Find the complementary angles of the following.
​

Answer:

j = 0  or j = 30

Step-by-step explanation:

j² - 30j = 0

Factorise j out of both terms on the left side.

j (j-30) = 0

Apply zero product rule.

j = 0  or j-30 = 0

Find the value of j.

j = 0  or j = 30

Answer:

Therefore, option A,B and C cannot be the angles of triangles.

Step-by-step explanation:

Given that total angles in a triangle is 180° so you have to add up all the angles :

Option A,

45° + 45° + 45° = 135° (Not a triangle)

Option B,

60° + 75° + 35° = 170° (Not a triangle)

Option C,

60.5° + 59.5° + 59° = 179° (Not a triangle)

Option C,

65° + 60° + 55° = 180° (It is triangle)

Answer:

The value of the expression when i is 1 is equals to 5.

Step-by-step explanation:

We are given the following expression:

[tex]2 + 3^{i}[/tex]

Evaluate the expression when i is 1.

We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So

[tex]2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5[/tex]

The value of the expression when i is 1 is equals to 5.

Step-by-step explanation:

[tex] - 1 \leqslant x \leqslant 6[/tex]

The domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a given a graph of a function in the picture.

As we can see, the at point x = -1 graph starts, and it has dark dot which means function values exist at x = -1.

Similarly, at x = 6 the function value exist.

The domain of the function:

-1 ≤ x ≤ 6

Thus, the domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.

Answer:

$8645.73

Step-by-step explanation:

Using the compound interest formula :

A = P(1 + r/n)^nt

A = final amount = 18000

r = rate = 6.5% = 0.065

n = number of compounding tines per period, biannually, once in 2 years = 0.5

18000 = P(1 + 0.065/0.5)^(0.5*12)

18000 = P(1 + 0.13)^6

18000 = P(2.081951752609)

18000 / 2.081951752609 = P

= 8645.7334

= $8645.73

[tex]\Huge\boxed{D}[/tex]

Step-by-step explanation:

Hello There!

To find the answer we want to find the trigonometric ratio for each answer choice

important note;

[tex]sin =\frac{opposite}{hypotenuse} \\\\cos=\frac{adjacent}{hypotenuse} \\\\tan=\frac{opposite}{adjacent}[/tex]

for A,

the opposite of angle X is  12 and the adjacent of angle x is 5

so [tex]tanX=\frac{12}{5}[/tex] therefore A is not the answer

for B,

the adjacent of angle x is 5 and the hypotenuse is 13

so [tex]cosX=\frac{5}{13}[/tex] therefore B is not the answer

for C,

the opposite of angle W is 5 and the adjacent of angle W is 12

so [tex]tanW=\frac{5}{12}[/tex] therefore C is not your answer

for D,

the adjacent of angle W is 12 and the hypotenuse is 13

so [tex]cosW=\frac{12}{13}[/tex] therefore D is your answer

Therefore , the solution of the given problem of triangle comes out to be triangle C has the largest area 4.5 square unit.

Because a triangular has two or more extra parts, it is a polygon. It's shape is a simple rectangular. The only three edges that distinguish a triangle from just a triangle are A, B, and C. A singular area rather than a cube is produced by Euclidean geometry when the edges are not perfectly collinear. A shape is referred to as triangular if it has three sides and three angles. An angle is the point where a quadrilateral's three sides meet. A triangle's sides add up to 180 degrees.

Here,

The largest triangle ,

area wise is:

Triangle C area is:

=> 1/2 *  b * h

=> 1/2 * 3*3

=> 9/2

=> 4.5 square unit

which is the largest area as all the other triangles have 4 square unit area.

Answer:

29.8%

Step-by-step explanation:

1.30 × 800 = £1040  

25% of 800 = 200

800 - 200 = 600 poppy lapel pins given to the charity  

70% of 600 = 420

420 × 2.50 = £1050

30% of 600 = 180

180÷3 = 60  

60 × 5.00 = £300  

[tex]\frac{1050+300-1040}{1040}[/tex] = 29.8076923

= 29.8% to one decimal place

The company should make a percentage profit of approximately 29.8%.

Given that a company makes Poppy Lapel Pins.

Each of them costs £1.30 to make.

In October 800 lapel pins were made from which 25% were given to charities,

The rest are sold in two formats:

70% of them at £2.50 each

30% of them at £5.00 for 3.

We need to find the percentage profit the company should make.

To calculate the percentage profit, we first need to determine the total cost of manufacturing the lapel pins and the total revenue generated from their sales.

Total Cost:

Cost per lapel pin = £1.30

Number of lapel pins manufactured = 800

Total cost = £1.30 × 800 = £1040

Total Revenue:

Number of lapel pins given to charities = 25% of 800 = 0.25 × 800 = 200

Number of lapel pins available for sale = 800 - 200 = 600

Format 1:

70% of lapel pins sold at £2.50 each:

Number of lapel pins = 0.70 × 600 = 420

Revenue from this format = £2.50 × 420 = £1050

Format 2:

30% of lapel pins sold at £5.00 for 3:

Number of lapel pins = 0.30 × 600 = 180

Revenue from this format = (£5.00 ÷ 3) × 180 = £300

Total Revenue = Revenue from Format 1 + Revenue from Format 2 = £1050 + £300 = £1350

Profit:

Profit = Total Revenue - Total Cost = £1350 - £1040 = £310

Percentage Profit:

Percentage Profit = (Profit ÷ Total Cost) × 100

Percentage Profit = (£310 ÷ £1040) × 100 ≈ 29.8%

Therefore, the company should make a percentage profit of approximately 29.8%.

Answer:

The series of transformations that apply are a vertical compression by a factor of 2 and a translation of 4 units down.

Step-by-step explanation:

In a slope-intercept function, the coefficient of the variable determines whether the graph opens up or down, as well as the amount it stretches. If a function's coefficient is greater than 1, as the value of the coefficient increases, the function becomes more vertically compressed. If a function's coefficient is less than 1 but greater than 0, as the coefficient gradually approaches 0, the function becomes more vertically stretched. Since the function's coefficient went from 1 to 2, that means the graph of the function is being vertically compressed by a factor of 2. A slope-intercept function's constant is the graph's y-intercept since the y-value would be that when x is equal to 0. Since the constant went from 0 to -4, that means the graph of the function has been translated down 4 units. So the correct choices would be a vertical compression by a factor of 2, and a translation of 4 units down.
