Answer:
y=2 16/25
in other words, two and sixteen twenty-fifths
Step-by-step explanation:
y/2-1/5=2-y/3
Move the variables to one side and constants to the other
y/2+y/3=2+1/5
Multiply y/2 by 3/3 and y/3 by 2/2 so that they have a common denominator
3y/6+2y/6=2 1/5
5y/6=11/5
Cross multiply
66=25y
y=66/25
y=2 16/25
HOPE THIS HELPS!!!
Linear
This is because an exponential function increases at an exponential rate. Or, with multiplication.
Linear functions increase at a constant rate, with addition.
It’s 60 degrees so the first one
For given problem:
Put midpoint of ellipse, (0,0) at epicenter of bridge at
ground level.
Specified length of vertical major axis = 70=2a
a=35
a^2=1225
Equation of ellipse:
x^2/b^2+y^2=1
plug in coordinates of given point on ellipse(25, 10)
25^2/b^2 + 10^2/a^2 = 1
625/b^2 + 100/1225=1
625/b^2 = 1 - 100/ 1225 = .918
b^2 = 625/.918 ≈ 681
b ≈ 26.09
length of minor axis = 2b = 2(26.09) ≈ 52.16 ft
Span of bridge ≈ 52.16 ft
Answer:
C
Step-by-step explanation:
The general rule is that any two leg lengths must exceed the third.
A) won't. 1 + 1 = 2. The 2 ones lay flat across the 2.
B) 2 + 1 = 3. Won't work for the same reason as A
C) works fine. Any 2 will exceed the third.
D) can't happen. 7 + 7 < 15.
