So simplified is distributing it, so
either 1/a* 1/a* 1/a
or (1^3/a^3)

which gives you 1/(a^3)

What’s the answer ????

Temka [501]

Answer:

Answer is 4/25

Step-by-step explanation:

0.16*100 = 16 which would allow us to say 16/100

now you can divide 16 and 100 by 4 which would be

16/4 = 4 and 100/4= 25

therefore the answer is 4/25

HELP!!<br>Find the third term of (x^2+3y)^3

lana66690 [7]

Answer:

$T_{3}=27{x}^{2}y^2$

Step-by-step explanation:

The given binomial expression is:

$( {x}^{2} + 3y)^{3}$

When we compare to:

${(a +b)}^{n}$

We have

$a = {x}^{2}$

$b = 3y \\ n = 3$

The nth term is given by;

$T_{r+1}=^nC_ra^{n-r}b^r$

To find the 3rd term, we put:

$r + 1 = 3 \\ r = 2$

We substitute into the formula to get:

$T_{3}=^3C_2( {x}^{2} )^{3-2}(3y)^2$

We simply:

$T_{3}=3( {x}^{2} )^{1} \times 9y^2$

$T_{3}=27{x}^{2}y^2$

Answer: x = 148 degrees

Step-by-step explanation:

This problem makes use of Supplementary Angles. Supplementary Angles states that two angles that make up a line add to 180. Thus, simply use the equation 32 + x = 180

x = 148

From a distance of 110 m, the angle of elevation to the top spire of a tower is 35°.

Nady [450]

Answer:

77 m

Step-by-step explanation:

The geometry can be modeled by a right triangle. The distance from the viewpoint to the base of the tower is 110 m, the leg of the triangle adjacent to the angle. The height of the spire is the leg of the triangle opposite the given angle. The relevant trig relation is ...

Tan = Opposite/Adjacent

Using the given numbers, we find ...

tan(35°) = height/(110 m)

height = (110 m)tan(35°) = (110 m)×0.700208 ≈ 77.0 m

The height of the tower is about 77 meters.
