Answer:
x = 1 or 2
Step-by-step explanation:
[tex] \sqrt{2 - x} = x - 2[/tex]
Squaring both the sides ,
[tex] = > { (\sqrt{2 - x}) }^{2} = {(x - 2)}^{2} [/tex]
[tex] = >2 - x = {x}^{2} - 4x + 4[/tex]
Adding like terms ,
[tex] = > {x}^{2} - 4x + x + 4 - 2 = 0[/tex]
[tex] = > {x}^{2} - 3x + 2 = 0[/tex]
Factorising the eqn. ,
[tex] = > {x}^{2} - x - 2x + 2 = 0[/tex]
[tex] = > x(x - 1) - 2(x - 1) = 0[/tex]
[tex] = > (x - 1)(x - 2) = 0[/tex]
Here x will have 2 values .
1) [tex]x - 1 = 0[/tex]
[tex] = > x = 1[/tex]
2) [tex]x - 2 = 0[/tex]
[tex] = > x = 2[/tex]

Answer with work please I need help???
Don’t mind the work in the box I didn’t have space for it on the other question.
Step-by-step explanation:
Applying Pythagoras theorem ,
[tex]{24}^{2} = {11}^{2} + {x}^{2} \\ 576 = {121} + {x}^{2} \\ {x}^{2} = 576 - 121 \\ {x}^{2} = 455 \\ x = \sqrt{455} \\ x = 21.33[/tex]

A model ship is built to a scale of 1 cm : 5m. The length of the model is 25 cm. What is the length of the actual ship?
Answer:
The length of the actual ship is 125 meters.
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling for example, when representing geographic locations on a map.
A model ship is built to a scale of 1 cm: 5 m. This means that each centimeter of the model represents an actual length of 5 m.
The length of the model is 25 cm, thus the real ship has a length of 25*5 = 125 m.
The length of the actual ship is 125 meters.
The original triangle shown in the
diagram above is reflected across the
y-axis. In which quadrant is the image
of the triangle located?
Answer:
i think (2,2)
Step-by-step explanation:
Answer: Quadrant #2 The one of the upper left corner
Step-by-step explanation:
If you reflect across the y-axis the x coordinate's become negative but the y-coordinates stay positive
so if you reflect it over the y-axis the coordinate's would be
(-4, 1), (-2, 2), (-3, 4)

In the ellipse shown below, the red line segment is called the
A. major axis
B. diameter
C. minor axis
D. radius
Answer:
A. Major Axis
Step-by-step explanation:
Red line shows the Major axis of the ellipse drawn.
What is Conic Section?A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane.
An ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.
An ellipse uses two axis, major and minor.
Major axis is the larger one and minor axis is smaller.
The minor axis of an ellipse is the line that contains the shorter of the two line segments about which the ellipse is symmetrical
Now we come to the question.
Here extreme points of the red line are on the ellipse are more distant than the extreme points of the axis perpendicular to the red line.
Therefore, red line shows the Major axis of the ellipse drawn.

Brian invests £4000 into his bank account.
He receives 7% per year compound interest.
How many years will it take for Brian to have more than £8000?
Answer:
10.24 years
Step-by-step explanation:
The computation of the time period is as follows:
As we know that
Amount = Principal × (1 + rate of interest)^time period
£8000 = £4000 × (1 + 0.07)^time period
£8,000 ÷ £4,000 = 1.07^time period
2 = 1.07^time period
Now apply the log to the both sides
log 2 ÷ log 1.07 = time period
= 10.24 years

Answer:
Begin by finding the area of the square, 24x22. This would equal 528. Then, we need to find the area of each circle using the area formula, [tex]\pi[/tex][tex]r^{2}[/tex]. We can plug in the numbers to get [tex]\pi[/tex][tex]3^{2}[/tex]. Multiply 3x3 to get 9[tex]\pi[/tex]. Because there are 4 circular burners, we need to multiply 9[tex]\pi[/tex] by 4 to get 36[tex]\pi[/tex] or 113.04. Now, we can subtract 528 with 113.04 to result with 414.96 or 415, when rounded. So, the answer would be 415 [tex]in.^{2}[/tex]
