Answers:
1: y = 1x + 0.5
3: the y-intercept shows that the original data began above 0 and has had a steady increase since. (not sure abt this one)
4: I'm sorry i don't know this one
5: the data collection shows that the height to arm span has a ratio of 1 throughout you can tell this by using the line of best fit.
6: according to the line of best fit the height of the person will also be about 66 inches.
7: according to the line of best fit the arm span will also be about 74 inches.
Answer:
Five plus the difference of seventeen and eight
Answer:
Correct answer: x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3
Step-by-step explanation:
Given:
3 x⁴ + 14 x² - 5 = 0 biquadratic equation
this equation is solved by a shift x² = t and get:
3 t² + 14 t - 5 = 0
t₁₂ = (-14 ± √14² - 4 · 3 · 5) / 2 · 3 = (-14 ± √196 + 60) / 6
t₁₂ = (-14 ± √256) / 6 = (-14 ± 16) / 6
t₁ = -5 or t₂ = 1 / 3
the solution t₁ = -5 is not accepted because it cannot be x² = -5
we accepted t₂ = 1 / 3
x² = 1 / 3 ⇒
x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3
