Answer:
x=2, y=0
Step-by-step explanation:
The correct answer is C. The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground.
Explanation:
Two key features of living organisms are energy processing and response to stimuli. These two features imply organisms require nutrients, which can be taken from the environment or created through a process such as photosynthesis and they sense their surroundings and respond to it.
Moreover, these two features are exemplified by mushroom (fungi) in the sentence "The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground" because the first section shows the developing mushroom takes nutrients from the soil or its environment and this is essential for growing and survival. Also, the second section of the sentence shows the developing mushroom can sense its environment and respond by developing only in appropriate conditions.
Answer:
x^2 +23x +49
Step-by-step explanation:
First we find the area of the rectangle as though the small square were not cut out of it
A = (x+10) (2x+5)
Foil
2x^2 +5x+20x+50
2x^2 +25x+50
Then we find the area of the small square
A = (x+1) (x+1)
FOIL
x^2 +x+x+1
x^2 +2x+1
Then we subtract the small square from the large rectangle to find the area of the shaded region
2x^2 +25x+50 - (x^2 +2x+1)
Distribute the minus sign
2x^2 +25x+50 - x^2 -2x-1
x^2 +23x +49
The major trigonometric ratios at this level include sine, cosine and tangent.
sine is the ratio of opposite to hypotenuse, cosine is the ratio of adjacent to hypotenuse while tan is the ratio of opposite to adjacent. Therefore, in this case our adjacent is 15, To get the hypotenuse we use the pythagoras theorem
15² + 9² = 346, thus the hypotenuse will be √346.
Hence, cos B will be 15/√346
<span> the total distance around the pie is the circumference of the pie, assuming that the pie is a perfect circle then the formula for the circumference of a circle is:
c = piD
where pi is equal to 3.1416
D is the diameter of pie or circle
substitute the given values
C = (3.1416) ( 20 ft
c = 62.832 ft
