Due soon!! <br>Find the measure of GE¯¯¯¯¯¯¯¯. A. 14 B. 20 C. 15 D. 16

Nataly_w [17]

Answer:

D. 16

Step-by-step explanation:

$GH^2 = GF \times GE$

$12^2 = 9 \times (9+x - 2)$

$144= 9 \times (7+x)$

$\frac{144}{9}= (7+x)$

$16= 7+x$

$16-7=x$

$9=x$

GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2

GE = 16

Ill give all my points to someone who can solve this probability problem correctly and clearly to understand.

Mashutka [201]

Answer:

+5.20 µC

Explanation:

Given that

Charge =−5.20 µC and radius= 5.40 cm.

Insert a +10.4- µC charge at the center of the sphere

As we know that according to Gauss's theorem electric field inside the metal is zero.

When +10.4 µC charge insert but the total charge on the sphere should be −5.20 µC.So the charge on the outer surface of the sphere will be +5.20 µC.

What is the cube root of 27x18? 3x6 3x9 9x6 9x9

vredina [299]

Solution:

A is the correct option.

Explanation:

We have to find the cube root of $27x^{18}$

In order to find the cube root of the expression, we find the factors of 27.

$27= 3 \times 3\times 3= 3^3$

Also x^18 can be written as

$x^{18}=(x^6)^3$

Replace the given expression with these values, we get

$\sqrt[3]{27x^{18}} =\sqrt[3]{3^3 \cdot (x^6)^3 }$

Now, we have the formula,

$\sqrt[n]{x^n} =x$

Using this formula, the cube with the cube root got cancelled and we are left with

$\sqrt[3]{27x^{18}} = 3\cdot x^6$

Therefore, the cube root of 27x^18 is 3x^6.

A is the correct option.
