Answer:
Step-by-step explanation:
**This is a non-linear function and therefore <u>does not have a constant rate of change</u>. It will have a different slope depending on what points you use in the average rate of change formula:
To calculate rate of change, differentiate.
substitute y for 
:
Take natural logs of both sides:
Apply the log rule 
:
Differentiate with respect to 
:
Mulitply both sides by 
:
Replace with 
Therefore, rate of change of the function is :
Answer:
26 + 3 x 42 + 7 x -2 = 138
Step-by-step explanation:
Ok bud, first step we must convert our symbols (Makes it easier to solve)
26 + 3 x 42 + 7 x -2
* subsitutes for multiplication.
I recommend using PEMDAS at times:
1 - Parentheses
2 - Exponents and Roots
3 - Multiplication
4 - Division
5 - Addition
6 - Subtraction
Yet again your numbers were spaced out could they be exponents? if so:
3x^{42}+7x+24
Our answer would round to 24 but he equation was not put in a valid or straight forward way.
Answer:
70
Step-by-step explanation:
28 +24+18
=70
answer is 70
It takes a while to see through this one.
I think that's because the triangle is in a weird position.
The arrows on the two across-lines tell us that those lines are parallel.
And THAT tells us that the two triangles are similar ... the whole big triangle,
and the smaller triangle on the bottom.
If two triangles are similar, then what ?
-- Their corresponding angles are equal. That doesn't help us in this problem.
-- Their corresponding sides are in the same ratio. That helps us a lot !
The left side of the big triangle = 5 + 8 = 13
The left side of the small triangle = 8
Now we know that corresponding sides of the two triangles
have the ratio of 13 to 8 .
The right side of the big triangle = 4 + x
The right side of the small triangle = x
The ratio has to be 13/8 , so ===> (4+x) / x = 13 / 8 .
That's the tough part. Now you take it and finish it off from here.
