Answer: The equation is W^2 + 4W - 96= 0
{Please note that ^2 means raised to the power of 2}
Step-by-step explanation: We have been given hints as to the measurement of the length and width of the rectangle. The length is given as four more than the width. What that means is that whatever is the width, we simply add four to get the measurement of the length. Therefore if the width is W, then the length is W + 4.
That is,
L = W + 4 and
W = W
Also we have the area given as 96.
Remember that the area of a rectangle is given as
Area = L x W.
In this question, the Area is expressed as
Area = (W + 4) x W
96 = W^2 + 4W
Subtract 96 from both sides of the equation and we have
W^2 + 4W - 96 = 0.
We now have a quadratic equation from which we can determine the dimensions of the rectangle
Answer:
10 water bottles
Step-by-step explanation:
We know that there are a total of 1000 milliliters in a 1 liter. So we first need to multiply 1000 milliliters by 5 in order to calculate how much is in 5 liters which is what the coach is asking for...
1000 * 5 = 5000 milliliters
Since each water bottle only holds 500 milliliters we need to divide this amount by the total that the coach needs in milliliters.
5000 / 500 = 10
Finally, we can see that Audrey needs to buy a total of 10 water bottles to have exactly enough water.
Answer:
-0.017°c/km
Step-by-step explanation:
for the contour provided , to estimate the value of directional derivative of this temperature function at Dubbo, New South Wales in the direction of sydney.
to also find the units,
it is posible to find the directional derivative for the temperature by calculating the rate of change of temperature on an average. This is found in between points at which a straight line can be drawn in between cities that crosess the zone temperature.
to find the direction of sydney, the change in temperature is from 30 to 24 degrees. from the scale that is there, the distance between the two cities are 350km
thus,
24 -30/350
= -0.017deg/km
therefore the required value is -0.017°c/km
