I drew it out below (don't you just love my effort? XD)

You're gonna use the sine trig function to find the length of the shadow

sin26 / 1 = 43 / x; now you cross multiply

sin26 x = 43; divide both sides by sin26

x = 43 / sin26

x = 98 which is the shadow

Hope this helps!

What's the difference between an ABSOLUTE extrema and a RELATIVE extrema? ...?
ruslelena [56]
Absolute Extrema<span>. If a function has an </span>absolute<span> maximum at x = b , then f (b) is the largest value that f can attain. Similarly, if a function has an </span>absolute<span> minimum at x = b , then f (b) is the smallest value that f can attain.

</span>The strategy for tracking the sign of the derivative is useful for more than determining where a function is increasing or decreasing. It is also useful for locating the relative extrema of a function. At a relative extrema<span>, a function changes from increasing to decreasing or decreasing to increasing.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

A straw is 25 cm long an 12 mm in diameter.how much liquid can be held in the straw at one time
eduard

Answer:

  • About 28 cm³

Explanation:

The shape of a straw may be modeled by a cylinder; thus, use the formula for the volume of a cylinder with length (or height) 25cm and diameter 12mm.

Formula for the volume of a cylinder:

       V=\pi \times (radius)^2\times height

For the given straw:

  • radius = diameter/2 = 12mm /2 = 6mm

  • Convert to cm: 6mm × 1cm/10mm = 0.6cm

  • height: 25cm

Substitute and compute:

         V=\pi \times (0.6cm)^2\times 25cm\approx28.27cm^2\approx28cm^3

Evaluate inverse functions <br><br> Find the following values f^-1(f(3.14)) <br> F(f(-7))
Margaret [11]

Answer:

1. 3.14

Step-by-step explanation:

If we have

f {}^{ - 1} (f(x)

That just equals

x

For example, consider function

f(x) = 2 {}^{x}

The inverse of that function is

y = 2 {}^{x}

x = 2 {}^{y}

log_{2}(x)  =  log_{2}(2 {}^{y} )

log_{2}(x)  = y

So

f {}^{ - 1} (x) =  log_{2}(x)

If we compose the function, f(x) into f^-1(x).

We get

log_{2}(2 {}^{x})  = x

That proof of that.

1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14

2. We first find f(-7) which is -12,

We then find f(-12)= 5 so the answer here is 5.
