Translate to an inequality: *use h to represent the height
Schach [20]
So the height (h) of a cumulus cloud is at least (<u>></u>) 2100 feet (2100 feet)

h<u>></u>2100
at least means the least it can be is 2100 feet, and it can go more

Does anyone know what b is?
sveticcg [70]

Answer: b = 17

Step-by-step explanation: The figure shows a triangle which upon closer observation is actually two triangles placed one inside the other. We have triangle QTR (the larger one) and triangle PTS (the smaller one).

The line PS is parallel to line QR, so in effect what we have here are two similar triangles. The ratios of similarity can be derived as

Line QT/line TR = line PT/line TS OR

Line QT/line QR = line PT/line PS.

With these ratios in mind we can now write the following expressions from the similar triangles;

QT = 2b + (2b - 17) and

TR = 16 + 8

TR = 24

Hence,

2b/16 = 2b + (2b - 17)/24

(That is, PT/TS = QT/TR)

2b/16 = (4b - 17)/24

By cross multiplication we now have,

2b(24) = 16(4b - 17)

By expanding the brackets we now have

48b = 64b - 272

By collecting like terms, 64b now moves to the left side of the equation and becomes negative

48b - 64b = -272

-16b = -272

Divide both sides of the equation by -16

b = 17

**Note** A negative number divided by another negative number yields a positive answer.

Please help ASAP!ill give brainliest !
Vinil7 [7]
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=\frac{7}{9}x^2+3

as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3 

the equation can be written as :\frac{x^2}{25}+ \frac{y^2}{9} =1
