What is the equation of a circle with a center of (-2, -1) and radius of √2?
Answer:
(x + 2)² + (y + 1)² = 2
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
Here (h, k) = (- 2, - 1) and r = [tex]\sqrt{2}[/tex], thus
(x - (- 2))² + (y - (- 1))² = ([tex]\sqrt{2}[/tex] )², that is
(x + 2)² + (y + 1)² = 2 ← equation of circle

Write a situation that could be represented by the algebraic expression 3s + 2.15.
The algebraic expression '3s + 2.15' can represent a real-life situation where you're shopping for food. If sandwiches cost $3 each and a soda costs $2.15, the total you'd spend on 's' sandwiches and one soda is 3s + 2.15 dollars.
Explanation:Here is a scenario that could represent the expression 3s + 2.15: Imagine you're in a store and each sandwich costs $3.00. You're planning to buy 's' number of sandwiches. Now, let's say you also want to buy a soda which costs $2.15. The total cost you will spend in the store would be the cost of the 's' sandwiches plus the cost of the soda, which can be represented by the expression 3s + 2.15. So if you bought 2 sandwiches, the total cost would be 3*2 (for the sandwiches) + 2.15 (for the soda) = $8.15.

In any given year, a factory has a 20% probability of having an accident. About every how many years might the factory expect to have an accident?
Every 1 year
Every 2 years
Every 5 years
Every 20 years
Answer:
Probability of having an accident = 20% o 0.2
Thus,
Expected number of years = 1/probability of accident = 1/0.2 = 5
Hence,
3. Every 5 years is the correct option.
Step-by-step explanation:
The factory will expect to have an accident every 5 years.
The probability of having an accident in the factory = 20% = 20/100 = 0.2
It should be noted that the highest likelihood for an event happening is 100% which is represented by 1.
Therefore, the number of years that the factory expect to have an accident will be:
= 1 / probability of having an accident
= 1/0.2
= 5 years
In conclusion, the factory will expect an accident every 5th year.

Regina is tying a bow around a soccer ball to give to her sister. The ball has a radius of 4.5 inches. If the ribbon needs to be 10 inches longer than the circumference of the ball so she has enough room to tie a bow , how many inches of ribbon will she need?
The circumference of the soccer ball can be found using the formula for the circumference of a circle, to which 10 inches is then added to find the total length of the ribbon Regina needs.
Explanation:The problem involves understanding the mathematical concept of circumference. The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, the soccer ball has a radius of 4.5 inches. Therefore, the circumference of the soccer ball would be C = 2π(4.5) inches.
Then, the problem states that the ribbon needs to be 10 inches longer than the circumference of the ball. So the total length of the ribbon that Regina needs is C + 10 inches. By substituting the values, we get the length of the ribbon needed.

Find the zeros of the function.
Write the smaller solution first, and the larger solution second.
g(x)=(-5x– 1)(2x + 8)
smaller x=
larger x =
Answer:
x = - 4, x = - [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
To find the zeros let g(x) = 0, that is
(- 5x - 1)(2x + 8) = 0 ← in standard form
Equate each factor to zero and solve for x
- 5x - 1 = 0 ( add 1 to both sides )
- 5x = 1 ( divide both sides by - 5 )
x = [tex]\frac{1}{-5}[/tex] = - [tex]\frac{1}{5}[/tex]
2x + 8 = 0 ( subtract 8 from both sides )
2x = - 8 ( divide both sides by 2 )
x = - 4
Thus
smaller x = - 4
larger x = - [tex]\frac{1}{5}[/tex]
Quadrilateral ABCD is inscribed in this
circle.
What is the measure of angle A?
Enter your answer in the box.
The measure of angle A is 88°.
Solution:
Given data:
∠A = (2x – 40)°, m∠B = 116° and ∠D = x°
A quadrilateral inscribed in a circle is called cyclic quadrilateral.
∠B and ∠D are opposite angles in a cyclic quadrilateral.
In cyclic quadrilateral, opposite angles are supplementary.
⇒ m∠B+ m∠D = 180°
⇒ 116° + x = 180 °
Subtract 116° from both sides of the equation, we get
⇒ x = 64 °
To find the measure of angle A:
m∠A = (2x – 40)°
= 2(64°) – 40°
m∠A = 88°
Hence the measure of angle A is 88°.

The length of a rectangle is 3cm more than twice the width. The perimeter is 84 cm. Find the dimensions .
Width of the rectangle is 13 cm and length is 29 cm.
Step-by-step explanation:
Step 1:
Given perimeter of the rectangle = 84 cm. Let the width be x, then the length of the rectangle = 2x + 3. Use the formula for perimeter of a rectangle = 2(length + width) to find the dimensions.
84 = 2(2x + 3 + x) = 2(3x + 3) = 6(x + 1) [taking 3 as common factor outside)
⇒ 84 = 6x + 6
⇒ 78 = 6x
∴ x = 13
⇒ Width of the rectangle = 13 cm
∴ Length of the rectangle = 2x + 3 = 29 cm

Ava said she wrote an expression with three terms. She said the first term ha the coefficient 7,the second term have the coefficient 1,and the third has the coefficient 0.1. Each term involves a different variable. Write an expression that could be the expression ava wrote.
Answer:
7*x + y + 0.1*z
Step-by-step explanation:
An expression that satisfy what Ava said she wrote is the following:
7*x + y + 0.1*z
because
it has 3 terms (each summand);the coefficient (the number that multiplies the variable) of the first term is 7, of the second term is 1 (it is omitted because 1*y = y) and of the third term is 0.1;each term involves a different variable: x, y and z.Answer:
The expression can be written as
7a + b + 0.1c
Step-by-step explanation:
Ava wrote an expression with three terms . According to the question each term involve a different variable. This means the term have different value. Since the term have different variable, each term can be represented as follow:
a , b and c
The first term which is a has a coefficient of 7. The second term which is b has a coefficient of 1 and the last term which is c has a coefficient of 0.1.
The coefficient of any value is usually the number in front of it.
The three terms and their coefficients can be expressed as follows:
First term and coefficient = 7a
Second term and coefficient = 1b
Third term and coefficient = 0.1c
The expression Ava wrote can be represented as follows
7a + b + 0.1c
Note an expression that contains variable , symbols( +, - ) and numbers is known as an algebraic expression. And
7a + b + 0.1c is an algebraic expression.

Tyrone launches a toy rocket into the air with an initial upward velocity of 49 ft/s and an initial height of 0 ft. a. How long will it take the rocket to reach its maximum height? Round to the nearest hundredth. b. How high above the ground will it be? Round to the nearest tenth. c. What is the range of the function? d. Why is there a maximum point on the graph of this function?
a. It will take 1.53 seconds for the rocket to reach its maximum height.
b. The rocket will reach a maximum height of 38.04 ft (rounded to the nearest tenth).
c. The range of the function h(t) is bounded below by h0 (0 ft) and above by h_max (38.04 ft). In mathematical notation, the range is:
Range = {h | h ∈ R, h0 ≤ h ≤ h_max}
d. The maximum point on the graph of the function exists because of the negative coefficient of the t^2 term (-16).
**a. Time to reach maximum height:**
The rocket's motion can be modeled by the formula:
h(t) = -16t^2 + vt + h0
where:
* h(t) is the height of the rocket at time t
* t is the time in seconds
* v is the initial upward velocity (49 ft/s)
* h0 is the initial height (0 ft)
We need to find the time t when the height h(t) is maximum. Since the acceleration due to gravity (-16 ft/s^2) is negative, the maximum height happens at the vertex of the parabola represented by the equation.
The time to reach the vertex can be found using the formula:
t_vertex = -v / (2a) = -49 / (2 * -16) = 1.53 seconds (rounded to the nearest hundredth)
Therefore, it will take 1.53 seconds for the rocket to reach its maximum height.
**b. Maximum height:**
Now, plug the t_vertex value back into the equation to find the maximum height:
h(1.53) = -16(1.53)^2 + 49(1.53) + 0 = 38.04 ft
Therefore, the rocket will reach a maximum height of 38.04 ft (rounded to the nearest tenth).
**c. Range of the function:**
The range of the function depends on the initial parameters (velocity and height) and the gravitational acceleration. Since the acceleration due to gravity is always negative, it acts as a downward force pulling the rocket back down. This means the highest point the rocket can reach is its initial height plus the maximum height achieved due to the initial velocity.
Therefore, the range of the function h(t) is bounded below by h0 (0 ft) and above by h_max (38.04 ft). In mathematical notation, the range is:
Range = {h | h ∈ R, h0 ≤ h ≤ h_max}
**d. Reason for the maximum point:**
The maximum point on the graph of the function exists because of the negative coefficient of the t^2 term (-16). This term represents the downward force due to gravity, which continuously slows down the rocket's upward motion. Eventually, the upward velocity becomes zero, and the rocket starts descending due to gravity. This point of zero velocity corresponds to the vertex of the parabola, which represents the maximum height achieved.
