Answer:
Step-by-step explanation:
The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is L = StartRoot d squared + h squared EndRoot. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?
L = √d² + h²
Answer:
The height of the building that casts a shadow of 78m meters is 39m
Step-by-step explanation:
Let height be represented by H and the shadow is S
as they are directly proportional
H s
H=KS ( where K is a proportionality constant)
H=2.5m , S= 5m
On substituting in the equation
2.5 = K*5
K= 0.5
Now the equation becomes
H = 0.5*S
Height when shadow is 78m
H= 0.5*78
H= 39m
Answer:
One solution
Step-by-step explanation:
since the graph formed by them has interesting lines, it will just have one solution
Answer:
B)
Step-by-step explanation:
Because the y intercept remains the same and does not change at a constant rate like all the others.
A),C),and D) are wrong because they have a pattern and show liner relationship
Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is:
Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:
Add:
Divide by 2:
So, our midpoint is (7,4).
And we're done!
