Alex usually runs for 21 hours a week, training for a marathon. If he is unable to run for 3 days, describe how to find out how many hours of training time he loses, and write the appropriate integer to describe how it affects his time

Answers

Answer 1
Answer: Alex usually runs for 21 hours a week.  We know that there are 7 days in a week.  21/7 = 3, which means that Alex runs for 3 hours each day.

We are trying to figure out how much time he loses if he is unable to run for three days.  3 * 3 = 9.  This means he loses 9 hours of training while he is unable to run.

Answer 2
Answer: Assuming he runs the same number of hours per day, then he runs 3 hours per day (21/7). 
If he runs 3 hours a day, then in 3 days he would have ran 9 hours (3*3). 

He loses 9 hours of training if he doesn't run for 3 days.

Which is the graph of the function f(x) = x2 + 2x + 3?

Answers

Answer:

Refer the graph attached.

Step-by-step explanation:

Given : Equation f(x) = x^2 + 2x + 3  

To find : The graph of the given equation?

Solution :  

Let,y= x^2 + 2x + 3  

First we find the points which satisfy the equation and then joining those points give you the graph.

Points are

What plus what equals 160

Answers

The equation to show the sum of two number is 160: x + y = 160.

An equation is a mathematical statement that shows that two expressions are equal.

To find two numbers that add up to 160, we can Set up an equation with two unknowns, x and y, representing the two numbers:

x + y = 160

Since there are infinitely many possible combinations of two numbers that add up to 160.

Some combinations are:

1. x = 80, y = 80

80 + 80 = 160

2. x = 50, y = 110

50 + 110 = 160

3. x = 30, y = 130

30 + 130 = 160

4. x = -20, y = 180

-20 + 180 = 160

5. x = 0, y = 160

0 + 160 = 160

These are just a few examples, and there are many other combinations of numbers that satisfy the equation x + y = 160.

80 plus 80 is equal to 160. It's like 8 plus 8 equals 16, just add a zero to the end to each numbers it's easier to think that way

The 2020 Election is shaping up to be the largest one yet! They estimate that there are 240,000,000 eligible voters in the United States this year. So far, 70,000,000 have voted, and experts estimate that upwards of 150,000,000 people will vote in total this year. What percentage of eligible voters will participate in this year's election?

Answers

Answer:

Percentage = 91.67%

Step-by-step explanation:

Number of eligible voters = 240,000,000

Number of voters so far = 70,000,000

Number of estimated voters = 150,000,000

Total number of participants (voters) = 70,000,000 + 150,000,000 = 220,000,000

To find the percentage;

Percentage = \frac {220,000,000}{240,000,000} * 100

Percentage = \frac {11}{12} * 100

Percentage = 0.9167 * 100

Percentage = 91.67%

Therefore, the percentage of eligible voters that will participate in this year's election is 91.67%

What is the general solution for (cosX + sinX)(1 - 2sinX)=0

Answers

1. square both sides, a straight forward method. 
2. hand plot 
3. calculator plot, not recommended.Let Y=sin x + cos x -1 
Y=0, find x=? 
4. Substitute 1=sin^2(x) + cos^2(x) on the right hand side 
Y1=sin^2(x) - sin(x) 
Y2=cos^2(x) - cos(x) 
Y1 + Y2=0, Y1=0, Y2=0, 
a(a-1)=0, so, a=0, a=1, where a=sin(x), or cos(x), 
so x=0, pi/2
