Answer:
-15 plus or minus the square root of 65 all over 4 (All over means fraction)
Using translation concepts, it is found that the correct option is:
- reflect across the y-axis, stretch the graph vertically by a factor of 3, shift 2 units up
The parent function is:
- First, the function was <u>multiplied by -1,</u> hence it was reflected across the x-axis.
- Then, it was <u>multiplied by 3</u>, which means that it was stretched vertically by a factor of 3.
- Finally, <u>2 was added to the function</u>, hence, it was shifted 2 units up.
These transformations resulted in the function:

∠TAB = x°
∠TAC = 90°
(Angle between tangent and radius)

∠CAB = a = 90 - x
∠CBA = 90°

Answer:
The angle = 144 degrees.
Step-by-step explanation:
Look at it this way (it is a proportion question)
30 people would require a pie chart made of a full circle (360 degrees)
12 people would require x part of the pie chart.
30/360 = 12 / x Cross multiply
30x = 360 * 12 Simplify the right
30x = 4320 Divide by 30
30x/30 = 4320/20
x = 144 Answer
Answer:
£67.78
Step-by-step explanation:
Bread - 6 x £2.87 = £17.22
Ham - 8 x £6.32 = £50.56
£17.22
+ <u>£50.56</u>
£67.78
