consider the following pattern: 5;8;11; ... ; ...
a) determine the common difference of the pattern
b) write the next two terms of the pattern
c) determine the general term
d) determined T²⁰ of the pattern
Answer:
Step-by-step explanation:
The common difference is 8-5 = 3
The first next term is 11 + 3 = 14
The next (second) term is 14 + 3 = 17
tn = 5 + (n - 1)*3 This is part c
t20 = 5 + (20 - 1)*3
t20 = 5 + 19*3
t20 = 5 + 57
Answer t20 = 62
Find the center and radius of the circle with this equation:
x² + 16x + 64 + y² - 2y + 1 = 144
By completing squares, we will see that the radius is 12 units and the center is (-8, 1).
How to find the center and radius of the circle?The circle of center (x₁, y₁) and radius r is written as:
(x - x₁)² + (y - y₁)² = r²
Now we go to our equation:
x² + 16x + 64 + y² - 2y + 1 = 144
Now we need to complete squares:
(a + b)² = a² + 2ab + b²
Then we can rewrite:
(x² + 2*8*x + 8*8) + (y² - 2y + 1) = 12²
(x + 8)² + (y - 1)² = 12²
So the center is the point (-8, 1) and the radius is 12 units.

The graph of y=x² + 11x + 24 is equivalent to the graph of which equation?
y=(x+8)(x+3)
y=(x + 4)(x+6)
y=(x +9)(x + 2)
y=(x + 7)(x+4)
Answer:
y = (x+8)(x+3)
Step-by-step explanation:
If you multiply
(x+8)(x+3),
you get x^2 + 3x + 8x + 24
This simplifies to x^2 + 11x + 24, same as the original question.
The graph of y=x² + 11x + 24 is equivalent to the y=(x+8)(x+3).
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Constants and variables are components of a polynomial.
We have Graph whose equation is
y=x² + 11x + 24
Now, factories the above equation using splitting the middle term
y=x² + 11x + 24
y=x² + 8x + 3x + 24
y = x(x+8) + 3(x+8)
y= (x+3)(x+8)

Casho invests money in an account paying simple interest. She invests $30 and no
money is added or removed from the investment. After one year, she has $32.40.
What is the simple percent interest per year?
Answer:
8%
Step-by-step explanation:
Divide ( 32.40 / 30 ). This outputs the answer 1.08, or 108%. This means that the outcome is 108% of the original, or 8% greater.
The simple interest in which Casho invests money was 8%.
What is simple interest?
Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.
We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, p = 30, SI = (32.40 - 30) = $2.40 and t = 1.
Therefore, 2.40 = (30×r×1)/100.
240 = 30r.
r = 240/30.
r = 24/3.
r = 8.
So, The rate of simple interest is 8%.

The indicated side of the right triangle is [tex]44\sqrt{2} =\frac{88}{\sqrt{2} }[/tex].
RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called hypotenuse. And, the other two sides are called cathetus or legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.
The Pythagorean Theorem says:[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2[/tex]. And the main trigonometric ratios are:
[tex]sin(\beta )= \frac{opposite\;leg}{hypotenuse} \\ \\ cos(\beta )= \frac{adjacent\;leg}{hypotenuse} \\ \\ tan(\beta )= \frac{opposite\;leg}{adjacent\;leg} \\ \\[/tex]
The question asks to find one of the legs (y). Then, you can find y applying the trigonometric ratio (sin 45°).
[tex]sin(45\°)=\frac{y}{88}[/tex]
Like sin45° is equal to [tex]\frac{\sqrt{2} }{2}[/tex], you have
[tex]\frac{\sqrt{2} }{2} =\frac{y}{88}\\ \\ 2y=88\sqrt{2} \\ \\ y=44\sqrt{2} \\ \\ Thus\\ \\ y=\frac{88}{\sqrt{2}}[/tex]

The expression of time in terms of r is T = 85/9r. If he walked at an average speed of 3 miles per hour. Then the time taken by nick to reach the shopping mall will be 3 hours and 60 minutes.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Nick walked 5 miles to reach his aunt's house.
From there he traveled 8 miles to the shopping mall on a bicycle.
He traveled 80% faster on the bicycle than on foot.
Let r represent his rate of walking in miles per hour. Then the 1.8r will be the rate of cycling in miles per hour.
Then the number of hours nick took to reach the shopping mall in terms of r will be
T = t₁ + t₂
Where t₁ is the time taken to reach his aunt's house and t₂ is the time taken to reach the shopping mall from his aunt's house. Then we have
T = 5 / r + 8 / 1.8r
T = 1/r (5 + 8/1.8)
T = 85/9r
If r is 3 miles per hour, then the time taken by nick to reach the shopping mall will be
T = 85 / (9 x 3)

Answer:Calvin throws 12 sheets of paper up in the air.
He randomly catches one of the sheets as they float down.
Of the 12 sheets of paper, 9 are white and 3 are red.
Probability = Number of favorable outcomes/ total number of outcomes
The probability that Calvin caught a white sheet is = or 75%.
It is likely that this event occurs as above 70% we say that the event is likely and here the probability is 75%.
The probability that Calvin caught a red sheet is = or 25%
This is unlikely to happen. Thus, we can say that it is not likely event.

Write an exponential equation for the graph shown
below.
Explain how you determined the equation.
The exponential equation of the graph is y = 1.59 * 1.26^x
How to determine the exponential equation?On the graph, we have the following points
(x,y) = (2,1) and (4,4)
An exponential function is represented as;
y = ab^x
So, we have:
ab^1 = 2 and ab^4 = 4
Divide both equations
b^3 = 2
Take the cube root of both sides
b = 1.26
Substitute b = 1.26 in ab^1 = 2
1.26a = 2
Divide both sides by 1.26
a = 1.59
So, we have:
y = ab^x
y = 1.59 * 1.26^x
Hence, the exponential equation of the graph is y = 1.59 * 1.26^x
