The solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62

Given the following function below:

f(x) = x^2 - 2
g(x) = x - 1

Since f(x) = g(x), hence;

x^2 - 2 = x - 1
x^2 - x - 1 = 0

Factorize to have:

x = 1/2 +√5/2  or x= 1/2 - √5/2

x = 1.62 or -0.62

Hence the solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62

Answer:

x = 28

Step-by-step explanation:

Supplementary angles mean that both angles are equal to 180. So, the equation becomes 3x + 96 = 180. Solving for x, we get 28.

Answer:

The value of x is 28

Step-by-step explanation:

Given :

Now,

Supplementary angles are a pair of angles that make sum of 180° .

Therefore, The sum of given angles will be equal to 180°.

i.e. one angle + other angle = 180°

Substituting the values of angles , we get..

[tex]⇢3x + 96 = 180[/tex]

[tex]⇢3x = 180 - 96[/tex]

[tex]⇢3x = 84[/tex]

x = 23 y =67

Step-by-step explanation:

Since a rectangle is made up of 4 right angles you can solve y with the following equation:[tex]23 + y =90[/tex]

Then to solve for x, since x, y and the right angle makes up a triangle and a triangle has 180 degrees. You can use the following equation to solve for x:

  (d)  parabola

Step-by-step explanation:

The attached diagram shows some of the curves that result from a plane intersecting one nap of a double-napped cone.

__

When the plane is parallel to the generator, a parabola is the curve of intersection. When the plane intersects both naps of the cone, the resulting set of curves is a hyperbola (not shown here).

[tex]-4x^2+16 & =0\\\\\implies -4(x^2-4) & =0 \\\\\implies x^2-4 =0\\ \\\implies x^2-2^2 =0\\\\\implies (x+2)(x-2)=0\\\\\implies x=2,~~x = -2[/tex]

Answer:

x=15

Step-by-step explanation:

A line is 180 degrees

We know that 8x+19=139

8x+19=139

subtract 19 from both sides to isolate x

8x=120

divide both sides by 8

8x/8=120/8

x=15

Answer:

Katie had the highest mean score.

Step-by-step explanation:

Katie had the highest mean score because her mean score was 81.4, and Annie's highest mean score was 72.4.

Answer: Katie

Step-by-step explanation: In six of out 7 times Katie had higher marks.

Annie mean is 72.42

Katie's mean is 81.42

The numbers given below that fall within the mean absolute deviation of the data are: C. 12,990, D. 12,705, E. 12720.

The mean absolute deviation is simply the average of the distance of each of the data points there are in a data distribution.

The difference of each data point from the mean is most likely within the same range with the mean absolute vallue.

If we subtract 12,990, 12,705, and 12720 from the mean of the data, 12,367, we would get a figure close to the mean absolute deviation, 350.

So the numbers that are within the mean absolute deviation are, C. 12,990, D. 12,705, E. 12720.

Answer:

C. 81 because 9 going to make 81 an perfect square.

Answer:

1. Given the slope is 2, the equation now looks like y = 2x +b Given P (−1,4) we can solve for the b variable by substituting the x and y cordinates. 4 = 2 ⋅ (− 1) + b 4 = − 2 + b b = 6 Therefore the equation that has the slope of 2 and passes through the point (− 1,4) is y = 2x + 9 so it is d

2. i you can do that.

3. The equation for the slope of a line and the points also called point slope form of equation of a straight line is given by: y − y1 = m (x − x1) Whereas the slope-intercept form the equation of the line is given by: y = mx + b. Where b is the y-intercept.

4.In the formula,y = the y-coordinate of any point on the line,m = slope,x = the x-coordinate of any point on the line,and b = ...

Plug the slope and y-intercept into the formula. Remember,the slope is equal to the rise over the run.

Answer:

Expression equivalent to (k + k)(4) is 28.

Step-by-step explanation:

Given:

k(x) = 5x - 6

We need to find an expression equivalent to (k + k)(4)

First, we find,

(k + k)(x) = k(x) + k(x)

            = ( 5x - 6 ) + ( 5x - 6 )

            = 5x - 6 + 5x - 6

            = 5x + 5x - 6 - 6

            = 10x - 12

Now, (k + k)(4) = 10(4) - 12 = 40 - 12 = 28

Therefore, the Expression equivalent to (k + k)(4) is 28.

Considering the vertex, the quadratic equation that models the path of the golf ball is given by:

y = -0.0011875(x - 400)² + 190

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In this problem, the vertex is at the maximum height of the parabola, given by (400, 190), hence h = 400, k = 190, and:

y = a(x - 400)² + 190

It starts at the origin, that is, when x = 0, y = 0, hence:

0 = 400²a + 190

a = -190/400²

a = -0.0011875.

Hence, the equation is:

y = -0.0011875(x - 400)² + 190
