Answer:
3.4625
Step-by-step explanation:
Given the equation:
Q(t)=0.05t^2 + 0.1t + 3.4 parts per million
Where t = time in years
By approximately how much will the carbon monoxide lvel change during the coming 6 months?
t = 6 months = 6/12 = 0.5 year
Q(0.5) = 0.05(0.5)^2 + 0.1(0.5) + 3.4 parts per million
Q(0.5) = 0.05(0.25) + 0.05 + 3.4
Q(0.5) = 0.0125 + 0.05 + 3.4
Q = 3.4625
Carbon monoxide level will change by approximately 3.4625 parts per million in 6 months
Answer:
84°
Step-by-step explanation:
Let the two complementary angles be x and y.
If the measure of an angle is 14 times the other, then x = 14y...... 1
Since the two angles are complementary, their sum will be 90° i.e x+y = 90° ...... 2
Substitute equation 1 into 2
14y+y = 90
15y = 90
y = 90/15
y = 6
Since the angle is x = 14y
x = 14(6)
x = 84°
Hence the measure of the angle is 84°
The values of the variables x, y and z are; 9, 81 and 6 respectively
<h3>Rhombus Diagonals</h3>
According to the question;
- All sides of the Rhombus are equal.
Hence, the Diagonals of the Rhombus are perpendicular bisectors of each other.
Therefore,
Angles 1, 2 and 3 are all equal to 90°, so that we have;
x = 9°
y = 81°
z = 6°
