Answer:

(2,1)

Step-by-step explanation:

y = -4x + 9  -------------->eq1

y = 3x - 5  --------------->eq2

consider eq 1 and put in eq2

-4x+9=3x-5

add -9 on both sides

-4x=3x-14

add -3x on both sides

-4x-3x=-14

-7x=-14

x=2

put in eq1

y=-4(2)+9

y=1

Express the given integral as the limit of a riemann sum but do not evaluate: the integral from 0 to 3 of the quantity x cubed m
WARRIOR [948]
We will use the right Riemann sum. We can break this integral in two parts.
\int_{0}^{3} (x^3-6x) dx=\int_{0}^{3} x^3 dx-6\int_{0}^{3} x dx
We take the interval and we divide it n times:
\Delta x=\frac{b-a}{n}=\frac{3}{n}
The area of the i-th rectangle in the right Riemann sum is:
A_i=\Delta xf(a+i\Delta x)=\Delta x f(i\Delta x)
For the first part of our integral we have:
A_i=\Delta x(i\Delta x)^3=(\Delta x)^4 i^3
For the second part we have:
A_i=-6\Delta x(i\Delta x)=-6(\Delta x)^2i
We can now put it all together:
\sum_{i=1}^{i=n} [(\Delta x)^4 i^3-6(\Delta x)^2i]\\\sum_{i=1}^{i=n}[ (\frac{3}{n})^4 i^3-6(\frac{3}{n})^2i]\\
\sum_{i=1}^{i=n}(\frac{3}{n})^2i[(\frac{3}{n})^2 i^2-6]
We can also write n-th partial sum:
S_n=(\frac{3}{n})^4\cdot \frac{(n^2+n)^2}{4} -6(\frac{3}{n})^2\cdot \frac{n^2+n}{2}

If YX=3x-4 and MO=9x-20, then MO=? {Diagram not necessarily drawn to scale.} *
Sveta_85 [38]

Answer:

Step-by-step explanation:

I assume that XY is midsegment of a triangle, then MO = 2 XY

9x - 20 = 2( 3x - 4 )

9x - 20 = 6x - 8

3x = 12

x = 4

MO = 9(4) - 20 = 16 units

Answer:

$234,516.7371

Step-by-step explanation:

A = P (1 + [ r / n ]) ^ nt

A = 175000(1 + \frac{.05}{1})^1(2002-1996)

   = 175000(1.05)^6

   = 175000(1.340095640625)

   = 234,516.7371
