Answer:
truck is 100mph
Step-by-step explanation:
Answer:
V: (4, -2), min, Axis: x = 4, Roots 2 and 6
Step-by-step explanation:
Multiply everything x 2 to get rid of the decimal in front of x^2
2y = x^2 - 8x + 12
Factor
2y = (x - 6)(x - 2)
The roots are at 2 and 6.
The axis of symmetry is in the center between the roots, so it is x = 4.
Put 4 into the original equation to find y
y = 0.5(4*2) - 4(4) + 6
y = 8 - 16 + 6, y = -2
Vertex is at (4, -2). It is a minimum because the graph opens up since x*2 is positive.
You add 5+7 so the total ratio is 12. then divide 48/12=4. you then multiply the given ration 5:7 by 4=20:28. 20 + 28 is 48 students which is given. so there are 28 girls and 20 boys which means there are 8 more girls than boys.
Answer:
The rational numbers are the numbers can be expressed in the form of
<u>Let's see the answer choices:</u>
F The sum of two rational numbers is also a rational number
G 0 is not a rational number.
- This is FALSE as 0 can be expressed in the form of r= p/q, where p = 0
H The product of two rational numbers is also a rational number.
J The opposite of a rational number is also a rational number.
Okay! 4/16= 0.25 because 16/16 = 1 and so that means 12/16 = 0.75 and 8/16 = 0.50 and 4/16 = 0.25 Hope this helped!
