Answer:

1.80 dollars per kilogram of candy.

Step-by-step explanation:

How to get this is simple and you will use it later in life, you take the price of the candy you paid for, then you divide it by the amount in pounds, or kilograms, to get the price per pound.

2.25 / 1.25 = 1.80

Cheers!

What is the answer to 8(t+2)-3(t-4)=6(t-7)+8

Natasha_Volkova [10]

If you're just looking for the simplified equation that would be : 5t + 28 = 6t - 34

But if you're looking to find the value of "t" that would be : t = 62

If then, you are looking for the answer to the equation with t inserted, the equations are equal both sides equal : 338

I hope that answered your question. If not, lmk.

Integrate the following

enot [183]

I suppose you mean to have the entire numerator under the square root?

$\displaystyle\int_2^4\frac{\sqrt{x^2-4}}{x^2}\,\mathrm dx$

We can use a trigonometric substitution to start:

$x=2\sec t\implies\mathrm dx=2\sec t\tan t\,\mathrm dt$

Then for $x=2$ , $t=\sec^{-1}1=0$ ; for $x=4$ , $t=\sec^{-1}2=\frac\pi3$ . So the integral is equivalent to

$\displaystyle\int_0^{\pi/3}\frac{\sqrt{(2\sec t)^2-4}}{(2\sec t)^2}(2\sec t\tan t)\,\mathrm dt=\int_0^{\pi/3}\frac{\tan^2t}{\sec t}\,\mathrm dt$

We can write

$\dfrac{\tan^2t}{\sec t}=\dfrac{\frac{\sin^2t}{\cos^2t}}{\frac1{\cos t}}=\dfrac{\sin^2t}{\cos t}=\dfrac{1-\cos^2t}{\cos t}=\sec t-\cos t$

so the integral becomes

$\displaystyle\int_0^{\pi/3}(\sec t-\cos t)\,\mathrm dt=\boxed{\ln(2+\sqrt3)-\frac{\sqrt3}2}$
