Our function is a parabola, therefore, it has only one critical point which is its vertex. Since the coefficient of the squared term is negative, the vertex is the maximum point.The critical points of a function are given by the zeros of the first derivative. The first derivative of our function is:
[tex]f^{\prime}(x)=-6x-18[/tex]The solutions for the following equation are the critical points of the original function:
[tex]-6x-18=0\implies x=-3[/tex]The maximum point happens at x = - 3.
To find the corresponding value, we just have to evaluate x = - 3 into our function:
[tex]f(-3)=-3(-3)^2-18(-3)-26=1[/tex]The maximum value of the function is 1, and it occurs at x = - 3.
Answer: The function has a maximum value
The function's maximum value is 1
The function's maximum value occurs at x=-3
Step-by-step explanation:
Given equation: [tex]g(x) = -3x^ - 18x - 26[/tex]
We shall use the differentiation method to find the answer.
Differentiating the equation, we get [tex]g'(x) = - 6x - 18[/tex]
equating g'(x) = 0,
[tex]-6x - 18 = 0\\-6x = 18 \\x = -3[/tex]
Hence the minimum/ maximum value of the function lies in x = -3
on equating x>-3, g'(x) is negative
on equating x<-3, g'(x) is positive
this proves that first, the function was increasing and after x = -3, the function started to decrease hence at x=-3, the function g(x) was at its maximum value
The function's maximum value at x=-3 is
[tex]g(x) = -3x^2 - 18x - 26\\g(-3) = -3(-3)^2 - 18(-3) - 26\\g(-3) = -3(9) +54 -26\\g(-3) = 54 - 27 -26\\g(-3) = 1[/tex]
"if i flip a coin, i have a 50 percent chance that it will land on heads." in this statement, even after the first coin flip, we still have a 50 percent chance that the next flip will result in a head. this statements interprets "probability" as:
The probability of getting heads on both occasions will be 0.25.
How to calculate the probability?It should be noted that probability simply means the likelihood that a particular event will happen.
In this case, if I flip a coin, i have a 50 percent chance that it will land on heads and after the first coin flip, we still have a 50 percent chance that the next flip will result in a head.
The probability will be:
= P(head) × P(head)
= 50% × 50%
= 1/2 × 1/2
= 1/4
= 0.25

the number of people arriving for treatment at an emergency room can be modeled by a poisson process with a rate parameter of five per hour. what is the probability that exactly four arrivals occur during a particular ""half an hour""?
There is a 0.087 = 8.73% chance that four arrivals will occur at the same half-hour.
What is defined as the Poisson's distribution?The Poisson is a discrete distribution that calculates the likelihood of a given number of events occurring in a given time period.The probability that X is the number of successes of a random variable in a Poisson distribution is given by the following formula: P(X = x) = (e∧(-μ)× μˣ) / x!In which case,
x represents the number of successes.
The Euler number is e = 2.71828 = 2.72
μ is the average over the given time interval.
With a rate parameter of five per hour, the Poisson process is used.
So, μ = 5
The likelihood of exactly four arrivals occurring at the same time;
This is known as P(X = 4).
Put the values in the formula;
P(X = x) = (e∧(-μ)× μˣ) / x!
P(X = 4) = (2.72∧(-5)× 5⁴) / 4!
Simplifying the equation;
P(X = 4) = 0.08736
P(X = 4) = 8.73%
0.087 = 8.73% chance that exactly four arrivals happen during a specific half -hour.

29 less than -10 times a number is equal to -18 times the number plus 91
Answer:
-10x - 29 = -18x + 91
x = 15
Step-by-step explanation:
29 less than -10 times a number is equal to -18 times the number plus 91:
-10x - 29 = -18x + 91
add 21 to both sides:
-10x - 29 + 29 = -18x + 91 + 29
-10x = -18x + 120
add 18x to both sides:
-10x + 18x = -18x + 120 + 18x
8x = 120
divide both sides by 8:
8x/8 = 120/8

one side of rectangle is 5cm than the other side. its perimeter is 38 cm. find the measure of the sides
The measure of the sides of rectangle is 14cm.
What is rectangle?Each pair of neighboring sides in a rectangle are perpendicular, making it a special case of a parallelogram. A parallelogram is a specific type of trapezium, also referred to as a trapezoid in North America, in which the lengths of the two pairs of opposite sides are parallel. A quadrilateral with four right angles is a rectangle. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equal sides.
Given that,
One side of rectangle is 5cm than the other side.
Its perimeter is 38 cm.
P = 2b +2 h
38= 2b+ 2(5)
38= 2b+ 10
38-10= 2b
28= 2b
b = 28/2
b= 14cm.
Therefore, the measure of the sides is 14cm.

Kylie just accepted a job at a new company where she will make an annual salary of $67000. kylie was told that for each year she stays with the company, she will be given a salary raise of $3000. how much would kylie make as a salary after 3 years working for the company? what would be her salary after tt years?
Since the situation can be since as an arithmetic sequence, her salary after 3 years is $73,000. After t years, her salary is a function of t, that is a(t) = 64000 + 3000 t
The given situation can be seen as an arithmetic sequence. The nth term of an arithmetic sequence is given by the formula:
a(n) = a(1) + (n - 1) . d
Where:
a(1) = the first term
d = the common difference.
The problem can be translated into an arithmetic sequence with:
a(1) = $67000
d = $3000
Kylie's salary after 3 years is a(3),
a(3) = a(1) + (3 - 1) . d
a(3) = Kylie's salary + 2 . 3000 = 73000
Hence, after 3 years, Kylie's salary is $73,000
Her salary after t years, means n = t. Therefore,
a(t) = a(1) + (t - 1) . d
a(t) = 67000 + (t -1) . 3000
a(t) = 64000 + 3000 t

The speed limit on a road is listed at 65 miles per hour. The car’s speedometer reads 63 miles per hour. Is it possible that this car is going over the speed limit?
It is not possible for the car to go over the speed limit as maximum error represent value of speed limit less than 65 miles per hour.
As given in the question,
Maximum error on the reading of speedometer =1.6%
Speed limit on a road is 65 miles per hour
Reading of a speedometer = 63 miles per hour
As per the error in the speedometer it can be more or less by 1.6%
To check speed limit
If it more
Speed limit = 63 + (1.6% of 63)
= 63 + 1.008
= 64.008 miles per hour < 65 miles per hour
If it less
Speed limit = 63 - (1.6% of 63)
= 63 -1.008
= 61.992 miles per hour < 65 miles per hour
Therefore, it is not possible for the car to go over the speed limit as maximum error represent value of speed limit less than 65 miles per hour.

The total cups of flour Alice, Raul and Jane have altogether is equal to 6.
We can determine the number of cups of flour they have all together by the addition of the fractions brought by each one of them.
First, we convert the decimal value of 2.5 into fraction form;
2.5 = 2.5/1
Multiplying and dividing both sides by 10;
25/10 = 5/2
Now we add the fractions as follows;
Total number of cups of flour = 5/2 + 11/4 + 3/4
We Multiply 5/2 by 2 to get the same denominator as the other values;
5×2 / 2×2 = 10/4
10/4 + 11/4 + 3/4 = 6
Therefore, the total number of cups of flour they have altogether is calculated to be 6.
