Answer:
C. 30-60-90
Step-by-step explanation:
the ratio for a 3-6-9 triangle is x, 2x, x√3
if x=8, then 2x=16, and x√3 =8√3
it's not A because it is a right angle triangle.
it's not B because the ratio for an isoceles triangle is x:x:x√2. since a and b are not the same value, it can be assumed that it is not the answer
Given v=31 and s=0
<span>H(t) = -16t2 + vt + s
</span>
H(t) = -16t^2 + 31t
dH/dt = -32t + 31
<span>At the maximum height, dH/dt = 0
-32t + 31 =0
t = 31/32 = .96875
substitute back to H(t)
</span>
H( .96875) = 15.0 ft
ans is C
Answer:
Option D)Neither solution is extraneous.
Step-by-step explanation:
we have

we know that
two possible solutions are x=-7 and x=1
<u><em>Verify each solution</em></u>
Substitute each value of x in the expression above and interpret the results
1) For x=-7


----> is true
therefore
x=-7 is not a an extraneous solution
2) For x=1


----> is true
therefore
x=1 is not a an extraneous solution
therefore
Neither solution is extraneous
Answer:
12=3x+4y in slope-intercept form is y=-3/4x+3 and the slope that's negative is the first one so therefore it's the first one.
Step-by-step explanation:
Answer:
v=a×b×c
v=8.53 cm ×2.4 cm ×1.0 cm
d=m/v
d=52.7064g
20.472 cm3
d=2.57 g/ cm3
