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.

If y = 5x2 – 3x + k does not hit the x-axis, then what is/are the value(s) of k?
Answers
9514 1404 393
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
so k > 9/20

How should I explain how I got my answer?
Answers
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.

Answers
Answer:
x-60
Step-by-step explanation:
You have to factor out the quadratic.
You know that one of the factors is x-40.
To factor:
Find a number that when added to -40, gives you -100, and also when multiplied, gives you 2400.
That such number is -60.
Add an x before it, and you get (x-60)
