Answer:

h'(t)= -12

Step-by-step explanation:

h'(t)=d/dt (-6t x 2 + 24 + 6)

h'(t)=d/dt (-12t + 24 + 6)

h'(t)=d/dt (-12t + 30)

h'(t)=d/dt (-12t) + d/dt (30)

h'(t)= -12+0

A 45 foot ladders leaning up against a building. The base of the latter is 20 feet away from the building. What is the angle of
Tatiana [17]

Answer:

The angle of elevation to the top of the building is 63.61 degrees

Step-by-step explanation:

Here, we want to calculate angle of elevation to the top of the building.

For this, we need a triangle

Please check for this in the attachment.

From the diagram, we are to calculate the angle theta.

To do this, we use trigonometric identities.

Looking at what we have, we have the hypotenuse and the adjacent.

So the trigonometric identity to use is the cosine

Mathematically Cosine theta = adjacent/hypotenuse

Thus, Cos theta = 20/45

Cos theta = 0.444444444444444

Theta = Arc cos(0.444444444444444)

Theta = 63.61 degrees

Which of the following observations of children is the most objective?
Ivan
I'd say D. A uses words that suggest the author has an opinion of Alex's behavior that is unfavorable. B uses the words "obviously less disciplined" to refer to Sue, which is clearly an opinion and also rather unfavorable. C makes assumptions as to Joan's emotions toward Mary, which cannot be ascertained objectively without asking Joan. D is a clear statement of the facts without embellishment.

EDIT: Note that the definition of objective is not influenced by opinions or beliefs, as opposed to subjective.

What on earth is 7 + √(x - 1) = 2?<br> I'm confused...
Gala2k [10]

Answer: x = 26

Step-by-step explanation:

Let's go step by step.

7 + \sqrt{x-1} = 2\\\sqrt{x-1} = -5\\x-1 = (-5)^2 \\x-1 = 25\\x = 26

Check your answer.

7 + \sqrt{26-1} = 2\\ 7+5 = 2\\12 = 2

That clearly doesn't work, showing how it has no solution.

^The answer above explained it better than me :P
