You are measuring the height of a lamppost. You stand 40 inches from the baseof the lamppost. You measure the angle of elevation from the ground to the top!
of the lamppost to be 70°. Find the height h of the lamppost to the nearest inch.

Answers

Answer:

110in

Step-by-step explanation:

The horizontal distance from where you stand to the lamp post is 40 inches.

Let the height of the lamp post be y inches.

The angle of elevation from the ground to the top!

of the lamppost to be 70°.

The height , y and the horizontal distance, form the legs of a right triangle .

We can use the tangent ratio, to calculate the height of the lamp post .

$\tan(70 \degree) = (y)/(40)$

$y = 40 \tan(70)$

$y = 109.9$

To the nearest inch, the height is 110 inches

Helpppp Plsssss!!! Thanks

Answer:

It's B

Step-by-step explanation:

-5x(x^2)=-5x^3

-5x(2x)= -10x^2

-5x(3)= -15x^2

All together: -5x^3 - 10x^2 - 15x

Answer:

B. $-5x(x^(2) +2x+3)$

Step-by-step explanation:

$-5x^(3) -10x^(2) -15x$

Apply exponent rule

$-5x^(2) x-10xx-15x$

Rewrite 15 as 5*3

Rewrite 10 as 5*2

= $5x^(2) x-5*2xx-5*3x$

Factor out common term -5x

= $-5x(x^(2) +2x+3)$

the perimeter of a rectangular window is 634 inches if the length of the window is 205 inches what is the width of the window

Answers

So you first divide 634 by 2 to get the length of one length and one width.
634/2=317
Then you subtract 205, the length, from the length and the width(317).
317-205=112 inches. Yay!

Which transformations will produce similar, but not congruent, figures?Choose all answers that are correct.
A.Parallelogram JKLM is rotated 90° clockwise and then reflected across the y-axis to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.
B.Parallelogram JKLM is dilated by a scale factor of 6 and then translated 2 units down to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.
C.Parallelogram JKLM is translated 6 units up and then dilated by a scale factor of 10 to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.
D.Parallelogram JKLM is translated 8 units left and then reflected across the x-axis to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ

Answers

so if similar means that the points are in the same orientation reletive to each other (exg point 1 is to the right of point 2 and both are above points 3 and 4)

so rotations and reflections change the orientation reletive to each other so choices A and D are out

Dialations and translations just move the whole thing, yet it stays the same points reletive to each other so the answers are B and C

Sorry if it is wrong, don't know this the best
I think the answer is B and C

Answer:

B.Parallelogram JKLM is dilated by a scale factor of 6 and then translated 2 units down to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ; and C.Parallelogram JKLM is translated 6 units up and then dilated by a scale factor of 10 to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.

Step-by-step explanation:

Some transformations are called rigid transformations. This is because they preserve congruence. These are translations, rotations and reflections. Any combination of these three transformations will result in congruent figures.

This means if we want similar and not congruent figures, the figure must be dilated. The only two choices that mention dilations are B and C.

Whats 3x9 + 10 x 36/6?

Answers

The solution to the expression 3 * 9 + 10 * 36/6 is 87

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

3 * 9 + 10 * 36/6

Evaluate all the products in the expression

so, we have the following representation

3 * 9 + 10 * 36/6 = 27 + 360/6

Evaluate all the quotients in the expression

so, we have the following representation

3 * 9 + 10 * 36/6 = 27 + 60

Lastly, we have

3 * 9 + 10 * 36/6 = 87

Hence, the solution is 87
