1) Solve quadratic equations by factoring.
2x^2 + 5x - 12 = 0

Answer:

The answer is C

Step-by-step explanation:

The nine from the price of Ford is in the tenths place and from Nissan is 10 times the value which 9 will be in the hundreds place.

a) The percentage is 73%.

b) The ratio is 73:27

d) The decimal form is 0.73

e) The fraction is 73/100

The percentage of the model that is shaded is given by:

P = 100%*(shaded squares)/(total number of squares)

There are 100 squares in total, of these 73 are shaded, then the percentage is:

P = 100%*(73)/100 = 73%

b) The ratio is "shaded squares to non shaded squares"

There are 73 shaded squares and 27 non-shaded ones, then the ratio is 73:27

c) To get the equivalent decimal to a percentage, just divide it by 100%.

p = 73%/100%  =0.73

d) The equivalent fraction is the fraction we wrote on the first step, it is:

fraction = 73/100

The union of two subspaces of V is a subspace of V if and only if one of the subspaces of v is contained in the other

Let \($V_1, V_2$\) be the two subspaces of V. Suppose \($V_1 \cup V_2$\) is a subspace of V.

Then if \($x_1 \in V_1$\) and \($x_2 \in V_2$\) then we must have \($x_1 \in V_1 \cup V_2$\) and\($x_2 \in V_1 \cup V_2$\) so that we must have \($x_1+x_2 \in V_1 \cup V_2$\).

If and only if one of the subspaces is contained in the other, the union of the two subspaces is a subspace.

But this by definition means \($x_1+x_2 \in V_1$\) or \($x_1+x_2 \in V_2$\). Either way, by the existence of additive inverses and the closure properties for the subspaces we have:

\(\left(x_1+x_2\right)+\left(-x_1\right) \in V_1\)

Or

\(\left(x_1+x_2\right)+\left(-x_2\right) \in V_2\)

By the associative/commutative properties, we have:

\(x_2 \in V_1 \text {, or, } x_2 \in V_1\)

Thus we have shown if \($x_1 \in V_1$\) and \($x_2 \in V_2$\) then \($x_1 \in V_2$\) or \($x_2 \in V_1$\). If \($x_1 \in V_2$\) for all \($x_1 \in V_1$\) then we have \($V_1 \subseteq V_2$\). If \($x_2 \in V_1$\) for all \($x_2 \in V_2$\) then \($V_2 \subseteq V_1$\). In either case, we see one subspace is a subset of the other.

x must be any number greater than 25/6

Step-by-step explanation:

10/12 < x/5

Simplfy the left:                     5/6  <   x/5

Multiply both sides by 5:      25/6 < x

Answer:

x = -8 and x= 7

Step-by-step explanation:

recall that for a rational expression, the vertical asymptotes occur at x-values that causes the expression to become undefined. These occur when the denominator becomes zero.

Hence the asymptototes will occur in x-locations where the denominator , i.e

(x+8)(x-7) = 0

solving this, we get

(x+8) = 0 ----> x = -8

or

(x-7) = 0 ------> x = 7

hence the asymptotes occur x = -8 and x= 7

Answer:

x = -8 and x = 7.

Step-by-step explanation:

The vertical asymptotes are lines that the function will never touch.

Since no number can be divided by 0, the function will not touch points where the denominator of the function is equal to 0.

\(\frac{x - 6}{(x + 8)(x - 7)}\), so the vertical asymptotes will be where (x + 8) = 0 and (x - 7) = 0.

x + 8 = 0

x = -8

x - 7 = 0

x = 7

The vertical asymptotes are at x = -8 and x = 7.

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

The likelihood that a population parameter will be less than a given value when the null hypothesis is true is expressed as the p-value, also known as a probability value or a measure of significance, for a particular statistical model.

It takes time of near about 35 year.

Given that,

Storage capability of computers has been doubling every 5 years

The date of 1st computer made = 1980

computer could store 5 megabytes,

Now,

We can use the following calculation to determine how long it took computers to store 100 megabytes:

Therefore,

Log₂ (final amount / beginning amount)

=  Log₂ (100 / 0.5)

= log₂ (200)

= 7.64 is the number of doublings.

If each doubling takes five years, then it would take computers just over seven doublings or almost 35 years to store 100 megabytes.

One of the transformations undergone by Triangle 1 is a rotation, which involves turning the triangle around a fixed point while preserving its shape and size.

A rotation is a transformation that turns an object around a fixed point, known as the center of rotation. In the given results, if the triangle appears in a different orientation but retains its shape and size, it indicates a rotation.

During a rotation, each point of the triangle is moved along a circular path around the center of rotation. The distance from the center of rotation remains constant, and the angle between any two corresponding points on the original and rotated triangles is preserved. The direction of rotation can be clockwise or counterclockwise, depending on the given results.

To describe a rotation, we need to specify the angle of rotation and the direction. For example, "Triangle 1 underwent a counterclockwise rotation of 90 degrees" would indicate that the triangle was rotated by 90 degrees in the counterclockwise direction.

The specific rotation can be described by stating the angle of rotation and the direction.

The first nine is 100 times greater than the other 9 because the first nine is in the ones place and the second 9 is in the hundredths place.

Among the mean, mode, and median, the unique one is the b. mode.

The mode is the data value that occurs many times more than other data values.

Unlike the mean that shows the average value of all the data values, the mode occurs more.  While we compute the mean by dividing the total data value by the number of data items, the mode is not computed but found as the most frequent data value.

Similarly, the median can be computed when two values occur as the middle values.

Thus, among the three measures of central tendency, the mean, the median, and the mode, the mode is the most unique since it is not computed.
