In computer technology, a kilobyte is 2^10 bytes in size. A gigabyte is 2^30 bytes in size. The size of a terabyte is the product of the size of a kilobyte and the size of a gigabyte. What is the size of a terabyte?
Answer:
The type of a terabyte is 2⁴⁰
Step-by-step explanation:
Given in the question ;
A kilobyte is 2¹⁰ bytes in size.
A gigabyte is 2³⁰ bytes in size.
The size of a terabyte is the product of the two given above.
Apply the laws of indices where you perform product and the base is the same, you add the powers and maintain the base as;
=2¹⁰ ₓ 2³⁰ = 2⁽¹⁰⁺³⁰⁾
=2⁴⁰

39 - 12w =7- 16w
iIl give a brainliest
Answer:
w=-8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
39−12w=7−16w
39+−12w=7+−16w
−12w+39=−16w+7
Step 2: Add 16w to both sides.
−12w+39+16w=−16w+7+16w
4w+39=7
Step 3: Subtract 39 from both sides.
4w+39−39=7−39
4w=−32
Step 4: Divide both sides by 4.
4w/4=-32/4

Answer:
How do you multiply 18 by 5/6? Here we will show you step-by-step how to solve 18 times 5/6, which can be written as follows:
18
x
5
6
Step 1: Setup
First of all, note that 18 is the same as 18/1 since 18 divided by 1 is 18. Therefore, start by setting up the problem like this:
18
1
x
5
6
Step 2: Multiply
Multiply the numerators together (18 x 5 = 90) and multiply the denominators together (1 x 6 = 6) and make it into one fraction like so:
90
6
Step 3: Minimize
The greatest common factor of 90 and 6 is 6. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
15
1
Step 4: Convert
Convert the improper fraction above to a whole number to get the answer:
15
That's it! Now you know how to calculate 18 times 5/6.
Answer:
15
Step-by-step explanation:
First turn the 18 into a fraction: 18/1
Next put the two fractions into an equation: 5/6 x 18/1 = ?
Then we mutiply the top numbers and the bottom numbers: 90/6
Finally since the fraction is top heavy, we divide to make it eithera lower fraction or a full number: 90/6 = 15
Your final answer will be 15 :)

Answer: E. (x+5)^2 + (y-5)^2 = 9
Step-by-step explanation:
The equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.
We are given that the center is (-5,5), which means that h = -5 and k = 5.
We are also given that the radius (r) = 3, which means r^2 = 9.
Therefore, the equation should be (x-(-5))^2 + (y-5)^2 = 9.
--> (x+5)^2 + (y-5)^2 = 9

Step-by-step explanation:
Given :-
sin² a/2 - sin a/2 + 1/4
To find :-
a
Solving :-
sin² a/2 - sin a/2 + 1/4 = (sin a/2 - 1/2)² = 0
