Step-by-step explanation:

It's the fourth option, 1 - sinθ/cscθ. This is due to the cancellation of cosθ in the numerator:

1 - (sinθ/cosθ × cosθ)/cscθ = 1 - sinθ/cscθ

Answer:

[tex]\sqrt{32}[/tex] or 4[tex]\sqrt{2}[/tex] simplified

Step-by-step explanation:

4² + 4² = c²

c² = 32

c = [tex]\sqrt{32}[/tex]

c = [tex]\sqrt{16}[/tex][tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex]

Answer:

Option (1)

Step-by-step explanation:

Coordinates of the vertices of ΔPQR,

P → (2, 5)

Q → (6, 2)

R → (2, 2)

Now vertices of the transformed triangle,

P' → (2, -5)

Q' → (6, -2)

R' → (2, -2)

If we compare P and P' relation between their coordinates is,

P(2, 5) → P'(2, -5)

(x, y) → (x, -y)

Which reveals that triangle PQR has been reflected across x-axis to form the image triangle P'Q'R'.

Option (1) is the answer.

A resistor is a two-terminal passive electrical component. The correct option is A.

A resistor is a two-terminal passive electrical component that uses electrical resistance as a circuit element.

The voltage of a circuit decreases when a resistor is present in the circuit, therefore, the options with the light bulbs are not the correct options. Since a 9V battery has more voltage than a 1.5V battery.

Therefore, the correct option is A.

Answer: 6/5

Step-by-step explanation:

Group the variables together on one side and the numbers together on the other.

(5/6)x = 1

x = 6/5

Answer:

x = 6/5

Step-by-step explanation:

1x/2 + 1x/3 = 4-3

3x/6 + 2x/6 = 1

5x/6 = 1

5x = 6

x = 6/5

Answer:

-6r+6

Step-by-step explanation:

Given data

We are given the expression

8-(6r+2)

let us expand it by opening the bracket

=8-6r-2

collect like terms

=8-2-6r

=6-6r

rearrange

=-6r+6

Missing part of the question

Determine the number of handshakes, i, that will occur for each number of people, n, in a particular room. (people)

Answer:

[tex]S_n = \frac{n}{2}(n - 1)[/tex]

Step-by-step explanation:

Given

For 5 people

[tex]\begin{array}{cc}{People} & {Handshakes} & {5} & {4} & {4} & {3} & {3} & {2} & {2} & {1} & {1} & {0} &{Total} & {10} \ \end{array}[/tex]

Using the given instance of 5 people, the number of handshakes can be represented as:

[tex](n - 1) + (n - 2) + (n - 3) + ........ + 3 + 2 + 1 + 0[/tex]

The above sequence is an arithmetic sequence and the total number of handshakes is the sum of n terms of the sequence.

[tex]S_n = \frac{n}{2}{(T_1 + T_n})[/tex]

Where

[tex]T_1 = n - 1[/tex] --- The first term

[tex]T_n = 0[/tex] --- The last term

So:

[tex]S_n = \frac{n}{2}(n - 1 + 0)[/tex]

[tex]S_n = \frac{n}{2}(n - 1)[/tex]

Answer:

A. Rectangle

Step-by-step explanation:

Shown in the attachment are the four points graphed on a coordinate plane.

We can see that the opposite sides are parallel to each other and have the same length.

The answer cannot be B. Square because the side lengths of this quadrilateral are not all equal to each other.

The answer cannot be C. Rhombus because of the same reason as above.

The answer cannot be D. Trapezoid because the bases of the quadrilateral are not of different lengths.

Therefore, the answer must be A. Rectangle since the angles are 90° angles, and the opposite sides are parallel and equal.

180 + 135 = 315.

Answer:

∠ B ≈ 51.06°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{7}{9}[/tex] , then

∠ B = [tex]sin^{-1}[/tex] ([tex]\frac{7}{9}[/tex] ) ≈ 51.06° ( to the nearest hundredth )

Answer:

40%

Step-by-step explanation:

Graphs such as line and tape diagrams can be used to represent equations.

Diagram (a)

In this diagram, all the x boxes (5 boxes) are shaded, while all the y boxes (3) are shaded.

So, the equation is:

[tex]y = \frac{3}{5}x[/tex]

Express as decimal

[tex]y = 0.6x[/tex]

The ratio (0.6) is less than 1.

So, it represents a decrement.

And the decrement (d) is:

[tex]d = 1 - 0.6[/tex]

[tex]d =0.4[/tex]

Diagram (b)

In this diagram, all the x boxes (6 boxes) are shaded, while part of  the y boxes (6 of the 11) are shaded.

So, the equation is:

[tex]y = \frac{11}{6}x[/tex]

Express as decimal

[tex]y = 1.83x[/tex]

The ratio (1.83) is greater than 1.

So, it represents an increment.

And the increment (d) is:

[tex]d = 1.83 - 1[/tex]

[tex]d = 0.83[/tex]

Answer:576

Step-by-step explanation:

The 3 pounds of tomato cost will cost £4.5.

Pound and lbs. are practically synonyms for one another. The popular shorthand used to denote pounds is "lbs," which stands for libra. The pound is the real unit of measurement.

The cost of 7 lbs of tomatoes is £10.50.

then, the cost of 1 lbs of tomatoes is,

10.50/7 = 1.5

The cost of 1 lbs of tomatoes is 1.5 lbs.

Since, 1 lbs = 1 pound

Thus, the total cost of 3 pounds of tomatoes is,

3×1.5 = 4.5

Therefore, the  3 pounds of tomatoes will cost £4.5.
