What equation represents an exponential function that passes through the point (2, 80)?

Mathematics
1 answer:
Marina86 [1]2 years ago

Answer:

f(x) = (4\sqrt{5})^{x}

Step-by-step explanation:

The exponential function looks like the following: f(x) = b^{x}.

If the function passes through the point (2, 80), then:

f(x) = b^{x} → 80 = b^{2}

Solving for 'b':

b = \sqrt{80} →b=4\sqrt{5}

Then, the equation of exponential function that passes through the point (2, 80) is: f(x) = (4\sqrt{5})^{x}

9× 3 1/2=<br> Which choice is the most reasonable answer?
icang [17]

Answer:

31.5 or 63/2

Step-by-step explanation:

to do this, first you need to transform the <u>mixed number</u> <em>(3 1/2)</em> into an <u>improper fraction</u>, to get 7/2.

then you just multiply 9 by 7/2

9/1 (7/2)

63/2 = 31.5

<em>both of the answers in bold are correct</em>

PLEASE HELP ASAP!!!!!!

1. - Since a cube is all the same lengths on all sides you would want to find the area of one of the sides. You would do this by multiplying 3.8 by 3.8.
3.8*3.8=14.44
Since you have six faces on a cube you want to multiply this by 6.
14.44*6=86.64
So your answer for 1. is 86.64 in^2 of glass

3. Same thing as number one. Find the face of one side:
1 1/3*1 1/3 is about 1.7777
Multiply this by the six faces. 
1.7777*6 is about 10.66666
So your answer for 3. is about 10.666 (repeating) in^2

4. For this one, you want to follow the surface area formula for a cylinder. Which is - A=2πrh+2πr^2
When you put all your numbers in it would look like this: 
2*3.14*2*22+2*3.14*2^2
Once you do that equation you will get 301.44
So that should be your answer 301.44 cm^2

Hope this helps!
