Answer:

first answer is 7 square root 2, second is 39, third is 5.36487494991.

Step-by-step explanation:

1st answer: its a right triangle with both sides as 45 degrees no shorter legs or longer legs. so both opp and adj legs are equal to 7. 7 times 7 plus 7 times 7 is 98 so square it into radical form and get 7 square root 2. second is 39 because of the 3,4,5. 15 36 and 39 are ratios of the rule. Third is 5.45454545... because make a triangle with a right triangle properties. name the hyp variable A. Find each angle which is 90, 56 ( the top of the triangle where plane is ) and 34 ( at the boat place ). You use Sine with 34 which is (0.55919290347...). This is equal to 3 km over A. Change the form and turn it into A=3 divided by 0.55...) which is 5.36487494991.

X=|y| what is the domain and range ?

cricket20 [7]

Answer:

Domain: x ≥ 0

Range: All real numbers

Step-by-step explanation:

This is an absolute value function which creates a V for its graph. Since the absolute value is on y, the function is rotated to the right or sideways.

This means only the x values of 0 and greater are used in the function. Since the domain is the set of all x values then it is x≥0.

This also means that all y values are used on the y-axis. There is no restriction on the y values. Since the range is the set of all y values then it is all real numbers.

What are the solutions to

Svetllana [295]

Answer:

B and F

Step-by-step explanation:

Given

x² + 4x + 4 = 12 ( subtract 4 from both sides )

x² + 4x = 8

Using the method of completing the square to solve for x

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 8 + 4, that is

(x + 2)² = 12 ( take the square root of both sides )

x + 2 = ± $\sqrt{12}$ ( subtract 2 from both sides )

x = ± $\sqrt{12}$ - 2

= ± 2 $\sqrt{3}$ - 2

Hence

x = 2 $\sqrt{3}$ - 2 → B

x = - 2 $\sqrt{3}$ - 2 → F

A small business makes 3-speed and 10-speed bicycles at two different factories. Factory A produces 16 3-speed and 20 10-speed b

GarryVolchara [31]

Answer:

Factory A should be operated 6.11 days

Factory B should be operated 6.88 days

The minimum cost for factory A is $6,110

The minimum cost for factory B is $5,504

Step-by-step explanation:

Factory A

Daily production: 16 3-speed and 20 10-speed bikes

Total daily production = 16+20 = 36 speed bikes

Order: 80 3-speed and 140 10-speed bikes

Total order = 80+140 = 220 speed bikes

Number of days = 220/36 = 6.11 days

Cost per day = $1,000

Minimum cost for 6.11 days = $1000 × 6.11 = $6,110

Factory B

Daily production: 12 3-speed and 20 10-speed bikes

Total daily production = 12+20 = 32 speed bikes

Total order = 220 speed bikes

Number of days = 220/36 = 6.88 days

Cost per day = $800

Cost for 6.88 days = $800 × 6.88 = $5,504
