Someone help! you have 44 text messages in your inbox. How many messages can your cell phone hold? (and inbox is 88% full)

marin [14]

We can set up a proportion.

88% = 0.88

44/0.88 = x/1

Cross multiply:

0.88x = 44

Divide 0.88 to both sides:

x = 50

So your cell phone can hold 50 messages.

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?

Ne4ueva [31]

A because (0,-6) is the y-intercept so you start at the point you know. Then because slope is a rise over run fraction the slope can also be written as 2/1 which is rise 2 over 1.

Use Part 1 of the Fundamental Theorem of Calculus to find the derivative of the function. g(x) = 7x u2 − 1 u2 + 1 du 6x Hint: 7x

VikaD [51]

It looks like you're given

$g(x)=\displaystyle\int_{6x}^{7x}\frac{u^2-1}{u^2+1}\,\mathrm du$

Then by the additivity of definite integrals this is the same as

$g(x)=\displaystyle\int_0^{7x}\frac{u^2-1}{u^2+1}\,\mathrm du-\int_0^{6x}\frac{u^2-1}{u^2+1}\,\mathrm du$

(presumably this is what the hint suggests to use)

Then by the fundamental theorem of calculus, we have

$\dfrac{\mathrm dg}{\mathrm dx}=7\dfrac{(7x)^2-1}{(7x)^2+1}-6\dfrac{(6x)^2-1}{(6x)^2+1}=\dfrac{1764x^4+169x^2-1}{1764x^4+85x^2+1}$

Bill is saving for his son's college education. If the savings account earns 5% interest compounded monthly, and he wants to hav

Otrada [13]

Total money that will be in the account in 10 years = 45000

Time period = 10 years

Rate of interest = 5% or 0.05

n = 12 (number o times the money is compounded)

Let the principal (p) be = x

Formula for compound interest = $A=p(1+\frac{r}{n})^{nt}$

Putting the values in the formula we get,

$45000=x(1+\frac{0.05}{12})^{10*12}$

$45000=x(\frac{12+0.05}{12})^{120}$

$45000=x(1.004)^{120}$

$45000=1.614x$

$x=27881.04$

Hence, the principle amount should be approximately $27881.

The Frostburg-Truth bus travels on a straight road from Frostburg Mall to Sojourner Truth Park. The mall is 3 miles west and 4 m

geniusboy [140]

We take the distance from points which indicates the location of the park and the mall.

For distance through north and east, we have positive values and negative for west and south.

Mall: (-3, -4)
Park: (3, 5)

The distance is calculate through the equation,
d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)

Substituting,
d = sqrt ((-4 - 5)² + (-3 - 3)²
d = sqrt 117 = 10.82
Thus, the distance between the mall and the park is approximately 10.82 miles.
