[tex]\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{5 \: m}}\put(9,17.5){\sf{12 \: m}}\end{picture}[/tex]

Solution :-

As per provided information in the given question, we have been given that the Radius of a cylinder is 5 meters. The height of a cylinder is 12 meters. We have been asked to find the volume of a cylinder.

To calculate the volume of a cylinder, we will apply the formula below :-

[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: Volume_{(Cylinder)} = \pi r^2 h \: \: }}[/tex]

Substitute the given values into the above formula and solve for Volume :-

[tex]\sf:\implies Volume_{(Cylinder)} = \pi r^2 h[/tex]

[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(5 \: m)^2(12 \: m)[/tex]

[tex]\sf:\implies Volume_{(Cylinder)} = (3.14)(25 \:m^2)(12 \: m)[/tex]

[tex]\sf:\implies Volume_{(Cylinder)} = (78.5 \:m^2)(12 \:m)[/tex]

[tex]\sf:\implies\bold{Volume_{(Cylinder)} = 942 \: m^3}[/tex]

Therefore :-

Answer:

these are tough,   it takes a lot of practice to get used to these, sooo

Step-by-step explanation:

we know the slope, m= -5/3,   and we're given a point so use the point slope formula

y= mx + b

the point we are given is in this form  (x,y)

then plug the information into our point slope formula

y = (-5/3) x  + (-2)

y = -5x/3 -2

Answer:

Sometimes

Step-by-step explanation:

Example 1:

Take two numbers as [tex]7,8[/tex]

LCM of [tex]7,8=7(8)=56[/tex]

In this case, the lcm of two numbers is equal to the product of the two numbers.

Example 2:

Take two numbers as [tex]6,3[/tex]

[tex]6=3(2)[/tex]

So,

LCM of [tex]6,3=3(2)=6[/tex]

In this case, the lcm of two numbers is not equal to the product of the two numbers.

Therefore,

Sometimes, the lcm of two numbers is equal to the product of the two numbers.

Answer:

  30√3 m ≈ 52 m

Step-by-step explanation:

The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. The long leg of the triangle is √3 times 30 m, or about 51.96 m.

The distance between the tree and the tower is about 30√3 m ≈ 52 m.

__

If you haven't memorized the ratios of this special triangle, you can use the relation ...

  Tan = Opposite/Adjacent

  tan(30°) = 30/d

  d = 30/tan(30°) = 30√3 = 51.96 . . . . same as above

Im not for sure.. but I think it would be something like 3,9

Answer:

We rearrange the first equation into y = 8x - 42 and we substitute it in to get

-4x - 6 = 8x - 42 so 12x = 36 so

x = 3 and y = -18

Answer:

20 yd²

Step-by-step explanation:

lets do the big one

4 x (6-2) = 4 x 4 = 16 yd²

2 x (4-2) = 2x2 = 4 yd²

16 yd² + 4 yd² = 20 yd²

Another way

Find the area of the figure if it was a rectangle

4 x 6 = 24 yd²

then subtract 2 x 2 = 24 yd² - 4 yd² = 20 yd²

Answer:

20

Step-by-step explanation:

Solve the area of the squares separately, then add. the small square has a length and width of 2, and 2x2 is 4, so that area is 4. the bigger one has a length and width of 4, and 4x4 is 16, and then we add the two values together, and 16+4 is 20, so the total area is 20.

Answer: x=7 y=-8

Step-by-step explanation:

Answer:

function b

Step-by-step explanation:

When its asking for which function has a greater rate of change its asking for which slope has a greater value

the slope is calculated by change in y over change in x

for function a, as y goes up 2 x goes up 1

so the slope ( rate of change) is 2/1

for function b is y goes up 3 x goes up 1

so the slope (rate of change) is 3/1

3/1 is greater than 2/1 so function b has a greater rate of change

Answer:

3.7

Step-by-step explanation:

Answer:

a) 5/8

Step-by-step explanation:

f(-3) when f(x)=5(2)^x just replace the x with -3

f(x)=5(2)^x = 5 (2)^-3 we find the 3rd power of 2 first which means multiply 2 with itself 3 times

2×2×2 = 8 but here, it asks us for negative third power of 2 so we turn the 8 upside down :

if 2^3 = 8 then 2^-3 = 1/8 and now we multiply it with 5

5 × 1/8 = 5/8

Step-by-step explanation:

Answer:

(x, y) = (8, -2)

Step-by-step explanation:

Substitute:
