648π cm³
Step-by-step explanation:
Hi there!
The formula to find the volume of a cylinder is r²πh, where r is the radius, π is pi, and h is the height
first, let's find the area of the circle (r²π)
we are given that the radius is 9 cm
so we can square the 9, which is the same as multiplying it by itself
(9*9)=81π
Your answers leave everything in pi, so we can leave the area of the circle as is :)
now, multiply 81π by the height, which is given as 8 cm
81π*8=648π
therefore the answer is 648π cm³

Sally and Suzie both agree that m∠A + m∠B = 180⁰.
Sally claims ∠A and ∠B are supplementary.
Suzie claims ∠A and ∠B are not supplementary because they are not adjacent.
Who is correct?
Answers
Explanation:
The angles do not need to be touching, or adjacent, for them to be supplementary. They simply need to add to 180 degrees.
We have 70+110 = 180, so that proves the angles are supplementary. They can be rearranged to glue together to form a straight angle.
If the angles were supplementary and adjacent, then we can consider them as a linear pair. This is possibly what Suzie might be thinking about.

administrators after two hours, at which time both arms
are assessed for sun exposure.
O The volunteers are the explanatory variables.
O. The brands of sunscreen are the response
variables.
O The amount of time in the sun is the response
variable.
O The brands of sunscreen are the explanatory
variables.
Answers
Answer:
d
Step-by-step explanation:
The correct option is C. The amount of time in the sun is the response
variable.
Given, An experiment is conducted to measure the effectiveness of a brand of sunscreen.
A response variable measures an outcome of a study. An explanatory variable attempts to explain the observed outcomes. The explanatory variable is usually called independent and the response variable is called dependent.
From the above definition it is clear that A response variable is dependent quantity so here in question, option c states that the amount of time in the sun is the response variable which is right because it is totally depend on the brand of sunscreen.
Hence the correct option is C. The amount of time in the sun is the response
variable.

Trying to factor by splitting the middle term
3.1 Factoring 5x2+6x+4
The first term is, 5x2 its coefficient is 5 .
The middle term is, +6x its coefficient is 6 .
The last term, "the constant", is +4
Step-1 : Multiply the coefficient of the first term by the constant 5 • 4 = 20
Step-2 : Find two factors of 20 whose sum equals the coefficient of the middle term, which is 6 .
-20 + -1 = -21
-10 + -2 = -12
-5 + -4 = -9
-4 + -5 = -9
-2 + -10 = -12
-1 + -20 = -21
1 + 20 = 21
2 + 10 = 12
4 + 5 = 9
5 + 4 = 9
10 + 2 = 12

Parabola, Finding the Vertex:
4.1 Find the Vertex of y = 5x2+6x+4
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 5 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is -0.6000
Plugging into the parabola formula -0.6000 for x we can calculate the y -coordinate :
y = 5.0 * -0.60 * -0.60 + 6.0 * -0.60 + 4.0
or y = 2.200
Solve Quadratic Equation by Completing The Square
4.2 Solving 5x2+6x+4 = 0 by Completing The Square .
Divide both sides of the equation by 5 to have 1 as the coefficient of the first term :
x2+(6/5)x+(4/5) = 0
Subtract 4/5 from both side of the equation :
x2+(6/5)x = -4/5
Now the clever bit: Take the coefficient of x , which is 6/5 , divide by two, giving 3/5 , and finally square it giving 9/25
Add 9/25 to both sides of the equation :
On the right hand side we have :
-4/5 + 9/25 The common denominator of the two fractions is 25 Adding (-20/25)+(9/25) gives -11/25
So adding to both sides we finally get :
x2+(6/5)x+(9/25) = -11/25
Adding 9/25 has completed the left hand side into a perfect square :
x2+(6/5)x+(9/25) =
(x+(3/5)) • (x+(3/5)) =
(x+(3/5))2
Things which are equal to the same thing are also equal to one another. Since
x2+(6/5)x+(9/25) = -11/25 and
x2+(6/5)x+(9/25) = (x+(3/5))2
then, according to the law of transitivity,
(x+(3/5))2 = -11/25
We'll refer to this Equation as Eq. #4.2.1
The Square Root Principle says that When two things are equal, their square roots are equal.
Note that the square root of
(x+(3/5))2 is
(x+(3/5))2/2 =
(x+(3/5))1 =
x+(3/5)
Now, applying the Square Root Principle to Eq. #4.2.1 we get:
x+(3/5) = √ -11/25
Subtract 3/5 from both sides to obtain:
x = -3/5 + √ -11/25
In Math, i is called the imaginary unit. It satisfies i2 =-1. Both i and -i are the square roots of -1
Since a square root has two values, one positive and the other negative
x2 + (6/5)x + (4/5) = 0
has two solutions:
x = -3/5 + √ 11/25 • i
or
x = -3/5 - √ 11/25 • i
Note that √ 11/25 can be written as
√ 11 / √ 25 which is √ 11 / 5

A. 32
B. 18
C. 2
D. 288
Answers
Answer:
A. 32
Step-by-step explanation:
y varies inversely as x
y = k/x
-------------------------
y = 24 when x = 4
find k, the constant of variation
24 = k/4
multiply both sides by 4
96 = k
----------------------------
find y when x = 3
using k = 96
y = 96/3
y = 32

The average number of Saturday night shootings is 5 a night. What’s the chance that there will be a need for exactly 3 shootings this Saturday?
Answers
Answer:
0.14
Step-by-step explanation:
Using the poisson probability relation :
P(x = x) = (λ^x * e^-λ) ÷ x!
From the question ; mean, λ = 5 ; x = 3
Hence,
P(x = 3) = (5^3 * e^-5) ÷ 3!
P(x = 3) = (125 * 0.0067379) / 6
P(x = 3) = 0.8422375 / 6
P(x = 3) = 0.140

(1) 1 and the integer itself.
[tex]1 * 858 = 858[/tex]
(2) 1 prime factor and the product of other primer factors
[tex]2 * 429 = 858[/tex]
[tex]3 * 286 = 858[/tex]
[tex]11 * 78 = 858[/tex]
[tex]13 * 66 = 858[/tex]
(3) A pair of prime factors and the product of remaining primer factors
[tex]6 * 143 = 858[/tex]
[tex]22 * 39 = 858[/tex]
[tex]26*33 = 858[/tex]
Hence, the list are:
