Answer:

35 would be your answer

Step-by-step explanation:

3x-24=81

So first off, add 24 to 24 and 81

You would get 3=105

Now divide 3/3 and 105/3 which will get you 35!

Hopefully this helps!

Answer: 35

Step-by-step explanation:

you add 24 to the other side of the equal sign and you get 105. then you’re left with 3x=105 and you divide 105 by 3 and get 35=x

Answer:

d= 99   e= 81   f= 99

Step-by-step explanation:

Answer:

d = 90

e = 81

f = 99

Step-by-step explanation:

First, find e because you can figure it out by vertical angles. 81 and e are vertical so e is 81. To find f, you subtract 180 by 81 because it's a straight line which is 99. So f is 99. To find d, you can use the right angle next to it. 180-90 is 90. So d is 90.

Answer:

therefore, x is 71 degrees

Step-by-step explanation:

we know that the exterior angle is 142 degrees.

we also know that we have to find x, which is labeled two times as an interior triangle (in the same triangle), so they must be the same degree.

there are different ways to solve this but the easiest way is this:

exterior angle = opposite interior angle 1 + opposite interior angle 2

142 degrees = x + x

142 degrees = 2x

142/2 = x

x = 71

therefore, x is 71 degrees

Answer:

Answer:

Groups of 12, Groups of 4, Groups of 6, Groups of 18

Step-by-step explanation:

12 x 3 = 36

36 splits evenly into 12, 4, 6, and 18 therefore that is your answer.

Answer: 97 degrees

Step-by-step explanation:

I drew some letters on your attachment to make it easier for you to understand.

To find angle y you need to find angle x first, you do that by doing (180=A+B+C) and you solve for A which is x degrees (A=180-B-C)

When you use angle C you must combine the 26 degrees and 55 degrees because if you use only 55 let's say, that would be the angle for triangle CDB, and we need C for triangle ABC.

So: A=180-42-81 -> A=57 degrees

Now you know Angle A (57 degrees) and Angle ACD (26 degrees)

All you have to do to find Y is to do: y=180-x-26

So y would be: 97 degrees

Keep in mind this is one of two solution methods I can see, if you want me to show you the other one as well just tell me in the comments, you are welcome.

Complete Question:

The height of a diver jumping from a diving platform is about [tex]h(t)= 16t^2 +11t+10[/tex], where h is the height of the diver in feet above the water and t is the time measured in seconds, when diving from a platform about 34.3 feet above the water with an upward initial velocity of 11 ft/sec..  After how many seconds is the diver's height above the water 15 feet?

Answer:

0.3125 seconds

Step-by-step explanation:

Given

[tex]h(t)= 16t^2 +11t+10[/tex]

Required

Time when the diver is above 15ft

This implies that h(t) = 15

So, we have:

[tex]15= 16t^2 +11t+10[/tex]

Collect Like Terms

[tex]0= 16t^2 +11t+10 - 15[/tex]

[tex]0= 16t^2 +11t-5[/tex]

[tex]16t^2 +11t-5=0[/tex]

Expand:

[tex]16t^2 + 16t - 5t - 5 = 0[/tex]

Factorize:

[tex]16t(t + 1) - 5(t + 1) = 0[/tex]

[tex](16t - 5)(t + 1)=0[/tex]

Split

[tex]16t - 5 = 0[/tex] or [tex]t + 1 = 0[/tex]

[tex]16t = 5[/tex] or [tex]t + 1 = 0[/tex]

Solve for t

[tex]t = 5/16[/tex] or [tex]t = -1[/tex]

[tex]t = 0.3125[/tex] or [tex]t = -1[/tex]

But time can't be negative. So:

[tex]t = 0.3125[/tex]

Hence, it will take the diver 0.3125 seconds to be at a height above 15 feet

It will take t = 0.3125 seconds is the diver's height above the water 15 feet.

Given ,

The height of a diver jumping from a diving platform is h

 h(t) = [tex]-16t^{2} + vt + 10[/tex]

The diver's height above the water 15 feet

Velocity = v = 11 ft per second

We have to find, t seconds is the diver's height above the water 15 feet.

According to the question,

[tex]h(t) = -16t^{2} +vt+10[/tex]

Where v = 11, h(t) = 15

15 = -16[tex]t^{2}[/tex] + 11t + 10  

15 - 10 = [tex]-16t^{2} + 11t[/tex]

5 = [tex]-16t^{2} +11t[/tex]

[tex]16t^{2} -11t +5= 0[/tex]

[tex]16t^{2} -16t - 5t + 5 = 0[/tex]

16t ( t - 1 ) - 5 ( t + 1 ) = 0

(16t - 5 ) ( t + 1 ) = 0

16t - 5 = 0

16t = 5

t = [tex]\frac{5}{16}[/tex]

t = 0.3125

And t + 1 = 0

t = -1

Time can not be negative so we can't take t = -1 .

So, The required value of time is t = 0.3125

Hence, it will take t= 0.3125 seconds is the diver's height above the water 15 feet.

Answer:

  k > 9/20

Step-by-step explanation:

If the parabola does not touch the x-axis, the discriminant is negative. That means ...

  b^2 -4ac < 0

  (-3)^2 -4(5)(k) < 0

  9 < 20k . . . . . . . . . add 20k

  k > 9/20 . . . . . . . . .divide by 20

[tex]y=5x^2-3x+k\\[/tex]

Discriminant  |  D < 0 (Because doesn't intercept any x-values)

[tex]D = (-3)^2-4(5)(k) < 0\\9-20k<0\\-20k<-9\\k>\frac{9}{20}[/tex]

Therefore, the value of k must be greater than 9/20

Answer: the answer is 37

Step-by-step explanation: someone said it was incorrect but it’s correct trust me my teacher gave us the answer

The area of the square PINT will be 37 square units.

The space occupied by any two-dimensional figure in a plane is called the area. Here we have three shapes a triangle, a rectangle, and a parallelogram.

Given that Square PINT has vertices N(4, 2) and T(3, 8). The area of the square will be calculated by finding the distance between two points N(4, 2) and T(3, 8), and squaring it.

The length of the line segment bridging two points on a plane is known as the distance between the points.

Area = Distance² = ( x₂ - x₁ )² + ( y₂ - y₁ )²

Area = Distance² = ( 4 - 3 )² + ( 8 - 2 )²

Area = Distance² = (1 )² + ( 6 )²

Area = Distance² = (1 )² + ( 6 )² = 37 square units

Therefore, the area of the square PINT will be 37 square units.

Answer:

What is meant by "Explain your answer?"

   On tests & problem sets students are often asked to explain the reasoning behind their answers. They are often frustrated and/or confused by “explain.” What & why are they supposed to explain? Here is one answer:

   It isn't enough to get the right answer -- you have to be able to explain how you got it. To be sure you get enough practice at explaining yourself, it pays to discuss the questions with your fellow students and/or to write out explanations of your reasoning. You need to both

           (1) Include the right facts, principles, etc., AND

           (2) Explain the logic that you used to solve the problem. How did you get from the facts to the answer?

   It is not sufficient to pile up unselected facts (even if they are correct), OR just to state the facts (even if they are the right ones), without explaining how they relate to the problem at hand, OR to just explain the logical train of thought (even if it is correct), without any specifics.

   That's what you shouldn't do. What should you aim for??

   Try to explain as if you were talking to a fellow student in the class who is generally intelligent, prepared, etc., but can't figure out this particular question.  In other words, explain your reasoning step by step.  Don't just repeat all the related facts in the book or notes--try to pick out the important, relevant points, put them in logical order, and explain (or diagram) how one leads to the next. (In other words, pretend you are writing a simple* answer key.)

*Note: The keys provided after each exam or problem set are usually quite complex and go beyond what we expect from an individual student. The posted keys tend to be so long and involved because they include not only correct answers (& explanations) but also explanations of common student misconceptions.

How to Get the Most out of Explaining

   When you explain things to yourself, or to others, try not to use pronouns. Use nouns instead. This may sound silly, but it really helps you to be sure that you understand what you are saying. If you use pronouns or vague terms you can fool yourself into thinking you understand when you really don't. An example: Suppose you say "The gene is transcribed and it goes to the cytoplasm and is translated, which uses tRNA and mRNA." What do you mean by it and/or which?  Is it the gene or the mRNA? Does which refer to translation or transcription? Sometimes you know, and you are just using shorthand. But sometimes you don't know, and you don't even realize it until you are forced to pick the right terms to replace "it" and "which."  So try to be as specific as possible instead of as vague and as general as possible. Being specific has multiple advantages. It helps you to learn, it helps listeners understand what you are saying, and it helps graders on exams know that you really understand what you are talking about.

Yes, this is a translation which doesn't change the pre-image size

Answer:

-7

Step-by-step explanation:

First, we need to substitute x in as 14 since that is what x is equal to.

1.  x / y  =>  14 / y

Next, we need to substitute y in as -2 since that is what y is equal to.

2.  14 / y  =>  14 / -2

Now to solve it;

3.  14 / -2  =>  -7

So now we now that x / y equals -7 when x = 14 and y = -2.
