The angle subtended by a diameter is always right. That's Thales' Theorem, one of the first in geometry. We conclude y=90°.
The angle subtended by an arc is half the arc length, so z=50°.
The angles in a triangle add to 180°, so x = 180° - y - z = 40°.
Answer: x=40°, y=90°, z=50°
Answer:
Third choice: y + 7 = -2(x - 3)
Step-by-step explanation:
One of the two given points is (3, -7): (h, k), which would be the given point in the point-slope form of the equation of a straight line:
y - k = m(x - h)
If we replace h with 3 and k with -7, we get
y + 7 = m(x - 3).
Next, let's calculate the slope, m: as we go from (2, -5) to (3, -7), x increases by 1 and y decreases by 2. Hence, the slope is m = rise / run = -2/1, or -2.
Thus, the third answer choice is the correct one: y + 7 = -2(x - 3).
She is right its ( is not) just took the test
Answer:

Step-by-step explanation:
First, let’s check to see if the direction vector is a unit vector:

It’s not a unit vector. therefore let's divide the vector by its magnitude in order to convert it into a unit vector:

Now, the directional derivative is given by:

So let's calculate the partial derivates:



Therefore:

No sam is not correct because Mia ran .10 and Sam ran .05 And although .05 may seem bigger .10 is more expressed That is the answer I think
