Find the equation to represent the volume of
a cylinder with diameter 10 and height of 2x.

The maximum height covered is 32m and the time taken to reach maximum height is 1.25 seconds

A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. rate of change = change in y / change in x. Rates of change can be positive or negative.

h(t) = -16[tex]t^{2}[/tex] +40t + 7

at maximum height the rate of change of h(t) with respect to t is zero.

so [tex]\frac{dh(t)}{dt}[/tex] = 0

but  [tex]\frac{dh(t)}{dt}[/tex] =  -32t + 40

so,

-32t + 40 = 0

32t = 40

t = 40/32

t = 1.25

to find h(t), we substitute t = 1.25 into the equation above

h(t) = -16[tex](1.25)^{2}[/tex] + 40(1.25) + 7

h(t) = 32m

In conclusion, the maximum height reached is 32m and the time taken to reach maximum height is 1.25 seconds

The function g(-1) has its value to be (c) g(-1) =  1

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

Hence, the value of the function is g(-1) =  1

                   [tex]= \frac{350g}{1000g}=\frac{7}{20}g= 0.35g[/tex]

What is fraction?

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.

In a simple fraction, both are integers.

A complex fraction has a fraction in the numerator or denominator.

In a proper fraction, the numerator is less than the denominator.

Explanation of the answer:

Given that :

350g/1kg

Firstly we convert kilogram into gram:

1 kg = 1000 g

The mass m in grams (g) is equal to the mass m in kilograms (kg) times 1000:

m(g) = m(kg) × 1000

Answer:

X=30

Step-by-step explanation:

[tex](4x + 30) + (2x - 30) = 180 \\ 4x + 2x + 30 - 30 = 180 \\ 6x = 180 \\ x = 30[/tex]

Answer:

x = 30

Step-by-step explanation:

We are told that:

• m∠A =  (4x + 30)°

• m∠B = (2x - 30)°,

and that these two angles are supplementary to each other.

When two angles are supplementary to each other, it means that they add up to 180°.

Therefore:

∠A + ∠B = 180°

⇒ (4x + 30)°  +  (2x - 30)° = 180°

⇒ 4x + 30 + 2x - 30 = 180

⇒ 4x + 2x + 30 - 30 = 180      [Combining like terms]

⇒ 6x = 180

⇒ [tex]\frac{6}{6}x = \frac{180}{6}[/tex]     [Dividing both sides of the equation by 6]

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.

Given that on a coordinate plane, line A has a negative slope, line b is horizontal, line c is vertical, and line d has a positive slope.

The line with no slope will be line b because the line is a horizontal line.

Step-by-step explanation:

We need to add 81 as the constant term to the binomial (n² - 18n) so that the resulting trinomial is a perfect square, and factorization of that resulting trinomial will be (n - 9).

As per the question statement, we are provided with a binomial (n² - 18n),

And we are required to add a proper constant to the above mentioned binomial so that the resulting trinomial is a perfect square, and then factorise the resulting trinomial.

To answer question, first we need to know the standard form of expanding a perfect square into a trinomial, which goes as,

[(a - b)² = {(a)² + (b)² - (2 * a * b)]

Here, if we compare our concerned binomial (n² - 18n), or, [(n)² - (2 * n * 9)], with the above mentioned standard expansion of a perfect square into a trinomial, we get, (a = n) and (b = 9), and the (b²) term is missing.

Adding [(b²) = (9²) = 81] which is a constant term, to our concerned binomial (n² - 18n), we get, (n² - 18n + 81),

Or, [(n)² + (9)² + (2 * n * 9)],

Which is a trinomial and matches with the standard expansion of a perfect square into a trinomial, and hence,

[(n² - 18n + 81) = (n - 9)²]

That is, we need to add 81 as the constant term to the binomial (n² - 18n) so that the resulting trinomial is a perfect square, and factorization of that resulting trinomial will be (n - 9).

Step-by-step explanation:

they are parabolas.

their line of symmetry is exactly in the middle between their x-intercepts (when y = 0).

these x-intercepts we get from the factors : y can only be 0, when at least one of the factors is 0.

y = (x + 14)(x + 16)

means y = 0, when x = -14 or x = -16.

so, the line of symmetry is

x = -15

y = (x - 12)(x - 18)

y = 0, when x = 12 or x = 18

line of symmetry is

x = 15

y = (x + 13)(x - 17)

x = -13 or x = 17

x = 2 (again, the middle between -13 and +17)

y = (x - 10)(x + 20)

x = 10 or x = -20
