The square root of negative 100 can be dissected step by step. The square root of 100 is 10 however there is no such thing as square root of something negative, thus the imaginary notion is applied. square root of -1 is equal to i .Hence the answer to this problem is 10 i.

What is the missing number. <br> 5 / 6 = ?/18

Cerrena [4.2K]

Answer:

Step-by-step explanation:

So, we know that 5/6 is equal to something over 18. The denominator of 5/6 is a factor of 18, which makes it easy to find the missing numerator. 6 goes into 18 three times, so let's multiply 5 by 3. We get 15. 5/6=15/18, so your missing number is 15.

A membership at a yoga studio costs 35 per month. Write an equation for the cost of the membership, c, that you pay if you keep

Nadya [2.5K]

The equation would be 35c=x

So if C=20 then 35 x 20 = 700

So it would cost $700 to go to this yoga studio for 20 months

Hope this helps!

A 6,000-liter cistern is empty when water begins flowing into it (at t = 0) at a rate (in L/min) given by Q`(t) = 9 √t, wher

lorasvet [3.4K]

Answer:

a) 6,455 L

b) V(t) = (18/3) * t^(1.5)

Step-by-step explanation:

Part a

Integrating the given relation from t = 0 to t= 105 mins

$V = \int {9 * \sqrt{t} } \, dt\\V = {\frac{9*2}{3}*t^(1.5) = \frac{18}{3}*t^(1.5)\\\\V = \frac{18}{3}*105^(1.5)\\\\\\V = 6,455L$

Part b

$V(t) = \frac{18}{3} * t^(1.5) + C\\Since V = 0 @ t = 0 ; hence, C = 0\\\\V(t) = \frac{18}{3} * t^(1.5)$

A plane can travel 640 miles against the wind in the same time it can travel 800 miles with the wind. If the plane can fly 180 m

alexgriva [62]

Here is how to solve it:
<span>Distance1 ÷ (plane velocity + wind velocity) = Distance2 ÷ (plane velocity - wind velocity)</span>800 / (180 + wv) = 640 / (180 - wv)

115,200 +640 wv = 144,000 - 800 wv

1,440 wv = 28,800

wind velocity = 20 mph
