Answer 1

Answer:

A ≈ 25.1 cm²

Step-by-step explanation:

The area (A) of the shaded region is calculated as

A = area of circle × fraction of circle

   = πr² × [tex]\frac{\frac{4\pi }{9} }{2\pi }[/tex]

   = π × 6² × [tex]\frac{\frac{4\pi }{9} }{2\pi }[/tex] ← cancel π and 2π by π

   = 36 × [tex]\frac{\frac{4\pi }{9} }{2}[/tex]

   = 18 × [tex]\frac{4\pi }{9}[/tex]

   = 2 × 4π

   = 8π ≈ 25.1 cm² ( to 1 dec. place )

The function which has greater slope is Function 2.

What is Slope?

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:

Function 1:

y = -2x + 10

and Function 2:

Slope = (5-10)/( 2-0) = -5/2

So, the Equation of line

(y - 10) = -5/2 (x -0)

y - 10 = -5/2x

y = -5/2x + 10

y= -2.5x +10

So, the slope of Function 1 is greater than slope of function 2.

The equivalent expressions of 10/9 + 2/9m − 4/9n are 2/9(5 + m - 2n) and -2/9(2n − m − 5)

How to determine the equivalent expressions

From the question, we have the following parameters that can be used in our computation:

109+ 29m − 49n

Express the expression properly

So, we have the following representation

10/9 + 2/9m − 4/9n

Factor out 2/9

So, we have

2/9(5 + m - 2n)

Factor out -1 from the expression

So, we have the following representation

-2/9(2n − m − 5)

Hence, the equivalent expression is -2/9(2n − m − 5)

Answers

According to a recent study of 35 students,Population-wide, there was a 2.8-hour standard deviation. 16.60 is the population mean's 95% confidence interval.

What means 95% confidence interval?A Confidence Interval is a zone created using sampled data from a population (sample space) that has a fixed size and follows a specific probability distribution. The interval is built to include a selected population statistic with a certain probability. A range of values above and below the point estimate, within which the true value in the population is likely to reside with 95% confidence, is known as a 95% confidence interval. 5% of the time, the true result might not fall inside the confidence interval.A confidence interval that includes the value of no difference between treatments denotes that there is no statistically significant difference between the therapy under consideration and the control.The result is that P([sample mean] - margin of error [sample mean] + margin of error) = 0.95.

The volume of the pyramid shown is 16√3 cm³.

What is Volume?

Volume of a three dimensional shape is the space occupied by the shape.

Given a solid oblique pyramid.

It has an equilateral triangle as a base with an edge length of 4√3 cm and an area of 12√3 cm².

Volume of the pyramid = 1/3 × base area × height

Base area = 12√3 cm²

Height = 4√3 × tan (30°) = 4√3 × 1/√3 = 4

Volume = 1/3 × 12√3 × 4

             = 16√3 cm³

Hence the volume is 16√3 cm³.

A triangle is placed in a semicircle with a radius of 2 yd, as shown below. Find the area of the shaded region. Use the value 3.14 for pie, and do not round your answer. Be sure to include the correct unit in your answer.

Answer:

Step-by-step explanation:

From the question we are told that:

Radius [tex]r=2yd[/tex]

Pie [tex]\pi=3.14[/tex]

Generally the equation for Area of the shaded part [tex](A_s)[/tex] is mathematically given by

[tex]A_s=Area\ of\ semi-circle(A_c)-Area\ of\ triangle(A_t)[/tex]

Generally the equation for Area of semi-circle is mathematically given by

 [tex]A_c=\frac{1}{2}\pi r^2[/tex]

 [tex]A_c=\frac{1}{2}*(3.14) (2)^2[/tex]

[tex]A_c=6.28yd^2[/tex]

Generally the equation for Area of triangle is mathematically given by

 [tex]A_t=\frac{1}{2} base*height[/tex]

 [tex]A_t=\frac{1}{2} (2+2)*2[/tex]

 [tex]A_t=4yd^2[/tex]

Therefore Area of the shaded part [tex](A_s)[/tex]

 [tex]A_s=A_c-A_t[/tex]

 [tex]A_s=6.28yd^2-4yd^2[/tex]

What is 24.21 written in expanded form?

Answers

Answer:

(2 x 10) + (4 x 1) + (2 x 0.1) + (1 x 0.01)

Step-by-step explanation:

The expanded form of 24.21 = (20 + 4 + 0.2+ 0.01)

The expanded form of an equation requires writing out the place value term of each digit of the number given :

24.21 :

Tens digit = 2 × 10 = 20

Unit digit = 4 × 1 = 4

Tenth digit = 2 × 0.1 = 0.2

Hundredth digit = 1 × 0.01 = 0.01

Hence, the expanded form of the number is :

The rule for g(x) = f(x-1)-3 is g(x) = (x-1)⁶-3(x-1)³ - 1

How to write the rule for g(x) = f(x-1)-3?

A function is an expression, rule, or law that defines a relationship between an independent variable and a dependent variable. Based on the information given, we can see that the variables that are illustrated in the question are f and g.

In order to write the rule for g(x) = f(x-1)-3 when f(x) = x⁶ - 3x³ + 2, replace x with x-1 in f(x) and subtract 3. That is:

g(x) =  f(x - 1) - 3

g(x) = (x-1)⁶ - 3(x - 1)³ + 2 - 3

g(x) = (x-1)⁶ - 3(x - 1)³- 1

0.25x + 0.05y = 4.60

Answers

The situation involving coins that is modeled by the system of equations x + y = 24, 0.25x + 0.05y = 4.60 is given as follows:

You have a combination of 24 quarters and cents, and the total you have is of $4.60. How many coins of each type you have.

What is the system of equations?

To obtain the meaning of each of the variables x and y, we look at the second equation, given as follows:

0.25x + 0.05y = 4.60.

This means that:

The variable x represents the total number of quarters, as each quarter coin is worth $0.25.The variable y represents the total number of nickels, as each nickel coin is worth $0.05.

The result of this sum means that the total amount of money that you have is of $4.60.

The first equation is given as follows:

x + y = 24.

Which means that the total number of coins that you have is of 24.
