Answer:
a. 12 minutes
b. 34 minutes
Step-by-step explanation:
Here, we are told that Ima has driven 5 minutes before Polly started driving
So if Ima has driven for x minutes , polly would have driven for y minutes but the difference between x and y is 5
So mathematically;
x = y + 5
a. 17 = y + 5
y = 17-5 = 12 minutes
b. x = 29 + 5
x = 34 minutes
For the given points to lie on the parabola,
a = -3 and k = 10.
An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively. It's also crucial to remember that the fixed point is not located on the fixed line. A parabola is a locus of any point that is equally distant from a given point (focus) and a certain line (directrix).
According to the question,
Equation of parabola : y = a
+ k
Points A(1,7) and B(4,-2)
For the points to lie on the parabola,
7 = a
+k
7 = a + k
Similarly,
-2 = a
+ k
-2 = 4a + k
On solving the two equations simultaneously, we get,
a = -3
k = 10

We simply divide the mass of Saturn with the mass of Earth.
5.686 x 10^26 / 6.04 x 10^21
The rule of significant figures when dividing numbers is that the least amount significant figures must be used in the quotient.
Therefore, Saturn is 9.41 x 10^4 times heavier than Earth.
