How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
f(x) = 3x² - 2x + 5.
At x = -5, the numeric value is obtained replacing the two instances of x by -5, hence:
f(-5) = 3(-5)² - 2(-5) + 5 = 90.

What alternate for of genes do nucleic acids have that allows them to offer variability?
Nucleic acids offer variability through their ability to undergo mutations.
What is mutation?Mutation is a process in which a gene or organism undergoes a change in its DNA sequence, resulting in a new trait or altered function. Mutations can occur naturally or be induced by environmental factors such as radiation, chemicals, or viruses. Mutations can be beneficial, harmful, or have no effect on the organism. Some mutations can cause genetic disorders or even cancer.
Mutations are changes in the sequence of nucleotides that make up a gene, resulting in a different form of the gene. These mutations can lead to different traits in the organism, providing a greater range of variability in the gene pool. Mutations can be caused by environmental factors such as radiation or chemicals, as well as random changes that occur as DNA is replicated. The range of variability offered by mutations is one of the main reasons why organisms are able to adapt to their environment.

Gerardo changed a $100 at the bank. He received $20 bills and $10 bills.
$20 bills was 2 more than the number of $10 bills. How many bills of each kind did he
receive?
Write using LESCA
Answer:
• Two $10 bills
• Four $20 bills
Step-by-step explanation:
We are told that Gerardo received a number of $20 and $10 bills upon changing a $100 bill at the bank. We are also told that he received 2 more $20 bills than $10. Then we are asked to find the number of each kind of bill.
To solve this problem, let's consider the number of $10 bills he received was [tex]x[/tex]. Since he received 2 more $20 bills, he got [tex](2 + x)[/tex] $20 bills. Therefore, in total he received:
[tex]10 \times x + 20 \times (x +2)[/tex]
This should add up to $100 since that is the amount he changed. Solving the resulting equation for [tex]x[/tex] will give us the number of $10 bills he received.
[tex]10 \times x + 20 \times (x +2) = 100[/tex]
⇒ [tex]10x + 20x + 40 = 100[/tex]
⇒ [tex]30x +40 = 100[/tex]
⇒ [tex]30x + 40 - 40 = 100 - 40[/tex] [Subtracting 40 from both sides of equation]
⇒ [tex]30x = 60[/tex]
⇒ [tex]\frac{30}{30}x = \frac{60}{30}[/tex] [Dividing both sides of the equation by 30]
⇒ [tex]x = \bf 2[/tex]
Therefore, he received 2 $10 bills.
Since the number of $20 bills is 2 more than the number of $10 bills,
no. of $20 bills = 2 + 2
= 4

How can you solve two-step inequalities?
Explain shortly.
To solve a two-step inequality, you can follow these steps:
Isolate the variable on one side of the inequality by performing the same operation on both sides of the inequality.
If the inequality is a "greater than" or "less than" inequality, you will need to reverse the inequality if you multiply or divide by a negative number.
Solve the inequality by isolating the variable.
Check your solution by plugging it back into the inequality and making sure it is true.
Graph the solution in number line
Example:
x + 2 > 6
x > 4
(x+2) > 6
x > 4 (by isolating x)
It is important to remember that if we multiply or divide by a negative number, we have to reverse the inequality sign.
It is also important to remember that after solving the inequality, it is necessary to check the solution by substituting it back into the original inequality to make sure it works.

The difference in the account balance after 30 years if the electrician's investment was compounded continuously instead of twice per year would be $83.63.
What is value?Value is the worth of something that is measured in terms of its quality, importance, and usefulness. It is a fundamental concept in economics, finance, and business, as it reflects the perceived benefits of a good or service compared to its cost. Value can be subjective, as it is often based on personal opinion or preference. It can also be quantified and measured in terms of money, time, or resources.
Compound interest is the concept of earning interest on the initial principal and any interest previously earned. When the interest is compounded continuously, the interest is added to the principal more frequently than when it is compounded semiannually, resulting in a larger final balance.
The electrician's initial investment of $9,000 compounded semiannually at 2.45% for 30 years would have a balance of $18,685.71.
However, if the same investment had been compounded continuously at 2.45%, the balance after 30 years would be $18,769.34, which is $83.63 more than the semiannually compounded balance.

Mark bought a new car. The total amount he needs to borrow is $28,716. He plans on taking out a 4-year loan at an APR of 3.12%. What is the monthly payment?
The monthly payment with given simple interest will be $673.
What is simple interest?
Simple Interest is an easy method of calculating the interest for a loan/principal amount. Simple interest is a concept that is used in many sectors such as banking, finance, automobile, and so on. When you make a payment for a loan, first it goes to the monthly interest and the remaining goes towards the principal amount.
Simple interest formula is given as:
SI=P*R*T/100
Where SI = simple interest
P = principal
R = interest rate (in percentage)
T = time duration (in years)
In order to calculate the total amount, the following formula is used:
Amount (A) = Principal (P) + Simple Interest (SI)
Now,
Amount to Borrow=$28716
Rate=3.12%
Time=4 years
SI=28716*3.12*4/100
=$3584
Total amount to pay=28716+3584
=$32300
Hence,
monthly payment for 4 years =32300/48

write a cosine function that has a midline of 4, an amplitude or 3 and a period of 7/3
The cosine function will be equal to f(x) = 3cos(π(6/7)x) + 4
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
A generic cosine function is written as:
f(x) = Acos(wx + p) + M
where:
A = amplitude
w = angular frequency
p = phase
M = midline.
We know that:
The midline is 4, then M = 4
The amplitude is 3, then A = 3
There is no information about the phase, so p = 0.
And we know that the period is 7/3.
The period is written as T, and the relation between the period and the angular frequency is:
T = 2π/w
Then we have:
7/3 = 2π/w
w = (2π)*(3/7) = π x (6/7)
where π= 3.14
Then we have:
w = π x (6/7)
A = 3
M = 4
p = 0
Hence, the cosine function is: f(x) = 3cos(π(6/7)x) + 4

How do you tell if a graph is exponential growth or decay?
To tell if a log graph is a growth or decaying, look at the slope of the line. If the slope is positive, then it is growth; if the slope is negative, then it is decay.
A positive slope indicates that the value is increasing over time, while a negative slope indicates that the value is decreasing over time. To find the slope, take two points on the line and calculate the change in the y-value divided by the change in the x-value.
If the answer is positive, the graph is growth; if the answer is negative, the graph is decay. Additionally, you can look at the y-intercept of the graph, which is the value where the line meets the y-axis. If the y-intercept is positive, the graph is growth; if the y-intercept is negative, the graph is decay.
