The product of (3 + 2i) and a complex number is (17 + 7i). the complex number is?

Answers

Answer 1

Answer: Hello,

(3+2i)*x=17+7i
==>x=(17+7i)/(3+2i)
==>x=(17+7i)(3-2i)/((3+2i)(3-2i))
==>x=(65-13i)/13
==>x=5-i

Y^-3/y^-1 rewrite with positive exponetents

Answers

Answer:

Y/Y^3

Step-by-step explanation:

Negative exponents work like this: Y^-1 = 1/Y

We can apply this concept to our problem. Y^-3 would be 1/Y^3, and that is divided by 1/Y, so we flip the Y onto the numerator from the denominator and so we get Y/Y^3.

The volume of the Hawk’s refrigerator is 30 × 68 × 28.5 cubic inches.The volume of the Lopez’s refrigerator is (30 × 68 × 28.5) + 16 cubic inches.
Without doing any calculations, which statement describes how the volume of
the Hawk’s refrigerator compares to the Lopez’s refrigerator?

A.
The volume of the Hawk's refrigerator is 16 cubic inches greater than the volume of the Lopez's refrigerator.

B.
The volume of the Hawk's refrigerator is 16 times less than the volume of the Lopez's refrigerator.

C.
The volume of the Hawk's refrigerator is 16 times greater than the volume of the Lopez's refrigerator.

D.
The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.

Answers

The correct statement that describes how the volume of the Hawk's refrigerator compares to the Lopez's refrigerator is: Option D.

D. The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.

From the given information, we get,

The volume of the Hawk's refrigerator is given as 30 × 68 × 28.5 cubic inches.

The volume of the Lopez's refrigerator is given as (30 × 68 × 28.5) + 16 cubic inches.

We can see that the volume of the Lopez's refrigerator is obtained by adding 16 cubic inches to the volume of the Hawk's refrigerator.

Since 16 cubic inches are being added to the Hawk's refrigerator to get the Lopez's refrigerator, the volume of the Hawk's refrigerator must be 16 cubic inches less than the volume of the Lopez's refrigerator.

So, option D, "The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator," is the correct statement.

On a particular day, the wind added 2 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 2 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 44 miles with the wind, she could go only 36 miles against the wind.What is her normal rowing speed with no wind?

Answers

44-2x=36+2x
x=2
Since x = 2, we need to divide 40 by 2 to get the true value in mph
Which is:
20 mph
