Factor out the GCF of 9x first. 9x(x^2-1)=0; 9x(x+1)(x-1)=0; set each factor equal to zero. x=0, x=-1,. x=1 each has a multiplicity of one.
Answer:
A. 0.0625
B. 0.1089
C. 0.81
D. 0.0196
Step-by-step explanation:
The proportion of variance is shared by the two correlated variables is given as the r².
Therefore,
For A. r = 0.25
Proportion of variance is shared by the two correlated variables = 0.25²
= 0.0625
For B. r = 0.33
Proportion of variance is shared by the two correlated variables = 0.33²
= 0.1089
For C. r = 0.90
Proportion of variance is shared by the two correlated variables = 0.90²
= 0.81
For D. r = 0.14
Proportion of variance is shared by the two correlated variables = 0.14²
= 0.0196
Answer:
about 100 cm²
Step-by-step explanation:
The side length of the rhombus is 1/4 of the perimeter so is 10 cm. The length of half of the other diagonal will be the length of the leg of a right triangle with hypotenuse 10 and leg 7 (half the given diagonal).
d= √(10² -7²) = √51
Then the area of the rhombus is the product of this and the given diagonal:
A = (14 cm)(√51 cm) ≈ 99.98 cm²
The area of the rhombus is about 100 cm².
Answer:
Either one! If it is a long-term goal, it is to most likely have an effect on you for most of your life example: buying a house, going to college, etc.
A short term goal is something you could reach in just a few months and it will probably not have the same effect as the long term ones are, however some do. Example: changing your diet, eat healthier, etc.
