Answer:

  A.  3/8 ft

  B.  width would decrease

Step-by-step explanation:

A. The area of a rectangle is given by the formula ...

  A = LW

Solving for W, we find ...

  W = A/L . . . . . width is inversely proportional to length for the same area

Using the given dimensions, we find the width to be ...

  W = (3/10 ft²)/(4/5 ft) = (3/10)(5/4) ft

  W = 3/8 ft

The width of the card is 3/8 ft.

__

B. Width is inversely proportional to length for the same area, so an increase in length would result in a decrease of width.

What is f(x)=2(3)^x?
HACTEHA [7]

Answer:

This is an exponential function

Step-by-step explanation:

f(x)=2(3)^x is one example of the exponential function.  Since f(0) = 2(1) = 2, the y-intercept is (0, 2).  The x-axis is the horizontal asymptote.  The graph begins in Quadrant II, passes through (0, 2) and continues to increase, faster and faster, in Quadrant I.  Next time, please be more specific about what you'd like to know.

Solve the following equation for <br><br><br> G:2 (g-h) = b+4
Klio2033 [76]

If the equation 2(g - h) = b + 4 is solved for g. Then the value of g will be b/2 + h + 2.

<h3>What is the solution of the equation?</h3>

A combination of equations solution is a collection of values x, y, z, etc. that enable all of the calculations to true at the same time.

The equation is given below.

2(g - h) = b + 4

Then solve the equation for the value of g. Then we have

2(g - h) = b + 4

   g - h = b/2 + 2

        g = h + b/2 + 2

More about the solution of the equation link is given below.

Consider a total of 1,000 people. If it was said that within 1 deviation (of the mean) of all people like MATH 123, how many of
Lesechka [4]

Answer:

680 students

Step-by-step explanation:

The 68 - 95 - 99.7  rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean,  95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.

Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:

number of people that like MATH 123 = 68% of the population

number of people that like MATH 123 = 0.68 * 1000

number of people that like MATH 123 = 680 students
