the length of the garden should be 15 feet longer than its width and the area is less than 100 ft^2

Answers

Answer:

If the perimeter is 200feet (two lengths and two widths) then one width+one length equals 100feet.

If the length is 10 feet longer than the width, then length = 55 feet, and width =45 feet

Therefore the area of the rectangle is 45x55 feet, which equals 2475 sq.ft

Ast year, Saleh opened an investment account with $8600. At the end of the year, the amount in the account had decreased by 23.5%. How much is this decrease in dollars? How much money was in his account at the end of last year?

Answers

Given:

Initial amount = $8600

The amount in the account had decreased by 23.5%.

To find:

Decrease in amount and amount at the end of last year.

Solution:

The amount in the account had decreased by 23.5%. So,

Decreased amount = 23.5% of 8600

[tex]=\dfrac{23.5}{100}\times 8600[/tex]

[tex]=23.5\times 86[/tex]

[tex]=2021[/tex]

Now, the amount at the end of the last year is

Amount = Initial value - Decreased value

[tex]Amount=8600-2021[/tex]

[tex]Amount=6579[/tex]

Therefore, the decreased value is $2021 and the amount at the end of last year is $6579.

An 18-pound bag of dog food is $27. What is the constant of proportionality that relates cost in dollars, y, to the number of pounds of dog food, x ?

Answers

Constants of proportionality are involved with direct variation. Direct variation takes the form y = kx where y is the dependent variable; k is the constant of proportionality; and x is the independent variable. The formula for this problem is: 27 = k(18). When you divide both sides by 18, you find that k = 3/2.

Which polynomial function has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1? f(x) = (x – 2i)(x – 3i) f(x) = (x + 2i)(x + 3i) f(x) = (x – 2)(x – 3)(x – 2i)(x – 3i) f(x) = (x + 2i)(x + 3i)(x – 2i)(x – 3i)

Answers

Answer:

[tex]P(x)=(x-2i)(x-3i)[/tex]

Step-by-step explanation:

Build a Polynomial Knowing its Roots

If we know a polynomial has roots x1, x2, ..., xn, then it can be expressed as:

[tex]P(x)=a(x-x1)(x-x2)...(x-xn)[/tex]

Where a is the leading coefficient.

Note the roots appear with their signs changed in the polynomial.

If the polynomial has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1, then:

[tex]P(x)=1(x-2i)(x-3i)[/tex]
