Answer:
= + 2
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 5 - 3 = 7 - 5 = 9 - 7 = 11 - 9 = 2
A recursive formula allows a term in the sequence be found by adding d to the previous term, then
= + 2 : with a₁ = 3
The average speed is 97346 feet per hour approximately
<em><u>Solution:</u></em>
Given that blue whale calf swam from Miami, Florida, to Havana, Cuba, a distance of 228 miles, in 12 hours 22 minutes
To find: average rate of speed in feet per hour
<u><em>The speed is given by formula:</em></u>
From given information,
We know that,
Therefore,
Substituting the values in above formula,
Thus average speed is 18.4366 miles per hour
<em><u>Let us convert to feet per hour</u></em>
We know that,
1 mile = 5280 feet
Therefore,
18.4366 miles = 18.4366 x 5280 feet = 97345.248 feet
Thus average speed is 97346 feet per hour approximately
Answer:3y-3y=0
Step-by-step explanation: They are giving you a value for X that is 3y. You put that value in place of x. So, if x=12 and they want you to substitute for x-3y=0, you would have 12-3y=0....but the value of x in your question is 3y....so you replace the x in the equation with it's value...which is given to you as 3y....or in my example, 12.
3y(-5y^3+4y-3)
Hope this helps
Answer:
t = 9.57
Step-by-step explanation:
We can use trig functions to solve for the t
Recall the 3 main trig ratios
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent.
( note hypotenuse = longest side , opposite = side opposite of angle and adjacent = other side )
We are given an angle as well as its opposite side length ( which has a measure of 18 ) and we need to find its adjacent "t"
When dealing with the opposite and adjacent we use trig ratio tan.
Tan = opp / adj
angle measure = 62 , opposite side length = 18 and adjacent = t
Tan(62) = 18/t
we now solve for t
Tan(62) = 18/t
multiply both sides by t
Tan(62)t = 18
divide both sides by tan(62)
t = 18/tan(62)
t = 9.57
And we are done!
