Joaquin recorded a temperature of 62°f this morning for science class. the temperature increased 6 1/2°f in the afternoon before decreasing 8.7°f in the evening. what was the evening temperature?

Step-by-step explanation:

Given : Joaquin recorded a temperature of 62°F this morning for science class.

The temperature increased in the afternoon before decreasing 8.7°F in the evening.

We can write as  .

Now According to the question , the temperature at evening will be :-

Hence, the evening temperature was .

Step-by-step explanation:

Given that one of the zeroes is 1 - i.

Complex roots occur in pairs.

This means, if a + bi is a zero of a polynomial, then a - bi is also its zero.

Therefore, 1 + i is also a zero of the polynomial.

Factors are x - (1 - i) and x - (1 + i).

Multiply the factors.

[x - (1 - i)][x - (1 + i)] = (x - 1 + i)(x - 1 - i)

Given that one of the zeroes is .

Irrational roots occur in pairs.

This means, if an irrational number m is a zero of a polynomial, then - m is also its zero.

Therefore, is also a zero of the polynomial.

Factors are and .

Multiply the factors.

Hence, the required polynomial is .
