The solution of the Jordan's system is 3/2 and -1.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 2x² + 3..............(1)

y – x = 6

y= 6 +x ..............(2)

Put the value from (2) in equation (1) we get

y = 2x² + 3

6+ x  = 2x² + 3

2x² + 3 -6 -x = 0

2x² - x - 3 = 0

2x² -3x + 2x -3= 0

x( 2x-3) +1 (2x-3)= 0

(2x- 3)(x+1)= 0

x= 3/2, -1.

Hence, the value is 3/2, -1.

Answer:

13

Step-by-step explanation:

cos 13 x 2 = 26

13 is a factor that is more than 4 and less then 26

The factor of the number 26 that is between 4 and 26 is 13. Factors are the numbers that can divide into a number without leaving a remainder. In this case, the factors of 26 are 1, 2, 13, and 26.

In mathematics, a factor of a number is a number that divides into another number without leaving a remainder. In the case of the number 26, its factors include 1, 2, 13, and 26. The factor of 26 that is between 4 and 26 is 13.

To find this, you can go through the factors of 26 one by one. The factors are found by dividing 26 by all the numbers up to 26, and the numbers that give a remainder of 0 are the factors. In this case, 1, 2, 13, and 26 divide evenly into 26, and so are the factors of 26. Of these, only 13 lies between 4 and 26.

The trigonometric function equation obtained for the graph is y = 4 sec (πx) - 2.

What is trigonometric function?

Simply put, trigonometric functions also referred to as circular functions are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle.

The upper waver have a value of y = 2 and the lower waves have a value of  y = -6.

Add the points and divide by 2 -

[2 + (-6)] / 2

(2 - 6) / 2

-4 / 2

-2

Therefore, the midline is y = -2.

The vertical asymptotes are drawn and they intersect the midline at certain points.

Then the sinusoidal function is drawn using the intersection point.

There is one period of sinusoidal function that is starting from x = 0 and goes upto x = 2.

This pattern tells that the function is of cosine.

Then the graph will be of trigonometric function secant .

The value of C = -2 , A = 4, D = 0

Here C is the midline value, A is the points above and below the midline, D is the horizontal shift and 2π/B is the period.

Now, 2π/B = 2

2B = 2π

B = π

Now, use the formula -

y = A cos (B(x - D)) + C

y = 4 cos (π(x - 0)) - 2

y = 4 cos (πx) - 2

y = 4 sec (πx) - 2

Now plot the graph for the obtained function.

The graph is same as given in the question.

Therefore, the function is y = 4 sec (πx) - 2.

The expected phenotypes for the offspring is All tall.

Mendel came to the conclusion that some features predominated over other inherited traits when he noticed that a heterozygote offspring might exhibit the same phenotype as the parent homozygote. However, the connection between genotype and phenotype is rarely as straightforward as Mendel's descriptions of dominant and recessive patterns.

Given:

One is short and one is tall, Tall is dominant.

When two plants that are tall and short are crossed. They would all produce tall plants as a result, T.

The first crossing produced these children.

As a result of their parents' TT and SS genes, they all now have TS genes.

There will be some towering and some short off springs when these off springs are crossed. TS and TS will cross at this location. Given that they are all genetically tall and short.

So, The ratio of tall to short children they would have according to Mendel is 3:1.

Answer: 42

Step-by-step explanation: 165 x .25 = 42

Answer:

42

Step-by-step explanation:

If Naomi has 168 apps, then 100% is equal to 168 (since that's all her apps)

If 25% of these apps are games, then 25% is equal to x

If we multiply the number of total apps by the percentage of games, we'll find the total number of game apps

First change the percentage into a decimal:

25% = 0.25

Then multiply:

168 * 0.25 = x

Simplify:

x = 42

Another way you can do this is by realizing that 0.25 is equal to 1/4. If 168 is multiplied by 1/4, then that means the resulting equation is:

168/4 = x

x results in the same answer as the previous way:

x = 42

A translation in mathematics does not turn a shape; instead, it moves it left, right, up, or down. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have only changed their direction or directions. The shape just shifts from one place to another, therefore there is no change in the shape.

The degrees of freedom for this test are (3 - 1) = 2. With a 5% significance level and 2 degrees of freedom, the critical value for a chi-squared distribution is 5.991.

To determine whether customer preferences have changed, the analyst can conduct a hypothesis test. The null hypothesis is that customer preferences have not changed, and the alternative hypothesis is that customer preferences have changed.

The test statistic used to test this hypothesis is a chi-squared statistic. The formula for the chi-squared statistic is:

X² = ∑((O - E)² / E)

where O is the observed frequency, and E is the expected frequency based on the null hypothesis.

The expected frequency for Apple is 200 * 0.45 = 90, for Samsung is 200 * 0.40 = 80, and for others is 200 * 0.15 = 30.

Calculating the chi-squared statistic:

X² = ∑((102 - 90)² / 90) + ((82 - 80)² / 80) + ((16 - 30)² / 30) = (12² / 90) + (2² / 80) + (14² / 30) = 144 / 90 + 4 / 80 + 196 / 30 = 2.56 + 0.05 + 6.53 = 9.14

The degrees of freedom for this test are (3 - 1) = 2. With a 5% significance level and 2 degrees of freedom, the critical value for a chi-squared distribution is 5.991.

Since 9.14 > 5.991, the analyst can reject the null hypothesis and conclude that customer preferences have changed from their levels before the advertising campaigns were launched.

Answer: All angles of the regular polygon in the image are 90 degrees

Step-by-step explanation: Hello!

All interior angles of a four-sided polygon add up to 360 degrees.  Since this is a square, all interior angles are congruent.  There are four interior angles that are congruent and they all add up to 360 degrees.  This can be represented by the equation:

s (side) x 4 = 360

Divide each side by 4 by the division property of equality.

s x 4/4 = 360/4

s = 90 degrees.

Each angle of the polygon is 90 degrees.

"The common property for all [] four-sided shapes is the sum of interior angles is always equal to 360 degrees. For a regular quadrilateral such as square, each interior angle will be equal to: 360/4 = 90 degrees."

Answer:

The measure of each interior angle of the regular polygon pictured below is 151.7°. This can be calculated using the formula 180n - 360, where n is the number of sides of the polygon. In this case, n = 8, so the measure of each interior angle is 180(8) - 360 = 151.7°.

Step-by-step explanation:

To solve this equation, we need to use the logarithmic properties. First, we can use the property loga(bx) = x loga(b) to rewrite the equation:

log3(5) + log3(x) = log3(35)

This can be rewritten as:

log3(5x) = log3(35)

Using the property loga(b) = c, we can re-write the equation as:

x = 35/5

Now, we can calculate the value of 35/5:

35/5 = 7

Therefore, the solution to the equation is x = 7.

The equation of line is y = -50x + 150

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Points:(1, 100) (2, 50) (4, 25), (5, 20)

so, the slope is

= (50-100)/ (2-1)

= -50 /1

= -50

using slope intercept form

y - 100 = m (x- 1)

y- 100 = -50(x-1)

y- 100 = -50x + 50

y = -50x + 50 + 100
