Answer:

a) Lateral surface area = 1225.2 m²

b) Total surface area = 1756.2 m²

Step-by-step explanation:

We are to find the Lateral and Total surface area of the cone in the diagram

Slant height = l = 30m

Diameter = 26 m

Radius = Diameter /2 = 26m/2 = 13m

a) The Lateral surface area of a cone when given the slant height is calculated as:

πr × l

= π × 13 × 30

= π × 13 × 43

= 1225.2211349 m²

Approximately = 1225.2 m²

b) The Total Surface area of the cone when given the slant height is calculated as:

πr( r + l)

= π × 13 × (13 + 30)

= π × 13 × 43

= 1756.1502934 m²

Approximately = 1756.2 m²

Answer:

x^2 - 9

Step-by-step explanation:

The square root of the quadratic equation [tex](x^2 -6x+ 9)[/tex] if x<-3 would be equal to (x-3).

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

The given quadratic equation is

[tex](x^2 -6x+ 9)[/tex]

We have to find the square root of the quadratic equation

[tex]\sqrt{(x^2 -6x+ 9)} \\\\\sqrt{(x^2 -3x-3x+ 9)} \\\\\sqrt{x(x-3)-3 (x-3)} \\\\\sqrt{(x-3) (x-3)} \\\\\sqrt{(x-3)^2} \\\\(x-3)[/tex]

Thus, the square root of the quadratic equation [tex](x^2 -6x+ 9)[/tex] if x<-3 would be equal to (x-3).

Answer:

10 feet

Step-by-step explanation:

Perimeter of rectangle = 2l+2b

Area of the rectangle = l x b

Area of the rectangle = 4 square feet

possible factors of 4 = 2x2/4x1

So sides of the rectangle are 4 & 1 as 2&2 would make it a square

So perimeter= 2x4+2x1

= 8+2

Answer:

P(A) = 0.62

P(B) = 0.5

Step-by-step explanation:

Given the following

P(A or B) = 0.96

P(A and B) = 0.16

P( A | B ) = 0.32

According to conditional probability

P( A | B ) = P(A and B) /P(B)

0.32 = 0.16/P(B)

P(B)= 0.16/0.32

P(B)= 0.5

P(A or B)  = p(A) + p(B) – p(A and B)

Substitute the given values

0.96 = P(A)+ 0.5 - 0.16

P(A) = 0.96 - 0.5 + 0.16

P(A) = 0.62

The value of [tex]P(A)\\[/tex] is [tex]0.62[/tex]  and the value of [tex]P(B)[/tex] is   [tex]0.5[/tex]     .

The possibility of a random event to occur is called probability. It lies between the range of [tex]1[/tex] and [tex]0[/tex].

Given data:

[tex]P(A or B) = 0.96[/tex]

[tex]P(A and B) = 0.16[/tex]

[tex]P( A | B ) = 0.32[/tex]

According to the conditional probability definition,

The occurrence of an event or event that occurs as a result of previous events or events is called conditional probability.

[tex]P( A | B ) = \dfrac{P(A and B)} {P(B)}[/tex]

[tex]0.32 = \dfrac{0.16}{P(B)}[/tex]

[tex]P(B)= \dfrac{0.16}{0.32}[/tex]

[tex]P(B)= 0.5[/tex]

[tex]P(A or B) = p(A) + p(B) - p(A\ and \ B)[/tex]

Substitute the given values in the given relation,

[tex]0.96 = P(A)+ 0.5 - 0.16[/tex]

[tex]P(A) = 0.96 - 0.5 + 0.16[/tex]

[tex]P(A) = 0.62[/tex]

Thus, the value of [tex]P(A) = 0.62[/tex]  and the value of  [tex]P(B)[/tex] is   [tex]0.5[/tex].

Answer:

127.1 m

Step-by-step explanation:

We are given the value of the adjacent side and we are to find the value of the opposite side

Tan would be used to determine this value

Tan 23 = opposite / adjacent

1.5882 = x / 80

x = 80 x 1.5882

x = 127.056 m

x = 127.1m

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Answer:

1) yes  2) no  3) yes

Step-by-step explanation:

The lengths of the two shorter sides must be greater than the length of the longest side.

1) 8 + 9 > 10    yes

2) 1 + 1 = 2      no

3)  6 + 8 > 9    yes

The lengths which can be side of triangle are:

Apply the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

1. 8, 9, 10:

The sum of the lengths of the two smaller sides is 8 + 9 = 17 > 10

Therefore, these numbers can be the lengths of the sides of a triangle.

2. 1, 1, 2:

The sum of the lengths of the two smaller sides is 1 + 1 = 2.

No, 2 is equal to the length of the longest side.

So these numbers cannot be the lengths of the sides of a triangle.

3. 6, 9, 8:

The sum of the lengths of the two smaller sides is 6 + 8 = 14 > 10

Therefore, these numbers can be the lengths of the sides of a triangle.

Answer:

28

Step-by-step explanation:

Since the perimeter is the width + width + length + length, we know that there 2 of the 8 millimeter width in the perimeter. So multiply 8 by 2, which is 16. So 16 of the 72 represents both widths. So subtract 16 from 72. You're left with 56, which represents 2 of the length. So divide 56 by 2, and you get one of the length, which is 28.

Answer:

If D = 0, then the quadratic equation has 1 solution x = − b/2a

Step-by-step explanation:

If we have a quadratic equation x² +3x-4= 0

Then the corresponding values of a= 1, b=3, c= -4

Finding the discriminant gives

D=  b2 - 4ac.

D= 3²- 4(1) (-4)

D= 9 + 16

D= 25  

Here a> 0

But if a< 0  e.g a= -1

D=  b2 - 4ac.

D= 3²- 4(-1) (-4)

D= 9 - 16

D= -7  

Here a < 0 so we get the answer -7  < 0

D=  b2 - 4ac.

D= 4²- 4(-1) (-4)

D= 16 - 16

D= 0  

Here a< 0 and b= - c so that D= 0

When D < 0 roots do not exist.

If D = 0, then the quadratic equation has 1 solution x = − b/2a

This can be found out by using the quadratic formula

x= -b±√b²- 4ac/ 2a

But D= 0

x= -b±0/ 2a

x= -b/2a
