Place the indicated product in the proper location on the grid. (4ya - 6xb)(4ya + 6xb)

k0ka [10]

Product of $(4ya - 6xb)(4ya + 6xb)$ is $16y^2a^2-36x^2b^2$

Step-by-step explanation:

We need to find the product of $(4ya - 6xb)(4ya + 6xb)$

Finding product:

Multiplying both terms:

$(4ya - 6xb)(4ya + 6xb)\\=4ya(4ya+6xb)-6xb(4ya+6xb)\\=16y^2a^2+24yaxb-24xbya-36x^2b^2\\=16y^2a^2-36x^2b^2$

So, product of $(4ya - 6xb)(4ya + 6xb)$ is $16y^2a^2-36x^2b^2$

Starting at 100% I have 82 clients 2 of them didn't get a check up what percent does that leave us at ?

murzikaleks [220]

82 total clients

2 did NOT get a checkup

(82 - 2) = 80 clients DID get a checkup

80/82 = 0.97561 = 97.561% of your clients have had their checkup.

Interestingly, that's the exact same percentage of your clients who have had lunch. Perhaps ... I'm not stating this as a fact, but it's a hunch ... just maybe the other two have not had their checkups yet because they are out getting lunch.

An 8-sided die is formed when two square pyramids are attached by their bases. The perimeter of the base shape is 6 centimeters.

bogdanovich [222]

1. Check the picture attached. Consider the half of the 8-sided die, that is the pyramid ABCDE:

2. The perimeter of the base is 6, so each side of the base is 6/4=3/2

3. The distance between the tallest points is 2 cm, si the height of Pyramid ABCDE is 1 cm.

4. Consider the right triangle EOM in the figure:

EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is $\sqrt{1+ ( \frac{3}{4} )^{2} }= \sqrt{1+ \frac{9}{16} }= \sqrt{ \frac{25}{16} }= \frac{5}{4}$ (cm)

5. So side EBC has area
$\frac{1}{2}BC*EM= \frac{1}{2}* \frac{3}{2}* \frac{5}{4}= \frac{15}{16}$

6. The total area is 8*Area(EBC)= $8* \frac{15}{16}= \frac{15}{2}=7.5 ( cm^{2} )$
