Step-by-step explanation:
You just have to find what the variable equals.
All these answers are correct
Answer:
10.3 years
Step-by-step explanation:
The Rule of 72 is a rule used to determine the period of time it would take an investment to double at a given fixed annual rate of return. The rule of 72 helps investors to have an estimate of how long an initial investment would double. The rule of 72 is given by the formula:
t = 72 / r
where r is the annual rate of return and t is the approximate time in years required for the investment to double.
t = 72 / r
Given that r = 7%
t = 72 / r = 72 / 7 = 10.3 years
Therefore it would take 10.3 years for an investment of $5,000 earning 7% annually to double to about $10,000
Answer:
The value of x = 5 and y = 2
The correct answer is last option
Step-by-step explanation:
From the figure we can see that, subtraction of two matrices.
The resultant matrix shows the corresponding terms difference.
<u>To find the value of x
</u>
1/2(x + 3) - (3*(-1)) = 7
x/2 + 3/2 +3 = 7
x/2 +3/2 = 7 - 3 = 4
x + 3 = 8
x = 8 - 3 = 5
x = 5
<u>To find the value of y
</u>
8/2 -3 (y +1) = -5
4 - 3(y +1)/ = -5
3(y +1) = 4 + 5 = 9
y + 1 = 9 / 3 = 3
y = 3 - 1 = 2
Therefore the value of x = 5 and y = 2
The correct answer is last option
Answer:
The last option : 3/2
Step-by-step explanation:
All the other ones would make 27/7n smaller.
Answer:
quadratic with a common second difference of 4
Step-by-step explanation:
quadratic equations: Quadratic equations are the polynomial equations of degree 2 example - a
+ b
+ c = 0.
from the table it is clear that,
function is y = 2
so the function is not linear as the equation specifies.
formula to find second difference of a quadratic equation:
f(x + 2) - 2f(x + 1) + f(x)
therefore;
- 
+ 
4
therefore, the answer is quadratic with a common second difference of 4
