Answer:

<em>Option D.</em>

Step-by-step explanation:

To raise a product to an exponent, you must raise each factor of the product to the exponent. The product being raised to an exponent is 4z^8. This product is being raised to the -3 power. To raise it to the -3 power, you must raise each factor of the product to the -3 power.

(4z^8)^-3 = 4^-3 * (z^8)^-3.

4 must be raised to the -3 power, and z^8 must also be raised to the -3 power.

How many solutions can be found for the equation 4z + 2(z - 4) = 3z + 11
Gnom [1K]
4z+2(z-4)=3z+11  perform indicated multiplication on left side

4z+2z-8=3z+11  combine like terms on left side

6z/-8=3z+11  add 8 to both sides

6z=3z+19  subtract 3z from both sides

3z=19  divide both sides by 3

z=19/3 

z=6 1/3

So there is only one solution when z=6 1/3

a woman 1.65. tall stood 50m away from the foot of a tower,and observe that the angle of elevation of the top of the tower to be
ElenaW [278]

\sf\huge\underline{\star Solution:-}

\rightarrowLet the women's height be AE and distance between the women and tower be AC.

Also let the height of tower be BC.

\rightarrowNow, clearly it is forming a triangle.

So, in triangle ABC,

\rightarrow\sf{Tan50° \:= \: \frac{BC}{AC}}

\rightarrow\sf{1.19 \:= \: \frac{BC}{50}}

\rightarrow\sf{1.19 ×50\:= \: BC}

\rightarrow\sf{59.5m\:= \: BC}

\rightarrowHence, BC = 59.5m

So, BD(total height of the tower)\sf{ = \:BC+CD}

\sf{= \:59.5+1.65}

\sf{=\: 61.15m}

Therefore, total height of the tower =\sf\purple{ 61.15m.}
