What is the circumference and area of a circle with a radius of 4 meters? Round your answer to the nearest tenth.

Answer:

Step-by-step explanation:

In the image attached, you can observe that the angle we need to find is an acute angle of a right triangle, where its hypothenuse is 21 units long and its opposite leg is 16 units long.

Having these elements, we can use the sine trigonometric reason to find the angle.

[tex]sin(x)=\frac{opposite \ leg}{hypothenuse} =\frac{16}{21}\\ x=sin^{-1}(\frac{16}{21} ) \approx 49.63\°[/tex]

Therefore, the angle is 49.63°, approximately.

Answer:

(100,113) is on the graph of y = 1.2x -7

Step-by-step explanation:

y=1.2x−7

Substitute the point in and see if the equation is true

113 = 1.2 (100) -7

113 =120 - 7

113 = 113

This is true, so the point is on the graph

Answer:

5

Step-by-step explanation:

because..............

Using fraction, the sheets are a color other than red is 5.

Fraction is a "number are expressed as quotient, where numerator is divided by denominator".

According to the question,

Faith has 25 sheets of colored paper. She plans to make 15 of the cards out red paper.

[tex]\frac{15}{25}[/tex] =  [tex]\frac{3}{5}[/tex]

5 - 3 =2

Fraction 5 parts of sheets is equal to 25, 3 parts of sheet is equal to 15.

5 = 25

2 =  x

5 × 5 = 25

2 × 5  = 10

Hence, using fraction the number of sheets are a color other than red is 5.

Step-by-step explanation:

The correct calculation for the volume of the prism is 2 and one-half times 8 times 8 and one-half = 170 mm3

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of cube or cubes.

The volume will be calculated as:-

V   =   L  x  W  x  H

V   =  [tex]2\dfrac{1}2}[/tex]  x  8   x  [tex]8\dfrac{1}{2}[/tex]

V   =  ( 5/2)  x  8   x  ( 17/2 )

V   =  170 mm³

Therefore correct calculation for the volume of the prism is 2 and one-half times 8 times 8 and one-half = 170 mm3

Step-by-step explanation:

12x³-5x=2x²+x+6

y=12x³-5x

y=2x²+x+6

A system of equations is a collection of related equations

The system of equations that can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex] [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex]

The equation is given as:

[tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]

Split the above equation into 2, and set both equations to 0

[tex]12x^3 - 5x = 0[/tex]

[tex]2x ^2 + x + 6 = 0[/tex]

Replace the "0" with y, in both equations

[tex]12x^3 - 5x = y[/tex]

[tex]2x ^2 + x + 6 = y[/tex]

Rewrite the equations as:

[tex]y = 2x ^2 + x + 6[/tex]

[tex]y= 12x^3 - 5x[/tex]

Hence, [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex] can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]

Answer:

Yes, it is a right angle triangle

Step-by-step explanation:

Let leg lengths be y and z

Y = 2mm

Z = 2.1mm

Let x represent hypothenus

X = 2.9mm

To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)

x² = y² + z²

x² = 2² + 2.1²

x² = 4 + 4.41

x² = 8.41

Take the square root of both sides

x = √(8.41)

x = 2.9mm

Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle

Answer:

x =  ±sqrt(2)

Step-by-step explanation:

It is not a function if the same input goes to 2 different  outputs

x^2 +3 =5  would cause the same input to go to 2 different outputs

Subtract 3 from each side

x^2 +3-3 =5-3

x^2 = 2

Take the square root of each side

sqrt(x^2) = ±sqrt(2)

x =  ±sqrt(2)

Answer:

x = sqrt(2), -sqrt(2)

Step-by-step explanation:

For a function, there cannot be multiple outputs for the same input, therefore x²+3 should not be 5

x² + 3 = 5

x² = 2

x = +/- sqrt(2)
