pleaseee
Answer:
1, 2 and 3
Step-by-step explanation:
First you must know that the coordinate of a point is expressed as (x, y) wgere
x serves as the input value (domain)
y serves as the output values
Given the coordinates (1, 4), (2, 5), (3, 6), the input values will be the values at the x coordinates of the points that is 1, 2 and 3.

(cos2x-cos4x)/(sin2x+sin4x)=
a. cot x
b. tan x
c. sin x
d. cos x
(cos2x+cos4x)/(sin2x-sin4x)=
a. cot x
b. -cot x
c. sin x
d. -tan x
Answer:
[tex](b)\\\tan x, \cot x[/tex]
Step-by-step explanation:
Given
trigonometric function is
[tex]\dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}[/tex]
Applying trigonometric formulae
[tex]\Rightarrow \cos C-\cos D=-\sin (\dfrac{C+D}{2})\sin (\dfrac{C-D}{2})\\\\\Rightarrow \sin C+\sin D=\sin (\dfrac{C+D}{2})\cos (\dfrac{C-D}{2})[/tex]
[tex]\Rightarrow \dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}=\dfrac{2\sin 3x\cdot \sin x}{2\sin 3x\cdot \cos x}\\\\\Rightarrow \dfrac{\sin x}{\cos x}=\tan x[/tex]
option (b) is correct
[tex]\Rightarrow \dfrac{\cos 2x+\cos 4x}{\sin 2x-\sin 4x}=\dfrac{2\cos 3x\cdot \cos x}{2\cos 3x\cdot \sin (-x)}=-\cot x[/tex]

Solve and graph y−5<7
Answer:
y < 12
Step-by-step explanation:
Add 5 on both sides since the opposite of subtraction is addition. Then cross it out where you will be left with y and 7 + 5 equals 12 so the answer is: y < 12
Apply the distributive property to factor out the greatest common factor. 35+14=35+14=35, plus, 14, equals
Answer:
The greatest common factor is 7
[tex]35 + 14 = 49[/tex]
Step-by-step explanation:
Given
[tex]35 + 14 =[/tex]
Required
Apply distributive property
Express 35 as 7 * 5 and 14 as 7 * 2
[tex]35 + 14 = 7 * 5 + 7 * 2[/tex]
Apply distributive property
[tex]35 + 14 = 7 ( 5 + 2)[/tex]
The greatest common factor is 7
Solving further to get the solution
[tex]35 + 14 = 7 * 7[/tex]
[tex]35 + 14 = 49[/tex]
Answer:
7(5+2)

Identify the area of a regular hexagon with side length 17 in. rounded to the nearest tenth.
Answer:
750.8in squared
Step-by-step explanation:
The area of a regular polygon is one-half times the length of the apothem times the perimeter.
Notice that the formula combines the areas for the six triangles that fit inside the hexagon.
The perimeter is equal to the sum of the six triangle bases and the apothem is the height of each triangle.
The interior angles of the hexagon have a measure of 120°
, so the angles at the base of the triangle (and the third angle) have measure 60°
.The height forms a 30°−60°−90°
triangle, which has one leg equal to half of the hexagon side, or 8.5 in.
, and the other leg equal to 8.53–√ in
The figure shows a regular hexagon. Each angle of the hexagon measures 120 degrees. There is a triangle inside the hexagon. The base of the triangle coincides with one of the sides of the hexagon and one of the vertices of the triangle is the center of the hexagon. The length of the apothem is 8.5 times square root of 3 inches. The angles at the base of the triangle measure 60 degrees. The angle between the apothem and the side of the triangle measures 30 degrees. The apothem divides the base of the triangle into two parts. One of the parts is 8.5 inches long.
Find the perimeter of the hexagon.
P=6(17)
Simplify.
P=102in.
The formula for the area is A=12aP
. Substitute the known values and simplify.
A=12(8.53–√)(102)
=433.53–√in2
Round to the nearest tenth as 750.8 in
Therefore, the area of the regular hexagon with side length 17in.
is A≈7508. in2

WILL GIVE BRAINLIEST!!!!!!! find the value of x. find the value of y.
Answer: x=20 y=20√2
Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)

Six jurors are to be selected from a pool of potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, of the prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If jurors are selected at random from this group of , find the probability that the number of potentially prejudiced jurors among the selected jurors is exactly .
Complete question :
Six jurors are to be selected from a pool of 20 potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, 2 of the 20 prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If 6 jurors are selected at random from this group of 20, find the probability that the number of potentially prejudiced jurors among the 6 selected jurors is ;
a. exactly 1
b. none
c. at most 2
Answer:
0.442 ; 0.479 ; 1
Step-by-step explanation:
Given:.
Total number of candidates = 20
Number of jurors to be selected = 6
Number of prejudiced jurors = 2
Required outcome / Total possible outcomes :
Using the combination formula :
nCr = n! ÷ (n-r)!r!
1.)
P(number of prejudiced jurors is exactly 1) :
[2C1 * 18C5] ÷ 20C6
(2*8568)÷ 38760
= 0.442
B.)
P(None of the jurors is prejudiced) :
[2C0 * 18C6] ÷ 20C6
(1 * 18564) ÷ 38760
= 0.479
C.)
P(at most 2 of the jurors are prejudiced)
P(x =0) + p(x = 1) + p(x = 2)
P(x = 2) :
[2C2 * 18C4] ÷ 20C6
(1 * 3060) ÷ 38760
= 0.079
P(x =0) + p(x = 1) + p(x = 2)
(0.479 + 0.442 + 0.079)
= 1
A rectangle is 1 2/5 in. by 2 1/2 in. What is the rectangle’s perimeter?
Answer:
b. 7 4/5 in
Step-by-step explanation:
First, turn 1 2/5 and 2 1/2 into decimals which would be 1.4 and 2.5. Then, multiply 1.4 by 2 and 2.5 by 2 since you have to add up all the sides of the rectangle. Then, add the products to get the perimeter of 7.8 inches. (4/5 = 0.8).

Please help!!!!!!!! I will mark brainliest if right!!!! Explain
Answer:
They are not similar.
Step-by-step explanation:
The angles of a triangle add up to be 180°. If they were similar, the triangle angles would have to be 60°, 40°, and 80°. Because one of the angles is 81°, the triangles cannot be similar.
81° + 40° + 60° does not equal 180.
