What are the zeros of the polynomial function f(x) = x3 - 2x2 - 24x? (1 point)

vodka [1.7K]

f(x) = x³ - 2x² - 24x

x³ - 2x² - 24x = 0

x(x² - 2x - 24) = 0

x = 0

x² - 2x - 24 = 0

a = 1, b = -2, c = -24

Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100

x = (-(-2) - 10)/(2 * 1) = -8/2 = -4

x = (-(-2) + 10)/(2 * 1) = 12/2 = 6

The bookstore at suntan U Had a sale on school t shirts. Thursday they sold 45 of the marked down t-shirts for a total of 406.50

Kisachek [45]

Answer:

The number of women's shirt sold is 32.

The number of men's shirt sold is 13

Step-by-step explanation:

Total number of T shirts sold on Thursday = 45

Total amount it was sold for : 406.50

Cost of each women's t shirt = 9.25

Cost of each men's t shirt = 8.50

Here, let the number of women's shirt sold= k

So,number of men's shirt = Total shirts sold - Women's shirt

= 45 - k

Also, total amount earned = Amount earned from men's shirt + amount earned from women's shirt

or, 406.50 = k(9.25) + (45 -k)(8.50)

⇒ 406.50 = 9.25 k - 8.50 k + 382.5

or, 24 = 0.75 k

⇒ k = 24/0.75 = 32

Hence, the number of women's shirt sold is 32

And the number of men's shirt sold = 45 - 32 = 13

Brut [27]

Let x = cups of 11% wheat, and y = cups of 63% wheat

He wants 12 cups in total, so we need:

x + y = 12

These 12 cups need to have 50% wheat, which means we are looking at 12*.5 = 6 cups of wheat in total, so our second equation is:

.11x + .63y = 6

We have two equations and two variables. So we can solve by using any means you want. I used substitution:

x = 12 - y

.11(12-y) + .63y = 6

1.32 -.11y + .63y = 6

.52y = 4.68

y = 9

Which means x = 3

Thus, 3 cups of 11% and 9 cups of 63%.

The following probabilities are based on data collected from U.S. adults. Individuals are placed into a weight category based on

sweet-ann [11.9K]

Answer:

the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) is 0.394

Step-by-step explanation:

Given the data in the question;

Underweight Healthy Weight Overweight (not Obese) Obese

Probability 0.017 0.377 0.343 0.263

P( underweight) = 0.017

P( Healthy Weight) = 0.377

P( Overweight (not Obese) ) = 0.343

P( Obese ) = 0.263

now, the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) range will be;

P( weigh less than overweight(but not obese) = P( underweight) + P( Healthy Weight)

P( weigh less than overweight(but not obese) = 0.017 + 0.377

P( weigh less than overweight(but not obese) = 0.394

Therefore, the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) is 0.394
