Which of the following represents
this number in scientific notation?
-0.904
A. 9.04 • 10^-1
B. -9.04 • 10^1
C. -9.04 • 10^-1
D. -9.04 • 10^-3

Answers

Answer 1

Answer:

The correct option is (c).

Step-by-step explanation:

The given number is -0.904.

We need to represent the number in scientific notation.

Any number can be written in scientific notation as follows :

[tex]a\times 10^b[/tex]

Where

a is a real number and b is an integer

We can write it as follows :

[tex]-0.904=-9.04\times 10^{-1}[/tex]

Hence, the correct option is (c).

4.Solveby any algebraic method. Work must be shown.

Answers

Answer:

The test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.

Step-by-step explanation:

Since, on a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions, the test is worth a total of 100 points and there are twice as many 2-point questions as 5- point questions on the test, to determine how many 2-point questions are on the test, the following calculation must be performed:

18 x 2 + 9 x 5 + 1 x 4 = 36 + 45 + 4 = 85

16 x 2 + 8 x 5 + 4 x 4 = 32 + 40 + 16 = 88

14 x 2 + 7 x 5 + 7 x 4 = 28 + 35 + 28 = 91

12 x 2 + 6 x 5 + 10 x 4 = 24 + 30 + 40 = 94

10 x 2 + 5 x 5 + 13 x 4 = 20 + 25 + 52 = 97

8 x 2 + 4 x 5 + 16 x 4 = 16 + 20 + 64 = 100

Thus, the test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.

What is the multiplicative inverse of y?

Answers

Step-by-step explanation:

The multiplicative inverse of an expression is its reciprocal. It is the value that, when multiplied by the original, give a product of 1 (the multiplicative identity element).

Here, that is ...

  1/y

because (y)(1/y) = y/y = 1.

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 115,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 6% each year. How many total fish did the company catch over the first 20 years, to the nearest whole number? ​

Answers

Answer:

Rounded to the nearest whole number, the company caught 1,360,630 fish in total over the 20 years.

Step-by-step explanation:

Given that a major fishing company does its fishing in a local lake, and the first year of the company's operations it managed to catch 115,000 fish but due to population decreases, the number of fish the company was able to catch decreased by 6% each year, to determine how many total fish did the company catch over the first 20 years, to the nearest whole number, the following calculation must be performed:  

Year 1: 115,000

Year 2: 115,000 x 0.94 = 108,100

Year 3: 108,100 x 0.94 = 101,614

Year 4: 101,614 x 0.94 = 95,517.16

Year 5: 95,517.16 x 0.94 = 89,786.13

Year 6: 89,786.13 x 0.94 = 84,398.96

Year 7: 84,398.96 x 0.94 = 79,335.02

Year 8: 79,335.02 x 0.94 = 74,574.92

Year 9: 74,574.92 x 0.94 = 70,100.42

Year 10: 70,100.42 x 0.94 = 65,894.40

Year 11: 65,894.40 x 0.94 = 61,940.73

Year 12: 61,940.73 x 0.94 = 58,824.29

Year 13: 58,824.29 x 0.94 = 54,730.83

Year 14: 54,730.83 x 0.94 = 51,446.98

Year 15: 51,446.98 x 0.94 = 48,360.16

Year 16: 48,360.16 x 0.94 = 45,458.55

Year 17: 45,458.55 x 0.94 = 42,731.03

Year 18: 42,731.03 x 0.94 = 40,167.17

Year 19: 40,167.17 x 0.94 = 37,757.14

Year 20: 37,757.14 x 0.94 = 35,491.71

TOTAL: 1,360,629.60

Thus, rounded to the nearest whole number, the company caught 1,360,630 fish in total over the 20 years.

PLEASE HELP WITH THE FOLLOWING. WILL GIVE BRAINLIEST. THANK YOU

Answers

Answer:

50.8°

Step-by-step explanation:

First, we need to use the Pythagorean Theorem to find the third side. We will then use the law of cosines to find the angle.

2√15² = 2√6² + b²

60 = 24 + b²

Subtract 24

36 = b²

b = 6

Now, that we have all three sides, we will use the law of cosines to figure out the angle.

c² = a² + b² - 2abCosC°

Substitute the values in.

6² = 2√15² + 2√6² - 2(2√15)(2√6)CosC°

36 = 60 + 24 - 2(37.947331922)CosC°

36 = 60 + 24 - 75.894663844CosC°

36 = 84 - 75.894663844CosC°

Subtract 84

-48 = -75.9CosC°

0.63241106719 = CosC°

Arccos (0.63241106719) = 50.77176844°

The largest acute angle is approximately 50.8°

Four pounds of apples cost $5. Eight pounds of apples cost $10. If the total cost of apples, y, varies directly with the number of pounds of apples purchased, x, what is the cost of 6 pounds of apples? Round your answer to the nearest hundredth.

$0.80
$1.25
$4.80
$7.50

Answers

Cost of apples, y, varies directly with pounds

of apples purchased, x.

y = kx

k is constant of proportion

Four pounds of apples cost $5

5 = 4k

k = 5/4 = 1.25

10 = 8k

k = 10/8 = 1.25

As it should be, k is a constant equal to 1.25

y = 6(1.25) = $7.50 for 6 pounds of apples

Evaluate the following
Lim (xcotx)

Answers

Answer:

1

Step-by-step explanation:

Evaluate the following

Lim (xcotx)

x->0

Note that cotx = cosx/sinx

The expression becomes

Lim (xcotx) = Lim (xcosx/sinx)

x->0               x->0

= 0cos0/sin0

= 0/0 )(ind)

Apply l'hospital rule

= Lim d/dx(xcosx/sinx)

x->0          

= lim (-xsinx + cosx)/cosx

    x->0

= -0sin0+cos0/cos0

= 0+1/1

= 1/1

= 1

Hence the limit of xcotx as x tends to zero is 1

the total cost of kurts required textbooks this quarter is $342.50. optional textbooks cost a total of $65.25. whicg inequality shows the total cost C that kurt could pay for his textbooks?

Answers

Answer:

342.5 + 65.25 = C

407.75 = C

Step-by-step explanation:

Given that the total cost of Kurt's required textbooks this quarter is $ 342.50, while optional textbooks cost a total of $ 65.25, to determine which inequality shows the total cost C that Kurt could pay for his textbooks, the following mathematical reasoning must be performed:

Mandatory books + optional books = Cost

342.5 + 65.25 = C

407.75 = C

Thus, Kurt could pay a total cost of $ 407.75 for his textbooks this quarter.

Suppose you deposit 900 dollars into a bank with 5% simple interest. The amount in the account after t years is given by A(t)=900(1.05)t (in dollars).
1. What is the average rate of change for the first year? Rate (in dollars per year): 900(1.05)-900
2. What is the average rate of change for the first five years? Rate (in dollars per year):
3. What is the average rate of change for the first ten years? Rate (in dollars per year):
4. Does the average rate of change increase or decrease as time from the initial deposit gets longer?

Answers

Answer:

1. 45 dollars per year.

2. 49.73 dollars per year.

3. 56.6 dollars per year.

4. Increases

Step-by-step explanation:

Average rate of change

The average rate of change of a function [tex]f(x)[/tex] over an interval [a,b] is given by:

[tex]A = \frac{f(b)-f(a)}{b-a}[/tex]

In this question, we have that:

[tex]A(t) = 900(1.05)^t[/tex]

1. What is the average rate of change for the first year?

[tex]A(0) = 900(1.05)^0 = 900[/tex]

[tex]A(1) = 900(1.05)^1 = 945[/tex]

So

[tex]A = \frac{A(1)-A(0)}{1-0} = \frac{945-900}{1-0} = 45[/tex]

45 dollars per year.

2. What is the average rate of change for the first five years?

[tex]A(0) = 900(1.05)^0 = 900[/tex]

[tex]A(5) = 900(1.05)^5 = 1148.65[/tex]

[tex]A = \frac{A(5)-A(0)}{5-0} = \frac{1148.65-900}{5-0} = 49.73[/tex]

49.73 dollars per year.

3. What is the average rate of change for the first ten years?

[tex]A(0) = 900(1.05)^0 = 900[/tex]

[tex]A(10) = 900(1.05)^{10} = 1466[/tex]

[tex]A = \frac{A(10)-A(0)}{10-0} = \frac{1466-900}{10-0} = 56.6[/tex]

56.6 dollars per year.

4. Does the average rate of change increase or decrease as time from the initial deposit gets longer?

From the previous items, it increases.
