The value of x in the equation 7 x² + 196 = 0 will be ± 2 i√7.

We are given the equation as:

7 x² + 196 = 0

We need to solve the equation to find the value of x.

Subtracting 196 from both the sides, we get that:

7 x² + 196 - 196 = 0 - 196

7 x² = - 196

Now divide both the sides by 7, we get that:

7 x² / 7 = - 196 / 7

x² = - 28

Square root both the sides, we get that:

x = √ - 28

Using the properties of complex numbers, we get that:

x = ± 2 i√7

Therefore, we get that, the value of x in the equation 7 x² + 196 = 0 will be ± 2 i√7.

Answer: 60

Step-by-step explanation:

Step 1: In order to find the answer to this question we need to figure out what the total number of combinations we could make.

Step 2: To figure out the total number of combinations multiply each number. 4x5x3= 60.

Step 3 (explanation): The answer is 60, because we are finding out the total combinations for both the sweaters and pants and the shoes.

The domain for g (x) / f( x) = x + 4 will be all real numbers when f (x) = x - 4 and g (x) = x² - 16.

We are given the two functions as:

f (x) = x - 4

g (x) = x² - 16

Now, first, we need to divide g (x) by f (x).

So, we get that:

g (x) / f (x) =( x² - 16) / (x - 4)

g (x) / f(x) =( x - 4) (x + 4) / (x - 4)

g (x) / f( x) = x + 4

Now, the domain of the function will be all real numbers as it will be defined for all the real numbers.

Therefore, we get that the domain for g (x) / f( x) = x + 4 will be all real numbers when f (x) = x - 4 and g (x) = x² - 16.

When Andrew goes bowling, his scores are normally distributed with a mean of 115 and a standard deviation of 11 . Then the probability of his score being between 86 and 115 is 0.2047

Mean = μ = 115

SD = σ = 11

Let x1 be the first data point and x2 the second data point

We have to find the z-scores for both data points

x1 = 86

x2 = 106

So,

Z1 = ( x1- mean)/ SD

   = 86- 115 / 11

   = -29/11

   = -2.6363

Z2 =  ( x2-mean)/SD

    = 106 -115 /11

     = -0.8181

And We have to find area to the left of both points then their difference to find the probability.

So, Area to the left of z1 = 0.00427

Area to the left of z2 = 0.20897

Probability to score between 135 and 167 = z2-z1 =  0.20897-0.004270

                                                                                 = 0.2047

Hence,

The probability of his score being between 86 and 115is 0.2047

The statement that proves that polygon ABCD is not a rectangle is: C. Slope of AD × slope of AB ≠ -1 and slope of BC × slope of AB ≠ -1.

A rectangle is a quadrilateral that has four right angles, this means that two sides of the rectangle intersect each other perpendicularly to form right angles.

Thus, the slope of each pair of sides that intersect perpendicularly equals -1.

Therefore, for polygon ABCD to be a rectangle, we must prove that each pair of intersecting sides that meet have a a slopes that gives -1 when multiplied together. If the product of their slopes is not equal to -1, then the polygon is not a rectangle.

Conclusively, the statement that proves that polygon ABCD is not a rectangle is: C. Slope of AD × slope of AB ≠ -1 and slope of BC × slope of AB ≠ -1.

Point of discontinuity for each rational function. y= x-1 / (x+1)² is x = -1

In algebra, a discontinuous function is one that has a point at which the function is not defined, at which the left-hand limit and right-hand limit are equal but not equal to the value of the function at that point, or at which the limit of the function does not exist. Discontinuous functions may have three different sorts of discontinuities: jump, removable, and essential. The graph of a discontinuous function contains gaps.

Given the function is -

y= x-1 / (x+1)²

It can be expressed in the form of -

y = x-1 / (x+1)(x+1)

The function will be undefined if the denominator will be 0

⇒ x+1 = 0

⇒ x = -1

So we can conclude that the function will be undefined at point x = -1

The function shows a decay and the equation of the asymptote is y = 0

The equation of the function is given as

f(x) = 12(0.96)^x.

Next, we plot the graph of the function f(x) = 12(0.96)^x

See attachment for the graph of the function f(x) = 12(0.96)^x

From the attached graph, we can see that the values of the graph decreases as x increases.

This represents a function decay

To do this, we set the rate to 0

So, we have

y = 12 * 0

Evaluate

y = 0

Hence, the equation of the asymptote is y = 0
