Answer:

Step-by-step explanation:

If EG is a diameter, then arc EFG is a semicircle and its measure is 180. Arc FG then is 180 - 124 = 56. Since angle FEG is an inscribed angle and the arc it cuts off is arc FG, then the measure of the inscribed angle is half the measure of the arc it cuts off...so angle FEG is 28 degrees. Keep that in mind; we'll need it in a sec.

If HE is tangent to the circle at E, then angle HEG is a 90 degree angle. Adding that to angle FEG will give you angle FEH. Angle FEH = 90 + 28 = 118

The equation represents both a relation and a function

<h3>How to determine if the equation represents a relation, a function, both a relation and a function, or neither a relation nor a function?</h3>

The equation is given as

y = x^4 - 3x^2 + 4

First, all equations are relations.

This means that the equation y = x^4 - 3x^2 + 4 is a relation

Next, the above equation is an even function.

This is so because

f(x) = f(-x) = x^4 - 3x^2 + 4

This means that the equation is also a relation

Hence, the equation represents both a relation and a function

hali invested money into an account that is guaranteed to grow$28 each year. she graphs a line that represents the growth of the
tankabanditka [31]
If we take the graph with x as number of years and y as amount of dollars in it as mentioned in the equation;
gradient of the graph/ slope (m) = Change in y / change in x 
so if we take a certain portion of the graph 
x is the number of years, since we know the growth for one year,
lets take change in x as 1 year
y is amount of dollars, the change in amount of dollars for one year is 28
therefore change in y is 28
m(slope) = 28(change in y) / 1 (change in x)
              = 28

Answer:

(-2,-5)

Step-by-step explanation:

Because his house is in the same quadrant as the city park (quadrant 3) the answer's coordinates will have x=a negative number and y= a negative number. So, the answer will be (-2,-5).

Hope this helps!
