Answer:
7
Step-by-step explanation:
5L:25Seconds=1L:5seconds
In 50 seconds there will be 10L of water
In 45 We will have to subtract 1L because we are exceeding 5 seconds and in 5 seconds 1L of water comes out
10L-1L=9L
There will be 9L of water
Answer:
x=0.450765 or x=−0.950765
Step-by-step explanation:
14x² + 7x - 6
→ Find the product, sum and factors
Product = -6
Sum = 7
Factors = No factors
→ Since there are no factors utilise the quadratic formula
→ List the values of a, b and c
a = 14
b = 7
c= -6
→ Substitute into the formula
→ Simplify
x=0.450765 or x=−0.950765
<span>He relationship between rectangular and rotational coordinates can be represented by the vector equation:
r = xi +yj = rcos(theta)i+rsin(theta)j
What values in radians makes
x minimum
y maximum
and x = -y
Ans : x minimum = -r when theta = 180 degrees + any multiple of 360 degrees
y minimum = -r when theta = 270 degrees + any multiple of 360 degrees
x = -y when theta = 135 degrees + any multiple of 180 degrees.</span>
