Answer:
(d) 810.34
Step-by-step explanation:
The explicit formula used for calculating the account's balance is given by:
A= P(1+R)^T
where: A= Amount (account's balance)
P= Principal (700)
R= Rate (5%)
T= Time (3 years) [since, the balance is calculated in the beginning of the forth year]
A= P(1+R)^T
A = 700(1+0.05)^3
= 700(1.05)^3
= 700*1.157
= 810.34
Aₙ = 7n+4
n = 12 thus
a₁₂ = 7(12) + 4

Answer:
The point (1, 1) makes the inequality
true.
Step-by-step explanation:
Given inequality:
![2x+17y\geq 19](https://tex.z-dn.net/?f=2x%2B17y%5Cgeq%2019)
Point (1,1)
To check if the inequality is true for the given point.
Solution:
For a point
to make the inequality true it must lie within the inequality range, or in other words it must be a solution of the inequality.
To check if point (1,1) lies within the inequality range, we will plugin the
and
values of the point in the given inequality.
Plugging in
and
in the inequality.
![2(1)+17(1)\geq 19](https://tex.z-dn.net/?f=2%281%29%2B17%281%29%5Cgeq%2019)
![2+17\geq 19](https://tex.z-dn.net/?f=2%2B17%5Cgeq%2019)
![19\geq 19](https://tex.z-dn.net/?f=19%5Cgeq%2019)
Thus it satisfies the inequality as 19 is included in the inequality.
Thus, we say point (1, 1) makes the inequality
true.
The graph of the inequality
and the location of the point (1,1) is shown below.
