Which equation shows a correct relation for triangle RSQ?

Mathematics
1 answer:
son4ous [18]2 years ago
4 0

Answer:

sinQ=cosR

Step-by-step explanation:

First we need to find out the measure of ∠R.

The sum of all the angles in a triangle add up to 180. Therefore:

∠Q+∠R+∠S=180

66+∠R+90=180

∠R=180-156

∠R=24°

Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.

sinQ=cosR

sin66=cos24

0.9135454576=0.9135454576

So the second equation is the correct relation.

Naddik [55]

Answer: He was killed 24.83 hours before the body was found.

Step-by-step explanation:

Since we have given that

T=T_0+(T_1-T_0)(0.97)^t

Here, T is the temperature of a body t hr after death, T = 82°F

T₀  is the air temperature , T₀ = 67°F

T₁ is the body temperature at the time of death = T₁ = 98.6°F

So, we will substitute all the values in the above equation.

82=67+(98.6-67)(0.97)^t\\\\82-67=31.6(0.97)^t\\\\\dfrac{15}{31.6}=(0.97)^t\\\\0.474683544=(0.97)^t\\\\\text{Taking ln on both sides}\\\\\ln(0.474683544)=t\ln(0.97)\\\\-0.745=t\times -0.030\\\\t=\dfrac{0.745}{0.030}\\\\t=24.83\ hours

Hence, he was killed 24.83 hours before the body was found.

VladimirAG [237]
Well, just solve the equation

-70 = a(0-6)^2+2
-70 = a(-6)^2+2
-70 - 2 = 36a
a = -72/36 = -2

Multiplication and division are inverse operations.
If you start with a number and divide it and multiply it by the same number (not zero), you get the original number back.

Since you want to undo a division by 7, you must multiply by 7.
