Which equation has an extraneous solution?

Answer:

Step 1:

Hit=9,8

Ball=5,4

R=7,0(This will be the hit point)

Step 2:

(Ball)B'=7+(7-5)4=(9,4)

BR: y-4=(0-4)/(7-5)(x-5)→→→→→→→→→→→→y=-2x+14

RB': y-4=(4-0)/(9-7)(x-9)→→→→→→→→→→→→y=2x-14

The ball will not fell into the hole by it's path.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

We will bet an absolute graph here of the path of the ball.

Starting point is where the ball is located is (5, 4).

The ball hits the wall at (7, 0)

Let's find the equation of the line through these points.

It is of the form y  mx + c, where m is slope and c is y intercept .

m = (0 - 4) / (7 - 5) = -2

⇒ y = -2x + c

Substitute (7, 0) in the above equation,

0 = (-2 × 7) + c

⇒ c = 14

The equation of the line is y = -2x + 14.

Since the graph is absolute, the return path of the ball from the wall must have same slope with opposite sign since the line is upwards.

Equation of the line is of the form,

y = 2x + d

Substitute (7, 0) in the above equation,

0 = (2 × 7) + d

⇒d = -14

Equation is y = 2x - 14

Substitute (9, 8) in the equation to check whether the ball will make the putt.

2x - 14 = (2 × 9) - 14 = 18 - 14 = 4 ≠ 8

Hence the ball does not fall into the hole.

Answer:

  a)  5 seconds

Step-by-step explanation:

Usually in such scenarios, we're interested in position and time where h(t) ≥ 0. For the given equation, that is 0 ≤ t ≤ 7.5. Values of t that are negative, and values of t that give h(t) a negative value are generally not of interest.

Then, the choice between a domain of [0, 1] and one of [0, 5] will depend on the reason for using the equation. We expect that the longer of these two domains is likely to be more reasonable:

Answer:

Multiplication, as you are multiplying each term by 4:

1*4 =4

4*4 = 16

16*4 = 64

Then, you can calculate the next term: 64*4= 256

Answer:

The given pattern can be obtained by a 'multiplication' operation.

Thus, option (C) is correct.

Step-by-step explanation:

Given the pattern

1, 4, 16, 64, ..

From the given pattern, it is clear that every next term can be obtained by multiplying the previous term by 4.

For example, the 2nd term 4 can be obtained by multiplying the previous term by 4.

Similarly, the 3rd term 16 can be obtained by multiplying the previous term (2nd term) by 4.

Also, the 4th term 64 can be obtained by multiplying the previous term (3rd term) by 4.

In a nutshell, the next term (5th term) can be obtained by multiplying the previous term (4th term) by 4.

This indicates that the following pattern can be obtained by a 'multiplication' operation.

Thus, option (C) is correct.

Answer:

[tex]\{0,1,2\}[/tex]

Step-by-step explanation:

Given:

[tex]\{(1, 3), (0, 4), (2, 1)\}[/tex]

Required

Determine the domain

A relation is represented as: [tex]\{(x_1, y_1), (x_2, y_2), (x_3, y_3).....(x_n,y_n)\}[/tex]

Where:

[tex]\{x_1,x_2,x_3.....x_n\}[/tex] are the domain of the relation

So, by comparison:

[tex]\{1,0,2\}[/tex] or [tex]\{0,1,2\}[/tex] represents the domain

Answer:

[tex]y = 4x-1[/tex]

Step-by-step explanation:

Required:

Determine the equation of the linear function

First, we need to determine the slope (m) as follows:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (-2,-9)[/tex]

[tex](x_2,y_2) = (4,15)[/tex]

Substitute these values in [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{15- (-9)}{4 - (-2)}[/tex]

[tex]m = \frac{24}{6}[/tex]

[tex]m =4[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y -(-9) = 4(x - (-2))[/tex]

[tex]y + 9 = 4(x + 2)[/tex]

[tex]y + 9 = 4x + 8[/tex]

Make y the subject

[tex]y = 4x + 8 - 9[/tex]

[tex]y = 4x-1[/tex]

Answer:

Sue has 8 marbles

Molly has 8 marbles

Step-by-step explanation:

m = number of marbles Molly has

s =  number of marbles that sue has

m+s =32

m = 3s

Substitute the second equation into the first  equation

3s+s =32

4s = 32

Divide by 4

4s/4 =32/4

s = 8

Sue has 8 marbles

m = 32 = 3*8 = 24

Molly has 8 marbles

The Seven Years’ War (1756-1763) was a global conflict that spanned five continents, though it was known in America as the “French and Indian War.” After years of skirmishes between England and France in North America, England officially declared war on France in 1756, setting off what Winston Churchill later called “the first world war.” While the French, British, and Spanish battled over colonies in the New World, Frederick the Great of Prussia faced off against Austria, France, Russia and Sweden. The Seven Year’s War ended with two treaties.

Answer:

She should add 18 liters of 30% sugar syrup

Step-by-step explanation:

Let the amount of sugar syrup be x

Mathematically;

30% of x liters + 20% of 12 liters = 26% of (x + 12)

So, we have

0.3x + 2.4 = 0.26x + 3.12

0.3x-0.26x = 3.12-2.4

0.04x = 0.72

x = 0.72/0.04

x = 18

Work Shown:

x = preimage length = 12

y = image length = 4

z = scale factor

z = y/x

z = 4/12

z = (1*4)/(3*4)

z = 1/3

The scale factor is 1/3.

This means the image is 1/3 of the length of the preimage.
