Answer:

(0,27)

Step-by-step explanation:

x2 + 27 = 0

Solutions based on quadratic formula:

x1  

= −0 − √ 02 − 4×1×27   2×1 = 0 − 6 × √ 3 i   2 ≈ −5.196152i

x2  

= −0 + √ 02 − 4×1×27   2×1 = 0 + 6 × √ 3 i  2 ≈ 5.196152i

Extrema:

Min = (0, 27)

Answer:

x =i\sqrt{27}

Step-by-step explanation:

x^2+27=0

To solve for x, we need to get x alone

x^2+27=0

Subtract 27 from both sides

x^2+27-27=0-27

x^2=-27

To remove square root , take square root on both sides

\sqrt{x^2} =\sqrt{-27}

x =\sqrt{-27}

The value of square root (-1) is 'i'

x =i\sqrt{27}

If a car with an average speed of 40 miles per hour drives for 45 minutes how far will it have gone
REY [17]

Answer: 30\ miles

Step-by-step explanation:

The average speed of the car is 40 miles per hour:

V=40\ \frac{mi}{h}

The car drives for 45 minutes:

t=45\ min

Since 1 hours has 60 minutes, we can convert the time from minutes to hours:

(45\ min)(\frac{1\ h}{60\ min})=0.75\ h

Knowing these values, we can use the following formula for calculate the distace "d":

d=V*t

Therefore, substituting values into the formula, we get:

d=(40\ \frac{mi}{h})(0.75\ h)\\\\d=30\ mi

The speed, s, of the current in a certain whirlpool is modeled by s=300/d, where d is the distance from the center of the whirlp
JulijaS [17]
For this case we have the following equation:
 s = 300 / d
 Where,
 s: the speed of the current in a certain whirlpool
 d: the distance from the center of the whirlpool
 We have then that:
 If the distance from the center of the whirpool is large, the speed is small.
 If the distance from the center of the whirlpool is very small, the speed tends to infinity
 Answer:
 
Large distance, small speed.
 
Short distance, speed tends to infinity.
