A speeding light camera is situated on a light post above the ground and positioned to aim at the ground at a 30-degree angle. It captures the picture of the back license plate of a car at a 60-degree angle. The car was 10 feet from the light post on which the camera was sitting, and the camera is 20 feet away from the back of the car as shown in the diagram below. Did Benita solve the problem correctly? Explain why or why not.
Did Malcom solve the problem correctly? Explain why or why not.
Did Ramon solve the problem correctly? Explain why or why not.
Benita decided that she wanted to determine the height of the same triangle. Could she use the ratio's from a 30-60-90 triangle to figure out its height? Why or why not?

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

2x^2+5x+17

your welcome. : )

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
