Answer:
\frac{13+\left(-3\right)^2+4\left(-3\right)+1-\left(-10-\left(-6\right)\right)}{\frac{\left(4+5\right)}{\left(4^2-3^2\left(4-3\right)-8\right)}+12}=5
Step-by-step explanation:
Answer:
The correct option is C.
C) -x + 2
Step-by-step explanation:
In mathematics, the term which is being divided is called a dividend. The term by which the dividend is getting divided is called a divisor. The quotient is the term we get after dividing the dividend by a divisor.
Here in this case, the dividend is written.
-x² x x
which in the equation form is written as
-x² + x + x
add the x terms to simplify
-x² + 2x
The divisor is given as x, divide the equation by x:
(-x² + 2x)/x
(-x²/x) + (2x/x)
-x+2
Which is the quotient.
Answer: 
Step-by-step explanation:
The circular oil slick is expanding at a rate of 
Let A be the area of the circular oil slick,
So, the changes in A with respect to time (t),
Also, the change in diameter with respect to time(t),
For r = 1.5 m,
![\frac{d}{dt} ( 2 r)]_{r=1.5} = \frac{2}{\pi \times 1.5}=\frac{20}{\pi \times 15}=\frac{4\pi }{3}\text{ meter per hour}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdt%7D%20%28%202%20r%29%5D_%7Br%3D1.5%7D%20%3D%20%5Cfrac%7B2%7D%7B%5Cpi%20%5Ctimes%201.5%7D%3D%5Cfrac%7B20%7D%7B%5Cpi%20%5Ctimes%2015%7D%3D%5Cfrac%7B4%5Cpi%20%7D%7B3%7D%5Ctext%7B%20meter%20per%20hour%7D)
