hello : x = 14

Step-by-step explanation:

g(x)=20

solve this equation :

2(x-4) =20

divid by 2

x - 4  =10

add 4:

x = 14

Answer:

1) 6x = 21

2) x + y - 3

3) x/z = y

4) 2-x = p

Step-by-step explanation:

1. The product of a number x and 6 is 21

A product is a multiplication.  A product of a and b is a * b.

We then have a product of x and 6, that x * 6, which we write usually in the format 6x.

is 21: that means it's equal to 21....

so 6x = 21.

2. The sum of the quantity x- 3 and y  

The sum is an addition.  The sum of a and b is a + b.

In this case, the first part is x - 3, the second part is y

So, x - 3 + y, which we usually rewrite as x + y - 3

3. The quotient of x and z is y

A quotient is a division.

So, quotient of x and z is x/z.

x/z = y

4. The difference of 2 and x is p.

A difference is a subtraction.

Difference of 2 and x is 2 - x

2 - x = p

The verbal sentences/phrases are translated into algebraic expressions or equations as: 1) 6x = 21, 2) (x - 3) + y, 3) y = x/z, and 4) p = 2 - x. Each expression/equation captures a different mathematical relationship, such as product, sum, quotient, and difference.

To translate each verbal sentence/phrase into an algebraic expression or equation, we will take them one at a time:

Step-by-step explanation:

Answer:

41.4%

Step-by-step explanation:

The formula for determining the frequency: [tex]f(h)=440(2)^{\frac{h}{12}}[/tex]  --A

where h is the number of half-steps from the A above middle C on the keyboard.

A note is six half-steps away from the A above middle C.

Now we are supposed to find How much greater is the frequency of the new note compared with the frequency of the A above middle C?

Now initially there is no half steps .

So, substitute h =0

[tex]f(0)=440(2)^{\frac{0}{12}}[/tex]

[tex]f(0)=440[/tex]

Now we are given that A note is six half-steps away from the A above middle C

So, substitute h =6

[tex]f(6)=440(2)^{\frac{6}{12}}[/tex]

[tex]f(6)=622.25[/tex]

Now To find change percentage

Formula: [tex]=\frac{\text{final} - \text{initial}}{\text{Initial}} \times 100[/tex]

                [tex]=\frac{622.25- 440}{440} \times 100[/tex]

               [tex]=0.414 \times 100[/tex]

               [tex]=41.4\%[/tex]

Hence  the frequency of the new note is 41.4% greater with the frequency of the A above middle C.

Answer:B

Step-by-step explanation:

We can see here that the remainder of the given division problem is: B) 1

Division is an arithmetic operation that involves the splitting or sharing of a quantity into equal parts or groups. It is the inverse operation of multiplication. When we divide one number by another, we are determining how many times the divisor can be subtracted from the dividend.

The division process involves repeatedly subtracting the divisor from the dividend until no more subtractions are possible, or until the remainder is less than the divisor.

We can see here that as we subtract x from x, we have 0 and then we bring the 1 down. The 1 brought down is the remainder.

Edge

Answer:

(0,-2), (5,0) and (10,2).

Step-by-step explanation:

Given equation is [tex]2x-5y=10[/tex].

Now we need to find 3 pairs of solutions in (x,y) form for the given equation.

As [tex]2x-5y=10[/tex] is a linear equation so we are free to pick any number for x like x=0, 5, 10

Plug x=0 into [tex]2x-5y=10[/tex], we get:

[tex]2(0)-5y=10[/tex]

[tex]0-5y=10[/tex]

[tex]-5y=10[/tex]

[tex]y=\frac{10}{-5}[/tex]

[tex]y=-2[/tex]

Hence first solution is (0,-2)

We can repeat same process with x=5 and 10 to get the other solutions.

Hence final answer is (0,-2), (5,0) and (10,2).

The answers is:

The three points that are solution for the equation are:

[tex](5,0)\\(0,-2)\\(6,0.4)[/tex]

To find 3 pairs (x,y) or points that are solutions for the equation, we could find where the function intercepts the x-axis and y-axis, we must remember that the domain of a line is all the real numbers, so by using any input, we will find a solution, which means finding a point that belongs to the line.

So,

Finding the axis intercepts of the line, we have:

x-axis intercept:

Making "y" equal to 0, we have:

[tex]2x-5y=10[/tex]

[tex]2x-5*(0)=10[/tex]

[tex]2x=10[/tex]

[tex]x=\frac{10}{2}=5[/tex]

We have that the interception point with the x-axis is (5,0)

y-axis intercept:

Making "x" equal to 0, we have:

[tex]2x-5y=10[/tex]

[tex]2*(0)-5y=10[/tex]

[tex]0-5y=10[/tex]

[tex]5y=-10[/tex]

[tex]y=\frac{-10}{5}=-2[/tex]

We have that the interception point with the y-axis is (0,-2)

As we know, the domain of a line is equal to the real numbers, Now, we have that any between the points (5,0) and (0,-2) will belong to the line, so, let's try with a point wich x-coordinate (input) is equal to 6 and then find the y-coordinate (output) if the point satisfies the equality, it belongs to the equation to the line.

Substituting x equal to 6, we have:

[tex]2*(6)-5y=10[/tex]

[tex]12-5y=10[/tex]

[tex]12-10=5y[/tex]

[tex]y=\frac{12-10}{5}=\frac{2}{5}[/tex]

So, the obtained point is:

[tex](6,\frac{2}{5})[/tex]

or

[tex](6,0.4)[/tex]

Now, let's prove that it belongs to the equation of the line by substituting it into the equation:

[tex]2*(6)-5*\frac{2}{5}=10[/tex]

[tex]12-2=10[/tex]

[tex]10=10[/tex]

We can see that the equality is satisfied, it means that the point belongs to the line.

Hence, the three points that are solutions for the equation are:

[tex](5,0)\\(0,-2)\\(6,0.4)[/tex]

Answer:

Watson's garden shop has the better deal on the lawn mower.

Hope this helped :)

Step-by-step explanation:

Watson's $130 - 50% = $65

Hartman's $130 - 40% = $78

                  $78 - 15% = About $66

Answer:

The deal of Watson’s garden shop is better.

Step-by-step explanation:

Given,

The original price = $ 130,

After 50% off,

The new price would be,

[tex]P_1=130\times \frac{(100-50)}{100}[/tex]

[tex]=\frac{130\times 50}{100}[/tex]

[tex]=\frac{6500}{100}[/tex]

[tex]=\$ 65[/tex]

While, after 40% off then additional 15% off,

The new price would be,

[tex]P_2= 130\times \frac{(100-40)}{100}\times \frac{(100-15)}{100}[/tex]

[tex]=130\times \frac{60}{100}\times \frac{85}{100}[/tex]

[tex]=\frac{663000}{10000}[/tex]

[tex]=\$ 66.30[/tex]

Answer:

W

Step-by-step explanation:

On the venn diagram, you can see that everything in the W section is a multiple of 7. Everything in the Z section is an even number and everything in Y(the middle section) is both an even number and a multiple of 7. Since 49 is a multiple of 7 but not an even number, it would go in the W section.

The number 49 should be placed in the 'W' portion of the venn diagram

From the venn diagram, we can make the following inference;

W = 7, 21, 35

Y = 14, 28

Both W and Y contains numbers that are multiples of 7

Y contains numbers that are even numbers which are multiples of 7

W contains numbers that are odd and are multiples of 7

The number 49 is also a multiple of 7 and odd.

Hence, 49 would belong to the 'W' portion of the Venn.

The quadratic equation in vertex form is f(x) = 0.4(x - 2)² + 5

How to determine the equation in vertex form

From the question, we have the following parameters that can be used in our computation:

The graph

Where, we have the vertex to be

(h, k) = (2, 5)

A quadratic equation in vertex form is represented as

f(x) = a(x - h)² + k

So, we have

f(x) = a(x - 2)² + 5

Using the points, we have

a = 0.4

Substitute the known values into the equation

f(x) = 0.4(x - 2)² + 5

Hence, the equation in vertex form is f(x) = 0.4(x - 2)² + 5

Answer:  D) 10 sin (πx) - 5

Step-by-step explanation:

The range (maximum - minimum) is 5 - (-15) = 20

The amplitude (A) is range (20) ÷ 2 = 10

The vertical shift (D) is maximum (5) - amplitude (10) = -5

Of the given options, only A & D are candidates.  Now we need to decide if it is a cos graph (A) or a sin graph (D).  If we shift the graph up 5 units (to eliminate the vertical shift) , the graph would pass through the origin.  Thus it is a sin graph and the answer must be option D.

The area of the quarter circle is [tex]16\pi\ cm^{2}[/tex]

Step-by-step explanation:

we know that

The area of a quarter circle is equal to

[tex]A=\frac{1}{4}\pi r^{2}[/tex]

we have

[tex]r=8\ cm[/tex]

substitute the value

[tex]A=\frac{1}{4}\pi (8)^{2}[/tex]

[tex]A=16\pi\ cm^{2}[/tex]

The area of a quarter circle with a radius of 8cm is 16π square cm. This result is obtained by first calculating the area of a full circle using the formula A = πr² and then dividing by 4 (since a quarter circle is one-fourth of a full circle).

The area of a full circle is given by the formula A = πr², where 'r' is the radius of a circle and 'π' is a mathematical constant, approximately 3.14. However, we are dealing with a quarter circle, not a full circle. A quarter circle is simply one-fourth of a full circle. Therefore, you have to divide the area of the full circle by 4 to get the area of the quarter circle.

So here's how you calculate the area of the quarter circle having a radius of 8cm:

So, the area of the quarter circle with a radius of 8 cm is 16π square cm.

Joe and Mike both participated in the same race, but Joe finished 4 minutes earlier than Mike. We know that Mike finished the race at 4:02 PM. To determine Joe's finish time, we need to subtract 4 minutes from 4:02 PM.

Therefore, Joe finished the race at 3:58 PM.

The Pythagorean Theorem is

[tex]a^2+b^2=c^2[/tex]

Where a and b are legs and c is the hypotenuse.

If we had the measurements 27, 36, and 45...

[tex]a^2+b^2=c^2 \\ \\ 27^2+36^2=45^2 \\ \\ 729+1296=2025 \\ \\ 2025 = 2025[/tex]

So it is a right triangle because [tex]a^2+b^2=c^2[/tex]

The values of a, b, and c are given.

[tex]a=27 \\ b=36 \\ c=45[/tex]

Converse blanks: the sum of the legs squared is equal to the square of the hypotenuse; right.

a = 27, b = 36 (a and b can be switched), c = 45 --> the hypotenuse is always the longest side.

a² + b² = c²

Substitute: 27² + 36² = 45²

Simplify: 729 + 1296 = 2025

Simplify: 2025 = 2025

This is a right triangle because the sum of the lengths of the legs squared is equal to the length of the hypotenuse squared.

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = [tex]\frac{-20}{8}[/tex] = [tex]\frac{50}{-20}[/tex] = - 2.5

Multiplying each term by - 2.5 gives the next term

50 × - 2.5 = - 125

- 125 × - 2.5 = 312.5

312.5 × - 2.5 = - 781.25

The next 3 terms in the sequence are - 125, 312.5, - 781.25

The common ratio is -2.5

Next 3 terms after 50 are -125, 312.5, -781.25

A sequence ( increasing or decreasing)  having a pattern that the next term is found by multiplying the previous term with a constant term called common ratio, is called a geometric sequence. Common ratio can be positive or negative.

The given sequence is 8, -20, 50......

The common ratio is   [tex]\frac{-20}{8}= - 2.5[/tex]

Next term after 50 = {50 x (-2.5)} = -125

Next term after -125 = {(-125) x (-2.5)} = 312.5
