Answer:
A. -10
Step-by-step explanation:
Hi there!
We are given that the equation of line m is , and we want to find the slope of the line perpendicular to m
Perpendicular lines have slopes that multiply to get the result of -1
So let's find the slope of line m
The equation is written in the form y=mx+b, where m is the slope, and b is the y intercept
As is in the place of where the slope should be, is the slope
Now find the slope of the perpendicular line with this formula:
In that case,
Multiply both sides by 10
So the slope of the perpendicular line is -10, or A
Hope this helps!
Answer:
58 ft.
Step-by-step explanation:
We will use trigonometry to find the distance.
We know that he is 29 ft above the ground (26, height of building, + 3, height of bird).
We use the angle 60 and we see that we have a known side which is adjacent to the angle. The side we are trying to find is the hypotenuse. We will be using cos because cos uses adjacent and hypotenuse sides of triangle.
cos60 = 29/x
cos60x = 29
29/cos60 = x
x = 58
He must fly 58 feet in order to get to the ground.
You can find it using a sinentific calculator if you have one just look for the functions
Answer:
Step-by-step explanation:
Givens
- Linda 35 mph
- Martin 60 mph
- distance travelled = 855 miles
Formula
Linda's speed * t + martin's speed * t = 855
s1 * t + s2 *t = 855
Solution
35*t + 60*t = 855t Combine the left
95t = 855 Divide both sides by 95
95t/95 = 855/95
t = 9
Answer
They will meet in 9 hours.
But x must be a natural number, so the answer is
