ASAP PLEASE Express the function graphed on the axes below as a piecewise function.

Answer:

The answer is 912

Step-by-step explanation:

If the numbers cannot be repeated, there can be 5040 possible codes. The probability to select the correct code in first try will be 1/5040. If the digits can be repeated then there can be 10000 possible combinations.

The code can be of digits between 0 to 9. Hence we have a choice of 10 digits

If the number cannot be repeated then the first digit of the code can be selected in

10 ways.

Similarly the second, third and fourth can be selected in 9, 8, and 7 ways.

Hence the code can be formed in

10 X 9 X 8 X 7 ways

= 5040ways

Now out of these 5040 codes, there can be only one code.

The probability to select it in first try i

1/5040

If the digits can be repeated, then we can use 10 digits for every specific number. Hence there can be

10 X 10 X 10 X 10 ways

= 10000 codes.

For [tex]log_{10}{\frac{1}{x} }=-6.34[/tex], the value of x is  2187761.6

We know that logarithm of a number is nothing but the power to which a number must be raised to get some other values.

i.e., if  [tex]b^y=a[/tex] then [tex]log_b{a}=y[/tex]

similarly if  [tex]log_b{a}=y[/tex] then  [tex]b^y=a[/tex]  

Where, a and b are two positive real numbers

y is a real number

Here, a is called argument, and b is called the base of the logarithm.

Consider logarithmic equation,

[tex]log_{10}{\frac{1}{x} }=-6.34[/tex]

Comparing above equation with  [tex]log_b{a}=y[/tex] we get,

a = 1/x, b = 10 and y = -6.34

From definition of logarithm [tex]log_b{a}=y[/tex] then  [tex]b^y=a[/tex]  we get,

⇒ [tex]10^{-6.34}=\frac{1}{x}[/tex]

⇒ x = [tex]\frac{1}{10^{-6.34}}[/tex]

⇒ x = 10^(6.34)

Step-by-step explanation:

The length of the side opposite this angle of the hypotenuse is 12.51°.

A right triangle consists of the hypotenuse (longest side), the opposite(length of the leg) and the adjacent.

The angle at the corner is 90degrees

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle.

Given that,

Length of the leg = 10cm

angle opposite the side = 53.1 degrees

To get the hypotenuse,

sin θ = opposite/hypotenuse

sin 53.1 = 10/hypotenuse

hypotenuse = 10/sin53.1°

hypotenuse = 10/0.799

hypotenuse = 12.51

Therefore,

The length of the side opposite this angle of the hypotenuse is 12.51°.

Note that given the diagram showing joined Rectangles with the total area of the compound shape given as: ABCDEF = 36cm², the value of length AB = 4.5 or 9/2

A compound form is created by combining simple shapes. It's also known as a "composite" or "complex" form.

To solve for the value of AB,  lets start form the given:

Given that:

The area of the shape ABCDEF is 36 square centimeters.

From the given figure:

In the smaller rectangle, length of sides AB is x and BC is (2-4) cm.

In the larger rectangle, length of the sides DE is (x-2) and EF is 3x cm.

thus the area if the Smaller Rectangle is:

A(Small) = x(x-4)

= x² - 4x

The area of the larger rectangle will be:
A(Large)  = 3x(x-2)

= 3x² -6x

The total area of the shape will be:

A(Small) + A(Large) = 36

X²-4x+3x²-6x = 36
⇒ 4x² - 10x - 36 = 0; Divide both sides by 2

⇒2x² - 5x - 18 = 0

solving the above using the factoring method, we have:

⇒2x2-5x-18=0

⇒2x2-9x+4x-18=0

⇒x(2x-9)+2(2x-9)=0

⇒(2x-9)(x+2)=0

⇒(2x-9)=0or(x+2)=0

⇒ 2x = 9or x= -2

Thus, x = 9/2 or -2

Since the value of AB cannot be a negative value, thus the correct answer is: 9/2 or 4.5

The number of hours Natalie worked babysitting last week is 6hrs and the number of hours she worked landscaping last week is 2 hrs.

Let x be the number of hours Natalie worked babysitting and y be the number of hours she worked landscaping. Then, the total earnings were 11x + 10y = $86.

Also, x = 3y, because she worked 3 times as many hours babysitting as she did landscaping.

Substitute x = 3y into the first equation:

11(3y) + 10y = $86

Expanding the first term we get,

33y + 10y = $86

Combining terms,

43y = $86

Dividing both sides by 43 we get,

y = $2

So, Natalie worked y = 2 hours of landscaping.

To find the number of hours she worked babysitting, substitute y = 2 into x = 3y as follows -

x = 3(2) = 6

So Natalie worked x = 6 hours babysitting.

Step-by-step explanation:

If 3/5 of the flowers are red, then 2/5 of them are white. Since 9/20 of the roses are white, then 9/20*2/5=3/20 of all of the flowers are white roses. Subtracting the number of white roses from the total amount of white flowers will give us the fraction of how many of the flowers are white carnations. 2/5-3/20=5/20=1/4 of all of the flowers, which is 25% as a percentage.

The percent of all the flowers are white carnations is 255.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. With the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

3/5 of the flowers are red.

2/5 of them are white.

and, 9/20 of the roses are white.

fraction of white roses of all flower

= 9/20 x 2/5

There are no values of x that would make both equation 1 and equation 2 true at the same time.

To solve for the variables x in this system of linear equations, we need to find the values of x that satisfy both equation 1 and equation 2 simultaneously.

One way to do this is to use the substitution method. We can isolate x in equation 1 and substitute it into equation 2.

Starting with equation 1:

22x - 1 = -23

Adding 1 to both sides:

22x = -22

Dividing both sides by 22:

x = -1

Now, substitute x = -1 into equation 2:

11x + 121 = -1

Substituting x = 1:

11(-1) + 121 = -1

Expanding:

-11 + 121 = -1

Simplifying:

111 = -1

Since 111 is not equal to -1, we can conclude that there is no solution to the system of linear equations. In other words, there are no values of x that would make both equation 1 and equation 2 true at the same time.

The integral of a vector field along a curve can be calculated using the concept of line integrals.

The line integral of a vector field F along a curve C is defined as the sum of the dot product of the vector field and the infinitesimal change in position along the curve.

In the case of the vector field F(x,y) = i + xj, the line integral from point A to point B can be calculated as follows:

∫_C F(x,y) • dr = ∫_A^B (i + xj) • dr = ∫_A^B i dx + xj dx

Here, dr represents the infinitesimal change in position along the curve C, and the integrand represents the dot product of the vector field and the change in position.

The line integral can be evaluated using numerical methods or using Green's theorem, which relates the line integral of a vector field along a closed curve to the double integral of the curl of the field over the region enclosed by the curve.

The probability that a student chosen at random plays both football and cricket is 7/20.

The probability that a student chosen at random plays both football and cricket can be found by using the formula for conditional probability:

P(football and cricket) = P(football | cricket) * P(cricket), where P(football | cricket) is the probability of playing football given that the student plays cricket, and P(cricket) is the probability of playing cricket.

Out of the 21 students who play cricket, 14 of them play football as well, so P(football | cricket) = 14/21.

The probability of playing cricket is P(cricket) = 21/40 since there are 40 students in total and 21 of them play cricket. So, the probability that a student chosen at random plays both football and cricket is P(football and cricket) = (14/21) * (21/40) = 14/40 = 7/20.

Therefore, the main answer is the probability that a student chosen at random plays both football and cricket is 7/20.
