Answer:

Slope (m) = \frac{y}{x} = \frac{2}{3} = 0.66666666666667

Step-by-step explanation:

0 = arctan (\frac{y}{x}) = 33.69006752598°

X = 4 – 1 = 3

Y = 4 – 2 = 2

Distance (d) = \sqrt{x^2+y^2}= \sqrt{13} =3.605551275464

Equation of the line:

y = 0.66666666666667x + 1.3333333333333

or

y=\frac{2}{3}x+\frac{4}{3}

When x=0, y = 1.3333333333333

When y=0, x = -2

A cell phone tower in a field casts a shadow of 100 ft. At the same time, a 4 ft 6 in post near the tower casts a shadow of 3 ft
Volgvan
This is the concept of linear proportionality;
We are required to find the height of the tower in feet. The height of the tower will be found as follows;
[height of tower]/[length of the shadow of tower]=[height of post]/[length of shadow of the post]
height of the tower =h
height of the shadow=100ft
height of post=4 ft 6in=4 1/2 ft= 9/2 ft
length of the post's shadow=3 ft 4 in 3 1/3 ft=10/3 ft

N/B 1 ft= 12 inches

thus;
h/100=(9/2)/(10/3)
multiplying both sides by 100 we get:
h=(9/2)/(10/3)*100
h=9/2*3/10*100
h=135 ft

the answer is 135 ft

Adjust the number into correct standard form.<br> 4381<br> ×<br> 10<br> 3
ZanzabumX [31]

Answer:

the standard form of the given number is 4.381 x 10⁶

Step-by-step explanation:

Given number = 4381 x 10³

The above number can also be written as; 4381.0 x 10³

In standard form, the decimal point will be moved three steps backward to the first digit (4) and the resulting is multiplied by 1000, as shown in the number below;

4381.0 x 10³ = 4.381 x 10³ x 1000

                     = 4.381 x 10⁶

Thus, the standard form of the given number is 4.381 x 10⁶
