Answer:
The correct answers are B and C
Hello,
The parabola having like focus (0,p/2) and as directrix y=-p/2 has as equation x²=2py
Here -p/2=2==>p=-4
x²=-8y is the equation.
Height of the tower = 101.9 m
Solution:
Given data:
Angle θ = 27°
Adjacent side = 200 m
Opposite side = Height
Let height be taken as h.
The given image shows it is a right triangle.
Using basic trigonometric ratio formulas,


The value of tan 27° = 0.5095

Do cross multiplication, we get
0.5095 × 200 = h
101.9 = h
Height of the tower = 101.9 m
Answer:
7, -5, 2/3, 5.79
Step-by-step explanation:
rational numbers are numbers you can put in fraction form.
is not a perfect square, therefore you cannot put it in fraction form.
is an imaginary number. Rational numbers are in the Real Numbers category, so it is not a rational number.
First to find what’s 2x you do 25-11=14, and you know that 7 x 2 =14.
So x= 7.
