By using concepts of logarithms and powers, the concentration of hydrogen ions in a volume of a liter of a sports drink with a pH of 2.5.

Logarithms are trascendental equations, that is, expression that cannot be described in terms of algebraic expressions. In this question we need to solve for the hydrogen ion concentration:

pH = log (1/[H⁺])

[tex]10^{pH} = \frac{1}{[H^{+}]}[/tex]

[tex][H^{+}] = 10^{-pH}[/tex]

[tex][H^{+}] = 10^{-2.5}[/tex]

[H⁺] ≈ 3.163 × 10⁻³

Answer:

4a) $26.5 because if x represents how many feet then the slope would be the price of one glulam beam.

4b) $63,600

Step-by-step explanation:

To find the answer to 4b we need to alter the equation we were given. Since x represents how many feet we buy we put 2400 in place of x.

y = 26.5 x 2,400

and we simply solve from here

y = 63,600

So, 63,600 is how much we would be spending for 2400 feet of beams. Hope this helps!!

The daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Pete is making decorations for a dinner party. The instructions tell him to use 9 flowers for a medium-sized decoration which has 2 lilies, 1 rose, 3 carnations, 2 daffodils and 1 iris.

The ratio of daffodils to total flower is,

n=2/9.

To make a large decoration, Pete uses 36 flowers. Let suppose the daffodils flower he needs for this is x. Thus,

x=36*(2/9)

x=4*2

x=8

The rose flower is increased from 1 to 2. Thus, the total number of flower also be twice for decoration.

Flower=2*9

Flower=18

Now Pete uses 10 lilies instead of 2 which is 5 times the medium-sized decoration. Thus, the carnations to be needed is,

Carnations=3*5

Carnations=15

Hence, the daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.

Using proportions, it is found that the average waste produced by each plant on a monthly basis is of 0.8 tons per month.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, there is a period of 60 x 12 = 720 months, with 104 plants, and 60,000 tons of waste were produced, hence the average is given by:

A = 60000/(720 x 104) = 0.8 tons per month.

Answer:

Step-by-step explanation:

We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...

 x + 7 = 2x - 30 . . . . eliminate parentheses

 37 = x  . . . . . . . . . . .add 30-x

Answer: Choice G   [tex]\left| \frac{p-n}{n} \right|[/tex]

============================================================

Explanation:

Pick a positive number for p, and a negative value for n. Make sure that p is further away from 0 than n is (so that [tex]|p| > |n|[/tex] is a true statement).

I'll go for these values

Replace every copy of p with 5, and replace every copy of n with -2. Then evaluate or simplify. Use your calculator if needed.

Let's start with choice F.

[tex]F = \left| \frac{p-n}{p} \right|\\\\F = \left| \frac{5-(-2)}{5} \right|\\\\F = \left| \frac{5+2}{5} \right|\\\\F = \left| \frac{7}{5} \right|\\\\F = \left| 1.4 \right|\\\\F = 1.4\\\\[/tex]

Now onto choice G

[tex]G = \left| \frac{p-n}{n} \right|\\\\G = \left| \frac{5-(-2)}{-2} \right|\\\\G = \left| \frac{5+2}{-2} \right|\\\\G = \left| \frac{7}{-2} \right|\\\\G = \left| -3.5 \right|\\\\G = 3.5\\\\[/tex]

Next up is evaluating the expression for choice H.

[tex]H = \left| \frac{p+n}{p-n} \right|\\\\H = \left| \frac{5+(-2)}{5-(-2)} \right|\\\\H = \left| \frac{5-2}{5+2} \right|\\\\H = \left| \frac{3}{7} \right|\\\\H \approx \left| 0.4286\right|\\\\H \approx 0.4286\\\\[/tex]

Then let's compute expression J.

[tex]J = \left| \frac{p+n}{p} \right|\\\\J = \left| \frac{5+(-2)}{5} \right|\\\\J = \left| \frac{5-2}{5} \right|\\\\J = \left| \frac{3}{5} \right|\\\\J = \left| 0.6 \right|\\\\J = 0.6\\\\[/tex]

Lastly, compute expression K.

[tex]K = \left| \frac{p+n}{n} \right|\\\\K = \left| \frac{5+(-2)}{-2} \right|\\\\K = \left| \frac{5-2}{-2} \right|\\\\K = \left| \frac{3}{-2} \right|\\\\K = \left| -1.5 \right|\\\\K = 1.5\\\\[/tex]

-----------------------------------

To summarize, when plugging p = 5 and n = -2 into each expression, we got these results:

Expression G leads to the largest output.

Therefore, [tex]\left| \frac{p-n}{n} \right|[/tex] has the largest value when p > 0 and n < 0.

The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, p is a positive number, n is a negative number, and |p| > |n|.

Let us consider p=5 and n=-2

Now,

F) |(p-n)/p|

= |(5-(-2))/5|

= |7/5|

= 1.4

G) |(p-n)/n|

= |(5-(-2))/(-2)|

= |7/(-2)|

= 3.5

H) |(p+n)/(p-n)|

= |(5-2)/(5-(-2))|

= |3/7|

= 0.43

J) |(p+n)/p|

= |(5-2)/5|

= |3/5|

= 0.6

K) |(p+n)/n|

= |(5-2)/2|

= |3/2|

= 1.5

The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.

Answer:

Step-by-step explanation:

when x = 0, y = 40

therefore you can pick either A or D only.

while x increases, y decreases, that's negative relation

so, answer is D

Answer:

Option D

Step-by-step explanation:

y = mx + b

b is the y - intercept (when x = 0):

this graph doesn't show any negative values on the axis so options B and C can't be true since it they have - 40 when its positive 40

y = mx + 40

The dot association is going downwards, the y values are getting smaller

making this a negative association leaving on ly option d true

[tex]~~~~~~5(x+4) = 40\\\\\implies x +4 = \dfrac{40} 5\\\\\implies x +4 = 8\\\\\implies x= 8-4\\\\\implies x = 4[/tex]
