Answer:

$0.1 per pound stone

Step-by-step explanation:

If Juanita wants to buy 12.5 pounds of stone and a pound of stone is $1.80 She will have to pay:

=12.5*1.80=22.5

Juanita will be paying $22.5 for 12.5 pounds of stone.

If the salesman offers her a total price of $21.25, we can determine how much she is paying per pound of stone as:

21.25/12.5=1.7

Juanita will be saving:

1.8-1.7=0.1

She will be saving $0.1 per pound and $1.25 in total

Verify by direct substitution that the given power series is a solution of the indicated differential equation. [Hint: For a pow
shepuryov [24]

Answer:

The given power series y =\sum^{\infty}_{n=0} {(-1)^n x^{2n}} is a solution of the differential equation (1+x^2)y' + 2xy = 0

Step-by-step explanation:

This is a very trivial exercise, follow the steps below for the solution:

Step 1: Since n = 0, 1, 2, 3, 4, ........, Substitute the values of n into equation (1) below.

y =\sum^{\infty}_{n=0} {(-1)^n x^{2n}}.....................(1)

y = 1 - x^2 + x^4 - x^6 + x^8.........

Step 2: Find the derivative of y, i.e. y'

y' = -2x + 4x^3 - 6x^5 + 8x^7 .............

Step 3: Substitute y and y' into equation (2) below:

(1+x^2)y' + 2xy = 0\\\\(1+x^2)(-2x + 4x^3 - 6x^5 + 8x^7......) + 2x(1 - x^2 + x^4 - x^6 + x^8.......) = 0\\\\-2x+ 4x^3 - 6x^5 + 8x^7........ - 2x^3 +4x^5 - 6x^7 + 8x^9 ......+ 2x - 2x^3 + 2x^5 - 2x^7 + 2x^9...... = 0\\\\0 = 0

(Verified)

Since the LHS = RHS = 0, the given power series y =\sum^{\infty}_{n=0} {(-1)^n x^{2n}} is a solution of the differential equation (1+x^2)y' + 2xy = 0

The difference of two positive numbers is 69. The quotient obtained on dividing one by the other is 4. Find the number.​
valentinak56 [21]

Answer:

x=92 y=23

Step-by-step explanation:

Let them be x and y respectively

so given

x-y=69

and

x/y=4  x=4y

so we can write

x-y=69

as

4y-y=69  3y=69 y= 69/3 = 23

now y is 23

so putting in any equation will give the value of x

so

x-23=69 x=92

If you have 3/12 of an orange, how many fourths do you have?​
Mrac [35]

Answer:

Answer: one fourth

Fourth is a word that used to describe a number value of 1/4. To answer this question, you need to change the number you got (3/12) into x/4 form. To convert 12 into 4, then you need to divide the numerator and denominator with 3. The equation would be (3/3)/(12/3)= 1/4. 

To determine how much fourth the number has, you need to divide the result with 1/4. The calculation would be: (1/4)/ (1/4)= one fourth

hope its help

thank you

good day
