​​​​​​​If K = F( A + B ) , find “ A ” if F = 2 , B = 3 , K = 10
Oxana [17]

Answer:

The value of A is 2

Step-by-step explanation:

F = 2 , B = 3 , K = 10

K = F( A + B )

10 = 2(A + 3)

10 = 2A + 6

Now, Subtract 6 from each side we get,

10 - 6 = 2A + 6 - 6

4 = 2A

2A = 4

Now, divide both side by 2 we get,

2A/2 = 4/2

A = 2

Thus, The value of A is 2

<h3><u>FOR V</u><u>ERIFICATION</u><u> ONLY</u> :-</h3>

K = F( A + B )

10 = 2(2 + 3)

10 = 2(5)

10 = 10

L.H.S = R.H.S

Hence Proved!

A man travels 2 miles, turn left and travels 3 miles, turn left again and travel 6 miles. How far is he from the starting point?
Lelu [443]

Answer: 5 miles

Step-by-step explanation:

this creates a polygon which can be shortened to be a triangle with side lengths 3 and 4 and the hypotenuse unknown. to find the side length you use the formula a^2 + b^2 = c^2

3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^2

sqrt(25) = c

c = 5

\boxed { \boxed { a_n = a_1 + d(n - 1)}}

a_{14} = -33 , a_{15} = 9,

a_{14} =  a_1 + d(14 - 1) = -33
a_1 + 13d = -33

a_{15} = a_1 + d(15 - 1) = 9
a_1 + 14d = 9

So the two equations:
a_1 + 13d = -33 ----------------- ( 1 )
a_1 + 14d = 9     ----------------- ( 2 )

(2) - (1) :
d = 42  ----------------- (Sub into 1)

a_1 + 13(42) = -33
a_1 + 546= -33
a_1 = -33 - 546
a_1 = -579

\boxed { \boxed { a_n = -578 + 42(n - 1)}}
