The sequence that can be defined by the recursive formula is (c) 4, 2.75, 1.5...
How to determine the elements of the recursive definition of f?The function definition is given as
f(1) = 4
f(n + 1) = f(n) - 1.25 for n ≥ 1
Set n = 1
So, we have the following representation
f(1 + 1) = f(1) - 1.25
This gives
f(2) = f(1) - 1.25
So, we have
f(2) = 4 - 1.25 = 2.75
Set n = 2
So, we have the following representation
f(2 + 1) = f(2) - 1.25
This gives
f(3) = f(2) - 1.25
So, we have
f(3) = 2.75 - 1.25 = 1.5
So, we have
4, 2.75, 1.5...
The sequence that matches 2.75, 1.5... in the options is (c) 4, 2.75, 1.5...
Hence, the sequence is (c) 4, 2.75, 1.5...

The temperature dropped to 24 degrees in 8 days. what was the average daily change in temperature? a) 3 degrees b) -8 degrees c) -3 degrees d) 16 degrees
The average daily change in temperature will be 3 degrees The temperature dropped to 24 degrees in 8 days
Since we know an average could be a single number taken as an agent of a list of numbers, as a rule, the whole of the numbers divided by how numerous numbers are within the list. We are said the temperature dropped to 24 degrees in the 8 days
So the average of it will be =24 /8 = 3, which means the temperature needed to drop for at least 3 degrees in order to get the sum of 28 in 8 days.

Base of an isosceles triangle can be right angles
We can actually deduce here that the statement, "base of an isosceles triangle can be right angles" is false.
What is an isosceles triangle?An isosceles triangle is actually known to be a triangle which has two sides equal and opposite angles of the sides also equal. In other words, an isosceles triangle must have at least two equal triangles.
Some of the properties of an isosceles triangle are:
It is a triangle whose two sides are congruent to each otherIt has a third side known as the base of the isosceles triangle.It has angles that are opposite to the equal sides which are congruent to each other.We see here that the base of an isosceles triangle cannot be a right angles.

The simplification of the number by solving square root 5√18 is 15√2.
What is meant by the term square root?A number's square root is a value that, if multiplied by itself, yields the original number. The other procedure to square an integer is to find its square root. Squares as well as square roots are hence related ideas.Providing that x is just the square root of y, the equation would be written as x=y or as x² = y. The radical symbol for the number's root is "√" in this instance. The square of the positive number is shown by multiplying it by itself. The original number is obtained by taking the square root of a square of such a positive number.For the given number

Determine the function's value when x=-1.
Og(-1)=-3
O g(-1)=0
O g(-1)=1
O g(-1)=27
The function g(-1) has its value to be (c) g(-1) = 1
How to evaluate the function at the input value?The definition of the function is given as
g(x)=x³+6x² + 12x+8
Rewrite the above function properly
So, we have the following representation
g(x) = x³ + 6x² + 12x + 8
To find the function g(-1), we set the value of x in the equation g(x) = x³ + 6x² + 12x + 8 to -1
This is represented by
Calculate g(x), when x = -1
Substitute -1 for x in the equation g(x) = x³ + 6x² + 12x + 8
So, we have the following equation
g(-1) = (-1)³ + 6(-1)² + 12(-1) + 8
Evaluate the exponents
This gives
g(-1) = -1 + 6(1) + 12(-1) + 8
Evaluate the products
This gives
g(-1) = -1 + 6 - 12 + 8
Evaluate the sum
g(-1) = 1

what is 382 3/10 minus 191 87/100
Answer:

Step-by-step explanation:
First, you turn the mixed fractions into improper fractions. 382 3/10 is 3823/10, and 191 87/100 is 19187/100. Then, you need to have a common denominator in order to subtract. This turns 3823/10 into 38230/100. 38230/100 - 9187/100 is 19043/100 since you only subtract the numerators. Finally, you turn it back into a mixed fraction by dividing 19043/100.

In this problem 0.7 is the standard deviation of the contents.
Define standard deviation.It is a statistic that gauges a dataset's dispersion from its mean, and it is calculated as the variance's square root. By calculating the deviation of each data point from the mean, the standard deviation may be determined as the square root of variance. The standard deviation reveals the degree of data skewedness. It gauges how far away from the mean each observed value is. Approximately 95% of values in any distribution will be within two standard deviations of the mean. A dataset's dispersion from its mean is measured by standard deviation. It is determined as the variance's square root. In the financial industry, standard deviation is frequently employed as a gauge of an asset's relative riskiness.

How to graph the system of linear equations on a coordinate plane?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
y=4/3x+4
3y=-2x-6
Rewrite the equations in the system of equations as follows:
So, we have the following representation
y = 4/3x + 4
3y = -2x - 6
Next, we plot the graph of the system of equations
In this case, the point of intersection of the equations represent the solution to the system
From the graph, the lines intersect at (-3, 0)
This means that the solution to the system of equations is (-3, 0)
See attachment for the graph of the system of equations
