Answer:

The area of a circle is [tex]\pir^{2}[\tex] and the radius is 4 so we have 16π and substituting 3.14 for pi we get 50.24 .

Hope this helps!

Answer: The fourth term is -102

----------------------------------------------

Explanation:

The term after the nth term is generated by this rule $a_{n+1} = -4(a_n) + 2$ which means that we first
Step 1) multiply the nth term ( $a_n$ ) by -4
Step 2) Add the result of step 1 to the value 2 to get the next term in the sequence

Let's follow those steps above to generate the first four terms

The first term is $a_1 = 2$ . In short, the first term is 2

The second term is...
$a_{n+1} = -4(a_n) + 2$
$a_{1+1} = -4(a_1) + 2$
$a_{2} = -4(2) + 2$
$a_{2} = -8 + 2$
$a_{2} = -6$
So the second term is -6

The third term is...
$a_{n+1} = -4(a_n) + 2$
$a_{2+1} = -4(a_2) + 2$
$a_{3} = -4(-6) + 2$
$a_{3} = 24 + 2$
$a_{3} = 26$
The third term is 26

Finally, the fourth term is...
$a_{n+1} = -4(a_n) + 2$
$a_{3+1} = -4(a_3) + 2$
$a_{4} = -4(26) + 2$
$a_{4} = -104 + 2$
$a_{4} = -102$
The fourth term is -102.

The price of an electronic puzzle was reduced be $7

Nimfa-mama [501]

Answer:

Step-by-step explanation:

total price was reduced by $ 7

let x = the total price........ x - 7

he bought 10.....and it cost him $ 130

10(x - 7) = 130

10x - 70 = 130

10x = 130 + 70

10x = 200

x = 200/10

x = 20 <====== original price

Can someone help me?

Ratling [72]

Answer:

135 ft²

Step-by-step explanation:

Heres a cool little trick! if you cut off one side straight down, take for example the triangle to the right, and take it over to the left side, it makes a square! so then you just have to multiply 9 by 15! Hope This Helps! :P

This question is worth 80 points can someone please check my answeres

Katen [24]

Answer/Step-by-step explanation:

#14. Correct

20ft x 28ft = 560 ft

560ft divided by 16 = 35ft

1.25in x 1.75in = 2.1875

2.1875in x 16 = 35ft

#9. Correct

20cm x 4 = 80cm

Btw this doesn't give us 80 points it gives us half of that = 40 points
