The radio of the base of two cylindrical tins are r and 3r respectively .if the water level in A is 18cm high , what would be the height of the same quantity of water in B
Answer:
2 cm.
Step-by-step explanation:
Volume of the water is the same in the 2 cyinders,
Volume of water in A = π r^2 * 18.
Volume in B = π (3r)^2 * h.
So 18πr^2 = 9π r^2 h
18 = 9h
h = 18 / 9
= 2

O A. Function fis even.
ОВ.
Function fis neither even nor odd.
O C.
Function fis both even and odd.
D.
Function fis odd.
F(x)= -8x^5+4x^3+5x
Answer:
D) Function f is odd
Step-by-step explanation:
There are three ways to solve this problem:
Method 1
Recall that a function is even if [tex]f(x)=f(-x)[/tex] and odd if [tex]-f(x)=f(-x)[/tex] for all x. Hence, we evaluate [tex]f(-x)[/tex] to check if the function is even, odd, both, or neither:
[tex]f(x)=-8x^5+4x^3+5x\\\\f(-x)=-8(-x)^5+4(-x)^3+5(-x)\\\\f(-x)=8x^5-4x^3-5x[/tex]
Here, we can see that the signs of the original terms switched to their opposite operations, so it is clear that [tex]-f(x)=f(-x)[/tex], which tells us that the function is odd.
Method 2
A function is odd if it has symmetry about the origin, and even if it has symmetry about the y-axis. We can clearly see on the graph there is origin symmetry, so the function is odd.
Method 3
A function is even if every term in that function has an even degree, or odd if every term has an odd degree. We can see that the degrees of each term are odd, so we can conclude that the function is odd.
which number(s) have a 5 that is 10 x the value than the 5 in 13.725?
(a) 5.368
(b) 12.459
(c) 57.31
(d) 6.508
(e) 4.315
(f) 7.65
Answer:
(b) 12.459 and (f) 7.65
Step-by-step explanation:
The value of 5 in 13.725 is 0.005 (or 5 in the thousandths place)
We need to find numbers with 10 times that value in the number.
0.005 x 10 = 0.05 (or 5 in the hundredths place)Evaluating the options given :
(a) 5.368
The value of 5 in this number is 5 in the unit place (No ×)(b) 12.459
The value of 5 in this number is 5 in the hundredths place (Yes √)(c) 57.31
The value of 5 in this number is 5 in the tens place (No ×)(d) 6.508
The value of 5 in this number is 5 in the tenths place (No ×)(e) 4.315
The value of 5 in this number is 5 in the thousandths place (No ×)(f) 7.65
The value of 5 in this number is 5 in the hundredths place (Yes √)Hence, the numbers are : (b) 12.459 and (f) 7.65
Answer:
b and f
Step-by-step explanation:
The 5 in 13.725 is in the thousandth place: 0.005
So three places after the decimal point.
If you multiply 0.005 by 10, then it becomes 0.05 (as multiplying by 10 moves the decimal point one place to the right).
Therefore, we are looking for numbers that have a 5 in the hundredth place, so a 5 in the second place after the decimal point.
There are two numbers that have a 5 in the hundredth place:
(b) 12.459
(f) 7.65

A triangular prism that has a volume of 24 cubic inches is changed by a scale factor of 5. Find the volume of the dilated cube.
A. 120
B. 600
C. 3000
D. 3600
==========================================================
Reason:
If the linear scale factor is 5, then the volume scale factor is 5^3 = 125
Meaning we'll multiply the old volume by 125 to get the new volume
new volume = 125*(old volume)
new volume = 125*(24)
new volume = 3000
---------------
A more in-depth look:
Consider a 2 by 2 by 2 block. Its volume is 2*2*2 = 8
Now multiply each dimension by 5, so we now have a 10 by 10 by 10 block. The new larger volume is 10*10*10 = 1000
The volume ratio is 1000/8 = 125, which matches with the value found earlier.
Since we multiplied each piece by 5, and did so three times, we're really multiplying the volume by 5*5*5 = 125.

This is part of Ivan's homework. A line segment, AB, goes from the point A(4, 7) to the point B(9, 3). AB is translated 3 squares left and 2 squares down. The image of AB is AB. Work out the coordinates of A' and B. Solution A' is at (7, 5). B' is at (12, 1). Ivan has worked out the coordinates of A' and B' incorrectly.
Explain the mistake that he has made.
Ivan mixed up left and right.
He mistakenly added 3 to the x coordinate to shift the points 3 units right, when instead he should have subtracted 3 from the x coordinate to go 3 units left.
Luckily, Ivan correctly shifted the points 2 units down.
The coordinates of A' and B' should be (1,5) and (6,1) respectively.

As the x-values go to positive infinity, the function's values go to positive infinity. The correct option is D.
What is a function?A function is a mathematical formula that describes how the dependent variable and independent variable are related. The dependent variable's value varies in the function together with the independent variable's value.
The correct option is D that as the x-values go to positive infinity, the function's values go to positive infinity.
In mathematics, a function is a rule that gives each input value in a set a distinct output value. A function is, more precisely, a collection of ordered pairs (x, y), where each x-value is matched with precisely one y-value.
The variable x normally represents the input values, also known as the independent variable, while the variable y typically represents the output values, also known as the dependent variable. Typically, a symbol like f(x), where f is the function's name and x is the input variable, is used to represent a function.

Answer:
Step-by-step explanation:
The angles labeled with 2x, 4x, and 3x are on a straight line so their sum is equal to 180
2x + 4x + 3x = 180 add like terms
9x = 180 divide both sides by 9
x = 20
The angle represented with 3x - 30 and the angle represented with 2x + 10 are alternate and their measurement is same
3x - 30 = 2x + 10 export like terms to same side of the equation
3x - 2x = 10 + 30
x = 40
to find the angles replace x with the value found for each.

Find the area of the irregular figure.
4 in.
6 in.
A = [? ]in.²
10 in.
7 in.
11 in.
6 in.
Answer:
160 square inches
Step-by-step explanation:
You can split the irregular figure up into regular shapes:
the top 4x6 inch rectangle
the middle section can be a 18x6 rectangle (added 7+11 for the length)
the bottom 4x7 rectangle (sibtracted 10-6 for the width)
Then, find the area of each section with the equation A = lw.
A= 4(6) = 24 square inches
A = 18(6) = 108 square inches
A = 4(7) = 28 square inches
Add these areas up to get the total area of the irregular figure.
24 + 108 + 28 = 160 square inches

The solution to this equation is p = -6
This expression is related to a First Degree Equation.First degree equation is a mathematical expression and sentence, which is defined by having only one unknown. Its representation is given by: ax+b=0.
— To solve this expression, let's eliminate these square root symbols:
√-5p = √24-p
-5p = 24 - p
— Move the p term before the positive sign equality, thus also shifting the 24th term:
-5p = 24 - p
-5p + p = 24
-4p = 24
— Finally, let's divide the second to the first term of this equation:
-4p = 24
p = 24 ÷ (-4)
p = -6
Therefore, the correct result of this expression will be p = -6

An elementary class consists of 8 boys and 10 girls. A child is chosen at random and it is a girl. A second child is randomly chosen again from the remaining children, and it is a boy. Was the probability of choosing the boy dependent on choosing a girl first
Answer:
Yes
Step-by-step explanation:
So we know the second child was a boy however if the first child was a boy, the probability of getting a second boy would be 7/17 since one boy is missing and one person is missing from the total.
However, if a girl was chosen as the first child, the probability of getting a boy second would be 8/17 since no boys would be missing but one person would be missing from the original total.

Negative Effects of Violent Video Games
In studies conducted by neuroscientists, it was found that teens who regularly play violent video games have lower rates of success in school than teens who do not play violent video games. The same parents who ban violent televisions shows from being watched in their homes must also be careful about the types of video games their teens play. Teens love their games, but their future is at stake.
