when you graph the equation the horizontal line is on Y=0 & 20
answer y=0 & Y=20
Answer:
A. DEF where and .
Step-by-step explanation:
At first we must keep in mind that two triangles are similar when they have same angle configuration, that is, each pair of angles is congruent. If ABC and DEF, then and . Hence, and .
In a nutshell, correct answer is A.
-10.5 deg
Yesterday's temp = 7-1/2 deg (or 7.5 deg)
Today's temp = -3 deg
net change = today's temp - yesterday's temp
= -3 - 7.5 = -10.5 deg
40°, 60°, and 80°
We know that the sum of the angles of a triangle is equal to 180°.
We can use this equation to solve for these angles:
180 = 2x + 3x + 4x
180 = 9x
20 = x
Then substitute the solution in for x to solve for the angles:
2(20) = 40°
3(20) = 60°
4(20) = 80°
Therefore, the angles are 40°, 60°, and 80°.
y-values of sampled wave:
0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1
My teacher told me to put a dot on very cross or intersection that the line is on.
