Step-by-step explanation:

Segment drawn to join the two sides of the triangle is parallel to third side of the triangle.

Therefore, by basic proportionality theorem:

$\frac{12}{27} = \frac{6}{x} \\ \\ x = \frac{27 \times 6}{12} \\ \\ \huge \red{ \boxed{x = 13.5 \: units}}$

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.

adoni [48]

Answer: The required derivative is $\dfrac{8x^2+18x+9}{x(2x+3)^2}$

Step-by-step explanation:

Since we have given that

$y=\ln[x(2x+3)^2]$

Differentiating log function w.r.t. x, we get that

$\dfrac{dy}{dx}=\dfrac{1}{[x(2x+3)^2]}\times [x'(2x+3)^2+(2x+3)^2'x]\\\\\dfrac{dy}{dx}=\dfrac{1}{[x(2x+3)^2]}\times [(2x+3)^2+2x(2x+3)]\\\\\dfrac{dy}{dx}=\dfrac{4x^2+9+12x+4x^2+6x}{x(2x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{8x^2+18x+9}{x(2x+3)^2}$

Hence, the required derivative is $\dfrac{8x^2+18x+9}{x(2x+3)^2}$

A hockey player takes 150 shots each week. Sixty percent of these shots go in. How many shots do NOT go in?

Viefleur [7K]

60 percent of 150 is 90. So that means 60 shots do not go in.

A 16 oz bottle of fruit punch costs $2.40. A 24 oz. bottle of fruit punch costs $3.84. Which size costs less per ounce?

mart [117]

The 16 oz bottle costs less. One cent less, to be exact. I came up with this by dividing the total cost (2.40) by the size of the bottle (16). I came up with .15. I did the same with the other cost and size, coming up with .16.
