Hi there!

Like I said earlier that I can't solve #1 so I will only solve #2 and #3
-----------------------------------------------------------------------------------------------

5^x = 7
First, we need to solve for the exponent x
log(5^x) = log(7)
x* (log(5)) = log(7)
x = log7/log(5)
x = 1.209062

---------------------------------------------------------------------------------------

Please let me know when you post the #3

Find the area and the circumference of the circle with the radius 6yd.
fgiga [73]

Answer:

<h2>A = 36π yd² ≈ 113.04 yd²</h2><h2>C = 12π yd ≈ 37.68 yd</h2>

Step-by-step explanation:

The formula of an area of a circle:

A=\pi r^2

The formula of a circumference of a circle:

C=2\pi r

<em>r</em><em> - radius</em>

<em />

We have <em>r = 6yd</em>.

Substitute:

A=\pi(6^2)=36\pi\ yd^2

C=2\pi(6)=12\pi\ yd

If you want round the answers, then use <em>π ≈ 3.14</em>

A\approx(36)(3.14)=113.04\ yd^2

C\approx(12)(3.14)=37.68\ yd

Sketch the graph of each rational function showing all the key features. Verify your graph by graphing the function on
Sonja [21]

Answer:

The graph crosses the x axis at x=0. For x> 0, it rises to a maximum value and then decreases toward y= 0 as x goes to infinity. For x< 0, it decreases to a minimum values then rises toward y= 0 as x goes to negative infinity. y= 0 is a horizontal asymptote but the graph crosses y= 0 at x= 0.

Step-by-step explanation:

A common mistake that students make is to think that a graph cannot cross a slant or horizontal asymptote. This is not the case! A graph CAN cross slant and horizontal asymptotes (sometimes more than once). It's those vertical asymptote critters that a graph cannot cross.

Which of the following can you use to find 20 percent of 48?
11Alexandr11 [23.1K]

Answer:

The answer would be B

Step-by-step explanation:

It would be B as if we do... 20/100 ⨉ 48, our process would be the same as 0.2(48)

=20% of 48

=20/100 ⨉ 48

=0.2 ⨉ 48

=9.6

Hope this helps andmark this as Brainliest if it really helps! Peace Out!!! ✌
