Answer:

Option D. -3.9 will be the answer.

Step-by-step explanation:

Change in weight of the whale in first week = (-2.1) pounds

Change in weight of the whale in second week = (+0.3) pounds

Change in weight of the whale in 3rd week = (-1.7) pounds

Change in weight of the whale in 4th week = -0.4 pounds

Total change in weight over the period of 4 weeks = - 2.1 + 0.3 - 1.7 - 0.4

= -3.9 pounds

Therefore, Option D. -3.9 will be the answer.

Answer:

923.1927 millibars

Step-by-step explanation:

The wind velocity is given by the function:

v(p)=5.7\sqrt{(998-p}

#We make p the subject of the formula:

v(p)=5.7\sqrt{(998-p}\\\\v=5.7\sqrt{(998-p}\\\\\frac{v}{5.7}=\sqrt{(998-p}\\\\\frac{v^2}{5.7^2}=998-p\\\\p=998-\frac{v^2}{5.7^2}

#Substitute the given values in the function above to solve for p;

p=998-\frac{v^2}{5.7^2}\\\\=998-\frac{49.3^2}{5.7^2}\\\\=923.1927\ millibars

Hence, the air pressure is 923.1927 millibars.

Choose the equation that satisfies the data in the table.
Zanzabum

Answer:

B. y = \frac{2}{15} X + 2

Step-by-step explanation:

I. Given x = 15 and y = 4

         4 = \frac{2}{15}(15) + 2

         4 = 2+2

         4 = 4 true

II. Give x = 0 and y = 2

         2 = \frac{2}{15}(0) + 2

         2 = 0 + 2

         2 = 2 true

III. Given x = -15 and y = 0

         0 = \frac{2}{15}(-15) + 2

         0 = -2 + 2

        0 = 0 true

Good luck.
