Answer:
The percentage decrease in the depth is 45%
Step-by-step explanation:
January, lake depth = 1086 feet
august, lake depth = 597.3 feet
The decrease in depth = 1086 - 597.3
= 488.7 feet
Percentage decrease = decrease over January lake depth multiply by 100%
% decrease = (488.7/1086)*100%
=0.45*100%
= 45%
Answer:
B.) The graph of m(x) is wider.
Both graphs open upward.
Both have the axis of symmetry x = 0.
The vertex of m(x) is (0, 4); the vertex of n(x) is (0, 0).
Step-by-step explanation:
When the coefficient before x² is greater than 1, the curve of the graph is narrower. When the coefficient is less than 1, the curve of the graph is wider.
When the coefficient in front of x² is positive, the graph opens upwards. When the coefficient is negative, the graph opens downwards.
The axis of symmetry is the "x" value which divides the curve into two equal sections. Their axis of symmetry are both x = 0 because their vertexes (the lowest point of the curve) are both at x = 0.
The vertex can be found by plugging x = 0 into both of the equations and then solving. The resulting value is the "y" position of the vertex.
m(0) = 0.7(0)² + 4 n(0) = (0)²
m(0) = 0 + 4 n(0) = 0
m(0) = 4
Therefore, the vertexes are m(x) = (0,4) and n(x) = (0,0).
Part A)
F(s) = 3s + 35 is the number of flowers
S(w) = 15w is the number of seeds planted
Since s = 15w, replace s in the first equation with 15w and simplify:
F(s) = 3(15w) + 35
F(s) = 45w + 35
B)
The composited equation calculates the number of flowers That bloomed.
C) replace w with 36 and solve.
45(w) + 35 = 45(36)+35 = 1620 + 35 = 1,655 flowers bloomed in 36 weeks.
