Find the Quotient and Remainder. 5x^3 - 6x^2 + x + 7 divided by x^2

12345 [234]

Step-by-step explanation:

Solution

According to remainder theorem, when f(x) is divided by (x+2), Remainder =f(−2)

f(x)=5x3+2x2−6x+12

f(−2)=5(−2)3+2(−2)2−6(−2)+12

=5×−8+2×4+12+12

=−40+32=−8

∴ Remainder=−8

snow_lady [41]

Answer:

2.5 years

Step-by-step explanation:

Given data

P=9000

r= 1.25%

A= 9281.25

The simple interest expression is given as

A=P(1+rt)

substitute

9281.25= 9000(1+0.0125*t)

9281.25=9000+112.5t

collect like terms

9281.25-9000=112.5t

281.25= 112.5t

t= 281.25/112.5

t= 2.5

Hence the time is 2.5 years

John and Kamira are playing a game. John's score (J) and Kamira's score (K) after round 1 are shown on the number line.

The score recorded at the end of the first round is 2.

What could this score represent?

Options :

the sum of John's score and Kamira's score

the difference between John's score and Kamira's score

the absolute value of the difference of John's score and Kamira's score

the sum of the absolute value of John's score and the absolute value of Kamira's score

Answer:

the sum of John's score and Kamira's score

Step-by-step explanation:

Given that :

The score recorded at the end of the round is 2

From the attached number line :

John's score = - 5

Kamira's score = 7

Sum = - 5 + 7 = 2

Difference = - 5 - 7 = - 12

Sum of absolute value = 5 + 7 = 12

absolute value of difference = 12
