Answer:

(a) 8P3 =336;

25 = a1(1- (0.6)⁴)/(1-0.6)

25 = a1 (1- 0.13)/(0.4)

10 = a1(0.87)

a1 = 11.49

S8 = 11.49(1- (0.6)^8)/(1-0.6)

= 11.49(1-0.017)(1-0.6)

= 11.49(0.983)/0.4

= 28.24

The sum of the first eight terms of the given geometric series is; 28.24

We are told that the sum of the first four terms of the geometric series is 25. Thus, formula for sum of n terms of a geometric series is;

Sₙ = a(1 - rⁿ)/(1 - r)

where;

a is first term

r is common ratio

Thus;

25 = a(1 - (0.6)⁴)/(1 - 0.6)

25 = a(1 - 0.13)/(0.4)

10 = 0.87a

a = 11.49

Thus, sum of the first 8 terms of the series is;

S₈ = 11.49(1 - 0.6⁸)/(1 - 0.6)

S₈ = 11.49(1 - 0.017)(1 - 0.6)

S₈ = 28.24

Step-by-step explanation:

[tex]\sf\purple{The\:radius\:of\:the\:cylinder\:is\:approximately \:28 \:ft.}[/tex]

[tex]\sf\blue{Height\:of\:the\:cylinder\:(h) }[/tex] = 10 ft.

Answer:

7+√5/4

Step-by-step explanation:

if that is = a, find the value of a + 1 over a

​Given that a = 3 - √5

a+1/1 = (3-√5)+1/3 - √5

4-√5/3 - √5

Rationalize

4-√5/3 - √5 * 3+√5/3 + √5

= 12 +4√5-3√5-√25/9-5

= 12+√5-5/4

= 7+√5/4

Hence the requred answer is  7+√5/4

To find:

The solutions of the given equation.

Solution:

We have,

[tex]x^2+x-30=0[/tex]

Splitting the middle term, we get

[tex]x^2+6x-5x-30=0[/tex]

[tex]x(x+6)-5(x+6)=0[/tex]

[tex](x+6)(x-5)=0[/tex]

[tex]x=-6[/tex] and [tex]x=5[/tex]

Therefore, the solutions of the given quadratic equation are -6 and 5.

Answer: 12 boys attend Millwood School.

Step-by-step explanation:

Yeah. It just makes sense. I am bad at explaining. Sorry!

The ratio shows how many times one value is contained in another value.

The ratio of boys to girls at the Milwood School is 4 to 5.

The number of girls that attended the Milwood school is 15.

The number of boys that attended the Milwood school is 12.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

The ratio of boys to girls at the Milwood School is 4 to 5.

Total number of children = 27

Let the number of boys = 4x

Let the number of girls = 5x

Now,

4x + 5x = 27

9x = 27

x = 3

Now,

The number of boys = 4x = 4 x 3 = 12

The number of girls = 5x = 5 x 3 = 15

Thus,

The number of boys that attended the Milwood school is 12.

Answer:

B.  (3, ∞)

Step-by-step explanation:

Look at the graph of function f(x) = e^x.

The range is from 0, 0 not included, to infinity, or, in interval notation, (0, ∞).

The function g(x) = f(x) + 3 is the same as g(x) = e^x + 3.

g(x) is the the function f(x) shifted 3 units up.

That makes the range of g(x) from 3, 3 not included, to infinity.

Range: (3, ∞)

Answer:

Centre: [tex](\frac{1}{2} ,2)[/tex]

Radius = [tex]2[/tex]

Step-by-step explanation:

General formula for a circle: [tex](x-a)^2+(y-b)^2=r^2[/tex], where [tex]r=[/tex] the radius of the circle and [tex](a,b)[/tex] is the centre of the circle.

To find the centre and radius of the circle we should re-write the given equation in the form of the general formula.

So, put the terms with the same variables together:

[tex]4x^2-4x+4y^2+16y+1=0[/tex]

We can see that there is a common factor of [tex]4[/tex], so let's simplify by dividing by [tex]4[/tex]:

[tex]x^2-x+y^2+4y+\frac{1}{4} =0[/tex]

Here we can get it into the general formula by completing the square.

We do this by turning a quadratic with form [tex]ax^2+bx+c=0[/tex] into the form [tex](x-d)^2-e+c=0[/tex], where d is half of the coefficient of [tex]x[/tex], e is [tex]d^2[/tex] and c is the constant of the quadratic.

So let's re-write the equation of the circle:

[tex](x-\frac{1}{2} )^2-\frac{1}{4} +(y-2)^2-4+\frac{1}{4} =0[/tex]

Simplify: [tex](x-\frac{1}{2} )^2 +(y-2)^2-4} =0[/tex]

Now we can see that it's very similar to the general equation and all we have to do is bring the [tex]4[/tex] over to the right side.

[tex](x-\frac{1}{2} )^2 +(y-2)^2} =4[/tex]

So, now we can find the radius and centre.

[tex](a,b) = (\frac{1}{2} ,2)[/tex]

Answer:

226.19 [tex]cm^{3}[/tex]

Step-by-step explanation:

Vol. of cone = Bh/3   where B is the area of the base(circle) and h is the height of the cone.

r = 3   h = 3

V = [tex]\frac{\pi *3^{2}*3 }{3}[/tex] = 9π

Vol. of the cylinder = Bh   where B is the base(circle) and h is the height of the cylinder.

r = 3   h = 10 - 3 = 7

V = [tex]\pi *3^{2} * 7[/tex] = 63π

Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19

Volume is a three-dimensional scalar quantity. The volume of the composite figure will be 226.194cm³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the composite solid is the sum of the slanted cylinder and the cone. Therefore, the volume will be,

Volume = Volume of cone + Volume of slant cylinder

             = [(1/3)πr²h] + [πr²H]

             = [(1/3)×π×(3)²×3] + [π×(3)²×7]

             = 28.274 cm³ + 197.920 cm³

             = 226.194 cm³

Hence, the volume of the composite figure will be 226.194cm³.
