the point (8,3) and is perpendicular to the line 4x +
2y = 10?

The polynomial 2x^3 - 3x^2 x 5 is known as a cubic polynomial.

A cubic polynomial is a polynomial of degree 3, or a polynomial with the highest power of x being 3. This means that the formula for a cubic polynomial can be written as ax^3 + bx^2 + cx + d, where a, b, c, and d are all constants.

In the example of 2x^3 - 3x^2 x 5, the coefficients are 2, -3, 0, and 5 respectively. To calculate the value of the cubic polynomial, one must substitute a value of x into the equation. For example, if x = 2, then the equation would be 2(2^3) - 3(2^2) x 5, which simplifies to 32 - 24 x 5, or 32 - 120, which equals -88.

Therefore, when x = 2, the polynomial 2x^3 - 3x^2 x 5 equals -88. This can be further verified by graphing the polynomial and observing the point (2, -88).

Using the Pythagorean Theorem we can see that, the sides 9 in, 12 in and 15 in can form a right angle triangle.

In the given question, using the Pythagorean Theorem we have to determine if this is a right triangle.

The given sides are 12 in and 15 in.

A key concept in mathematics is the Pythagorean Theorem, which describes the relationship between the sides of a right-angled triangle.

To check the given sides form a right triangle or not. We have to check that the sum of the square of the sides given a proper square root.

We can also check using the triplet. As we know that 3, 4 and 5 is the triplet that can form a right angle triangle.

The multiple of these triplet also can from a right angle triangle.

So a right angle triangle can be formed by 9 in, 12 in and 15 in.

Using the Pythagorean theorem;

[tex]15^2 = 9^2+12^2[/tex]

225 = 81 + 144

225 = 225

Applying the triangle proportionality theorem, the length of AD that will make DE║AB is: AD = 60.

According to the triangle proportionality theorem, the equation or proportion we can create to find x is expressed as:

(2x - 4) / 5x = 3x / 8x

Cross multiply:

8x(2x - 4) = (3x)(5x)

16x² - 32x = 15x²

x² - 32x = 0

Solve to find x by factoring:

The equation x² - 32x = 0 can be solved by factoring:

x(x - 32) = 0

So either x = 0 or x - 32 = 0, meaning x = 32.

The solutions to the equation are x = 0 and x = 32.

Using x = 32:

AD = 2x - 4 = 2(32) - 4

Step-by-step explanation:

the temperature of the water is always inversely proportional to the depth x. the larger the depth the lower the temperature.

just the rate of change changes at certain levels.

so, below 900 meters the relation is defined as

T = 4500/x

at 1200 m this means

T = 4500/1200 = 45/12 = 15/4 = 3.75°C

at 2500 m this means

T = 4500/2500 = 45/25 = 9/5 = 1.8°C

the difference in temperature at these 2 levels is

3.75 - 1.8 = 1.95°C
