Answer:
actual rate of interest is 2.08 %
Step-by-step explanation:
Given data
borrowed = $2100
time = 15 months
rate = 2.6%
to find out
interest and receive from the bank and actual rate of interest
solution
we know bank discounted the loan at 2.6%
so interest will be 2.6% of $2100
that is = 2.6/100 × 2100
interest = $54.60
so receive from the bank is borrowed money - interest
receive = 2100 - 54.60
receive from the bank is $2045.40
and we can say that interest is directly proportional to time
so interest of 12 months / interest of 15 month = 12 month time/ 15 month time
here interest of 12 months = 12/15 × interest of 15 month
interest of 12 months = 12/15 × 54.60
interest of 12 months is $43.68 (annually)
now we can calculate actual rate of interest
that is = interest / borrowed money × 100
actual rate of interest = 43.68/2100 × 100
actual rate of interest is 2.08 %
Answer:
a. yes
b. no
c. yes
d. yes
Step-by-step explanation:
For a, 27 + 38 can be broken apart. 27 is broken up by adding smaller numbers (20 + 7 = 27) and the same is done with 38 (30 + 8 = 38), so A and C shows a way to add 27 and 38. In C, the numbers are just put into a different order. B is not a way to add 27 and 38, because the sum is different.
27 + 38 = 65, however 20 + 70 + 38 = 128. The addition problem for D is a way to solve for 27 + 38, because it is broken up differently than A and C. They instead added the 20 and 30 together first, then split up 15 (from 8+7) into 10 and 5. So D is a way to solve, because it gets the same answer as 27 and 38 :D
Answer:
y- intercept --> Location on graph where input is zero
f(x) < 0 --> Intervals of the domain where the graph is below the x-axis
x- intercept --> Location on graph where output is zero
f(x) > 0 --> Intervals of the domain where the graph is above the x-axis
Step-by-step explanation:
Y-intercept: The y-intercept is equivalent to the point where x= 0. 'x' is the input variable in an equation, therefore the y-intercept is where the input, or x, is equal to 0.
f(x) <0: Notice the 'lesser than' sign. This means that the value of f(x), or 'y', is less than 0. This means that this area consists of intervals of the domain below the x-axis.
X-intercept: The x-intercept is the location of the graph where y= 0, or the output is equal to 0.
f(x) >0: In this, there is a 'greater than' sign. This means that f(x), or 'y', is greater than 0. Therefore, this consists of intervals of the domain above the x-axis.
Zero.
Anything times zero is zero.
-20 * -10 = 200
200 * -1 = -200
-200 * 0 = 0
