The simplified value for the function at g(0) and g(2) are 2 and -20 respectively.

To simplify is to make something simpler. Simplifying an equation, fraction, or issue in mathematics entails taking something complex and making it simpler. The issue is made simpler by calculations and problem-solving strategies. We can simplify fractions by removing all common elements from the numerator and denominator and putting the fraction in its simplest/lowest form.

Given a function g(x) = -4x² - 3x + 2

to find the values of g(0)

and g(2)

for g(0)

substitute x = 0 in the equation,

g(x) = -4x² - 3x + 2

g(0) = -4(0)² - 3(0) + 2

g(0) = 2

for g(2), substitute x = 2 in the equation,

g(x) = -4x² - 3x + 2

g(2) = -4(2)² -3(2) + 2

g(2) = -4(4) - 6 + 2

g(2) = -16 - 6 +2

g(2) = -20

To figure out what percentage of the trail mix is chocolate, we add up all the pieces, divide the number of chocolate pieces by the total and multiply by 100. In this case, we find that 35% of the trail mix is chocolate.

In order to figure out the percent of chocolate pieces in Caitlyn's trail mix, we first need to determine the total number of pieces. Caitlyn counts 28 raisins, 28 chocolate pieces, and 24 peanuts, which gives us a total of 80 pieces in the mix. Then, since there are 28 chocolate pieces, we divide 28 (chocolate pieces) by 80 (total pieces). This will give us the decimal representation of the portion of the mix that is chocolate. To convert this into a percentage, we multiply by 100. Hence, the calculation will be (28/80)*100 = 35%. So, 35% of the trail mix is chocolate.

To find out how many groups of riders there will be, we need to divide the total number of people waiting in line (157) by the maximum number of people allowed on the ride at one time (17).

157 people / 17 people/group = 9.235 groups (approx)

But since the groups must be in whole numbers, we have to round up the value 9.235 groups to the next whole number, which is 10 groups.

So, the number of groups of riders will be 10.

Answer: 9 groups of riders.

Step-by-step explanation:

To find out how many groups of riders there will be, you need to divide the total number of people waiting in line by the maximum number of people allowed on the ride at one time.

157 (total people in line) ÷ 17 (people allowed per ride) = 9.235 (groups of riders)

Because you can't have a fraction of a group, you need to round down to get the whole number of groups.

So the answer is 9 groups of riders.

The boat and the whale are about 218.5 miles apart.

Using the Pythagorean theorem to calculate the distance between the boat and the whale.

Let's call the distance between the boat and the whale "d" and the time they moved apart "t".

1st movement:

d = 45t

2nd movement:

d = (45t + 25(t+35))²

To calculate the final distance, we need to square d from the second movement and add the result from the first movement.

d² = (45t)² + (25(t+35))²

We know that the boat and the whale were moving apart for 35 minutes and 25 minutes, so we can substitute t = 35 and t = 25 in the equation.

d² = (4535)² + (2560)²

Taking the square root of the result and get the final distance between the boat and the whale.

d =  ([tex]\sqrt{4535 ^{2} +2560^{2} }[/tex])

d ≈ 218.5 miles

Hence, the boat and the whale are about 218.5 miles apart.

Answer:

Step-by-step explanation:

?

The car must travel a distance of 130.7 meters. This can be determined by using the equation for distance travelled with a constant acceleration:

Distance = Initial Velocity x Time + (1/2) x Acceleration x Time^2

In this case, the initial velocity is 18.1m/s, the acceleration is 3.7m/s^2, and the final velocity is 29.7m/s. We can set the final velocity equal to the initial velocity and solve for time:

29.7m/s = 18.1m/s + 3.7m/s^2 x Time

Time = 5.4 seconds

We can then plug this value for time into the equation for distance:

Distance = 18.1m/s x 5.4s + (1/2) x 3.7m/s^2 x 5.4s^2

Distance = 130.7 meters

Answer: a. The sum of two numbers is always greater than zero.

Step-by-step explanation:

A counterexample to this conjecture would be when the two numbers are both negative. For example, the sum of -5 and -3 is -8, which is less than zero.

b. The sum of a positive number and a negative number is always positive.

A counterexample to this conjecture would be when the negative number is greater than the positive number. For example, the sum of 5 and -6 is -1, which is less than zero.

c. If a figure has four sides, then it is a rectangle.

A counterexample to this conjecture would be a square. A square has four sides, but it is not a rectangle because all of its angles are 90 degrees while a rectangle has four right angles.

It's good to keep in mind that a conjecture is a statement that is made based on observations and that it hasn't been proven yet, therefore a counterexample can be used to show that the conjecture is false.

Answer:

a)  -5 + 1 = -4

b)  2 + (-10) = -8

c)  A scalene trapezium.

Step-by-step explanation:

A counterexample is proof that a conjecture is false.

Given conjecture:

If one of the numbers is negative, and its absolute value is equal to or greater than the value of the positive number, the result will always be equal to or less than zero.

Counterexample:

As -4 is less than zero, this proves that the conjecture is false.

Given conjecture:

If the absolute value of the negative number is greater than the value of the positive number, the result will always be negative.

Counterexample:

As -8 is negative, this proves that the conjecture is false.

Given conjecture:

Counterexample:

The interior angles of a rectangle are congruent (90°).

A scalene trapezium has four sides, but as its interior angles are all different, it is not a rectangle.  This proves that the conjecture is false.

The year-end balance interest rate for a principal of $100.00 is $105.00, for a principal of $550.00 is $561.00, for a principal of $1,200.00 is $1,284.00.

Interest is the cost of borrowing money or the amount of money that is earned on an investment. It is the amount of money paid by a borrower to a lender or earned by an investment, in exchange for the use of the lender's or investor's money.

Here,

To calculate the year-end balance for each principal using the given annual interest rates, we can use the formula:

End of year balance = Principal + (Principal x Interest rate x Number of years)

For a principal of $100.00, the annual interest rate is 5%, and the number of years is 1. So, the end-of-year balance is:

End of year balance = $100.00 + ($100.00 x 0.05 x 1) = $100.00 + $5.00 = $105.00

For a principal of $550.00, the annual interest rate is 2%, and the number of years is 1. So, the end-of-year balance is:

End of year balance = $550.00 + ($550.00 x 0.02 x 1) = $550.00 + $11.00 = $561.00

For a principal of $1,200.00, the annual interest rate is 7%, and the number of years is 1. So, the end-of-year balance is:

End of year balance = $1,200.00 + ($1,200.00 x 0.07 x 1) = $1,200.00 + $84.00 = $1,284.00

For a principal of $5,000.00, the annual interest rate is 11%, and the number of years is 1. So, the end-of-year balance is:

End of year balance = $5,000.00 + ($5,000.00 x 0.11 x 1) = $5,000.00 + $550.00 = $5,550.00

Hence, the year-end balance for a principal of $100.00 is $105.00, for a principal of $550.00 is $561.00, for a principal of $1,200.00 is $1,284.00, and for a principal of $5,000.00 is $5,550.00

Answer: B. Exponential decay

Step-by-step explanation:

An exponential function is a function of the form f(x) = ab^x where a and b are constants, x is the independent variable, and b is a positive number not equal to 1. In this case, f(x) = -3(4^x). The base of the exponential function is 4, and it is a common base of exponential decay, because the base is less than 1, and the exponent is positive, this means that the output of the function will decrease as the input increases. Therefore, the function represented by f(x) = -3(4^x) is an exponential decay function.

Answer:

Exponential Decay

Step-by-step explanation:

In mathematics, exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed

Substitute the given value into the function and evaluate.

The odds in favor of Amanda unlocking the treasure chest is 1/5.

We have to find the odds in favor of Amanda's character unlocking the treasure chest. Odds in favor is the ratio of the number of favorable outcomes to the number of unfavorable outcomes.

[tex]P (A) = \frac{no.of favorable outcomes}{no. of unfavorable oucomes}[/tex]

P(A), is used to denote the probability of the event A.

Before finding out the odds in favor, we need to find the probability of her unlocking the treasure chest {P(T)}

Total no. of outcomes = 6   (as a dice has 6 sides)

Number of outcomes desired = 1 (that unlocks the treasure chest)

Therefore, the probability of unlocking the treasure chest

P(T) = Number of outcomes desired/ Total no. of outcomes = 1/6

P(T) is our favorable outcome.

Any other outcome would be unfavorable,

Therefore, the number of unfavorable outcomes would be

= Total no. of outcomes - number of the desired outcomes = 6-1 = 5

Thus, applying the formula for P(A)

P(A) = no. of favorable outcomes/ no. of unfavorable outcomes

= 1 / 5 (Ans)

Thus, the odds in favor of Amanda unlocking the treasure chest is 1/5.

Answer:

The total amount in your bank account per year is not a linear relationship, it's compound interest.

Step-by-step explanation:

The total amount in your bank account per year is not a linear relationship because it is not a straight line. Linear relationships are defined by an equation in the form of y = mx + b, where m is the slope of the line, x is the independent variable and y is the dependent variable, and b is the y-intercept.

In this case, the total amount in your bank account per year is not a straight line, it is a curve. The total amount in your bank account will increase as a function of time, but the rate of increase is not constant as it is with linear relationships.

The amount of money in your account will increase over time as the interest is compounded. The interest is calculated on the principal + accumulated interest, so the growth rate of the account is not constant, it increases as the balance grows.

For example, the first year you will earn $5000.03 = $15 in interest, and the second year you will earn $5150.03 = $15.45 in interest, the next year the interest will be $530.45*0.03 = $15.91 and so on.
