1 answer:
Blababa [14]3 years ago
5 0

Answer:

coefficient for k: -2

constant term?: -5

degree of the polynomial: 2

Step-by-step explanation:

The coefficient for k is the number that multiplies k. In this case:

7kn+2k^2-2k-2n-5+5n^2

The constant term is the number that doesn't multiply any variable. In this case:

7kn+2k^2-2k-2n-5+5n^2

The degree of a polynomial is the highest of the degrees of the polynomial's monomials. In this case, the highest monomials are:

7kn+2k^2-2k-2n-5+5n^2

all of them second degree

. A triangle has side lengths of 8, 7, and 14. To the nearest tenth of a degree find the measure of the angle opposite the side
4vir4ik [10]

Given:

The measure of three sides of a triangle are 8, 7 and 14.

To find:

The measure of the angle opposite the side of length 8.

Solution:

According to the Law of Cosine:

\cos A=\dfrac{b^2+c^2-a^2}{2bc}

Let a=8, b=7 and c=14, then by using Law of Cosine, we get

\cos A=\dfrac{7^2+14^2-8^2}{2(7)(14)}

\cos A=\dfrac{49+196-64}{196}

\cos A=\dfrac{181}{196}

Taking cos inverse on both sides.

A=\cos^{-1}\dfrac{181}{196}

A=22.561328

A\approx 22.6

Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.

What is the angle of rotation of the minute hand of a clock moving from 6:10 to 7:00?
igomit [66]
Because the movement of the minute han of a clock is clockwise ↓, then the angle of rotation will be negative.

1) we calculate the number of minutes from 6:10 to 7:00

number of minutes=7:00-6:10=6:60 - 6:10=50 minutes.

2)
We know that:
60 minutes of a clock have turned -360º
Then:

60 minutes of a clock------------------------- -360º
50 minutes of a clock-------------------------      x

x=(50 minutes of a clock * (-360º))/60 minutes of a clock=-300º


Answer:  A. -300º
