marshall27 [118]

Answer:

Step-by-step explanation:

So let's think about what values you can take square root of...

anything but negative values!

So the first one is not correct because you can also take square root of 0,

squareroot of 0 is 0.

So because of this, C and D are both correct, E is correct because root  x is an increasing function. B is incorrect because (0,0) is an intercept.

Simplify <br>99=2(-7b-3)+7​
Arisa [49]

Answer:

b=-7

Step-by-step explanation:

Simplifying

99 = 2(-7b + -3) + 7

Reorder the terms:

99 = 2(-3 + -7b) + 7

99 = (-3 * 2 + -7b * 2) + 7

99 = (-6 + -14b) + 7

Reorder the terms:

99 = -6 + 7 + -14b

Combine like terms: -6 + 7 = 1

99 = 1 + -14b

Solving

99 = 1 + -14b

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '14b' to each side of the equation.

99 + 14b = 1 + -14b + 14b

Combine like terms: -14b + 14b = 0

99 + 14b = 1 + 0

99 + 14b = 1

Add '-99' to each side of the equation.

99 + -99 + 14b = 1 + -99

Combine like terms: 99 + -99 = 0

0 + 14b = 1 + -99

14b = 1 + -99

Combine like terms: 1 + -99 = -98

14b = -98

Divide each side by '14'.

b = -7

Simplifying

b = -7

A helicopter is hovering 450 feet above the ground. The angle of elevation
SIZIF [17.4K]

Answer:

The distance of helicopter from the injured person is 542.82 feet  

Step-by-step explanation:

Given as :

The height of the hovering helicopter above the ground = h = 450 feet

The angle of elevation from injured person to helicopter = Ф = 56°

Or, Let the distance of of helicopter from person = x feet

Now, From Triangle

∵ Sin Ф = \dfrac{\textrm Perendicular}{\textrm Hypotenuse}

∴  Sin 56° = \dfrac{\textrm h}{\textrm x}

Or, 0.8290 = \dfrac{\textrm 450}{\textrm x}

Or , x = \dfrac{\textrm 450}{\textrm 0.8290}

I.e x = 542.82 feet

So, The distance from injured person to helicopter = 542.82 feet

Hence The distance of helicopter from the injured person is 542.82 feet  Answer
