The narrowest parabola will be the one with the greatest magnitude of acceleration...y, dy/dx, d2y/dx2 for each are:

-2x^2, -4x, -4

-x^2, -2x, -2

x^2, 2x, 2  and your fourth equation is the same as the third?

From what you have the first equation, -2x^2, will be the narrowest because it has the greatest magnitude of acceleration |-4|=4

GIven data

Width= 44in

Length= 24in

Diagonal=???

We know that the expression for the diagonal is given as

D^2= W^2+L^2

substitute

D^2= 44^2+24^2

D^2= 1936+576

D^2= 2512

D=√2512

D= 50.11

Hence the size of the TV is 50 inches Approx

ANSWER TO BE NAMED BRAINLIEST GET 20 PTS , GET A THANK YOU, A FRIEND REQUEST, AND A 5 STAR VOTE FOR YOU ANSWER PLEZ ANSWER ONLY
Alexxx [7]

Answer:

A. 25 girls

Step-by-step explanation:

Suppose the number of boys is b and the number of girls is g.

We know that the ratio of boys to girls is 6 to 5, so we can write this as:

b:g = 6:5   or    b/g = 6/5

We also know that there are 30 boys, so b = 30. We plug this value of 30 in for b in our ratio. Now, we just have a proportion with one variable g:

\frac{b}{g} =\frac{6}{5}  ⇒  \frac{30}{g} =\frac{6}{5}

Cross-multiplying, we get:

6 * g = 30 * 5 = 150

g = 150/6 = 25

Thus, there are 25 girls, so the answer is A.

Hope this helps!
