Sketch the graph of the function f(x, y) x2
The graph of the function f(x, y) = [tex]x^2[/tex] is a three-dimensional parabolic surface that opens upwards.
It is symmetric around the x-axis. This means that the shape of the surface is the same on both the positive and negative x-values. It is also a concave-up function, which means the graph is curved upwards.
Its vertex is located at the origin (0,0) and the equation of the parabola is y =[tex]x^2[/tex]. This means that the x-values of the graph can be any real number, while the y-values will always be non-negative as the square of any real number is always non-negative.
As x-values increase or decrease, the y-values will also increase, resulting in a smooth and continuous surface. Overall, the graph represents the upward parabolic shape of x squared.

Given the function f'(x)=x^{5}-5x^{3}, determine all intervals on which f is decreasing.
The function f'(x) is decreasing on the interval (-√5, 0) and (0, √5)
What is a function?A function is a mathematical equation that shows the relationship between two variables.
How to find the interval on which the function is increasing?Givenj the function f'(x) = x⁵ - 5x³, to find the points at which the function is increasing, we find its critical points by equating it to zero.
So, f'(x) = x⁵ - 5x³
x⁵ - 5x³ = 0
x³(x² - 5) = 0
⇒ x³ = 0 and x² - 5 = 0
⇒ x = 0 and x² = 5
⇒ x = 0 and x = ±√5
To determine the points at which f'(x) is decreasing, we differentiate f'(x) with respect to x and substitute the values of x into it.
So, we have
f'(x) = x⁵ - 5x³
df'(x)/dx = d(x⁵ - 5x³)/dx
f"(x) = 5x⁴ - 15x²
So, f'(x) is decreasing when f"(x) > 0.
So, substituting x = 0 into the equation, we have that
f"(x) = 5x⁴ - 15x²
f"(x) = 0⁴ - 15(0)²
= 0 - 0
= 0
Since f"(x) = 0. This is a point of inflection
Substituting x = √5 into the equation, we have that
f"(x) = 5x⁴ - 15x²
f"(x) = 5(√5)⁴ - 15(√5)²
= 5 (25) - 15 (5)
= 125 - 75
= 50
Since f"(x) = 50 > 0, f'(x) is decreasing
Substituting x = -√5 into the equation, we have that
f"(x) = 5x⁴ - 15x²
f"(x) = 5(-√5)⁴ - 15(-√5)²
= 5 (25) - 15 (5)
= 125 - 75
= 50
Since f"(x) = 50 > 0, f'(x) is decreasing
So, f'(x) is decreasing on the interval (-√5, 0) and (0, √5)

On solving the provided question we can say that the total interest he pay in 5 year is = $17500.
How much is interest?The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money. The basic interest formula is as follows: Interest is equal to P, R, and T. P is the principal sum (the beginning balance). Interest rate, R (usually per year, expressed as a decimal). T = Number of intervals of time (generally one-year time periods).
Money required to borrow new car is $35,000.
and Rick pay 10% interest per year
so, interest he pay in one year = $35000 x 10% = $3500

One-fifth per cent of the blades produced by a blade manufacturing factory turn out to be defective. The blades are supplied in packets of 10.Use Poisson distribution to calculate the approximate number of packets containing no defective in a consignment of1,00,000 packets.
Probability of defect per blade = 1/500 = 0.002
Poisson distribution :
Pₓ (k) = (x ^k)/k × e⁻ˣ
Where k = The number of defective blades in a packet.
For a packet of 10 blades the mean number of defect x = 0.002 × 10 = 0.02
1.) When k = 0
Pₓ(0) = (0.02⁰ / 0!) × e - 0.02 = 0.980199
The approximate number of packets containing blades with no defective is :
10000 × 0.980199 = 9802
2.) When k = 1
Pₓ(1) = (0.02 / 1!) × e-0.02 = 0.019604
Approximate number containing one defective is :
10000 × 0.019604 = 196
3.) When k = 2
Pₓ(2) = (0.02² / 2!) × e - 0.02 = 0.000196
Approximate number containing 2 defective :
0.000196 × 10000 = 1.9 = 2
4.) When k = 3
Pₓ(3) = (0.02³ / 3!) × e-0.02 = 0.000013
Approximate number containing 3 defective is :
0.000013 × 10000 = 0.13 = 0
Answer:
no defective blades in a consignment of 1,00,000 packets is 99837.
Step-by-step explanation:
we first need to find the mean number of packets containing no defective blades. This mean is equal to the total number of packets (1,00,000) multiplied by the probability of a packet containing no defective blades.
The probability of a blade being defective is given as 0.002 (or 2/1000) or 2/100 or 1/50 or 2%.
Since a packet contains 10 blades. So the probability of a packet containing no defective blades is (1 - 0.002)^10 = 0.999936 or (1-0.02)^10 = 0.99837
So the mean number of packets containing no defective blades is (1,00,000 * 0.99837) = 99837

Paula downloaded 16 songs at a total cost of $32.00. What is the unit rate, in dollars, for the songs?
Answer: Paula spent $2 for each song.
Step-by-step explanation: For this question, we have to find the unit rate that Paula paid per song. As we're already given the amount of songs downloaded and the total cost, all that we really have to do is divide!
Because we want to know the amount of money spent on one song, we divide the amount of money spent by the amount of songs purchased. This gives us 32/16 = 2.
Paula spent $2 (don't forget the units!) for each song. This is out unit rate. Hope this helps!

A 3x + 5
B 2x + 1
C 6x +1
D x + 5
Answer:
A
Step-by-step explanation:
6x² + 7x - 5
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 6 × - 5 = - 30 and sum = + 7
the factors are - 3 and + 10
use these factors to split the x- term
6x² - 3x + 10x - 5 ( factor the first/second and third/fourth terms )
= 3x(2x - 1) + 5(2x - 1) ← factor out (2x - 1) from each term
= (2x - 1)(3x + 5) ← in factored form

What is t equal to 30+6t=11t
If 30+6t=11t then the value of t is: 6
How to solve the given equation?This is a simple algebraic equation. To solve for t, we can start by isolating t on one side of the equation.
The equation is 30 + 6t = 11t
First we can subtract 11t from both sides:
30 + 6t - 11t = 11t - 11t
This gives:
30 - 5t = 0
Next, we can add 5t to both sides:
30 - 5t + 5t = 0 + 5t
This gives:
30 = 5t
Finally, we can divide both sides by 5:
30 / 5 = 5t / 5
This gives:
t = 6
So, t is equal to 6.

PLEASEEEE GIVE BRANLIEST
Step-by-step explanation:
There are multiple ways that a function, g, could satisfy the given domain, range, and values of g(0) and g(-9). One statement that could be true for g is:
g(x) = 2x + 8
This function has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45. It also satisfies the values of g(0) = -2 and g(-9) = 6.
It's important to note that this is only one possible function that satisfies the given information and there are many other functions that could also work such as:
g(x) = 3x -2
g(x) = -2x +10
g(x) = x+5

What is the sum of the exterior angles for each of the parallelogram and the hexagon?
A) 90°
B) The answer depends on the number of sides of the polygon
C) 180°
D) 360°
Very confused, if you could please explain it to me, that would be great!!
The sum of the exterior angles for a parallelogram is 360°.
What is exterior angle?Exterior angles are angles that are formed outside two lines when they intersect. They are located outside the two lines, on the outside of the shape. They can be found by adding the two interior angles together, whose measurements are always equal to 180 degrees. Exterior angles are also supplementary angles, meaning that the sum of their measurements is always equal to 360 degrees.
This is because the four angles on the outside of the parallelogram are all right angles, and the sum of four right angles is 360°.
Similarly, the sum of the exterior angles for a hexagon is also 360°.
This is because the six angles on the outside of the hexagon are all 120° angles, and the sum of six 120° angles is 360°.

The heights of American men aged 18 to 24 are approximately Normally distributed with a mean of 68 inches and a standard deviation of 2.5 inches. About what percentage of the men are over 70.5 inches tall?
a ----2.5
b-----68
c-----16
d----5
e-----32
Answer:
Step-by-step explanation:
To find the percentage of men who are over 70.5 inches tall, we need to use the standard normal distribution table, which gives the proportion of observations that fall within a given range of standard deviation from the mean.
We first need to standardize the height of 70.5 inches by subtracting the mean (68 inches) and dividing by the standard deviation (2.5 inches) to get (70.5 - 68) / 2.5 = 0.8
This tells us that 70.5 inches is 0.8 standard deviations above the mean.
We can then look up the proportion of observations that fall within this range in the standard normal distribution table, which is approximately 0.1587 or 15.87%. So, the answer is (1-0.1587) = 84.13 or 84.13%.
So the answer is 84.13%
