What are the zeros of j(x) in the polynomial equation?

Answers

Answer 1

Answer:

Answer: x = $(-3)/(2)$ , 0, $(3)/(2)$

Step-by-step explanation:

To find the zeros, we will find the solutions to this equation that make it equal 0. This is a cubic function, so we can assume that there will be three solutions.

Given:

$\displaystyle J(x) = (12x^3)/(5) -(27x)/(5)$

Set the functionequal to 0:

$\displaystyle 0 = (12x^3)/(5) -(27x)/(5)$

Subtract:

$\displaystyle 0 = (12x^3-27x)/(5)$

Multiply both sides of the equation by 5:

$\displaystyle 0 = 12x^3-27x$

Factor the polynomial:

$\displaystyle 0 = (3x)(2x-3)(2x+3)$

Solve with the zero product property:

0 = 3x 0 = 2x - 3 0 = 2x + 3

0 = x 3 = 2x -3 = 2x

x = 0 x = $(3)/(2)$ x = $(-3)/(2)$

Use the fundamental identities to simplify the expression. There is more than one correct form of the answer.7 sec^2 x(1 − sin^2 x)

Answers

The fundamental identities that are useful are

Pythagorean relations: cos^2 x + sin^2 x = 1
Inverse trigo identity: cos x = 1/secx

Applying the pythagorean theorem, the equation would be:
7sec^2 x(cos^2 x)
Then applying the inverse trigo identity, the answer would be 7.

Thus, the final answer is 7.

Since there are 5,280 feet in one mile and 3.3 feet in one meter, how many meters per second are equivalent to 60 miles per hour?a.) 26 $(2)/(3)$ meters per second
b.) 198 meters per second
c.) 266 $(2)/(3 (2)/(3) )$ meters per second
d.) 290 $(2)/(5)$
please explain.

Answers

Given:
1 mile = 5280 feet
1 meter = 3.3 feet

convert 60 miles per hour to meters per second

60 miles to meters

60 miles x 5280ft x 1meter = (60*5280m)/3.3 = 316800m/3.3
1 mile 3.3ft
= 96,000 meters

1 hour to seconds

1 hour x 60 minutes x 60 seconds = 1 * 60 * 60sec = 3600 seconds
1 hour 1 minute

unit rate: meters per second

96000 meters ÷ 3600 seconds = 26 2400/3600
simplify 26 2400/3600 ⇒ 26 2/3 meters per second

2400 ÷ 1200 = 2
3600 ÷ 1200 = 3
