
C. Rectangle has two lines of symmetry: one horizontal and one vertical.
D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.
B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.
Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.

Firstly, you have to understand that if you talk about slope is a similar word gradient of the graph. So if you are calculating slope you have to use gradient formula:
m= Y2-Y1
X2-X1
therefore, in order for you getting first box & second box you have to use this formula above.
First box answer is:
Points fromthegraph (-2:-2) & (-3:-3)
m= Y2-Y1
X2-X1
m = -3-(-2)
-3-(-2)
m = 1
Second box answer is:
Points fromthegraph (3:3) & (4:4)
m= Y2-Y1
