The rule is n + 5

So we have that

an = n + 5

Where n is the term, that said we want the 1st, 2nd, 3rd, 4th and 10th term

a1 = 1 + 5 = 6

a2 = 2 + 5 = 7

a3 = 3 + 5 = 8

a4 = 4 + 5 = 9

a10 = 10 + 5 = 15

What is the 4th term in the sequence? <br><br> C(1)=56<br> C(n)= c(n-1)•1/2
Anton [14]

Answer:

The 4th term is 7

Step-by-step explanation:

we have

C(n)=C(n-1)\frac{1}{2}

C(1)=56

step 1

Find C(2)

For n=2

C(2)=C(1)\frac{1}{2}

C(2)=(56)\frac{1}{2}=28

step 2

Find C(3)

For n=3

C(3)=C(2)\frac{1}{2}

C(3)=(28)\frac{1}{2}=14

step 3

Find C(4)

For n=4

C(4)=C(3)\frac{1}{2}

C(4)=(14)\frac{1}{2}=7

therefore

The 4th term is 7

The volume V of a rectangular pyramid varies jointly as the area of the base B and the height h. V = 56 m3, when B = 24 m2 and h
Tasya [4]

Answer: B=27 m²

Step-by-step explanation:

Based on the information in the problem, if the volume V of a rectangular pyramid varies jointly as the area of the base B and the height h, you can write the following equation:

V=kBh

Where k is a constant.

You can calculate k as following:

56m^{3}=k*24m^{2}*7m

When you solve for k you obtain:

k=\frac{1}{3}

Then, when V=81 m³ and h=9m m, B is:

V=kBh\\B=\frac{V}{kh}\\B=\frac{81m^{3}}{\frac{1}{3}*9m}\\B=27m^{2}

Find three positive numbers whose sum is 100 and whose product is a maximum.
matrenka [14]

Answer:

The numbers are;

x = 100/3,  y = 100/3,  z = 100/3

Step-by-step explanation:

Given the data in the question;

so let the numbers be; x , y and z

so

x + y + z = 100

now

G(x,y,z) = x + y + z - 100

F(x,y,z) = xyz

Fx = yz, Gx = 1

Fy = xz, Gy = 1

Fz = xy, Gz = 1

Fx = λ × Gx

yz = λ

Similarly, xz = lambda

And xy = lambda

From above clearly, x = y = z

x + y + z = 100

so

3x = 100

x = 100/3

since, x = y = z therefore, each number is equal to 100/3

x = 100/3,  y = 100/3,  z = 100/3
