Answer:
y = - 3x + 11
Step-by-step explanation:
the altitude is a line from the vertex A drawn perpendicular to the opposite side BC
calculate the slope of BC using the slope formula
m =
with (x₁, y₁ ) = B (- 7, 3 ) and (x₂, y₂ ) = C (- 1, 5 )
= = = =
given a line with slope m then the slope of a line perpendicular to it is
= - = - = - 3
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then
y = - 3x + c ← is the partial equation
to find c substitute A (4, - 1 ) into the partial equation
- 1 = - 12 + c ⇒ c = - 1 + 12 = 11
y = - 3x + 11 ← equation of altitude from A
I think it’s d! I’m not too sure but Ide do with d
Answer:
r = 3 in.
Step-by-step explanation:
vol = Bh where B is the area of the base and h is the height of the cylinder
The base is a circle so
B = h = 5
141.3 = 3.14(5)
= 15.7
= 141.3/15.7 = 9
r = 3 in.

D.
Answer:
Calculate the slope in the four intervals with the formula
m = (f(b) - f(a)) / (b - a) slope in Intervall [a; b]
m1 = (3 - 0) / (2 - 0) = 1.5
m2 = (11 - 3) / (4 - 2) = 4
m3 = (23 - 3) / (6 - 2) = 5
m4 = (23 - 11) / (6 - 4) = 6
between x = 4 and x = 6 is the correct answer.
