Answer:
58
Step-by-step explanation:
range = largest number - smallest number
I'm reading this as ..... 36o more then the measure of its complementary angle.
x = 90 - x + 36 add 90 and 36 together.
x = 126 - x Add x to both sides.
2x = 126
x = 126 /2
x = 63
The complementary angle is 90 - 63 = 27
The question is is 63 36 bigger than 27
27 + 36 = 63 and the angles are
Answer 27o and 63o
Answer: The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
Step-by-step explanation:
Ok so R=alfonso's rate
w=wind rate=4
d=rt
with wind rate is R+4
agaoins wind rate is R-4
with wind distance is 34
against is 18 miles
time is same
34=(r+4)t
18=(r-4)t
34=(r+4)t
divide both sides by (r+4)
34/(r+4)=t
18=(r-4)t
divide both sides by (r-4)
18/(r-4)=t
18/(r-4)=t
34/(r+4)=t
set equal to each other
18/(r-4)=34/(r+4)
multiply both sides by (r-4)(r+4)
18(r+4)=34(r-4)
distribute
18r+72=34r-136
subtract 18r from both sides
72=16r-136
add 136 to both sides
208=16r
divide both sides by 16
13mph
answer is 13mph with no wind
