HELP! Quick! Test! Will mark brainliest!

Part II: Using the variable you defined in Part I, write an expression to represent the
amount of money Sam will spend in one year (Sam's cost). (2 points)

Just need to put zero instead of y and solve the equation for find the value of x :

0 = 2 Cot ( x/4 )

Cot ( x/4 ) = 0

Cot ( x/4 ) = Cot ( π / 2 )

x / 4 = π / 2

x = 4 × π / 2

x = 2π

Thus the correct option is C .

The area of a circle is the radius squared x pi.

Area = r^2 x pi

R is the radius which is half the diameter.

Diameter = 102 inches

Radius = 102/2 = 51 inches

Area = 51^2 x pi

Area = 2,601pi inches^2 ( in terms of pi) or

Area = 8,167.14 inches^2

Area of circle is 8,167.14 cm ²

We have

diameter of circle = 102 cm

And we need to find area of circle,

So the formula we using is

Area of circle = π ×r ²

Here,

R denotes for Radius

π denotes for pi.

For finding area of circle we need to find radius

here we have diameter of circle = 102 cm and

We know that ,diameter is the double of radius it means radius is the half of diameter

So, radius of circle = 102/2 = 51 cm

Now Solve it

Area of circle = π × ( r ) ²

Substitute the value

Area of circle = 3.14 × ( 51cm )² .. [ using π = 3.14 ]

Multiply the values

Area of circle = 3.14 × ( 51 cm × 51cm) ..[( 51 ) ²= 51 × 51]

Area of circle = 3.14 × 2,601 cm².

Therefore , Area of circle is 8,167.14 cm ²

Answer:

1.632 ft cubic

Step-by-step explanation:

Volume = width * height * length

Volume = 0.6 * 0.8 * 3.4

Volume = 0.48 * 3.4

Volume = 1.632 ft cubic

Hope this helps.....

Have a good day ahead :)

Answer:

14.7%

Step-by-step explanation:

Being that there is 4 red, 2 blue, 6 green, 8 white, that means there is 20 marbles, with 8 success, 8/20. Since the marble is not replaced, that drops it to 7/19 for the second pull. Multiply these together and you get 14.7%.

(8/20)*(7/19)=.147

.147*100=14.7

Answer:

12 miles

Step-by-step explanation:

Alyssa takes part in the triathlon. She cycles 4/5 of the route, runs 1/8 of the route, and swims the rest of the way. She swims 0.9 miles. Find the total distance of the triathlon route.

Total distance Alyssa cycled and ran =

[tex]\frac{4}{5} + \frac{1}{8}[/tex]

[tex]\frac{32 + 5}{40}[/tex] = [tex]\frac{37}{40}[/tex]

Distance she swam =  1 - 37/40 = 3/40

3/40 of the distance is 0.9

the total distance = 40/3 x 0.9 = 12 miles

Answer:

Step-by-step explanation:

THe formula for calculating midpoint is expressed as;

M(X, Y) = {(x1+x2/2), y1+y2/2}

Given

Midpoint = (2, 5)

K = (8, 7)

Required

Coordinate of M

X = x1+x2/2

2 = 8+x2/2

4 = 8+x2

x2 = 4-8

x2 = -4

Similarly;

Y = y1+y2/2

5 = 7+y2/2

10 = 7+y2

y2 = 10-7

y2 = 3

Hence the coordidates of M is at (-4,3)

Answer:

The submarine moves 4 units right and 6 units down to get to its current position

Step-by-step explanation:

Given

[tex](x,y) \to (x + 4, y - 6)[/tex]

Required

Describe the movement of the submarine from the initial to the current position

The rule of translation is as follows:

[tex]x \to x + a[/tex] --- This implies right translation by a units

[tex]y \to y -b[/tex] --- This implies down translation by b units

So, we have:

[tex]x \to x + a[/tex]

[tex]x \to x + 4[/tex]

By comparison;

[tex]a =4[/tex]

[tex]y \to y -b[/tex]

[tex]y \to y - 6[/tex]

By comparison:

[tex]b = 6[/tex]

Hence, the submarine moves 4 units right and 6 units down to get to its current position

Answer:

92

Step-by-step explanation:

Since 92 is the answer, we need to factor out 92

Answer:

11. 26

12. 111

Step-by-step explanation:

_____________

Answer:

11:

since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=111

Answer:

4 /15

Step-by-step explanation:

From the number cube :

Count of Numbers greater than 4 = 16

Sample space of number cube = 20

P(number greater than 4) = 16 / 20 = 4/5

Word : ATTENTION

Count of letters in attention = 9

Count of T's in attention = 3

P(choosing T) = 3 / 9 = 1/3

P(greater than 4, then T) = 4/5 * 1/3 = 4 /15
