Answer:
y = -2x+7
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2x+b
Using the point
3 = -2(2)+b
3 = -4+b
3+4 = b
7=b
y = -2x+7
The maximum speed of a boat at 30 feet length of water is 0.093 nautical miles/hour or knots.
<u>Step-by-step explanation:</u>
- The equation for the maximum speed, s is given by s²= (16/9)x
- where, x is the length of the water line in feet.
It is given that, the modeled equation s²= (16/9)x is used to find the maximum speed in knots or nautical miles per hour.
The question is asked to find the maximum speed when the length of the water is 30 feet.
Therefore, to find the maximum speed in 30 feet water, the given modeled equation is used. So, substitute the 30 feet in place of x.
<u>Now, calculating the maximum speed :</u>
s² = (16/9)(30)
s² = 480 / 9
s² = 53.3
Taking square root on both sides,
s = √53.3
s = 7.3
The maximum speed of a boat at 30 feet length of water is 7.3 nautical miles/hour or knots.
Answer:
19
Step-by-step explanation:
This was done the normal way of multiplying and dividing first:
If p=1 and q=4, evaluate the following expression:
4q − p/p + q = ?
4(4) - 1/1 + 4 = 16 - 1 + 4 = 19
If you wanted to do the addition and subtraction first, the equation would have been:
(4q - p)/(p + q) = ?
(4(4) - 1)/(1 + 4) = 15/5 = 3
With the parentheses, the order of operations is done in the parentheses first.
4.75 = 4 75/100 =
= 475/100 = ( we can divide numerator and denominator by 25 ) = 19/4
Answer:
4.75 as an improper fraction in simplest form is 19/4.
