Mathematics

To find an angle you need to use trig ratios (tan, sin, and cos).

In this case to find ∠R you would need to use sin or cos because both of the legs are not across or adjacent to it.

To find ∠R you would need to do the "opposite" formula which would be (for sin) 5/13 <span>≈ 0.38.. asin = 22.26</span>

2x^3-3x^2+kx-1 is divided (x-1),the remainder is 2 find k
Debora [2.8K]

Answer:

k = 4

Step-by-step explanation:

if f(x) is divided by (x - h) then f(h) is the remainder

f(x) = 2x³ - 3x² + kx - 1

divided by (x - 1) , so h = 1 , then

2(1)³ - 3(1)² + k(1) - 1 = 2

2 - 3 + k - 1 = 2

- 2 + k = 2 ( add 2 to both sides )

k = 4

outputB= 3x+2

Find the input when the outputA is 3*outputB:

outputA=3outputB
