Answer:
13
Step-by-step explanation:
To find the determinant you subtract the the leading diagonal from the non-leading diagonal.
(4x-2)-(-7x3)
-8 - -21
NB A negative beside a negative gives you a positive number.
-8+21
=13
V = πr²h
288 = 3.14(r²)(9)
288 = 3.14(9r²)
288 = 28.26r²
28.26 28.26
10.19 ≈ r²
3.19 ≈ r
B = πr²
B = 3.14(3.19)²
B = 3.14(10.19)
B = 31.9966
Answer:
The function is "f(x) = 5*x"
Step-by-step explanation:
Everytime we add a number to the independent variable of a function, in this case x, there'll be a common factor between the variable and a pure number. To solve this problem we need to make "(x + 3)" appear. Since we have "f(x+3)" we need to first factor the common denominator. We have:
f(x + 3) = 5*(x + 3)
Therefore,
f(x) = 5*x
The x-coord. of the vertex is halfway between the given zeros. Here, it'd be halfway between x=3 and x=9, which comes out to x = 6 (answer).
