According to your graphing calculator, what is the approximate solution to the trigonometric inequality
cos(0.65x) > 0.45 over the interval 0
Answer:
B the answer with 1.6985
Step-by-step explanation:
did it on graphing calc
The solution of the inequality is [0, 1.699].
We will graph y=cos(0.65x)-0.45 using a calculator. Image 1.
Then we draw the boundary x=0 and x=[tex]2\pi[/tex] on the same graph. And we try to find where y>0 on that graph. Image 2.
From the graph we see that y>0 that means cos(0.65x) > 0.45 is over the interval [0, 1.699].

Mr. Sartin has 2 gallons of paint that will cover 750 Sq. Ft. He needs to cover 3000 Sq. Ft.. How many more gallons of paint does he need?
Answer:
8 galons
Step-by-step explanation:
line every information by type of units
2 gallons for 750 sq ft
? galons for 3000sq ft
crossmultiply
?*750=2*3000
divide both sides by 750
?=(2*3000) /750= 8

Please help me. i will mark you as most brilliance and give you 5 stars! Please be specific when answering. thank you! :)
Step-by-step explanation:
5x+52=9x+20
subtract 5x on both sides
subtract 20 on both sides
32=4x
divide by 4 on both sides
x=8
plug in x to the equations for A, D, and C
A and D are 92°
C is 56°
B and C will add up to 90, so
90-56=34°
13y-6=34
add 6 on both sides
13y=40
divide by 13
y=40/13 (I don't wanna calculate that)

With a mean of 100 and standard deviation of 15, what percentage of IQ scores are less than 110
Answer:
i think 125
Step-by-step explanation:
If U= {2, 4, 6, 8, 10, 12, 14}, which is a subset of U? * A= {2, 4} A= {1, 3, 5, 7} A= {1} A= {2, 3, 4}
Answer:
Step-by-step explanation:
Given
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
Required
Which of the sets is a subset
A set (Set A) is a said to be a subset of another set (Set B) if the content of that set (i.e. A) can be found in the other set (set B)
Using the above definition, we have:
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
[tex]A = \{2,4\}[/tex]
A is a subset of U because 2 and 4 are in U
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
[tex]A = \{1,3,5,7\}[/tex]
A is not a subset of U because 1,3,5 and 7 are not in U
[tex]U= \{2, 4, 6, 8, 10, 12, 14\}[/tex]
[tex]A = \{2,3,4\}[/tex]
A is not a subset of U because 1,3,5 and 7 are in U
Hence, option A answers the question.

The probability that a male develops some form of cancer in his lifetime is 0.4567. The probability that a male has at least one false positive test result (meaning the test comes back for cancer when the man does not have it) is 0.51. Some of the following questions do not have enough information for you to answer them. Write “not enough information” for those answers. Let C = a man develops cancer in his lifetime and P = man has at least one false positive. a. P(C) =______ b. P(P|C) =______ c. P(P|C') =______ d. If a test comes up positive, based upon numerical values, can you assume that man has cancer? Justify numerically and explain why or why not.

f ( x) = 6 (1 - x ) what is the vaule of (-8)
Answer:
f(x) = 54
Step-by-step explanation:
Plugging in -8 we get f(x) = 6(1-(-8)) since there is a double negative we can simplify it to a positive --> f(x) = 6 (1 +8) now distribute 6 to all factors in ( )
6 times 1 is 6 and 6 times 8 is 48. So now we have 6 + 48 which = 54

Find the slope of the line that passes through (100, 56) and (28,94)
Answer:
-19/36
Step-by-step explanation:
We can find the slope using
m = ( y2-y1)/(x2-x1)
m = ( 94-56)/( 28 -100)
= 38 / -72
= -19/36

Write an article for publication on why students should not cheat during examination
Answer:
The thing with exams, is that they just keep getting harder, and the consequences get more severe. Many people find themselves unable to pursue a career they want because they cannot score high on some test, and they blame the whole stupid system - but they did have 12+ years to practice taking tests.
It seems to arbitrary as a kid, but cheating tactics exist and change at all levels of education - there's not really any cumulative benefit to working on your cheating, and there's not a skill barrier to getting into cheating.
Tests on the other hand are a very arbitrary system, and the skill of taking tests can be trained. If you want to cheat, then study up on exam skills and memory tricks and studying tools. Then learn great ways to score highly on exams and it will be all the fun of cheating but you're never getting in trouble or stressed about getting caught.
In a very...amoralistic sorta way one could consider cheating to be your 'ace in the hole' sorta like steroids and athletic performance. It may be enough to push you to the next level, but if you do it early then you will never have the chance to benefit quite that much again - reputations of academic dishonesty follow you, and getting caught at the very least shows future employers that your discretion is lacking.
In that sense it is probably worthwhile to get as good at school and exams as possible, and only consider cheating when there is some life and death situation on the line and it is justifiable. Cheating is a real strategy, but it has real risks.
If you think of vegas, cheating is like trying to look at someone elses cards, or coordinate a strategy to get money out of a Casino. The casino knows you want to do this and is looking for you to do that. Now if you count cards like that recent movie about the MIT kids, there is nothing physically different about what you do - but you stack the odds in y our favor and can get on a seriously bad side of some Casinos if you are caught doing it.
Now here's the neat thing about tests - you can make way more money by being good at tests than you can by being good at counting cards (with a few notable exceptions) and you're supposed to be counting cards for the exam! The whole idea of the exam is to force you to prepare, and find some way to allow you to prove that you have mastered the material.
Exams will follow you through every stage of life, so getting good at them is an investment, and like I said it never gets easier. Like...try and fail and work new strategies all you want until your last 2 years of highschool - there's no significant consequences for failure at that point. From there forward your future really is on the line, cheat in highschool and you are at the mercy of your administrators and later the admissions officials opinion of cheaters.

Perimeter = 2 x Length + 2 x Width
The perimeter of a rectangle is 66. If the Length is two more
than three times the Width, what is the length of that rectangle?
Answer:
25.25Step-by-step explanation:
Let the width be x
Then the length is 3x + 2Perimeter = 66Perimeter formula
P = 2(l +w)Substitute values
66 = 2(3x + 2 + x)33 = 4x + 24x = 31x = 31/4x = 7.75The length is:
3*7.75 + 2 = 25.25graph y = 2/3x

plz help me thanks so much
Answer:
0
Step-by-step explanation:
The interval -7 <= x <= 1, has endpoints:
(-7, -1) and (1, -1)
There is no rate of change (the y-coordinates are the same), hence if one draws a line to connect the two points, the line will be horizontal. Therefore, the rate of change over the interval is 0.
What is the slope of the line that passes through the points (6, -10)(6,−10) and (3, -13) ?(3,−13)?
Answer:
The slope of the points is (3,3)
Step-by-step explanation:
If you plot both points on a graph and start at the one furthest down on the graph, then go up three and to the right three you get to your second point and you have your slope. Remember going down or to the left makes the slope negative and it is always rise over run.
