If a vertical pole 30 ft tall casts a shadow 8ft long, how long would the shadow of 40-ft pole be at the same time and place

1 answer:

5 0

Since it as at the same time and place.

Let x be the length of the shadow of the 40-ft pole.

The ratio from 30 and 8 would have to be the same as 40 and x.

30:8 = 40:x

30/8 = 40/x Cross multiply

30x = 40*8

x = 40*8 / 30 = 32/3 = 10.67

Length of shadow for 40ft is 10.67 ft.

Answer: y= -3x + 5

Step-by-step explanation:

y2-y1 divide by x2-x1 = m

therefore you would do 8 - -4= 12 divide by -1 - 3= -4 which gives you 12 divided by -4

m= 12/-4 aka m = -3

and to find the y intercept you should use one of the point coordination to plug it into the formula y=mx+ b

use (-1,8)

8= -3(-1) + b

8= 3+b

subtract 3 from both sides

b= 5

then plug the m and the b into y=mx + b

and you get y= -3 + 5

Which formula decribe the following geometric equence? Remember that n repreent the term number. 2, 6, 18, 54,. An = 3 · 2 n - 1

Goryan [66]

For the given geometric progression, the nth term of the given GP is $A_n=2.3^{n-1}$ .

Option (C) is correct.

What is the Geometric Progression?

Geometric Progression (GP) is a type of sequence in mathematics in which each succeeding term is produced by multiplying each preceding term by a fixed number known as a common ratio. This progression is also known as a pattern-following geometric sequence of numbers.

The given sequence is 2, 6, 18, 54

here the first term(a) = 2 and the common ratio(r) = 6/2 =3

Then by using the formula for the nth term of a GP, we get

$A_n=ar^{n-1}\\\\A_n=2.3^{n-1}$

Hence the nth term of the given GP is $A_n=2.3^{n-1}$ .
