i.
j.
<u>Neither:</u>
f.
h.
<u>Linear:</u>
b.
d.
g.
Step-by-step explanation:
Linear equations are generally expressed in the form y = mx + b - the highest exponent of x is one.
Quadratics are expressed as y = ax^2 + bx + c - the highest exponent of x is two.
Any equation with an exponent of x higher than two is neither linear nor quadratic, but instead cubic or higher. Therefore we can simply sort these equations by the highest exponent of x present after simplifying.
Answer:
1. X= 25.9 meters
2.X= 21.3 meters
Step-by-step explanation:
1. Tan 50°= X/21
2. Tan 12°= X/100
In its simplest form the domain is all the values that go into a function, and a range is all the values that come out.
Answer:
radius = 65 cm
Step-by-step explanation:
(See image attached for better comprehension)
To find the value of the radius, we just need to draw a triangle, where one side is half of the chord (the distance from the chord to the center creates a point that divides the chord in two equal segments), other side is the distance from the chord to the center, and the hypotenusa will be the radius.
So, using Pythagoras' theorem, we have that:
r^2 = 56^2 + 33^2
r^2 = 4225
r = 65 cm
First, we need to turn this into an improper fraction. Therefore we have: 1 1/4 = 5/4 and 4 3/4 = 19/4
Now we multiply across and eliminate as needed.
5/4 * 19/4 = 95/16
Finally, we reduce and convert to a mixed fraction.
16 goes into 95, 5 times with a remainder of 15. Therefore, we can conclude that our answer is: 5 15/16.
