Answer:

4 * sqrt(3) / 3

Step-by-step explanation:

sin 60 = opposite / hypot = 2 / x

sin 60 is sqrt(3) / 2

2 / x = sqrt(3) / 2 -> 4 = x * sqrt(3)

x = 4 / sqrt(3) = 4 * sqrt(3) / 3

Answer:

24 Square Feet.

Step-by-step explanation:

Rewrite the fractions to have a common denominator to find the difference:

2/3 = 4/6

Difference = 4/6-5/6 = -1/6

Sequence formula = an = a1 + d(n-1)

A1 is the first term 5/6

And d = -1/6

Sequence = 5/6 -1/6(n-1)

Simplify to get an =(-n +6)/6

Answer:

D

Step-by-step explanation:

An open line is < and >

A filled line is > and equal, and < and equal

when you plug -3.5 into -6 you get 21 but when you go right, ex -3x-6 you get 18 which is less than 21

Answer:

Step-by-step explanation:

The interior angle of the m-gon is ...

  m-interior = 180 -360/m

The exterior angle of the k-gon is ...

  k-exterior = 360/k

The required relationships are ...

  m = 3k

  m-interior = 14/3(k-exterior)

Substituting for m, we can write the latter relation as ...

  (180 -360/(3k)) = 14/3(360/k)

Multiplying by 3k/180, we have ...

  3k -2 = 28

  k = (28 +2)/3 = 10

The values of k and m are 10 and 30, respectively.

_____

Check

The interior angle of the m-gon is 180 -360/30 = 168 degrees.

The exterior angle of the k-gon is 360/10 = 36 degrees.

The angle ratio is 168/36 = 14/3 as required.

Answer:

y = -2x + 7

Step-by-step explanation:

to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis

a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)

so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)

now, an equation for a line is written as Y = MX + B

M = slope

B = y intercept

our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation

y = -2x + 7

Answer:

y= -2x + 7

Answer:

  p (-1)  = -156

Step-by-step explanation:

Explanation:-

Given polynomial

           p(x)=7x³ -6x²+39x-104

Put x=-1

          p (-1)    = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104

                     = - 7 - 6 - 39 - 104

          p (-1)  = -156

Answer:

$71.40

Step-by-step explanation:

Before Tax Price: $68.00

Sale Tax: 5.00% or $3.40

After Tax Price: $71.40

Answer:

71.40

Step-by-step explanation:

Sales tax = 5% of 68

              [tex]=\frac{5}{100}*68\\\\=\frac{340}{100}\\\\= 3.40[/tex]

Sales tax = $ 3.40

Total cost = 68 + 3.40 = $ 71.40

Answer:

1) x-intercepts are at -3 and -4

2) x-intercepts are at 5/3 and 2

Step-by-step explanation:

1) y = -x^2 - 7x - 12  is -(x + 3) (x + 4)

2) y = 3x^2 + 11x + 10  is (3x + 5) (x + 2)

Answer: See explanation

Step-by-step explanation:

The best player on a basketball team makes 95​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 95% × 40

= 95/100 × 40

= 0.95 × 40

= 38

The​ second-best player makes 90​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 90% × 40

= 90/100 × 40

= 0.90 × 40

= 36

The​ third-best player makes 80​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 80% × 40

= 80/100 × 40

= 0.80 × 40

= 32

Answer:

y = 8x

Step-by-step explanation:

Given that :

Ornanment are packed in boxes

Number of ornament per box = 8

x = number of boxes packed

y = Number of ornaments

Number of Ornanments packed = (Number ornaments per box * number of boxes packed

y = 8 * x

y = 8x

Answer:

25x2 = 16

x2 = 16/25

x = ±4/5

Step-by-step explanation:

real = 2         imaginary =  6i

there's only two terms in the expression.

i is an imaginary number - it's not on the number line and it never will be; which means any TERM with i in it, is imaginary. 6i is one term so the entire term is imaginary since 6i will never be on the number line.

2 is on the number line which means it's a real number.

Answer:

x=10

Step-by-step explanation:

Pull out like factors :

  -9x + 90  =   -9 • (x - 10)

Equations which are never true:

2.1      Solve :    -9   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x-10 = 0

Add  10  to both sides of the equation :

                     x = 10
