Answer:
Quadrant I
Step-by-step explanation:
To find in which quadrant an angle is, you have to locate it between 0 and 360.
Since your angle is larger than 360 degrees, we subtract 360 degrees from it.... to get 27 degrees.
27 degrees and 387 degrees lie on the same spot, since they are exactly one turn around from each other.
Now, angles between 0 degrees and 90 degrees are in quadrant I
angles between 90 and 180 degrees are in quadrant II
Angles between 180 and 270 degrees are in quadrant III
Angles between 270 and 360 degrees are in quadrant IV
So, an angle of 27 degrees would land in Quadrant I.... so is 27 + 360x, where x is any integer representing a number of turns.
The answer is:
The terminal side of the angle 387° lies at the Quadrant I.
Why?We know that there are four quadrants on the plane, those quadrants goes from 0° to 360°, however, since the quadrant is going only from 0° to 360°, if we want to know where an angle greater than 360° is located, we need to take only the excess, so:
We are asked to find where the angle 387° is located, we can write the angle by the following way:
[tex]387\°=360\°+27\°\\[/tex]
So, we have that there are 27° more than 360°, if we want to find where the 367° we only need to locate where the excess (27°) angle is located.
Also, we know that:
Quadrant I: 0° to 90°
Quadrant II: 90° to 180°
Quadrant III: 180° to 270°
Quadrant IV: 270° to 360°
We have that 27° is between 0° and 90°, so, it's located on the first quadrant.
Hence, we have that the angle 367° is located at the Quadrant I.

select the correct statement about the function represented by the table.
The correct statement about the function represented by the table is:
D. It is a linear function because the y-value increase by an equal difference over equal intervals of x-values.
Step-by-step explanation:The table of values are given as follows:
x y
1 26
2 44
3 62
4 80
5 98
We know that the function is said to be linear if the rate of change is constant.Here with the x-value is increasing by each 1.
Hence, we will check whether the difference in y-value is equal or not.
( Since, the rate of change is the ratio of the change in y-value to the change in x-value)
Hence,
44-26=18
62-44=18
80-62=18
and 98-80=18
Hence, we get that the change in y-value is equal .
Hence, we get that the slope or rate of change of the function is constant.
Hence, the function is linear.

What is the value of (63 + 9) ÷ 3(2) ? A 8 B 12 C 48 D 576
For this case we have the following expression:
(63 + 9) ÷ 3 (2)
To find the value of the expression we must first solve the terms associated with parentheses, that is:
[tex](63 + 9) = 72\\3 (2) = 6[/tex]
So:
72 ÷ 6 =
12
So, the correct option is 12.
Answer:
(63 + 9) ÷ 3 (2) = 12
Option B
First add the numbers inside the parentheses, then divide the result by 3, and finally multiply that result by 2. The final answer is 48, matching option C.
First, we add the numbers inside the parentheses: 63 + 9 = 72.Next, we must carry out the division and then the multiplication in the order they appear, keeping in mind that multiplication and division are on the same level of the order of operations (PEMDAS/BODMAS rules). So, we first divide 72 by 3, which gives us 24.Finally, we multiply the result by 2. Thus, 24 * 2 = 48.Therefore, the answer to (63 + 9) ÷ 3(2) is 48, which corresponds to option C.

Let f (x) = 1/x
and g(x) = x² – 3x. What
two numbers are not in the domain of fºg?
For this case we have the following equations:
[tex]f (x) = \frac {1} {x}\\g (x) = x ^ 2-3x[/tex]
We must find [tex](f_ {o} g) (x):[/tex]
By definition of composition of functions we have to:
[tex](f_ {o} g) (x) = f (g (x))[/tex]
So:
[tex](f_ {o} g) (x) = \frac {1} {x ^ 2-3x}[/tex]
We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.
[tex]x ^ 2-3x = 0\\x (x-3) = 0[/tex]
So, the roots are:
[tex]x_ {1} = 0\\x_ {2} = 3[/tex]
The domain is given by all real numbers except 0 and 3.
Answer:
x other than 0 and 3
ANSWER
0 and 3
EXPLANATION
The given functions are
[tex]f(x) = \frac{1}{x} [/tex]
and
[tex]g(x) = {x}^{2} - 3x[/tex]
[tex]( f \circ g)(x) = f(g(x))[/tex]
[tex]( f \circ g)(x) = f( {x}^{2} -x )[/tex]
[tex]( f \circ g)(x) = \frac{1}{ {x}^{2} - 3x} [/tex]
Factor the numerator:
[tex]( f \circ g)(x) = \frac{1}{ x(x - 3)} [/tex]
The function will be undefined if the denominator is zero.
[tex]x(x - 3) \ne0[/tex]
[tex]x \ne0 \: and \: x \ne3[/tex]
Therefore 0 and not in the domain of the composed function.

Answer:
x = 30.
Step-by-step explanation:
The angle next to the 60 degree angle = 180 - 60 = 120 degrees (adjacent angles are supplementary).
Let the angle just above 3x be y. The sum of 3x and y = 120 degrees (as opposite angles of a parallelogram are equal).
We have the following equations.
3x + y = 120............(1)
2x + 90 + y = 180
2x + y = 90.............(2)
Subtracting, (1) - (2):
x = 30.

Answer:
A) P(stars) = 1/3
B) P(odd)= 4/7
C)P(solid grays or stars or striped)= 1
D)P(1,4 or 7)= 3/7
E)P(not striped)= 2/3
Step-by-step explanation:
Given:
sample set contains 1-7 solid gray, 1-7 stars and 1-7 striped cards
Let solid gray be x
stars be y
striped be z
then sample set be
1x,2x,3x,4x,5x,6x,7x,
1y,2y,3y,4y,5y,6y,7y,
1z,2z,3z,4z,5z,6z,7z
total number of cards in sample set =21
Now
a)Finding probability of stars
Number of star cards in above sample set = 7
P(stars)= 7/21
P(y)=1/3
b)Finding probability of odd
Number of odd cards in above sample set = 12
P(odd)= 12/21
=4/7
c)Finding probability of solid grays or stars or striped
P(solid grays or stars or striped) = P(x or y or z)
=P(x U y U z)
As the events are mutually exclusive
P(x U y U z)= P(x)+P(y)+P(z)
now P(x)= 1/3
P(y)=1/3
P(z)=1/3
P(x U y U z) = 1/3 + 1/3 + 1/3
= 3/3
=1
d)Finding probability of 1,4 or 7
Number of 1,4 or 7 cards in above sample set = 9
P(1,4 or 7) = P(1 U 4 U 7)
As the events are mutually exclusive
P(1,4 or 7) = P(1) + P(4) + P(7)
P(1)= 3/21
=1/7
P(4)= 3/21
=1/7
P(7)= 3/21
=1/7
P(1,4 or 7)= 1/7 + 1/7 + 1/7
=3/7
e)Finding probability of not striped
Number of not striped cards in above sample set = 14
P(not striped)= 14/21

Answer:
Point Q is (3 , 4)
Step-by-step explanation:
* Lets revise the rule of the point which divides of a line segment in
a ratio
- If point (x , y) divides the line segment AB, where A is (x1 , y1) and
B is (x2 , y2) in the ratio m1 : m2
∴ x = [m2(x1) + m1(x2)]/(m1 + m2)
∴ y = [m2(y1) + m1(y2)]/(m1 + m2)
* Now lets solve the problem
- Point Q divides ST in the ratio 5 : 2 where S (-2 , -6) and T (5 , 8)
- To find the coordinates of point Q use the same rule above
# Q is (x , y)
# S is (x1 , y1) and T is (x2 , y2)
# m1 : m2 is 5 : 2
∵ x1 = -2 and y1 = -6
∵ x2 = 5 and y2 = 8
∵ m1 = 5 and m2 = 2
- Substitute these values in the rule
∵ x = [m2(x1) + m1(x2)]/(m1 + m2)
∴ x = [2(-2) + 5(5)]/(5 + 2) ⇒ multiply the numbers
∴ x = [-4 + 25]/7 ⇒ add
∴ x = [21]/7 ⇒ Divide
∴ x = 3
* The x-coordinate of Q is 3
∵ y = [m2(y1) + m1(y2)]/(m1 + m2)
∴ y = [2(-6) + 5(8)]/(5 + 2) ⇒ multiply the numbers
∴ y = [-12 + 40]/7 ⇒ add
∴ y = [28]/7 ⇒ Divide
∴ y = 4
* The y-coordinate of point Q is 4
∴ Point Q is (3 , 4)

Vicky's checking account charges a $12.25 monthly service fee and a $0.26
per-check fee. If Vicky writes 16 checks per month, should she switch to a checking account that charges a $16.50 monthly service fee and no per-check fee?
Answer:
No
Step-by-step explanation:
0.26*16 + 12.25 = 16.41
16.41 < 16.50
Answer:
No, Vicky should not switch.
Step-by-step explanation:
Vicky's checking account charges a monthly service fee = $12.25
Account also charges per-check fee = $0.26
Vicky writes checks per month = 16
His total monthly charges = 12.25+( 16 ×0.26 )
= 12.25 + 4.16
= $16.41
Another account that charges a $16.50 monthly service fee and no per-check fee.
Comparison between account = 16.50 > 16.41
So Vicky should not switch to another account because it charges more than her current account.

Which is the same function as -3x + 7 = y?
a)f(x) = -3x + 7
b)f(-3x) = 7
c)f(7) = -3x
d)f(x) = -3 + 7
Answer:
A) f(x) = -3x+7
Step-by-step explanation:
f(x) is interchangeable with y when writing a function, so the functions are the same.
The function that corresponds to the equation -3x + 7 = y is f(x) = -3x + 7, which maintains the same relationship between x and y as the given equation.
Explanation:The equation -3x + 7 = y can be rewritten in function notation, which typically uses the format f(x) = some expression involving x. The correct corresponding function is one that maintains the relationship between x and y as displayed in the original equation. Therefore, among the options provided:
a) f(x) = -3x + 7 is the correct answer because it is exactly the original equation -3x + 7 = y written in function notation.b) f(-3x) = 7 incorrectly suggests that -3x is the variable and not just x.c) f(7) = -3x suggests that 7 is the variable, which is incorrect.d) f(x) = -3 + 7 is simply the sum of two numbers and does not involve the variable x in a way that matches the original equation.The correct answer indicates that the function of x (f(x)) is given by the linear equation -3x + 7.

Find the missing angle of a triangle if the first two values are 91* and 87 degrees
Answer:
The missing angle has a measure of 2 degrees.
Step-by-step explanation:
Every triangle's inner angles can be added and will always equal 180. Therefore, use subtraction to find any missing angle. In this case,
180 - 91 = 89
89 - 87 = 2
So, your answer is 2.
If the two angles of the triangle are 91° and 87°. Then the measure of the third angle of the triangle will be 2°.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The two angles of the triangle are 91° and 87°.

The scale factor [tex]\( k \)[/tex] is [tex]\( \frac{x}{6} = \frac{10}{6} = \frac{5}{3} \)[/tex].
The scale factor between two similar triangles is the ratio of the corresponding side lengths. In this case, we can find the scale factor by comparing the corresponding sides of triangles FGH and MNO.
Let's denote the scale factor as [tex]\( k \)[/tex]:
[tex]\[ k = \frac{MN}{FG} \][/tex]
Given that NO = 15 units and FG = 6 units, and MN is denoted as [tex]\( x \)[/tex], we can substitute these values into the formula and solve for [tex]\( x \)[/tex]:
[tex]\[ k = \frac{x}{6} \][/tex]
Since [tex]\( k = \frac{NO}{FG} \)[/tex] we can set up the equation:
[tex]\[ \frac{x}{6} = \frac{15}{9} \][/tex]
Now, solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{15}{9} \times 6 \][/tex]
[tex]\[ x = 10 \][/tex]
So, the scale factor [tex]\( k \)[/tex] is [tex]\( \frac{x}{6} = \frac{10}{6} = \frac{5}{3} \)[/tex].
The scale factor of the given figures is 5 : 3.

What is the scale factor?
Scale factor is calculated by finding the ratio of the dimensions of the new shape to the dimensions of the original shape.
15 : 9 = x : 6
15/9 = x/6
Cross product
15 × 6 = 9 × x
90 = 9x
Divide both sides by 9
x = 90/9
x = 10
Therefore, the scale factor 15 : 9

sqrt(64 in^2) = sqrt(s^2)
8 in =s
Answer:
8 inStep-by-step explanation:
The formula of an area of a square:
[tex]A=s^2[/tex]
s - side length
We have the area
[tex]A=64\ in^2[/tex]
Substitute:
[tex]s^2=64\to s=\sqrt{64}\\\\s=8\ in[/tex]
[tex]\sqrt{64}=8[/tex] because [tex]8^2=64[/tex]
I need help with this question
Answer: First option.
Step-by-step explanation:
Given the function f(x):
[tex]f(x)=2x-7[/tex]
And the function g(x):
[tex]g(x)=-6x-3[/tex]
You need to add them to get [tex]f(x)+g(x)[/tex]. Then:
[tex]f(x)+g(x)=(2x-7)+(-6x-3)[/tex]
Therefore, when you add the like terms you get that [tex]f(x)+g(x)[/tex] is:
[tex]f(x)+g(x)=2x-7-6x-3[/tex]
[tex]f(x)+g(x)=-4x-10[/tex]
Since it is a linear function, the Domain is: All real numbers.
You can observe that the result obtained matches witht the first option.
