the total surface area of a hemisphere is 45
[tex]\pi\p[/tex]
CM square find its volume
Answer:
The volume of the hemisphere
V = 121.33086 cubic centimeter
Step-by-step explanation:
Step(i):-
Given that the total surface area of a hemisphere = 45π cm²
The total surface area of a hemisphere = 3π r²
Equating
3π r² = 45π
[tex]r^{2} = \frac{45}{3} =15[/tex]
r = [tex]\sqrt{15} = 3.87[/tex]
The radius of the sphere 'r' = 3.87
Step(ii):-
The volume of the hemisphere
[tex]V = \frac{2}{3} \pi r^{3}[/tex]
[tex]V = \frac{2}{3} \pi (3.87)^{3}[/tex]
we know that π = 3.14
[tex]V = \frac{2}{3} (3.14) (3.87)^{3}[/tex]
V = 121.33086 cubic centimeter

A 254-foot tall radio tower is located partway between a building and a tree. The angle of elevation from the base of the building to the top of the tower is 36°, and the angle of elevation from the base of the tree to the top of the tower is 62°.
Answer: here's your answer
485 ft
Step-by-step explanation:
step 1
Find the distance from the base of the building to the base of the radio tower
Let
x -----> the distance from the base of the building to the base of the radio
we know that
tan(36°)=254/x
x=254/tan(36°)=349.60 ft
step 2
Find the distance from the base of the tree to the base of the radio tower
Let
x -----> the distance from the base of the tree to the base of the radio tower
we know that
tan(62°)=254/x
x=254/tan(62°)=135.05 ft
step 3
Find the distance from the base of the building to the base of the tree
Adds the distances
349.60 ft+135.05 ft=484.65 ft
Round to the nearest foot
484.65 ft=485 ft

Answer:
f(x)= -2|x-3|-1
(Hi Simran! I just wanted to help you with this question though it might be wrong)
Step-by-step explanation:
f(x) = a|x-h|+k
f(x)= a|x-3|-1
-7 = a |0-3| -1
-7 = a |-3| -1 <-- add to -7
-6 = a |-3|
-6 = 3a
-6/3 = a
-2 = a
-------------------------------------------------------------------------------------
The equation of the absolute value is f(x)= -2|x-3|-1
The graph of y = f(x) is graphed below. What is the end behavior of f(x)?
Answer:
A
Step-by-step explanation:
As the graphs goes really far to the left or really far to the right you can see that the Y value is only going up

Answer:
A. 200
B. Growth
C. 118%
Step-by-step explanation:
Answer:
Initial population size=200
The function represents a growth
Step-by-step explanation:
Equation to calculate population size after time, t
P(t) = 200(1.18)^t
To find initial population size we will take t = 0
P(0) = 200(1.18)^0
= 200(1)
= 200
To find that function represent growth or decay
P(1) = 200(1.18)^1
= 200(1.18)
= 236
Its means that after a year population increases. Hence, function represent growth.
By what percentage does the population change each year?
(236 - 200 / 200) * 100%
= 235%
Order these numbers from least to greatest.

LITTERLY HELP ME PLEASEE..... 2/x-4x/2x-3=-2
PLEASEE I INSERTED A PIC
Answer:
x = -3
Step-by-step explanation:
Given expression is,
[tex]\frac{2}{x}- \frac{4x}{2x-3}=-2[/tex]
[tex]\frac{2(2x-3)}{x(2x-3)}-\frac{4x(x)}{x(2x-3)}=-2[/tex]
[tex]\frac{2(2x-3)-4x^{2} }{x(2x-3)}=-2[/tex]
(4x - 6) - 4x² = -2x(2x - 3)
4x - 6 - 4x² = -4x² + 6x
4x - 6 = 6x
6x - 4x = -6
2x = -6
x = -3

Need help finding the value of x
Answer:
The value of x is 26.
Step-by-step explanation:
In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°
2x + 3x + 50 = 180
5x + 50 = 180
5x = 180 - 50
5x = 130
x = 130 ÷ 5
x = 26
As we know that,
Sum of all angles of triangle = 180°
Given,
Angles are 2x , 3x and 50°
Now,
[tex] \rightarrow \: 2x + 3x + 50 = 180[/tex]
When plus sign goes to another side then,it become minus.
[tex] \rightarrow \: 5x = 180 - 50[/tex]
[tex] \rightarrow \: 5x = 130[/tex]
[tex] \rightarrow \: x = \cancel \dfrac{130}{5} [/tex]
[tex] \rightarrow \: x = 26[/tex]
Hence,the value of x is 26°.
