Find all points having an x-coordinate of 5 whose distance from the point (2, 6) is 5

galina1969 [7]

Answer:

(5,2) and (5,10)

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

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

we have

$points\ (2,6),(5,y)\\d=5$

substitute in the formula

$5=\sqrt{(y-6)^{2}+(5-2)^{2}}$

solve for y

$5=\sqrt{(y-6)^{2}+(3)^{2}}$

$5=\sqrt{(y-6)^{2}+9}$

square both sides

$25=(y-6)^{2}+9$

$(y-6)^{2}=25-9$

$(y-6)^{2}=16$

square root both sides

$y-6=\pm4$

$y=6\pm4$

$y=6+4=10$

$y=6-4=2$

therefore

The points are

(5,2) and (5,10)

Use logarithmic properties and the fact that ln(2) ≈ 0.69 and ln(3) ≈ 1.10 to approximate the value of each of the

leva [86]

Answer:

The answer is 0.97

Step-by-step explanation:

Hi, we need to use the log properties taking into account that Ln(2) is aprox. 0.69 and Ln(3) is aprox. 1.10. I think you can understand better as we solve it, so here it goes.

$Ln(\frac{8}{3} )=Ln(8)-Ln(3)$

Since:

$8=2^{3}$

$Ln(2^{3} )-Ln(3)$

Then

$3Ln(2)-Ln(3)$

Now, we have everything where we want it, in terms of Ln(2) and Ln(3), now it is easy to solve.

$3(0.69)-1.10$

$2.07-1.10=0.97$

Best of luck.

What problems do they want? For 1and 2? Don’t need the answer on the paper just what’s the problem they are looking for?

KiRa [710]

For both problems, they want you to check their answers. For #1, is the opposite of -12 + 4 eight? For #2, can you split an 8 oz bag into 13 to have 2/3 oz in each bag? If you want the answers I’d be happy to comment. :)

Which system of linear equations will have the same solution as that of the given system of linear equations

Ksenya-84 [330]

Answer:

Option 1 is correct.

Step-by-step explanation:

Given two linear equations to us are ,

$\qquad 3x + 7y = 10 \\\\ \qquad x + y = 2$

And we have to find which system of linear equations have same answer .

On considering option (1) which is ,

$\qquad 3x + 7y = 10 \\\\ \qquad 2x + 2y = 4$

On taking the second equation in this ,

$=> 2x + 2y = 4 \\\\=> 2( x + y ) = 4 \\\\=> x+y =\dfrac{4}{2}}\\\\\boxed{\red{\bf => x + y = 2 } }$

This is same as the second one given in the Question . And the first one is already same .

<u>Hence</u><u> </u><u>option</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>is</u><u> </u><u>corre</u><u>ct</u><u> </u><u>.</u><u> </u>
