HOW do you find the value of TAN 88 degrees 22' 45'' and COT 36 degrees???
storchak [24]
Part 1
We want to find the tan of 88 degrees, 22' 45''.

88° 22' 45''
= 88 + 22/60 + 45/3600 degrees
= 88.3792°

From the calculator, obtain
tan(88.3792°) = 35.3409

Answer: 35.3409

Part 2
We want to find cot(36°).

By definition, cot(x) = 1/tan(x).
From the calculator, obtain
tan(36°) = 0.7265
Therefore
cot(36°) = 1/0.7265 = 1.3764

Answer: 1.3764

Let f(x) be a continuous function such that f(1) and f'(x)-Vx3 + 6. What is the value of,f(5)? (A) 11.446 (C) 24.672 (B) 13.446
tia_tia [17]

Answer:

f(5) = 26.672 which is option D

Step-by-step explanation:

From question, f(1) = 2 and f'(x)=√(x^3 + 6)

f(5) = f(1) + (5,1)∫ f'(x) dx

Integrating using the boundary 5 and 1;

f(5) = 2 + (5,1)∫√(x^3 + 6) dx

f(5) = 2 + 24.672

So f(5) = 26.672

The length of a rectangle is 5 more than twice the width. the perimeter is 130 inches. what is te area
Brut [27]
The length of a rectangle:
L =  2 W  + 5
The perimeter:
P = 2 L + 2 W
130 = 2 · ( 2 W + 5 ) + 2 W
130 = 4 W + 10 + 2 W
130 - 10 = 6 W
120 = 6 W
W = 120 : 6
W = 20 in
L = 2 · 20 + 5
L = 40 + 5
L = 45 in.
Finally the area:
A = L · W
A = 20 · 45
A = 900 in²

What is 5(4x+12)+3x+2
yulyashka [42]

Answer:

23 x + 62

Step-by-step explanation:

Simplify the following:

5 (4 x + 12) + 3 x + 2

5 (4 x + 12) = 20 x + 60:

20 x + 60 + 3 x + 2

Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):

(20 x + 3 x) + (60 + 2)

20 x + 3 x = 23 x:

23 x + (60 + 2)

60 + 2 = 62:

Answer:  23 x + 62
