If pH = -log [H+], find the pH of a substance that has a hydrogen concentration [H+] = 5.7 X 10-4.Round your answer to the nearest ten thousandth (4 decimals).

Answers

[H+] = -1.7243

Explanation:

Since [H+] = 5.7 * 10 - 4, in the function -log[H+] representing pH, replace H+

pH = -log [5.7 *10 - 4]

pH = -log[53]

pH = -1.7243

express y in terms of x: 6(x-y) = 19

Answers

Expressing y in terms of x gives y = x - 19/ 6

What is subject of formula

Subject of formula can be defined as the variable that is being expressed in terms of other variables in an equation, function or expression.

It is also described as the variable that is being worked out in an expression or equation.

It is made to stand alone on on side of the equality sign.

We have the equation;

6(x-y) = 19

To make 'y' the subject of formula, let's take the following steps;

Divide both sides by 6, we have;

x - y = 19/ 6

now, take the variable 'x' over the equality sign

-y = 19/ 6 - x

Divide both sides by -1

y = x - 19/ 6

Hence, the equation is y = x - 19/ 6

Evan runs a website that has gotten quite popular. However, its popularity seems to be decreasing and the site is now getting 7% fewer hits each week. If Evan's site got 34,000 hits this week, how many weekly hits can he expect it to get 3 weeks from now?

Round to the nearest whole number.
A. 134,360 hits
B. 27,348 hits
C. 41,651 hits

Answers

Considering exponential functions, it is found that:

12. The number of hits 3 weeks from now will be of 27,348, hence option B is correct.

What is an exponential function?

An exponential function is modeled according to the rule given next:

[tex]y = ab^x[/tex]

The parameters of the exponential function are defined as follows:

a is the y-intercept, which is the numeric value of the function when x = 0.b is the rate of change of the function.

For item 6, considering the points (0,10) and (1,7.5), the parameters are given as follows:

y-intercept of 10, which is the starting value.When x = 1, y = 7.5, given the value after one year.

For item 12, the initial amount and the rate of change are given as follows:

a = 34,000, b = 1 - 0.07 = 0.93.

Hence the number of hits x weeks from now is modeled according to the following function:

[tex]h(x) = 34000(0.93)^x[/tex]

After 3 weeks, x = 3, hence the number of hits will be of:

[tex]h(3) = 34000(0.93)^3 = 27348[/tex]

Meaning that option B is correct.

The owner of a frozen yogurt stand considers different pricing options for a serving of yogurt plus toppings. For what number of toppings do the two options give the same price?
A. Define the variables.
B. Write a system of equations that models this situation.
C. Graph the system. What is the intersection point?
D. What is the solution of the problem?
E. Is the solution reasonable for this situation? Explain.

Answers

Answer:

Step-by-step explanation:

A, B:  Define the Variables and Write Equations

Let T be the number of toppings.

Option 1:  $3 + $0.75*T

Option 2:  $4 + $0.50*T

C.  Graph the System

See the attached graph.  The intersection point is (4,6).  This means that 4 toppings will result in a cost of $6 for both yogurt options.

D.  Solution to the Problem

The solution is given above, but we can also solve using equations, instead of graphing.  We want the value of T that will make these expressions equal:

$3 + $0.75*T = $4 + $0.50*T

$0.25*T = $1

T = 4 toppings

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

CHECK:

For 4 toppings:

Option 1:  $3 + $0.75*T

                  $3 + $0.75*(4)

                  $3 + $3 = $6

Option 2:  $4 + $0.50*T

                  $4 + $0.50*(4)

                  $4 + $2 = $6

Four toppings will make both options equal in cost.

E:  Is the solution reasonable?

Yes.  The cheaper option ($3) has a more expensive topping, so at some point (at 4 toppings) it will be the same price as the second option, with a higher initial price, but with cheaper toppings.

The equation of the given linear function passing through two points is

y = 6 -2x.

What is equation of a linear function passing through given two points?

Let (x₁, y₁) and (x₂, y₂) be two points on the given linear function whose equation in variables x and y is given by formula below.

(y -  y₁) = {(y₂ -y₁)/(x₂-x₁)} (x -x₁)

Given that  f is a linear function ,

f(-3) = 12

f(6) = -6

⇒(x₁, y₁) = ( -3,12)

  (x₂, y₂) = ( 6,-6)

Thus the equation of the linear function is :

⇒ y - 12 = { ( -6-12)/(6-(-3))} ( x - (-3))

⇒ y - 12 = { -18/ 9} ( x +3)

⇒ y - 12 = -2 ( x+3)

⇒ y = 12 -2x - 6

⇒ y = 6 -2x

many bacteria will be present in t=37 minutes?
Hint: Use equation P = Poekt, where k is the relative growth. Round to two decimal places.

Answers

The bacteria present at t=37 minutes is found to be 8.40, with no change in growth rate.

What does population growth exponentially mean?

When a population's per capita growth rate remains constant, regardless of population size, exponential growth occurs, causing the population to grow exponentially as the population increases.

Given:

P = 340

It has been discovered that a specific bacterial population doubles in 20 minutes.

k = 2/20 = 0.1

t = 37 minutes

We know that,

P = P₀[tex]e^{kt}[/tex]

340   = P₀([tex]e^{0.1*37}[/tex])

340 =P₀(40.44)

P₀ = 8.40
