In 1903, Crayola's very first box of crayons had 8 colors. Today there are 120 Crayola crayon colors to choose from. find the percent change.

Answers

Answer 1

Answer:

Step-by-step explanation:

To find the percent change, we can use the formula:

percent change = (final value - initial value) / initial value * 100

In this case, the initial value is 8 and the final value is 120. Plugging in the values, we get:

percent change = (120 - 8) / 8 * 100 = 1,400%

So, the percent change in the number of Crayola crayon colors is 1,400%. This represents a significant increase from the initial 8 colors in 1903.

On evaluating, the function f(x) and g(x) the values of f(g(3)) = - 11 and f(g(x)) = -35x + 22.    

Evaluating functions:  

A relation between a collection of inputs and outputs is known as a function. A function is an association between inputs in which each input is connected to approximately one output. To find f(a) for a given function f(x) we simply substitute 'a' instead of 'x' in the given function f(x).

   

Here we have

f(x) = 7x - 5 and g(x) = - 5x + 4

10. f(g(3))  

To find g(3) take x = 3 in g(x)

=> g(3) = - 5(3) + 4 = - 15 + 4 = 11  

=> g(3) = - 11

To find f(g(3))  take x = g(x) = - 11 in f(x)

f(g(3)) = 7(-11) - 5 =  - 77 - 5 = - 82

∴ The value of f(g(3)) = - 11  

11. f(g(x)

To find f(g(x)) take x = g(x)

=>  f(g(x) = 7(-5x + 4) - 5  

=>  f(g(x)) = -35x + 28 - 5

=>  f(g(x)) = -35x + 22  

∴ f(g(x)) = -35x + 22    

Therefore,

below sea level?

Answers

Submarine 2 will reach a depth of -1,056 feet below sea level in the fastest time.

It will take the faster submarine 44 minutes to reach a depth of -1,056 feet below sea level.

How to determine which submarine will reach a depth of -1,056 feet below sea level in the fastest time?

Since the proportional equation for Submarine 1 is y = -22x.

In order to determine which submarine will reach a depth of -1,056 feet below sea level in the fastest time, we need to find the proportional equation for Submarine 2 using the graph.

From the graph:

proportionality constant = depth/time

proportionality constant = -120/5 = -24

y = -24x

Since the proportionality constant of Submarine 2 (-24) is greater than that of Submarine 1 (-22). Thus, Submarine 2 will reach a depth of -1,056 feet below sea level in the fastest time.

The faster submarine is Submarine 2:

y = -24x

y = -1,056 feet

-1,056 = -24x

x= 1,056/24

x = 44 minutes

[tex]\cos \theta=\dfrac{2}{3}[/tex]

[tex]\sin \theta=-\dfrac{\sqrt{5}}{3}[/tex]

Step-by-step explanation:

To find the exact values of the trigonometric functions of θ, we can use the following trigonometric identities:

[tex]\boxed{\begin{minipage}{4 cm}\underline{Trigonometric Identities}\\\\$\sec x=\dfrac{1}{\cos x}$\\\\\\$\tan x=\dfrac{\sin x}{\cos x}$\\\\\\$\sin^2x+\cos^2x=1$\\\end{minipage}}[/tex]

In quadrant IV, cosine of the angle is positive, whereas sine of the angle is negative.

Given that sec θ = 3/2, and secant is the reciprocal of cosine:

[tex]\sec \theta=\dfrac{3}{2}[/tex]

[tex]\dfrac{1}{\cos \theta}=\dfrac{3}{2}[/tex]

[tex]\boxed{\cos \theta=\dfrac{2}{3}}[/tex]

To find sin θ, we can substitute the found value of cos θ into the Pythagorean identity:

[tex]\sin^2 \theta+\cos^2 \theta=1[/tex]

[tex]\sin^2 \theta+\left(\dfrac{2}{3}\right)^2=1[/tex]

[tex]\sin^2 \theta=1-\left(\dfrac{2}{3}\right)^2[/tex]

[tex]\sin \theta=\sqrt{1-\left(\dfrac{2}{3}\right)^2}[/tex]

[tex]\sin \theta=\dfrac{\sqrt{5}}{3}[/tex]

As sine of the angle is negative in quadrant IV:

[tex]\boxed{\sin \theta=-\dfrac{\sqrt{5}}{3}}[/tex]

Finally, substitute the values of sin θ and cos θ into the tan θ identity to find tan θ:

[tex]\tan \theta=\dfrac{\sin \theta}{\cos \theta}[/tex]

[tex]\tan \theta=\dfrac{-\frac{\sqrt{5}}{3}}{\frac{2}{3}}[/tex]

[tex]\boxed{\tan \theta=-\dfrac{\sqrt{5}}{2}}[/tex]

Therefore, the exact values of the trigonometric functions for θ are:

The relative speed is the net speed of two different objects with respect to each other.

If two objects move in the same direction we take the difference between their speeds.

If two objects move in the opposite direction we take the sum of their speeds.

We can utilize the following parameters in our calculation based on the question,

Time = 4 pm

Distance = 64 km

Calculate how long it took the father to ride his horse and the son to walk the first 32 miles.

Time = Distance / (Difference between rates of father and son)

Time = 32 km / (8 km/h - 3 km/h)

Time = 32 km / 5 km/h

Time = 6.4 hours

Determine how long it will take the father to walk the final 32 miles and the son to ride the horse.

Time = Distance / (Difference in Speed)

Time = 32 km / (8 km/h - 4 km/h)

Time = 32 km / 4 km/h

Time = 8 hours

The length of a rectangle is 5 cm, and the width is 4 cm. If both the length and the width are increased by equal amounts, the are of the rectangle is increased by 70 cm2. Find the length and width of the longer rectangle.

Answers

Answer:

Length = 10cm, Width = 9 cm

Step-by-step explanation:

Let's call the amount that both the length and width are increased by "x". So, the new length is 5 + x and the new width is 4 + x.

The original area of the rectangle was 5 * 4 = 20 cm2.

The new area of the rectangle after the increase is (5 + x) * (4 + x) = 20 + 70 + 2x^2.

Expanding the right-hand side, we have 20 + 70 + 2x^2 = 90 + 2x^2.

Equating the two areas, we get:

20 + 70 + 2x^2 = 90 + 2x^2

Subtracting 2x^2 from both sides:

20 + 70 = 90

Subtracting 20 from both sides:

70 = 70

So x^2 = 50 / 2 = 25.

Taking the square root of both sides, we get:

x = 5

So the length of the longer rectangle is 5 + x = 5 + 5 = 10 cm, and the width is 4 + x = 4 + 5 = 9 cm.

Answers

In this population of 100 individuals, approximately 49 individuals will have green hair due to the dominant allele CC and approximately 42 individuals will have green hair due to the dominant allele Cc. The total number of individuals with green hair is 49 + 42 = 91.

What is the quadratic equation?

A quadratic equation in one variable is a mathematical sentence of degree 2 that can be written in the following standard form. a+ bx + c = 0, where a, b, and c are real numbers and a 0.

The Hardy-Weinberg equilibrium is an idealized model of a population that assumes that the frequency of alleles remains constant from generation to generation in the absence of external forces.

According to this model, the frequency of a particular genotype can be calculated using the following formula:

p² + 2pq + q² = 1

where p is the frequency of the dominant allele (C) and q is the frequency of the recessive allele (c). In this case, p = 1 - q = 1 - 0.3 = 0.7, and q = 0.3.

The frequency of individuals with the genotype CC (green hair) is given by p², or 0.7² = 0.49.

The frequency of individuals with the genotype Cc (green hair) is given by 2pq, or 2 * 0.7 * 0.3 = 0.42.

Hence, in this population of 100 individuals, approximately 49 individuals will have green hair due to the dominant allele CC and approximately 42 individuals will have green hair due to the dominant allele Cc. The total number of individuals with green hair is 49 + 42 = 91.

A model rocket is launched with an initial upward velocity of 50m / s The rocket's height (meters) after seconds is given by the following h = 50t - 5t ^ 2

Answers

The complete question

A model rocket is launched with an initial upward velocity of 50m/s. The rocket's height h (in meters) after t seconds is given by the following. h=50t-5t².

Find all values of t for which the rockets height is 20 meters.

The values of t for which the rockets height is 20 meter are, (10 + 2√21) / 2  and (10 - 2√21) / 2

What is velocity ?

Velocity is a vector quantity that represents the rate of change of an object's position. It is defined as the derivative of the position vector with respect to time and has units of meters per second (m/s). Velocity includes both speed and direction, and is an important concept in physics and engineering.

We can find the values of t for which the rocket's height is 20 meters by setting h equal to 20 and solving for t.

h = 50t - 5t² = 20

Expanding the equation, we have:

50t - 5t² = 20

Adding 5t² to both sides:

50t = 20 + 5t²

Dividing by 5 both the sides,

10t = 4 + t²

t² - 10t + 4 = 0

t = (10 + 2√21) / 2

and t = (10 - 2√21) / 2

So the values of t for which the rocket's height is 20 meters are

(10 + 2√21) / 2  and (10 - 2√21) / 2

What is division?

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

wen and five friends equally share 1/3 of a pan of snack bars.

so, we get,

the expression is 1/3 ÷ 6

This is because there are 6 friends in all and you are splitting 1/3 of the pan snack bars to each of them.

So, what your splitting/cutting/dividing would be the dividend (1/3) and then the friends would be the divisor (6)
