Find the coordinates of point b on ac such that the ratio of AB to BC is 2:1

Mathematics
1 answer:
AnnyKZ [126]3 years ago
3 0

Answer:

(-2, 3)

Step-by-step explanation:

The point B is:

B(x,y)

x

AB(A to B) is twice BC(B to C)

AB is 2 - x. BC is x - (-4) = x + 4.

So

2 - x = 2(x + 4)

2 - x = 2x + 8

3x = -6

x = -2

y

Same logic as above.

AB is -5 - y. BC is y - 7.

-5 - y = 2(y - 7)

-5 - y = 2y - 14

3y = 9

y = 3

The point is (-2, 3).

Find the output, f, when the input, t, is 7.<br> f = 2t - 3f=2t−3
ella [17]

Answer:

f = 3 1/2

Step-by-step explanation:

f = 2t - 3f     Substitute 7 for t

f = 2(7) - 3f   Multiply

f = 14 - 3f

+3f     + 3f    Add 3f to both sides

4f = 14          Divide both sides by 4

f = 3 1/2

I need help with this please
Lelechka [254]

There are 36 possible combinations that can occur when 2 dice are rolled. For the sake of this question, we'll count instances where dice 1 = 3/dice 2 = 2 and dice 1 = 2/dice 2 = 3.

Now, let's think about all of the possible ways a total of 5 could be rolled.

1 + 4

2 + 3

3 + 2

4 + 1

That's 4 possibilities to roll a total of 5 out of 36 possible outcomes.

4 / 36 = ? / 180

---Now, we need to use a proportion in order to figure out the possibilities out of 180.

36x = 720

x = 20

If you rolled a pair of fair dice 180 times, you would expect to roll a total of 5, 20 times.

Hope this helps!

Solve for x.<br> 7 inches<br> Х<br> 11 inches
jonny [76]

Answer:

8.49 inches

Step-by-step explanation:

x^2 + 7^2 = 11^2

x^2 + 49 = 121

X^2 = 121 - 49

x^2 = 72 (then take square root on both sides)

x = 8.49 inches
