Answer:

777.9 meters

Step-by-step explanation:

From the given figure the angle adjacent to 40 degree is 50 degree

because it forms a right angle triangle (90 degree)

Now we use trigonometric ratio to find out the hypotenuse x

cos = adjacent side / hypotenuse

cos(50)= \frac{adjacent}{hypotenuse}

cos(50)= \frac{500}{x}

Cross multiply it

x= \frac{500}{cos(500)}

x=777.8619

So x= 777.9 meters

Answer:

777.9 meters

Step-by-step explanation:

Notice that the angles of the right triangle are 40 and 50 degrees, with the 500 meter side adjacent to the 50 degree angle. Now, we can set up an equation: cos (50 degrees) = 500 / x. Use a calculator to find that the answer is 777.9.

Answer:

30°

Step-by-step explanation:

the three interior angles of a triangle add up to 180, so 60° + 90°+ 30° just works. Sorry it's such a bad explanation, but the answer works . I have acellus too and I entered the answer before answering your question.

Which equation represents exponential decay? * a y=3^x-4 b y=2(4)^x c y=1/2(3)^x d: y=6(1/3)^x
yuradex [85]

The equation which represents exponential decay is y=6(1/3)^{x}

Given four equations : 1)y=3^{x} -4, 2) y=2(4)^{x}, 3) y=3^{x}/2, 4) y=6(1/3)^{x}.

Equation is relationship between two or more variables expressed in equal to form. Equations of two variables look like ax+by=c. Exponential equation look like a^{x}.

Decay means when x value increases ,the y value decreases.

We haveto put 3 values for x in the equations to check.

1)y=3^{x} -4

put x=0,y=-3

put x=1, y=-1

put x=2, y=5

No,itdoes not represents exponential decay.

2) y=24^{x}

put x=0,y=2

put x=1, y=8

put x=2, y=32

No,it does not represents exponential decay.

3) y=3^{x}/2

put x=0,y=0.5

put x=1, y=1.5

put x=2, y=4.5

No,it does not represents exponential decay.

4)y=6(1/3)^{x}

put x=0,y=6

put x=1, y=2

put x=2, y=0.67

Yes ,it represents exponential decay.

Hence the equation which represents exponential decay is y=6(1/3)^{x}.
