Step-by-step explanation:
for a it's y=12x+60
for b it's y=1x+21
for c it would be) 40-70=-30/1-3=-2 and then divide -30/-2 is 15.
for d it would be y=20x+20
it would be ethier a or d
Step-by-step explanation:
a. Pythagoras formula stated above
so 9²+12²
81+144 is 225
√252 is 15cm
b. in this question well have to use surds
an isosceles triangle had a 90 and 2x45 degree angles
we hypotenuse is 10cm
√a²+a² =10cm
√2a² is 10cm which makes
a√2 equals 10
then rearrange
a=10/√2= 5√2
the answer is 5√2
The future value of this amounts after 5 years in the order they will be recieved will be:
FV=p(1+r/100)^n
a. $7100
FV=7100(1+9/100)^5
FV=7100(1.09)^5
FV=$10,924.23
b.$8700
FV=8700(1+9/100)^5
FV=8700(1.09)^5
FV=$ 13,386.03
c. $12500
FV=12500(1+9/100)^5
FV=12500(1.09)^5
FV=$19,232.80
So she has 5/6 and 1/5. and they need to be split by 1/8 so do 5/6 divided by 1/5 and then do 4 1/6 divided by 1/8 to get
Answer:
Option (C) is correct .
Step-by-step explanation:
As the expression given in the question as follows.
Now rationalize the expression.
Using the formula
a² - b² = (a - b) (a + b)
Using in the above
As i² = -1
Option (C) is correct .
