Answer:
A) 32 kg/m
B) 48 kg/m
C) 72 kg/m
Step-by-step explanation:
We are given mass is; m = 4x²
Linear density is the derivative of mass with respect to the position x. So linear density is;
ρ = dm/dx
Differentiating 4x²,we have; ρ = 8x
A)at x = 4; ρ = 8(4) = 32 kg/m
B) at x = 6; ρ = 8(6) = 48 kg/m
C) at x = 9; ρ = 8(9) = 72 kg/m
Step-by-step explanation:
First, find the slope between the points.
m = (y₂ − y₁) / (x₂ − x₁)
m = (24 − 17) / (20 − 15)
m = 7/5
Next, write the equation in point-slope form, using either of the points.
y − 17 = 7/5 (x − 15)
If desired, simplify.
y − 17 = 7/5 x − 21
y = 7/5 x − 4
Answer:
she get paid for 192 dollars for 4 hours
1. -1/5>-3/5 because we have like denominators we compare the inputs by the numerators.
2. 3/4 > 5/8 the least common denominator is: 8
Rewriting as equivalent fractions with the LCD:
3/4 = 6/8 5/8 = 5/8
Comparing the numerators of the equivalent fractions we have:
6/8 > 5/8
