Sine (theta) = 5 / hypotenuse
We do not know the hypotenuse length, so let's use the tangent function.
tan (theta) = 5/7
arc tan (5/7) =  35.538 Degrees

WILL GIVE BRAINLIEST!! 2) Match the graph with its function. Which is an example of growth/decay?
Neporo4naja [7]

The exponential growth is: f(x) = 15*(1.25)^x

And its graph is the first one.

The exponential decay is: f(x) = 250*(0.87)^x

And its graph is the second one.

<h3>How to identify the exponential equations?</h3>

The general exponential equation is of the form:

y = A*(b)^x

Where A is the initial value and b is the base.

  • If b > 1, then we have an exponential growth.
  • if 1 > b > 0, then we have an exponential decay.

Here the two functions are:

f(x) = 250*(0.87)^x

f(x) = 15*(1.25)^x

As you can see, the base for the first one is smaller than 1, then it is an exponential decay (and it has a decreasing graph, so the graph of this one is the second graph).

For the second function, we have the base b = 1.25, which is larger than 1, so it is an exponential growth, and its graph is an increasing graph, which is the first one.

Answer:

x = -\frac{3}{2} or x = 1

Step-by-step explanation:

Using the zero product property, first step is to set the given equation, 2x^2 + x - 1 = 2 , to zero. Then factorise the left side.

Thus,

2x^2 + x - 1 = 2

Subtract 2 from both sides

2x^2 + x - 1 - 2 = 2 - 2

2x^2 + x - 3 = 0

Factorise the left side

2x^2 + 3x - 2x - 3 = 0

x(2x + 3) - 1(2x + 3) = 0

(x - 1)(2x + 3) = 0

Find the solution

x - 1 = 0

Or

2x + 3 = 0

x = 1

Or

2x + 3 = 0

2x = -3

x = -\frac{3}{2}

The answer is: x = 1 or x = -\frac{3}{2}
