Answer:
1 and 2 are not congruent; 1 and 3 are congruent; 1 and 4 are congruent; 2 and 3 are not congruent; 2 and 4 are not congruent; 3 and 4 are congruent.
Step-by-step explanation:
From the diagram, we can see that the angle measures and side measures of figures 1, 3 and 4 are the same. This means that these three figures are congruent. Figure 2, however, is not congruent to any of the other 3.
Answer:
1.) 1-b, 2-a, 3-d, 4-c
Step-by-step explanation:
You recognize that the point-slope form of the equation for a line with slope m and point (h, k) is ...
... y - k = m(x - h)
____
Match this form to the given equations to determine (h, k). Once you determine (h, k) from the equation, find that point in the list of points to get your match-up. (All the slopes are correct, so you don't need to do any more work than just described.)
_____
For problems 3.) and 4.), use the above form with the given point and slope.
Answer:
B.) 18
Step-by-step explanation:
To find the correct b value we use this formula
b² - 4ac = 0
b = What we are solving for
a = 1
c = 81
b² - 4(1)(81) = 0
b² - 324 = 0
b² = 324

b = ±18
And 18 is one of the answer choices
So B.) 18 is the correct answer.
Answer:
The value of where a digit is in the number.
Step-by-step explanation:
Answer:
1.95 * 10^7
Step-by-step explanation:
19.5 million
write in standard notation
19500000
convert to scientific notation (by making the number such that the largest digit is in the one's place)
1.95 * 10^7
