Answer:
8
Step-by-step explanation:
(5 + 16) / 7 + 3^2 - (1 + 3)
21 / 7 + 3^2 - 4
21 / 7 + 9 - 4
3 + 9 - 4
12 - 4
8
Use PEMDAS.
P - Parenthesis
E - Exponents
M/D - Multiply/Divide
A/S - Add/subtract
So for this:
Start with parenthesis: (5+16) and (1+3), so 21 and 4
Then exponent: 3^2, which is 3*3 which is 9
Then divide: 21/7 is 3
And then the rest: 3 + 9 - 4. 3+9 is 12, 12-4 is 8, so you're answer is 8.

Answers
Answer:
2 units
Step-by-step explanation:
none
The radius of a circle with the given equation is 5 units.
Given the following data:
[tex]x^2+y^2+8x-6y+21=0[/tex]The equation of a circle.Mathematically, the standard form of the equation of a circle is given by;
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where;
h and k represents the coordinates at the center.r represents the radius of the circle.Expanding the equation, we have:
[tex]x^2+y^2-2hx-2ky+(h^2+k^2-r^2)=0\\\\r=\sqrt{h^2+k^2}[/tex]
Comparing the terms, we have:
-2hx = 8x
h = -4
-2ky = -6y
k = 3.
For the radius:
[tex]r=\sqrt{-4^2+3^2}\\\\r=\sqrt{16+9} \\\\r=\sqrt{25}[/tex]
r = 5 units.

238 divided by 11 equals 21 with a remainder of 7.
To divide 238 by 11 using long division, we follow these steps:
Set up the division: Write 238 as the dividend and 11 as the divisor. Place the dividend inside the long division symbol and the divisor outside of it.
Begin dividing: Divide the first digit of the dividend (2) by the divisor (11). The quotient is 0 since 2 is less than 11.
Bring down the next digit of the dividend (3) and place it after the 0. We now have 23.
Divide 23 by 11. The quotient is 2 as 11 goes into 23 two times.
Multiply the divisor (11) by the quotient (2) and subtract the result from 23:
23 - (11 x 2) = 23 - 22 = 1
Bring down the next digit of the dividend (8). We now have 18.
Divide 18 by 11. The quotient is 1 as 11 goes into 18 one time.
Multiply the divisor (11) by the quotient (1) and subtract the result from 18:
18 - (11 x 1) = 18 - 11 = 7
There is no more digit to bring down, so we have completed the division. The final remainder is 7.

WHAT DOES THIS MEAN GIMME THE ANSWER
Answers
Answer:
This is a geometric sequence and the ratio is equal to 4.
Step-by-step explanation:
Arithmetic means you can continue the sequence through addition or subtraction.
Geometric means you can continue the sequence through multiplication or division.
To get from 3 to 12, we could either add 9 (arithmetic) or multiply by 4 (geometric).
To get from 12 to 48, we could either add 36 or multiply by 4.
Since we are looking for a pattern, the sequence would be geometric. This is because the sequence can be continued by multiplying by 4 each time. It cannot be arithmetic because we cannot add by 9 each time.
On a side note, common difference is used when describing arithmetic while ratio is used to describe geometric.

How do I find the next four of the sequence?
Answers
Step-by-step explanation:
In this arithmetic sequence, the common difference d is 7. You can find this by subtracting a term from the consecutive term: 16 - 9 = 7, 23 - 16 = 7. In order to find the next four terms, keep adding 7 to the previous term. The next four terms are 30, 37, 44, and 51.
Answer:
Step-by-step explanation:
[tex]a_{1}[/tex] = [tex]\frac{3}{4}[/tex]
d = - [tex]\frac{1}{4}[/tex]
[tex]a_{2}[/tex] = [tex]\frac{3}{4}[/tex] + ( - [tex]\frac{1}{4}[/tex] ) = [tex]\frac{1}{2}[/tex]
[tex]a_{3}[/tex] = [tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex] = - [tex]\frac{1}{2}[/tex]
[tex]a_{4}[/tex] = - [tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex] = - [tex]\frac{3}{4}[/tex]
[tex]a_{5}[/tex] = - [tex]\frac{3}{4}[/tex] - [tex]\frac{1}{4}[/tex] = - 1
