Ellen is playing a video game in wich she captures butterflies/ There are 3 butterflies onscreen, but the number of butterflies doubles every minute. After 4 minutes, she was able to capture 7 of the butterflies.

Write an expression for the number of butterflies after 4 minutes. Use a power of 2 in your answer

Answer:

x=14

Step-by-step explanation:

Half circle total degree is 180°

180°=(2x-4)+101°+47°

so, 2x-4=180-101-47

     2x-4=32

     2x=32-4

      2x=28

       x=14

The two equations have thesame slope therefore , the system has no solution

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 14 4x − 4y = 4.

y = 2/3x - 7

multiply all by 3

3y = 2x -21

3y -2x = -21

2x - 3y = 21 equation 1

2x -3y = 21 equation 2

The two equations has thesame slope,

Since equation 1 is equal to equation 2 , the system has no solution

The solution to the two functions f(x) = 3ˣ and g(x) = -x + 4 is, 1

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

The number of visitors increases exponentially as the temperature increases, and this situation can be  expressed by the function

f(x) = 3ˣ

The number of people who leave the park early depending on the change in temperature, and it  can be  expressed  by the function,

g(x) = −x + 4

the solution of both the graphs = ?

the intersection of the two curves of graphs of the functions is the solution,

Basically, it represent that,

both function have same value for particular value of x,

So,

when both functions have same value that will be our solution,

f(x) = 3ˣ

g(x) = −x + 4

it is shown in the graph, both functions are intersecting each other at x = 1

f(1) = 3

g(1) = −1 + 4 = 3

The standardized value for x = 2.69 is 0.

The standardized value (z) is given by:

z = (x - mean) / standard deviation

where x is the value to be standardized, mean is the normal distribution's mean, and standard deviation is the normal distribution's standard deviation.

So, for x = 2.69, with a mean of 2.69 and a standard deviation of 4.76, the standardized value (z) is:

z = (2.69 - 2.69) / 4.76 = 0

As a result, the standardized value for x = 2.69 is 0.

Standard deviation is a measure of the spread or dispersion of a set of data values around their mean (average). It provides a quantitative indication of how far apart each data value is from the mean and from each other. A low standard deviation means that the data values are close to the mean, while a high standard deviation indicates that the data values are more spread out.

The probability of drawing a jack or a queen or a heart from a standard 52-card deck is 1/4.

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

There are a total of 52 cards in a standard playing deck, and there are 4 jacks, 4 queens, and 13 hearts.

The probability of drawing a jack or a queen or a heart is equal to the sum of the probabilities of drawing each individual card type.

So, the desired probability is:

P(jack or queen or heart) = P(jack) + P(queen) + P(heart)

= 4/52 + 4/52 + 13/52

= 21/52

B) The estimate value of the instanteneous velocity when t = 1s is equals to -22 ft/s.

The average velocity over an interval [a,b] for a defined position function f(t) can be displayed by the difference quotient {f(b)-f(a)}/{b-a}. When these two points come very close to each other and at any point both of them appear almost the same point then the average velocity becomes instantaneous velocity at that time, which is also the derivative of the function at that point. We have, baby alien throw a ball into the air with a velocity of 24 ft/s on planet. The height in feet or

the displacement relation is defined as ,

y (t) = 24t - 23t².

where, y--> displacement/height

t --> time

Initial time , to = 1 sec

Therefore, the velocity will be

dy/dt = v(t) = 24 - 46t

A) The average velocity on an interval [a,b] is

Vₐᵥ = { y( b) - y(a) }/(b - a)

Now, see the intervals ,

Vₐᵥ = {y( 1.01) - y(1)}/(1.01 - 1)

= {24(1.01) - 23(1.01)² - 24×1 + 23× 1 }/0.01

= {24.24 - 24 - 23.4623 + 23}/0.01

Vₐᵥ = {y( 1.005) - y(1)}/(1.005 - 1)

= {24(1.005) - 23(1.005)² - 24×1 + 23× 1 }/0.005

= -22.115 ft/s

Vₐᵥ = {y( 1.001) - y(1)}/(1.001 - 1)

= {24(1.001) - 23(1.001)² - 24×1 + 23× 1 }/0.001 = { 24.024 - 24 + 23 - 23(1.001)²}/0.001 = - 22.023 ft/s

B) The instanteneous velocity is defined as V (t) = dy/dt = 24 - 46t

At t = 1 s then V(t) = 24 - 46(1) = 24 - 46

The displacement of the particle at t = 1 second is -3 .meters

The displacement of a particle in a straight line can be calculated using the following formula:  Displacement (d) = 2sin(πt) + 3cos(πt). This formula takes into consideration the sine and cosine of the angle, pi (π), multiplied by the time (t). The sine of the angle represents the vertical displacement, while the cosine represents the horizontal displacement.

For example, let's say we want to calculate the displacement of a particle at t = 1 second. First, we'll plug in the values into the formula:

d = 2sin(πt) + 3cos(πt)

d = 2sin(π*1) + 3cos(π*1)

d = 2sin(π) + 3cos(π)

d = 0 + (-3)

d = -3

Alternate interior angles are never supplementary would be two parallel lines being intersected by a transversal, such that one pair of alternate interior angles measures 180 degrees (i.e., they are supplementary). This would show that the statement is false and that alternate interior angles can indeed be supplementary.

When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines.

A transversal intersection of two parallel lines produces same-side interior angles, whose sum is 180 degrees. As the sum of the same side interior angles is 180 degrees therefore the angles are supplementary.

The volume of the solid generated by revolving the plane region about the x-axis is 125/6 units3.

The volume of the solid generated by revolving the plane region about the x-axis can be found by using the Shell Method. This method involves integrating the area of the cross-section of the solid with respect to the x-axis. The area of the cross-section can be found by calculating the area of the region bounded by the curve y=x and the origin, which is a triangle. The area of the triangle is 1/2 * base * height, or 1/2 * x * x. The definite integral that represents the volume of the solid is then given by:

[tex]V = ∫0 x (1/2 x2) dx[/tex]

cos x = 1 − x2/2! + x4/4! − x6/6! + x8/8! − x10/10! + . . .

For|x| < 1/2, we can ignore the higher order terms, and thus the series reduces to:
