Given the function h(x) = 3(5)x, section a is from x = 0 to x = 1 and section b is from x = 2 to x = 3. part

katrin2010 [14]

A.
h(x)=3*5ˣ; h(0)=3, h(1)=15: rate of change is (15-3)/1=12 (1st section)
h(2)=3*25=75, h(3)=3*125=375: rate of change (375-75)/1=300 (2nd section)
b.
So the second section is 300/12=25 times greater than the first section.
The function is exponential and as x gets larger the difference between consecutive values of h(x) increases dramatically so the rate of change increases.

Melissa and Emily are playing at the pool.They have three different measuring jars for; liters, cups, and pints. They find that

Deffense [45]

7 cups + 3 litres = 9.8 pints
$7c+3l=9.8p$ ⇒ Equation 1

5 litres - 9 cups = 6 pints
$5l-9c=6p$ ⇒ Equation 2

Relationship between cups and litres
Rearranging equation 1 to make pints the subject
$7c+3l=9.8p$
$p= \frac{7c+3l}{9.8}$ ⇒ substitute this into Equation 2

$5l-9c= \frac{7c+3l}{9.8}$
$49l-88.2c=7c+3l$
$49l-3l=7c+88.2c$
$46l=95.2c$
$l=2.1c$

Hence, 1 litre = 2.1 cups

Relationship between cups and pints
Rearrange equation 1 to make litres the subject
$7c+3l=9.8p$
$3l=9.8p-7c$
$l= \frac{9.8p-7c}{3}$ ⇒ Substituting this into Equation 2

$5( \frac{9.8p-7c}{3})-9c=6p$
$\frac{49p-35c}{3}-9c=6p$
$\frac{49}{3}p- \frac{35}{3}c-9c=6p$
$\frac{49p}{3}-6p= \frac{35}{3}+9c$
$\frac{31}{3}p= \frac{62}{3}c$
$p=2c$

Hence, 1 pint = 2 cups

Relationship between pints and litres
Rearranging equation 1 to make cup the subject

$7c=9.8p-3l$
$c= \frac{9.8p-3l}{7}$ ⇒ subsitute this into equation 2

$5l-9( \frac{9.8p-3l}{7})=6p$
$5l- \frac{63}{5}p+ \frac{27}{7}l=6p$
$5l+ \frac{27}{7}l=6p+ \frac{63}{5}p$
$\frac{62}{7}l= \frac{93}{5}p$
$l=2.1p$

Hence, 1 litre = 2.1 pints

Find the values of both x and y?

dlinn [17]

$Answer: \\ 2x + 3y = 12 \: \vee \: 30x + 11y = 112 \\\Leftrightarrow 30x + 45y = 180 \: (1)\: \vee \:30x + 11y = 112 \: (2) \\ (1) - (2)\Rightarrow 34y = 68\Rightarrow y = 2 \\ 2x + 3 \times 2 = 12\Rightarrow x = 3$

Un empresario compró 1000 tabletas a $1500 cada una. Vendió 450 de ellas obteniendo una

marishachu [46]

Answer:

Step-by-step explanation:

1000($1500(0.40)) = $600 000

450($1500(0.25)) = $168,750

600,000 - 168,750 = $431,250

$431,250 / 550 = 784.0909090... $784.09

$1500 + $784.09 = $2,284.09
