Find the area and the circumference of a circle with diameter 9 yards using the value 3.14 for pi

Mathematics

Ray Of Light [21]3 years ago

Area of circle = pi r^, (r)radius is half the diameter so 9÷2=4.5 so in this scenario it would be 3.14×4.5^
3.14×4.5×4.5=63.6

circumference of circle= diameter×pi (3.14)
so 9×3.14=28.3

3^x+2=8^x-1 Solve for x.
zubka84 [21]

I assume the equation is supposed to be

3^{x+2}=8^{x-1}

Then we can write

9\cdot3^x=\dfrac18\cdot8^x\implies\left(\dfrac38\right)^x=\dfrac1{72}

Take the logarithm of base 3/8 on both sides:

\log_{3/8}\left(\dfrac38\right)^x=\log_{3/8}\dfrac1{72}

\implies x\log_{3/8}\dfrac38=-\log_{3/8}72

\implies x=-\log_{3/8}72

- - -

If the equation is actually 3^x+2=8^x-1, I'm afraid it cannot be solved exactly.

Please help guys ♡♡♡♡♡♡​

Answer:

I'm pretty sure the Y position of the eyes is 70.

If the Variable Y is equal to 70, and the Y variable is where the Y axis value goes. Then the Y position of the eyes is equal to the Y variable which is 70. I think that makes sense, but feel free to comment if it does not so that I can help you figure it out.

-(-4)(-6)-3/5(10+15)/1/3
Ksenya-84 [330]

Answer:

-29

solving steps:

\sf \hookrightarrow -\left(-4\right)\left(-6\right)-3/5\left(10+15\right)/1/3

\sf \hookrightarrow  -\left(-4\right)\left(-6\right)-3/5\cdot \:25/1/3

\sf \hookrightarrow  -24-3/5\cdot \:25/1/3

\sf \hookrightarrow  -24-5

\sf \hookrightarrow  -29
