Step-by-step explanation:

To find an area of a circle its with the formula...

A = π [tex]r^{2}[/tex]

But since the diameter is given, and not the radius we need to divide the diameter by 2 (since half the diameter gives you the radius)

And the only one there that divides the diameter with the correct formula is the last one

Answer: There are 70 outcomes.

Step-by-step explanation:

The number of combinations for n things if r thing s have been chosen ( repetition is allowed) = [tex]C(n+r-1, n-1)[/tex]

Here , n= 5 , r= 4

The possible outcomes = [tex]C(5+4-1, 5-1)= C(8,4)[/tex]

As [tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]

So, The possible outcomes = [tex]\dfrac{8!}{4!(8-4)!}[/tex]

[tex]=\dfrac{8\times7\times6\times5\times4!}{4\times3\times2\times1\times4!}\\\\=70[/tex]

Hence, there are 70 outcomes.

Answer:

B. h(x) = 4x² - 4x + 11

Step-by-step explanation:

Given:

f(x) = 5x² - 2x + 1

g(x) = x² + 2x - 10

Required:

h(x) = f(x) - g(x)

Solution:

h(x) = (5x² - 2x + 1) - (x² + 2x - 10)

= 5x² - 2x + 1 - x² - 2x + 10 (distributive property)

Collect like terms

= 5x² - x² - 2x - 2x + 1 + 10

h(x) = 4x² - 4x + 11

Answer:

who wins four tosses first is the winner.

possible cases-7 tosses, 6 tosses, 5 tosses, 4 tosses

We get cases of Win of Head first-4 tosses

All 4 must be Head

Number of ways = 1

5 tosses-5th must be Head  

there are 3 Head   out of 4  in  ⁴C₃ = 4 Ways

6 tosses-6th must be Head  

there are 3 Head  out of 5  in  ⁵C₃ = 10 Ways

7 tosses-7th must be Head  

there are 3 Head   out of 6  in  ⁶C₃ = 20 Ways

Cases of Head wins = 1+ 4 + 10 + 20  = 35

similarly cases when  Tails Wins = 35

Total Possible cases = 35 + 35 = 70

70 is total number of possible ways in which the bet can play out.

Answer:

The area is 84. The missing side is 7.

Step-by-step explanation:

Okay so perimeter = length+length+width+width right? If 12 is the length, then 12+12=24, which is the length part of perimeter. 38-24=14 and 14/2=7. The missing side is 7 because 12+12+7+7=38 and the area is 84 because 12x7=84. Good luck!

[tex]LM = 10units[/tex]

Step-by-step explanation:

[tex]L( - 5,4),M(3, - 2)[/tex]

[tex]L( - 5,4),M(3, - 2) \\ L( { x }_{ 1 } , { y }_{ 1 } ),M( { x }_{ 2 } , { y }_{ 2 } )[/tex]

[tex]LM = \sqrt{ {( { x }_{ 2 } - { x }_{ 1 } )}^{2} + {( { y }_{ 2 } - { y }_{ 1 } ) }^{2} } [/tex]

[tex]LM = \sqrt{ {(3 - - 5)}^{2} + {( - 2 - 4)}^{2} } [/tex]

[tex]LM = \sqrt{ {(3 + 5)}^{2} + {( - 2 - 4)}^{2} } [/tex]

[tex]LM = \sqrt{ {(7)}^{2} + {( - 6)}^{2} } [/tex]

[tex]LM = \sqrt{64+ 36} [/tex]

[tex]LM = \sqrt{100} [/tex]

[tex]LM = 10units[/tex]

Answer:

Options (2) and (3)

Step-by-step explanation:

Slope of line segment is given by the formula,

Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

Here, the line given in the graph has the Rise as negative (Since, segment is slanting down) and Run as positive.

Therefore, slope of the segment is negative which describes that the function is decreasing in the interval 2.

Options (2) and (3) will be the correct options.

Answer:

Step-by-step explanation:

[tex]\frac{5x - 2}{4}+\frac{1}{2}=\frac{3y+2}{2}[/tex]

Multiply the equation by 4

[tex]4*\frac{5x - 2}{4}+4*\frac{1}{2}=4*\frac{3y+2}{2}\\[/tex]

5x - 2 + 2 = 2*(3y + 2)

5x +0 = 2*3y + 2*2

5x = 6y + 4

5x - 6y = 4 --------------------(I)

[tex]\frac{7y+3}{3}=\frac{x}{2}+\frac{7}{3}\\[/tex]

Multiply the equation by 6

[tex]6*\frac{7y+3}{3}=6*\frac{x}{2}+6*\frac{7}{3}\\[/tex]

2*(7y + 3) = 3x + 2*7

14y + 6 = 3x + 14

14y = 3x + 14 - 6

14y = 3x + 8

-3x + 14y = 8 ------------------------(II)

Multiply equation (I) by 3 and equation (II) by 5 and then add

(I)*3              15x - 18y = 12

(II)*5           -15x  + 70y = 40     {Now add}

                          52y = 52

                              y = 52/52

                            y = 1

Substitute y =1 in equation (I)

5x - 6*1 =  4

5x - 6 = 4

      5x = 4 +6

      5x = 10

         x = 10/5

x = 2

x > -1
