Step-by-step explanation:

Sum of all interior angles = 900°

A+B+C+D+E+F+G=900

120+B+148+90+142+130+129=900

B=900-759

B=141°

Write an exponential function in the form y=ab^xy=ab x that goes through points (0,8) and (2,288)
timofeeve [1]

Answer:

y = 8•6^x

Step-by-step explanation:

Here, we want to write an exponential equation

To fully write this, we need the values of a and b

From the first coordinates given;

8 = a•b^0

a = 8 since b^0 = 1

Furthermore;

288 = 8•b*2

b^2 = 36

b = √36

b = 6

So we have ;

y = 8•6^x

What is the explicit formula
vova2212 [387]

Answer:

a(n) = 13 - 2n

Step-by-step explanation:

The explicit formula variables are a(n) = a(1) + d (n - 1). The a(1) is your number you started out with, and the d is the common difference. From the recursive formula example, you see that your first number is 11 and your difference is -2.

1. Plug the numbers into the equation : a(n) = 11 - 2 (n - 1)

2. Distribute: a(n) = 11 - 2n + 2

3. Add like terms: a(n) = 13 - 2n

If you want to double check, you can plug 1 into n and see if you get 11. I did this, and I did so it should be correct. Hope this made sense! Have a great day :)

What is the measure of x
mixer [17]

Answer:

x=76 degrees

Step-by-step explanation:

< dij + < jih = 180   straight line

< dij + 107 = 180

subtract 107 from each side

< dij = 73


<jdi + < dij + <idj = 180  triangle

31 + 73 + < idj = 180

combine like terms

104+ < idj = 180

subtract 104 from each side

< idj = 76

<idj = < ajf   vertical angles

76 < ajf

<ajf = x

x=76 degrees
