Answer:

  (d)  -√((2+√2)/(2-√2))

Step-by-step explanation:

5π/8 is a 2nd-quadrant angle whose reference angle is greater than π/4. This means the tangent is negative with a magnitude greater than 1. The only reasonable choice is ...

  [tex]\displaystyle -\sqrt{\frac{2+\sqrt{2}}{2-\sqrt{2}}}[/tex]

Additional comment

This simplifies to -(1+√2). Your calculator can verify the choice for you.

Answer:

x = -4

Step-by-step explanation:

The axis of symmetry is the vertical line that makes a mirror image on the left and right for a vertical parabola

It goes through the vertex and is the x coordinate

x = -4

f + 6 = ?

Well, the answer can be pretty much any number. It all depends on what number f is. f is a variable, so you can plug in any number to replace f.

For example, if f was 5, this is what the equation would look like:

5 + 6 = 11

If f was -3, this is what the equation would look like:

-3 + 6 = 3

So, again, the answer can be anything. It depends on what f is.

Step-by-step explanation:

let the no of girls be x

ratio of boys to girls=4:7

4/7=16/x

do cross multiplication

7*16=x*4

112=4x

112/4=x

28=x

therefore there are 28 no of girls.

Answer:

<H = 40

Step-by-step explanation:

Complementary angles add to 90 degrees

2x+10 + x+20 = 90

Combine like terms

3x+30 = 90

Subtract 30

3x+30 -30 = 90-30

3x = 60

Divide by 3

3x/3 = 60/3

x = 20

<H = x+20 = 20+20 = 40

Answer:

A = 6x² + 97x + 391

Step-by-step explanation:

Given that,

The length of the shop, l = (3x+23)

The width of the shop, b = (2x+17)

The expression for the area of the shop is given by :

A = lb

Put all the values,

A = (3x+23) × (2x+17)

= 6x² +51x+46x +391

= 6x² + 97x + 391

Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.

Answer:

Step-by-step explanation:

take 30 degree as reference angle

using sin rule

sin 30=opposite/hypotenuse

1/2=x/10(do cross multiplication)

2*x=10*1

x=10/2

x=5

Answer:

5

Step-by-step explanation:

The sin is the opposite cathetus divided by the hypothenuse, and the sin30° = 0.5, so let's do an equality:

sin30° = x/10

0.5 = x/10

10•0.5 = x

x = 5

Step-by-step explanation:

Answer:

72 pints of the first type

18 pints of the second type

Step-by-step explanation:

See attachment for complete question

Given

[tex]x \to[/tex] first type

[tex]y \to[/tex] second type

Final volume = 90; So:

[tex]x + y = 90[/tex]

From the question, we understand that:

70% of x and 95% of y gives 75% of the fruit juice

This is represented as:

[tex]70\% * x + 95\% * y = 75\%* 90[/tex]

Make x the subject in [tex]x + y = 90[/tex]

[tex]x = 90 - y[/tex]

Substitute: [tex]x = 90 - y[/tex] in [tex]70\% * x + 95\% * y = 75\% * 90[/tex]

[tex]70\% * (90 - y) + 95\% * y = 75\% *90[/tex]

Express percentage as decimal

[tex]0.70 * (90 - y) + 0.95 * y = 0.75 * 90[/tex]

Open brackets

[tex]63 - 0.70y + 0.95y = 67.5[/tex]

Collect like terms

[tex]- 0.70y + 0.95y = 67.5 - 63[/tex]

[tex]0.25y = 4.5[/tex]

Divide both sides by 0.25

[tex]y = \frac{4.5}{0.25}[/tex]

[tex]y = 18[/tex]

Recall that: [tex]x = 90 - y[/tex]

[tex]x = 90 - 18[/tex]

[tex]x = 72[/tex]

Answer:

Perimeter you add up all the sides.  If it is a horizontal or vertical line, you just write those values for the side lengths.  For the slanted one, I would use pythagorean theorem to solve it.

Step-by-step explanation:

If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12.  Find the square root of the sum of a squared plus b squared.  That will tell you C.  Then add C to the other 3 sides and that will give you the perimeter.

Answer:

The answer is 3 for the above question

Answer:

x = 64 degree  , 2x = 128 degree

Step-by-step explanation:

2x = 128 (being alternate interior angles)

x = 128/2

x = 64 degree

2x

=2*64

=128 degree

The value of angle 2x is 128 and angle x is 64.

Lines on a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.

When two lines in a plane are stretched endlessly in both directions and do not cross, they are said to be parallel. If two straight lines have separate y-intercepts and equal slopes, they are said to be parallel. A few significant parallel line attributes that accurately describe their features are shown below.

given:

<1 = 2x

<2 = 128

now, using alternate interior angle

< 1 = <2

2x = 128

x= 128/2

x= 64

Hence, the value of 2x is 128 and x is 64.

#SPJ2

Answer:

Step-by-step explanation:

We have to use Pythagorean's Theorem twice here, first to find the length of the dotted line, which I will call h, and then again to find x. First we need to find h so we can use it to find x:

[tex](2\sqrt{5})^2=4^2+h^2[/tex] and

[tex]20=16+h^2[/tex] and

[tex]4=h^2[/tex] so

h = 2. Then again:

[tex]x^2=2^2+22^2[/tex] and

[tex]x^2=4+484[/tex] and

[tex]x^2=488[/tex] so

x = 2√122

Answer:

[tex]hypotenuse = 5 \: cm \\ height = 5 - 1 = 4 \: cm \\ base = \sqrt{ {5}^{2} - {4}^{2} } = \sqrt{9} = 3 \: cm[/tex]

Part A:

[tex]perimeter = 5 + 4 + 3 \\ = 12 \: cm[/tex]

Part B:

[tex]area = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 3 \times 4 \\ = 6 \: {cm}^{2} [/tex]

Answer:

128degrees

Step-by-step explanation:

Using the theorem that states that the angle at the centre is twice the angle at the circumference, hence;

<D = 180 - 116

<D = 64

<x = 2(<D)

<x = 2(64)

<x = 128

Hence the measure of <x is 128degrees

Answer:

Answer:

Therefore, the other side length of the Rectangle b = 4 (4/9)

Step-by-step explanation:

Although crucial information that area of the rectangle is missing we can assume it be 10 square units for understanding purposes.

Let the sides of the rectangle be a and b.

Given a = 2 1/4 units

a = 9/4 units

b=?

Area of a rectangle = product of its sides = a×b

⇒ a×b= 10

⇒ 9b/4 = 10

⇒ b= 40/9 = 4 (4/9)

Therefore, the other side length of the Rectangle b = 4 (4/9)

Answer:

x = 6/k

Step-by-step explanation:

kx + 12 = 3*kx

to make like terms on same side shift kx to right hand side . when u shift positive kx to other side it becomes negative

12 = 3kx - kx

12 = 2kx

shift 2 to left hand side when u shift multilication changes to division.

12/2 = kx

6 = kx

to find x u must shift k to other side . here also same since k and x are multilied when k shifts to others side it becomes divisor.

6/k = x
