Find the equation of the line perpendicular to the given line, through the given point x=-3; (1,8)
Bumek [7]

Answer:

y = 8

General Formulas and Concepts:

<u>Algebra I</u>

Coordinates (x, y)

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

[Line] x = -3

Point (1, 8)

<u>Step 2: Find Perpendicular Line</u>

<em>A vertical line's slope is undefined. </em>

The negative reciprocal of an undefined slope is 0.

  1. Define perpendicular slope:                                                                          <em>m</em> = 0
  2. Substitute in <em>m</em> [Slope-Intercept Form]:                                                          y = 0x + b
  3. Simplify:                                                                                                               y = b

Given point (1, 8), our <em>y</em>-value is equal to 8.

∴ the perpendicular line is y = 8.

A rocket is shot straight into the air at an initial velocity of 70 feet/second.
DanielleElmas [232]

Answer: 245 feet

Step-by-step explanation:

Given: The height of the rocket after t seconds is represented by the formula:

h=70t-5t^2

\dfrac{dh}{dt}=70-10t  [Differentiate both sides w.r.t. t]

Put

\dfrac{dh}{dt}=0\\\\\Rightarrow\ 70-10t=0\\\\\Rightarrow\ t=\dfrac{70}{10}=7

Also, \dfrac{d^2h}{dt^2}=-10 i.e. height is maximum at t=7.

Maximum height = h=70(7)-5(7)^2 = 490 - 245= 245\text{ feet}

Hence, the maximum height the rocket reaches = 245 feet.

-6h plus 4 - 3plus h equals 11
olga55 [171]

- 6h + 4 - 3 + h = 11
So we start by combining like terms;
- 6h + h =  - 5h
4 - 3 = 1
Now we have;
- 5h + 1 = 11
We then subtract 1 from both sides;
- 5h + 1 = 11
- 5h = 10
Then we divide both sides by 5;
- 5h = 10
- 5h \div  - 5h =  h
10 \div  - 5h =  - 2
Leaving the final answer to be h = -2
