Correct question is;
Type the correct answer in the box bellow: If cos x = sin(20 + x)° and 0° < x < 90°, the value of x is ...........
Answer:
x = 35°
Step-by-step explanation:
We are told that;
cos x = sin(20 + x)°
and 0° < x < 90°
From trigonometric identities, we know that;
cos x = sin (90 - x)
Applying to our question gives;
sin (90 - x) = sin (20 + x)°
Comparing both sides, we have;
90 - x = 20 + x
Rearranging;
90 - 20 = x + x
70 = 2x
x = 70/2
x = 35°
Which number line shows the solution of -6x + 18 < 30? WILL GIVE BRAINLIEST PLEASE HELP
Answer:
C.
Step-by-step explanation:
Brainliest me pls
Have a nice day!
Answer:
d. x > -2
Step-by-step explanation:
okay lets simplify this equation
-6x + 18 < 30
first lets subtract 18 from both sides
-6x < 12
now divide both sides by -6
x < -2
important rule: when you multiply or divide an inequality by a negative number, you must flip the inequality sign!
x > -2
answer d matches this inequality
Point Q is the image of Q(4-6) under a translation by 1 unit to the right
Answer:
The image of Q(4,-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)
Step-by-step explanation:
Explanation:-
Given image Q( 4, -6)
Type of transformation change to co-ordinate point
a) Horizontal translation left
'C' units (x, y) ⇒ (x- c, y)
b) Horizontal translation right 'C' units (x, y)⇒( x +c ,y )
c) vertical translation up 'd' units (x, y)⇒( x ,y + d )
d) vertical translation down 'd' units (x, y)⇒( x ,y - d )
Now we will use Horizontal translation right 'C' units
image of Q(4-6) under a translation by 1 unit to the right
Q( 4 , -6) ⇒ The new image R( 4+1 ,-6)
The image of Q(4-6) under a translation by 1 unit to the right then the new coordinate point R( 5 , -6)
Vector you equals (-3,8), and vector v=(-14,6) match each vector operation with the magnitude of its resultant vector
drag the tiles to the boxes to form the correct pairs not all tiles will be used
Answer:
I hope this helps you
Step-by-step explanation:
The magnitude of given operations of vectors are found.
What are Vectors?Vectors are quantities which are having the independent properties of magnitude as well as direction.
Given that,
u = (-3, 8) and v = (-14, 6)
3u = (-9, 24) and 2v = (-28, 12)3u - 2v = (-9+28, 24-12) = (19, 12)
Magnitude of 3u - 2v = [tex]\sqrt{19^2+12^2}[/tex] = [tex]\sqrt{505}[/tex] units
2u = (-6, 16) and 3v = (-42, 18)2u - 3v = (36, -2)
Magnitude = [tex]\sqrt{36^2+(-2)^2}[/tex] = [tex]\sqrt{1300}[/tex] units
u = (-3, 8) and 4v = (-56, 24)u + 4v = (-59, 32)
Magnitude = [tex]\sqrt{(-59)^2+32^2}[/tex] = [tex]\sqrt{4505}[/tex] units
5u = (-15, 40) and v = (-14, 6)5u - v = (-1, 34)
Magnitude = [tex]\sqrt{1157}[/tex] units
7u = (-21, 56) and 2v = (-28, 12)7u - 2v = (7, 44)
Magnitude = [tex]\sqrt{1985}[/tex] units.
Hence the magnitude of vectors are found.

b. domain: {-6, 0, 6), range: {-3, 0, 3}
c. domain: {3, 0, 3), range: {6, 0, 6}
d. domain: {6,0, 6), range: {3, 0,3}
Answer:
The domain: {-3, 0, 3}
The range: {-6, 0, 6}
Therefore, option (a) is correct.
Step-by-step explanation:
Given the table
x -3 0 3
y -6 0 6
Determining the Domain:
We know that the domain of a relation is the set of all the x-values of the set X. In other words, the domain of relation consists of all the input values.Therefore, the domain: {-3, 0, 3}
Determining the Range:
We know that the range of a relation is the set of all the y-values of the set Y. In other words, the range of relation includes all the output values.Therefore, the range: {-6, 0, 6}
Therefore, we conclude that option (a) is correct.

Answer:
The temperature farthest from zero is 5
Step-by-step explanation:
the reason for this is because it doesn't matter whether that temperature is negative or positive because all the question is asking is...."how far from zero"....and would -4 be farther from zero....or would 5 be farther from zero. How I know this is absolute value is always positive. And absolute value of -4....is 4.....and absolute value of 5....is 5.
And 5 is 1 temperature more away from zero than -4.
Answer:
5 is the farthest from 0
-4 is the coldest temperature
5 is the warmest temperature
Step-by-step explanation:
The farthest from 0 could be negative or positive. It's just whichever one has the greatest absalute value (if you know that term, if not...), whichever one you would put up more fingers to count to.
In this case, according to the number line, the farthest from 0 into the nagatives is -4, but the farthest from 0 in the positives is 5. This means that 5 is the farthest from 5 because 5 takes 5 of your fingers to count to, whule -4 (yes, even though it's negative) takes just 4 fingers. This is a good way to visualize it until you can wrap your head around it!
The coldest is the lowest number. In this case, it's below zero. Below zero means negatives. In this case, -4 is the lowest number.
The warmest is the highest number. In this case, it's above zero. That means it's a positive number. 5 is the highest number here.

A polynomial function has x-intercepts at -2, 1/2, and 2 and a relative maximum at x = -1.
Which graph matches the description of this function?
Answer: A :)
Step-by-step explanation:
The function goes through -2, 1/2, and 2, maximum goes through x= -1
By using the information about the x-intercepts and the relative maximum, we can see that the correct option is A.
How to find the correct graph of the polynomial?
First, we know that we have a relative maximum at x = -1, this means that we have a "mountain" at x = -1.
The only two graphs with that feature are A and B.
Now we also know that the x-intercepts are:
-2, 1/2, and 2.
Where the x-intercepts are the values of x at which the graph intercepts the x-axis. There you can see that we have one negative and two positives, from that, we can conclude that the only correct option can be A (because B has two negatives and one positive x-intercepts).
Finally, we conclude that the correct option is A.

Solve for Y
ABC = DEF
Answer:
12
Step-by-step explanation:
△ABC ≅ △DEF means that these two triangles are congruent to each other. Congruent triangles also have corresponding sides and angles that are equal to each other!
This means that angle A corresponds to angle D; and thus, we can set up in equation for these two to solve for y.
First, let's try to decipher what exactly we are solving. Y is what we are multiplying by five to get 60°, or angle A (congruent angle).
Now, we just solve it!
[tex]60=5y[/tex]
y=12
