Answer:
58
Step-by-step explanation:
you have 2 2 by 2 squares and 1 5 by 10 rectangle
To solve this problem, plugin 145 where the y is located and then solve for x
y = -27x +577
145 = -27x +577
145 -577 = -27x
-432 = -27x
-432/-27 = -27x/-27
16 = x
x = 16
After 16 weeks she will have $145 dollars in her account.
Answer:
It is an exponential function.
Initial value is - 1.8 and the base is 6.
Step-by-step explanation:
The function is given by 
and it is an exponential function as the general form of an exponential function is 
.
Here, if we put x = 0, the function becomes 
.
Therefore, the initial value of the function is - 1.8.
In the general equation of exponential function , b is called the base and x is the exponent.
Therefore, in our case the base of the function is 6. (Answer)
Answer:
a couple of irrational numbers: -16±4√19, approximately {1.436, -33.436}
Step-by-step explanation:
Your question can be cast as the quadratic equation
x² +32x -48 = 0
The solutions can be found using the quadratic formula:
x = (-32 ±√(32² -4(1)(-48)))/(2(1)) = -16±√304 = -16±4√19
_____
<em>Comment on the equation we used</em>
We notice that when p and q are roots, the equation can be written ...
(x -p)(x -q) = 0 = x² -(p+q)x +pq
You want p+q = -32, pq = -48, so the equation is ...
x² -(-32)x +(-48) = 0
x² +32x -48 = 0 . . . . . . with parentheses eliminated
