The equation 4sin^2x-3=0 has a solution of x=π/3,2π/3,4π/3,5π/3.

What is equation?

An equation is basically a relationship between two variables in equal to form. In an equation each variable must have a solution or value.

How to solve an equation?

The equation given as 4sin²x-3=0

We have to first find the value of x in the equation itself which is 4sin²x=3

sin²x=3/4

sinx=√3/2 or -√3/2

x=π/3, 2π/3, 4π/3, or 5π/3.

In a rhombus MPKN with an obtuse angle K the diagonals intersect each other at point E. The measure of one of the angles of a ∆PKE is equal 16°. Find the measures of all angles of ∆PKE and ΔPMN.

Answers

The rhombus has a couple of very interesting properties. The first is that the diagonals meet at 90o angles.

The second is that all the sides are congruent. That's actually the key to the problem (or one of them.

The third is that the diagonals are line segments that bisect the angles where the vertex of the angle is.

So just to make sure you understand what that last statement means <PKM = <NKM
K is the vertex of angle PKN

Now the really heavy duty stuff about your question.
Given
K is obtuse. Therefore <PKM can't be 16o because MKN would also have to be 16 degrees and together they don't add up to anything over 90o.
So the 16o angle is at <EPK

Remember that the diagonals meet at right angles. <PEK = 90o

Finally all triangles have 180o
< PKE = 180 - 16 - 90 = 74. So to review
<PKE = 74o
<EPK = 16o
<PEK = 90o That's one half the problem.

Moving on to triangle PMN
By the properties of parallel lines and a rhombus and isosceles triangles, that since PKN is bisected (rhombus property) Then PKN = 2* PKM =2*74 = 148o
The angle opposite <PKN is equal to <PKN so <PMN = <PKN
Since PKN = 148 then PMN = 148
Since KPN = 16o then PMN = 16o
Since triangle <PMN is isosceles <PNM = 16o

Summing up
PMN = 148o
MPN = 16o
MNP = 16o

That's both triangles solved. This is a really nice little problem. If you google properties of a rhombus, you will find all the properties I have used proven.

Answer:

m∠KEP = 90°

m∠EKP = 74°

m∠EPK = 16°

m∠N PM= 16°

m∠MNP = 16

m∠M = 148°

To find the value of ax + b, we need to isolate that expression on one side of the equation.

Starting with:

9ax + 9b - 6 = 21

We can add 6 to both sides:

9ax + 9b = 27

Then, we can factor out 9 from the left-hand side:

9(ax + b) = 27

Dividing both sides by 9, we get:

ax + b = 3

Therefore,

Five hummingbirds drink 7.5 ounces of sugar water a day. How much sugar water is needed for 14 hummingbirds?

Answers

First, divide 7.5 by 5 to find out how much sugar water is needed for each bird.
Each bird needs 1.5 ounces per day.
Then just multiply that by 14 to get 15.5 ounces of sugar water.
Hope this helps!

Since 5 hummingbirds drink 7.5 ounces, we have to figure out how many ounces goes to only one.

You should divide 7.5 by 5, and that equals 1.5

Then you're going to multiply 1.5 by 14 because there are 14 hummingbirds

1.5 * 14 = 21

21 ounces of sugar water is needed for 14 hummingbirds.

Answer:

Inverse of y = [tex]f^{-1}(x)[/tex] = [tex]\sqrt{100 -x}[/tex].

Step-by-step explanation:

Given : f(x) = y = 100 - x²

To find : Find inverse.

Solution : We have given that :

f(x) = y = 100 - x²

Step1) : Replace every x with a y and replace every y with an x .

x = 100 - y².

Step 2): Solve for y

On subtracting 100 from both sides

x - 100 = -y²

On multiplying both side by -1

100 -x = y²

Taking square root both sides and switching sides

y = ± [tex]\sqrt{100-x}[/tex].

Step3 ) : Replace y with [tex]f^{-1}(x)[/tex].

[tex]f^{-1}(x)[/tex] = ± [tex]\sqrt{100-x}[/tex].

Therefore, inverse of y = [tex]f^{-1}(x)[/tex] = ± [tex]\sqrt{100-x}[/tex].

a triangle has an area of 54 m2 and a height of 9m how long is the base of the triangle entered your answer in the box

Answers

Answer:
base of the triangle = 12 m

Explanation:
Area of the triangle = 1/2 * base * height
We are given that:
area = 54 m^2
height = 9 m

Substitute in the equation to get the base as follows:
Area of the triangle = 1/2 * base * height
54 = 1/2 * base * 9
108 = 9*base
base = 12 m

Hope this helps :)

The first thing you should know to solve this problem is that the definition of the area of the triangle is:
A =(1/2)* b * h
Where,
b: base
h: height.
Clearing the base we have:
b = 2*A / h
Substituting the values
b = 2*(54) / (9) = 12 m

For what value of xis the square of the binomial 3x+1 is 9 times greater than the square of the binomial x–2?

Answers

The information tells us that (3x+1)²=9(x-2)², so this means that we must now solve this equation to find x.
First, we expand the parentheses on both sides using FOIL (Firsts, Outers, Inners, Lasts) :
(3x+1)(3x+1)=9(x-2)(x-2)
9x²+3x+3x+1=9(x²-2x-2x+4
Simplify:
9x²+6x+1=9(x²-4x+4)
Now expand the RHS (right-hand side) expression - multiply all the terms inside the parentheses by 9:
9x²+6x+1=9x²-36x+36
Now solve as you normally would to isolate x. Start off by subtracting 9x² on both sides:
6x+1=-36x+36
Add 36x on both sides:
42x+1=36
Minus 1 on both sides:
42x=35
Divide both sides by 42:
[tex]x= \frac{35}{42} [/tex]
which simplifies to
[tex]x= \frac{5}{6} [/tex]
I double checked this by substituting x back into the question and it worked, you can try doing this too for verification.

Final answer:

The value of x for which the square of the binomial 3x+1 is 9 times greater than the square of the binomial x−2 is obtained by equating (3x + 1)² to 9(x − 2)², which simplifies and solves to x = 5/6.

Explanation:

To find the value of x for which the square of the binomial 3x+1 is 9 times greater than the square of the binomial x−2, we need to formulate and solve an equation based on the given conditions:

(3x + 1)² = 9(x − 2)²

Expanding both sides gives us:

9x² + 6x + 1 = 9x² − 36x + 36

Now, by simplifying and solving for x, we find:

42x = 35

x = 35 / 42

x = 5 / 6

Therefore, the value of x is 5/6.

Answer: The rate of decay is 93.3%.

Step-by-step explanation:

Since we have given that

The exponential function is given by

[tex]n(x)=7(0.067)^x[/tex]

As we know the general equation of exponential function that is given by

[tex]n(x)=a(1-b)^x[/tex]

Here, a denotes the initial value

1-b denotes the rate of decay.

So, On comparing both the equations, we get that

[tex]1-b=0.067\\\\b=1-0.067\\\\b=0.933=0.933\times 100=93.3\%[/tex]

Hence, the rate of decay is 93.3%.

The diagonals BF and CE divide the hexagon ABCDEF into two equilateral triangles and a square. Find the perimeter of the hexagon if BF = 3 cm. Answer: P = cm

Answers

18 cm
Because all the sides are the same size

Answer: The perimeter of the hexagon is 18 cm.

Step-by-step explanation: As given in the question, hexagon is shown in the attached figure.

The diagonals g and h divides the hexagon into two two equilateral triangles and one square .

Also, length of diagonal g = 3 cm.

We are to find the perimeter of hexagon.

We know that all the sides of a square are equal, so we have

length of b = length of h = length of e = length of g = 3 cm.

Since the two triangles are equilateral, so all their sides will be equal.

That is, length of a = length of f = length of g =length of c =length of d = length of h = 3 cm.

We know that the perimeter of a polygon is equal to the sum of the lengths of its sides.

Therefore, the perimeter of hexagon is given by

P = a + b + c + d + e + f = 3 + 3 + 3 + 3 + 3 + 3 = 18 cm.

Thus, the perimeter of the hexagon is 18 cm.

The diagonal of rectangle ABCD measures 2 inches in length What is the length of line segment AB?

Answers

Hi. I have found the diagram for this problem through other resources and I have it attached.

In the diagram, we already have the angles given so we just need to find the length of one side. Let's first find the length of segment CD since we are given the angles on that side of the rectangle.

We can find its length by applying SOHCAHTOA. We can either use the 60 or 30-degree angle but for this solution let's make use of 60 degrees. From SOHCAHTOA we know that sine of 60 is equal to the length opposite it (CD) over the hypotenuse which is the diagonal that is equal to 2 inches. Knowing this we can solve for CD:

[tex]sin(60)= \frac{CD}{2} [/tex]
[tex] \frac{ \sqrt{3}}{2}= \frac{CD}{2} [/tex]
[tex] \sqrt{3}=CD [/tex]

We are told that the rectangle was scaled by a factor of 7.

What this means is that if the length and width are x and y respectively, then the new scaled measurements will be;

Now,for us to scale back to the original size, all we need to do is to divide the new scale measurements by a factor of 7.

This means the original size will be;

Length = 7x × 1/7

Width = 7y × 1/7
