What is the square root of 5 multiplied by the square root of 5

Answer:

The arithmetic sequence given above has a first term (a1) equal to 3 and the common difference (d) equal to 6. The sum of the first n terms of the sequence is calculated through  the equation,

                               Sn = (n/ 2) x (2a1 + (n - 1) x d)

Substituting,

                               S22 = (22 / 2) x (2x3 + (22 - 1) x 6) = 1452

Therefore, the answer is the first choice, 1452. 

Step-by-step explanation:

Please mark brainliest and have a great day!

Answer:

1452.

Step-by-step explanation:

Sum of n terms = n/2  [2a1 + d(n - 1) ] where a1 = the first term and d = the common difference.

Here a1 = 3 and d = 9-3 = 6.

So S22 = 11 [2*3 + 6(22-1)]

=  11 * 132

=  1452

Answer:

1 solution

Step-by-step explanation:

The number of solutions will be one.

( i.e. the system of equation has a unique solution )

We are given a system of equations such that:

One of the equation has a negative reciprocal slope as compared to the other.

This means that the two lines are perpendicular.

Hence, the two lines will definitely meet or intersect at just one point and at right angles.

Also we know that the solutions  of a system of linear equations are the points where the two lines intersect.

Hence, we will have just one solution.

( since here the two lines will intersect at just one point )

[tex]log_{s}(56)[/tex]

EXPLANATION

The given logarithmic expression is:

[tex] log_{s}(4 \times 7) + log_{s}(2) [/tex]

Recall and use the product rule of logarithm

[tex] log_{a}(b) + log_{a}(c) = log_{s}(bc) [/tex]

We apply this rule to obtain,

[tex]log_{s}(4 \times 7) + log_{s}(2) = log_{s}(4 \times 7 \times 2) [/tex]

We multiply out the argument to get;

[tex]log_{s}(4 \times 7) + log_{s}(2) = log_{s}(56) [/tex]

The correct answer is

[tex]log_{s}(56)[/tex]

When the expression Log₅ (4•7) + Log₅ 2 is express as a single logarithm, the result obtained is Log₅ 56

Log₅ (4•7) + Log₅ 2

Log₅ (4 × 7) + Log₅ 2

Log₅ 28 + Log₅ 2

Recall

Log M + Log N = Log MN

Thus,

Log₅ 28 + Log₅ 2 = Log₅ (28 × 2)

Log₅ 28 + Log₅ 2 = Log₅ 56

Thus,

Log₅ (4•7) + Log₅ 2 = Log₅ 56

From the above illustration,

We can conclude that when Log₅ (4•7) + Log₅ 2 is written as a single log, the result is Log₅ 56

Answer:

here is the answer look at picture above

Answer:

Middle Answer.

Step-by-step explanation:

Given that Micah intends to spend less than $150 on paint and brushes

Hence

Cost of brushes+ cost of paint ≤ 150

150 ≥ Cost of brushes+ cost of paint

150 ≥ Cost of brushes+ (price of paint per gal) · (number of gallons)

Given that he buys x gal of paint,

For middle answer:

150 ≥ 42.21 + 21.64x (which matches the inequality in the question, so this is the right answer)

The 42.21 would represent the money spent on paintbrushes. This because the amount of money spent on paintbrushes doesn't change (it's a set amount). You can tell this by the fact that 42.21 is not being multiplied by anything (the 42.21 cannot change at all)

The 21.64x  is the cost of paint per gallon.

Cost of paint per gallon means that the cost changes depending on many gallons you are getting.

The 21.64 represents the cost of 1 gallon of paint, and the 'x' represents the number of gallons.

Speed_still  = 12.25 mi/h

Speed_current = 1.75 mi/h

Step-by-step explanation:

In the first trip, the motorboat goes upstream

Speed_boat = Speed_still - Speed_stream

The speed is defined as

Speed = Distance / time

This means

Speed_boat  = 21 miles/ 2 h = 10.5 mi/h

Then

Speed_still - Speed_stream = 10.5 mi/h

In the second trip:

Speed_boat = Speed_still + Speed_stream

Speed_boat  = 21 miles/ 1.5 h = 14 mi/h

Speed_still + Speed_stream = 14 mi/h

Then, the ystem of equations result

Speed_still + Speed_stream = 14 mi/h

Speed_still - Speed_stream = 10.5 mi/h

If we add them together

2*Speed_still  = 24.5 mi/h

Speed_still  = 12.25 mi/h

Speed_stream  = 14 mi/h - 12.25 mi/ h = 1.75 mi/h

Inverse of a relation

Reasoning:

the inverse of a function is a full function, this is just a set of pairs.  A set of pairs, or relation, where x and y values interchange are inverse of the relation.  A one to one function is when a function's inverse is also a function (doesn't have more than one y for each x) which can be tested for on the normal function's graph with a HORIZONTAL line test.  A normal parabola isn't one to one.  An onto function has to do with every value being used (I don't remember much about them, but once again this isn't a function, but rather a specific set of pairs/data)

Example of inverse of a relation:

Relation: {(0,5), (3,2)}

Inverse: {(5,0), (2,3)}

Example of inverse of a function:

f(x)=5x

f-1(x)=x/5

Table N 4

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

Verify the table 4

For x=1, y=2

so

y/x=2/1=2

For x=2, y=4

so

y/x=4/2=2

For x=3, y=6

so

y/x=6/3=2

therefore

The constant of proportionality k is equal to 2 and the equation is equal to

y=2x

The table 4 represent a direct variation, therefore is a possible ratio table for ingredients X and Y

Answer:

The correct option is 4.

Step-by-step explanation:

It given that recipe ingredients remain in a constant ratio no matter how many servings are prepared.

It means the relation between x and y is

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

where k is constant of proportionality.

We need to find a possible ratio table for ingredients X and Y for the given number of servings.

In table 1,

[tex]\frac{y_1}{x_1}=\frac{2}{1}[/tex]

[tex]\frac{y_2}{x_2}=\frac{3}{2}[/tex]

[tex]\frac{y_1}{x_1}\neq \frac{y_2}{x_2}[/tex]

Option 1 is incorrect.

In table 2,

[tex]\frac{y_1}{x_1}=\frac{2}{1}=2[/tex]

[tex]\frac{y_2}{x_2}=\frac{4}{2}=2[/tex]

[tex]\frac{y_3}{x_3}=\frac{8}{3}[/tex]

[tex]\frac{y_1}{x_1}\neq \frac{y_3}{x_3}[/tex]

Option 2 is incorrect.

In table 3,

[tex]\frac{y_1}{x_1}=\frac{2}{1}[/tex]

[tex]\frac{y_2}{x_2}=\frac{3}{2}[/tex]

[tex]\frac{y_1}{x_1}\neq \frac{y_2}{x_2}[/tex]

Option 3 is incorrect.

In table 4,

[tex]\frac{y_1}{x_1}=\frac{2}{1}=2[/tex]

[tex]\frac{y_2}{x_2}=\frac{4}{2}=2[/tex]

[tex]\frac{y_3}{x_3}=\frac{6}{3}=2[/tex]

[tex]\frac{y_}{x_1}=\frac{y_2}{x_2}=\frac{y_3}{x_3}[/tex]

Option 4 shows a possible  ratio table for ingredients X and Y for the given number of servings.

Therefore the correct option is 4.

Answer:

pentagon

Step-by-step explanation:

So at this point, we have a full rotation of 360 degrees round that point. The graph accounts for 36 degrees of that 360 degrees leaving 360-36=324 degrees left to be split between the three polygons at (Around) that point. So 324/3=108.  Now we got to figure out a polygon that has all of it's angles being 108 degrees.

We can usually find that if we know the number of sides of the polygon but we don't but here is the formula 180(n-2)/n=108

Cross multiply gives

108n=180(n-2)

Distribute

108n=180n-360

subtract 180n on both sides

-72n=-360

Divide both sides by -72

giving n=5

So a 5 side polygon is a pentagon

   Three identical regular polygons fitted together at one point are regular Pentagons.

   Measure of the interior angle of a polygon is given by,

Interior angle of a polygon = [tex]\frac{(n-2)\times 180^\circ}{n}[/tex]

Where 'n' = number of sides of the polygon

Let the number of regular polygons fitted together at one point = x

Therefore, sum of one interior angle of all polygons at a point = [tex]\frac{x(n-2)\times 180^\circ}{n}[/tex]

It has been given in the question "36° is the gap left when 3 identical regular polygons have fitted together at a point."

Therefore, sum of interior angles of all polygons joining at a point with the gap = [tex]\frac{3(n-2)\times 180^\circ}{n}+36^\circ[/tex]

Since, sum of angles at a point is always 360°.

[tex]\frac{3(n-2)\times 180^\circ}{n}+36^\circ=360^\circ[/tex]

[tex]\frac{3(n-2)\times 180^\circ}{n}=324^\circ[/tex]

[tex]540n-1080=324n[/tex]

[tex]540n-324n=1080[/tex]

[tex]216n=1080[/tex]

[tex]n=5[/tex]

  Therefore, polygons fitted at one point are Pentagons.

Center (h,k) is (1,-2) and radius r = 2

Step-by-step explanation:

We need to find the center and radius of the circle of the given equation:

[tex]x^2-2x+y^2+4y+1=0[/tex]

We need to transform the above equation into standard form of circle

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

where(h,k) is the center of circle and r is radius of circle.

Solving the given equation:

[tex]x^2-2x+y^2+4y+1=0[/tex]

Moving 1 to right side

[tex]x^2-2x+y^2+4y=-1[/tex]

Now making perfect square of x^2-2x and y^2+4y

Adding +1 and +4 on both sides of the equation

[tex]x^2-2x+1+y^2+4y+4=-1+1+4[/tex]

Now, x^2-2x+1 is equal to (x-1)^2 and y^2+4y+2 =(y+2)^2

[tex](x-1)^2+(y+2)^2=4[/tex]

Comparing with standard equation of circle:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

h = 1 , k =-2 and r =2 because r^2 =4 then r=2

So, center (h,k) is (1,-2) and radius r = 2
