(x - 4)(3x + 2) is an expression that is equivalent to 3x² - 10x - 8.

A quadratic equation is one in which the variable is squared in just one term and not in any other term where the variable is raised to a power greater than 2.

Lets take the quadratic equation:  3x² - 10x - 8

First we will multiply 3[tex]x^{2}[/tex] and -8, therefore we will get -24[tex]x^{2}[/tex].

Then we will break -10 x in a way that its terms give a product of -24[tex]x^{2}[/tex] when multiplied, i.e.,  -10x = 12x - 2x

Thus, 3x² - 10x - 8 = 3x² + 12x - 2x - 8

                              = 3x(x + 4) -2(x + 4)

                              = (3x - 2)(x + 4)

Hence, (3x - 2)(x + 4) is the correct answer.

The measure of angle 2 is 23 degrees.

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle. It is not necessary for the angle to be in Euclidean space if it lies in the plane. Angles are referred to as dihedral angles if they are created by the intersection of two planes in a space other than Euclidean.

Let the measure of angle 2 be x.

Then the measure of angle 1 = x + 17

The measure of angle ABD = 63.

From the figure we can observe that:

ABD = angle 1 + angle 2

Substitute the values:

63 = x + 17 + x

63 - 17 = 2x

46 = 2x

x = 23

Hence, the measure of angle 2 is 23 degrees.

Step-by-step explanation:

The reason that best supports Statement 4 in the

given proof is option A. Addition Property of Equality

The statement 4, "4x + 18 = 78," is an equation that is being derived from the previous statements in the proof. The left side of the equation (4x + 18) represents the value of m/X, which was given as 4x + 18 in statement 2.

The right side of the equation (78) represents the value of m2Y, which was given as 78° in statement 3.

Therefore, statement 4 is derived by substituting the known values of m/X and m2Y into the equation m/X = m2Y, which was given as statement 1.

The reason for this substitution is the Addition Property of Equality, which states that if you add the same value to both sides of an equation, the two sides remain equal.

In this case, the same value (4x + 18) is being added to both sides of the equation m/X = m2Y, resulting in the equation 4x + 18 = 78.

The area of the rectangle is 36.83 m² and perimeter is 25.42 m

A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°). The opposite sides of a rectangle are equal and parallel.

Given that, you design a tree house using a coordinate plane in which the coordinates are measured in meters. The vertices of the rectangular floor are (0,5), (4,3), (4,13) and (8,11).

We know that, distance between two points is = [tex]\sqrt{(x_{2}-x_{1} )^2+(y_{2} -y_1)^2}[/tex]

Distance between (0,5) and (4,3) = [tex]\sqrt{(4-0)^2+(3-5)^2}[/tex]

= [tex]\sqrt{16+4}[/tex]

= 4.47 m

Distance between (4, 3) and (8, 11) = [tex]\sqrt{(8-4)^2+(11-3)^2}[/tex]

= [tex]\sqrt{4+64}[/tex]

= 8.24 m

Therefore, in reference to the rectangle given, the length = 8.24 m and width = 4.47 m

Area of the rectangle = 4.47 x 8.24 = 36.83 m²

Perimeter = 2(4.47+8.24) = 2 x 12.71 = 25.42 m

Hence, the area of the rectangle is 36.83 m² and perimeter is 25.42 m

The ratio of blue marbles to the total number of marbles is; 3:16.

The total number of marbles in the jar is 18 red + 12 blue + 20 yellow + 14 green = 64.

So, the ratio of blue marbles to the total number of marbles can be expressed as 12:64.

This ratio can be simplified by dividing both the numerator and denominator by the greatest common factor, which in this case is 4.

So, the simplified ratio becomes 12/4 : 64/4 = 3:16.

This means for every 16 marbles in the jar, 3 of them are blue.

The simplified ratio of 3:16 can be understood as a fraction, where the numerator represents the number of blue marbles and the denominator represents the total number of marbles in the jar.

This fraction can be converted to a percentage by multiplying it with 100, which gives 18.75%.

Therefore, the ratio of blue marbles to the total number of marbles is 12:64, which simplifies to 3:16.

Answer:

a=4, b = 12

Step-by-step explanation:

This is a relatively simple question once you break it down. Make two equations based on the rectangles given:

64 = 4b + 4a

56 = 8a + 2b

64 = 4b + 4a => 64 = 4 (b+a) => 16 = b + a

isolate for a variable (any will do I just chose b)

16 - a = b

56 = 8a + 2b => 56 = 2(4a + b) => 28 = 4a + b

isolate for b then plug in equation

28 - 4a = b

16 - a = 28 - 4a

28 - 16 = -a + 4a

12 = 3a

4 = a

16 - a = b

b = 16 - 4

b = 12

There are 1257529 bacteria after 6 hours.

A. Let y be the number of bacteria after x hours.

We know that y=10,000 when x=1 and

y=3,800 when x=0.

So we can write the equation as follows:

y = 3800 * (10,000/3,800)^x

Evaluate

y = 3800 * (2.63)^x

B. To find the number of bacteria after 6 hours, we substitute x=6 into the equation above:

y = 3800 * (2.63)^6

Evaluate

y = 1257529

If we wish to accumulate $3,641 after 6 years at a 5% interest rate, then $2,717.16 must be set aside at the end of each of the 6 periods

The Amount = $3,641

Time = 6 years

Interest Rate = 5% = 0.05

Compounded at the end of each of the 6 periods.

So n = 6 × 6 = 36

Periodic interest rate;

i = r/m

i = 0.05/6

i = 0.00833

Compound Formula

A = P(1 + i)^n

3,641 = P(1 + 0.00833)^36

3,641 = P(1.00833)^36

False. The weight of a variable in a standardized predictor environment does not necessarily indicate that the variable has a higher discriminating power.

Discriminating power is determined by the correlation of a predictor variable with the outcome variable. We can calculate the correlation between a predictor variable and an outcome variable using Pearson's correlation coefficient, which is represented by the formula:

r = (NΣXY - (ΣX)(ΣY)) / √[(NΣX2 - (ΣX)2)(NΣY2 - (ΣY)2)].

In this formula, N is the sample size, ΣX is the sum of the predictor variable, ΣY is the sum of the outcome variable, ΣXY is the sum of the products of the predictor and outcome variables, and ΣX2 and ΣY2 are the sums of the squares of the predictor and outcome variables, respectively. The Pearson's correlation coefficient ranges from -1 to +1, with +1 indicating perfect positive correlation, 0 indicating no correlation, and -1 indicating perfect negative correlation. A higher correlation coefficient indicates a higher discriminating power.

Therefore, the weight of a variable in a standardized predictor environment does not indicate whether or not the variable has a higher discriminating power; this is determined by the correlation between the predictor and outcome variables.

the probability that a student scored greater than 65 is 0.2389.

The probability that a student scored greater than 65 can be calculated using the standard normal distribution and the z-score. The z-score represents the number of standard deviations a value is from the mean, and can be calculated as follows:

z = (x - mean) / standard deviation

Where x is the score of interest (65)

Mean is the average score of the students (70)

Standard deviation is the standard deviation of the scores (7).

Plugging in the values, we get

z = (65 - 70) / 7 = -0.714.

Using a standard normal distribution table, we can find the probability that a student scored greater than 65 by finding the area to the right of the z-score. The probability of a student scoring greater than 65 is approximately 0.2389, or 23.89%.

The approximate values for the definite integral of x⁶ over the interval [1, 2].

An integral is a mathematical tool used to calculate the total amount of some quantity that changes continuously over a given interval.

The Trapezoidal rule approximates the definite integral of a function by dividing the interval of integration into a number of smaller subintervals, and then using trapezoids to approximate the area under the curve.

The formula for T6 is:

T6 = (b-a) * (f(a) + f(b)) / 2,

where a and b are the limits of integration, and f(x) is the function being integrated.

However, instead of using trapezoids, the Midpoint rule uses rectangles to approximate the area under the curve.

The formula for M6 is:

M6 = (b-a) * f((a + b) / 2)

To calculate T6 and M6 for the integral (a=1)(b=2)x⁶dx, we need to use the formulas above and plug in the appropriate values for a, b, and f(x). The function f(x) is x⁶, so:

T6 = (2 - 1) x (1⁶ + 2⁶) / 2 = 1 x (1 + 64) / 2 = 32.5

M6 = (2 - 1) x (2⁶)¹/₂ = 1 x (64)¹/₂ = 8
