Answer:
8.484
Step-by-step explanation:
Answer:
b=15
Step-by-step explanation:
8²+b²=17²
b²=225
b=15
A system of linear equations can have no solution if the lines are parallel to each other. Looking at the given equation, it has a slope of 8. Any different equation having the same slope will belong to the system of equation without solution. So, the family of equations is:
y = 8x + k
where k is any real number but not equal to 7
Answer:12
Step-by-step explanation:
The area of the triangle in quadrant 2 is 8.
The area of the rectangle in quadrant one is 2.
The triangle in quadrant 1 is 2.
2+2+8=12.
Answer:
y = 2·5^x
Step-by-step explanation:
Using the given points, we can solve for 'a' and 'b'.
y = ab^x
2 = ab^0 = a . . . . . substitute (0, 2) for (x, y)
__
1250 = 2·b^4 . . . . substitute for 'a' and (4, 1250) for (x, y)
625 = b^4 . . . . divide by 2
5 = b . . . . . . . take the 4th root
The function is ...
y = 2·5^x
____
<em>Additional comment</em>
There are two real and two imaginary 4th roots of 625. Only the positive real root is useful as the base in an exponential function like this.
