Answer:
m = 55t
t = m/55
Step-by-step explanation:
According to the formula for calculating speed expressed as;
Speed = distance/time
Given;
Distance = 55mph
required:
distance as a function of t
time as a function of distance m
If distance is m and time is t
From the formula;
55 = m/t
m = 55t
Hence the equation to solve for miles m is m = 55t
To get t, we will cross multiply from 55 = m/t;
55t = m
Divide both sides by 55
55t/55 = m/55
t = m/55
Hence the equation to solve for time in hours is t = m/55
Answer: 8.4 miles
Step-by-step explanation:
d = rt
Solve for her rate
21 = 5r
r = 21/5
r = 4.2
Solve for if the time is 2 hours and rate (solved previously) is 4.2
d = 4.2*2
d = 8.4
Answer:
TOP 2, and bottom right
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
In a geometric sequence there is a common ratio. The common ratio is the number that when multiplied by a number in the sequence gives you the next number. To find the common ratio, you divide any number by the previous number. Every division must give you the same answer, the common ratio.
Now try to find the common ratio of this sequence.
36/12 = 3
12/3 = 4
The ratios between terms are not equal. There is no common ratio.
Therefore, this sequence is not a geometric sequence.
Answer: b) (2m³ - 4p⁵)(2m³ + 4p⁵)
<u>Step-by-step explanation:</u>
Use the difference of a square formula: a² - b² = (a - b)(a + b)
(2m³)² - (4p⁵)² = (2m³ - 4p⁵)(2m³ + 4p⁵)
