Answer:
43.60°
Step-by-step explanation:
We can solve the triangle using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering triangle ΔDEF, where ∠F=90°, FE = 21, DF = 20, and ED = 29
As such, with respect to angle E, ED is the hypotenuse, DF is the opposite side and FE is the adjacent side
Cosine ∠E = 21/29
∠E = cos-1 0.724137931
∠E = 43.60° to the nearest hundredth
14 over 4509 would be an equvilent fraction
For the given logarithmic function, we have:
domain: (4, ∞).
range: (-∞, ∞).
<h3>
How to determine the domain and range of the function?</h3>
For a function y = f(x), the domain is the set of the possible input values, and the range is the set of the possible output values.
Here we have the function:
f(x) = log(x - 4) - 3
First, we know that the range of logarithmic functions is the set of all real numbers.
We also know that the argument of logarithmic functions can only be larger than zero.
So the domain is defined by x > 4.
Then we have:
domain: (4, ∞).
range: (-∞, ∞).

Answer:
Step-by-step explanation:
This is called a 'System of equations'.
Say that you have these two expressions, and the unknown is "b".
5b = y
4b+2 = y
Now we can solve two ways; graph it or solve it.
Solving it, we can see that they both equal y, so:
5b=4b+2
move 4b to the left side by subtraction:
(5b-4b) =2
b = 2
let's see what y equals when b = 2
5 * 2 = y
10 = y
Graphing it we see they intersect, or solve at
(2,10) or b=2, y=10
Hope this helps!
