Answer:
The area of the pizza with a diameter of 18 inches is 254.34 inches.
Step-by-step explanation:
The formula to find the area of a cirlce is A = pi x r^2 or pi times radius squared.
Second, we need to find our radius. To find the radius we need to divide the diameter by 2 to get the radius. In this case; 18 divided by 2 is 9.
Then, we need to plug the radius in the formula:
A = 3.14 x 9^2
9 squared or 9 times 9 equals 81
Next, multiply 81 by 3.14 and you get 254.34
Lastly, add the units of measurement, which would be inches.
Answer:
Neither
Step-by-step explanation:
To be parallel the lines have to have the same slope. In this case the slopes are not the same.
To be perpendicular, the lines have to have negative reciprocal slopes.
For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.
So, the lines are no parallel and no perpendicular.
Answer:
A. x = -5/6 and x = 1/2.
Step-by-step explanation:
12x^2 + 4x - 5 = 0
Use the 'ac' method to try to factor this:
Consider the above highlighted numbers:
12 * -5 = -60.
Now we need 2 numbers whose product is -60 and whose sum is +4.
They are -6 and +10, so we replace the + 4x by -6x + 10x:
12x^2 - 6x + 10x - 5 = 0 Now factor by grouping:
6x(2x - 2) + 5(2x - 1) = 0 The 2x -1 is common, so:
(6x + 5)(2x - 1) = 0
So x = -5/6 and x = 1/2.
