Dp calculus homework. need answers asap

2a) the # of terms are 11

2b) the term with x^3 is 262440x^3

Step-by-step explanation:

(x+3)^10 expansion: x^10+30x^9+405x^8+3240x^7+17010x^6+61236x^5+153090x^4+262440x^3+295245x^2+196830x+59049

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
