1. The exponential function modeled below represents the number of square

Umnica [9.8K]

Answer:

600,000 km²

Step-by-step explanation:

Using the exponential regression calculator : the regression fit obtained for the data is :

36510 * (1.08^x)

After 40 years ;

x = 40

Hence,

y = 36510 * 1.08^40

y = 36510 * 21.72452

y = 793,162.27 km

Hence, y is closest to 800,000 km

PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1

Sedaia [141]

Answer:

a = 2, b = -4

Step-by-step explanation:

To make the given piecewise function continuous we need:

ax² - b = 6 and 5ax + b = 6 at x = 1

It gives us the system:

a(1²) - b = 6 ⇒ a - b = 6
5a(1) + b = 6 ⇒ 5a + b = 6

Sum of the two:

a - b + 5a + b = 6 + 6
6a = 12
a = 2

Then b is:

2 - b = 6
b = -4

A ream of paper contains 500 sheets of paper. Norm has 373 sheets of paper left from a ream. Express the portion of a ream Norm

Lunna [17]

Answer: In fraction : $\dfrac{373}{500}$

In Decimal : 0.746

Step-by-step explanation:

Given : A ream of paper contains 500 sheets of paper.

Norm has 373 sheets of paper left from a ream.

Then, the fraction of ream Norm has will be :-

$\dfrac{\text{Number of sheets left from ream }}{\text{Total sheets in a ream }}\\\\=\dfrac{373}{500}$

To convert in decimal we divide 373 by 500, we get 0.746.

Hence, The portion of a ream Norm has as = $\dfrac{373}{500}$ or 0.746
