Answer:
B(12)
Step-by-step explanation:
Constant of proportionality is basically the slope.
Slope = Δy/Δx
here y= distance travelled and x= number of hours
so slope = 36-3/3-0.25= 33/2.75 = 12
Answer:
294.13467
Step-by-step explanation:
73 (3) = 219
6.13467
+ 69.00000
219.00000
= 294.13467
Inequalities differ from equations mainly because of the signs. Inequalities have signs such as < or >, rather than =, which is used for equations. A real life scenario could be for number lines, which inequalities are used for.
Answer:
21, 24, 29
5
Step-by-step explanation:
The first term is when n = 1.
(1)² + 20 = 21
The second term is when n = 2.
(2)² + 20 = 24
The third term is when n = 3.
(3)² + 20 = 29
To find how many terms are less than 50, set n² + 20 equal to 50 and solve for n:
n² + 20 = 50
n² = 30
n ≈ 5.477
Rounding down, n = 5 is the last term that is less than 50.
Therefore, there are 5 terms in the sequence that are less than 50.
