I think $10 cause basically 2 people find money and they spilt it in half so they each get $5 so it would mostly likely be $10 if I’m wrong just let me know :)

I think it is $10 also. Because they both got $5 and 5+5=10.

Use the mid-point rule with n = 4 to approximate the area of the region bounded by y = x3 and y = x. (10 points)
USPshnik [31]
See the graph attached.

The midpoint rule states that you can calculate the area under a curve by using the formula:
M_{n} = \frac{b - a}{2} [ f(\frac{x_{0} + x_{1} }{2}) +  f(\frac{x_{1} + x_{2} }{2}) + ... +  f(\frac{x_{n-1} + x_{n} }{2})]

In your case:
a = 0
b = 1
n = 4
x₀ = 0
x₁ = 1/4
x₂ = 1/2
x₃ = 3/4
x₄ = 1

Therefore, you'll have:
M_{4} = \frac{1 - 0}{4} [ f(\frac{0 +  \frac{1}{4} }{2}) +  f(\frac{ \frac{1}{4} + \frac{1}{2} }{2}) +  f(\frac{\frac{1}{2} + \frac{3}{4} }{2}) + f(\frac{\frac{3}{4} + 1} {2})]
M_{4} = \frac{1}{4} [ f(\frac{1}{8}) +  f(\frac{3}{8}) +  f(\frac{5}{8}) + f(\frac{7}{8})]

Now, to evaluate your f(x), you need to look at the graph and notice that:
f(x) = x - x³

Therefore:
M_{4} = \frac{1}{4} [(\frac{1}{8} - (\frac{1}{8})^{3}) + (\frac{3}{8} - (\frac{3}{8})^{3}) + (\frac{5}{8} - (\frac{5}{8})^{3}) + (\frac{7}{8} - (\frac{7}{8})^{3})]

M_{4} = \frac{1}{4} [(\frac{1}{8} - \frac{1}{512}) + (\frac{3}{8} - \frac{27}{512}) + (\frac{5}{8} - \frac{125}{512}) + (\frac{7}{8} - \frac{343}{512})]

M₄ = 1/4 · (2 - 478/512)
     = 0.2666

Hence, the <span>area of the region bounded by y = x³ and y = x</span> is approximately 0.267 square units.

A sport’s fan spent a total of $450 on baseball tickets. if only $4 and $5 tickets were bought, and there was an equal number at
Sindrei [870]
Equal number at each price?
does that mean there were an equal number of 4 dollar as 5 dollar tickets?

alrighty

so 4+5=9

450/9=50

50 four dollar tickets
50 five dollar tickets

Can anybody help me solve this? You must solve for x first.
gavmur [86]

Answer:

ABC = 65

Step-by-step explanation:

The sum of the angles of a quadrilateral are 360

2x-15 + x + 2x-15 +x = 360

Combine like terms

6x -30 = 360

Add 30 to each side

6x -30 +30 = 360+30

6x= 390

Divide by 6

6x/6 = 390/6

x=65

We want angle ABC

ABC = x

ABC = 65
