What is a fraction for 0.8

Mathematics
1 answer:
Leni [432]3 years ago
4 0

Answer: 4/5

Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.

Therefore, 0.8 can be written as the fraction 4/5.

What is the image of the point (3,2)(3,2) after a rotation of 90^{\circ}90 ∘ counterclockwise about the origin?
BARSIC [14]

Answer: = (-2,3)

Step-by-step explanation:

  • Rotation is a transformation of a figure by rotating it for a specific angle about a fixed point.

Here, fixed point = origin = (0,0)

Transformation rule for rotation of  90^{\circ}counterclockwise about the origin:

(x,y)\to (-y,x)

Then, the image of the point (3,2) =  (-2,3)

Hence, the image of the point (3,2) after a rotation of  90^{\circ}counterclockwise about the origin = (-2,3)

58. Graph the function y=x^2+3x-18. How many real roots does the function have?
Airida [17]

9514 1404 393

Answer:

  58. 2 real roots; see attached for a graph

  59. -6, 3

Step-by-step explanation:

58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.

__

59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.
