The required angle of obtuse angles are <BMD  ,<AMC  and <AME.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given:

The given figure is shown

<BMC=EMC=90°

According to given question we have

Angles between 90 and 180 degrees (90°< θ <180°) are known as obtuse angles.

Angles that are 90 degrees (θ = 90°) are right angles.

Angles that are 180 degrees (θ = 180°) are known as straight angles.

Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles.

<BMC=EMC=90° (right angles)

<BME =<AMD= 180°( straight angles)

<BMD=<AMC=<AME =90°< θ <180°  (obtuse angles )

Therefore, the required angle of obtuse angles are <BMD  ,<AMC  and <AME.

Answer:

y = -1/6x - 7/3

Step-by-step explanation:

slope = rise/run

(y2 - y1) / (x2 - x1)

ordered pairs: (-2,-2) and (4,-3)

-3 - (-2) = -1

4 - (-2) = 6

-1/6 = -1/6

m = -1/6

find b

take one ordered pair

y = mx + b

-3 = (-1/6)(4) + b

-3 = -4/6 + b

-3 + 4/6 = -2 2/6  

-2 2/6 = -14/6

-14/6 = -7/3

b = -7/3

Explanation:

Start at -1 on the x axis number line. Then move vertically until reaching the function curve. You should arrive at (-1,2). This tells us that g(-1) = 2. In other words, the input x = -1 leads to the output y = 2.

Follow similar steps to find that g(1) = -2

Therefore, g(-1)+g(1) = 2 + (-2) = 0

Solve the quadratic equation

  c² +16c+64 = 0

Step-by-step explanation:

Given that

             c² +16c+64 = 0

To find

So, according to the question

we have,

We can solve this quadratic equation by factorising method.

So, we have to convert it on factors,

        c² +16c+64 = 0

For getting it's factors, we have to divide 16c part in two parts,

So, we can write 16c = 8c + 8c,

        c² +16c+64 = 0

        c² +8c+ 8c+ 64 = 0

Now,

        c(c +8) + 8(c+ 8) = 0

                  (c+8)(c+8) = 0

                        (c+8)² = 0

 or,

                       (c + 8) = √0   (∵  √0  = 0)

                         c + 8 = 0

Now, we can say that

Answer:

1200 ml

Explanation:

Let x be the quantity ( in ml ) of b solution,

∵  solution a is 100 milliliters less of than solution  b.

So, the quantity of solution a = 100 - x,

Now, solution a has 13% alcohol,

∴ Alcohol in solution a = 13% of (100-x) =  = 0.13(x-100),

While solution b has 17% alcohol,

∴ Alcohol in solution b = 17% of x = 0.17x,

So, the quantity of alcohol in the mixture of a and b = 0.13(x-100) + 0.17x

= 0.13x - 13 + 0.17x

= 0.30x  - 13

According to the question,

Total quantity of alcohol in the mixture = 347 ml,

⇒ 0.30x  - 13 = 347

⇒ 0.30x = 347 + 13

⇒ 0.30x = 360

⇒ x =  = 1200

Hence, the quantity of solution b is 1200 ml.

Answer: The answer for this would y=-2x+b in slope form and y=-2x+3 in standard form.

Step-by-step explanation:

First we have to figure out what the slope is and you should this formula y2-y1/x2-x1 you plug in the coordinates and your equations should look like this -3-5/3-(-1)= -8/4 which simplified into -2. In standard form you put in the same equation but plug in the coordinates with the slope so it would look like this. -3=-2(3)+b and you would get 3 as b and then you substitute it in the equation again y=mx+b and it should like this in standard form y=-2x+3.

The complete paragraph is shown:

The complex number - 2 + i 8 has modulus of 2√17. When - 2 + i 8 is multiplied by 5, the modulus of the product of 10√17.

Multiplying a complex number by a real number is a scalar of a complex number. The quadrant location of the complex number and its product with the real number are the same.

In this problem we have a paragraph, in which we must fill the blanks with the results of operations with complex numbers. The modulus of a complex number is found by using the Pythagorean theorem:

r = √[(- 2)² + 8²]

r = √(4 + 64)

r = √68

r = 2√17

And the product between the real number and the complex number is done by distributive property:

5 · (- 2 + i 8)

5 · (- 2) + i (5 · 8)

- 10 + i 40, whose modulus is 10√17.

Graphically speaking, the scalar of a complex number remains in the same quadrant of the complex plane.

For the given graph:

And yes, it is a function.

For a given function y = f(x), the domain is the set of the inputs (possible values of x) and the range is the set of outputs (possible values of y).

To identify the domain we need to look at the x-axis (the horizontal one)

We can see in the left side that the first value is -2, whith a closed circle, meaning that the value belongs to the domain.

The right side is x = 0, with a open circle, which means that it does not belong to the domain.

Then the domain is D: [-2, 0)

Similarly, by looking at the y-axis (vertical axis) we can find the range which is:

R: [0, 2)

Finally, how to know if this is a function?

There is something called the "vertical line test". This test says that if you can't draw a vertical line that intersects the graph in two points or more, then it is a function.

The number of tracks on 4 CDs are 132.

Here, we are given that a CD holds 2t + 3 tracks.

Thus, the number tracks on 4 CDs will be given as-

4(2t + 3)

Simplifying the expression further, we get

(4 × 2 × t) + (3 x 4)

= 8t + 12

Therefore, the expression for the number of tracks on 4 CDs is 8t + 12

Now, if t = 15

Then, the number of tracks on 4 CDs can be found by substituting the value t = 15 in the expression (8t + 12)

= 8(15) + 12

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

Now the given equation is,

420 ÷ d = 30d = 15

Now if,

30d = 15

Then divide both the side by 30 we get,

30d/30 = 15/30

Solving we get,

d = 1/2

this is the required value of d

Now if,

420 ÷ d = 30d

So simplifying it we get,

420/d = 30d

multiplying both the side by d we get,

d*420/d = 30d*d

Solving we get,

30d^2 = 420

Dividing both the side by 30 we get,

30d^2/30 = 420/30

Solving we get,

d^2 = 14

Taking square root both the side we get,

√d^2 = √14

Solving we get,

d = ±√14
