Answer 1

Answer:

1.  0.9925  (4 d.p.)

2.  17°

3.  67°

Step-by-step explanation:

Question 2

⇒ sin 83° = 0.9925461516...

⇒ sin 83° = 0.9925 (4 d.p.)

Question 3

[tex]\sf \implies \sin X=0.2923[/tex]

[tex]\sf \implies X=\sin^{-1}(0.2923)[/tex]

[tex]\implies \sf X=16.99570395...^{\circ}[/tex]

[tex]\implies \sf X=17^{\circ}\:\:(nearest\:degree)[/tex]

Question 4

Sine Ratio

[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]

where:

[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)

From inspection of the triangle:

[tex]\theta[/tex] = WO = OS = 24H = OW = 26

Substitute the values into the formula and solve for W:

[tex]\implies \sf \sin(W)=\dfrac{24}{26}[/tex]

[tex]\implies \sf W= \sin^{-1}\left(\dfrac{24}{26}\right)[/tex]

[tex]\implies \sf W=67.38013505...^{\circ}[/tex]

[tex]\implies \sf W=67^{\circ}\:\:(nearest\:degree)[/tex]

Step-by-step explanation:

Use the equation:

x + (x × P%) = y

x(1 + P%) = y

x = 1864/(1 + 17%)

x = 1864/(1 + 0.17(17%))

x = 1864/1.17

a translation 3 units up and 1 unit left and then a 180° rotation about the origin
a 90 degree clockwise rotation about the origin and then a reflection over the Y axis
a 90° counterclockwise rotation about the origin and then a reflection over the X axis
A translation through you to down and one unit right and then I 108° rotation about the origin

Answers

The correct transformation is a rotation of 180° around the origin followed by a translation of 3 units up and 1 unit to the left.

Which transformation is used to get A'B'C'?

To analyze this we can only follow one of the vertices of the triangle.

Let's follow A.

A starts at (3, 4). If we apply a rotation of 180° about the origin, we end up in the third quadrant in the coordinates:

(-3, -4)

Now if you look at A', you can see that the coordinates are:

A' = (-4, -1)

To go from (-3, -4) to (-4, -1), we move one unit to the left and 3 units up.

Then the complete transformation is:

A rotation of 180° around the origin, followed by a translation of 3 units up and 1 unit to the left.

Assume that an economy has 1,000 workers, each working 2,500 hours per year. if the average real output per worker-hour is $20, then total output, or real gdp, will be

Answers

Answer:

  $50,000,000

Step-by-step explanation:

You want to know the total output (real gdp) of 1000 workers, each working 2500 hours producing real output of $20 per hour.

GDP

The output, called "gross domestic product" or GDP, is the total output of all workers for the hours they work:

  (1000 worker) × (2500 hours/worker) × ($20/hour) = $50,000,000

The GDP will be $50,000,000 or 50 million dollars.

Using proportional reasoning, about how many students out of the 2,000 would you expect to select an orange as their favorite fruit?

Answers

Answer:

almost 567 students

Step-by-step explanation:

all fruits = 23+18+34+27+18 = 120

possibility of selecting an orange as favourite fruits by one student = 34/120 = 17/60

possibility of selecting an orange as favourite fruits by 2000 students = 17/60×2000 =1700/3 = 566.6666...=567 students

1. Probability of getting (soup, burger, coke)

2. Probability of getting (fries, burger, any drink)

Answers

Answer:

1/12; 1/6

1. the chance of getting soup is 1/3, the chance of getting a burger is 1/2, and the chance of getting coke is 1/2, multiply these chances to get (1/3) *(1/2) * (1/2) = 1/12

2. the chance of getting fries is 1/3, the chance of getting a burger is 1/2, and the chance of getting any drink is 1, multiply these chances to get (1/3) * (1/2) * 1 = 1/6

x = 200° (arc measure = central angle measure)The inscribed angle y is half of the arc length xy = 1/2xy = 1/2(200°)y = 100°

Q10

x + 112 = 180x = 68°y + 81 = 180y = 99°

Answer:

9.  x = 200  and  y = 100

10.  x = 68  and  y = 99

Step-by-step explanation:

Question 9

The measure of an arc is the measure of its central angle.

⇒ x = 200

This is a non-cyclic quadrilateral as not all its vertices touch the circumference of the circle.

The angle at the center is twice the angle at the circumference.

⇒ y = 200 ÷ 2

⇒ y = 100

Question 10

This is a cyclic quadrilateral as all its vertices touch the circumference of the circle.  

The opposite angles in a cyclic quadrilateral add up to 180°.

⇒ x + 112 = 180

⇒ x = 68

⇒ y + 81 = 180

⇒ y = 99

What is the y-intercept of the function f(x) = -2/-9x+1/3?

Answers

Answer:

b = 1/3

Step-by-step explanation:

The general structure of equations in slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept.

The given equation is already in slope-intercept form. In other words, you have already been given "m" and "b". Therefore, the value which corresponds with the y-intercept is (1/3).

f(x) = mx + b

f(x) = -(2/9)x + 1/3

From the question, we are to determine the value of y in the given logarithmic equation

The given equation is

[tex]log_{4}64=y[/tex]

By applying one of the laws of logarithm, we get

[tex]64 = 4^{y}[/tex]

Now, express 64 in index form,

[tex]4^{3} = 4^{y}[/tex]

Since the bases are equal, we can equal the powers to get

3 = y

∴ y = 3

Hence, the value of y in the given logarithmic equation is 3. The correct option is C. 3

What is an equation of a circle?

A circle can be characterized by its center's location and its radius' length. Let the center of the considered circle be at (h,k) coordinate and the radius of the circle be 'r' units. Then, the equation of that circle would be:

(x-h)² + (y-k)² = r²

The given graph is the graph of a circle that has its origin at (0,0) and has a radius of 4 units, therefore, the equation will be,

(x-0)² + (y-0)² = 4²

x² + y² = 16

Multiply both the sides of the equation by 2,

2x² + 2y² = 32

Hence, the correct option is A.
