Implify the expression –3(x + 3)2 – 3 + 3x. What is the simplified expression in standard form?

1 answer:

5 0

–3(x + 3)^2 – 3 + 3x
First, we expand the term to be squared:(x + 3)^2 = x^2 + 6x + 9So the expression becomes-3(x^2 + 6x + 9) - 3 + 3x-3x^2 - 18x - 27 - 3 + 3x-3x^2 - 15x - 30

A climber is standing at the top of Mount Kilimanjaro, approximately 3.7 mi above sea level. The radius of the Earth is 3959 mi.

RoseWind [281]

We are given
height = 3.7 mi
radius = 3959 mi

We are asked for the distance between the man and the horizon
The straight line from the man to the horizon is a tangent line to the surface of the earth
Using Pythagorean theorem
(3.7 + 3959)² = 3959² + d²

Solve for d
d = 171 mi

Calculate the unit rate: write your answer as a decimal 1/2 mile in ever 1/3 hour

Alexandra [31]

Answer:

$unit \: rate = \frac{distance}{time}$

unit rate is similar to speed / velocity:

$unit \: rate = \frac{ (\frac{1}{2} )}{ (\frac{1}{3})} \\ \\ = \frac{1}{2} \div \frac{1}{3} \\ \\ = \frac{1}{2} \times \frac{3}{1} \\ \\ = > { \boxed{ \boxed{unit \: rate = \frac{3}{2} \: miles \: per \: hour}}}$

[unit rate must have units including per <time> ]
