Answer:

Step-by-step explanation:
Use the Law of sines to find y in ∆WXY, given:
m < Y = 106°
m < X = 58°
WY = x = 8
WX = y = ?
Therefore,


Multiply both sides by 0.961 to solve for y

Answer:
Step-by-step explanation:
Parent function has been given as,
f(x) = x²
If the parent function is reflected across x-axis,
g(x) = -f(x)
= -x²
Further this function is vertically stretched by 2 units then the new function will be,
e(x) = -2x²
Therefore, parent function 'f' is reflected across x-axis and vertically stretched by scale factor of 2.
Answer:
19,500 people
Step-by-step explanation:
20% of 25,000 is 5,000.
Add 5,000 to 25,000 - this will give you 30,000. That is a 20% increase.
65% of 30,000 is 19,500, thus there are 19,500 people in the stadium.
Answer:
B. 15 cm
Step-by-step explanation:
Hypotenuse (h) = 17 cm
perpendicular (p) = 8 cm
base (b) = YZ = ?
We know that by using Pythagoras theorem
b = √ (h² - p²)
= √ ( 17² - 8²)
= √225
= 15 cm
YZ = 15 cm
