The answer is Letter B - x = 1.5.

First, we'll get the length of the "point" where the circle and the line meets to "S". Since RS = 11, we'll subtract x from 11. So its measurement is 11 - x and that is equal to "S" to the "point". After, we'll get "point" to "T". ST = 14, we'll subtract 11 - x from 14. We can get 4 + x. That measurement is equal to T to "point". The repeat the same process until you reach "point" to R, 3 - x.

To get x, equate both equations. Transpose and simplify.
x = 3 - x
2x = 3
x = 1.5

Note: refer to the attached image for the steps, they're similar except for the given values.

Does the function f(x) = 2x^2− 6x + 9 have a minimum or a maximum? Identify its value.
exis [7]

Answer:

minimum value of function is   \frac{45}{8} .

Step-by-step explanation:

Given function represents a parabola.

Now, here coefficient of x^{2} is positive , so the parabola will be facing upwards and thus the function will be having a minimum.

Now, as we know that minimum value of a parabolic function occurs at

x = \frac{-b}{4a} .

Where , b represents the coefficient of x and a represents the coefficient of x^{2} .

here, a = 2 , b = -6

Thus \frac{-b}{4a} = \frac{6}{8}

                                            =  \frac{3}{4}

So, at x =  \frac{3}{4}  minimum value will occur and which equals

y = 2×\frac{9}{16} - \frac{18}{4} + 9 =  \frac{45}{8} .

Thus , minimum value of function is   \frac{45}{8} .

Can you please help me!!
Molodets [167]
A is more because 1/4 is equal to 2/8 and 2/8 is less than 7/8 so you would have more than a minute
B is three minutes 2/8 goes into 7/8 three times
