f(x) = 3x² + 2x - 20 for x = 3
help please?
When we're given f(x) and x, we can evaluate the function by replacing every x with the given value, and simplifying.
Solving the Question[tex]f(x) = 3x^2 + 2x - 20[/tex]
⇒ Replace every x with 3:
[tex]f(3) = 3(3)^2 + 2(3) - 20\\\\f(3) = 3(9) + 6 - 20\\\\f(3) = 27 + 6 - 20\\\\f(3) = 13[/tex]
Answer[tex]f(3) = 13[/tex]
Step-by-step explanation:
A function is a relationship bound to one output for every single input the value of F(3) for the given function F(x)=3x²+2x-20 is 13.
What is a function?
The function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
A certain kind of relationship called a function binds inputs to essentially one output.
As per the given function,
F(x)=3x²+2x-20
Substitute, x = 3
F(3) = 3(3)^2 + 2(3) - 20
F(3) = 3(9) + 6 - 20
F(3) = 13
Hence "A function is a relationship bound to one output for every single input the value of F(3) for the given function F(x)=3x²+2x-20 is 13".

Sandpiper Company has 25,000 shares of cumulative preferred 1% stock, $150 par and 50,000 shares of $5 par common stock. The following amounts were distributed as dividends:
20Y1 $75,000
20Y2 15,000
20Y3 112,500
Determine the dividends per share for preferred and common stock for each year. Round all answers to two decimal places.
If Sandpiper Company has 25,000 shares of cumulative preferred 1% stock.
Dividends per share for preferred
Year 1 = $3 per shareYear 2 = $4.5 per shareYear 3 = $1 per shareCommon stock
Year 1 = $0Year 2 = $1.95Year 3 =$1.75How to find the dividends per share and common stock?The arrear $75,000 of unpaid dividends from year 1 will be paid to preferred stockholders in year 2
= ($150 x 1% x 25,000) +$75,000
= ($37,500 + $75,000)
= $112,500
Year 1 Year 2 Year 3
Distributed $75,000 $15,000 $112,500
Preferred $75,000 $112,500 $25,000
Common $0 $97,500 $87,500
Dividends per share for preferred
Year 1 = $75,000/25,000 shares
Year 1 = $3 per share
Year 2 = $112,500 /25,000 shares
Year 2 = $4.5 per share
Year 3 = $25,000/$25,000 shares
Year 3 = $1 per share
Common stock
Year 1 = 0/ 50,000 shares
Year 1 = $0
Year 2 =$97,500 / 50,000 shares
Year 2 = $1.95
Year 3 = $87,500 /50,000 shares
Year 3 =$1.75
Therefore the dividends per share for preferred is $3 per share, $4.5 per share, $1 per share and the common stock $0, $1.95, $1.75.

a) The dot plot of the data-set is given by the second image shown at the end of the answer.
b - i) The mean of the distribution is of: 1.6 goals.
b - ii) The median of the distribution is of: 1.
b - iii) The mode of the distribution is of: 1 goal.
What are the measures?The mean is given by the sum of all observations of the data-set, hence it is of:
Mean = (0 x 5 + 1 x 6 + 2 x 4 + 3 x 3 + 4 x 1 + 5 x 1)/20 = 1.6.
The median of the distribution is the middle value of the distribution, which is the value of which half the distribution is less than and half is greater than.
Adding in the frequency table given at the end of the answer, it is found that the middle term is of 1, as the sum of the frequencies reaches 10, which is half of the cardinality of 20, at a number of 1.
The mode is the term with the highest absolute frequency, hence it is also of one goal, as it has the highest absolute frequency, which is of 6.
The dot plot gives a dot to each measure for each time that it appears, hence it says the same thing as the table, in a different format.

The company pays one penny on the first day, 2 cents on the second day, 4 cents on the third day, and so on.
This situation represents the geometry sequence below as

Explain why the equation cos(x) = x has at least 1 solution
There exists a point c ∈ [0, 2π], therefore, f(c) =0, Hence cos x = x has at least one solution.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
cos(x) = x (1)
For the given interval [0, 2π],
By intermediate theorem, for c ∈ [0, 2π], for which f(c) =0
Or we can say that, at x = 0, f(0) = 0
Therefore, cos(x) has at least one solution, in the interval [0, 2π]
So, given equation cos(x) = x has one solution.

Find the HCF of 2, 4 and 4/5.
(A) 1/20 (B) 1/40 (C) 20 (D) 15
Answer:
1/20
Step-by-step explanation:
You can find the HCF (Highest Common Factor), also known as GCF, by dividing the numbers by the list of answers. And, if they all come out as whole numbers, then the answer you chose will be the answer. But, if there is another answer that also comes out as whole numbers for all of them, we choose the biggest one (HCF):
2 ÷ 1/20 = 40
4 ÷ 1/20 = 80
4/5 ÷ 1/20 = 16
So, 1/20 is definitely one of the answers, but we should check the other ones too:
2 ÷ 1/40 = 80
4 ÷ 1/40 = 160
4/5 ÷ 1/40 = 32
So, even though we also got whole numbers for this one, it isn't the answer because 1/20 is bigger than 1/40 so far. Let's try the last two answers:
2 ÷ 20 = 0.1
So, we already got our answer. We don't need to check the rest of the numbers, because the first one is already not a whole number. Let's try the final answer:
2 ÷ 15 = 0.13333333
This is not the right one either. So, our answer is 1/20 because it is the biggest one that came out as all whole numbers.

approximately the same, and the data were
collected independently and randomly. Use a
level of significance of 0.05.
By using the concept of mean and standard deviation, it can be inferred that
The the drug stays in the system for more than 397 minutes
What is mean and Standard Deviation?
Suppose there is a data set and the average of the data set has to be calculated. To calculate the average of the data set, mean is used
To know about Standard Deviation, it is important to know about Variance
Variance is the sum of the square of deviation from mean.
Square root of the variance gives the standard deviation
Given n = 35,
Population mean = 397
Population Standard Deviation = 18
Here the sample size is large. So the distribution is approximately normal
To test :
Test statistic t =
= 1.97
p value at = 0.0244
Since 0.0244 < 0.05, the null hypothesis is rejected
So the the drug stays in the system for more than 397 minutes

A ball is thrown from a height of 3 meters with an initial downward velocity of 5 m/s The ball's height h (in meters) after t seconds is given by the following. how long after the ball is thrown does it hit the ground
The ball hits the ground at a time of 1.433 seconds.
How to calculate the time until the ball hits the ground
In this problem we have the case of a ball that experiments a free fall, that is, an uniform accelerated motion due to gravity. The position of the ball in time is described by a quadratic equation:
y = y' + v' · t + 0.5 · g · t²
Where:
y' - Initial position, in meters.v' - Initial speed, in meters per second. t - Time, in seconds. g - Gravitational acceleration, in meters per square second.y - Final position, in meters.If we know that y' = 3 m, v' = 5 m / s, g = - 9.807 m / s², y = 0 m, then the time of the ball until it hits the ground is:
0 = 3 + 5 · t - 4.904 · t²
Then, by the quadratic formula:
t = - v' / g ± (1 / g) · √[v'² - 2 · g · y']
t = - 5 / (- 9.807) ± [1 / (- 9.807)] · [5² - 2 · (- 9.807) · 3]
t₁ = 1.433 s. or t₂ = - 0.424 s.
