The lowest and leftmost note on a piano keyboard is an A. The next lowest A is seven white keys to the right. This pattern continues. Write an explicit formula for an arithmetic sequence to represent the position of each A key on the piano, counting from the left. If a piano has 52 white keys, in what position is the key that plays the highest A?

Answer:

There were 18 1 point goals and 40 2 point goals

Step-by-step explanation:

Let the number of one point shots be x and the number of two point shots be y

Total number of shot is 58

x + y = 58 ••••(i)

Then;

Total of 1 point is 1 * x = x

Total of 2 points is 2 * y = 2y

x + 2y = 98 ••••••(ii)

x = 98-2y

Put this in 1

98-2y + y = 58

-y = 58-98

y = 40

x = 58-40

x = 18

Answer:

The slope here is - 5

g=15

g=5

hope U mean this.

Answer:

g = 5

Step-by-step explanation:

First, find a number in common between 15 and 3, which is 5. If you divide 15 by 3 you'd know that g is 5.

Answer:

Step-by-step explanation:

first change the equation so it just equals y

-5y = 5 -4x

y = 4/5x -1

since this new equation has to be parallel to the previous line, the slopes are the same

y = 4/5x + b

now we have to make sure the new equation passes through (-5,2) so we plug in -5 for x and 2 for y

2 = 4/5(-5) + b

2 = -4 + b

b = 6

so the final equation is

y = 4/5x +6

The equation of the line that passes through the point (-5,2) and is parallel  to the line 4x - 5y = 5 is 5y - 4x = 30

The equation of a line in point-slope form is expressed as:

[tex]y-y_0=m(x-x_0)[/tex]

m is the slope of the line

(x0, y0) is any point on the line

Given the equation 4x - 5y = 5.

Rewrite in standard form:

-5y = -4x + 5

y = 4/5 x - 1

The slope of the line passing through the given equation is 4/5

Substitute the slope and the point into the equation:

[tex]y-2=4/5(x+5)\\5(y-2)=4(x+5)\\5y-10=4x+20\\5y-4x=20+10\\5y-4x=30[/tex]

Hence the equation of the line that passes through the point (-5,2) and is parallel  to the line 4x - 5y = 5 is 5y - 4x = 30

Answer:

12

Step-by-step explanation:

The formula to find the area of a circle is:

[tex]\pi[/tex][tex]r^{2}[/tex]

Where "r" is the radius of the circle.

In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.

The equation will be:

3 * 2^2

Simplify, remember the order of operations:

3 * 4

Answer:

12.56 cm

Step-by-step explanation:

Area of a circle is A=3.14 r to the second power.

so the radius is 2 cm. I would do 2 x 2 and that equals ,4 next 4 x 3.14= 12.56

2) -13+9

3) -5+(8)

I don't quite know how to explain

Just think about 1) 60 is the new temperature, in order to have an addition problem we're going to have to use negative numbers. Since we had to subtract 20, in order to use addition it would be 80+(-20).

Answer:

4x + 3y = - 12

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y = - [tex]\frac{4}{3}[/tex] x - 4 ( multiply through by 3 to clear the fraction )

3y = - 4x - 12 ( add 4x to both sides )

4x + 3y = - 12 ← in standard form

Answer:

The smallest of the three is 32

Step-by-step explanation:

you can divide 99 by three and get the middle number of the three numbers

Answer:

32

Step-by-step explanation:

32+33+34=99

Given:

[tex]y=-x^2+5x+14[/tex]

To find:

The interval on which the given function is positive.

Solution:

We have,

[tex]y=-x^2+5x+14[/tex]

Splitting the middle term, we get

[tex]y=-x^2+7x-2x+14[/tex]

[tex]y=-x(x-7)-2(x-7)[/tex]

[tex]y=(x-7)(-x-2)[/tex]

[tex]y=-(x-7)(x+2)[/tex]

Using zero product property, we get

[tex]x-7=0\text{ and }x+2=0[/tex]

[tex]x=7\text{ and }x=-2[/tex]

-2 and 7 divide the number line is three interval.

Interval             Signs of [tex]y=-(x-7)(x+2)[/tex]         Result

(-∞,-2)                             (-)(-)(-)                           Negative    

(-2,7)                              (-)(-)(+)                           Positive    

(7,∞)                               (-)(+)(+)                          Negative    

So, the function is positive for the interval (-2,7), i.e., -2 < x < 7.

Therefore, the correct option is D.

Answer:

Continuous

Step-by-step explanation:

Given

[tex]Rate = 1.2\ miles/hour[/tex]

Required

Determine if this relationship is discrete or continuous

Numbers in their whole form (i.e. 1,2,3.....) represent discrete values while others with decimals (such as 0.2,0.9, 1.2...) represent continuous values

From the above analysis, we can see that 1.2 fall in the category of continuous values.

Hence, the relationship between both parameters is continuous
