Answer:
C
Step-by-step explanation:
They are written in (x,y) coordinates. so (0,2 1/2) is the dot on the y axis located at 2 1/2 and is directly on the line as x is 0 and y is 2 1/2.
(-1/2,0) coordinate will be on the left of the origin (the centre of the graph a.k.a 0,0) as the x is negative. the y is 0 so it will be on the x axis.
Just remember, if x is negative then the dot moves to the left, if it is positive then to the right. If y is positive then it will move upwards. If it is negative then it will move downwards. Therefore, the x coordinate controls right and left, the y coordinate controls up and down. If it is 0 then it will not move and just stay on that axis.
A cone is placed inside a cylinder. The cone has half the radius of the cylinder, but the height of each figure is the same. The cone is tilted at an angle so its peak touches the edge of the cylinder’s base. What is the volume of the space remaining in the cylinder after the cone is placed inside it?
Answer:
[tex]\frac{11}{12}\pi r^{2}h\ units^{3}[/tex]
Step-by-step explanation:
we know that
Te volume of the cone is equal to
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
we have
[tex]r=(r/2)\ units[/tex]
substitute
[tex]V=\frac{1}{3}\pi (r/2)^{2}h[/tex]
[tex]V=\frac{1}{12}\pi r^{2}h[/tex]
Te volume of the cylinder is equal to
[tex]V=\pi r^{2}h[/tex]
we know that
To find the volume of the space remaining in the cylinder after the cone is placed inside it, subtract the volume of the cone from the volume of cylinder
so
[tex]\pi r^{2}h-\frac{1}{12}\pi r^{2}h=\frac{11}{12}\pi r^{2}h\ units^{3}[/tex]
Find the missing terms in the equation so that it is true. (3x + ?)^2=9x^2 + ?? +49y^2
Answer:
see explanation
Step-by-step explanation:
Note that 9x² and 49y² are perfect squares.
9x² = (3x)² → 3x is the first term
49y² = (7y)² → 7y is the second term
Hence
(3x + 7y)² = 9x² + 42xy + 49y²

The Value of x in terms of b is ______
The Value of x when b is 3 is _______
Answer:
x = -3/b
x = -1
Step-by-step explanation:
-2(bx-5)=16
Divide each side by -2
-2(bx-5)/-2=16/-2
bx-5 = -8
Add 5 to each side
bx-5+5 = -8+5
bx = -3
Divide each side by b
bx/b = -3/b
x = -3/b
If b = 3
x = -3/3
x = -1
Answer:
-3/b; -1
Step-by-step explanation:
A. Solve the equation

Given that the total size of the file is 234 MB and only [tex]\frac{19.3}{100}[/tex] has been downloaded,
number of MB downloaded,
= [tex]\frac{19.3}{100}[/tex] x 234 MB
= 45.162 MB
= 45.2 MB (rounded off to nearest tenth)
Answer:
45 megabytesStep-by-step explanation:
First, you convert 19.3 to a decimal. That is 0.193. Then, you multiply 0.193 and 234 to get 45.162 megabytes. Since it is asking for the number of megabytes, you will have to round it and get 45 megabytes.

The product is: 2x^3-11x^2+16x-3
Hence, third option is the correct answer ..

The product is 2x³ - 11x² + 16x - 3 ⇒ 3rd answer
Step-by-step explanation:
* Lets explain how to find the product of binomial by trinomial
- If (ax² ± bx ± c) and (dx ± e) are trinomial and binomial, where
a , b , c , d , e are constant, their product is:
# Multiply (ax²) by (dx) ⇒ 1st term in the trinomial and 1st term in the
binomial
# Multiply (ax²) by (e) ⇒ 1st term in the trinomial and 2nd term in
the binomial
# Multiply (bx) by (dx) ⇒ 2nd term the trinomial and 1st term in
the binomial
# Multiply (bx) by (e) ⇒ 2nd term in the trinomial and 2nd term in the binomial
# Multiply (c) by (dx) ⇒ 3rd term in the trinomial and 1st term in
the binomial
# Multiply (c) by (e) ⇒ 3rd term the trinomial and 2nd term in
the binomial
# (ax² ± bx ± c)(dx ± e) = adx³ ± aex² ± bdx² ± bex ± cdx ± ce
- Add the terms aex² and bdx² because they are like terms
- Add the terms bex and cdx because they are like terms
* Now lets solve the problem
∵ The binomial is (x - 3) and the trinomial is (2x² - 5x + 1)
∴ (x)(2x²) = 2x³
∵ (x)(-5x) = -5x²
∵ (x)(1) = x
∵ (-3)(2x²) = -6x²
∵ (-3)(-5x) = 15x
∵ (-3)(1) = -3
∴ (x - 3)(2x² - 5x + 1) = 2x³ + -5x² + x + -6x² + 15x + -3
- Add the like terms
∵ -5x² and -6x² are like term
∴ Their sum is -11x²
∵ x and 15 x are like terms
∴ Their sum = 16x
∴ (x - 3)(2x² - 5x + 1) = 2x³ - 11x² + 16x - 3
* The product is 2x³ - 11x² + 16x - 3

what is (24x-35q) (56q+78x)
Answer:
= 1872x^2 - 1960q^2 - 1386xq
Step-by-step explanation:
First you should distribute.
(24x * 56q), (24x * 78x), (-35q * 56q), (-35q * 78x)
=1344xq + 1872x^2 - 1960q^2 - 2730xq
Now you combine like terms.
= 1872x^2 - 1960q^2 - 1386xq
**NOTE that (^2) means "squared"
Since there are no more like terms that is your final answer. I hope this helps love! :)
find the X-intercept
f(x)=3^(x-1)-2
The answer is:
The function intercepts de x-axis at "x" equal to 1.631.
Why?To find the x-intercept of the function, we need to make f(x) or "y" equal to 0, and then, isolate "x".
So, isolating we have:
[tex]f(x)=3^{(x-1)} -2\\\\0=3^{(x-1)} -2\\\\3^{(x-1)}=2\\\\Log_{3}(3^{(x-1)})=Log_{3}(2)\\\\x-1=0.631\\\\x=0.631+1=1.631[/tex]
Hence, we have that the function intercepts de x-axis at "x" equal to 1.631.

Step-by-step explanation:
We are given that there is chorus of 20 singers and we are to find the number of different trios that can be selected from 20 singers.
This is a problem of combinations where the order of trios is not important.
[tex] C ( 2 0 , 3 ) = \frac { ( 2 0 ! ) } { ( ( 2 0 - 3 ) ! 3 ! ) } [/tex]
[tex]C ( 2 0 , 3 ) = \frac { 2 0 ! } { ( 1 7 ! ) ( 3 ! ) } [/tex]

Find the cube root of 857375 by prime factorization method
Answer:
9
Step-by-step explanation:
3root^857375
Answer:
95
Step-by-step explanation:
The product of the prime factors of 857375 are
5 × 5 × 5 × 19 × 19 × 19 ← express as combination of pairs
= (5 × 19) × (5 × 19) × (5 × 19)

Hence
[tex]\sqrt[3]{857375}[/tex] = [tex]\sqrt[3]{95^{3} }[/tex] = 95
Without using technology, describe the end behavior of f(x) = -3x^4 + 7x^2 - 12x + 13
A. Down on the left, down on the right
B. Down on the left, up on the right
C. Up on the left, down on the right
D. Up on the left, up on the right
Answer:
A. Down on the left, down on the right
Step-by-step explanation:
Let x be negative infinity
f(-∞) = -3 (-∞)^4+ 7(-∞)^2 - 12(-∞) + 13
f(-∞) = -3 (∞)^4+ 7(∞)^2 + 12(∞) + 13
The term that dominates is ∞^4
That term is negative because of the -3, so it goes down
f(∞) = -3 (∞)^4+ 7(∞)^2 - 12(∞) + 13
f(∞) = -3 (∞)^4+ 7(∞)^2 - 12(∞) + 13
The term that dominates is ∞^4
That term is negative because of the -3, so it goes down
It is down at -∞ and down and +∞
The end behavior of the function is determined by the sign of the leading coefficient and the degree of the highest-powered term. Since the leading coefficient for f(x) = -3x^4 + 7x^2 - 12x + 13 is negative and the degree is even, it results in a down on the left, down on the right end behavior.
Explanation:To determine the end behavior of a polynomial function, like f(x) = -3x^4 + 7x^2 - 12x + 13, you look at the coefficient and degree of the highest-powered term. The highest-powered term in the function is -3x^4.
Since the highest degree of the function is even (4), the arms of the graph will go in the same direction. That direction is determined by the sign of the leading coefficient, which is negative in this case. Therefore, the end behavior of f(x) is: Down on the left, down on the right.
So, the correct answer is Option A.
