PLEASE ANSWER THIS QUESTION RIGHT.What piece of information does c identify in the following equation?
y=ax2+bx+c

a) To evaluate loga 15, we can use the property of logarithms that states logab = loga + logb. Since 15 = 3 * 5, we can use this property to find that loga 15 = loga 3 + loga 5. Since loga 3 = 0.56 and loga 5 = 0.83, we can add these values to find that loga 15 = 0.56 + 0.83 = 1.39.

The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to express enormous numbers is this manner.

Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms may also be represented as multiplication and division of logarithms.

b) To evaluate loga(2/5), we can use the property of logarithms that states log(a/b) = loga - logb. Since 2/5 = 2*(1/5) we can use this property to find that loga(2/5) = loga2 - loga(1/5). Since loga2 = 0.36 and loga(1/5) = -loga5, we can subtract these values to find that loga(2/5) = 0.36 - 0.83 = -0.47

c) To evaluate loga (8a^4), we can use the property of logarithms that states log (a^n) = nloga. We get, loga (8a^4)=loga 8 + log (a^4)

=> loga 8 + loga (a^4)

=>3loga 2 + 4 loga a

=>3loga 2 + 4

=>3 * 0.36 + 4

=5.08

Therefore , the solution of the given problem of expression comes out to be 4x² +1 cannot equal 0 and thus (4x²≥0+1) has no Real factors.

Verifying an algebraic expression requires substituting a number for each variable and performing arithmetic operations. Given that 6 + 6 equals 12, the answer variable in the example above is equivalent to 6. If we are aware of the values of the variables, we can substitute those values for the original ones, which will allow us to evaluate the expression.

Here,

It is important to note that now the ratio of a coefficient of the terms 

The coefficient ratio of the words

8x³ and 2x is 8:2 = 4:1, and the coefficient ratio of the phrases 12x² and 3 is 12:3 = 4:1.

This suggests that we should categorize the original statement as follows: 

This suggests that we should combine the original expression, which is written as

=> (8x³+2x)(12x²+3)=2x(4x²+1))3(4x²+1),

before determining the common component (4x2+1)=(2x³)(4x2+1).

The fact that 4x²≥0 for x ∈ R means that

Use the two given angle measures (Y and Z) to find angle X.

X+Y+Z = 180

X+141+25 = 180

X+166 = 180

X = 180-166

X = 14

Angle X is 14 degrees.

The polynomial's zeros must be located using a method of your choice, and the linear expressions that produce those zeros must then be combined in order to describe the polynomial as a product of linear factors.

The term "triple zero" or "zero with multiplicity 3" is used to describe this. The power p governs the behaviour close to the x-intercept if a polynomial has a factor of the type (xh)p. A zero of multiplicity p is defined as x=h. The x-axis will be touched at zeros with even multiplicities on a polynomial function's graph.

A real number is multiplied by an imaginary unit, I whose feature i2 = 1 defines it as an imaginary number. Bi is an imaginary number, while b2 is its square. For instance, the square of the fictitious integer 5i is 25. Zero is regarded as both real and fictitious by definition.

You must first determine the polynomial's zeros using the method of your choice, and then combine the linear equations that result in those zeros. If you factor, you will arrive at the third degree polynomial, which must then be sorted through.

A z-score called a standard score gives an idea of how far from the mean a data point is. But technically it is a calculation of how many standard deviations below or above the population mean a raw score is.

A z-score can place on a normal distribution curve. Z-score ranges from -3 standard deviations up to +3 standard deviations.

A z-score is equal to 0 means that it is on the mean. A positive z-score shows the score is higher than the mean average.

You want the areas of the squares shown in each of the figures.

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides of a right triangle.

The square of the hypotenuse is 17² = 289.

The sum of the squares of the other two sides is ...

  shaded square + (14)² = 17²

  shaded square + 196 = 289

  shaded square = 289 -196 = 93 . . . . cm²

Sabcd = 93 cm².

The square of the diagonal is the sum of the squares of the sides. Each of those squares is the area of interest:

The measure of angle L is 66 degrees, which is found using the sum of the internal angle of a triangle. The length is 3.56 units.

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

Given that the measure of angle M is 24 degrees and angle K is 90 degrees.

The sum of internal angles of a triangle is 180 degrees, thus:

[tex]\angle M + \angle K + \angle L = 180\\\\24 + 90 + \angle L = 180 \\\\\angle L = 66[/tex]

The length of side LK can be found as follows:

tan 24 = LK / MK

tan 24 = LK / 8

0.44 * 8 = LK

LK = 3.56 units.

Brooke's yard is a square with a side length of 22 meters.

Perimeter is the total distance around the outside edge of a two-dimensional shape. Perimeter is a measure of the length of the boundary of a shape and is typically expressed in units of length, such as feet or meters. Calculating the perimeter of a shape can help you measure the size of a yard, garden, or other outdoor area.

Since the perimeter of the part covered in gravel is 22 meters, we can use the formula for the perimeter of a square (4s) to find the length of one side of the square. Therefore, the side length of the part covered in grass is 4s = 22, or s = 5.5 meters.

Using the formula for the area of a square (A = s²), we can calculate the area of the grass section of Brooke's yard. The area of the grass section of Brooke's yard is A = s²= 5.5²= 30.25 square meters.
