Lesson 10: Exponents and Exponential Functions Unit Test
Can ya'll type the answers out so we don't just cross our fingers and pray? There's too much going on in my life to deal with passing my one grade too ahead math class.
Shut up “stop cheating” no one cares abt school policies 😂
Yeah, guys remember if you're doing Connexus for Algebra, the tests are set up to where it will shuffle the answer around. If it's not clear as to what question goes to which in your version, I'd suggest inputting the questions into Mathway to get the answer.

@ranboo ur comment tooooooook me outtt😭😭😭
I need the answers for Algebra 2 unit 2 lesson 10
Radical Functions and Rational Exponents Unit Test
None of these work with my test. I am taking the Unit 2 Lesson 9 Exponents and Exponential Functions Unit Test from Willamette Connections Academy. I need the answers.
bruh I'm stuck I ain't tryna bring down my grade into a B someone please get the answers
Anonymous isnt right, i got 10 outta 24
That's really the only way to know you're not going to fail. Mathway is good for getting the answer and Photomath (It's on ios, not sure about android) is great for finding the steps used to get the final answer. Good luck
I understand people are here to cheat and I get that but why are there some people here to tell us we should not cheat like why are you here if you ain't cheating...smh
Cause all I know is I'm probably failing

yaal aint wanna give the answers for the right test , so it was overdue & i had to guess 😂😂. if yaals is overdue cause yaal looking for the answers for the test that has 1. -(6)^-1 , text me (469) 672-1839. i’ll send the pic of the answers cause im not typing this whole test.
any answers?
I took the test and got a 90%, sorry some of the answers are different for different tests -
1. -(6)^-1 = -1/6
2. (-8.3)^0 = 1
3. -1 / y^-4 = -y^4
4. 4^6 × 4^3 = 4^9
5. (-4)^-6(-4)^7 = -4
6. (t^8)^2 = t^16
7. (5t^3)^-4 = 1/625t^12
8. value of 13x^-3y^-1 for x=-1 and y=4 = -13/4
9. (x^-3)^-5x^6 = x^21
10. (4/7y^5)^2 = 16/49y^10
11. No, the first factor is not a number between 1 and 10
12. 1.4 × 10^-2, 1.4 × 10^-1, 1.5×10^3, 2 × 10^3

I originally got a 80 but I’ll let you have a 100% (just so you don't get confused… when I put A = its not the letter of the answer, it just a shorting for Answer)
-(10)^-1
A = -1/10
(-7.4)^0
A = + 1
-1/y^-4
A = -y^4
4^6 * 4^3
A = 4^9
(-4)^-6(-4)^7
A = -4
(q^9)^2
A = q^18
(6q^6)^-4
A = 1/1,296q^24
What is the value of 13x^-3y^-1 for x = -1 and y = 4?
A = -13/4
(y^-5)^-10y^10
A = y^60
(4/7y^5)^2
A = 16/49y^10
Determine if the number 3.42 * 10^-6 is written in scientific notation. If not, explain.
A = Yes; the number is written is scientific notation.
What is the order of 1.5 * 10^3, 1.4 * 10^1, 2 * 10^3, and 1.4 * 10^-2 from least to greatest.
A = 1.4 * 10^-2, 1.4 * 10^-1, 1.5 * 10^3, 2 * 10^3
Find the simplified form of the expression. Give your answer in scientific notation… (3 * 10^6)(8 * 10^-4)
A = 2.4 * 10^2
(I’m only going to type out the first sentence of the Q)
Astronomers measure large distances in light-years…
A = 1.31 * 10^15
A dino fossil is 93,550,000 years old…
A = 9.355 * 10^7
Radio signals travel at a rate of 3 * 10^8 meters per second…
A = 1.4 * 10^-1
Does the table represent an exponential function?
A = yes
Does the rule y = -5x^6 represent an exponential function?
A = no
Choose the correct graph of the function y = -5(3^x)
A = C (curve is on bottom left)
Choose the correct graph of the function y = ¼(3^x)
A = A (-.- this one is a bit hard to explain… the line is coming on the left on the x-axis and the going to the top right…? sry)
In a appropriate environment, guppies reproduce at an astounding rate…
A = 1, 440 guppies
Ken has decided to raise rabbits but has been warned that the number of rabbits he will have double every month…
A = A (the curve is going up and is pushed out a lot)
A $4, 000, 000 principal earns 5% interest…..
A = $4, 862. 03
A tractor cost 15, 450. 00 and depreciates in value by 14% per year…
A = $9, 827. 07
Ugh that was the longest thing ever xD Feel free to follow me on Fuser… Peace >:3
matter of fact just join my discord my tag is Kusupho#4772 add me to join because i can’t share links
