Yes you can do and this :
\(\frac{a^4}{3(3^2-a^2)}\)
Is that completely simplified?
\(\frac{\frac{a^2}{3^2}}{\frac{3^2-a^2}{3a^2}}=\frac{3a^2a^2}{3^23^2-3^2a^2}=\frac{a^4}{3^3-3a^2}\)
THANKS! That cleara it up! Just basic algebraic manipulation.
Yes tan= 15/8 it's between 61,62 degrees!
15/8 = 1.875
to find the ANGLE arctan (1.875) arctan is tangent inverse...= 61.92 degrees
First, let y = log3(x). Then:
y2 - 3y - 10 = 0
This factors as: (y - 5)(y + 2) = 0
So y = 5 and y = -2 are solutions for y.
So, we have 5 = log3(x), which means x = 35
Also -2 = log3(x), which means x = 3-2
Again , a right triangle
TANGET = opposite / adjacent opp = 35 adj =50
tan = 35/50
Arctan (35/50) = 35 degrees
Glad you're on-board! Hope you learn a lot.....
Welcome!
Sin of right triangle = opposite / hypotenuse
You need to find the hypotenuse of this triangle
sin 65 = 15/hyp
re-arrange
hyp = 15 /sin 65 = ~16.6 ft
\(sin(x)=\frac{opposite }{hypotenuse }<=> sin(65)= \frac{15 ft}{d} <=> d= \frac{15}{0,906}\)
d~16,556 ft
Hope this helps!
\(\frac{banana tree}{mangotree}=\frac{2}{3} <=> \frac{2.5}{mangotree}=\frac{2}{3} <=> mangotree=\frac{2.5\times3}{2}=\frac{7.5}{2}=3.75m\)
So mango tree is 3.7m tall!

Hi there.

A and B are independent events because P(A|B)=P(A) and P(B|A)=P(B)
is correct
The average age of a football player in a league is 27.
The age of 12 football players in the league are
25, 23, 26, 29, 37, 23, 32, 29, 25, 22, 31, and 34.
Enter the sample mean and the population mean.
x¯x¯ = years

The fixed costs are spread across the number of scissors produced....
the other cost is per unit
so EACH scissor costs ( M(s) + L(s) ) /s = 279/s + 1.80
