The modified expression, x3(2x 5) – 4(2x 5), has two terms with a common factor of.

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

you do 82 - (21+37)

= 82 - 58

= 24

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.

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

sin 0 = 0

tan 0 = 0

cos 0 = 1

Let us try angle 90°

sin 90 = 1

cos 90 = 0

tan 90 = ∞

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

10x + 15y = 450

Step-by-step explanation:

A store sells bracelets for $10 and rings for $15.

Sold 30 items.

They counted the money they made $450.

x = bracelets

y = rings

10x + 15y = 450

The total length that Vulkan jumped on both occasions is 3 1/2 feet.

A fraction is a non integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.

First convert yard to feet: 1 yard = 3 feet

7/8 x 3 = 21/8 = 2 5/8

Now add the fractions together

2 5/8 + 2 7/8

2 (5 + 7) / 8 = 2 12/8 = 3 1/2 feet

The sample size of the actors is the number of actors Darrien selected

The sample size is 15

From the question, we understand that:

Darrien has 60 actors

This represents the population of the experiment.

Then he selected 15 of the actors, and 8 of them have previous acting experience.

The 15 actors he selected represents the sample of the experiment

Answer:

  (c)  (4.92, -0.91)

Step-by-step explanation:

The conversion shown in the attached uses the complex number features of the calculator, so the y-coordinate is shown as an imaginary value. Rounded to 2 decimal places the conversion is ...

  (r; θ) ⇔ (x, y)

  (5; 6.1) ⇔ (4.92, -0.91)

__

The correct answer choice can be made without the use of technology. The sum of the magnitudes of the values of x and y must not be less than r, eliminating the first two choices. The angle 6.1 radians is near the angle 6.28 radians (2π), so is almost 360°. It will be a 4th-quadrant angle, so its y-component will be negative (eliminating the last choice).

The only viable choice for polar coordinates of radius 5 and angle 6.1 radians is the third choice: (4.92, -0.91).

Additional comment

The angle given has no units, so we assume it is given in radians. A calculator can only give a proper answer if it is set to radians mode for angles.

The circumference of the circle is 106.76 km.

Circumference of a circle is defined as the total length of the boundary of the circle.

The concept is same as the perimeter for straight sided figures.

Given that,

The diameter of a circle is 34 kilometers.

Diameter of the circle = 34 kilometers

Radius of the circle = Half of diameter = 34 / 2 = 17 km

Circumference of the circle = 2πr, where r is the radius of the circle.

Circumference = 2π × 17

                         = 34π

                         = 106.76 km

Hence the circumference of the circle is 106.76 km.

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

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

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

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

Step-by-step explanation:

320/6 is 53.33 repeated

you divide 320/6 because you need to know how many miles you going in an hour
