Answer:
$9828.44
Step-by-step explanation:
The semi annual payment is such that the future value of the annuity due is equal to the desired amount when he retires.
The formula to calculate future value of an annuity due periodic payment of M for time period T for given periodic return r,
A=[tex]\frac{M(1+r)^{T+1}-(1+r)}{r}[/tex]
in this question there are 30*2= 60 payments and the semi annual rate= 4.5/2= 2.25%
putting values we get
1250675= [tex]\frac{M(1+2.25%)^{60+1}-(1+2.25%)}{2.25%}[/tex]
on solving we get M= $9828.44

Graph the line for y+1=−35(x−4) on the coordinate plane.
Just write what the coordinates would be
Answer:
(0, 139) and (139/35, 0)
Step-by-step explanation:
To graph a line, two points are needed. Taking x = 0 and replacing this value in the equation, we get:
y+1=−35(0−4)
y = 140 - 1
y = 139
Then, the point (0, 139) is on the line.
Taking y = 0 and replacing this value in the equation, we get:
0+1=−35(x−4)
1/(-35) = x -4
1/(-35) + 4 = x
139/35 = x
3.971 = x
Then, the point (139/35, 0) is on the line.
A pizza parlor has 8 different toppings and 3 different cheeses to choose from on the menu. How many pizza combinations are possible if each pizza has 1 topping and 1 cheese
Final answer:
To find the number of pizza combinations available using 1 topping and 1 cheese from 8 different toppings and 3 different cheeses, one multiplies the number of topping choices by the number of cheese choices, giving 8 x 3 = 24 possible combinations.
Explanation:
Calculating Pizza Combinations
When calculating the number of possible pizza combinations with 1 topping and 1 cheese from 8 different toppings and 3 different cheeses, we use basic counting principles. Each pizza can be thought of as a combination of one topping and one cheese. Since these choices are independent, we multiply the number of options for toppings by the number of options for cheeses to find the total combination possibilities. This results in 8 toppings multiplied by 3 cheeses, giving 24 possible combinations.
The formula used is straightforward: Number of combinations = Number of toppings × Number of cheeses.
Pizza Combination Calculation Example
For instance, if you were at a pizza parlor where you could choose from pepperoni, mushrooms, onions, and 5 other toppings, along with mozzarella, cheddar, and one other cheese, you could create 24 unique pizzas. Just pick one topping and one cheese, and that's your combination.

Scott bought three bags of candy with 75 pieces in each one. He plans to divide all the candy evenly among seven friends. How many pieces of candy will Scott have left for himself?
Answer:
The answer is only one piece of candy
Step-by-step explanation:
Firstly, we have to determine the total amount of pieces of candy:
There are three bags with 75 pieces in each one, so the total is:
[tex]75+75+75=225[/tex]
Then, in order to determine the amount of pieces of candy for every friend,
we have to divide the total amount by 7, where the remainder of the division is the answer.
[tex]\frac{225}{7}=32*7+1[/tex]
Remainder=1
Finally, every friend of Scott receive 32 pieces of candy evenly and Scott is left with only one piece of candy.
Find the solution of the differential equation 3e^(3x)dy/dx=â9x/y^2
To solve the given differential equation, variables need to be separated, followed by integration of both sides. Since the equation involves both exponential and inverse square terms, separation of variables and integration are key steps. A specific solution also requires substituting a given function of y into the found general solution to determine any integration constants.
Explanation:The question involves solving a differential equation 3e^(3x)dy/dx = -9x/y^2. First, we need to recognize this as a separable differential equation, which can be solved by isolating all terms involving y on one side and all terms involving x on the other side. After separation, we integrate both sides with respect to their respective variables.
Step 1: Separate the variables. We get dy/y^2 = -3x e^(-3x) dx.
Step 2: Integrate both sides. The integration of dy/y^2 with respect to y is -1/y, and the integration of -3x e^(-3x) with respect to x requires integration by parts or a table of integrals.
Step 3: Upon integration, we would find an implicit solution involving y and x, combined with an integration constant that needs to be determined based on initial conditions or additional information. Since specific initial conditions are not provided in the initial question, we'd include a constant C in our final expression.
For a specific solution when y(x) = cos(3x), additional steps are required to substitute this y expression into our general solution and solve for the constant.

A machine laying underground cable can place 125 meters of cable in 5 minutes
The machine lays cable at a rate of 25 meters per minute. This is calculated by dividing 125 meters by 5 minutes.
To determine how quickly the machine can lay underground cable, we need to calculate the rate of cable it places per minute. We start by noting that the machine can lay 125 meters of cable in 5 minutes.
We calculate the rate as follows:
Divide the total length of cable by the total time: 125 meters / 5 minutes = 25 meters per minute.This means the machine lays cable at a rate of 25 meters per minute.
Complete Question: A machine laying underground cable can place 125 meters of cable in 5 minutes. What is the rate per minute?

determine whether each equation is a linear equation. write yes or no. if yes, write the equation in standard form. if the answer is no, circle the part that makes it no
1. y = 4 - 2x
The given equation y = 4 - 2x is a linear equation, however, it is not in standard form. The standard form is 2x + y = 4.
Explanation:The equation y = 4 - 2x is indeed a linear equation. A linear equation is an equation that represents a straight line when graphed. It generally has the form 'y = mx + b' where 'm' represents the slope of the line, and 'b' represents the y-intercept. Here, 'm' is -2 and 'b' is 4.
However, it is not currently in standard form. The standard form of a linear equation is 'Ax + By = C', where A, B, and C are integers, and A and B are not both zero. To write the equation in standard form, we can re-arrange it as 2x + y = 4.

If y =18 and x=60 what is the constant of proportionality
Final answer:
The constant of proportionality when y = 18 and x = 60 is calculated by dividing y by x, which results in a constant of 0.3.
Explanation:
To find the constant of proportionality when y = 18 and x = 60, we must assume that the relationship between y and x is directly proportional. This means that as x increases, y increases at a constant rate, and vice versa. If the relationship is directly proportional, we can write y = kx, where k is the constant of proportionality.
To calculate k, we simply divide y by x. So we have:
k = y / x
k = 18 / 60
k = 0.3
Therefore, the constant of proportionality is 0.3.
