Find the distance between each pair of points <br>L(-7,0) ,Y(5,9)​
Sedbober [7]

Answer:  The distance is 15

Step-by-step explanation:

To find the distance between L and Y find the difference in the x and y coordinates then square them and add them to find their square root.

-7-5= -12

0-9 = -9

12^2 + 9^2 = d^2   where d is the distance

144 + 81 = d^2

225 = d^2

d= \sqrt{225}  

d= 15

What is AE?<br> Enter your answer in the box?
Nataly [62]

Answer:

AE = 18 units

Step-by-step explanation:

Δ AEB and Δ DEC are similar , then corresponding sides are in proportion, that is

\frac{AE}{DE} = \frac{AB}{DC} , substitute values

\frac{2x+4}{x+8} = \frac{12}{10} ( cross- multiply )

10(2x + 4) = 12(x + 8) ← distribute parenthesis on both sides

20x + 40 = 12x + 96 ( subtract 12x from both sides )

8x + 40 = 96 ( subtract 40 from both sides )

8x = 56 ( divide both sides by 8 )

x = 7

Then

AE = 2x + 4 = 2(7) + 4 = 14 + 4 = 18 units

50 is 20% of what ? Round to the nearest tenth is needed
miv72 [106K]

Answer:

250

Step-by-step explanation:

20% of 250 is 50. 100% of 250 is 250, therefore 20 percent of 250 equals 50.

More simplified explanation: The question is asking if 50 is 20% of a number, what is the number? So we know that 20% is 1/5 of 100%; if we know that 50 is 20% of something, then we would multiply 50 by 5 to get the answer. We would have to multiply 50 by 5 because if 50 is 20% of a number that would mean that 50 is 1/5 of the number we need to find, so to find the number, you to multiply 50 by 5.

Hope this helps!

Create an explicit formula of the sequence. 7, 14, 28, 56, ..., Find the 10th term of the sequence. Complete your work in the sp
White raven [17]

Answer:

  an = 7·2^(n-1)

  a10 = 3584

Step-by-step explanation:

(a) The terms of the sequence do not have a common difference, but they do have a common ratio. That ratio is 14/7 = 2. The general term of a geometric sequence with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

For a1=7 and r=2, the explicit formula is ...

  an = 7·2^(n-1)

__

(b) The 10th term is ...

  a10 = 7·2^(10 -1) = 7·512

  a10 = 3584
