Answer:
A.quadratic
Step-by-step explanation:
3x+x^2+4
Put in order from largest to smallest power of x
x^2 +3x+4
The highest power is 2
A.quadratic highest power 2
B. quartic highest power 4
C. linear highest power 1
D. cubic highest power 3
Answer:
j=46
Step-by-step explanation:
34=j-12
add 12 to 34 to isolate j
the answer to that is 46
j=46
Answer:
there is not enough information because x and 55 are parrallel, not congruent.
Step-by-step explanation:
Answer:
0.28cm/min
Step-by-step explanation:
Given the horizontal trough whose ends are isosceles trapezoid
Volume of the Trough =Base Area X Height
=Area of the Trapezoid X Height of the Trough (H)
The length of the base of the trough is constant but as water leaves the trough, the length of the top of the trough at any height h is 4+2x (See the Diagram)
The Volume of water in the trough at any time


=8h(8+2x)
V=64h+16hx
We are not given a value for x, however we can express x in terms of h from Figure 3 using Similar Triangles
x/h=1/4
4x=h
x=h/4
Substituting x=h/4 into the Volume, V


h=3m,
dV/dt=25cm/min=0.25 m/min

=0.002841m/min =0.28cm/min
The rate is the water being drawn from the trough is 0.28cm/min.
Answer:
The answer should be 103.
Step-by-step explanation:
If Herman has been put on the diet for 4 weeks and has lost the same amount of weight each week you could divide 412 by 4 and get 103, not sure about the simplified mixed number though. Sorry.
