Find cos(B) in the triangle.
Step-by-step explanation:
[tex] \cos( \beta ) = \frac{5}{13} = 0.385[/tex]
Cos (B) in the right angled triangle is 5/13 .
Given,
Right angled triangle .
Now,
In right angled triangle
Perpendicular = 12
Base = 5
Hypotenuse = 13
So,
According to trigonometric functions,
CosФ = base / hypotenuse
sinФ = perpendicular / hypotenuse
tanФ = perpendicular / base
So,
Substitute the value in the function of cos,
Cos(B) = base / hypotenuse
Cos(B) = 5 / 13
Thus the value of function cos (B) is 5/13 .

DOGS During a recent visit to the veterinarian's office, Mrs. Cho was informed that a healthy weight for her cat is approximately 35 pounds, plus or minus three pounds. Write an absolute value inequality that represents healthy weights w for her dog.
Answer:
Step-by-step explanation:
from the given information:
The healthy weight of the cat = 35 pounds
with +/- 3
To write the absolute value;
The healthy weight will either be less or greater.
So; w > 35 +3 or w < 35 - 3
w - 35 > 3 or w - 35 < -3
Thus, the healthy weight will be |w - 35| > 3

A) f (x) = (x-5) (x+8)
B) f (x) = 2 (x-5) (x+8)
C) f (x) =2 (x+5) (x-8)

Answer:
A
Step-by-step explanation:
since your in hurry i wont be showing work
Answer: B
is B f(x) = 2 (x-5) (x+8)
Step-by-step explanation:
Because you simplify
f (x) = 2x² + 6x - 80
f (x) = 2x2+6x−80
f (x) = 2x2+6x−80
= 2 (x−5)(x+8)

The area of the sector which is the white triangle adding the shaded region is 68.9/360*π*9.28^2=51.78005(rounding to 5th digit after decimal point for accuracy before we do final round for answer)
The area of the white triangle in the sector has area 1/2*9.28^2*sin(68.9)= 40.17223(rounding to 5 digits again for some accuracy.
Now we take out the white triangle from the sector.
51.78005-40.17223=11.60782
rounding to the nearest tenth we get 11.6 cm^2

Help Me On Both Of These Qestions Please.
Answer:
3) m∡ACB = 40 m∡ABC = 63
4) m∡BCA = 14 m∡ABC = 83
Step-by-step explanation:
Since DE is a line it has 180 degrees so:
103 + CAB = 180
CAB = 77 degrees
All triangle interior angles of a triangle add up to 180 degrees, so:
BAC + ACB + CBA = 180
3x - 14 + 3x + 9 + 77 = 180
6x + 72 = 180
6x = 108
x = 18
Plug in your values:
3(18) - 14 = 40
3(18) + 9 = 63
Use the same method for the next problem.

The sale price of an item is $330 after a 25% discount. What was the original price of the item?
Answer:
The original price of the item is $440.
Step-by-step explanation:
If you have a discount for 25% and the resulting price is 330, then 330 is 75% of the original price.
Because of the way my brain works, my first thought was that if $330 is 75% of the original price then, 1/3 of 330 would be 25% of the original price. So, I multiplied 330 by 1/3 and got 110. Then I added 110 and 330 to get 440, the original price.

A contractor must haul a large amount of dirt to a work site. She collected information from two hauling companies. EX Excavation gives its prices in a table. Happy Hauling Service gives its prices in a graph.
Answer:
$24.5
Step-by-step explanation:
Its $24.5 for the rate of change for EZ Excavation
The EX Excavation will charge $980 for 40 cubic yards of dirt.
What is unit rate?A unit rate means a rate for one of something.
Given a graph showing cost for per cubic yard of dirt.
The unit rate = 196/8 = 490/20 = 637/26 = 24.5
Therefore, for 40 cubic yards of dirt = 40*24.5 = 980
Hence, The EX Excavation will charge $980 for 40 cubic yards of dirt.

Find the missing side of each triangle.
Answer:
x = 2√5
Step-by-step explanation:
Using the Pythagorean Theorem:
a² + b² = c²
You can identify that x is the hypotenuse, as it is opposite to the right angle.
So:
3² + √11² = x²
9 + [(√11) (√11)] = x²
9 + 11 = x²
20 = x²
√20 = √x²
√4√5 = x
2√5 = x
x = 2√5
