Find two solutions to the equation (x^3 − 64)(x^5 − 1) = 0.

Rashid [163]

Answer:

the two roots are x = 1 and x = 4

Step-by-step explanation:

Data provided in the question:

(x³ − 64) (x⁵ − 1) = 0.

Now,

for the above relation to be true the following condition must be followed:

Either (x³ − 64) = 0 ............(1)

(x⁵ − 1) = 0 ..........(2)

Therefore,

considering the first equation, we have

(x³ − 64) = 0

adding 64 both sides, we get

x³ − 64 + 64 = 0 + 64

x³ = 64

taking the cube root both the sides, we have

∛x³ = ∛64

x = ∛(4 × 4 × 4)

x = 4

similarly considering the equation (2) , we have

(x⁵ − 1) = 0

adding the number 1 both the sides, we get

x⁵ − 1 + 1 = 0 + 1

x⁵ = 1

taking the fifth root both the sides, we get

$\sqrt[5]{x^5}=\sqrt[5]{1}$

also,

1 can be written as 1⁵

therefore,

$\sqrt[5]{x^5}=\sqrt[5]{1^5}$

x = 1

Hence,

the two roots are x = 1 and x = 4

1. What is 44% of 205

-Dominant- [34]

Answer:

see below

Step-by-step explanation:

If your calculator doesn't have a % key, you can change each of the percentages to a decimal by dividing the numerical value by 100. "%" means "/100".

44% = 44/100 = 0.44 . . . . . . both fractions are read "forty-four hundredths"

Then 44% of 205 = 0.44×205 = 90.2

When you have repetitive calculations like this, a spreadsheet or calculator is handy.

suppose that a player can run at a speed of 15 miles per hour. how many second will it take for the player to run from one corne

kvv77 [185]

answer

15 seconds

set up distance equation

to find the shortest distance between corners, we can use the Pythagorean theorem $a^2 + b^2 = c^2$

a is the width or 160 feet

b is the length or 300 feet

find distance

plug in values to find c, the distance

$a^2 + b^2 = c^2$

$160^2 + 300^2 = c^2$

115600 = $c^2$

c = $\sqrt{115600}$

c = 340 feet

set up time equation

to find the time it takes to run from corner to corner, we can use the equation

$time = \frac{distance}{speed}$

find speed in feet/second

convert the speed of 15 miles/hour into feet/second

$\frac{15miles}{hour} *\frac{5280 feet}{1 miles} * \frac{1 hour}{60 minutes}*\frac{1 minute}{60 seconds}$

= 22 feet/second

find time

since we now know distance and speed with the appropriate units, we can find time

plug values into $time = \frac{distance}{speed}$

distance = c = 340 feet

speed = 22 feet/second

$time = \frac{340}{22}$

time = 15.4545 ≈ 15 seconds
