Answers

I will assume the square root extends all the way across.

$√(48a^4b^5c^3)$

$√(2^4\cdot3\cdot a^4b^5c^3)$

$√((2^2)^2\cdot3\cdot(a^2)^2\cdot(b^2)^2\cdot b\cdot c^2\cdot c)$

$√((4)^2\cdot3\cdot(a^2)^2\cdot(b^2)^2\cdot b\cdot c^2\cdot c)$

$√((4\cdot a^2 \cdot b^2 \cdot c)^2\cdot3\cdot b\cdot c)$

$4\cdot a^2\cdot b^2\cdot c√(3\cdot b\cdot c)$

$\boxed{4a^2b^2c√(3bc)}$

Express the complex number in trigonometric form.

3 - 3i

Answers

z = a + bi
z = 3 - 3i

|z| = √(a² + b²)
|3 - 3i| = √(3² + 3²)
|3 - 3i| = √(9 + 9)
|3 - 3i| = √(18)
|3 - 3i| = √(9 × 2)
|3 - 3i| = √(9)√(2)
|3 - 3i| = 3√(2)

Max travels to see his brother's family by car. He drives 216 miles in 4 hours. What is his rate in miles per hour? B) Suppose he makes two stops of 10 minutes each during his journey. Will he be able to reach the town in 4 hours if he keeps the speed the same?

Answers

Answer:

54 miles/hour

If he made two stops of 10 minutes each and maintains the same speed, it would take him more than 4 hours to reach the town as the time speed would have been extended by 20 minutes.

Step-by-step explanation:

The rate of change of distance with time is called speed and it is measured in miles per hour. Mathematically,

Speed = Distance/time

His rate in miles per hour is his speed

= 216/4

= 54 miles per hour

Answer:

Rate in miles per hour: 54 miles per hour

HELP ME PLEASE!!What are the domain and range of the function f(x)=1/4(x^3+6x^2+5x-4)

choices:
domain: (-5,0)
range: (-2,0.5)

domain: (-3.5, 2.5)
range: (-0.5, -1.3)

domain: (infin., 1/4)
range: -4, infin.)

domain: (-infin., infin.)
range: (-infin., infin.)

Answers

Answer:

domain: (-infin., infin.)

range: (-infin., infin.)

Step-by-step explanation:

This is an odd degree polynomial which forms a sideways S shape starting low and ending high. Since nothing restricts the function from having an output for every real number input, the domain and range are (-infin., infin.).
