I need help, does anyone know how to simplify radical expressions?
Answer:
[tex]-2a\sqrt[3]{4a^2}[/tex]
Step-by-step explanation:
[tex]\sqrt[3]{-32a^5}\\\\=\sqrt[3]{-(2^5)a^5}\\\\=\sqrt[3]{(-1)^3(2^5)(a^5)}\\\\=\sqrt[3]{(-1)^3(2)^3(a)^3*2^2a^2}\\\\=-1*2*a*\sqrt[3]{4a^2}\\\\=-2a\sqrt[3]{4a^2}[/tex]
Answer:
[tex]-2a\sqrt[3]{4a^{2} } \\[/tex]
Step-by-step explanation:
1) First, let's break down [tex]-32a^5[/tex] into its smallest factors:
[tex](-2) (-2) (-2) (-2) (-2) (a) (a) (a) (a) (a)[/tex]
2) The 3 next to the radical indicates how many of the same kind of factors we need to group together in order to take that certain number or variable "out" of the radical. (It's a bit easier to understand if you look into the work shown below.) In this case, we need to group together the same kind of factors in groups of 3.
So, looking at the our factors, we can take out at least one group of (-2)s and one group of (a)s. Let's take them out of the radical like so:
[tex](-2) (a) \sqrt[3]{(-2)(-2)(a)(a) }[/tex]
3) From here, all you need to do is simplify and multiply back together:
[tex]-2a\sqrt[3]{4a^2}[/tex]
This was a very short explanation, so if you have any questions on how to solve these kinds of problems, please do not hesitate to ask!
if the lengths of two sides of a triangle are 24 and 18, what is the largest possible integer length of the third side of the triangle?
Answer:
[tex]41\ units[/tex]
Step-by-step explanation:
[tex]As\ we\ know\ that,\\The\ sum\ of\ two\ sides\ of\ a\ triangle\ will\ always\ be\ greater\ than\ the\ Third\ Side.\\Hence,\\As\ we\ are\ given,\\Length\ of\ Side\ 1=24\ units\\Length\ of\ Side\ 2=18\ units\\Hence,\\The\ Length\ of\ Side\ 3<(24+18)\\Or,\\The\ Length\ of\ Side\ 3<42\\Now,\\As\ the\ length\ of\ third\ side\ cannot\ be\ equal\ to\ the\ sum\ of\ the\ other\ two sides.\\Hence,\\The\ Length\ of\ Side\ 3\neq 42\\As\ we\ are\ told\ to\ find\ the\ integer\ value,\\[/tex]
[tex]The\ nearest\ integer\ lesser\ than\ 42\ is\ 42-1\ or\ 41.\\Hence,\\The\ largest\ possible\ integer\ length\ of\ the\ third\ side\ of\ the\ triangle=41\ units[/tex]
Answer:
41

The 17 students on the math team want to raise $483.62 to buy practice books they have already raised $218.25 of each students raises the same amount how much more money must each student raise
Answer:
Each stuydent must raise $15.61 to reach their goal.
Step-by-step explanation:
Their goal is 483.62, but they already have 218.25 so we subtract,
483.62 - 218.25 = 265.37
Since there are 17 students and they raise the same amount we need to divide by the amount of students to find out how much money each of them need to raise to add up to their goal.
265.37/17 = $15.61
At an amusement park, Bill enjoys two rides on the water slide and three rides on the Ferris wheel, and it cost him $15.55. If the water slide costs $3.95, find the cost of the Ferris wheel.
Answer:
$2.55
Step-by-step explanation:
Let
Cost of Water slide = x
Cost of Ferris wheel = y
Cost of Water slide = $3.95
Cost of Ferris wheel = ?
Total cost = $15.55
The equation
2x + 3y = 15.55
2(3.95) + 3y = 15.55
7.9 + 3y = 15.55
3y = 15.55 - 7.9
3y = 7.65
y = 7.65 / 3
= 2.55
y = $2.55
The cost of the Ferris wheel is $2.55
What is the value of f(-5), if f(x) = -9x -4 ?
[tex]f( - 5) = - 9( - 5) - 4 \\ f( - 5) = 45 - 4 = 41[/tex]
Therefore the answer is 41
Answer:
Step-by-step explanation:
f(-5) = (-9 * -5) -4
f(-5) = 45 - 4
f(-5) = 41

What is its length? Enter the correct answer. The perimeter of a rectangle is twice the sum of its length and its width. The perimeter is 34 meters and its length is 2 meters more than twice its width. 000 Clear all
Answer:
Width = 5 meters
Length = 12 meters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Perimeter = 34 meters
Width = x meters
Length = 2x + 2 meters
Perimeter of a rectangle = 2(length + width)
34 = 2{(2x+2) + x}
34 = 2(2x + 2 + x)
34 = 2(3x + 2)
34 = 6x + 4
34 - 4 = 6x
30 = 6x
x = 30 / 6
x = 5 meters
Width = x meters = 5 meters
Length = 2x + 2 meters
= 2(5) + 2
= 10 + 2
= 12 meters

Hope this helps. Pls give brainliest.
sorry if its blury
it says sketch the graph of each line
{y=-x+1
{y=4x-14
please help me
my paper is due today
[tex] - x + 1 = 4x - 14 \\ - x - 4x = - 14 - 1 \\ - 5x = - 15 \\ x = 3[/tex]
Substitute x = 3 in any given equations. I will do in y = - x + 1
[tex]y = - x + 1 \\ y = - 3 + 1 \\ y = - 2[/tex]
Therefore the answer is (3,-2)

find the length of MN.
Answer:
32
Step-by-step explanation:
39 = 4(x + 5) + 2x + 1
39 = 4x + 20 + 2x + 1
39 = 6x + 21
18 = 6x
x = 3
MN = 4(x + 5)
MN = 4(3 + 5)
MN = 4(8)
MN = 32
hope this helped!
Step-by-step explanation:
MP = MN + NP
39 = 4(x+5) + 2x+1
39 = 4x + 20 + 2x + 1
39 = 6x + 21
6x = 39-21
6x = 18
x = 3
Then,
MN = 4(3+5)
= 4×8
= 32

Twelve times a number r plus half a number s equals seventeen. Twice the number r plus
one-twelfth of the number s equals seven. What are the two numbers?
Given:
Twelve times a number r plus half a number s equals seventeen.
Twice the number r plus one-twelfth of the number s equals seven.
To find:
The two numbers.
Solution:
Twelve times a number r plus half a number s equals seventeen. So,
[tex]12r+\dfrac{1}{2}s=17[/tex] ...(i)
Twice the number r plus one-twelfth of the number s equals seven.
[tex]2r+\dfrac{1}{12}s=7[/tex] ...(ii)
Multiply both sides by 2 in (i).
[tex]24r+s=34[/tex] ...(iii)
Multiply both sides by 12 in (ii).
[tex]24r+s=84[/tex] ...(iv)
Using (iii) and (iv), we get
[tex]43=84[/tex], which is a false statement because [tex]43\neq 84[/tex].
It means, equation (i) and (ii) has not solutions.
Therefore, the two numbers for the given problem does not exist.

1/2m−5=23. What is the answer please tell me, it's very important.
Answer:
m = 56
Step-by-step explanation:
1/2m - 5 = 23
add 5 to both sides
1/2m - 5 + 5 = 23 + 5
1/2m = 28
multiply both sides by 2
1/2m(2) = 28(2)
m = 56

A frog jumps ( 3/5 feet in the span of 2 2/3 seconds. Find the unit rate, in feet per second, that the frog is moving at. Express any improper fractions as mixed numbers.
Answer: [tex]4\dfrac{4}{9}\text{ feet per second}[/tex]
Step-by-step explanation:
Given: A frog jumps [tex]\dfrac35[/tex] feet in the span of [tex]2\dfrac23[/tex] seconds.
So, distance = [tex]\dfrac35[/tex] feet , time = [tex]2\dfrac23[/tex] seconds = [tex]\dfrac83[/tex] seconds.
Unit rate of movement = [tex]\dfrac{\dfrac83}{\dfrac35}\text{ feet per second}[/tex]
[tex]=\dfrac{40}{9}\text{ feet per second}\\\\=4\dfrac{4}{9}\text{ feet per second}[/tex]
Unit rate= [tex]4\dfrac{4}{9}\text{ feet per second}[/tex]
