Robin is flying a kite. She ties the 50 foot kite string to the ground. If the kite is

krok68 [10]

$\bold{\huge{\orange{\underline{ Solution }}}}$

<h3>Given :-</h3>

We have given in the question that, Robin is flying a kite.
She ties the 50 foot kite string to the ground .
The kite is flying at 40 feet high

We have to find the measure of the angle the string forms with the group that is angle of elevation.

<h3>Let's Begin :-</h3>

According to the given question,

Hypotenuse AC ( Distance of string from the ground) = 50 ft.
Perpendicular height AB ( Distance of the kite from the ground) = 40 ft.

<h3>Therefore, </h3>

By using trigonometric ratios,

{ $\bold{\pink{ Sin Φ = }}{\bold{\pink{\dfrac{Perpendicular}{Hypotenuse }}}}$

$\bold{\red{ Cos Φ = }}{\bold{\red{\dfrac{Base}{Hypotenuse }}}}$

$\bold{\purple{ Sin Φ = }}{\bold{\purple{\dfrac{Perpendicular}{Base }}}}$ }

The Angle of elevation will be 

[ The angle that is formed between the line of sight and base of the triangle is called angle of elevation ]

$\bold{\pink{Sin Φ = }}{\bold{\pink{\dfrac{AB}{AC }}}}$

$\sf{ Sin Φ = }{\sf{\dfrac{40}{50 }}}$

$\sf{ Sin Φ = }{\sf{\dfrac{4}{5}}}$

$\sf{ Sin Φ = 0.8 }$

$\bold{\green{ Φ = 45.83° }}$

Hence, The measure of the angle the string forms with the ground is 45.83° .

Simplify |a+3| + |a−3| , if −3

Rashid [163]

Answer:

Step-by-step explanation:

I'm not sure if you mean whether a = -3, but if you are to plug in -3 for a you should get:

$|-3+3|+|-3-3|\\=|0|+|-6|\\=0+6\\=6$

Marco is studying a type of mold that grows at a fast rate. He created the function f(x) = 345(1.30)x to model the number of mol

Ivahew [28]

1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.

Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:

$345(1.30)^4 = \boxed{985.35}$

Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.
