Answer:

54

Step-by-step explanation:

a + b + c = 18

abc + bca + cab = ???

18 / 3 = 6

a = ? = 6

b = ? = 6

c = ? = 6

(6 + 6 + 6) + (6 + 6 + 6) + (6 + 6 + 6)

(18) + (18) + (18)

abc + bca + cab = 54

graph the parabola y equals negative x squared + 3 to graph a parabola plot the vertex and four additional points two on each si
Nataliya [291]

You don't have the graph icon here, so we'll have to graph this parabola without it.


Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).


Plot (0,3). Besides being the vertex, this point is also the max. of the function.


Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.

Use the x-intercept method to find all real solutions of the equation -9^3-72^2-96x+36=3x^3+x^2-3x+8
Vadim26 [7]

Answer:

 x ≈ 0.290640965127

Step-by-step explanation:

y subtracting the right side of the equation, we get a function that is zero at a real solution for x. The only x-intercept is at approximately 0.290640965127.

___

The graph shows the x-intercept to be 0.2906. The value above was obtained by Newton's method iteration. The roots of this cubic will all be irrational.

Mickey and Donald earn $53 weekend after taxes Mickeys share is seven dollars greater than Donald's how much does Donald earn ea
igor_vitrenko [27]

Donald earns $23 each weekend and Mickey earns $30.

Step-by-step explanation:

Given,

Money earned by Mickey and Donald = $53

Let,

Share of Mickey = x

Share of Donald = y

According to given statement;

x+y=53    Eqn 1

x = y+7     Eqn 2

Putting value of x from Eqn 2 in Eqn 1

(y+7)+y=53\\y+7+y=53\\2y=53-7\\2y=46

Dividing both sides by 2

\frac{2y}{2}=\frac{46}{2}\\y=23

Putting y=23 in Eqn 2

x=23+7\\x=30

Donald earns $23 each weekend and Mickey earns $30.

Find the value of questions​
Zolol [24]

Answer:

The simplified expression is:

\frac{3^9y}{2\times \:81}=\frac{243y}{2}

Step-by-step explanation:

Given the expression

\frac{3^9\times \:y}{2\times 81}

solving the expression

\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}

        =\frac{3^9y}{3^4\times \:2}                ∵    162=3^4\times \:2      

        =\frac{3^5y}{2}                   ∵   \mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

       =\frac{243y}{2}                  ∵    3^5=243

Therefore, the simplified expression is:

\frac{3^9y}{2\times \:81}=\frac{243y}{2}
