9. Her ratio is totally upside down. It’s supposed to be 1/12. It’ll be 276/12, and that’ll give you how many teachers there are. 276/12 is 23. That means that there are 23 teachers.
10. I’d say never or sometimes. Ratios can literally be any numbers. Anything. In any order.

What is the equation of the perpendicular bisector of the segment joining points A(1, 1) and B(5, 7)?
Elden [556K]
Bisector must pass through the mid-point, so we have to find out that mid-point of the segment:

mid point = x₁+x₂ / 2 , y₁+y₂/2
= 1 + 5 / 2 , 1 + 7 / 2
= 6/2 , 8/2
= (3, 4)

Slope of given segment = m = y₂-y₁ / x₂- x₁
m = 7-1 / 5-1
m = 6/4
m = 3/2

Now, segment which is perpendicular, will have the opposite & reciprocal slope, So, it would be: -2/3

We know, y - y₁ = m(x - x₁)
y - 4 = -2/3(x - 3)
y - 4 = -2/3x + 2
y = -2/3x + 6

In short, Your Final Answer would be: y = -2/3x + 6

Hope this helps!

The height of a baseball after it is struck by a bat is modeled by the function h(x) = 3 + 128x − 16x2, where x is the elapsed t
evablogger [386]

Step-by-step explanation:

The constant 3 is the y-intercept of h(x).  Physically, it is the initial height of the baseball.

Help me with this assignment please I don’t understand it
aivan3 [116]
The relationship is a function. A function is an equation of graph that has no repeated x values. In this graph, each x value has a different y value, whether it's (1, 70) or (9,95)

If Rachel gets anything other than a 95, the x value of 2 will have more than one y value: 95 and whatever grade Rachel gets. Therefore it will no longer be a function.
