Answer:
C. 1/(x^2 +1) > 0
Step-by-step explanation:
The cube of a negative number is negative, eliminating choices B and D for certain negative values of x.
1/x^2 is undefined for x=0, so cannot be compared to zero.
The value 1/(x^2+1) is positive everywhere, so that is the expression you're looking for.
1/(x^2 +1) > 0
Answer:
y=3(x+4)²+2
Step-by-step explanation:
Answer:
a. Not proportional
b. Proportional;
k = ⅞
Step-by-step explanation:
A proportional relationship is usually represented in the format, y = kx. k here represents constant of proportionality. This shows that x and y are directly proportional.
a. y = -2x + 9 is not a proportional equation.
b. y = ⅞x is a proportional equation.
Constant of proportionality: k = ⅞
Answer:
Probability that it lands in the shaded region = 54/72 = 0.75 = 75%
Step-by-step explanation:
Area of a triangle = 1/2 x base x height
Area of a parallelogram = base x height
Area of triangle JKL = 1/2 x 12 x 12 = 72 cm²
Area of parallelogram = 6 x 3 = 18 cm²
Therefore, area of shaded part = 72 - 18 = 54 cm²
Probability that it lands in the shaded region = 54/72 = 0.75 = 75%
