Answer:

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The volume of a cone is given by the formula

V=\frac{1}{3}\pi r^{2}h

we have

h=2x\ units\\r=x\ units

substitute

V=\frac{1}{3}\pi x^{2}(2x)

V=\frac{2}{3}\pi x^{3}\ units^3

Sidana [21]
Since there is a negative correlation, evident by the negative slope of the equation of the line given to be -0.5, if we take t as 0, we get an equation of,
                                            s = 3.6
This means that if a student does not watch television, he or she spends a maximum of 3.6 hours studying.

Answer:

B. $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :)
