Answer:
Mark's shadow would be 3 feet.
Step-by-step explanation:
If a building is 50 feet tall and casts a 25 foot shadow, then the shadow of an object is <u>1/2</u> the length of the actual object.
This can be supported by the division problem:
50 ÷ 2 = 25
If Mark is 6 feet tall, then we need to <em><u>divide</u></em> 6 by 2 in order to find the length of the shadow.
6 ÷ 2 = 3
Therefore, Mark's shadow would be 3 feet.
Hope this helps! :D
I'm not sure if you have done vectors as of yet, but you would first add the x components and y components separately.
x-components: 4 blocks + 5 block = 9 blocks
y-component: 2 blocks + 1 block = 3 blocks
Magnitude of this: √(x₂-x₁)²+(y₂-y₁)²
= √(9)²+(3)²
=√81+9
=9.5 blocks approx
Angle of of the resultant vector;
tanθ=y/x
tanθ=3/9
θ=tan⁻¹(3/9)
θ=18.43 degrees
Hope I helped :)
Answer: 
The area of a triangle is given by:
Where:
is the base of this right triangle
is the height of the triangle
Substituting the known values:
Finally, the area of this triangle is:
E=13,000 and<span>E=1/50R(1650-R)</span>
<span>
</span>
<span />0.02R(1650-R)=13000
<span>(0.02R)(1650)-0.02R²=13000</span>
<span /><span>0.02R²-33R+13000=0</span>
<span>R2-1650R+650000=0</span>

theres no link or answer choices but i can give u the definition
A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x.
