The derivative of the function h(x) = 1 - x^2 sin^-1(x) -x^2-x is h'(x) = - x^2/(sqrt(1-x^2)) - 2x - 1.

What is derivative ?

The derivative of a function is a measure of how much the output of the function changes with respect to the change in its input. It is represented by the symbol "d/dx" or "∂/∂x" and it is a fundamental concept in calculus.

First, we will apply the chain rule to the term -x^2 sin^-1(x)

Let u = sin^-1(x)

du/dx = 1/(sqrt(1-x^2))

so, -x^2sin^-1(x) = -x^2u

then dh/du = -x^2

then dh/dx = -x^2 * (du/dx) = -x^2/(sqrt(1-x^2))

Next, we will differentiate the rest of the function ,

h(x) = 1 - x^2sin^-1(x) - x^2 - x

h'(x) = - x^2/(sqrt(1-x^2)) - 2x - 1

So, the derivative of the function h(x) = 1 - x^2 sin^-1(x) -x^2-x is h'(x) = - x^2/(sqrt(1-x^2)) - 2x - 1.

Answer:

See Below

Step-by-step explanation:

Answer:

Line: Solid

Shade: Above

m = -4/5

b = 2

(0,2) - True -Yes

(3,4) - True - Yes

(-2,-2) - False - No

Step-by-step explanation:

Given:

4x + 5y ≥ 10

Questions:

Line: Solid or Dashed?

Shade: Above or Below?

m= [?]

b= [?]

Are these points solution:

Solve:

Inequalities that use '< or >' symbols are plotted with a dashed line. Due to that dashed line means the solution doesn't include the line itself.

< = Less than

> = Greater than

Inequalities that use '≤ or ≥' symbols are plotted with a solid line. Due to that solid line means the solution does includes the line itself

≤ = Less than or equal to

≥ = Greater than or equal to

Therefore, based on the given, the line is solid. Which also means the solution does includes the line itself.

We also know that the given info with the inequalities of "≥".

"≥" Means greater than or equal to which means shade above. If it was "≤ " which means less than or equal to you have to shade below.

To find the m and b we first have to know that;

y = mx + b

m = Slope

b = y-intercept

To find the Slope(m) and b(y-intercept) we first have to put 4x + 5y ≥ 10 in  slope-intercept form.

4x + 5y ≥ 10

4x-4x + 5y ≥ 10-4x {Subtract 4x from both sides}

5y ≥ -4x + 10

5y ≥ -4x + 10 {Divided all by 5}

5y/5  ≥ -4x/5 + 10/5

y =-4/5x+2

Hence, now we know that;

m = -4/5

b = 2

To see if the following points {(0,2) (3,4) (-2,-2)} are solutions for 4x + 5y ≥ 10

All we have to do is to substitute it in.

Starting with (0,2)

x = 0

y = 2

4(0) + 5(2) ≥ 10

0 + 10 ≥ 10

10≥ 10

True. 10 isn't greater than 10 but- It's equal to 10. ≥ Means greater than or equal to Hence, (0,2) is a solution.

Next we have (3,4)

x = 3

y = 4

4(3) + 5(4)  ≥ 10

12 + 20  ≥ 10

32  ≥ 10

True. 32 is greater than 10 - Hence, (3,4) is a solution.

Finally we have (-2,-2)

x = -2

y = -2

4(-2) + 5(-2)  ≥ 10

-8 + -10  ≥ 10

-18  ≥ 10

False. Although you may probably think 18 is greater than 10 it is not correct. -18 isn't greater than 10 due to that it is negative.

The SAS (Side-Angle-Side) Congruence Rule states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.

The SAS (Side-Angle-Side) congruence rule is a method used to determine if two triangles are congruent. This rule states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

To determine if two triangles are congruent using the SAS rule, we must first identify the two sides and the angle in one triangle that are congruent to the two sides and the angle in the other triangle. This means that they must have the same measures in terms of length and angle.

Once we have identified the corresponding sides and angles, we can use the SAS rule to determine if the two triangles are congruent. If the two sides and the angle of one triangle are congruent to the two sides and the angle of another triangle, then the two triangles are congruent.

However, if the two sides and the angle of one triangle are not congruent to the two sides and the angle of another triangle, then the two triangles are not congruent. The SAS rule is a simple and effective way to determine if two triangles are congruent.

Reasons:

The given equation is; 2.3·p - 10.1 = 6.5·p - 4 - 0.01·p

Simplifying the above equation by collecting like terms gives;

2.3·p - 10.1 = 6.5·p - 0.01·p - 4 = 6.49·p - 4

2.3·p - 10.1 = 6.49·p - 4

The driver is safer in the inside lane. The equation for fc=mv^2 states that the force of centripetal acceleration increases with velocity, so the faster the driver goes, the greater the force of centripetal acceleration.

This means that in an icy roundabout, it is safer to drive in the inside lane since the inside lane has a lower speed limit and thus a lower force of centripetal acceleration.

The driver is safer in the inside lane of a roundabout when it is icy, as the equation for fc=mv^2 states that the force of centripetal acceleration increases with velocity, so the lower speed inside lane will have a lower force of centripetal acceleration.

The net yardage the Bobcats football coach logged over four plays of game is  19.8x - 11.1y

The net yardage is calculated using the addition and subtraction operation as follows

For the gains the calculation is as follows

= Gain 25x yards + Gain 0.9y yards.

= 25x + 0.9y

For the lose the calculation is as follows

= Lose 12y yards + Lose 5.2x yards.

= 5.2x + 12y

the net yardage is solved as follows

net yardage = gains - loses

net yardage = (25x + 0.9y) - (5.2x + 12y)

removing the parenthesis and rearranging

net yardage = 25x + 0.9y - 5.2x - 12y

net yardage = 25x - 5.2x + 0.9y - 12y

An area can be represented by the given formula:

[tex]F = 1500(1.02)^t[/tex]

where t represents the number of years since 2004.

The y-intercept of this equation is the point where the graph of the equation crosses the y-axis. In other words, it is the value of F when t is equal to 0.

Plugging in t = 0 into the equation above gives us:

F = 1500(1.02)⁰

A mathematical statement

The mathematical statement is give as

1.4m + 3.7n +1 subtracted from 2.3m−1.2n

When this is represented as an expression

We have the following representation

2.3m−1.2n - (1.4m + 3.7n +1)

Express properly

2.3m − 1.2n - (1.4m + 3.7n + 1)

Open the brackets

So, we have the following representation

2.3m − 1.2n - (1.4m + 3.7n + 1) = 2.3m − 1.2n - 1.4m - 3.7n - 1

Collect the like terms

So, we have the following representation

2.3m − 1.2n - (1.4m + 3.7n + 1) = 2.3m - 1.4m  − 1.2n - 3.7n - 1

Evaluate the like terms

So, we have the following representation

2.3m − 1.2n - (1.4m + 3.7n + 1) = 0.9m  - 4.9n - 1

Complete question -

An equation that can you use to find h, the height of the window in meters is: A. 1/2(2h - 2)h = 42.

The height of the window in meters is equal to 7 meters.

Mathematically, the area of a triangle can be calculated by using this mathematical expression:

Area of a triangle = 1/2 × b × h

Where:

Since the window's base area is 2 meters shorter than twice the height, a mathematical expression which can be used to represent it is given by:

Base area, b = 2h - 2

Substituting the given parameters into the area of a triangle formula, we have the following;

Area of a triangle = 1/2 × b × h

42 = 1/2 × (2h - 2) × h

1/2(2h - 2)h = 42 [required equation].

Making the variable h the subject of formula, we have the following;

1/2(2h - 2)h = 42

Cross-multiplying, we have:

(2h - 2)h = 84

2h² - 2h = 84

2h² - 2h - 84 = 0

Dividing all through by 2, we have the following:

h² - h - 42 = 0

Next, we would solve the above quadratic function by using the factorization method;

h² - 7h + 6h - 42 = 0

h(h - 7) + 6(h - 7) = 0

(h + 6)(h - 7) = 0

h = -6 or 7 meters.

Therefore, the height of the window is 7 meters since it can't be negative.

The domain is the area enclosed by the circle, which is all the points inside the unit circle.

The domain of a function is the set of all possible input values (x, y) for which the function is defined and produces a valid output.

For f(x, y) = ln(25 − x2 − 25y2), the function is defined as long as 25 − x2 − 25y2 > 0. This is because the natural logarithm (ln) is only defined for positive numbers. To find the domain, we can set 25 − x2 − 25y2 > 0 and solve for x and y.

25 − x2 − 25y2 > 0

x2 + 25y2 < 25

x2 / 25 + y2 < 1

This is the equation of a unit circle centered at (0,0) with a radius of 1.

As per the trigonometry identity, we know that

sec² (θ) - tan² (θ) = 1

tan² (θ) = sec² (θ) - 1

Apply the square root property to both sides, and we get
