Select the angle that correctly completes the law of cosines for this triangle. 72 + 252 – 2(7)(25)cos ___ = 242 A. 180° B. 90°

meriva

Answer:

x =76.45 degrees

Step-by-step explanation:

72 + 252 – 2(7)(25)cos _x__=242

combine like terms

324-350cosx = 242

subtract 324 from each side

-350x = -82

divide by -350

cos x = -82/-350

cos x = 82/350

take the arccos of each side

arccos (cos x) = arccos (82/350)

x =76.45 degrees

I NEED HELP ASAP! : An initial population of 175 quail increases at an annual rate of 22%. Write an exponential function to mode

goblinko [34]

Answer:

About 473 quails.

$P=175(1.22)^t$

Step-by-step explanation:

Exponential equation with $P_0$ as the initial amount and rate of r is:

$P=P_0(1+r)^t$

$P=175(1+.22)^t$

$P=175(1.22)^t$

After 5 years the population will be:

$P=175(1.22)^5$

$P \approx 472.9739$

So the population will be about 473 quails.
