If there is a decrease on y then that’s the answer

Since I can't see the graph, I can't choose exactly, but if:

1. as x rises, y falls

and

2. there is no one slope (there is one curve)

then it represents exponential decay.

Aka. it's a downward woosh.

Answer:

PQ = $PM\cos MPQ + MQ\cos MQP=2PM\cos MQP$

Step-by-step explanation:

given MQR = 60, PQR = 75

MQP = 75 -60= 15 $QR = ((18(1+\cos 30))^{2}-(2\cos 15)^{2})^{\frac{1}{2}}$

WE KNOW THAT MQR +QRM +QMR = 180

MPQ = MQP AS ANGLE OPPOSITE TO EQUAL SIDES ARE EQUAL

THEREFORE QMR = 90 - 60 = 30

therefore PQM = 75 - 60 = 15

PM = PQ because M is the mid point

therefore PR = PM + $MQ\cos QMR$

PR = $18(1+\cos 30)$

$QR = (PR^{2}-PQ^{2}))^{\frac{1}{2}}$

PQ = $PM\cos MPQ + MQ\cos MQP=2PM\cos MQP$

Calcula el ancho de un terreno rectangular si el largo mide 20 metros y la superficie es de 280 metros cuadrados

Anna35 [415]

Answer:14 m

Step-by-step explanation:

Dada

larga $l=20\ m$

superficie $A=280\ m^2$

Suponga que el ancho es w

La superficie está dada por el producto de la longitud y la anchura.

$\therefore A=lw\\\Rightarrow 280=20\times w\\\Rightarrow w=14\ m$

Por lo tanto, el ancho es de 14 m.

Verizon [17]

Answer:

Step-by-step explanation:

So first you add them together which gives you infinity and then you divide infinity by (139+285) then keep doing it until you realise this is a scam
