I'm assuming the function given is y = 9300(0.991)^x

If so, then the base of the exponent 0.991 is in the form 1+r

1+r = 0.991

r = 0.991-1

r = -0.009

The negative r value indicates a percent decrease.

Specifically it is a 0.9% decrease since 0.009 = 0.9/100 = 0.9%

Any time you have a percent decrease like this, the exponential function is undergoing decay.

Zigmanuir [339]

Answer:

Cosθ = 3/5

Step-by-step explanation:

Given:

In ∆ ABC.

AB measures = 4

BC measures = 5

CA measures = 3

The angle formed at point C is marked theta

angle A is the right angle

Find attached the diagram from the given information.

We are to find the cosine ratio. To do this, we would apply SOHCAHTOA in trigonometry

Sine ratio: Sinθ = opposite /hypotenuse

Cosine ratio: Cosθ = adjacent/hypotenuse

Tangent ratio: Tanθ = opposite/adjacent

From the diagram,

adjacent = AC

hypotenuse = BC

Using the above formula,

Cosθ = adjacent/hypotenuse = AC/BC

Cosθ = 3/5

<span><span>Well, since we know that sin(x) = cos(90-x), we can transform the given into
2x - 8/3 = 90 - (4x - 10/3)
2x - 8/3 = 90 - 4x + 10/3
Now clear fractions by multiplying by three...

6x - 8 = 270 - 12x + 10
6x - 8 = 280 - 12x
18x = 288
x = 16
4x - 10/3 = 4(16) - 10/3 = 64 - 3.33 = 60.67 degrees.
Choice C.</span><span>

Answer:

-2.4

Step-by-step explanation:

Let the unknown number be x.

-3.7 = -1.3(1) + x

-3.7 = -1.3 + x

x - 1.3 = -3.7

x = -3.7 + 1.3

x = -2.4
