1/10 of 32 million is 3.2 million.
Because
1/10 x 32,000,000 = 3,200,000
-22+(x/35)=-25
add 22 to both sides
x/35=-3
multiply both sides by 35 to cleaf raction
x=-105
number was -105
The cost of old computer is $ 357
<em><u>Solution:</u></em>
Let "x" be the cost of old computer
From given,
Cost of new computer = $ 709
Blairs new computer cost 5$ less than twice the cost of her old computer
Therefore,
Cost of new computer = twice the cost of old computer - 5
Cost of new computer = 2x - 5
709 = 2x - 5
2x = 709 + 5
2x = 714
Divide both sides by 2
x = 357
Thus the cost of old computer is $ 357
Answer:
5/49
Step-by-step explanation:
3/7 x 5/21=15/147=5/49
Answer:
The approximation by Taylor series of f'(3) is 9.5000.
Step-by-step explanation:
Taking the two first terms for Taylor series gives the following expression:

Where e represents the error of the approximation and in this case is of second order. For this particular example, it is no required to calculate.
Note that in the equation x is the independent variable, in contrast, xo is the value where all the derivatives of the function are calculated and must be defined. Observe that the value for the first derivative in x equal 3 is wanted to know, so xo will be equal 3.
Now to find f'(3) will use the rest of the information that was given:
f(5)=28 (x=5)
Replacing the previous values in the Taylor expansion:


Solving the equation:



There was no rounding in the calculated value.
