The area of the sector would be 196.3
Find the dot product of the vectors
a = <ax, ay> and b = <bx, by>
The dot product is found by multiplying corresponding coordinates, and then sum all those products:
a * b = ax * ay + bx * by
________
For this question, you have these vectors
a = <5, 2> and b = <4, 5>
so the dot product is
a * b = 5 * 4 + 2 * 5
a * b = 20 + 10
a * b = 30 <----- this is the answer.
I hope this helps. =)
To find the inverse of a function, stick a y for the f(x).
So, f(x) = 4x + 12 becomes y = 4x + 12
Then switch the x and y.
So, y = 4x + 12 becomes x = 4y + 12
Then solve for y.
x = 4y + 12
x - 4y = 12 <-- Subtract both sides by 4y
-4y = 12 - x <-- Subtract both sides by x
y =
![-3 + \frac{x}{4}](https://tex.z-dn.net/?f=-3%20%2B%20%5Cfrac%7Bx%7D%7B4%7D)
So, the inverse of f(x) is g(x) = -3 + x/4.
Answer: C) 297 in2
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a square pyramid (S) = 2 (length of the base) slant + length of the base ^2
S = 2bs + b^2
Replacing with the values given:
S = 2 (9) 12 + 9^2
S = 216 +81 = 297 square inches
