Answer:

Factor 3x+3

Answer:

P=2[9x-3]

Step-by-step explanation:

perimeter of rectangle =2(L+W)=2L+2W

where P=perimeter of rectangle

L=length of rectangle =3x+3

W=width of rectangle =6x-6

P=2[(3x+3)+(6x-6)]

P=2[3x+3+6x-6]

P=2[9x-3]

The measure of the smallest angle of the triangle would be = 33°

The total angle measurement of a triangle is a total of 180°.

That is ;

180° = 90 + (4x-7)° + (3x-15)°

180 = 90-7-15+4x+3x

180 = 90-22+7x

180 = 68+7x

180-68 = 7x

7x = 112

X= 112/7

X= 16

substitute X=16 into both angles (4x-7)° and (3x-15)° to know the smallest.

= 4(16)-7

= 64-7

= 57°

and;

= 3(16)-15

The simplification of the fractions gives 4 / (b - d).

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Here, a is called the numerator and b is called the denominator.

Given expression is [tex]\frac{8a + 4b}{2ab+b^2-2ad-bd}[/tex].

We have to simplify each of the numerator and denominator in the expression [tex]\frac{8a + 4b}{2ab+b^2-2ad-bd}[/tex].

Take the common factor in each of the expressions in numerator and denominator.

8a + 4b = 4(2a + b)

2ab + b² - 2ad - bd = 2ab - 2ad + b² - bd

                               = 2a(b - d) + b(b - d)

                               = (b - d) (2a + b)

[tex]\frac{8a + 4b}{2ab+b^2-2ad-bd}[/tex] = [tex]\frac{4(2a+b)}{(b-d)(2a+b)}[/tex]

                     = [tex]\frac{4}{b-d}[/tex]

Answer:

The rate at which the turtle is crawling can be found by dividing the distance traveled in miles by the time in hours.

So, the turtle can travel 3/20 of a mile in 5/6 of an hour, which means that the turtle is crawling at a rate of (3/20) / (5/6) miles per hour.

To simplify, we need to convert both the numerator and denominator to a common unit. If we multiply the numerator and denominator by 6, we get:

(3/20) * 6 / (5/6) * 6 = 3 / 5 miles per hour.

Therefore, the turtle is crawling at a rate of 3/5 miles per hour.

Answer:

a. Congruent

Step-by-step explanation:

ABCD has the same dimensions of A'B'C'D', so that means that it is congruent, even though it's in a different place on the graph.

The p-value of the test is 0.112

To determine whether the consumer group's belief is supported by the sample data, we can perform a one-sample t-test.

The null hypothesis is that the true average score improvement is equal to 50 points, while the alternative hypothesis is that it is less than 50 points.

Using the sample data, we can calculate the t-statistic as:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

t = (44 - 50) / (27 / √(31))

t = -1.24

The degrees of freedom for this test is 30 (sample size minus one).

Using a t-distribution table or calculator, we can find the p-value associated with this t-statistic and degrees of freedom, which is the probability of observing a t-statistic as extreme as -1.24 or more extreme, assuming that the null hypothesis is true.

The p-value is approximately 0.112.

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is evidence that the true average score improvement is less than 50 points.

Therefore, the consumer group's belief is supported by the sample data.

A statistic is an estimate or calculation based on a sample size of data, while a parameter is a numerical characteristic of an entire population.

A statistic is a value or set of values which are calculated from a sample of data. Statistic values are used to measure attributes of a population, such as the mean, median, or mode of a population. Statistic values are estimates and can be subject to sampling error. Parameters, on the other hand, are numerical characteristics of an entire population. Parameters are fixed values which describe the population as a whole. For example, thirty percent of all dog owners might be a statistic, as it is an estimate based on a sample of data. However, the total number of dog owners would be a parameter, as it describes the entire population of dog owners. Parameters are not subject to sampling error, and they cannot be calculated from a sample set of data.

The smallest integer a such that the intermediate value theorem guarantees that f(x) has a zero on the interval [0, a] is 2.

The intermediate value theorem states that if a function f is continuous on the closed interval [a, b] and if y is a value between f(a) and f(b), then there exists a point c in the interval [a, b] such that f(c) = y.

In this case, we want to find the smallest integer a such that f(x) has a zero on the interval [0, a]. Since f(0) = 7 and f(x) = -2x^3 + 8x^2 - 6x + 7, we need to find the smallest a such that f(a) < 0.

We can start by finding the values of x where f(x) changes sign. To do this, we can set f(x) equal to 0 and solve for x:

-2x^3 + 8x^2 - 6x + 7 = 0

This is a cubic equation and can be solved using various methods such as factoring, substitution, or the use of a numerical method. However, since we are looking for the smallest integer a, we can use an estimation method such as the Newton-Raphson method to approximate the smallest positive root of the equation.

A common initial guess for the smallest positive root of a cubic equation is x = 1. Using this as the initial guess, we can iterate using the following formula:

x_{n+1} = x_n - f(x_n)/f'(x_n)

where f'(x) is the derivative of f(x) and x_n is the nth estimate of the root.

After several iterations, the estimate for the smallest positive root of the equation can be found to be approximately 1.56. Therefore, the smallest integer a such that the intermediate value theorem guarantees that f(x) has a zero on the interval [0, a] is 2.

Answer: 15.40205

Step-by-step explanation:

The expression "cos 80° ÷ sin 10°" can be evaluated using the reciprocal identity of sine and cosine.

First, we convert 80° to its radian equivalent: 80° x (π/180°) = 4π/9 radians.

Next, we use the reciprocal identity of sine and cosine:

cos (θ) ÷ sin (θ) = cot (θ)

So,

cos 80° ÷ sin 10° = cot (10°).

The value of cot (10°) can be found using a calculator or a table of trigonometric values. The exact value is approximately 15.40205.

The Values for rectangle type wall and circle will be gallons of paint that are required to paint one side of a block wall =5.16 gallon, the gallons of sealer required to seal a floor=4.22 gallon and circumference of circle≈39 feet.

What exactly is a rectangle?

Rectangles are four-sided polygons with all internal angles equal to 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from a square in that its opposite sides are equal in length.

For example, if one side of a rectangle is 20 cm long, the opposing side is similarly 20 cm long.

A rectangle has two diagonals that intersect. Both diagonals are the same length

P = 2 (Length + Width) is the perimeter.

Rectangle Area=Length*Breadth

Now,

1. Given Length of wall=172 feet and breadth =6 feet then area=172*6=1032

square feet and The paint being used will cover 200 square ft per gallon.

so, gallons of paint that are required to paint one side of a block wall

=1032/200=5.16 gallon

2. Length=250 feet, breadth=120 feet then perimeter=2*370=740 feet

paint used to seal 175 feet floor=1 gallon

then the gallons of sealer required to seal a floor 120' x250'=740/175=4.22 gallon

A possible vector function that represents the curve of intersection of the two surfaces is r(t) = (5 cos(t), 5 sin(t), 5 cos(t) sin(t))

The cylinder x^2 + y^2 = 25 represents the set of points in 3D space where the distance from the origin to the point (x, y, z) is equal to 5. The surface z = xy represents the set of points in 3D space where the height of the point (x, y, z) is equal to its x-y coordinate.

The curve of intersection of the two surfaces is given by the set of points in 3D space that are simultaneously on the cylinder and on the surface z = xy. This means that for any point on the curve of intersection, the distance from the origin to the point must be equal to 5, and the height of the point must be equal to its x-y coordinate.

We can find a vector function that represents the curve of intersection by parameterising the points on the curve in terms of a scalar parameter t. For example, a possible parameterization of the curve of intersection is:

r(t) = (5 cos(t), 5 sin(t), 5 cos(t) sin(t))

where t is a scalar parameter that ranges over all values between 0 and 2π. The values of x, y, and z are given by 5 cos(t), 5 sin(t), and 5 cos(t) sin(t), respectively, and represent a point on the curve of intersection for each value of t.
