Answer:
1/4
Step-by-step explanation:
When converting radical expressions to rational exponents the exponent on the radicand (1) becomes the numerator of the rational exponent, and the index/root of the radical (4) becomes the denominator of the rational exponent. (1/4)

What is the percent of change from 100,000 to 20,000?
Step-by-step explanation:
100 % = 100000(1). x % = 20000(2). Therefore, 20000 is 20 % of 100000.
Simplify by using radical. Rationalize denominators.
[tex]2a^{\frac{-1}{-2} }[/tex]
Step-by-step explanation:
First of all, [tex]\frac{-1}{-2}[/tex] is equal to [tex]\frac{1}{2}[/tex] because a negative divided by a negative is positive. So now we've got [tex]2a^\frac{1}{2}[/tex]. Well, a fractional exponent, when simplified, is a root. For example, [tex]x^\frac{1}{3}[/tex] is equal to [tex]\sqrt[3]{x}[/tex], and [tex]x^\frac{2}{5}[/tex] is equal to [tex]\sqrt[5]{x^2}[/tex].
Now this is where people make mistakes. Remember, [tex]2a^\frac{1}{2}[/tex] is really [tex]2*a^\frac{1}{2}[/tex], which means only a is raised to the exponent. We would only raise 2a to the power of [tex]\frac{1}{2}[/tex] if our term was [tex](2a)^\frac{1}{2}[/tex]. But since our term is [tex]2*a^\frac{1}{2}[/tex] we raise a to the power of [tex]\frac{1}{2}[/tex] which is the same as [tex]\sqrt[2]{a}[/tex] or just [tex]\sqrt{a}[/tex]. Then we multiply that result by 2 and we have [tex]2\sqrt{a}[/tex] which is fully simplified.
Which function could produce the graph shown below?
A. f(x) = 4e^ 0.05x
B. Ax) = 4e ^ -0.5x
C. f(x) = 4e^ 0.5x
D. f(x) =4e ^ - 0.05x
Answer: the correct awnser is B. F(x)=4e ^0.5x
Step-by-step explanation: I know because I put it into calculator and found the awnser
The function that could produce the graph will be [tex]\rm y = 4 \ e^{-0.50x}[/tex]. Then the correct option is B.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
[tex]\rm y = a \ e^{bx}\\[/tex]
From the graph, at x = 0, the value of the function is 4. Then we have
[tex]\rm \\4= a \ e^{b\times 0}\\[/tex]
a = 4
Then the exponential equation is given as,
[tex]\rm y = 4e^{bx}[/tex]
From the graph, at x = 1, the value of the function is 2.426. Then we have
[tex]\rm 2.426 = 4 e ^b \\\\e^b = 0.6065[/tex]
Take natural log on both sides, then we have
b lne = ln 0.6065
b = - 0.50
Then the exponential equation is given as,
[tex]\rm y = 4 \ e^{-0.50x}[/tex]
The function that could produce the graph will be [tex]\rm y = 4 \ e^{-0.50x}[/tex]. Then the correct option is B.

what is the rate of change for the numbers 3,5,7,9
Answer:
Plus 2 (+2)
Step-by-step explanation:
The rate of change is always a constant change from the given first term to the next one. In this case, you are adding 2 each time:
3 + 2 = 5
5 + 2 = 7
7 + 2 = 9
etc.
~
Change means difference in the state or condition of a thing and here the thing is number. The change made within them must be following some certain rules or patterns.
They can be uniform and here it is uniform for sure. The terms are increasing by 2 or we can say that for getting th next number, we need to add 2 with the previous.
3 + 2 = 55 + 2 = 77 + 2 = 9So, the rate of change for the above numbers or number series is +2 or addition of 2[tex].[/tex]

Saturday a minor league baseball team gave away baseball cards to each person entering the stadium.On group recieved 28 baseball cards.A second group recieved 84 baseball cards.If each person entering the stadium recieved the same number lf baseball cards, what is the greatest number of baseballs cards they could have recieved?Rewrite using distrubutive property
Answer: 28
Step-by-step explanation:
Given: First group received 28 baseball cards and second group received 84 baseball cards.
Total cards= 28+84 =112
If each person entering the stadium received the same number , the greatest number of baseballs cards they could have received = G.C.D. (28,84,112)
[G.C.D. = greatest common divisor]
Since the prime factorization of 28 , 84 and 112 are as follows
28 = 2 x 2 x7
84 = 2 x 2 x 3 x 7
112 = 2 x 2 x 2 x 2 x 7
G.C.D (28, 84, 112 )= 2 x 2 x7 = 28
The greatest number of baseballs cards they could have received = 28

A. If ΔABC is reflected across the y-axis, what are the resulting coordinates for points A', B', and C'?
B. Sketch the reflection on the coordinate plane.
Answer:
A' = (-1, 6)
B' = (-2, 1).
C' = (-5, 2).
Step-by-step explanation:
Reflection over the y-axis---> (a, b) transforms to (-a, b).
So A (1, 6) ---> A' (-1, 6).
in class 60% are girls and 50 are boys find the total student of class
Hello
60 % are girls
40 % are boys
40 % = 50 boys
60 % = 75 girls
75 + 50 = 125
Step-by-step explanation:
Let number of students be X
Percentage of boys=100-60=40%
No of boys= 40% of X
50= 40×X/100
X= 50 × 100/40
X =125 total number of students

Need help finding the missing side of each triangle?
This is a right triangle. Use the Pythagorean theorem to solve:
x^2 + 5.8^2 = 15.6^2
x^2 + 33.64 = 243.36
Subtract 33.64 from both sides:
x^2 = 209.72
Take the square root of both sides:
x = 14.48171
Round to 1 decimal place:
x = 14.5 in.
Answer:
x = 14.5 in
Step-by-step explanation:
There is something called pythagoras' theorem. It states that
a^2 + b^2 = c^2,
a, b and c being sides of a right-angled triangle.
C is always the hypotenuse and a and b are any of the other two.
(The hypotenuse is always the longest side, and always opposite to the right angle, which is always the biggest angle of a right-angled triangle.)
So here we know two sides, the hypotenuse and another side. Let's substitute them into the formula:
5.8^2 + x^2 = 15.6^2
x^2 = 15.6^2 - 5.8^2
x^2 = 243.36 - 33.64
x^2 = 209.72
x = sqr209.72
x = 7sqr107/5 = 14.48171261 in
= 14.5 in (if rounded to 3 significant figures)
You could use a shortcut to do all this and find the answer more quickly:
a^2 = c^2 - b^2 or b^2 = c^2 - a^2
also:
a = sqr(c^2 - b^2)
x = Sqr(15.6^2 - 5.8^2)
= 14.5 in
please help, i need to do this by today but i cant figure it out.
How would you calculate ( 2x + 1 )( x + 6 )( x - 4 ) = 2x^3 + ax^2 + bx -24
(2x+1)(x+6)(x-4)= 2x³+ax²+bx-24
(2x²+x+12x+6)(x-4) = 2x³+ax²+bx-24
2x³+x²+12x²+6x-8x²-4x-48x-24 = 2x³+ax²+bx-24
2x³+x²+12x²+6x-8x²-4x-48x-24- 2x³-ax²+bx-24=0
5x²-46x-ax²+bx-48=0
-ax²+5x²+bx-46x-48=0
