Answer:138
Step-by-step explanation:
Cost of a canoe is $12 and call number of days rented two mountain bikes are $18 and call number of days rented. That sum has to be < $138 (it should be less than or equal to $138, but that isn't a choice).12c+18m<$138C.
Answer:
a) Josef jogging from A to B;
i. speed = 2 m/s
ii. velocity = 2m/s
a) a) Josef jogging from A to C;
speed = 1.9 m/s
ii. velocity = 2.2 m/s
Step-by-step explanation:
One major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.
a) Josef jogging from A to B;
distance = 300 m
time = 2.5 seconds = 150 seconds
i. his average speed =
=
= 2 m/s
ii. his average velocity =
=
= 2 m/s
b) Josef jogging from A to C,
distance = 300 + 100 = 400 m
time = 2.5 + 1 = 3.5 minutes
= 210 seconds
i. his average speed =
=
= 1.9 m/s
ii. his average velocity =
= 4 m/s
= 1.9 m/s
his average velocity =
= 2.2 m/s
Recall that (a + b)² = a² + 2ab + b².
Let a = x² and b = y². Then
(x² + y²)² = (x²)² + 2x²y² + (y²)²
⇒ x⁴ + y⁴ = (x² + y²)² - 2 (xy)²
Given that x² + y² = 13 and xy = 6, we have
x⁴ + y⁴ = 13² - 2×6² = 97
94 it is it is it s is isisisisisisisisisisissisisiiss it is 94
4-9x+14x>32 do the exponents
5x>28 combine terms and subtract 4 from both sides
x>5 3/5 divide by 5 on both sides
