 Find 5 consecutive whole numbers if it is known that the sum of the squares of the first 3 numbers is equal to the sum of the squares of the last 2 numbers.

Answers

so... our numbers... let's say the first one is hmmm "a"
so the second and subsequent are
a
a+1
a+2
a+3
a+4

there, 5 consecutive whole numbers or integers for that matter

now, we know the sum of the square of the first three,
is the same as the sum of the square of the last two

so \bf \begin{cases}a\na+1\na+2\n\textendash\textendash\textendash\textendash\na+3\na+4\end{cases}\qquad (a)^2+(a+1)^2+(a+2)^2=(a+3)^2+(a+4)^2

do a binomial theorem expansion on those, solve for "a"

2. From the definition of the derivative (definition 5.3), find the derivative for each of the following functions: (a) f(x) = 6x (b) f(x) = 12x – 2 (c) f(x) = kx² for k a constant

Answers

Answer:

a) f'(x)=6

b) f'(x)=12

c) f'(x)=2kx

Step-by-step explanation:

To find :  From the definition of the derivative find the derivative for each of the following functions ?

Solution :

Definition of the derivative is

f'(x)= \lim_(h \to 0)((f(x+h)-f(x))/(h))

Applying in the functions,

a)f(x)=6x

f'(x)= \lim_(h \to 0)((6(x+h)-6x)/(h))

f'(x)= \lim_(h \to 0)((6x+6h-6x)/(h))

f'(x)= \lim_(h \to 0)((6h)/(h))

f'(x)=6

b) f(x)=12x-2

f'(x)= \lim_(h \to 0)((12(x+h)-2-(12x-2))/(h))

f'(x)= \lim_(h \to 0)((12x+12h-2-12x+2)/(h))

f'(x)= \lim_(h \to 0)((12h)/(h))

f'(x)=12

c) f(x)=kx^2 for k a constant

f'(x)= \lim_(h \to 0)((k(x+h)^2-kx^2)/(h))

f'(x)= \lim_(h \to 0)((k(x^2+h^2+2xh-kx^2))/(h))

f'(x)= \lim_(h \to 0)((kx^2+kh^2+2kxh-kx^2)/(h))

f'(x)= \lim_(h \to 0)((h(kh+2kx))/(h))

f'(x)= \lim_(h \to 0)(kh+2kx)

f'(x)=2kx

A mother wants to invest $6000 for her children's education. She invests a portion of the money in a bank certificate of deposit (CD account) which earns 4% and the remainder in a savings bond that earns 7%. If the total interest earned after one year is $360, how much money was invested at each rate?

Answers

0.04x+0.07(6000-x)=360
0.04x+420-0.07x=360
0.04x-0.07x=360-420
−0.03x=−60
X=60/0.03=2,000 at 4%
6000-2000=4000 at 7%
