Explanation:

Given zero's of a polynomial function:

Answer:

y = x² + 5x - 14

Step-by-step explanation:

If the zeros of a polynomial are 2 and -7, then:

⇒ x = 2  ⇒  (x - 2) = 0

⇒ x = -7  ⇒  (x + 7) = 0

Therefore, we can write the polynomial as:

y = a(x - 2)(x + 7)   where a is some constant

As the first term of the given polynomial is x², we can say that its coefficient is 1.  Therefore, a = 1

⇒ y = 1(x - 2)(x + 7)

⇒ y = (x - 2)(x + 7)

To write the polynomial in standard form  ax² + bx + c

simply expand the brackets:

⇒ y = (x - 2)(x + 7)

⇒ y = x² + 7x - 2x - 14

⇒ y = x² + 5x - 14

The path to convert coal into electricity is Boiler to Turbine to Generator to Power lines, the correct option is A.

Those fuels which have originated from decayed plants and animals over a long period of time are called Fossil fuels.

The correct path energy follows when coal or oil is burnt to produce electricity is

When coal is fired the heat is used to convert water into steam in a boiler.

The steam at high pressure is sent to turbines.

The steam spins the generator to produce electricity which is then sent to the power lines.

Therefore, the correct path is mentioned in option A.

The increase in the percentage that they experience over these first two years will be 12.5%. Then the correct option is D.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.

A swim team has 80 swimmers in the first year and 90 swimmers in the second year.

Then the increase in the percentage that they experience over these first two years will be

P = (90 - 80)/80 x 100

P = 10/80 x 100

P = 0.125 x 100

P = 12.5%

Answer:

answer = 90

Step-by-step explanation:

General equation:  a = k*b^2

Specifically:          10 = k*(3)^2 = 9 k

Solving for k:  k = 10/9

Then a = (10/9)b^2.    If b = 9, then a = (10/9)(9)^2 = 90 (answer)

Answer:

There is 166.1 grams of sugar in 5.5 yards of licoroce

Step-by-step explanation:

If 1.5 yards of licorice = 45.3 grams of sugar

5.5 yards of licorice = x

Cross multiply:

45.3grams * 5.5yards / 1.5yards

= 249.15 grams/yards / 1.5yards

= 166.1 grams of sugar

For the first question

[tex]x = 2 \: cm[/tex]

For the second question

[tex]x = 6 \: cm[/tex]

Step-by-step explanation:

To find the value if x in both equation we have to use the Pythagorean Theorem which states that:

[tex] {a}^{2} = {b}^{2} + {c}^{2} [/tex]

a being the hypothenus*

Therefore for the first question we know that

[tex]a = x \: \: \: b = 1.6 \: \: \: \: c = 1.2 \\ so ... \: \: {x}^{2} = {1.6}^{2} + {1.2}^{2} \\ {x}^{2} = 2.56 + 1.44 \\ {x}^{2} = 4 \\ \sqrt{ {x}^{2} } = \sqrt{4} \\ x = 2 [/tex]

For the second question we know that

[tex]a = 6.5 \: \: \: b = 2.5 \: \: \: c = x \\ {6.5}^{2} = {2.5}^{2} + {x}^{2} \\ 42.25 = 6.25 + {x}^{2} \\ 42.25 - 6.25 = {x}^{2} \\ 36 = {x}^{2} \\ \sqrt{36} = \sqrt{ {x}^{2} } \\ 6 = x[/tex]

Answer:

Below in bold.

Step-by-step explanation:

f(x)=2x^3-3x^2

Finding the derivative and equating to zero:

f'(x) = 6x^2 - 6x = 0

6x(x - 1) = 0

So there are turning point at x = 0 and 2 = 1.

Finding the relative maximum:

Second derivative is negative when we have a maximum value:

f"(x) = 12x - 5

- which is negative when  x = 0.

So the relative maximum is at x = 0 where f(x) = 2(0)^3 - 3(0)^2 = 0.

At x = 1, second derivative  = 12(1) - 5 = +7 so this is a relative  minimum.

The function is increasing  in interval -∝ < x < 0

decreasing in interval 0 < x < 1

then increasing in interval   1 < x < ∝

Answer:

The percentage change in volume between cylinder A and cylinder B is 50% Step-by-step explanation:

Step-by-step explanation:

The volume of a cylinder is given by the formula

V= πr^2h

For cylinder A, where r = 7 and h = 5 , pi = 22/7

V= π *7^2 * 5

V= π * 49 * 5

V = 769.69 cubic inch

For cylinder B

V = 490Pi

V = 153 cubic inch

The percentage change in volume between cylinder A and cylinder B

=[ (VA-VB)/VB] *100

=(1539.3804-769.69)/1539.3804

= 0.5000 100

Answer:

x=0; x=-2

Step-by-step explanation:

so first you do (x+2)^2 which is x^2+2x+4

Subtract 16 from both sides

4x^2 +8x = 0

factor out 4x:

4x(x+2) = 0

Answer:

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. The probability that exactly 8 tails occur is 0.1963.

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

P(x) = ⁿCₓ (pˣ) (q⁽ⁿ⁻ˣ⁾)

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

The probability of a tail occurring is 0.5, while the probability of a tail, not coming is 0.5, therefore, we can write p=0.5 and q=0.5.

Now, the probability of exactly 8 tails occurring can be written as,

P(X=8) = ¹⁶C₈ (0.5)⁽⁸⁾ (0.5)⁽¹⁶⁻⁸⁾

P(X=8) = 12,870 (0.5)¹⁶

P(X=8) = 0.1963

Hence, the probability that exactly 8 tails occur is 0.1963.
