Answer:
See the attached for a graph.
Step-by-step explanation:
The edge of the solution space is marked by the line ...
... y = 4 - 2x
This is in slope-intercept form. It has a y-intercept of 4 and a slope of -2. Because the relation symbol is "less than" (with no "or equal to"), the line itself is not part of the solution space. It is graphed as a dashed line for that reason.
The values of y in the solution space are those <em>less than</em> the ones that make up the line, so the shading is of the half-plane <em>below</em> the line.
Answer:
y = 1.44x⁴
Step-by-step explanation:
From the question,
Y∝d²
To remove the proportionality sign we introduce a constant.
Y = kd²............... Equation 1
make k the subject of the equation
k = Y/d²............. Equation 2
Given: Y = 4, d = 10
Substitute these values into equation 2
k = 4/10²
k = 4/100
k = 0.04
Substitute these value of k in equation 1
Y = 0.04d²................ Equation 3
Similarly,
d∝x²,
d = Cx²
make C the subject of the equation
C = d/x²................... Equation 4
Given: d = 24, x = 2
Substitute into equation 4
C = 24/2²
C = 24/4
C = 6
Hence,
d = 6x²................... Equation 5
Substitute the value of d in equation 5 into equation 3
y = 0.04(6x²)²
y = 0.04(36x⁴)
y = 1.44x⁴
Hence the formula for y in terms of x is y = 1.44x⁴
