In 2005, it took 18.54 currency units to equal the value of 1 currency unit in 1915. In 1990, it took only 13.30 currency units

to equal the value of 1 currency unit in
1915. The amount it takes to equal the value of 1 currency unit in 1915 can be estimated by the linear function V given by V(x) = 0.3584x + 13.9132, where x is the
number of years since 1990. Thus, V(11) gives the amount it took in 2001 to equal the value of 1 currency unit in 1915. Complete parts (a) and (b) below.
a) Use this function to predict the amount it will take in 2008 and in 2017 to equal the value of 1 currency unit in 1915.
In 2008, it will take currency units.
(Round to two decimal places as needed.)

Answer:

2008 - 1990 = 18

x = 18

v(x) = 0.3584x + 13.9132

= 0.3584 × 18 + 13.9132

= 6.4512 + 13.9132 = 20.3644 = 20.36

in 2017

2017 - 1990 = 27

= 9.6768 + 13.9132 = 23.59

The radius of a circle is 12 miles. What is the angle measure of an arc bounding a sector with area 10​ square miles?
hram777 [196]

\bf \textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ A=10\\ r=12 \end{cases}\implies 10=\cfrac{\theta \pi 12^2}{360}\implies 10=\cfrac{2\pi \theta }{5} \\\\\\ 20=2\pi \theta \implies \cfrac{20}{2\pi }=\theta \implies \cfrac{10}{\pi }=\theta \implies 3.18\approx \theta

The expression 8x2 − 144x 864 is used to approximate a small town's population in thousands from 1998 to 2018, where x represent
Rzqust [24]

The expression that is most useful for finding the year where the population was at a minimum would be 8(x − 9)² + 216.

Given expression 8x² − 144x + 864 is used to approximate a small town's population in thousands from 1998 to 2018, where x represents the number of years since 1998.

<h3>What is a quadratic equation?</h3>

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given expression is 8x² − 144x + 864

Let y = 8x² − 144x + 864

also,  y - 864 = 8x² - 144x

by Extracting common factor 8 on the right side

y - 864 = 8(x² - 18x)

Add (18/2)² on both sides, we get

y - 864 + 8(18/2)² = 8 (x² - 18x + 81²)

y - 864 + 648 = 8 (x² - 8x + 9)

on simplification

y - 216 = 8 (x - 9)²

y = 8(x - 9)² + 216

therefore, y = 8 (x - 9)² + 216

The expression that is most useful for finding the year where the population was at a minimum would be 8(x − 9)² + 216.
