Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine rule
cosY = 
with x = 22, y = 20, z = 18
cosY = 
= 
= 
, then
Y = 
( ) ≈ 59.0° ( to the nearest tenth )
Answer:
12.42 = 1242 / 100;
4.6 = 46 / 10;
12.42 ÷ 4.6 = (1242 / 100) ÷ (46 / 10 ) = (1242 / 100) x (10 / 46 ) = ( 1242 / 46 ) x ( 100 / 10 ) = 27 x 10 = 270;
Step-by-step explanation:
Equation of the line is y = 4x + 4
Step-by-step explanation:
- Step 1: Given that the line passes through (2,4) and (1,0). Equation in slope-intercept form is y = mx + b
- Step 2: Find slope, m using the formula m = (y2 - y1)/(x2 - x1)
⇒ m = (0 - 4)/(1 - 2) = -4/-1 = 4
- Step 3: Find the y-intercept.
⇒ b = 4
- Step 3: Substitute the values in the equation
⇒ y = 4x + 4
Answer:
C
Step-by-step explanation:
y-intercept is not 1. It is -2
