Answer: m∠QPR = 40

<h2>Step-by-step explanation:</h2>

Because PG is perpendicular to PS, it is safe to assume that angle QPS is 90 degrees.

(7x-9) + (4x +22) = 90

x = 7

Because we need to find the degrees of QPR, plug in the equation for that angle with the value of x we found.

7(7) - 9 = 40

m∠QPR = 40

Find the area of a square if its sides measure 2 2/3m
olga55 [171]

Answer:

7\dfrac{1}{9}\ m^2

Step-by-step explanation:

If the length of the square side is a units, then the area of the square is

A=a^2\ un^2.

In your case, the side length is

a=2\dfrac{2}{3}\ m,

then the area is

A=2\dfrac{2}{3}\cdot 2\dfrac{2}{3}\\ \\ \\A=\dfrac{2\cdot 3+2}{3}\cdot \dfrac{2\cdot 3+2}{3}\\ \\ \\A=\dfrac{8}{3}\cdot \dfrac{8}{3}\\ \\ \\A=\dfrac{64}{9}\\ \\ \\A=7\dfrac{1}{9}\ m^2

Find the 52nd term of the following arithmetic sequence.<br> 3, 9, 15, 21,
Alex Ar [27]

Answer:

309

Step-by-step explanation:

a = 3, d = 6, n 52

Nth term of an Arithmetic sequence is given as:

t_n=a +(n-1)d \\  \therefore \: t_{52}=3 +(52-1) \times 6 \\ \therefore \: t_{52}=3 +51\times 6 \\  \therefore \: t_{52}=3 +306 \\   \huge \red{ \boxed{\therefore \: t_{52}=309 }}\\

What is the value of 9P5 ?
zalisa [80]
\bf _nP_r=\cfrac{n!}{(n-r)!}\qquad \qquad \qquad _9P_5=\cfrac{9!}{(9-5)!}

check your calculator for the [!] factorial button.

also bear in mind that most calculators also have an [ₙPᵣ] button, to get Permuations, and you can just use that.
