(I) Alpha+Beta= 2
Alpha-Beta= √D/|a|= √10

Alpha^2 - Beta^2
=(Alpha+Beta) (Alpha-Beta)
= 2* √10
= 2√10

How many weeks of flea treatment would Jim’s dog get from one package if each treatment only lasted 3 weeks In a normal year whe

4vir4ik [10]

Solution

Number of weeks in a year = 52 weeks

If in a normal year when each package of flea treatment lasts for 4 weeks, then in a year there Jim's dog will have to be treated for

$\frac{52}{4} =13 times$

Where as, when the fleas are bad in a year, the treatment lasts for only 3 weeks.

Then in a year Jim's dog would get

$\frac{52}{3} =17 times$

So Jim's dog will get 17- 13 =4 treatments more.

4 treatments that are made in 3 weeks each will be 4×3 =12 weeks more treatment

Which of the following graphs could be the graph of the function f(x) = x4 + x3 – x2 – x?

Sav [38]

For this case we have the following function:
$x ^ 4 + x ^ 3 - x ^ 2 - x
$
We can rewrite the function to identify the zeros of it.
When rewriting the function factoring we have: $x (x-1) (x + 1) ^ 2
$
Therefore, the zeros of the function are:
$x = 0

x = 1

x = -1$
Thus, the graph that contains intersections on the x axis in the points mentioned, will be the graph of the function.

See attached image.

Michelle is trying to buy a car that costs $35,550, and she has saved up $20,700. She borrowed the remaining amount that she nee

Dimas [21]

Answer: $ 4,515

Step-by-step explanation:

$\\$ The cost of the car she wanted to buy = $35,550

$\\$ Her savings = $20,700

$\\$ That means she needs( $35,550 - $20,700) more in order for her to buy the car.

$\\$ Amount borrowed from the finance company = $35,550 - $20,700

$\\$ = $ 14,850

$\\$ Since she now owes the financial company a total of $19,365, then the interest accrued by the loan she borrowed is given by:

$\\$ $19,365 - $ 14,850

$\\$ = $4,515

Decimal 0.003 is 1/10 of

Grace [21]

Just multiply the 0.003 by 10 and you'll get the result. The easiest way to multiply such numbers is to move the dot one position to the right (it would be 2 positions if multiplied by 100, 3 by 1000 etc.). You can do the same with dividing, just remember to move to the left then.

So 0.03 is your answer
