Is a diameter of 9cm more than a radius of 5cm and which would have the larger circumference?
Answers
Answer:
Circle B
3.14 cm
Step-by-step explanation:
1. The diameter is twice the radius, so the diameter of Circle B is ...
2 × 5 cm = 10 cm
This diameter is greater than the 9 cm diameter of Circle A, so Circle B is larger and will have a larger circumference.
2. The circumference is the product of π and the diameter. Then the difference between the two circumferences is ...
... (circle B circumference) - (circle A circumference) = π·(10 cm) - π·(9 cm)
... = π·(10 -9) cm = π·1 cm ≈ 3.14 cm

The value of the z statistic for the Exercise 22.22 is 2.53. This test is
(a) not significant at either α=0.05 or α=0.01.
(b) significant at α=0.05 but not at α ...not at α=0.01.
(c) significant at both and α=0.05 or α=0.01.
Answers
The correct answer to the given statistic question is (b) significant at α=0.05 but not at α=0.01. It is important to note that the significance level chosen for a test depends on the specific research question and the consequences of making a type I or type II error.
Based on the information provided, the value of the z statistic for Exercise 22.22 is 2.53. To determine the significance of this test, we need to compare it with the critical values of the standard normal distribution at the given significance levels. For α=0.05, the critical value is 1.96 and for α=0.01, the critical value is 2.58.
Since the value of the z statistic (2.53) is greater than the critical value at α=0.05 (1.96), we can say that the test is significant at α=0.05. However, the value of the z statistic is less than the critical value at α=0.01 (2.58), which means that the test is not significant at α=0.01.
Therefore, the correct answer to the given question is (b) significant at α=0.05 but not at α=0.01. It is important to note that the significance level chosen for a test depends on the specific research question and the consequences of making a type I or type II error.

You have been given 2 pairs of coordinates that lie on that line
First find the gradient (m) which is equal to change in y / change in x
(4,-1)
(-1,4)
Change in y = -1 - 4 = -5
Change in x = 4 - -1 = 5
Gradient = -5/5 = -1
So now we know y= -x + c
There is only one other unknown so we can sub in a pair of coordinates such as (4,-1)
-1 = -4 + c
Then solve:
Add 4 to both sides
3=c
So the equation of f is y = -x+3
Or f(x)= -x+3
Point a is where this line intersects the x axis, at this point, we know that y=0 which we can sub in
0= -x+3
And solve:
-3 = -x
3=x
So the coordinates of a are (3,0) and because we know that function g is symmetrical in the y axis (due to its form ax^2 + b), the coordinates of c must be (-3,0)
Subbing the coordinates both worked out and given into the function g we get
0 = 9a + b
And
-8 = a + b
Which we can solve simultaneously by subtraction:
0 = 9a + b
-8 = a + b -
——————
8 = 8a
So a = 1
So -8 = 1+b
So -9 = b
So the equation for g is y = x^2 -9
The length of ac is 6 and should be easy to see given the coordinates (3,0) and (-3,0)
The length ob is from the origin (0,0) to the turning point of y = x^2 -9 because the curve is symmetrical and we know it lies on the y axis so x=0 so y = -9
The difference between the coordinates (0,0) and (0,-9) is clearly 9
I hope this helped
Answer:
\(\textsf{1)} \quad f(x)=-x+3\)
2) A = (3, 0) and C = (-3, 0)
\(\textsf{3)} \quad g(x)=x^2-9\)
4) AC = 6 units and OB = 9 units
Step-by-step explanation:
Given functions:
\(\begin{cases}f(x)=mx+c\\g(x)=ax^2+b \end{cases}\)
Part (1)Given points:
H = (-1, 4)T = (4, -1)As points H and T lie on f(x), substitute the two points into the function to create two equations:
\(\textsf{Equation 1}: \quad f(-1)=m(-1)+c=4 \implies -m+c=4\)
\(\textsf{Equation 2}: \quad f(4)=m(4)+c=-1 \implies 4m+c=-1\)
Subtract the first equation from the second to eliminate c:
\(\begin{array}{r l} 4m+c & = -1\\- \quad -m+c & = \phantom{))}4\\\cline{1-2}5m \phantom{))))}}& = -5}\end{aligned}\)
Therefore m = -1.
Substitute the found value of m and one of the points into the function and solve for c:
\(\implies f(4)=-1(4)+c=-1\)
\(\implies c=-1-(-4)=3\)
Therefore the equation for function f(x) is:
\(f(x)=-x+3\)
Part (2)Function f(x) crosses the x-axis at point A. Therefore, f(x) = 0 at point A.
To find the x-value of point A, set f(x) to zero and solve for x:
\(\implies f(x)=0\)
\(\implies -x+3=0\)
\(\implies x=3\)
Therefore, A = (3, 0).
As g(x) = ax² + b, its axis of symmetry is x = 0.
A parabola's axis of symmetry is the midpoint of its x-intercepts.
Therefore, if A = (3, 0) then C = (-3, 0).
Part (3)Points on function g(x):
A = (3, 0)G = (1, -8)Substitute the points into the given function g(x) to create two equations:
\(\textsf{Equation 1}: \quad g(3)=a(3)^2+b=0 \implies 9a+b=0\)
\(\textsf{Equation 2}: \quad g(1)=a(1)^2+b=-8 \implies a+b=-8\)
Subtract the second equation from the first to eliminate b:
\(\begin{array}{r l} 9a+b & = \phantom{))}0\\- \quad a+b & =-8\\\cline{1-2}8a \phantom{))))}}& = \phantom{))}8}\end{aligned}\)
Therefore a = 1.
Substitute the found value of a and one of the points into the function and solve for b:
\(\implies g(3)=1(3^2)+b=0\)
\(\implies 9+b=0\implies b=-9\)
Therefore the equation for function g(x) is:
\(g(x)=x^2-9\)
Part 4The length AC is the difference between the x-values of points A and C.
\(\implies x_A-x_C=3-(-3)=6\)
Point B is the y-intercept of g(x), so when x = 0:
\(\implies g(0)=(0)^2-9=-9\)
Therefore, B = (0, -9).
The length OB is the difference between the y-values of the origin and point B.
\(\implies y_O-y_B=0-(-9)=9\)
Therefore, AC = 6 units and OB = 9 units

1. each block has a weight of 400 lb. determine how far the force p can compress the spring until block b slips on block a. what is p for this to occur?
Answers
The answer is 1. P = μs * 400 lb, and 2. we have static friction μs * 400 lb = k * x. From the given information, we can solve for P and find the value required for block B to slip on block A.
To determine how far the force P can compress the spring until block B slips on block A, we need to consider the equilibrium of forces acting on the system.
When the blocks are in equilibrium, the force P will be equal to the static friction between block A and block B, preventing slipping. The maximum static friction force can be calculated as the product of the coefficient of static friction (μs) and the normal force between the blocks.
The normal force between the blocks is equal to the weight of block B, which is 400 lb. Therefore, the maximum static friction force is μs * 400 lb.
Once the spring is compressed to a certain distance, it will exert a force in the opposite direction, opposing the force P. At the point of slipping, the force exerted by the spring will equal the maximum static friction force.
Therefore, we have P = μs * 400 lb.
To determine the distance the spring compresses, we need to consider Hooke's Law, which states that the force exerted by the spring is directly proportional to the distance it is compressed.
The equation can be written as P = k * x, where k is the spring constant and x is the distance of compression.
Combining both equations, we have μs * 400 lb = k * x.
From the given information, we can solve for P and find the value required for block B to slip on block A.
Please note that specific values for the coefficient of static friction (μs) and the spring constant (k) are needed to obtain a numerical result.

The unitary technique is a procedure that involves first determining the value of a single unit. After the process it followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs.
We can say that, 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's assume we need to calculate the price of 15 bananas.
This may be achieved as the following calculations: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
As per the question, An average human heart beats 60 times per minute.
Now, the amount of beats in an hour by the number of hours in a day.
= 3,600 x 24 hours
= 86,400 beats per day
Again, the amount of beats per year
= 86,400 x 365 days
= 31,536,000 beats per year
So, the heart beats

difference quotient. [: Check Answer
Answers
The difference quotient for the function f(x) = 69x + 2 is a constant value of 69. This means that the average rate of change of the function over any interval is always 69.
To evaluate and simplify the difference quotient for the function f(x) = 69x + 2, we first need to understand what the difference quotient represents. The difference quotient is a mathematical expression that measures the average rate of change of a function over a given interval. It is defined as:
[f(x + h) - f(x)] / h,
where h represents a small change in the x-values.
Let's proceed with calculating the difference quotient for the given function:
[f(x + h) - f(x)] / h
= [(69(x + h) + 2) - (69x + 2)] / h
= [69x + 69h + 2 - 69x - 2] / h
= (69h) / h
= 69.
To simplify the expression, we used the distributive property to expand the function f(x + h). Then, we simplified the numerator by combining like terms. The constant terms 2 and -2 canceled each other out. The h term in the numerator can be factored out, which allows us to cancel it out with the h term in the denominator. Finally, we are left with the simplified expression of 69.

Answers
The radius of the circle is 13.
To find the radius of the circle with the center at the origin and passing through the point (-12, 5), we can use the distance formula.
The distance formula between two points (x1, y1) and (x2, y2) is given by:
Distance = √[(x2 - x1)² + (y2 - y1)²]
In this case, the center of the circle is at the origin (0, 0), and the given point is (-12, 5). Plugging these values into the distance formula, we get:
Distance = √[(-12 - 0)² + (5 - 0)²]

Answers
The partition where the bundle branches are located is called the interventricular septum. The interventricular septum is a wall of tissue that separates the ventricles of the heart. It plays a crucial role in electrical conduction within the heart.
Within the interventricular septum, there are specialized bundles of cardiac muscle fibers known as the bundle branches. These bundle branches are responsible for transmitting electrical signals from the atrioventricular (AV) node to the ventricles, coordinating the contraction and pumping of blood.
The bundle branches consist of the left bundle branch and the right bundle branch. The left bundle branch further divides into the anterior and posterior fascicles, while the right bundle branch extends towards the right ventricle. These branches distribute electrical impulses to specific regions of the ventricles, ensuring synchronized and efficient contraction.
In summary, the partition where the bundle branches are located is known as the interventricular septum. It serves as a pathway for electrical signals to reach the ventricles, facilitating coordinated contraction and efficient pumping of blood.

Answers
The two points where the line meets the circle are (3,6) and (8,3).
To find the coordinates of the point where the line 2x+2y=18 meets the circle (x-2)^2+(y-3)^2=16, we need to first solve the system of equations.
We can start by simplifying the equation of the line by dividing both sides by 2, giving us x+y=9. We can then substitute y=9-x into the equation of the circle,
which results in (x-2)^2+(9-x-3)^2=16. Simplifying this equation yields x^2-4x+4+x^2-12x+81=16. Combining like terms and solving for x, we get x=3 or x=8.
Substituting these values back into the equation of the line gives us the corresponding y-coordinates of 6 and 3, respectively.

Answers
The function g(x) = (3x + 5) + 8 is a translation of 8 units upwards of f(x).
How does g(x) compares to f(x)?For a general function f(x), we define a vertical translation of N units as:
g(x) = f(x) + N
if N > 0, then the translation is upwards.
if N < 0, then the translation is downwards.
For a general function f(x), we define a horizontal translation of N units as:
g(x) = f(x) + N
if N > 0, then the translation is to the left.
if N < 0, then the translation is to the right.
Here we start at:
f(x) = 3x + 5
