What is the third term of the sequence defined by the recursive rule f(1)=3 f(n)=f(n-1)+4
Need f(2):
f(2)=f(2-1)+4
f(2)=f(1)+4
f(2)=(3)+4=7
FIND f(3):
f(3)=f(3-1)+4
f(3)=f(2)+4
f(3)=(7)+4
f(3)=11
Answer:
x=8
z = 115
Step-by-step explanation:
65 and 13x - 39 are vertical angles so they are equal
65 = 13x - 39
Add 39 to each side
65+39 = 13x - 39+39
104 = 13x
Divide each side by 13
104/13 = 13x/13
8 =x
65 and z are supplementary angles because they form a straight line. This means they add to 180
65+z = 180
Subtract 65 from each side
65+z-65 = 180-65
z = 115
Answer:

Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:

We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:


Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side

and we simplify:


now it's easy to solve for t:

And thus we arrive to the solution.
