Jason had to determine the solution set of x squared + StartFraction y squared Over 49 EndFraction greater-than 1. Examine the graph he drew. On a coordinate plane, a dotted line ellipse has center (0, 0) and goes through (0, 7), (1, 0), (0, negative 7), and (1, 0). Which element, if any, is incorrect in the graph? The graph is correct. The boundary should be a solid line. The major axis should be horizontal. The shaded region that represents the solution set should be inside the ellipse.

a

step-by-step explanation:

the answer is a

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

answer: 0.64

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
