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
Answer:
<h2>A = 22.6°</h2><h2>B = 67.4°</h2>
Step-by-step explanation:
Trigonometry:
Use Sine when you have the Opposite and the Hypotenuse.
Use Cos when you have the Adjacent and the Hypotenuse.
Use Tan when you have the Opposite and the Adjacent.
The Opposite is opposite the angle.
The Adjacent is next to the angle
The Hypotenuse is opposite the right angle.
<u>Angle A:</u>
Use Tan when you have the Opposite and the Adjacent.
Tan-1
= 22.6198... ~ 22.6°
<u></u>
<u>Angle B:</u>
Use Tan when you have the Opposite and the Adjacent
Tan-1
= 67.380... ~ 67.4°
22.6° + 67.4° + 90° = 180°
Answer:
B AND E
Step-by-step explanation:
hope that helpsndbwbe
Ok so 65 percent of 10,000 is 6500. This means that she has to get the other 3500 herself. Since she has a year to save divide 3500 by 12 for each month of the year which is equal to $291.67. Then simply round up to get your answer which is A. $292.
Hope this helped and good luck
In the graph you can see the point are crossing Y -1 and x= 2,
x-y=xy
