(9,5) and (4,-7) find the distance between two points

Pani-rosa [81]

Answer:

13 units

Step-by-step explanation:

Use the distance formula, d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$ , where (x2, y2) and (x1, y1) are two different points on the line.

Plug in the values:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

d = $\sqrt{(9 - 4)^2 + (5 + 7)^2}$

d = $\sqrt{5^2 + 12^2}$

d = $\sqrt{25 + 144}$

d = $\sqrt{169}$

d = 13

find the sum of a 9-term geometric sequence when the first term is 4 and the last term is 1,024 and select the correct answer be

olasank [31]

Hello,

$u_{1} =4\\
 u_{2} =4*q\\
 u_{3} =4*q^2\\
...\\

 u_{9} =4*q^8\\\\
==\textgreater\ 4*q^8=1024\\
==\textgreater\ q^8=256\\
==\textgreater\ q=2\mbox{( and there is a problem in the question) } \ or \ q=-2\\
if\ q=2 \ then\ \sum_{i=0}^{8}\ 4*(2)^i= 4*\dfrac{1-2^9}{1-2} =2044\\

if \ q=-2 \ then\ \sum_{i=0}^{8}\ 4*(-2)^i= 4*\dfrac{1-(-2)^9}{1+2} =684\\

B is true; pi= ~3.14. 3+4 is equal to 7, so because pi is greater than 3, pi+4>7

To the nearest square centimeter, what is the area of the circle below? Use pi = 3.14

Mademuasel [1]

Answer:

$radius \: \: r = 5 \: cm \\ area = \pi {r}^{2} \\ = 3.14 \times (5) {}^{2} \\ = 78.5 \: {cm}^{2}$
