A line passes through (8,2) and (11,-13) write the equation of thr line in standerd form
docker41 [41]

Answer:

Step-by-step explanation:

(8,2),(11,-13)

slope(m) = (-13 - 2) / (11 - 8) = -15/3 = -5

y = mx + b

slope(m) = -5

(8,2)...x = 8 and y = 2

now we sub and find b, the y int

2 = -5(8) + b

2 = -40 + b

2 + 40 = b

42 = b

so ur equation is : y = -5x + 42...now we need it in standard form

Ax + By = C

y = -5x  42

5x + y = 42 <====

Geomertric sequence- A bank account earns a constant rate of interest each month. The account was opened on March 1 aith $18,000
kifflom [539]
A₀ = 18 000(1 + 0.0025)⁰
A₁ = 18 000(1 + 0.0025)¹
A₂ = 18 000(1 + 0.0025)²
A(n) = 18 000(1 + 0.0025)ⁿ

So, after 5 months, A(n) = 18 000(1 + 0.0025)⁵ = $18 226.1278 ≈ 18 226.13

5 years is 60 months.

A₆₀ = 18 000(1 + 0.0025)⁶⁰ = $20 909.1021  ≈ $20 909.10

1. Sarah applies the pearl guitar fret markers to her fret board as shown. Each fret marker is in the shape of a parallelogram.
Flura [38]

Answer:

315

Step-by-step explanation:

We are told in the question that each fret marker is in the shape of a parallelogram

The area of a parallelogram is given as

Base × Height.

Each of the bottoms of the fret markers has the following values

Base = 52.5mm

Height =6 mm

The area of each of the bottom fret markers

= Base × Height

= 52.5 × 6

= 315

Therefore, the area of each of the bottom fret markers without unit is 315
