Ian walked 4 miles in 90 minutes. Bob walked 7 miles in 2.5 hours. Are these rates in proportion? If no, who walked faster?

Answers

Answer 1

Answer:

Bob walked faster than Ion.

Step-by-step explanation:

90/4=22.5

Ian - 1 mile in 22.5 minutes

2x60=120

60/2=30

120+30=150

150/7=21.43

Bob - 1 mile in 21.43

Answer 2

Answer:

They are not the same because Ian - 1 mile in 22.5 minutes and Bob - 1 mile in 21.43

On what interval(s) of x is f(x) positive?

On what interval(s) of x is f(x) negative?

Answers

Answer:

Positive: (-2,1)

Negative: (-∞,-2) U (1,∞)

Step-by-step explanation:

The graph of the function f(x) is given in the figure. We can see some points like (-2,0), (-1,1), (2,-2), and many others.

Note the second value of each point (the value of y) is positive or negative. When it's positive, the graph is above the x-axis, when it's negative, the graph is below the x-axis. When it's 0, the graph crosses the x-axis.

To find the intervals of x where the function is positive, we only have to look into the zone where the graph is above the x-axis. It can be identified as the interval (-2,1).

Similarly, the function is negative in the interval (-∞,-2) U (1,∞)

The function f(x) is positive in the interval [-2, 1].

The function f(x) is negative the interval (-∞, -2) U (1, ∞).

The positive regions of a function f(x) are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero).

To find the intervals of x where the function is positive,

In the interval [-2, 1] , the function f(x) is positive.

The negative regions of a function f(x) are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).

In the interval (-∞,-2) U (1,∞) , the function f(x) is negative.

y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.

when y = 0, x = -2, 1

Therefore, the function f(x) is positive in the interval [-2, 1] and negative in the interval (-∞,-2) U (1,∞).

What is 2 to the 400th power factorial?

Answers

Step-by-step explanation:

2^400=2^(2×200)

2^(2×200) =[2^(2) ]^200

Now, [2^(2) ]^200=4^200

The power  of 2 in 400! is 397.

What is the method of determination of power of prime in Factorial ?

Let p is the prime number whose power is to be found

Let n is the factorial number then

p in n! = (n /p) + (n/p²) +(n/p³) + .......

until Numerator < Denominator

and after division only the integer part is taken

Therefore to determine the power of 2 in 400!

2 in 400! = (400 /2) + ( 400 /2²) + (400 /2³) +(400 /2⁴) +(400 /2⁵) +(400 /2⁶) +(400 /2⁷) +(400 /2⁸) + above this N < D

2 in 400! = 200 +100 +50+25+12+6+3+1

2 in 400 = 397

Therefore the power  of 2 in 400! is 397.

Answer:

Step-by-step explanation:

6x−13=2x+7

Inverse operation:

6x into a negative then subtract it by 2x

2x - 6x = -4

Change 7 into a negative then subtract it by -13

-13 - 7 = -20

Answer:

  y = 4x +3

Step-by-step explanation:

The slope formula can be used to find the slope:

  m = (y2 -y1)/(x2 -x1)

Using the first two lines of the table, we find the slope to be ...

  m = (11 -7)/(2 -1) = 4/1 = 4

__

The y-intercept can be found from the relation ...

  b = y -mx

Using the slope we found, and the first line of the table, we find the intercept to be ...

  b = 7 -4(1) = 3

__

Then the equation is ...

  y = mx +b . . . . . . slope-intercept form of the equation for a line

  y = 4x +3
