Given the graph of a line y=−x. Write an equation of a line which is perpendicular and goes through the point (8,2).

coldgirl [10]

Answer:

y = x - 6

Step-by-step explanation:

The slope of y = -x is -1, so the slope of any line perpendicular to y = -x is +1. Thus,

y = mx + b becomes 2 = 1(8) + b, so that b = -6.

The desired equation is y = x - 6.

Check: Does (8,2) lie on this line? Is 2 = 8 - 6 true? YES.

A toy rocket launched into the air has a height ( h feet) at given time ( t seconds) as h= -16^2+160t until it hits the ground.

Gennadij [26K]

Answer:

$t = \frac{53}{32}$

Step-by-step explanation:

$h=\:-16^2+160t$

$9=\:-16^2+160t$ $substitute$

$-16^2+160t=9$

$-256+160t=9$

$-256+160t+256=9+256$

$160t=265$

$\frac{160t}{160}=\frac{265}{160}$

$t=\frac{53}{32}$

At $\frac{53}{32}$ seconds it is at a height of 9 ft.

BlackZzzverrR [31]

Answer:

10.55%

Step-by-step explanation:

Given:

Initial weight of the new born baby = 3,874 grams

final weight of the baby = 3,465 grams

Now,

the current percentage of the weight loss will be calculated as:

Weight loss percentage = $\frac{\textup{Loss in the weight}}{\textup{Initial weight of the baby}}\times100$ %

on substituting the respective values, we get

Weight loss percentage = $\frac{(3874-3465)}{3874}\times100$ %

Weight loss percentage = 10.55%
