Step-by-step explanation:

2400 skiers per hour

then in h hours h x 2400 skiers

in 14 hours 14x2400=33600 skiers

to move 3600 skiers we need 3600/2400=1.5 hours

Solve 4(x + 1) = 4x + 4. Would it be No solution? Or all real numbers?

arsen [322]

Pick any number. Write it in place of 'x'. If the result is a true statement, then your number is a solution of the equation. Do it again with a different number. Then do it again. Does it matter what your number is ?

Nadya filled a right rectangular prism with cubes that are 1/2 inch long each edge. She stacked 80 cubes in the prism and filled

vovangra [49]

Answer

<h2>The volume of right rectangular prism 10 cubic inch.</h2>

Step-by-step explanation:

The volume of cube $=a^{3}$

each edge of cube $=\frac{1}{2}$ inch

so,

the volume of cube $=\left [ \frac{1}{2} \right ]^{^{3}}$

one cube of volume $=\frac{1}{8}$ cubic inch.

$80$ cube of volume $=80\times\frac{1}{8}=10$ cubic inch

so the volume of rectangular prisme equal to volume of 80 cube.

Exponential growth/decay problem 2

lapo4ka [179]

Answer:

a) decay

b) 2,950,000

c) 0.025

d) $f(x)=2950000(0.975)^x$

e) 2,409,123

Step-by-step explanation:

Part (a)

Exponential DECAY, since the population was decreasing annually.

Part (b)

Initial amount = 2,950,000 people (in the year 2000)

Part (c)

Decay factor = 2.5% = 0.025 (in decimal form)

Part (d)

General form of exponential decay function:

$f(x)=a(1-r)^x$

where:

a = initial amount
r = rate of decay (in decimal form)
x = time (in years)

Given:

a = 2950000
r = 0.025

$\implies f(x)=2950000(1-0.025)^x$

$\implies f(x)=2950000(0.975)^x$

Part (e)

To determine the city's population in 2008:

$x = 2008 - 2000 = 8$

$\begin{aligned}\implies f(8) & =2950000(0.975)^8\\ & = 2409123\: \sf(nearest\:whole\:number)\end{aligned}$
