The function x² - 3x + 1 represents a quadratic function.
A quadratic function is a function of the form f(x) = ax² + bx + c, where a, b, and c are constants.
In option A, we have f(x) = x² - 3x + 1, which fits the form of a quadratic function with coefficients a = 1, b = -3, and c = 1.
In option B, the function is Exponential.
In option C, the function is Exponential.

A candle on Pauline’s dresser is 4 inches tall and burns at a rate of 0.6 inches per hour. How many hours will it take for the candle to burn down to a height of 1.3 inches?
Answers
The time taken for the candle to burn down to a height of 1.3 inches is 4.5 hours
What is a Linear Function ?A linear function is what can be written in the form of
y =mx+c
The rate at which the candle is burning is 0.6 inches/ hour
The initial height is 4 inches at t=0
The straight line equation can be written for this as
y =mx +c
as m = -0.6
at x = 0 , y = 4 therefore c =4
y = -0.6x +4
The time at which y = 1.3 inches is
1.3 = -0.6x +4
-2.7 = -0.6 x
x =4.5
4.5 hours is the time taken for the candle to burn down to a height of 1.3 inches.

What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The question is: Consider the function f(x) = (-2/3)x - 24 Which conclusions can be drawn about f⁻¹(x) Select two options:
f⁻¹(x) has a slope of -2/3
f⁻¹(x) has a restricted domain.
f⁻¹(x) has a y-intercept of (0, –36).
f⁻¹(x) has an x-intercept of (–36, 0).
f⁻¹(x) has a range of all real numbers.
f(x) = (-2/3)x - 24
To find the inverse of a function:
interchange the x and y
x = (-2/3)y - 24
y = (-3/2)(x + 24)
y = (-3/2)x - 36
The slope of a function f⁻¹(x) is -3/2
From the graph, we can see the y-intercept is (0, -36) and the range will be all real numbers.
Thus, the statement f⁻¹(x) has a y-intercept of (0, –36) and f⁻¹(x) has a range of all real numbers options third and fifth are correct.

What is the slope of a straight line?A slope tells how vertical a line is.
The more the slope is, the more the line is vertical. When the slope is zero, the line is horizontal.
To find the slope, we take the ratio of how much the line's height increases as we go forward or backward on the horizontal axis.
This is because the more the height of the line to the amount we walk or run on the horizontal axis, the more the slope is.

By assuming that the motion of the plastic disc thrown by Mary is a projectile motion, the missing values are 4 and 3 respectively.
How to determine the missing height?Since we're assuming that the motion of the plastic disc thrown by Mary is a projectile motion, it simply means that the motion can be represented by a quadratic function (parabolic).
For a projectile motion, the height of the disc at the time when it's at the top would be the same (equal). Thus, we can logically deduce that:
Height at time (t = 1 seconds) = Height at time (t = 5 seconds)
4 = A.
Similarly, Height at time (t = 0 seconds) = Height at time (t = 6 seconds)
3 = B.

The value of x is 7 and the measure of ∠1 is 99
How to solve for x?The given parameters are:
∠NMQ = 5x + 19∠MQN = 8x - 11∠QNM = 11x + 4The sum of angles in a triangle is 180.
So, we have:
5x + 19 + 8x - 11 + 11x + 4 = 180
Evaluate the like terms
24x = 168
Divide both sides by 24
x = 7
Hence, the value of x is 7
How to determine the measure of ∠1?The angles on a straight line add up to 180.
This means that:
∠1 + ∠QNM = 180
Subtract ∠QNM from both sides
∠1 = 180 - ∠QNM
Substitute ∠QNM = 11x + 4
∠1 = 180 - 11x - 4
Substitute x = 7
∠1 = 180 - 11 * 7- 4
Evaluate
∠1 = 99
Hence, the measure of ∠1 is 99

the spec sheet for the actual 1968 corvette shows the front frame dimension to be 32.875 inches. what would this measurement be, in both fractional and decimal form, on the hot wheels 1:64 model? which form of the measurement would be easier to work with?
Answers
Answer:
0.513671875 = 263/512 inches
easier to use: depends on the measurement tool
Step-by-step explanation:
The model dimension is found by multiplying the actual dimension by the scale factor.
__
model dimensionmodel frame dimension = actual frame dimension × 1/64
= (32.875 inches)/64 = 0.513671875 inches
In fractional form, this is ...
(32 7/8) / 64 = (263/8) / 64 = 263/512 . . . inches
__
ease of useIt is unlikely that a casual hobbyist will have access to tools that measure with a resolution finer than 0.0001 inches. More common would be a measurement resolution of 0.001 inches. Using such tools, the rounded decimal value 0.5137 or 0.514 inches would be more useful than the fractional measurement.
It is possible that an optical measuring device could be available that would present its result as a fraction of an inch. If such a tool were used, the fractional measurement value would provide an appropriate point of comparison.
In short, the measurement easiest to work with depends on the tool being used to make the measurement.

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. The time for which the person must leave the money in the bank until it reaches $2500 is 1.2.
What is compound interest?Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.,
[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]
where A is the final amount
P is the principal amount
r is the rate of interest
n is the number of times interest is charged in a year
t is the number of years
The principal amount is 1000 dollars, while the rate of interest is 6.75% which is compounded monthly. Therefore, the time it will need for the account to reach $2500 is,
2500 = 1000[1+(0.0675/12)¹²ˣⁿ
2.5 = (1.0675)¹²ⁿ
log(2.5)\ log(1.0675) = 12n
14.0278 = 12n
