How do I find the value of k

Mathematics
1 answer:
goblinko [34]2 years ago

So you have to find the equation of the line of both then find the value of k

so f(x) points are (0,1) and (2,6)

hopefully you know how to find a equation of a line between two points
if not i can explain after, most people just want the answer here anyways

y=5/2<span>x+1
</span>
g(x) points  (0,-1) and (2,4)
<span>y=3x-2
</span>
g(x) =  f(x) + k

5/2x-1= 5/2x+1 + k 
so k = -2

hope this helps

Explain why 2n+1 must be an odd number
Lorico [155]
If is an integer (a whole number), then the expression represents an even number, because even numbers are the multiples of 2. The expressions 2 n − 1 and 2 n + 1 can represent odd numbers, as an odd number is one less, or one more than an even number.

ecn 221 The sodium content of a popular sports drink is listed as 206 mg in a 32-oz bottle. Analysis of 14 bottles indicates a s
spayn [35]

Answer:

H_{0}: \mu = 206\text{ mg}\\H_A: \mu \neq 206\text{ mg}

Step-by-step explanation:

We are given the following in the question:

Population mean, μ =  206 mg

Sample mean, \bar{x} = 217.5 mg

Sample size, n = 14

Sample standard deviation, s = 14.9 mg

Claim:

The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.

Thus, we design the null and the alternate hypothesis

H_{0}: \mu = 206\text{ mg}\\H_A: \mu \neq 206\text{ mg}

We use two-tailed t test to perform this hypothesis.

I cannot figure this question out
uysha [10]

Answer:

1/12

Step-by-step explanation:

you need to make sure that they have a common denominator before doing anything.

Find the lowest common multiple (lcm), which would be 12 (3 x 4 = 12)

So then, put 12 as both denominators, and subtract.

7/12 - 9/12 is equal to 28/12 - 27/12, because 3 miltiplied by 4 equals 12, therefore you mutiply the 7 by the 4, and 4 miltiplied by 3 equals 12, therefore you multiply the 9 by the 3.


Sorry if this is confusing, i tried explaining as best i could! Hope this helped!

How much 20% solution needs to be added to a 60% solution to make 400 ml of a 40% solution
Scorpion4ik [409]

Let x be the volume of 20% solution, y the volume of the 60% solution. We want a total volume of 400 mL in the final mixture, so

x+y=400

Each mL of either solution will contribute a corresponding concentration, and in the final mixture we want the 400 mL to have a 40% concentration, which means we should also have

0.2x+0.6y=0.4\times400=160

Solve the system and we get x=y=200\,\rm{mL}.
