3 10 in . = 7 8 mi . what is the unit rate
Sav [38]

Answer: (3/10) in = (7/8) mi

1 in = (7/8) mi ÷ (3/10)

      = 7/8 * (10/3) = 70/24

1 in = (70/24) mi

It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.  

Hope this helps :)

Find the integral of √(x² +4) W.R.T x​
Allushta [10]

Answer:

\frac{x}{2} *\sqrt{x^{2} +4} +\frac{1}{2}*LN(|\frac{x+\sqrt{x^{2} +4} }{2}|) +C

Step-by-step explanation:

we will have to do a trig sub for this

use x=a*tanθ for sqrt(x^2 +a^2) where a=2

x=2tanθ, dx= 2 sec^2 (θ) dθ

this turns \int\limits {\sqrt{x^{2}+4 } } \, dx into integral(sqrt( [2tanθ]^2 +4) * 2sec^2 (θ) )dθ

the sqrt( [2tanθ]^2 +4) will condense into 2sec^2 (θ) after converting tan^2(θ) into sec^2(θ) -1

then it simplifies into integral(4*sec^3 (θ)) dθ

you will need to do integration by parts to work out the integral of sec^3(θ) but it will turn into (1/2)sec(θ)tan(θ) + (1/2) LN(|sec(θ)+tan(θ)|) +C

then you will need to rework your functions of θ back into functions of x

tanθ will resolve back into \frac{x}{2} (see substitutions) while secθ will resolve into \frac{\sqrt{x^{2} +4} }{2}

sec(θ)=\frac{\sqrt{x^{2} +4} }{2}  is from its ratio identity of hyp/adj where the hyp. is \sqrt{x^{2} +4}  and adj is 2 (see tan(θ) ratio)

after resolving back into functions of x, substitute ratios for trig functions:

= \frac{x}{2} *\sqrt{x^{2} +4} + \frac{1}{2}*LN(|\frac{x+\sqrt{x^{2} +4} }{2}|) +C

2.) Find the length of the unknown side. Round your answer to the nearest tenth.
Juli2301 [7.4K]

Answer:

14.1

Step-by-step explanation:

Hey There!

This is a right triangle so we have to use the Pythagorean Theorem to solve for the missing side

given the hypotenuse and a leg we do

hypotenuse^2-given.leg^2

15^2-5^2=?^2\\15^2=225\\5^2=25\\225-25=200\\\sqrt{200} =14.1421356

then we just round to the nearest tenth and get that

?=14.1

Step-by-step explanation:

g*f(x)=g(x+4)=(x+4)³

g*f(-3)=(-3+4)³

= 1³=1
