The distance between -32 and
13

Answers

Answer: To find the distance between -32 and 13, we need to calculate the absolute difference between the two numbers.

The absolute difference is the positive value of the subtraction of one number from another. In this case, we subtract -32 from 13.

13 - (-32) = 13 + 32 = 45.

Therefore, the distance between -32 and 13 is 45 units.

From c to the midpoint the coordinates have changed from (-1;9) to (-9;-10). So the difference is (-9-(-1); -10-(9)) that equals (-8;-19). And you should add (-8;-19) to the coordinates of the middle point (-9;-10). So we get (-9+(-8); -10+(-19)) that is (-17;-29). This is the endpoint of d. Answer: d (-17;-29).

What is the largest factor of 16 that is also a perfect cube?

Answers

The largest factor of 16 that is also a perfect cube is 2. When you factor out 16, you will get 4 times 4 and then factor out 4, you will also get 2 times 2 times 2 times 2. Other factors for 16 is 8 times 2 which can be further divided into 2 times 2 times 2 times 2. When you factor out 8, you get 2 times 2 times 2 and so 2 is a perfect cube.

In a recent year a letter to Europe from United date cost $ 0.94 to mail a letter mailed within the United States cost $0.44 nancy mailed for $3.70 some to Rourke and some to United States how many letter did she send to europe

Answers

Answer: she mailed 3 letters to Europe

Step-by-step explanation:

Let x represent the number of letters that Nancy mailed to Europe.

Let y represent the number of letters that Nancy mailed to United States.

Nancy mailed 5 letters, some to Europe and some to the United States. This means that

x + y = 5

A letter mailed within the United States costs $0.44. A letter to Europe from United date cost $ 0.94 to mail. If the letters that Nancy mailed cost $3.70, then

0.94x + 0.44y = 3.7 - - - - - - - - - - - -1

Substituting x = 5 - y into equation 1, it becomes

0.94(5 - y) + 0.44y = 3.7

4.7 - 0.94y + 0.44y = 3.7

- 0.94y + 0.44y = 3.7 - 4.7

- 0.5y = - 1

y = - 1/ - 0.5 = 2

x = 5 - y = 5 - 2

x = 3

A colony of bacteria is growing exponentially according to the function below, where t is in hours. What will the approximate number of bacteria after 7 hours? B(t)=4*e^0.8t Answers: A. 45,674 / B. 1082 / C. 270 / D. 635,818

Answers

We are given with the situation of bacteria multiplying into colonies. We are given also with the function of B(t)= 4e^0.8t where t is the time of multiplication. We just have to substiture the given time of 7 hours to find teh final count. The answer is approximately 1082. Answer is B.
