Find an exponential function of the form f(t) = ygb' for these data, in which t =0 corresponds to 2000, f(t) is in millions.f(t)=() (Use intecers or decimals for any numbers in the expression. Round to four decimal places as needed.)(b) What is the projecled population in ...
Function that best describe the graph: Based on the graph there are four zeros of the polynomial function which are the values of {eq}x {/eq} that intersecting the x-axis, two of them are negative and two are positive.Thus what we are going to do is fin...
Which pattern of numbers represents a linear equation: 3, 9, 15, 21, 27, 33; 7, 5, 9, 3, 17, 1; 1, 3, 1, 3, 1, 3; 2, 4, 8, 16, 32, 64? What is the nth term of a sequence? In the term x^y, which term is the exponent?
Inline exception: use \$ to escape, and therefore use, a dollar sign in an equation ($(\$4.00 - \$1.50 = \$2.50)$): $($4.00 - $1.50 = 2.50 ) Inline exception 2: use <span>$</span> for inline use of dollar sign before a math expression. Block example: $$ x = {-b \...
After solving a rational equation, why is it important to check your answer? How is this done? What happens if you are checking a solution for the rational expression and find that it makes one of the denominators in the expression equal to zero?
Pressure increase in a water body follows the linear equation for vertical pressure variation (Equation 1) ∆P = ρ⁎g ⁎∆h (1) where ΔP represents the variation in pressure, ρ is the density of seawater, g is gravity and Δh is the difference in depth. Marine life in the ...
Q13) When solving a quadratic equation of the form ax² + bx + c = 0, which formula should be used to find the roots? A) Discriminant formula: x = (-b ±√(b² - 4ac)) / (2a) B) Vertex formula: x = -b / (2a) ...
Which of the following tables represents values of (x, y) that satisfy the equation? y = -6x^2 - 24x - 1 What are one-to-one and onto functions? Explain with example. Explain what it means for two functions that agree at all but one point. ...
