What is differentiation?

Answers

Answer 1
Answer: Differentiation is a process applied to a function which finds the function's rate of change compared to the rate of change of the independent variable.The result of differentiating a function is called the derivative of the function. It gives the slope of the function's graph at every point.

PLEASE HELP!!! 50 POINTS!! WILL GIVE BRAINLIEST!!!A person standing at the top of Mountain Everest would be approximately 5.5 mi high. The radius of earth is 3959 mi.

PLZ SHOW WORK!!!

Answer:

208.8 mi

Step-by-step explanation:

Form a triangle with the centre of the Earth (C) at one point, the horizon (H) as a second point, and the top of Mt. Everest (O) as the third (see diagram).

Let

r  = Earth’s radius

h = height of Mt Everest

d = distance to horizon

∆CHO is a right triangle.

               d² + r² = (r+h)²

       d² + 3959² = (3959+5.5)²

d² + 15 673 681 = 3964.5²

d² + 15 673 681 = 15 717 260     Subtract 15 673 681 from each side

                     d² = 43 579             Take the square root of each side

                      d = 208.8 mi

The distance from the top of Mt Everest to the horizon is 208.8 mi.

The slope and y-intercept of the given line are -3 and 9 respectively.

What is equation of a line?

The general equation of a line in two variables of the first degree is represented as Ax + By +C = 0, A, B ≠ 0 where A, B and C are constants which belong to real numbers.

When we represent the equation geometrically, we always get a straight line.

Given that, an equation of a line y = -3x+9, we need to determine the slope and the y-intercept of this line,

The slope of a line tell about the steepness and the y-intercept tells the point where it intersects the y-axis,

The slope-intercept form of the equation of a line is given by ;

y = mx+c

Here, m is the slope and c is the y-intercept,

So, the given equation is y = -3x+9

Comparing with the slope-intercept form,

m = -3 and y-intercept = 9

Hence, the slope and y-intercept of the given line are -3 and 9 respectively.

A child is standing across the street from his apartment . His mother is on their balcony . The angle of elevation between the child's eyes and his mothers eyes is 22 degrees . If the distance between their eyes is 32 feet , how far is the child standing from his apartment building ? Round to the nearest foot .

Answers

You've got a leg and an angle next to it (and another, straight one, too), which is enough to calculate any side and angle of the triangle with some knowledge of trigonometry (in my country, you need to be in the last months of 9th grade or later to know that)
To calculate the other angle, you simply substract our known one (22) from 90. Nothing interesting here.
To calculate the hypotenuse, which is actually what is requested, you need to use the cosine of 22, which is about 0.9272, this way: h=l1/cos(L1), that means our distance is 32/0.9272, which is about 34.5131 ft (doesn't matter if there are feet, cm, inches, meters or whatever)

Answer:

30 Ft

Can the square of an integer be a negative number

Answers

If you square an integer, there is no way to get a negative as a result.

Let's look at -5².

-5² means -5 × -5 or 25.

6² means 6 × 6 or 36.

So, there is no way to end up with a negative.

no it can't
minus on minus gives plus
