Answer:
$1,105.69
Explanation:
For this question we use the Present value formula that is shown on the attachment. Kindly find it below:
Given that,
Future value = $1,000
Rate of interest = 8.4% ÷ 2 = 4.2%
NPER = 20 years × 2 = 40 years
PMT = $1,000 × 9.5% ÷ 2 = $47.50
The formula is shown below:
= -PV(Rate;NPER;PMT;FV;type)
So, after solving this, the maximum price pay for the bond is $1,105.69
Answer:
6650km
Explanation:
Distance = (6.4 × 10³ + 250) km
= 6650 km
Answer:
graph 1
Explanation:
When it comes to a graph showing "constant acceleration," the line should be straight and upward <em>(positive acceleration) or </em>straight and downward <em>(negative acceleration).</em> The variables for acceleration are time and velocity. The independent variable (time) should be placed on the<em> x-axis</em> while the dependent variable (velocity) should be placed on the<em> y-axis.</em> As time increases, the velocity increases the same way. It doesn't slow down or changes. This makes it constant. <u>They are also directly proportional to each other</u>. This is evident on the first graph.
