Answer:
<h2>a) |-13 - (-4)|</h2>
Step-by-step explanation:
The formula of a distance between two points (numbers) A and B on the number line:
d = |B - A| = |A - B|
We have A = -13 and B = -4. Substitute:
d = |-13 - (-4)|
Answer: 101.956
Step-by-step explanation:7.18•14.2= 101.956
Answer: see below
<u>Step-by-step explanation:</u>
I used a coordinate graph and placed the Ticket Booth at the origin (0, 0)
Then I chose a distance of 4 (you can choose any distance) and placed the three events equidistant from the origin by using the x- and y- axis to easily determine a distance of 4 from the origin.
(0 - 4, 0) = (-4, 0)
(0 + 4, 0) = (4, 0)
(0, 0 + 4) = (0, 4)
If the booths are placed first you would need to find the equation of a circle that contains all three points and place the booth at the center.
You do this by creating a system of three equations inputting the x,y coordinates of each booth and solving for h, k, r.
Equation of a circle is: (x - h)² + (y - k)² = r²
Answer:
12z
Step-by-step explanation:
f=(x) = 4+3z and g(x)= x^2-3.
f= (x)7z
g(x) = x^ 2-3
g(x) =1
(f-g) (2)
7z- 1 (2)
6z ×2
12 z
