I would go with graphing all of them, and see which includes the given points the most. That's the only way I've done it. Hope this helps!

Integral Calculation

Tatiana [17]

Answer:

$\frac{4}{3(e^2+1)}$

Step-by-step explanation:

We want to evaluate:

$\int\limits^1_{-1} {\frac{x^2+1}{e^2+1} } \, dx$

This is the same as:

$\frac{2}{e^2+1} \int\limits^1_{0} {x^2+1} \, dx$

We integrate to obtain:

$\frac{2}{e^2+1} (\frac{x^3}{3}+x)|_0^1$

We evaluate to obtain:

$\frac{2}{e^2+1} (\frac{1^3}{3}+1)=\frac{4}{3(e^2+1)}$

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find

notsponge [240]

So we need to cover 5.5% into a decimal.

0.055 = 5.5%

The house value is 120,000.
So

(1.055x) * (120,000)=

So

f(x)=1.055x * 120,000

The average distance between the Earth and the Moon is 384 400 km.<br> Express it in standard form.

ycow [4]

Answer:

$3.84\times10^8\ m$

Step-by-step explanation:

It is given that,

The average distance between the Earth and the Moon is 384 400 km.

We need to express in in standard form.

1 km = 1000 m

It means,

384400 km = 384400000 km

= $3.84\times10^8\ m$

Hence, the average distance between the Earth and the Moon is $3.84\times10^8\ m$ .
