So, Event A has 13/52 outcomes.

The question is about translating the graph of the function y = 3/x. The graph of y = 3/(x - 1) + 3 results from shifting the parent function to the right by 1 unit and upwards by 3 units on the coordinate grid.

The question pertains to the translation of a rational function on the coordinate grid and is related to graph transformations. The function y = 3/x is known as the parent function, and y = 3/(x - 1) + 3 is the transformed function. To illustrate the translation, we can understand the changes in terms. Here x - 1 indicates a horizontal shift to the right by 1 unit, and +3 signifies a vertical shift upwards by 3 units. The new graph represents these translations on the coordinate system, which is a two-dimensional representation with x and y-axes as described in the reference information provided.

Answer:

[tex]x=7 \frac{3}{7}[/tex] gallons

Step-by-step explanation:

So we are given:

70 miles   ->  1 gallon is used.

520 miles ->  x gallons is used.

Set up a proportional to solve.

I lined up everything already above:

[tex]\frac{70}{520}=\frac{1}{x}[/tex]

Cross multiply:

[tex]70(x)=520(1)[/tex]

[tex]70x=520[/tex]

Divide both sides by 70:

[tex]x=\frac{520}{70}[/tex]

Reduce the fraction (divide top and bottom by 10):

[tex]x=\frac{52}{7}[/tex]

How many 7's are in 52?  7 because 7(7)=49

How much is left over after seven 7's go into 52? 52-49=3

So the answer as a mixed fraction is:

Answer:

The correct option is B

Step-by-step explanation:

Todd rolls two number cubes.

Let A={the sum of the number cubes is even}

A={2,4,6,8,10,12}

Let B={the sum of the number cubes is divisible by 2}

B = {2,4,6,8,10,12}

Now we have to find A∩B

Intersection refers to the values which are common in both the sets. The sums in both sets are even and divisible by 2.

So,

A={2,4,6,8,10,12} B = {2,4,6,8,10,12}

A∩B = {2,4,6,8,10,12}

Thus the outcomes A∩B = {2,4,6,8,10,12}

Step-by-step explanation:

we know that          

An inscribed circle is the largest circle contained within the triangle. The center of the circle inscribed in a triangle is the incenter of the triangle.

The incenter is the point where the angle bisectors of the triangle intersect.

The circumscribed circle is the circle that passes through all three vertices of the triangle. The center of the circumscribed circle is called the circumcenter of the triangle

The circumcenter is the point where the perpendicular bisectors of the sides intersect.

therefore

The circumcenter of a triangle is the center of the only circle

that can be circumscribed about it.

Answer:

2 cm base, 3 cm height

Step-by-step explanation:

Let

x -----> the height of one of the identical triangles pieces of the plane

y ----> the base of one of the identical triangles pieces of the plane

we know that

x=3 cm

2y+2=6

solve for y

2y=6-2

2y=4

y=2 cm

therefore

The dimensions of one of the identical triangles pieces of the plane are 2 cm base and 3 cm height

Answer:

The correct option is 1. The dimensions of one of the identical triangular pieces of the plane are 2 cm base and 3 cm height.

Step-by-step explanation:

From the given figure it is noticed that the length of parallel sides of the trapezoid are 6 cm and 2 cm.

The height of triangular pieces is same as the height of trapezoid. So the height of triangular pieces is 3 cm.

Let the measure of base of the triangular pieces be x.

[tex]x+2+x=6[/tex]

Combine like terms.

[tex]2x+2=6[/tex]

Subtract 2 form both the sides.

[tex]2x+2-2=6-2[/tex]

[tex]2x=4[/tex]

Divide both sides by 2.

[tex]x=\frac{4}{2}[/tex]

[tex]x=2[/tex]

The base of the triangles is 2 cm.

The dimensions of one of the identical triangular pieces of the plane are 2 cm base and 3 cm height. Therefore the correct option is 1.

Rewrite 1/2 to have a common denominator with 2/6

1/2 x 3 = 3/6

Now you have 1 and 3/6 - 2/6  = 1 and 1/6

Now rewrite 2/3 to have a common denominator with 1/6: 2/3 x 2 = 4/6

Subtract 1/6 from 4/6:

4/6 - 1/6 = 3/6 = 1/2

You will need to add 1/2

To get from the difference between 1 and 1/2 and 2/6 to 1 and 2/3, one must add 1/2 after ensuring both differences have a common denominator.

To find out what should be added to the difference between 1 and 1/2 and 2/6 to get 1 and 2/3, we need to perform a few steps involving fractions. First, let's convert 1 and 1/2 into an improper fraction by multiplying 1 (the whole number) by 2 (the denominator of the fractional part) and adding 1 (the numerator of the fractional part), which gives us 3/2. Now, to find the difference between 3/2 and 2/6, we must have a common denominator, which is 6 in this case. Multiplying the numerator and denominator of 3/2 by 3 gives us 9/6.

Now we subtract 2/6 from 9/6 to get the difference, which is 7/6 or 1 and 1/6. To find what needs to be added to this difference to get 1 and 2/3, we must also express 1 and 2/3 as an improper fraction. Multiplying 1 (the whole number) by 3 (the denominator) and adding 2 (the numerator) gives us 5/3.

To compare 7/6 with 5/3, we need the same denominator, which is 6. So we multiply the numerator and denominator of 5/3 by 2 to get 10/6. Subtracting 7/6 from 10/6, we find the missing number to be 3/6, which simplifies to 1/2.

Answer:

1, 3, 5

Step-by-step explanation:

The sum of an arithmetic series is:

S_n = n (a_1 + a_n) / 2

100 = n (1 + 19) / 2

n = 10

The nth term of an arithmetic sequence is:

a_n = a_1 + d (n − 1)

19 = 1 + d (10 − 1)

d = 2

The common difference is 2.  So the first three terms are 1, 3, and 5.

Answer: [tex]\bold{focus: \bigg(2, -7 \dfrac{1}{8}\bigg), \quad directrix: y = -6 \dfrac{7}{8}}[/tex]

Step-by-step explanation:

First, rearrange the equation into vertex form: y = a(x - h)² + k   where

NOTE: p is the distance from the vertex to the focus

      y = -2x² + 8x - 15

y + 15 = -2x² + 8x            → added 15 to both sides

y + 15 = -2(x² - 4x)           → factored out -2 from the right side

y + 15 + (-2)(4) = -2(x² - 4x + 4)    → completed the square

y + 7 = -2(x - 2)²                → simplified

     y = -2(x - 2)² - 7           → subtracted 7 from both sides

Now it is in vertex form where:

Focus = (2, -7 + p)  →  Focus = (2, -7 + (-1/8))   →  [tex]Focus = \bigg(2, -7 \dfrac{1}{8}\bigg)[/tex]

Directrix: y = -7 - p   →  Directrix: y = -7 - (-1/8)   →  [tex]Directrix: y = -6 \dfrac{7}{8}[/tex]

The formula for computing the sum of an infinite geometric series is

[tex]S=\frac{a_1}{1-r}[/tex] where r is between -1 and 1 and [tex]r[/tex] is the common ratio, and [tex]a_1[/tex] is the first term of the series.

So let's plug in:

[tex]S=\frac{0.3}{1-0.1}[/tex]

[tex]S=\frac{0.3}{0.9}[/tex]

[tex]S=\frac{3}{9}[/tex] I multiplied bottom and top by 10.

[tex]S=\frac{1}{3}[/tex] I divided top and bottom by 3.

The sum is 1/3.

The sum of the infinite geometric series is 1 / 3.

When there is a constant between the two successive numbers in the series then it is called a geometric series. In other words, every next term is multiplied with that constant term to form a geometric progression.

Given that the first term a₁ = 0.3 and common ratio r = 0.1. The sum of the geometric series is calculated by using the formula below:-

S = a₁ / ( 1 - r )

S = 0.3 / ( 1 - 0.1 )

S = 0.3 / 0.9

S = 3 / 9

S = 1 / 3

Therefore, the sum of the infinite geometric series is 1 / 3.
