Part A: Equation 1: 20x +120
Equation 2: 25x +80
( I think this is the answer)
Part B:
Walking down a hill then running down the hill. The direction of the line doesn't matter, it's the pace that you're going. The line is moving at a constant speed and then gets steeper which means the person would be going faster
Answer:
(a)
(b)
(c)Using Linear Approximation,L(4.2)=137.6
Using Quadratic Approximation,
Step-by-step explanation:
Given:
(a)Linear Approximation,
(b)Quadratic Approximation,
(c)To approximate:
L(x)=48x-64
L(4.2)=48(4.2)-64=137.6
Also, Using Quadratic Approximation
Answer:
5.946 cm
Step-by-step explanation:
Using the Pythagorean Theorem, we know that in a right angle triangle to find the longest side we must use the equation a^2 = b^2 + c^2
A is the longest side while b and c are the other two sides
To find one side we must use
b^2 = a^2 - c^2
a squared = 6.9 squared - 3.5 squared
a^2 = 35.36
square root 35.36 to get a
a = 5.946427499
a (3 d.p.) = 5.946
