Answer:

11.4 x 10 ^ 6

Step-by-step explanation:

  1. First, you have to convert 3.8 x 10^5 out of scientific notation. To do that, multiply 3.8 * 10^5, you'll get 380,000. This is the weight of each whale.
  2. Now multiply the weight of each whale times 30. 380,000 * 30 = 11,400,000
  3. Convert back to scientific notation. 11.4 x 10^6

Two perpendicular lines intersect on the -axis. The equation of one line is y- 4x-6=0. Determine the equation of the other line.
Kay [80]

Answer:

y = -\frac{1}{4}x + 6 or y = -\frac{1}{4}x - 0.375

Step-by-step explanation:

For 2 lines to be perpendicular, their slopes must be <u>negative reciprocals</u>. In order to find the perpendicular of y - 4x - 6 = 0:

SLOPE INTERCEPT FORM: y = 4x + 6

SLOPE OF LINE A: m=4

SLOPE OF LINE B (the one you are looking for): m=-\frac{1}{4}

Since I don't know if you meant that they intercept on the x or y axis I will do both.

<u>y-axis</u>

y-6=-\frac{1}{4}(x-0)

y = -\frac{1}{4}x+6

<u>x-axis</u>

y-0=-\frac{1}{4}(x-1.5)

y=-\frac{1}{4}x-0.375
