Formula for a octagon:
2(1+ \sqrt{2} ) a^{2}
a = 16.35
2(1+ \sqrt{2} ) 16.35^{2} =1290.75
Area = 1290.75

Given the function k(t)=2t−1: a. Evaluate k(2). b. Solve(k)=7.
Aleksandr-060686 [28]

Answer:

k(2) = 3

t = 4

Step-by-step explanation:

Given

k(t) = 2t - 1

Solving (1): k(2)

Take t as 2 such that t = 2

This gives

k(2) = 2 * 2 - 1

k(2) = 4 - 1

k(2) = 3

Solving (2): k(t) = 7

Substitute 7 for k(t)

7 = 2t - 1

Add 1 to both sides

7 + 1 = 2t - 1 + 1

2t = 8

Divide both sides by 2

t = \frac{8}{2}

t = 4

What is:<br> k–66≤ – 84<br> in one-step inequalities?
kykrilka [37]

Answer:

k\le \:-18

Step-by-step explanation:

First, you add 66 to both sides so then the equation you are trying to solve will be: k-66+66\le \:-84+66

Finally, you simplify and get: k\le \:-18

Hope this helped!

A light aircraft travels 5 miles per hour less than twice the speed of a bus. If the bus can travel 114 miles in the same time i
Rufina [12.5K]
A represents the speed of the aircraft.
b represents the speed of the bus.

a=2b-5
114/b=218/a

Substitution method

114/b=218/(2b-5)

(2b-5)*(114/b)= 218

(228b-570)/b = 218

228b-570= 218b

228b-218b=570

10b= 570

b=57

Plug the value of b into one of the original equations.

a=2(57)-5
a=114-5
a=109

Final answer:
Average speed of plane= 109
Average speed of bus= 57
