A. IMA = 32/10 = 3.2

harkovskaia [24]3 years ago

we would solve this by using the equation: LMA=L/H

now, we have to plug in the numbers LMA= 32/10

LMA= 3.2

so, the answer is 3.2

The diagram below , not drawn to scale , shows three points R , S and F on the horizontal

Katyanochek1 [597]

The question is an illustration of right-angled triangles.

The length of RF is 49.1 m
The length of SR is 65.5 m
The elevation from S to T is 30 degrees

See attachment for the sketch

(a) Show that RF = 49.1

Considering $\triangle FTR$

We have:

$\tan(R) = \frac{FT}{RF}$ ---- tangent ratio

This gives:

$\tan(27) = \frac{25}{RF}$

Make RF the subject

$RF = \frac{25}{\tan(27)}$

$RF = 49.06$

Approximate

$RF = 49.1$

(b) Calculate SR

Considering $\triangle FRS$

We have:

$SR^2 = RF^2 + FS^2$ ---- Pythagoras theorem

This gives

$SR^2 = 49.1^2 + 43.3^2$

$SR^2 = 4285.7$

Take square roots

$SR = 65.5$

(c) The elevation from S to T

To do this, we make use of tangent ratio from $\triangle FST$

$\tan(S) = \frac{FT}{FS}$

$\tan(S) = \frac{25}{43.3}$

Take arc tan of both sides

$S = \tan^{-1}(\frac{25}{43.3})$

$S = 30^o$

An object is dropped from the top of Pittsburgh's USX Towers, which is 841 feet tall. The

dlinn [17]

Answer:

Step-by-step explanation:

h(t) = 841 - 16t

[Is this written correctly? The time is usually t^2, not t. I'll solve with the written equation, but check the equation]

The height at ground level is 0, so we want the value of t when h(t) = 0:

0 = 841 - 16t

-16t = -841

t = 53 seconds

One can also graph this formula and find the time to hit the ground at the point the line intersects the x axis (x = 0).

====

If the equation should have read h(t) = 841 - 16t^2, solve it as above, setting h(t) = 0.

t = (29/4) seconds

This can also be graphed.
