Answer:
AB = 4.41
Step-by-step explanation:
→You are given the adjacent side and need to find the hypotenuse. For this, we use cos.
<u>→Set it up, like so:</u>
<u />
<u>→To get rid of the x in the denominator, multiply everything by x:</u>
<u />
<u>→Divide both sides by cos25:</u>
x = 4.413
<u>→Round to nearest hundredth:</u>
x = 4.41
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (4, - 3)
m = =
= -1, hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 2), then
2 = 1 + c ⇒ c = 2 - 1 = 1
y = - x + 1 ← equation in slope- intercept form
