A 30-foot-long support wire for a 16-foot high streetlight runs from the top corner of a building to a point on the ground, forming a straight line. The length of the wire from the top of the building to the top of the street light is 6 feet. How tall is the building?
I think the answer is 20 ft
Answer:4
Step-by-step explanation:
2x2 is adding 2 and 2 together
The cost of bathing service per dog :
$324/27 = $12
x = <span>number of dogs she washes
</span>y = revenue
so the equation:
y = 12x
1 dog = $12
2 dogs = $12 x 2 = $24
3 dogs = $12 x 3 = $36
4 dogs = $12 x 4 = $48
use these coordinate points to graph it.
x - coordinate = <span>number of dogs she washes
</span>y - coordinate = total cost ($)
She will at least be 35 years old when the bankrupty is removed from her credit report.
Answer:
First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)
That is the first error of Alan.
Now, there is another error.
If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).
But we can not really divide by zero, so we should state that:
m can not be zero, if a line is horizontal, the perpendicular line must be vertical.
