Distance=speed ×time
Answer:
132.5
Step-by-step explanation:
for the triangle 8.5 * 10 / 2 = 42.5
the rectangle 9 * 10 = 90
42.5 + 90 = 132.5
2x² – 5x + 3 = m(x)
Answer:
Step-by-step explanation:
For quadratic ax² +bx +c, the axis of symmetry is x = -b/(2a). For your function, a=2, b=-5, c=3 and the axis of symmetry is ...
x = -(-5)/(2(2)) = 5/4 = 1.25
The vertex is on the axis of symmetry. The y-value there is ...
m(5/4) = (2(5/4) -5)(5/4) +3 = (-5/2)(5/4) +3 = -25/8 +24/8 = -1/8
The vertex is (5/4, -1/8).
The axis of symmetry is x = 5/4.
The leading coefficient is positive, so the parabola opens upward. The vertex is a minimum.
The minimum is -1/8.
The function is defined for all values of x, so ...
the domain is all real numbers.
Values of y can only be -1/8 or greater, so ...
the range is y ≥ -1/8.

9514 1404 393
Answer:
Step-by-step explanation:
The sales tax is ...
7% × $675.50 = 0.07 × $675.50 = $47.285 ≈ $47.29
The total purchase price is ..
$675.50 +47.29 = $722.79
