If CDF = (3x + 14), FDE = (5x – 2), and CDE = (10x - 18)', find x.​

Answer:

x=2.83

Step-by-step explanation:

Through visual interpretation we get that,

CDF=FDE+CDE

Hence,

3x+14=5x-2+10x-18

3x-5x-10x=-14-2-18

-12x=-34

x=2.83

Assume Pina Colada Corp. uses the periodic inventory system and has a beginning inventory balance of $5800, purchases of $65000,
babymother [125]

The inventory account expected to have by December 31 is more than $5800. Option C

<h3>How to calculate the end inventory</h3>

The formula for end inventory is given as ;

Ending inventory = Beginning inventory + net purchases –sales

Beginning inventory = $5800

Net purchases = $65000

Sales = $112000

Put into the formula

Ending inventory = $ 5800 + 65000 - 112000

Add first,

Ending inventory = $ 70800 - 112000

Ending inventory = $ -41, 200

Thus, the inventory account expected to have by December 31 is more than $5800. Option C

18/34 as a reduced fraction
olya-2409 [2.1K]

I like to reduce everything by half if I don't already know the answer.

\frac{18}{34}  =  \frac{9}{17}

It just so happens that is the reduced fraction.

All I did was halve 18, which is 9, and halve 34, which is 17.

Nostrana [21]

Answer: 14.07\ m

Step-by-step explanation:

Given

Max is driving at a speed of 42\ mph

It took him three-quarters of a second i.e. 0.75\ s

Speed in meter per second is 18.77\ m/s

Distance is given by

d=v\times t

Reaction distance is

d=18.77\times 0.75=14.07\ m

Evaluate................
wolverine [178]

Answer:

h(8q²-2q) = 56q² -10q

k(2q²+3q) = 16q² +31q

Step-by-step explanation:

1. Replace x in the function definition with the function's argument, then simplify.

h(x) = 7x +4q

h(8q² -2q) = 7(8q² -2q) +4q = 56q² -14q +4q = 56q² -10q

__

2. Same as the first problem.

k(x) = 8x +7q

k(2q² +3q) = 8(2q² +3q) +7q = 16q² +24q +7q = 16q² +31q

_____

Comment on the problem

In each case, the function definition says the function is not a function of q; it is only a function of x. It is h(x), not h(x, q). Thus the "q" in the function definition should be considered to be a literal not to be affected by any value x may have. It could be considered another way to write z, for example. In that case, the function would evaluate to ...

h(8q² -2q) = 56q² -14q +4z

and replacing q with some value (say, 2) would give 196+4z, a value that still has z as a separate entity.

In short, I believe the offered answers are misleading with respect to how you would treat function definitions in the real world.

100 POINTS !!!! Let f(x)=√3x and g(x)=x-6 What's the smallest number that is in the domain of fog?
Gennadij [26K]

Answer:

6

Step-by-step explanation:

fog(x) = √3(x-6)

Domain => 3(x-6) ≥ 0

<=> x-6≥ 0

=> x ≥ 6

so, the smallest number is 6
