8.62206048 kilometers

We know that 1 km is equal to 0.621371 miles. So then we can use this conversion to get the amount of kilometers we have:

\frac{1km}{0.621371mi}*\frac{5.3575mi}{1}  =8.62km

Therefore when we make the conversion, we know that 5.3575 miles is equal to 8.62 km.

(ar^b) ^4 = 16r^20 where a and b are positive integers work our a and b​
ivolga24 [154]

Answer:

a = 2

b = 5

Step-by-step explanation:

Given :

(ar^b)^4 = 16r^20 ; a and b are positive integers :

Opening the bracket :

a^4r^4b = 16r^20

a^4 = 16 - - - - - (1)

r^4b = r^20 - - - (2)

a^4 = 16

Take the 4th root of both sides :

(a^4)^(1/4) = 16^1/4

a = 2

From (2)

r^4b = r^20

4b = 20

Divide both sides by 4

4b/4 = 20/4

b = 5

Hence ;

a = 2

b = 5

All polynomials have at least one maximum.<br> O A. True<br> O B. False
Advocard [28]

Answer: B) False

A counter-example would be the cubic polynomial y = x^3 which doesn't have a max or a min. The graph stretches forever in both directions (up and down) indicating that the range is the set of all real numbers.

Need help understanding the formula
ololo11 [35]

For this case we have the following equation:

H (t) = -16t ^ 2 + vt + s

Where,

t: time

v: initial speed

s: initial height

Substituting values we have:

H (t) = -16t ^ 2 + 15t + 4

By the time the ball hits the ground we have:

-16t ^ 2 + 15t + 4 = 0

From here, we clear the value of time:

Using the quadratic equation we have:

t=\frac{-15+/-\sqrt{15^2-4(-16)(4)}}{2(-16)}

Doing the calculations we have:

t1=-0.217\\t2=1.154

Discarding the negative root, we have that the time is:

t=1.154

Answer:

it takes the ball to hit the floor about:

1.15 seconds
