Prove: (sin α + cos β)^2 + (cos β + sin α)(cos β − sin α) = 2 cos β(sin α + cos β)
Answers
The two terms on the left side both have a common factor of (sin(α) + cos(β)), so we can pull it out like so:
(sin(α) + cos(β))² + (cos(β) + sin(α)) (cos(β) - sin(α))
= (sin(α) + cos(β)) [(sin(α) + cos(β)) + (cos(β) - sin(α))]
= (sin(α) + cos(β)) (sin(α) + cos(β) + cos(β) - sin(α))
= 2 cos(β) (sin(α) + cos(β))

The equation of the line that is perpendicular to y = -5/2 x + 1 and passing through (10, 3) will be y = 2/5 x + 1.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The equation of the perpendicular line will be given as
y = mx + c
The given equation is y = -5/2 x + 1.
The slope of the line is -5/2.
Then the product of the slope of the perpendicular lines is a negative one.
-5/2 × m = - 1
m = 2/5
Then the equation will be
y = 2/5 x + c
Then the equation is passing through (10, 3). Then we have
3 = 2/5 × 10 + c
3 = 2 + c
c = 1
Then the equation is y = 2/5 x + 1.

Set C is the set of natural numbers less than 7.
Answers
Answer:
C = {1, 2, 3, 4, 5, 6}
C = {x ∈ N | x < 7}
Step-by-step explanation:
Hello!
Natural numbers are integers greater than 0 and not including it.
Lets list the natural numbers until 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Now, set C contains all of the natural numbers less than 7, so we select all of the numbers before 7 into our set.
C = {1, 2, 3, 4, 5, 6}The set contains numbers 1, 2, 3, 4, 5, and 6.

PLEASE HELP!!!!! IMA DESPRATE!!!!!! ach side of a telescope lens can be described by the equation f(x) = x2/58, where x is the width of the lens and f(x) is half its thickness.
If the lens is 2.9 inches wide, what is the total thickness (rounded to the nearest hundredth)?
Answers
Since the lens is 2.9 inches wide, the total thickness of the lens is 0.29 in
To answer the question, we need to know what equations are.
What are equations?Equations are mathematical expressions which show the relationship between two variables.
The total thickness of the lensSince f(x) = x²/58 describes half the thickness of the lens where x = width of lens.
So, the total thickness of the lens is y = 2f(x)
= 2 × x²/58
= x²/29
Since x = 2.9 in, substituting x into the equation, y, we have
y = x²/29
y = (2.9)²/2
y = 8.41/29
y 0.29 in
So, the total thickness of the lens is 0.29 in

Answers
Answer:
a) angle QRP is 92 degrees, side QR is 23 cm, angle RPQ is 47 degrees
b) angle EFD is 65 degrees, side FD is 22cm, side ED is 20cm
Step-by-step explanation:
a) in the first example, you know that u are given QR, PR, and angle PRQ, and u are asked to find triangle PQR,or the rest of the lengths.
step 1-u draw an example of the triangle, i will provide one for each at the bottom of this answer
step 2-lets find the sides first with the pythagorean theorem, which will mean 25²+x²=34². Pythagorean theorem is a²+b²=c²
step 3-after solving for x, x will be 23.04, which means the third side is 23 cm (after rounding).
step 4-now that we have all the sides, we can solve for the rest of the angles, by trigonometric ratios, we are gonna use sine for angle RPQ, sine is sin(the angle u want to find)=opposite side/hypotenuse.
step 5- so sin(RPQ)=25/34, and solve for RPQ on a calculator (i used math) and angle RPQ will equal 47.3 degrees.
step 6- just subtract the sum of both angles from 180 an the last angle will be 92 degrees.
b) u are given the measure of angles FED and EDF and the side length FE, we will solve for the last angle first then we will go for the side engths
step 1- we subtract the sum of the two angles we have from 180 and we will get the measure of angle EFD to be 65 degrees, now we have the angles and we want to find he sides.
step 2-we use sine of angle 31 degrees to find the hypotenuse, but it is opposite of sine since we want to find the side, not the angle, so we will use sin(31)=11.3/x, the sine equation is written like sin(the angle u have)=opposite/hypotenuse.
step 3- after solving for arc sine in a calculator, u will find side FD to be 22cm, and now to find the last side.
step 4-i will use the sine of angle 65 degrees to solve for side ED, it will be sin(65)=x/22, which will make side ED equal 20 cm in length.
ur welcome :)

Wite a differential equation in which y^2= 4(t + 1) is a solution.
Answers
Explanation:
The differential equation can be found by taking the derivative of y with respect to t of both sides of this equation.
Derivative of y^2 becomes 2y * dy/dt.
4(t+1) can be distributed to equal 4t + 4.
Derivative of 4t + 4 becomes 4.
Therefore, a possible differential equation is dy/dt * 2y = 4. Can check by separating and integrating.
