Write an equation of the line that passes through the given points.<br> question (-4, 3), (O, -10)

expeople1 [14]

Answer:

$Y=(\frac{4}{7}) x+2$

Step-by-step explanation:

$Y=mx+b$

$M=\frac{x2-x1}{y2-y1}$

$M=\frac{0-(-4)}{-10-3}$

$M=\frac{-4}{-7}$

$Y=(\frac{4}{7}) x+2$

After multiplying, a calculator screen displays the answer shown below. How would you write this number in standard form? Enter

Aliun [14]

Answer:

$8.234 E14=8.234 \times 10^{14}$

Step-by-step explanation:

The given number is $8.234 E14$

We need to write this number in standard form.

Any no is given in the standard form is given by :

$N=a\times 10^b$

Where

a and b is real no and integer

It means,

$8.234 E14=8.234 \times 10^{14}$

Hence, this is the required solution.

find a set of parametric equations of the line the line pases through the point (2,3,4) and is parallel to the xz-plane and the

joja [24]

Answer:

$x=2, y=3, z=4+t$

Step-by-step explanation:

For this case we need a line parallel to the plane x z and yz. And by definition of parallel we see that the intersection between the xz and yz plane is the z axis. And we can take the following unitary vector to construct the parametric equations:

$u= (u_x, u_y, u_z)= (0,0,1)$

Or any factor of u but for simplicity let's take the unitary vector.

Then the parametric equations are given by:

$x= P_x + u_x t$

$y= P_y + u_y t$

$z= P_z + u_z t$

Where the point given $P=(2,3,4)= (P_x , P_y, P_z)$

And then since we have everything we can replace like this:

$x= P_x + u_x t 2+ 0*t = 2$

$y= P_y + u_y t= 3+ 0*t = 3$

$z= P_z + u_z t = 4+ 1t = 4+t$

$x=2, y=3, z=4+t$

Evan, Claire, Jaya and Tim are running a 3km relay race.

Kruka [31]

Answer:

Tim needs to finish 59/90

Step-by-step explanation:

Add together what Evan Claire and Jaya ran

9/10 + 7/9+ 2/3

The common denominator is 90

9/10 (9/9) +7/9 *10/10 + 2/3 *30/30

81/90 + 70/90 + 60/90

211/90

We need 3 km = 3 *90/90 = 270 /90

270/90 - 211/90 = 59/90
