Answer:

y = 28, x = 28

Step-by-step explanation:

Step 1: Find y

Since 62 + y is a right angle, they add up to 90

62 + y - 62 = 90 - 62

y = 28

Step 2: Find x

Since 62 + x is a right angle, they add up to 90

62 + x - 62 = 90 - 62

x = 28

Answer: y = 28, x = 28

The nth term can be expressed as 16n-70.
So, if we solve
122=16n-70
we find n=12.
Thus, 122 is the 12th term in the sequence.

A formula is expressed as d=a(2+kt). Express k in terms of d, a and t

taurus [48]

Answer:
k = $\frac{d-2a}{at} = \frac{d}{at} - \frac{2a}{at} = \frac{d}{at} - \frac{2}{t}$ 

Explanation:
To get the value of k, we will need to isolate it on one side of the equation.
This can be done as follows:
d = a(2+kt)

1- get rid of the brackets using distributive property:
d = a(2+kt)
d = 2a + akt

2- Subtract 2a from both sides of the equation:
d - 2a = 2a + akt - 2a
d - 2a = akt

3- Divide both sides of the equation by "at":
 $\frac{d-2a}{at} = \frac{akt}{at}$ 

 $k= \frac{d-2a}{at}$

4- We can further simplify the answer as follows:
k = $\frac{d-2a}{at} = \frac{d}{at} - \frac{2a}{at} = \frac{d}{at} - \frac{2}{t}$

Hope this helps :)
