Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

I can't do all these for you but I'll show you how they are done by taking some samples.

k) 2^x = 32

Take logs of both sides

log 2^x = log 32

x log 2 = log 32

x = log 32 / log 2   Using your calculator to find the log values:

x = 5.

r) 9^(x + 1) = 81

log 9^(x + 1) = log 81

x + 1 log 9 = log 81

x + 1 = log81 / log9 = 2

x + 1 = 2

x = 1.

The above method is a general way to do these using logs but with some of the simpler ones you don't have to use logs at all:

For example :

3^x = 27

We know that 3^3 is 27 so

3^x = 3^3  and so:

x = 3.

Step-by-step explanation:

The area of the larger rectangle is 10x (2x + 6) and the area of the swimming pool is 8(6x - 4). To find the area of the walkway we get:

10x(2x + 6) - 8(6x - 4)

= 20x² + 60x - 48x + 32

= 20x² + 12x + 32

Answer:

3126

Step-by-step explanation: f(1)=6 and f(n)=5f(n-1)-4. This means that next number is 5 times previous number minus 4.

f(2)=5f(1)-4 =5x6-4 = 30-4 = 26

f(3)=5f(2)-4 =5x26-4 = 130-4 = 126

f(4)=5f(3)-4 =5x126-4 = 630-4 = 626

f(5)=5f(4)-4 =5x626-4 = 3130-4 = 3126

The fifth term of the sequence is 4166

Given the recursive function expressed as;

f(n)=-5f(n-1)-4

If f(1 ) = 6

f(2) = -5f(1) - 4

f(2) = -5(6) - 4

f(2) = -30 - 4

f(2) = -34

If n = 3

f(3) = -5f(2) - 4

f(3) = -5(-34) - 4

f(3) = 170 - 4

f(3) = 166

If n = 4

f(4) = -5f(3) - 4

f(4) = -5(166) - 4

f(4) = -830 - 4

f(4) = -834

If n = 5

f(5) = -5f(4) - 4

f(5) = -5(-834) - 4

f(5) = 4170 - 4

f(5) = 4166

Hence the fifth term of the sequence is 4166

Step-by-step explanation:

1: shortest name 3 is the smallest number

2:  longest name is 9 letters nothing beats it

3: the graph shows those little like dot x things repersent the people with that length of name so 6 as the most therefore answer is 6

4: im guessing they mean which one is the middle of the graph so if it's middle depending on length of name it's 6, but if it's asking depending on number of people who have the name it's 3.

Answer: $124

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

8 x + 4 y = 176

3x + 15 y = 335

Cost = sum of products (number of fruits x price per unit)

Where x is the price per orange and y is the price per apple.

We have to multiply the first equation by 3 ; the second equation by 8; and subtract the first equation to the second:

24x +120y =2680

24 x +12y = 528

_______________

108y =2152

Solving for y

y = 2152/108

y= 20

Replacing y =20 in any equation:

8x + 4 (20)=176

8x+80=176

8x =176-80

8x =96

x =96/8

x=12

Finally we have to calculate how much would two oranges and five apples cost.

2x+5y = 2(12)+5(20)= 24+100= $124

Answer:

19

Step-by-step explanation:

If you order the Numbers from Least to Greatest

3,9,29,50

9 and 29 are in the middle

(29 +9) Divided by 2 is 19 so your median is 19

Answer: 19

Step-by-step explanation:

The first thing you have to do is order the numbers from least to greatest: 3, 9, 29, 50.

Next you have to find out which number is in the middle, but since there are an even set of numbers there will be 2 numbers in the middle. The 2 numbers in the middle would be 9 and 29.

The next step is to find the mean, or average of 9 and 29. To find the mean of something you have add all the numbers together and divide the sum by the amount of number there are. So we would have to add 9+29 which is 38, then we have to divide 38 by 2 since there are 2 numbers. 38 divided by 2 is 19.

So that means the median is 19.

Answer: B

Step-by-step explanation: I worked it out but have doubts

The length of each side of the square base is 35 meters, option B is correct.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The volume of the pyramid is 9,039

The height is of 21.6 meters.

We need to find the length of each side of the square base.

V=1/3b²h

9039=1/3×b²×21.6

9039=7.2b²

Divide both sides by 7.2

b²=1255.4

Take square root on both sides

b=35.4

b=35

Hence, the length of each side of the square base is 35 meters, option B is correct.
