Write 5×5×5×5×4×4×4 in exponential form

Mathematics

Since 5 is being multiplied by itself 4 times, that part would be written as

5^4 (5 to the power of 4)

And since 4 is being multiplied by itself 3 times, that part would be written as 4^3 (4 to the power of 3)

Then, since they are being multiplied together the final answer in exponential form is 5^4 * 4^3.

Find the solutions of the following equations by extracting square roots 9x2-16=0 (z-2)2-36=0

natta225 [31]

The solutions of the equation $9x$ ² - 16 = 0is 4/3 and -4/3 and that of the equation $(z - 2)^{2} - 36 = 0$ is 8 and -4.

Solving the both quadratic equations by extracting square roots:

$9x^{2} - 16 = 0$

⇒ $9x^{2} = 16$

∴ On taking square-root of both sides, we get

$\sqrt{9x^{2} }$ = $\sqrt{16}$

⇒ $3x =$ $+4$ and $3x = -4$

⇒ $x$ = 4/3 and $x$ = -4/3

For the equation, $(z - 2)^{2} - 36 = 0$ , the solution is:

$(z - 2)^{2} - 36 = 0$

⇒ $(z - 2)^{2} = 36$

∴ On taking square-root of both sides, we get

$\sqrt{(z - 2)^{2} } = \sqrt{36}$

⇒ (z - 2) = 6 and (z - 2) = -6

⇒ z = 6 +2 and z = -6 + 2

⇒ z = 8 and z = -4

The solution of the equation $9x^{2} - 16 = 0$ is 4/3 and -4/3.

The solution of the equation $(z - 2)^{2} - 36 = 0$ is 8 and -4.

Point p is located in the first quadrant of a coordinate plane.If p is reflected across to form p',choose the four statements th

Kipish [7]

Answer:

When we do a reflection of a point (x, y) about a given line, the distance between the point (x, y) and the line is invariant under the transformation.

In the case of reflection over x-axis we have:

T (x, y) => (x, -y)

In the case of reflection over the y-axis, we have:

T (x, y) => (-x, y)

Because these two lines are perpendicular, a reflection over the x-axis leaves the distance between the point and the y-axis invariant (and the same for the inverse case)

Then 4 statements that will always be true:

1) The distance between p' and the x-axis is the same as the distance between p and the x-axis.

2) The distance between p' and the y-axis is the same as the distance between p and the y-axis.

From 1 and 2, we get:

3) The distance between p' and the origin is the same as the distance between p and the origin.

4) As we have a reflection, p' can not be in the same quadrant than p, then p' can not lie on the first quadrant.

a map shows that the top of a hill is 200m above sea level and the bottom of a lagoon is 15m below sea level. express these dist

Rus_ich [418]

Answer:

200 m

-15 m

215 m

Step-by-step explanation:

Given :

Top of hill = 200 m above sea level ; height of hill top is positive 200m = 200 m

Bottom of lagoon = 15m *below sea level ; bottom of lagoon = - 15m

We have related the height of the two points with respect to sea level ; points above sea level are represented as positive ; points below are represented as negative.

Difference between the two heights :

Hill top - bottom of lagoon :

200 m - (-15) m

200 m + 15 m

215 m

Difference between the heights is 215 m
