E. Acute
Step-by-step explanation:
Hope it helps
Plug in the values of x given in the domain:-
x + 5 = -4 + 5 = 1
-2 + 5 = 3 and so on
Are you sure you have the question right/ Because none of the choices are correct.
Answer:1 is the numerator 13 is the denominator
Step-by-step explanation:
Answer:
The directional derivative of f at A in the direction of
AD is 7.
Step-by-step explanation:
Step 1:
Directional of a function f in direction of the unit vector
is denoted by
,
.
Now the given points are
,
Step 2:
The vectors are given as
AB = (10-8, 9-9),the direction is
AC=(8-8,10-9), the direction is

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

Step 3:
The given directional derivative of f at A
is 9,

The given directional derivative of f at A
is 2,

The given directional derivative of f at A
is



The directional derivative of f at A in the direction of
is 7.
Answer:
Step-by-step explanation:
A)
the sum of any two sides of a right triangle more than any other side
14+15>29, x is less than 29
14+x>15
x>1
15+x>14
x>-1
1<x<29
lets use Pythagorean Theorem
14^(2)+15^(2)=c^2
196+225=c^2
421=c^2
plusminus sqrt(421)=c
distance can't be negative, so:
c=sqrt(421)
c=20.5182845287
sqrt(421) is the largest possible right triangle side
1<x
sqrt(421)
B) as we can see from above, the largest possible length of the third side is 14/sqrt(421) or about 20.5182845287ft
C)sqrt(421) by 14 by 15
tan(x1)=15/14
x1=tan^-1(15/14)
x1=47 degrees
tan(x2)=14/15
x2=tan^-1(14/15)
x2=43 degrees
