Answer:

21) 778240

22) 10804

23) 4862.03

Step-by-step explanation:

20.

x is months. There are 12 months in an year, so for this problem use x = 12.

190( 2^12) = 778240

21.

The equation for growth is:

initial_amount((1 + percent_in_decimal_form)^years)

So now equation is 10280(1.01^5) = 10804

22. Use same equation as in #21.

4000 (1.05 ^ 4) = 4862.03

Answer:

0,1

Step-by-step explanation:

Let n represent the first interger. and n+1 represent the next interger.

$n \times (n + 1) = 0$

${n}^{2} + n = 0$

Complete the square.

$( \frac{n}{2} {)}^{2} = \frac{ {n}^{2} }{4}$

${n}^{2} +n + \frac{ {n}^{2} }{4} = \frac{ {n}^{2} }{4}$

$(n + \frac{n}{2} ) {}^{2} = \frac{n {}^{2} }{4}$

Take the square root.

$(n + \frac{n}{2} ) = \frac{n}{2}$

$n = 0$

Plug 0 in for 0+1.

$0 + 1 = 1$

So the consective intergers are 0,1.

Answer:

b = 9 inches

Step-by-step explanation:

Given that,

The area of triangle LMN = 36 inch²

The height of the triangle, h = 8 inches

We need to find the base of the triangle. The formula for the area of a triangle is given by :

$A=\dfrac{1}{2}bh\\\\b=\dfrac{2A}{h}\\\\b=\dfrac{2\times 36}{8}\\\\b=9\ inches$

So, the base of the triangle is equal to 9 inches.

A quantity with an initial value of 4000 grows exponentially at a rate of 0.05% every 5 decades. What is the value of the quanti

icang [17]

The value of the quantity after 1 year, to the nearest hundredth is 4000.00

<h3>The exponential form of an equation</h3>

The standard exponential equation is eexpressed as:

$P(t)=P_0e^{kt}$

Given the following parameters

$P_0=4000\\r =0.0005\\t = \frac{1}{50} =0.02 (yearly)$

Substitute into the formula to have:

$P(t)=4000e^{0.0005(0.02)}\\P(1)=4000e^{0.00001}\\P(1)=4000$

Hence the value of the quantity after 1 year, to the nearest hundredth is 4000.00
