F(x)=2^x evaluate f(5)
Helen [10]

Hey there!

To solve this, we will first replace x with 5 anytime we see it in the equation.

f(5) = 2^5

Now, we simplify 2^5.

The base is 2 and the exponent is 5 in this case.

The exponent is the number of times you multiply the base by itself. In oour case:

2 x 2 x 2 x 2 x 2 = 32

f(5) = 32

Hope this helps!

Please help!! i have no idea!
Gemiola [76]

Answer:

θ = 60.34

Step-by-step explanation:

\frac{\left(12.8\cdot \:sin\left(90\right)\right)}{sin\left(52.3\right)} = 16.177

\frac{\left(16.177\cdot \:sin\left(90\right)\right)}{18.6} =  θ = .869

arcsin\left(.869\right) = 60.34

Please help need to get to 80%
Shalnov [3]

Answer:

\frac{1}{6}

Step-by-step explanation:

First, start by converting 4 feet to inches. Note that 1 foot = 12 inches.

Set up a unit converter:

4\ ft(\frac{12\ in}{1\ ft})

The ft cancel out leaving us with:

4*12\ in=48\ in

Now, we can set up a scale factor...

\frac{drawing}{real\ length}=\frac{8}{48}=\frac{1}{6}

The graph below shows the solution to a system of inequalitie
Reptile [31]
Given the graph, we need to look for the equation of the line using the linear equation since the plot is obviously a line.

To do that, we need two points. The simplest points to locate are the two points that converges the x and y axes which are (3,0) and (4,0), respectively. Now we apply the linear equation formulation:

y = mx+b

First, we need to get the slope.

m = (y2-y1)/(x2-x1)
m = (4-0)/(0-3)
m = -4/3

Since we know the slope, we need to look for the b which is also the y-intercept or the point at which x = 0.

So at x = 0, which point or value at y-axis hits with the line? It is the point (0,4).
Therefore, b = 4.

Completing the equation,

y = -(4/3)x + 4

or we can write it as

4x + 3y = 12.

Now to know which of the choices is correct, we simply assign values and see for ourselves which is true.

Let x = 2, so y = 2

4(2) + 3y = 12
8 < 12

If you assign more values, you will notice that 4x + 3y is always less than or equal to 12. Thus, the answer is letter a.
