Answer:
square root of seven
Step-by-step explanation:
multiply the numbers inside the radicals to get fourth root of 49. simplify the radical and get square root of 7
The volume of any "pointy" solid will be 1/3 that of the corresponding prism or cylinder (with same height and base area). The only caveat is that the slope of the sides of the pointy solid is constant.
For your figures: 1/3.
To determine the cost of the mail, we simply substitute the mass of the package to the given function. Mathematical functions are used to relate two variables, observing how changing one variable affects the other variable. For this case, the cost of a mail and the weight of the package are related by the function <span>y = 0.7x2 –2.5x + 3 where x represents the mass in units of pounds (lb) and y is the cost in units of dollars ($). We calculate cost as follows:
</span><span>y = 0.7x^2 –2.5x + 3
</span><span>y = 0.7(5)^2 –2.5(5)+ 3
y = 8 dollars
Therefore, the cost of mailing a 5 lb package would be 8 dollars.</span>
Answer:
13.98 degrees
Step-by-step explanation:
Let the airplane be at point A, the airport at point B and the point of overshoot, point C.
If the plane is on path AC and the pilot wants to adjust to the path AB, the angle by which the pilot will adjust the airplane heading is the angle between AB and AC which is A.
Using Cosine Rule
The pilot should adjust the plane's heading by 13.98 degrees.
