The vertices of an isosceles triangle are a(-10, 1), b(-6, 3) and c(-4, 7).

what is the equation of the triangle's line of symmetry?

y = -x - 3
y = -x + 3
y = x + 3
y = x - 3

step-by-step explanation:

i just know the internet

(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.

answer: c. im 100 percent sure
