if a line segment has endpoint A(3x+5,3y) and B(x-1,-y), what are the coordinates of the mid point of line AB

1 answer:

7 0

Midpoint formula - <u> $\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$ </u>
$
\left(\dfrac{3x+5+x-1}{2},\dfrac{3y-y}{2}\right)=\\
\left(\dfrac{4x+4}{2},\dfrac{2y}{2}\right)=\\
(2x+2,y)$

Mark studies a group of 30 whales. If each whale weighed approximately 3.8 x 105 pounds, find the total weight of all 30 whales.

Yakvenalex [24]

Answer:

$= 1.14 \times 10^{7}pounds$

Step-by-step explanation:

If each whales weighed

$3.8 \times {10}^{5}$

Then 30 whales weighed

$30 \times 3.8 \times {10}^{5}$

$=114 \times {10}^{5}$

$= 1.14 \times 10^{2} \times {10}^{10}$

Applying the law of indices we obtain

$= 1.14 \times 10^{(2+ 5)}$

$=1.14 \times 10^{7}pounds$
