Allushta [10]

Answer:

Bess has been keeping track of the storm for 14 hours.

Step-by-step explanation:

The tropical storm has been moving at 15 miles per hour.

Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is

135+75=210

The relationship between distance speed and time is defined as

speed=\frac{distance}{time}

15=\frac{210}{time}

time=\frac{210}{15}

time=14

Therefore, Bess has been keeping track of the storm for 14 hours.

Digiron [165]

Answer:\frac{17}{35}

Step-by-step explanation:

Given

The bag contains 6 orange and 9 lime sweets

For both sweets of the same flavor, Jodi must either choose orange or lime

No. of ways it can be done is ^6C_1\times^5C_1+^9C_1\times^8C_1

The total no of ways of selecting two sweets out of 15 is ^{15}C_1\times^{14}C_1

The probability that both sweets are the same flavor

P=\dfrac{^6C_1\times^5C_1+^9C_1\times^8C_1}{^{15}C_1\times^{14}C_1}=\frac{102}{210}=\frac{51}{105}=\frac{17}{35}

What is the 2nd term when −3f3 + 9f + 6f4 − 2f2 is arranged in descending order?
Brilliant_brown [7]

For this case we have the following polynomial:

-3f ^ 3 + 9f + 6f ^ 4 - 2f ^ 2

To answer the question, what we must do is rewrite the polynomial in its standard form.

We have then that the polynomial will be given by:

6f ^ 4 - 3f ^ 3 - 2f ^ 2 + 9f

Therefore, we have the ordered polynomial in descending form of exponents.

Therefore, the second term of the polynomial is:

- 3f ^ 3

Answer:

The second term of the polynomial is given by:

- 3f ^ 3
