<u>Answer</u>
Part 1: l = -1.665g
Part 2: Max-mum the spring can support.
Part 3: The spring constant.
<u>Explanation</u>
Gradient is also called the slope.
Slope = (change in y) /(change in x)
= (60 -40)/(6.7 - 40)
= 20 / -33.3
= - 0.600600601
Since the graph is a straight line, the equation would be,
m ∝ l
m = kl Where K is the constant.
<u>g</u> = -0.60l
l = -1.665g
<u>Part 2</u>
The Y-intercept represent the mix-mum weight the spring can support.
<u>part 3</u>
The slope in this case represent the spring constant.
Answer:
-x^3-5x^2+10x-4
Step-by-step explanation:
(−x + 1) (x ^ 2 + 6x − 4) = (-x)(x ^ 2 + 6x − 4) + 1(x ^ 2 + 6x − 4)
= -x^3-6x^2+4x+x^2+6x-4 = -x^3-5x^2+10x-4
Step-by-step explanation:
f(x) = —x^2 – 3x
f(10)={-10}²-3×10=100-30=70
Answer:
m∠2= 180-30=150
m∠3= 30
m∠4=30
m∠5=150
m∠6=150
m∠7=30
Step-by-step explanation:
since these are angles of parallel lines cut by a transversal the theorems of vertical, corresponding, supplementary, and complementary angles apply.
