Graph the image of Kite BCDE after a translation 5 units down.

NeTakaya

Answer:

See attachment for the translated kite

Step-by-step explanation:

Given

The attached image of BCDE

Required

Translate 5 units down

From the attachment;

$B = (-7,0)$

$C = (0,5)$

$D =(-7,10)$

$E = (-10,5)$

The rule to translate 5 units down is:

$(x,y) \to (x,y-5)$

So:

$B' = (-7,-5)$

$C' = (0,0)$

$D' = (-7,5)$

$E' = (-10,0)$

The area of the region under the curve given by the function f(x) = 2x2 + 6 on the interval [0, b] is 36 square units, where b &

choli [55]

The area as a function of b is given by

$a(b)=\int\limits^b_0 {(2x^2+6)} \, dx =\frac{2}{3}b^3+6b$

You want to find b such that a(b) = 36.

... (2/3)b^3 +6b = 36

... b^3 +9b -54 = 0 . . . . multiply by 3/2 to clear fractions

A graphing calculator shows this equation to have one real solution at b=3.

The value of b is 3.
