What is the distance between P(7, 0) and Q(8, 0)?

There is no change in the y axis, so it's a vertical distance, and 8-7=1, so the distance is 1

Answer:

$-9\frac{1}{4}$

Step-by-step explanation:

Rewrite our equation with parts separated

-5 - $\frac{3}{4}$ - 3 - $\frac{1}{2}$

Solve the whole number parts

-5 - 3 = -8

Solving the fraction parts and Find the LCD

LCD = 4

$-\frac{3}{4}$ - $\frac{2}{4}$ = $-\frac{5}{4}$

Simplify

$-\frac{5}{4} = -1\frac{1}{4}$

Combine the whole and fraction parts

8 - 1 - $\frac{1}{4}$ = $-9\frac{1}{4}$

Determine whether the integral is convergent or divergent. ∫[infinity] 2 e^−1/x / x^2 dx : O Convergent O divergent If it is con

monitta

Let $f(x)=e^{-1/x}$ . Then $f'(x)=\frac1{x^2}e^{-1/x}>0$ for all $x\ge2$ , so $f$ is strictly increasing. As $x\to\infty$ , $e^{-1/x}\to e^0=1$ , so $f$ is bounded above by 1. This is to say,

$e^{-1/x}$

and the integral of $\frac1{x^2}$ converges over the same domain, so this integral must also converge by comparison.

We have, by setting $y=-\frac1x$ ,

$\displaystyle\int_2^\infty\frac{e^{-1/x}}{x^2}\,\mathrm dx=\int_{-1/2}^0e^y\,\mathrm dy=e^0-e^{-1/2}=1-\frac1{\sqrt e}$

Given that (Triangle)MNO is similar to (Triangle)RST, determine the perimeter of (Triangle)RST.

blsea [12.9K]

Answer:

C

Step-by-step explanation:

Given that the 2 triangles are similar then the ratios of corresponding sides are equal.

This enables RT to be found, that is

$\frac{4}6}$ = $\frac{10}{RT}$ ( cross- multiply )

4RT = 60 ( divide both sides by 4 )

RT = 15

Hence

perimeter of ΔRST = 6 + 12 + 15 = 33 units
