Use the formula A=p(1+r)^n
where
A= value of investment
r= rate
n= time period
p= amount invested
in this question
r= 5.75% but compounded quarterly means divide this by 4
r= 23/1600
n=7*4
n=28
p= $1200
A=1200(1+23/1600)^28
A= $1789.54
Therefore the value of her investment in 7 years is $1789.54
Answer:
Step-by-step explanation:
A(3, - 2), B(1, 5), C(1, - 2)
ΔABC is right angled Δ
AC and BC are legs (cathetus)
= (AC)(BC) ÷ 2 = 
= 7 units²
Answer:

a) The method of study;
i) Through visual information only
ii) Using auditory information only
iii) Not studying at all
b) The duration of study
Four days
c) The number of questions in the exam

Step-by-step explanation:
Dependent Variable
The dependent variable is the measured result of the experiment which are the values that change due to a change in the treatment applied in the experiment
The dependent variable is the output of the function of the experiment from an varied inputs to the experiment which is the independent variable
Independent Variable
The independent variable are the variable taken as the cause of the desired effect which is observed measured as the dependent variable
Answer:
The correct answer is option B.
(4x + 8)/(5x - 5)
Step-by-step explanation:
It is given an expression in variable x
2x/(x - 1) ÷ 5x/(2x + 4)
<u>To find the correct option</u>
2x/(x - 1) ÷ 5x(2x + 4) = 2x/(x - 1) * (2x + 4)/5x
= 2x/(x - 1) * 2(x +2)/5x
= [2x * 2 * (x + 2)]/[(x - 1)5x]
= 4(x +2)/5(x - 1)
= 4x + 8)/(5x - 5)
The correct answer is option B.
(4x + 8)/(5x - 5)
