An arc of length 3 feet is cut off by a central angle of π/4 radians. Find the area of the sector formed

tino4ka555 [31]

so hmm notice the picture below

so $\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{s^2}{2\theta}\qquad
\begin{cases}
\theta=\textit{central angle in radians}\\
s=\textit{length of the arc}
\end{cases}$

I will give brainiest answer to whomever solves this

Nezavi [6.7K]

Let the numbers be x = 5x+18

3(5x+18) + 4x= 16

15x+ 54+ 4x= 16

19x = 16-54

X=-38/19

X= -2

5x+18= 5 × -2+18 = 8

In your own words, explain when a quadratic equation will have no real

Step-by-step explanation:

The equation has no true solution if the discriminant is less than 0.

Please answer this and thank you<br><br> If DE=4x+10, EF=2-1, and DF=9x-15, find DF.

professor190 [17]

I hope that 2-1 means 21.

DE + EF = DF
4x + 10 + 21 = 9x - 15
4x + 31 = 9x - 15
31 = 9x - 4x - 15
31 = 5x - 15
46 = 5x
x = 9 1/5 = 9.2

You want 9x - 15
9*9.2 - 15
82.8 - 15
67.8 <<<<< answer.
If I have given the wrong meaning to 2-1 (which could mean 1) leave another note and I will correct my work.
