Answer:
45%
Step-by-step explanation:
1/4 is 25/100 25+20 =45
65.
You simply have to put cos-1(sin(25))
Answer: The points are
(-1,2)
(0,1)
(1,2)
The graph is below
=========================================================
Explanation:
The idea is to replace x with the values mentioned (one at a time) and find the paired y value
For example, if x = -1, then...
y = x² + 1
y = (-1)² + 1
y = 1 + 1
y = 2
So (-1,2) is one point on the parabola. Follow similar steps to find the other points (0,1) and (1,2)
I used GeoGebra to make the graph shown below.
Answer:
25.75 % interest rate
Step-by-step explanation:
Given:
Amount was invested = r% per quarter
Amount invested = P
Rate of interest = r % per quarter
Time (n) = 4 Quarters
Computation:
A = P(1 + r/100)ⁿ
According to question.
⇒ A = P + 1.5P = 2.5P
⇒ 2.5P = P(1 + r/100)⁴
⇒ 2.5 = (1 + r/100)⁴
⇒ 1 + r/100 = 1.2575
⇒ r/100 = 0.2575
⇒ r = 25.75
25.75 % interest rate
