Answer:
Step-by-step explanation:
For this exercise you need to use an Inverse Trigonometric Function called "Arctangent".
By definition:
You must observe carefully the triangle PQR shown in the picture attached.
In this case you can identify that:
Therefore, knowing those values you can substitute them into , as following:
Finally, evaluating, you get that the measure of the angle R is the following:
Rounding to the nearest tenth:
Well, if I'm correct. The ratio of the to numbers from red to yellow would be 4:5. So the fraction is 4 over 5.
Answer:
a. ∀ x≤0 ∧ ∀ y ∈ IR + ∪ 0
b. ∀ x≤0 ∧ ∀ y ∈ IR -
c. ∀ x≤0 ∧ ∀ y -∞ → +∞
Step-by-step explanation:
P=4l ⇒ 28=4l ⇔ l=28/4 =7
A=l.l=7*7=49
As can be seen in the graph so that x is negative, it must be fulfilled that its values are located in the second and third quadrants and their values must be less than zero and also the values of y can be all positive and negative real numbers
Possible coordinates:
a. ∀ x≤0 ∧ ∀ y ∈ IR + ∪ 0
for all x less iqual than zero and all positive real y including zero
b. ∀ x≤0 ∧ ∀ y ∈ IR -
for all x less iqual than zero and all y negative reals
c. ∀ x≤0 ∧ ∀ y -∞ → +∞
for all x less equal than zero and all y from minus infinite to plus infinite
Answer:
It is 700 because it can't round up.
