vlada-n [284]

Step-by-step explanation:

$m(d) = 40(d - 35)$

$m = 40d - 1400$

$d = 40m - 1400$

$d = 40(m - 35)$

Katy makes 48 cookies an hour. If she has 24 alr, how long would it take her to make 120?

rosijanka [135]

Question:

Katy makes 48 cookies an hour. If she has 24 already, how long would it take her to make 120?

Answer:

It takes 2.5 hours for Katy to make 120 cookies

Step-by-step explanation:

Given:

Time taken to make 48 cookies = 1 hour

To Find:

Time taken to make 120 cookies = ?

Solution:

Time taken to make 48 cookies = i hour

So now time taken to make 1 cookie = $\frac{1}{48} hour$

So time taken to make 120 cookies

= Number of cookies X time taken to make one cookie

=> $120 \times \frac{1}{48}$

=> $\frac{120}{48}$

=> 2.5 hours

Three roots of a fifth degree polynomial function f(x) are –2, 2, and 4 i. Which statement describes the number and nature of al

bagirrra123 [75]

The correct option is f(x) has three real roots and two imaginary roots.

Given

Three roots of a fifth-degree polynomial function f(x) are –2, 2, and 4 i.

<h3>Complex conjugate</h3>

The complex conjugate of a complex number is the number with an equally real part and an imaginary part equal in magnitude but opposite in sign.

It is given that the roots of the fifth-degree polynomial function are -2, 2, and 4+i.

Since the degree of f(x) is 5, therefore there are 5 roots of the function either real or imaginary.

According to the complex conjugate root theorem, if a+ib is a root of a polynomial function f(x), then a-ib is also a root of the polynomial f(x).

Since 4+i is a root of f(x), so by complex conjugate rot theorem 4-i is also a root of f(x).

From the given data the number of real roots is 2 and the number of 2. The number of complex roots is always an even number, so the last root must be a real number.

Therefore, the correct option is f(x) has three real roots and two imaginary roots.

The following playing cards are used in a game. What is the probability of not selecting a prime number?

dybincka [34]

Answer:

3/7

Step-by-step explanation:

1,2,3,4,5,6,7

The word problem is asking the <u>PROBABILITY</u> OF NOT SELECTING A PRIME NUMBER.

PROBABILITY: THE LIKELIHOOD OF AN EVENT.

There are 7 numbers in this data set. Of the seven numbers, four are prime numbers, three of them are not.

Therefore, the probability of not selecting a prime number is 3 in 7, or 3 out of 7 (3/7).
