Answer:

$-\frac{3}{11}\ln(\cot t + \csc t)+C$

Step-by-step explanation:

We are given: $\int \frac{3}{x\sqrt{121-x^2}} dx$

We will use integration by parts.

$x = 11 \sin t\\dx = 11 \cos t \: dt$

$\int \frac{3}{x\sqrt{121-x^2}} dx=\int \frac{3* 11 \cos t \: dt}{11 \sin t\sqrt{121-121\sin^2 t}} =\int \frac{3* 11 \cos t \: dt}{11 \sin t*11\cos t}} =\\\\= \frac{3}{11} \int \csc t = -\frac{3}{11}\ln(\cot t + \csc t)+C$

Ratio of the ages of three children is 2:5:1. The sum of their ages is 32 years. Find the ages of the youngest and the eldest

Hoochie [10]

Answer:the ages of the youngest and the eldest is 4 years and 20 Years respectively

Step-by-step explanation:

Ratio of the ages of three children is 2:5:1.

Total ratio =2+5+1=8

So that

the 1st Child's age =2/8 x 32=8 years

2nd Child's age =5/8 x 32= 20 years

3rd Child's age =1/8 x 32= 4 years

Therefore the ages of the youngest and the eldest is 4 years and 20 Years respectively.

The function f is given by f(x) = 10x + 3 and the function g is given by g(x) = 2×. for each question, show your reasoning

anzhelika [568]

Answer:

i got you :D

Step-by-step explanation:

f(x)= 2x²+4x-6 and g(x)=2x-2, find each function

1. (f/g) (x) = f(x)÷g(x) = (2x²+4x-6)÷(2x-2)

First factor both top and bottom:

(2x-2)(x+3)÷(2x-2) = x+3

2. f(a + 2) = plug (a+2) in anywhere there is an x in f(x)=2x²+4x-6 -->

2(a+2)^2 +4(a+2)-6 = 2(a^2+4a+4)+4a+8-6, now distribute:

2a^2+8a+8+4a+2, combine like terms

2a^2+12a+10

Graph the line that contains the point (-5,-3) and had a slope of -2

Ipatiy [6.2K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: Is the slope

b: Is the cut-off point with the y axis

According to the data of the statement we have to:

$m = -2$

Then, the equation is of the form:

$y = -2x + b$

We substitute the point $(x, y): (- 5, -3)$ and find "b":

$-3 = -2 (-5) + b\\-3 = 10 + b\\-3-10 = b\\b = -13$

Finally, the equation is:

$y = -2x-13$

To graph we place the points $(-5, -3)$ and $(0, -13)$ on the coordinate axis and join the points by a line.

ANswer:

$y = -2x-13$

The graphic is attached.
