Complete Question:
<em>"Which pairs of points would result in a line with a rate of change of 2:1? select all that apply"</em>
<em>A.(−4,−11) and (−2−7)
</em>
<em>B.(5,6) and (−5, 12)
</em>
<em>C.(0,−3)and (−4,−11)
</em>
<em>D. (0,−3) and (5, 7)</em>
<em />
Rate of change is the slope. 2:1 would mean a slope of simply, 2.
We need to find slope of each of the choices from A - D and see which one has 2. The formula would be:
Where m is the slope and
x_1 is first x point
x_2 is second x point
y_1 is first y point
y_2 is second y point
Let's calculate slope of each of the choices.
A.
THis one is okay.
B.
THis one is not 2:1.
C.
THis one is okay.
D.
This one is okay.
Hence, A, C, and D all have rate of change of 2:1
Answer:
100 Cos 40° + 100 Sin 40° ≈ 141 yards
Step-by-step explanation:
From the diagram, side x is adjacent to the angle 40° while side y is the opposite to that same angle
This means that;
Cos 40° = x/100
x = 100 Cos 40°
Sin 40° = y/100
y = 100 Sin 40°
Therefore, total distance walked = x + y
" = 100 Cos 40° + 100 Sin 40° ≈ 141 yards
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Answer:
Oh cool! The answer is 90 since a and c or parallel, b cuts through them perpendicularly, forming a right angle.
