Find the slope of the line that contains (-1,9) and (9,9)

Answers

Steps:
1. Do the slope formula
Y2-Y1
--------
X2-X1
2.
9-9
------
9- (-1)
3. 9-9=0
9 + 1=10
4. 0/10 = 0
5. Your answer is 0
0 becuase the slope of a line is the amount of one y to another and both y's are 9 so there is no slope.

The directional derivative of f at A in the direction of the vector AB is 9 and the directional derivative at A in the direction of

AC is 2. Find the directional derivative of f at A in the direction of the vector AD.

(Round your answer to two decimal places.)

Answers

Answer:

The directional derivative of f at A in the direction of \vec{u} AD is 7.

Step-by-step explanation:

Step 1:

Directional of a function f in direction of the unit vector \vec{u}=(a,b) is denoted by D\vec{u}f(x,y),

D\vec{u}f(x,y)=f_(x)\left ( x ,y\right ).a+f_(y)(x,y).b.

Now the given points are

A(8,9),B(10,9),C(8,10) and D(11,13),

Step 2:

The vectors are given as

AB = (10-8, 9-9),the direction is

\vec{u}_(AB) = (AB)/(\left \| AB \right \|)=(1,0)

AC=(8-8,10-9), the direction is

\vec{u}_(AC) = (AC)/(\left \| AC \right \|)=(0,1)

AC=(11-8,13-9), the direction is

\vec{u}_(AD) = (AD)/(\left \| AD \right \|)=\left ((3)/(5),(4)/(5) \right )

Step 3:

The given directional derivative of f at A \vec{u}_(AB) is 9,

D\vec{u}_(AB)f=f_(x) \cdot 1 + f_(y)\cdot 0\nf_(x) =9

The given directional derivative of f at A \vec{u}_(AC) is 2,

D\vec{u}_(AB)f=f_(x) \cdot 0 + f_(y)\cdot 1\nf_(y) =2

The given directional derivative of f at A \vec{u}_(AD) is

D\vec{u}_(AD)f=f_(x) \cdot (3)/(5) + f_(y)\cdot (4)/(5)

D\vec{u}_(AD)f=9 \cdot (3)/(5) + 2\cdot (4)/(5)

D\vec{u}_(AD)f= (27+8)/(5) =7

The directional derivative of f at A in the direction of  \vec{u}_(AD) is  7.

If 0.46 meter is cut from a 12 meter steel rod, how long is the steel rod after the cut?

Answers

The answer is 11.54 because 12.00 -00.46 is 11.54
The answer should be 11.54 because if you decrease 0.46 from 12 thats what you get

Apartment A rents for $600 per month and includes heat and electric. Apartment B rents for $400 per month but heat and electric are not included. Electric averages $40 per month. Heat costs for last year totaled $800. Which apartment is cheaper?

Answers

Appartment B is cheaper. Explanation: we need to compare these two values. A = 600 and B = 400 + cost of heat per month + cost of electricity per month. The cost of heat per year is 800, which gives us a monthly cost of 800/12 = ~$67. So the rent cost for appartment B is 400 + 40 + 67 or 507, which is less than 600.

Which measurement is not equivalent to the others?36 inches
3 feet
1/100 of a mile
1 yard

Answers

If you would like to know which measurement is not equivalent to the others, you can calculate this using the following steps:

1 yard = 3 feet
1 foot = 12 inches
1 mile = 5280 feet

3 feet = 3 * 12 inches = 36 inches

1 yard = 3 feet = 36 inches

1/100 of a mile = 1/100 * 5280 feet = 52.8 feet 

Not equivalent: 1/100 of a mile.
