I can help you, as long as it's something I've already learned so as long as it anything less than stats. I'll pm you.
Answer:
y = 3
Step-by-step explanation:
The vertex of the parabola is (1,4) and the axis of the parabola is parallel to the positive y-axis.
So, the equation of the parabola will be (x - 1)² = 4a(y - 4) ....... (1)
Now, we have to get the value of a since the equation id the directrix is y = 4 - a.
Now, the parabola passes through the point (3,5) {Obtained from the graph).
Therefore, from equation (1), we get, 2² = 4a × 1, ⇒a = 1
Therefore, the equation of the directrix is y = 4 - 1 = 3. (Answer)
1/7
This is because there are 7 members and each person gets 1/4
Answer:
The answer is a = 4.5
Step-by-step explanation:
To find this we start by dividing away the coefficient of a.
10a = 45 ----> Divide both by 10
a = 4.5
Answer:
Total = 30.75cm squared
Step-by-step explanation:
Area of trapezium = (A+b)h divided by 2 = 15cm squared
area of triangle 1 = 1/2 x b x h = 3 cm squared
Area of triangle 2 = 2.25 cm squared
Area of trapezium at the bottom = 10.5 cm squared
Total = 30.75cm squared
Hope it helped
