Answer:

D. d ≈ 9.4

Step-by-step explanation:

[] We can use the distance formula to solve

-> The distance formal is attached.

$d = \sqrt{(4-9)^{2}+ (2-10)^{2} }$

$d = \sqrt{(-5)^{2}+ (-8)^{2} }$

$d = \sqrt{25+ 64 }$

$d = \sqrt{89}$

d ≈ 9.4

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Divide 320 into 8 equal groups

alexandr402 [8]

Answer:

320 divided by 8 is 40. 40 times 8 is 320, so it works backwards.

8x over 8 to the power of 5 = 8 to the power of 7

neonofarm [45]

Ok so if the equation is this
8x/8( 5 exponent) = 8 (7 exponent) the answer should be 8( 11 exponent)
My work is attached below.
Sorry for my awful handwriting!

Whats one plus 1 and 2 plus 2 and 3 plus 3 times 0 plus 24 times 8

ahrayia [7]

The answer is 197.

1 and 2 = 3
3+2=5
3+3=6
6x0=0
24x8=192
5+0=5
192+5=197

a street light is at the top of a 18 ft tall pole. a woman 6 ft tall walks away from the pole with a speed of 4 ft/sec along a s

shutvik [7]

The most appropriate choice for similarity of triangles will be given by -

Speed of tip of the shadow of woman = 6 ft/s

What are similar triangles?

Two triangles are said to be similar, if the corrosponding angles of the triangles are same and the corrosponding sides of the triangles are in the same ratio.

Here,

The diagram has been attached here

Let the distance of woman from the pole be x ft and the distance of tip of the shadow to the pole be y ft.

Height of street light = 18 ft

Height of woman = 6ft

The two triangles are similar [As height of woman is parallel to the height of pole]

$\frac{y - x}{6}=\frac{y}{18}\\18y - 18x = 6y\\18y - 6y = 18x\\12y = 18x\\y = \frac{18}{12}x\\y = \frac{3}{2}x\\$

To find the speed, we have to differentiate both sides with respect to time 't'

$\frac{dy}{dt} =\frac{3}{2}\frac{dx}{dt}\\\frac{dy}{dt}=\frac{3}{2} \times 4\\\frac{dy}{dt} = 6$

Speed of tip of her shadow = 6 ft
