Which is a third degree polynomial with -3 and 2 as its only zeros?a. f(x)=x^3+x^2-8x-12
b. f(x)=x^3+2x^2-5x-6
c. f(x)=x^3+4x^2-3x-18
d. f(x)=x^2+x-6

Answers

Answer 1
Answer:

Answer:b

Step-by-step explanation:

f(x)=x^3+2x^2-5x-6

Put x= -3 in the equation

f(-3)=-3^3+2*3^2-5*3-6

= -27+18+15-6= 0

f(2)= 2^3+2*2^2-5*2-6

=8+8-10-6= 0

Looking north, two skyscrapers are sighted from the viewing deck of the Empire State Building at 1250 feet up. One skyscraper is sighted at a 20° angle of depression and a second skyscraper is sighted at a 30° angle of depression. How far apart are the two skyscrapers to the nearest foot?

Answers

The angle of depression is the angle between the line of sight and a vertical line.

The distance between the two skyscrapers is 1269ft

I've added as an attachment, a figure that illustrates the scenario

First, we calculate distance AB using the following tangent ratio

\mathbf{\tan(\theta) = (Opposite)/(Adjacent)}

So, we have:

\mathbf{\tan(60) = (AB)/(1250)}

Make AB the subject

\mathbf{AB = 1250 * \tan(60)}

Next, we calculate distance AC using the following tangent ratio

\mathbf{\tan(\theta) = (Opposite)/(Adjacent)}

So, we have:

\mathbf{\tan(60+10) = (AB + BC)/(1250)}

\mathbf{\tan(70) = (AB + BC)/(1250)}

Make AB + BC, the subject

\mathbf{AB + BC = 1250 * \tan(70)}

Make BC the subject

\mathbf{BC = 1250 * \tan(70) - AB}

Substitute \mathbf{AB = 1250 * \tan(60)}

\mathbf{BC = 1250 * \tan(70) - 1250 * \tan(60)}

\mathbf{BC = 1269}

Hence, the distance between the two skyscrapers is 1269ft

The sum of two consecutive integers is 183. What is the smaller integer?

Answers

91

Explanation: Since the ones digit ends in a 3, that means the the ones digits of the two consecutive integers must be 1 and 2 or 6 and 7. However, you see 18 in the number 183. 9 + 9 = 18. When you add 6 and 7, you have to carry over one. However, when you add 1 and 2, you do not. Therefore, the two consecutive numbers are 91 and 92. 91 is the smaller integer, so that is the answer.

Answer:

yes the answer is 91

you pay 3.3 cents per minute for long-distance phone calls on your phone. your phone bill is $3.40 write and solve an equation to find the number of minutes m of long-distance calls you made

Answers

If you would like to know the number of minutes of long-distance calls you made, you can calculate this using the following steps:

3.3 cents = $0.033
m = $3.40 / 3.3 cents
m = $3.40 / $0.033 = 3.40 / 0.033
m = 103.03 minutes 

The correct result would be 103.03 minutes.
