Step-by-step explanation:

[tex]\textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=77.62 \end{cases}\implies 77.62=2\pi r\implies \cfrac{77.62}{2\pi }=r \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2\qquad \qquad A=\pi \left( \cfrac{77.62}{2\pi } \right)^2\implies A=\cfrac{77.62^2}{4\pi }\implies A\approx 479.69[/tex]

Answer:

hello

f (2 ) = 6 et  f ( 0 ) = 3

( 3 - 6 ) / ( 0 - 2 ) = - 3/- 2 = 3/2

ax =  3 x /2

f (0) = 3  ⇔ b =  3

f (x) =  3 x /2 + 3

also  f ( 0) = 0 + 3 = 3  

sorry

y = ax + b

b = 3

since the line cuts the y-axis in 3

then for a ? which is the slope..

we take 2 points on the line (0 ; 3) and (2 ; 6)

we move 2 units to the left to go up 3 units

so a = 3/2

=> y = 3/2x + 3

or

f(x) = 3/2x + 3

Answer:

y = 45, x = 25

Step-by-step explanation:

Since 120 and (2y + 30) are vertical angles, (2y + 30) will equal 120.

2y + 30 = 120, Subtract by 30 on both sides

2y = 90, Divide 90 by 2

y = 45

Since 120 and (2x + 10) equal a straight line, it's a supplementary angle. Supplementary angles are equal to 180. Then you do 180 - 120, which equals 60. That means (2x + 10) equals 60.

2x + 10 = 60, Subtract 10 by both sides

2x = 50, Divide 50 by 2

x = 25

Answer:

6(2a-a+1)=24 =(3)

4+3(a+2)=16 =(2)

3a-2a-4=0 =(4)

2a+3(a+1)=8 =(1)

Step-by-step explanation:

6(2a-a+1) =24

6(2a-a+1) =2412a-6a+6 =24

6(2a-a+1) =2412a-6a+6 =246a =24-6

6(2a-a+1) =2412a-6a+6 =246a =24-66a= 18

6a/6= 18/6

a = 3

4+3(a+2)=16

4+3a+6=16

3a+10=16

3a=16-10

3a=6

3a/3=6/3

a=2

3a-2a-4=0

a-4=0

a=0+4

a=4

2a+3(a+1)=8

2a+3a+3=8

5a+3=8

5a=8-3

5a=5

5a/5=5/5

a=1

Answer: 60

Step-by-step explanation: first do 6-2 and multiple that by 180 after that your going to divide that by 6 u end up with 120 after subtract 180-120 = 60 .

Answer:

1.451 seconds.  Hurry.

Step-by-step explanation:

The position(height, h) of the foot ball will be given by the equation:

h = -32.2t^2 + 45t + 2.5

The term -32.2t^2 consists of the acceleration caused by gravity at Earth's surface ( -32 ft/sec^2) and the term +45t accounts for the initial velocity.  The + is assigned since the ball is moving vertically from ground.  The negative sign in -32t^2 is due to the acceleration being towards ground.  The term 2.5 accounts for the fact that the initial height of the ball is 2.5 feet above ground.

We can either calculate or graph with this function to find the time the ball spends in the air:

Calculate:

h = -32.2t^2 + 45t + 2.5

We need a value of t that would cause h to be 5.5 feet, the level it was caught:

5.5 = -32.2t^2 + 45t + 2.5

-32.2t^2 + 45t + 2.5 = 5.5

-32.2t^2 + 45t -3.0  = 0

Solve for t using the quadratic formula.  I get a value of 1.33 seconds.

Graph:

See the attached graph.  It confirms the 1.33 second value

Answer:

A=24

Step-by-step explanation:

First, we do the equations in the brackets(2x6) which is 12.

Before that, there is a 1/2 which means dividing whatever is inside the brackets by 2 which then becomes 6.

Then we x4 so the answer is 24.

a = 24

Step-by-step explanation:

[tex]\rm \: a = \frac{1}{2} (2 \times 6) \times 4 \\ \\ \rm a= \frac{1}{2} (12) \times 4 \\ \\ \rm a= \frac{12}{2} \times 4 \\ \\ \rm \: a = 6 \times 4 \\ \rm \: a = 24[/tex]

Answer:

Yes

Step-by-step explanation:

Yes. Explanations vary. Sample explanation: The weight itself doubles, so

any measurement of the weight using the same units will also double. We

can also see that by saying if the weight is x pounds, then double that weight

would be 2x pounds. The weight in kilograms will be x ÷ 2.2, and the double

weight will be or (2x) ÷ 2.2 2(x ÷ 2.2), which is also double.

Answer:

D

Step-by-step explanation:

They all move 1 unit up.

The mapping notation essentially tells you, what you do to each point to get the image point.

In this case (x,y)→(x,y+1) is telling you, for any given coordinate on the original, you add 1 to its y coordinate. Adding 1 to a y coordinate moves it up one unit.

Answer:

Theories used

Angles on a straight line will always add up to 180°

The sum of interior angles in a triangle is 180°

Question 7

a + 134° = 180°

⇒ a = 180° - 134°

⇒ a = 46°

b + 119° = 180°

⇒ b = 180° - 119°

⇒ b = 61°

a + b + c = 180°

⇒ 46° + 61° + c = 180°

⇒ c = 180° - 46° - 61°

⇒ c = 73°

Question 8

r + 126° = 180°

⇒ r = 180° - 126°

⇒ r = 54°

s + 145° = 180°

⇒ s = 180° - 145°

⇒ s = 35°

r + s + t = 180°

⇒ 54° + 35° + t = 180°

⇒ t = 180° - 54° - 35°

⇒ t = 91°

The interest in investing $6000 in a stock fund that is offering a constant annual interest of 5% is $300

Interest is the amount of money made from investing a particular amount of money over a period of time. It is given by:

I = PRT

I is interest, P is principal, R is rate and T is period

Donetta is investing $6000 in a stock fund that is offering a constant annual interest of 5%. Hence in one year:

I = 6000 * 5% * 1 year = 6000 * 0.05 * 1 = $300

The interest in investing $6000 in a stock fund that is offering a constant annual interest of 5% is $300

x=1400

Answer: y = 12.5x

Step-by-step explanation:

Because 250 bottles are filled every 20 minutes:

250/20=12.5

So, x=1, y=12.5

Hence, x=2 y=25

Because the number of bottles is directly proportional to the operation of the machine so:

12.5=a+b, 25.2a+b

a=12.5, b=0

Therefore, the equation is y = 12.5x

The Desmos graph of y = 12.5x is attached below
