Why do visit the zoo on cold days￼

**Answer:**

How is this math?

**Step-by-step explanation:**

**Answer:**

Visiting the zoo on cold days limits the number of people there and it isn't too hot so you don't stand in the sweltering heat. Besides, on cold days, the animals may be in a better mood, but be cautioned, remember to bring a jacket just in case.

**Step-by-step explanation:**

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).

[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

NB:

This number is rounded up from -1.72427.....

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

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

**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

D. 714,000 hits

Considering **exponential functions**, it is found that:

**6. **

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

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:

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

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:

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.

**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.

begins with a population of P=340 of this bacteria and there is no change in the growth rate, how

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.

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

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)
