An imaginary number is a number that, when squared, has a negative result. The imaginary number is given by √-1. It is denoted by i.
The simplest radical form of 3√-50 is 3√50i.
What is an imaginary number?An imaginary number is a number that, when squared, has a negative result. The imaginary number is given by √-1. It is denoted by i.
We have,
3√-50
We can separate √-50 = √-1 x √50
We can write as:
= 3 x √-1 x √50
= 3√50 i
This is the simplest radical form of 3√-50.
Thus the simplest radical form of 3√-50 is 3√50i.

Use the function f(x)= - 4^x-1 - 2 to answer the questions below.
1.) State the equation for the asymptote.
2.)What is the range?
3.)What is the domain?
4.) Finally which axis is f(x) reflected over and what caused the reflection?
Answer:
See below for answers and explanations
Step-by-step explanation:
I assume the function you wrote was [tex]f(x)=-4^{x-1}-2[/tex]
1) The equation for the horizontal asymptote is y=-2 since a function of the form f(x) = a(b^x) + c always has a horizontal asymptote at y = c, so c=-2, therefore the horizontal asymptote equation is y=-2
2) The range is (-∞,-2) since any real value of y that is less than -2 but doesn't equal -2 (since it's not included) will be a solution.
3) The domain is (-∞,∞) since any real value of x will be a solution.
4) The axis that f(x) is reflected over is the x-axis because when you negate a base in an exponential function, that will occur.

Need help with this problem:
Natalie is buying cat food to store in a bin that holds 30 cups of dry cat food. The store has bags of cat food that comes in different sizes. A small bag of food contains 8 1/4 cups of food. A medium bag holds 12 3/4 cups of food. A large bag holds 20 7/8 cups of food. Natalie buys multiply bags of the same size. Without calculating the exact amount determine how many bags Natalie should buy to get close to filling the bin as she can without going over 30 cups of food.
9514 1404 393
Answer:
2 medium bags
Step-by-step explanation:
Using estimates of 8, 12, and 20 for the number of cups in each bag size, you can see that the number of each size needed is ...
floor(30/8) = 3 . . . small bags
floor(30/12) = 2 . . . medium bags
floor(30/20) = 1 . . . large bag
3 small bags will contain 3(8 1/4) = 24 3/4 cups.
2 medium bags will contain 2(12 3/4) = 24 3/2 = 25 1/4 cups
1 large bag will contain 20 7/8 cups.
The closest Natalie can get without exceeding the container size is with purchase of 2 medium bags.
_____
Additional comment
The best solution would be to purchase 1 small and 1 large bag, for a total of ...
8 1/4 +20 7/8 = 28 9/8 = 29 1/8 . . . cups
However, that purchase is not multiple bags of the same size.

The radius of a right circular cone is increasing at a rate of 1.4 in/s while its height is decreasing at a rate of 2.1 in/s. At what rate is the volume of the cone changing when the radius is 120 in. and the height is 175 in.
Given:
[tex]\dfrac{dr}{dt}=1.4\text{ in/s}[/tex]
[tex]\dfrac{dh}{dt}=-2.1\text{ in/s}[/tex]
To find:
The rate of change in volume at [tex]r=120\text{ in. and }175\text{ in.}[/tex]
Solution:
We know that, volume of a cone is
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Differentiate with respect to t.
[tex]\dfrac{dV}{dt}=\dfrac{1}{3}\pi\times \left[(r^2\dfrac{dh}{dt}) + h(2r\dfrac{dr}{dt})\right][/tex]
Substitute the given values.
[tex]\dfrac{dV}{dt}=\dfrac{1}{3}\times \dfrac{22}{7}\times \left[(120)^2(-2.1) +175(2)(120)(1.4)\right][/tex]
[tex]\dfrac{dV}{dt}=\dfrac{22}{21}\times \left[-30240+58800\right][/tex]
[tex]\dfrac{dV}{dt}=\dfrac{22}{21}\times 28560[/tex]
[tex]\dfrac{dV}{dt}=29920[/tex]
Therefore, the volume of decreased by 29920 cubic inches per second.

Answer:
[tex] m\angle 1 = 115\degree \\\\
m\angle 2= 130\degree \\\\
m\angle 6= 60\degree \\\\[/tex]
Step-by-step explanation:
[tex] m\angle 1 = m \angle 5\\(corresponding \: \angle s) \\\\
\because m\angle 5 = 115\degree \\
\therefore m\angle 1 = 115\degree \\\\
m\angle 2 = m \angle 7\\(exterior \: alternate \: \angle s) \\\\
\because m\angle 7 = 130\degree \\
\therefore m\angle 2= 130\degree \\\\
m\angle 4 + m\angle 5= 180\degree\\\\
6y\degree + (13y - 10)\degree = 180\degree\\\\
(19y - 10)\degree = 180\degree\\\\
19y - 10 = 180\\\\
19y = 180+ 10\\\\
19y = 190\\\\
y = \frac{190}{19}\\\\
y = 10\\\\
m \angle 4 = 6y\degree \\\\
m \angle 4 = 6\times 10\degree \\\\
m \angle 4 = 60\degree \\\\
\because m\angle 6 = m \angle 4\\( alternate \: \angle s) \\\\
\therefore m\angle 6= 60\degree \\\\[/tex]

$24 shirt; 6% tax what is the answer please
The tax amount on shirt whose Selling Price is $24 at a tax rate of 6% is $1.44.
What is Tax?
A tax is a financial charge imposed on a taxpayer by a governmental organization in order to fund government spending and public expenditures.
Given is the selling price of shirt as $24. The tax rate is 6%.
Selling price of shirt [S.P.] = $24
Tax rate [R%] = 6%
Therefore, the tax amount = T[A] will be -
T[A] = $(S.P x R/100)
T[A] = $(24 x 6/100)
T[A] = $(24 X 0.06)
T[A] = $1.44
Therefore, the tax amount on shirt whose Selling Price is $24 at a tax rate of 6% is $1.44.
