Please help this is hard math
Rainbow [258]

Answer:

y=-4x+2

Step-by-step explanation:

  • First we find the slope of the line AB passing through the point (2,0)
  • line AB is perpendicular to the line y=\frac{1}{4}x-3 , this equation is slope intercept for, which is y=mx+b so our m or slope is \frac{1}{4}
  • Since the slope of line AB is perpendicular to m=\frac{1}{4} then we use the equation slope of line1\times slopeofline2=-1 , so what do we multiply \frac{1}{4} by to get -1? -4 right, so that's the slope of line AB with the point (2,0)
  • Now line CD is parallel to line AB, that means it has the same slope as AB, so slope of CD is -4
  • So we make the equation y-y_1=m(x-x_1) so m= -4 and our point is (-1,6)
  • y-(6)=-4(x-(-1)\\y-6=-4x-4\\y=-4x-4+6\\y=-4x+2 thats the equation of line side CD

A tree casts a shadow that is 8 feet long, a 3 foot mailbox cast a shadow that is 5 feet long. how tall is the tree?
madam [21]
Set up two fractions:
8/x and 3/5
Set them equal to each other and cross multiply to get:
8*5 = 3x
40 = 3x
13.3 = x or 13 and 1/3 feet tall.

What is the power dissipated by a 5ohm resistor if the current is 4A?​
posledela

Answer:

Answer: First, we use Ohm's law ( V = I × R ), to find the current through the resistor. The voltage across the resistor is V = 9 V. The resistance of the resistor is R = 100 Ω. Then, we can use the power rule ( P = I × V ), to find the power dissipated by the resistor

Step-by-step explanation:

i dont know if its the right answer but here

Answer:

88 inches

Step-by-step explanation:

Diameter is 2 times the radius (r) so divided 28 by 2 to get 14 as the radius.

Plug this in:

2π14
