A company has borrowed $50000 at 10% compounded quarterly. The debt is amortized by equal payment each quarter ove 15 years. Find the quarterly payments and how much interest will be paid?
7500000 is interest will pay quarterly .
What do compound and simple interest mean?
Simple Interest is the amount returned for using the borrowed funds over a predetermined amount of time. When the total principal amount surpasses the payment due date and the interest rate over a certain period of time, this is known as compound interest. S.I. = (P, T, and R) x 100 is the formula.p = $50000
r = 10%
t = 15 years
interest = 50000 * 10 * 15 /100
= 7500000

If the mean span of automobile tires is 34000 miles and standard deviation is 2350 miles then the z scores that corresponds to the life spans of sample showing 33000 miles,37000 miles and 32000 miles are -0.4255, 1.2766 and -2.1277.
Given that mean span of automobile tire is 34000 miles and standard deviation is 2350 miles.
We are required to find the z score of the sample of 33,000 miles, 37,000 miles, and 32,000 miles.
A z-score basically gives us an idea of how far from the mean a data point is.
Z=(X-μ)/σ
In our case we have to find the mean of life span of three samples.
For the life span of 33000 miles,
Z=(33000-34000)/2350
=-1000/2350
=-0.4255
For the life span of 37000 miles,
Z=(37000-34000)/2350
=3000/2350
=1.2766
For the life span of 32000 miles,
Z=(32000-37000)/2350
=-5000/2350
=-2.1277
Hence if the mean span of automobile tires is 34000 miles and standard deviation is 2350 miles then the z scores that corresponds to the life spans of sample showing 33000 miles,37000 miles and 32000 miles are -0.4255, 1.2766 and -2.1277.

The value of given function is f'(x)=4 e^sin(x)cos (x)
WHAT IS DERIVATIVE?The derivative is what calculus is all about. The instantaneous pace at which a function changes with regard to one of its variables is known as the derivative. Finding the slope of the tangent line to the function at a given point is equal to doing this.
CALCULATIONf'(x) = d/dx ( 4 e^sin(x))
using differential rule d/dx (a x f ) = a x d/dx(f)
f'(x) = 4 x d/dx ( e ^ sin(x))
use the chain rule
f'(x)= 4 x d/dg ( e^g) x d/dx (sin (x))
f'(x)= 4 e^g x d/dx (sin (x))
f'(x)= 4 e^g x cos (x)
f'(x)=4 e^sin(x) x cos (x)

A linear function has the equation 4x+6y= 50. What is the
value of a when y = 3?
x =
Answer: x=8
Step-by-step explanation:
4x+6y=50
4x+6(3)=50
4x+18=50
4x=32
x=8
The value of x when y = 3 in the linear function 4x + 6y = 50 is x = 8.
Use the concept of linear fucntion defined as:
The formula for a linear function is f(x) = mx + b, where m and b are real values. The slope-intercept form of a line is represented by the equation,
y = mx + b.
The given linear fucntion is:
4x+6y= 50
To find the value of x when y = 3,
Substitute y with 3 in the equation and solve for x.
4x + 6(3) = 50
4x + 18 = 50
To isolate x,
Subtract 18 from both sides:
4x = 50 - 18
4x = 32
Now we divide both sides by 4:
x = 32/4
x = 8
Hence,
When y = 3, the value of x in the linear function 4x + 6y = 50 is 8.

On being asked her age, Shalu replies, 'My brother was born 2 years before me and my sister 4 years after me, and the sum of their ages is 30 years." How old is Shalu?
Shalu is 16 years old.
The equation can be defined as a mathematical term that refers to a situation in which several factors must be considered. It is defined as the state of being equal and is frequently represented as a math expression with equal numbers on either side.
Two expressions joined by an equal sign form a mathematical statement known as an equation.
Shalu's brother was born 2 years before Shalu.
Shalu's sister was born 4 years after Shalu.
And the sum of Shalu's brother and sister's age is 30 years.
Let x be the age of Shalu.
As Shalu's brother was born 2 years before her = x + 2
As Shalu's sister was born 4 years after her = x - 4.
Therefore,
x + 2 + x - 4 = 30
2x - 2 = 30
Adding 2 on each side of the equation,
2x -2 + 2 = 30 + 2
2x = 32
Dividing each side of the equation by 2.
2x / 2 = 32 / 2
x = 16
Therefore, Shalu is 16 years old.
