An extraneous solution is the root of a transformed equation that isn't the root of the original equation.

Your information is incomplete. Therefore, an overview will be given. It should be noted that an extraneous solution simply means a solution that is gotten from the solving of a problem but isn't a valid solution to the problem.

In order to find whether a solution is extraneous, you'll bed to plug it back into the equation and see if it works.

Answer:

Step-by-step explanation:

f(x) = 4-x

g(x) = h[tex]x^{2}[/tex]+k

g(f(x)) = 2[tex]x^{2}[/tex]-16x+26

so put  f(x)  in g(x)

h[tex](4-x)^{2}[/tex]+k

h((4-x)(4-x) + k

h([tex]x^{2}[/tex]-8x+16)+k

if h = 2 , then

2[tex]x^{2}[/tex]-16x+32 + k

and we want 26  instead of 32 so subtract 6 so K = (-6)

2[tex]x^{2}[/tex]-16x+32 + (-6)

2[tex]x^{2}[/tex]-16x+32 - 6

2[tex]x^{2}[/tex]-16x+26

h=2

k=(-6)

Based on the calculations, the total distance of Mara's run is equal to: C. 12 km.

In order to determine the total distance of Mara's run, we would solve for the length of the hypotenuse by applying Pythagorean's theorem and then add it to the other distances.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

Substituting the given parameters into the formula, we have;

c² = 3² + 4²

c² = 9 + 16

c = √25

c = 5 km.

Now, we can determine the total distance of Mara's run:

Total distance = 3 + 4 + 5

Total distance = 12 km.

The amount of profit Gavin made in selling the water bottles at the base ball game is $65.

He bought 75 bottle water for a total of $25.

He sales all of the  bottles for $1.20 each.

Therefore,

profit = selling price - cost price

Hence,

cost price = $25

selling price = 1.20(75) = $90

Finally,

profit = 90 - 25 = $65

The expression of Volume in cubic meter  [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)

The correct option is (1)

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

Volume of rectangular pyramid= [tex]\frac{1}{3}[/tex] * base area* height

                                                   = [tex]\frac{1}{3}[/tex] * 6*8*(10-4)

                                                   =[tex]\frac{1}{3}[/tex] * 6*8*6

Volume of cuboid= l*b*h

                              = 4*6*8

So, Volume   =[tex]\frac{1}{3}[/tex] * 6*8*6 + 4*6*8

                     = [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)

formula? sorry if im wrong

Step-by-step explanation:

If the mass of the water is 260 grams. Then the weight of the water and the cup will be 460 grams.

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

mass = density × volume

    m = ρv

My coffee mug weighs 200 g and holds 260 cm³.

If I fill it with water. Then the total weight will be

The density of the water will be 1 g/cm³.

Then the total weight will be

w = 200 + 1 x 260

w = 200 + 260

w = 460 g

Step-by-step explanation:

Given expression: (square root 5) - (3 square root 5)

Therefore, the combined radical of (square root 5) - (3 square root 5) is [tex]-4\sqrt{5}[/tex]

The value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle shown in the picture.

The angle APE = 90 degree (from the figure)

25x + 15 = 90

25x = 75

x = 3

The measure of arc CDE = (20x + 4) + (33x - 9) = 53x -5

= 53(3) -5

= 154 degree

Thus, the value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.

Step-by-step explanation:

by the way, you are completely and exactly right at 6.

Q is the inscribed angle of the (inner) arc angle TR.

and as such it is half of that arc angle TR.

S is now on the same side of the circle center as the segment TR. so, we have to flip the situation around :

S is half of the outside arc angle between T and R.

as the sum of the inner and outside arc angles are 360° (the full circle), the sum of half of their values is then

360/2 = 180°

so, yes,

x + 2 + 9x - 7 = 180

10x - 5 = 180

10x = 185

x = 18.5

Q = x + 2 = 18.5 + 2 = 20.5°

S = 9x - 7 = 9×18.5 - 7 = 166.5 - 7 = 159.5°
