Answer:

The person will have P-4 paintings left      

Step-by-step explanation:

We are told that the total number of painters who entered into the painting donation agreement to the local museum is 12 painters

and they all agreed to donate 48 paintings equally

so each painter will donate

48/12= 4paintings

Since this person already had P paintings in his art collection

his painting will reduce by the 4 paintings he denoted to the local museum\

hence he will have

P-4 paintings remaining

x= 1 + 5 √2

x= 1 - 5 √2

The values of x in the expression are x = 1 + √51 and x = 1 – √51.

We have,

Expanding the left side of the equation, we get:

(x – 1)2 = x2 – 2x + 1

So, we have:

x2 – 2x + 1 = 50

Subtracting 50 from both sides, we get:

x2 – 2x – 49 = 0

Now, we can use the quadratic formula to solve for x:

x = [2 ± √(22 – 4(1)(–49))] / (2)

x = [2 ± √(204)] / (2)

x = [2 ± 2√51] / (2)

x = 1 ± √51

Therefore,

The values of x are x = 1 + √51 and x = 1 – √51.

Answer:

Step-by-step explanation:

Answer:

5 family members went swimming with the dolphins.

Step-by-step explanation:

From the information given, you can say that the total cost for the family to swim with dolphins is equal to the flat fee for the family to rent wet suits plus the extra cost per person for the number of family members:

1024.99=75+189.99x, where x is the number of family members

Now, you can solve for x:

1024.99-75=189.99x

949.99=189.99x

x=949.99/189.99

x=5

According to this, the answer is that 5 family members went swimming with the dolphins.

Answer:

The answer is

[tex] - \frac{4}{3} \\ [/tex]

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,7) and (-1,3)

We have

[tex]m = \frac{3 - 7}{ - 1 - - 4} = \frac{ - 4}{ - 1 + 4} = - \frac{4}{3} \\ [/tex]

We have the final answer as

[tex] - \frac{4}{3} \\ [/tex]

Answer:

(1) 1.2 cm

(2) 200 cm by 250 cm

Step-by-step explanation:

The scaled dimention = (Actual dimension) x (scale factor) ...(i)

The given scale factor =1/50

(1) The actual width of the bedroom door= 60 cm.

So, from equation (i),

the width of the door on the scale drawing= 60 x (1/50)=1.2 cm

(2) The scaled dimension of the bed is 4 cm by 5cm.

So, the scaled width of the bed = 4cm and

the scaled length of the bed = 5cm.

So, from equation (i),

4 cm = (Actual width) x (1/50)

So, Actual width = 50 x 4 cm = 200 cm.

And, 4 cm = (Actual length) x (1/50)

So, Actual width = 50 x 5 cm = 250 cm.

=Hence, the actual measurements of his bed is 200 cm by 250 cm.

Answer: Place the compass point at A i think

Step-by-step explanation: if a and b go toghter than its not c so i would be ertier since b is closer it is not b so the answer is a i think

B) Place the compass point at B

Answer:The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

f(3) = 8

Step-by-step explanation:

f(x) = 3x - 1

f(3) = 3(3) - 1

f(3) = 9 - 1

f(3) = 8

f(x) = (x-7)(x+7)(x+4)

= (x^2 - 49)(x+4)

Answer:

Independent variable: distance

Dependent variable: number of letters recognized on an eye chart

Step-by-step explanation:

Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.

Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.

Since the hypothesis is that the distance affects the number of letters recognized,

the distance causes a change in the number of letters recognized not the other way around.

Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

Answer:

B. 55

Step-by-step explanation:

The angle measurements on the top are the same as the bottom, so we know  the angle next to (x+70) is 55. You then subtract 55 from 180 and you are left with 125. Then you have to subtract 70 to find x, which gives you 55. Therefore, x=55

Answer:

Step-by-step explanation:

The general expansion of (a + b)² is

(a + b)² = a² + 2ab + b²

Applying this to the following expansions

(1)

(x + 2)² = x² + 2(2x) + 2² = x² + 4x + 4 ← missing term is x²

(2)

(2x - 3)² = (2x)² + 2(2x)(- 3) + 3² = 4x² - 12x +9 ← missing term is - 12x

(3)

(3x + 4)² = (3x)² + 2(3x)(4) + 4² = 9x² + 24x + 16 ← missing term is 16

(4)

(x - y)² = x² + 2(x)(- y) + y² = x² - 2xy + y² ← missing term is x²

(5)

(2x + 3y)² = (2x)² + 2(2x)(3y) + (3y)² = 4x² + 12xy + 9y² ← missing term is + 12xy

Answer:

1) The coordinates of P' is (7, -5)

2) The coordinates of P' is (-5, -7)

3) The coordinates of P' is (-7, 5)

4) The coordinates of A' is (7, 5);

5) Q' is (-7, 5)

6) The coordinates of L is (-6, 7)

7) The coordinates of A''' is (1, 10)

Step-by-step explanation:

1) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)

Therefore, given that the preimage P is (5, 7), we have the image, P', after 90 degrees clockwise rotation is (7, -5);

2) The coordinates of a preimage (x, y) after 180-degrees clockwise rotation gives the image (-x, -y)

Given that the preimage, point P, has coordinates (5, 7) the image, P', after 180-degrees rotation becomes (-5, -7)

3) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)

∴ The coordinates of the preimage, P = (5, 7), after 270-degrees clockwise rotation gives the image, P', = (-7, 5)

4) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)

Therefore, given that the preimage A is (-5, 7), we have the image, A', after 90 degrees clockwise rotation is (7, 5);

5) The coordinate of the preimage, point Q is (5, 7) after 270-degrees clockwise rotation gives the image, Q', = (-7, 5)

6) The image of a preimage, (x, y) after 180-degrees rotation is (-x, -y). Therefore, given that the image of the preimage L, after 180 degrees rotation is L' (6, -7), we have the coordinates of L is (-6, 7)

7) The coordinates of the preimage, A = (-5, -8)

a) A is translated 6 units to the right and 2 units to give;

A'(-5 + 6, -8 - 2) = A'*1, -10)

b) (x, y) is reflected across the line y = -x, to give (-y, -x)

∴ A'(1, -10) is reflected across the line y = -x, A''(10, -1)

c) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)

∴ The coordinates of the preimage, A''(10, -1), after 270-degrees clockwise rotation gives the image, A'''(1, 10).
