Answer:
No it is not a function
Step-by-step explanation:
Since x=0 produces y=4 and y=0, the relation (2,3),(0,4),(−1,2),(3,−4),(0,0),(-3,−2),(−2,0) is not a function.
Answer:
-6 2/3
Step-by-step explanation:
The angle of elevation that the instruments have to record to be at the correct height is given as 79°
<h3>How to solve for the angle of elevation</h3>
We have 2x + 70 = 180
We have to find the value of x
2x = 110
x = 55
y/sin x = 225/sin70
This is the use of sine rule
From here we would have
y = 225(sinx/sin70)
Remember x = 55
y = 225(sin55/sin70)
y = 196.1378
tanθ = 1000/y
tan θ = 1000/196.1378
tanθ = 5.098
θ = tan⁻¹5.098
= 78.90°
Hence the conclusion is that the angle of elevation has to be 78.9 degrees for it to be at the correct height.

Complete question :
The spinner shown is spun once. Determine the probability of each event. Express each answer as a fraction, a decimal, and a percent. P(C)
Answer:
1 / 8; 0.125 ; 12.5%
Step-by-step explanation:
From the spinner :
The number of partitions or faces on the spinner is 8 ;
The number of occurences of c on the spinner is 1
The probability of obtaining c written as P(c) :
Probability = required outcome = number of c on spinner / total possible outcomes, total number of faces in spinner = 8
P(c) = 1 / 8
As decimal :
1/8 = 0.125
As a percentage :
0.125 * 100% = 12.5%
