Answer 1

Answer:

NM = [tex]\sf \sqrt{70}[/tex]

Step-by-step explanation:

Let NM = y

If KL is twice the length of NM, then KL = 2y

Given:

KM = 20NO = 7

As ΔKLN ~ ΔNOM

   KL : KM = NO : NM

[tex]\sf \implies 2y : 20 = 7 : y[/tex]

[tex]\sf \implies \dfrac{2y}{20}=\dfrac{7}{y}[/tex]

[tex]\sf \implies 2y \cdot y=7 \cdot 20[/tex]

[tex]\sf \implies 2y^2=140[/tex]

[tex]\sf \implies y^2=70[/tex]

[tex]\sf \implies y=\sqrt{70}[/tex]

As NM = y, then NM = [tex]\sf \sqrt{70}[/tex]

Answer 2

Answer:

NM = [tex]\sqrt{70}[/tex]

Step-by-step explanation:

Δ NMO and Δ KML are similar ( by the AA postulate )

Then the ratios of corresponding sides are in proportion, that is

[tex]\frac{NM}{KM}[/tex] = [tex]\frac{NO}{KL}[/tex] ( substitute values, noting KL = 2NM )

[tex]\frac{KM}{29}[/tex] = [tex]\frac{7}{2NM}[/tex] ( cross- multiply )

2 NM² = 140 ( divide both sides by 2 )

NM² = 70 ( take the square root of both sides )

NM = [tex]\sqrt{70}[/tex]

how would i find the area of this

Answers

Answer:

Your answer is 30 sq. yd

Step-by-step explanation:

To find the area of the rectangle:

l x w

6 x 4 = 24

To find area of triangle:

1/2(bh)

to find the base of the triangle you subtract 6 from 9:

9 - 6 = 3

So 1/2 (3 x 4)

1/2 (3 x 4)

1/2 (12)

12 / 2 = 6

Area of whole figure:

You will now add 6 + 24 = 30

So you have a rectangle and a triangle, first you’re are going to get the measurements of the rectangle which is 6,6,4,4 because every opposite side is equal, so the formula of the area of a rectangle is LW which is 6x4=24. And then get the area of the triangle, the sides of the triangle will be 3 as the base and 4 as the height, the formula of the area of a triangle is HB/2 which is 4x3/2=6. Last step you’ll add both of the areas together and get the total of the whole figure which is 24+6=30
30 Will be your final answer

Answers

Answer:

10 is the answer

Step-by-step explanation:

Let squares be x, triangles be y and circle be z

Now,

x³ = 27

so, x = 3

Now,

x * y * y * y = 24

or, 3 * y³ = 24

or, y³ = 24/3

so, y³ = 8

so, y = 2

Again,

x * y * z² = 96

or, 3 * 2 * z² = 96

or, 6z² = 96

or, z² = 96/6

so, z² = 16

so, z = 4

Now,

z + x*y = 4 + 3*2 = 4 + 6 = 10

it should be 55, 27 divided by 3 is 9, 24-9 is 15, 15 divided by 3 is 5, 96-9-5=82, 82 divided by 2 is 41 so 41+5+9=55

Given the circle below with tangent \overline{NO} NO and secant \overline{QPO} QPO ​ . If QP=9QP=9 and QO=14QO=14, find the length of \overline{NO} NO . Round to the nearest tenth if necessary. Q

Answers

Given that that the lengths of the parts of the secant are, QO = 14 and QP = 9, we have that the tangent, NO = 17.9

How can the length of the tangent be found?

The given parameters are;

Length of side, QP = 9

Length of QO = 14

Required;

The length of;

[tex] \overline{no}[/tex]

From the tangent and secant formula, we have;

[tex] { \overline{no}}^{2} = { \overline{qo}} \times ( { \overline{qp} \: + { \overline{qo}}})[/tex]

Which gives;

NO^2 = 14 × (9 + 14) = 322

NO = √(322) = 17.9

The length of the side NO = 17.9

What is the inverse of the trigonometric function in the graph? y = sinx y = cosx y = arcsinx y = arccosx

Answers

The inverse of the trigonometric function given in the graph is;

Option D; y = arc cosx

The graph is missing and so i have attached it.

To get the inverse of the trigonometric function, we need to first know what the trigonometric function is.

From the graph, we see that;

when x = 0, y = 1

when x = π, y = -1

when x = π/2, y = 0

Now, the equivalent of radian angle π when converted to degrees is; π = 180°

Thus; π/2 rad = 90°

Thus;

when x = 0°, y = 1

when x = 180°, y = -1

when x = 90°, y = 0

Now, let us look at the value of angle 0° for each trigonometric function sin, cos and tan.

sin 0 = 0

tan 0 = 0

cos 0 = 1

Let us try angle 90°

sin 90 = 1

cos 90 = 0

tan 90 = ∞

The only trigonometric function that corresponds with the coordinates of the graph is y = cos x.

The inverse of cos x is cos⁻¹x or arc cos x.

Zoe says an equilateral triangle is always an acute triangle, but an acute triangle is never an equilateral triangle. Which statement explains whether Zoe is correct or not

Answers

Answer:

Zoe is correct!

Step-by-step explanation:

The definition of an acute triangle is that all three angles are less than 90 degrees. An equilateral triangle has the angles 60, 60, and 60. All three are less than 90 degrees, so this means that an equilateral triangle is always an acute triangle.

However, that doesn't necessarily mean that an acute triangle is always an equilateral triangle.

Answer:

x = 20 degrees, angle ABC = 98 degrees

Step-by-step explanation:

The two inner angles sum up to 180 degrees. This is a general rule when you have two parallel lines and another line intersecting through both lines.

So angles ABC and DCB sum up to 180.

4x + 18 + 2x + 42 = 180

6x + 60 = 180

6x = 120

x = 20 degrees

Plugging this back in angle ABC,

4(20) + 18 = 98 degrees

Solution :-

3.14 cm²

Solution:

We know that:

Diameter of circle = 2 cmRadius = Diameter/2Area of circle = πr²

Finding the radius.

Radius = Diameter/2=> Radius = 2/2=> Radius = 1 cm

Finding the area.

Area of circle = πr²=> Area of circle = 3.14 x 1²=> Area of circle = 3.14 x 1 = 3.14 cm²

Which number is an irrational number?

Answers

Answer:

D. [tex]\sqrt[3]{16}[/tex]

Step-by-step explanation:

What is an irrational number?

  ❖ An irrational number is a number that cannot be written in fraction

      form. They're also non-terminating and non-repeating decimals.

Determing Irrational or Rational

A.

The square root of 100 is 10 because 10 × 10 = 100. 10 can be written as a fraction of 10/1, so it's rational.

B.

1/8 is already in fraction form, so it's rational.

C.

-2.2675 is a terminating decimal, so it's rational.

D.

The cube root of 16 is irrational because there is no exact number that multiplies itself 3x to get 16. Additionally, when you put the cube root of 16 in a calculator, you will get a mess of decimal digits, thus forming a non-repeating and non-terminating decimal.
