(1) If the number in the tens position is less that 5, then, all you will do is convert the tens and units of the original number to zeros and that's it.
(2) If the number in the tens position is 5 or more, then you will add one to the hundreds and then convert the tens and units to zeros.
Taking a look at the number we have (12,000), we will find that the number in the hundreds position is a zero, which means that the second case is invalid here.
This means that, the number might be any number whose tens is less than 5.

Final answer:
The trinomial expression equivalent to (2x+5)(3x-2) is calculated using the FOIL method, resulting in 6x² + 11x - 10.
Explanation:
To write a trinomial expression equivalent to the product of two binomials, (2x+5)(3x-2), we perform the multiplication by using the distributive property (also known as the FOIL method).
Multiply the first terms: 2x × 3x = 6x²
Multiply the outside terms: 2x × (-2) = -4x
Multiply the inside terms: 5 × 3x = 15x
Multiply the last terms: 5 × (-2) = -10
Combine like terms:
6x² + (15x - 4x) - 10 = 6x² + 11x - 10
The trinomial expression equivalent to (2x+5)(3x-2) is 6x² + 11x - 10.
The formula A=P(1+r)t is used to show the total amount owed for a loan with a simple annual interest rate.
Solve for r.
Answers
We first divide both sides of the equation by t, which gives us
[tex]\displaystyle{ \frac{A}{t}=P(1+r) [/tex],
then, dividing both sides by P, we have
[tex]\displaystyle{ \frac{A}{Pt}=1+r [/tex].
Swap the sides:
[tex]\displaystyle{ 1+r= \frac{A}{Pt}[/tex]
Finally subtracting 1 from both sides gives us
[tex]\displaystyle{ r=\frac{A}{Pt}-1[/tex].
Answer: [tex]r=(\frac{A}{P})^{\frac{1}{t}}-1[/tex]
Step-by-step explanation
Compound interest is the addition of interest to the principal sum of a deposit or a loan.
Let P = principal amount which was taken as a loan then the accumulated amount A is given by
[tex]A=P(1+r)^t[/tex].......(1)
where, r is the rate of simple annual interest in decimal.
t is the time applied for interest.
For solving r divide both sides of equation by P in (1),we get
[tex]\frac{A}{P}=(1+r)^t\\\Rightarrow(\frac{A}{P})^{\frac{1}{t}}=1+r\\\Rightarrow\ r=(\frac{A}{P})^{\frac{1}{t}}-1[/tex].
Given right triangle def what is the value of sin e

A polygon has an area of 144 square inches and one of its sides is 10 inches long. If a second similar polygon has an area of 64 square inches, what is the length of the corresponding side in the second polygon?
Answers
or, put it in another way,
side length is proportional to sqrt(area).
so for the given case,
area = 144, sqrt(area)=12, side length = 10.
area = 64, sqrt(area)=8, side length = X
By proportion,
X/8 = 10/12
solve for X
X=(10/12)*8=20/3 = 6 2/3 = 6.67 (approx.)
So side length of second polygon is approx. 6.67 in., or 6 2/3 inches.

The surface area of a right circular cylinder of height 4 feet and radius r feet is given by S(r)=2πrh+2πr2. Find the instantaneous rate of change of the surface area with respect to the radius, r, when r = 4. (2 points)
Select one:
a. 24π
b. 16π
c. 64π
d. 20π
Answers
For the first part, solve the equation you were given to find the time at which the height of the ball is 0. Sos(t) = -16t^2 - 64t + 800 = -16t^2 - 64t + 80
This is a standard quadratic equation that you can solve using the quadratic formula with a = -16, b = -64, and c = 80, so the roots are: 1 and -5.We can ignore the -5 root since that's what the situation would have looked like if we went back in time 5 seconds and launched the ball upwards from the ground. But since we're not doing time travel, the solution of interest is the 1. So the ball hits the ground one second after throwing it.The formula for distance under constant acceleration is d = 1/2 A T^2. That formula accounts for the -16t^2 term, so A is 32. So during that 1 second it takes for the ball to hit the ground, it will be accelerated 1 * 32 = 32 ft/sec. That is added to the initial velocity the ball was given. So at the moment it hits the ground it's going-64 ft/sec - 32 ft/sec = -96 ft/sec.
For the second problem, the key thing to note is "instantaneous rate of change". When you see that phrase you should immediately think "first derivative". So let's calculate the first derivative of the equation given.S(r)=2πrh+2πr^2S'(r)=2πh+4πr
Now substitute the value 4 for r, givingS'(4)=2πh+4π4 = 2πh+16π
And we have a problem. That value isn't one of the available options, so something is wrong. The problem is choice "b" takes into account the increase in surface area for the end caps on the cylinder, but it doesn't take into account the increase in surface area for the side of the cylinder which is what the 2πh term accounts for. Please show this to your teacher.
The instantaneous velocity of the ball when it hits the ground is found by deriving the height function and solving for the time of impact. The instantaneous rate of change of the surface area of a cylinder with respect to its radius when r = 4 is found by differentiating the surface area function and evaluating at r = 4.
The student's question involves two separate parts of physics and calculus related to kinematics and surface area calculations.
Part 1: Instantaneous Velocity of the Ball
The height, s, of a ball thrown straight down with initial speed 64 ft/sec from a cliff 80 feet high is given by s(t) = -16t2 - 64t + 80. The instantaneous velocity when the ball hits the ground is the derivative of position with respect to time, s'(t), evaluated at the time t when s(t) = 0 (when the ball hits the ground).
First, we find t by solving -16t2 - 64t + 80 = 0. Then, we find the derivative s'(t) = -32t - 64 and evaluate it at the found time, which gives us the instantaneous velocity.
Part 2: Rate of Change of Surface Area
The surface area of a right circular cylinder of height 4 feet and radius r feet is given by S(r) = 2πrh + 2πr2. The instantaneous rate of change of the surface area with respect to the radius, when r = 4, is the derivative dS/dr evaluated at r = 4. This is done by differentiating S(r) with respect to r and substituting r = 4 into the resulting expression.

Solve for y: 10y + 3.8 = 38.8
Answers
The solution for ( y ) is ( y = 3.5 ).
To solve for y in the equation [tex]\( 10y + 3.8 = 38.8 \)[/tex], follow these steps:
Start with the given equation:
[tex]\[ 10y + 3.8 = 38.8 \][/tex]
Subtract 3.8 from both sides to isolate the term with y:
[tex]\[ 10y + 3.8 - 3.8 = 38.8 - 3.8 \][/tex]
[tex]\[ 10y = 35 \][/tex]
Divide both sides by 10 to solve for y :
[tex]\[ \frac{10y}{10} = \frac{35}{10} \][/tex]
y = 3.5
So, the solution for ( y ) is ( y = 3.5 ).

Answer is C x=50 y=10
Answers
Answer:
C. [tex]x=50[/tex], [tex]y=10[/tex]
Step-by-step explanation:
We have been given an image of two intersecting lines. We are asked to find the value of x and y for our given diagram.
We know that when two line intersect each other, then vertical angles are congruent.
Using vertical angles theorem, we will get a system of equations as sown below:
[tex]3y=x-20...(1)[/tex]
[tex]5x-100=y+140...(2)[/tex]
From equation (1), we will get:
[tex]x=3y+20[/tex]
Upon substituting this value in equation (2), we will get:
[tex]5(3y+20)-100=y+140[/tex]
[tex]5*3y+5*20-100=y+140[/tex]
[tex]15y+100-100=y+140[/tex]
[tex]15y=y+140[/tex]
[tex]15y-y=y-y+140[/tex]
[tex]14y=140[/tex]
[tex]\frac{14y}{14}=\frac{140}{14}[/tex]
[tex]y=10[/tex]
Therefore, the value of y is 10.
To find the value of x, we will substitute [tex]y=10[/tex] in equation (1) as:
[tex]3*10=x-20[/tex]
[tex]30=x-20[/tex]
[tex]30+20=x-20+20[/tex]
[tex]50=x[/tex]
Therefore, the value of x is 50 and option C is the correct choice.
Answer:
Option C) x = 50, y = 10
Step-by-step explanation:
We are given a two pairs of vertically opposite angle in the image.
Vertically opposite angle is formed when two lines intersect anf they are always equal.
Thus, we can write:
[tex]3y = x -20\\\Rightarrow x - 3y = 20\\5x-100 = y +140\\\Rightarrow 5x - y =240[/tex]
Solving the two equations in two variable, we get:
[tex]x - 3y = 20\\5x - y =240\\\text{Multiplying first equation by 5}\\5x - 15y = 100\\\text{Subtracting the equations}\\5x - 15y-(5x-y) = 100-240\\-14y = -140\\y = 10\\ x - 3(10) = 20\\x = 20 + 30\\x =50[/tex]
The value of x is 50 and y is 10.

Joint PMF of X and Y
To find the joint PMF P(X = x, Y = y, we use the law of total probability:
[tex]P(X = x, Y = y) = P(Y = y \mid X = x) \cdot P(X = x)[/tex]

Simplify the expression:
[tex]P(X = x, Y = y) = \frac{e^{-10} \cdot 10^x}{x!} \binom{x}{y} \left(\frac{3}{4}\right)^y \left(\frac{1}{4}\right)^{x-y}.[/tex]
