Answer:

1.8

Step-by-step explanation:

The point of intersection of the left-side function with the right-side function is the value of x where the two functions evaluate to the same quantity. That value of x is near 1.785, as indicated on the attached graph. Rounded to the nearest tenth, the value of x is 1.8.

_____

<em>Refinement of the graphical solution</em>

An iteration method called Newton's Method can be used to refine the estimate to the limit of accuracy of the calculator. For that, it is convenient to define a function such as the one you get when you subtract the right side from the left side. Newton's Method is good at finding the zero(s) of such a function.

The function defined as g(x) in the attachment is the iterator for Newton's Method. It gives the next "guess" based on the guess you give it as an argument. When there is no change, the guess is as accurate as the calculator can provide. Here, that refined estimate of x is x ≈ 1.78522264685.

The Lions won 16 games last year this year the Lions won 20 games what is the percent increase in the number of games of the lio

-BARSIC- [3]

So to find a percent of increase you have to put the current number minus previous number(in this case 20-16) over the previous number(16 in this case) and multiply by 100.
So we have 20-16/16 multiplied by 100.
Since 4/16= 0.25,multiplying It by 100 gives you 25.
So the answer is 25%

a recreation park measurers 560m long and 700m wide. A 250m and 150m area of the park is used for soccer and baseball filed .How

Triss [41]

Answer: 354500m²

Step-by-step explanation:

Area of the recreation park = 560m x 700m

= 392000m²

Area used for soccer and baseball = 250m x 150m

= ¹⁵⁰⁰⁰⁰/₄

= 37500m².

Area of the remaining park = 392000 - 37500

= 354500m²

White raven [17]

The greatest number of gift basket the baker can make is 8. Since there are 80 rolls and 64 muffins and he wants each gift basket to have the same amount of rolls and muffins and use all the rolls and muffins, there would be 10 rolls and 8 muffins in each gift basket.
