Step-by-step explanation:
Answer
Given
Sean's house is currently worth $188,900.
According to a realtor, house prices in Sean's neighborhood will increase by 4.8% every year.
To prove
Formula

Where r is the rate in the decimal form.
As given


= 0.048
Put in the formula


Now also calculated monthly.
Formula

As given


= 0.048
Put in the formula



As the approximation quarterly growth rate of the value of sean's house is near the Compounded quarterly interest .
Thus Option (A) is correct.
i.e
The expression
reveals the approximate quarterly growth rate of the value of Sean's house.
Answer:
Rs 175
Step-by-step explanation:
Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).
At Rs200, the profit is 200-x.
So we have an equation: minus 150 minus x is equal to 200 minus x.
To solve the equation, the cost price X is Rs175.
It is B because those two angles make it complementary
Answer:
See explanation
Step-by-step explanation:
Let x be the number of spade shovels, y -the number of flat shovels and z - the number of square showels sold that day.
The store keeps an inventory of 80 shovels, then
x+y+z=80
The store always buy twice as many spade shovels as square, so
x=2z
The total cost of all shovels is
16x+9.60y+12.80z=1,072
a) The system of three equations is

b) In matrix form this is

c) The determinant is

d) Find three determinants:



So,

e) If the store doubled all prices and inventory, then the new matrix is
