Answer:
<h2>The answer is 4</h2>
Step-by-step explanation:
Step one:
given that the functions are
f(x)=√x+3,
g(x)=2x+9,
h(x)=x4 .
To Evaluate f(g(2)) , we need to find g(x=2)=2x+9,
substitute x=2 in g(x)=2x+9,
g(x=2)=2(2)+9,
g(x=2)=4+9,
g(x=2)=13
Step two:
now we can substitute g(x)= 13 in the function f(x)=√x+3
that is x=13
f(g(2)) =√g(x)+3--------g(x)=13
f(g(2)) =√13+3
f(g(2)) =√16
f(g(2)) =4
<u>Hence f(g(2)) is 4</u>
The ratio of cos Z is cos Z = 3 / 5
<h3>How to find the trigonometric ratios of a right triangle?</h3>
A right triangle has one angle of the triangle as 90 degrees.
The sides of the right triangle can be found using trigonometric ratios.
Therefore,
sin ∅ = opposite / hypotenuse
sin Z = 3 / 5
Using Pythagoras theorem,
c² = a² + b²
5² - 3² = b²
b² = 25 - 9
b² = 16
b = √16
b = 4
Hence,
P + A = 90 degrees (complementary angles)
Therefore,
sin P = cos Z
cos Z = 3 / 5

Answer:
30
Step-by-step explanation:
15/3=5
5 x 5 = 25
25 + 5 = 30
Answer:
Below.
Step-by-step explanation:
To find the volume of the silo find the volum of the hemisphere with radius of 15 feet and add the volume of the cylinder with a radius of 15 feet and a height of (100 - 15) = 85 feet.
The total volume = 1/2 * 4/3 π (15)^3 + π (15)^2 * 85
= 67151.5 ft^3.
huh? this does not make sense
