Answer:
40287600 = B. 4 x 
Step-by-step explanation:
<u>We first have to do the multiplication of the numbers given:</u>
19 * 2,120,400
=> 40287600
<u>Now we have to figure out how many digits are after the number 4:</u>
4, 0 2 8 7 6 0 0
7 digits
Meaning that we need an exponent of 7 for it to be in scientific notation, giving us with the answer B. 4 x 
Answer:
540°
Step-by-step explanation:
90 revolutions = 360°×90 = 32400°
32400° in 60 sec or 1 min
so, in 1 sec 32400/60 = 540°
Answer:
Step-by-step explanation:
Area of a trapezoid is found with the formula, A=(a+b)/2 x h. Learn how to use the formula to find area of trapezoids.
The two parallel sides are the bases, and height, as always, is the perpendicular distance from one base to the opposite. The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the bases of the trapezoid), so its area is half-height × (base1 + base2).
Answer:
2) the quadratic has one x intercept
Step-by-step explanation:
D = 0 => has twin quadratics as one x intercept
Answer:
y + 3 = 1/2(x + 3)
Step-by-step explanation:
Point Slope Form: y - y1(y coordinate) = m(slope)(x - x1(x coordinate))
