Answer:
a. 12 years
b. 30 years
Step-by-step explanation:
a) Assume Liaqat's age is x. His age would be:
5x + 10 = 70
5x = 70- 10
x = (70 - 10) / 5
x = 12
<em>Liaqat is 12 years old.</em>
b. Assume his uncle's age is y;
4y - 10 = 130
4y = 130 - 10
y = (130 - 10) / 4
y = 30
<em>Liaqat's uncle is 30 years old. </em>

Answer:
Step-by-step explanation:
Given that:
As we know that the Parabola is of type
:
= -4a(y -
) where:
is the origin of the line so we have:
and
<=>
= -4a(y-20)
at y = 0, we have:
= -4a(0-20)
<=>
<=> x = ±
But we know that 2x= 80 <=> x= 40, so:
40 =
<=> 1600 = 80a
<=> a = 20
The equation for the parabola is:
It's height from the center at x= 0 => y= 20
