Answers

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

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.

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

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.

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

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

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.

The diameter of a circle is 2 centimeters. What is the circle's area?

Answers

Answer:

3.14 cm²

Step-by-step explanation:

Given :-

Diameter = 2 cm

To Find :-

Area

Formula Required :-

Area (circle) = πr²

Solving :-

Area = 3.14 x 1 x 1

= 3.14 x 1

= 3.14 cm²

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

The sum of interior angles of the given polygon is 900 degrees

How to calculate the sum of an interior angle of a polygon?

The formula used to calculate the sum of an interior angle of a polygon is expressed as:

Sum of interior angles = ( n − 2 ) × 180 ∘

n is the number of sides

The number of sides of the given polygon is 7, hence;

Sum of interior angles = (7 − 2 ) × 180 ∘

Sum of interior angles = 5 × 180 ∘

Sum of interior angles = 900 degrees

Answers

Answer:

The automobile's average speed is 53.33 mph.

Step-by-step explanation:

Since average speed equals total distance traveled divided by the time of the travel we have:

d = 320 mi the distance traveled

t = 6 hr the time of the travel

v = average speed

v = d/t

v = 320/6

v = 53.33 mph

Answer:

about 53 miles per hour

320/6 is 53.33 repeated

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
