Answer:

9/-24 or ~ -0.38

Step-by-step explanation:

x y

3 9

12 -15

from 9 to -15 it will be subtracting 24

From 3 to 12 it will be adding 9

y/x = 9/-24 or -0.375 ~ -0.38

Geometry pls help !!! Find the value of AB. AB = [?]

V125BC [204]

Answer:

AB = 16 Units

Step-by-step explanation:

In the given figure, CD is the diameter and AB is the chord of the circle.

Since, diameter of the circle bisects the chord at right angle.

Therefore, AE = 1/2 AB

Or AB = 2AE...(1)

Let the center of the circle be given by O. Join OA.

OA = OD = 10 (Radii of same circle)

Triangle OAE is right triangle.

Now, by Pythagoras theorem:

$OA^2 = AE^2 + OE^2 \\10^2 = AE^2 + 6^2 \\100= AE^2 + 36\\100-36 = AE^2 \\64= AE^2 \\AE = \sqrt{64}\\AE = 8 \\\because AB = 2AE..[From \: equation\: (1)] \\\therefore AB = 2\times 8\\\huge \purple {\boxed {AB = 16 \: Units}}$

What is the value of the expression f(–3)? -15 3 -3 15

arlik [135]

Answer:

Option A, -15

Step-by-step explanation:

Step 1: Look at the function that needs to be outputted when x = -3

Since x = -3, that means it falls into the first category of x ≤ -3

Step 2: Carry out the instructions

The function for the first category is $-x^{2} + 2x$

$f(-3) =-(-3)^{2}+2(-3)$

$f(-3) = -(9) - 6$

$f(-3) = -15$

Answer: Option A, -15
