Answer:

(-4,6)

Step-by-step explanation:

When you reflect a point across the x and then y-axis, it is called an Origin Reflection

Origin Reflections, to put it simply, is when you have two points (a,b) and you find their opposites (-a,-b)

You have the point (4,-6)

The origin reflection of this point is (-4,6)!

Solve using the quadratic formula. h2 + 8h + 8 = 0 Write your answers as integers, proper or improper fractions in simplest form

Marina86 [1]

A=1 b=8 c=8
h = [-8 +-sq root(64 - 4*1*8)] / 2
h = [-8 +-sq root(32)] / 2
h1 = -4 + 2.8284271247 
h1 = -1.1715728753 
h2 = -4 - 2.8284271247
h2 = - 6.8284271247

Norma-Jean [14]

Answer:

The amount of change in the balance of the account is an increase of $3160.57.

Step-by-step explanation:

i) first deposit is given as $1250

ii) second deposit is given as $3040.57

iii) first withdrawal is given as $400

iv) second withdrawal is given as $400

v) third withdrawal is given as $400

vi) first penalty removed is $35

vii) second penalty removed is $35

viii) therefore the change to the balance is given by

$1250 + $3040.57 - $400 - $400 - $400 + $35 + $35 = $3160.57

viii) Therefore the amount of change in the balance of the account is an increase of $3160.57.

Vikentia [17]

Mean or Average is all of the sums divided by how many of the choices are there, so all of 10,126+9,99+12,398+12,007+4567=49097 and divided by all the choices you have which is 5 is 9819.4

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y = ln(3x),

denis23 [38]

Using the disk method, the volume is obtained with the integral

$\displaystyle\pi\int_{y=1}^{y=5}\left(\frac{e^y}3\right)^2\,\mathrm dy=\frac\pi9\int_1^5e^{2y}\,\mathrm dy$

The radius of each disk is given by the horizontal distance from the axis of revolution, $x=0$ , to the logarithmic curve which we can write as a $x(y)$ :

$y=\ln(3x)\implies e^y=e^{\ln3x}=3x\implies x=\dfrac{e^y}3$

Then the volume of one such disk is $\pi x(y)^2$ .

The volume of the entire solid would be

$\displaystyle\frac\pi9\int_1^5e^{2y}\,\mathrm dy=\frac\pi{18}\int_1^52e^{2y}\,\mathrm dy=\frac\pi{18}\int_1^5e^{2y}\,\mathrm d(2y)$

$=\dfrac\pi{18}\left(e^{10}-e^2\right)$
