Tito bought a baseball card for $24.00 and sold it for $37.00. what is the percent of increase rounded to the nearest tenth?

ladessa [460]

Answer: Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Cost price of a baseball card = $24

Selling price of a baseball card = $37

So, Profit would be

$37-24=\$13$

So, Profit % would be

$\dfrac{13}{24}\times 100\\\\=54.16\%\\\\\approx 54.2\%$

Hence, Option 'b' is correct.

Answer:

25%

Step-by-step explanation:

The percent of increase can be calculated using following formula:

$\text{Percent Increase}=\dfrac{\text{Final Amount-Initial Amount}}{\text{Initial Amount}}\cdot 100\%.$

In your case,

Initial amount = 12 students;
Final amount = 15 students,

then

$\text{Percent Increase}=\dfrac{15-12}{12}\cdot 100\%=\dfrac{3}{12}\cdot 100\%=\dfrac{1}{4}\cdot 100\%=25\%.$

Find the antiderivative for the function f(x) = (x – 11)(x + 13).<br><br> Please help

ziro4ka [17]

Expanding the product is simple enough:

$(x-11)(x+13)=x^2+2x-143$

Then

$\displaystyle\int(x-11)(x+13)\,\mathrm dx=\dfrac{x^3}3+x^2-143x+C$

We could also use a subsitution like $u=x-11$ , so that $u+24=x+13$ and $\mathrm du=\mathrm dx$ :

$\displaystyle\int u(u+24)\,\mathrm du=\int(u^2+24u)\,\mathrm du=\dfrac{u^3}3+12u^2+C$

$\implies\displaystye\int(x-11)(x+13)\,\mathrm dx=\dfrac{(x-11)^3}3+12(x-11)^2+C$

(which is differs from the first result by a constant, so it's still valid)
