Answer:
∠F = 42° to the nearest degree
Step-by-step explanation:
In this question, we are asked to calculate the value of the angle.
Kindly note that since one of the angles we are dealing with in the triangle is 90°, this means that the triangle is a right-angled triangle
Please check attachment for the diagrammatic representation of the triangle
From the diagram, we can identify that the EF is the hypotenuse and the length FG is the adjacent. Thus , the appropriate trigonometric identity to use is the cosine
mathematically;
Cosine of an angle = length of adjacent/length of hypotenuse
F = 42.07
∠F = 42° to the nearest degree
Answer: After 8 hours the pressure will be at -60?
Explanation: not sure how the balloon can reach -60 kilopascals but 15% of 300 is 45 and 45 x 8(hours) is 360. 300 - 360 is -60
Answer:
Step-by-step explanation:
The smallest zero is x=-7 with multiplicity of 1
The middle zero is x=2 with the multiplicity of 2
The largest zero is x=0 with the multiplicity of 7.
So, basically you just find the zero for each of the terms by setting em equal to 0 and then the multiplicty of it is the exponent for that particular term!
Hope this helps!
