Which set of measurements could be the side lengths of a triangle? please help!

1 answer:

3 0

All of them could be as A would be an equilateral B,C,D would be irregular triangles and 3 would be an Isosceles triangle but if you had to go with one it would be A

Answer:

$\large\boxed{f(x)=(1/2)2^x}$

Explanation:

You can just verify the outputs of the four functions for x = -1, x = 0.25, and x = 1.

1. $f(x)=2(1/2)^x$

$x=-1\implies f(x)=2(1/2)^{-1}=2(2)=4$

Then, this function does not go through (-1, 0.25)

2. $f(x)=(1/2)2^x$

$x=-1\implies f(x)=(1/2)(2)^{-1}=(1/2)(1/2)=1/4=0.25\\ \\ x=0\implies f(x)=(1/2)(2)^0=1/2=0.5\\ \\ x=1\implies f(x)=(1/2)(2)^1=(1/2)(2)=1$

Hence, this function goes through the 3 points.

Also, you can verify that it approches y = 0 in quadrant 2, because when x approaches a very large negative number ( - ∞), $2^x$ becomes very small ( approaches zero). Therefore, this function meets all the requirements: it approaches y = 0 in quadrant 2, increases into quadrant 2, and goes through the three given points.

Solve the following for x:

taurus [48]

Step-by-step explanation:

2x(squared)+9x+9=—1

2x(squared)+9x+9+1=0

2x(squared)+9x+10=0

multiply the coefficient of x and 10=2x10=20

2x(squared)+9x+10=0

look for two numbers that when added gives 9and when multiplied gives 20

2x(squared)+5x+4x+10=0

(2x(squared)+5x)+(4x+10)=0

find the number and letters that are common in the equations

x(2x+5)+2(2x+5)=0

(x+2) (2x+5)=0

x+2=0

collect like terms

x=0-2

x=-2

2x+5=0

collect like terms

2x=0-5

2x=-5

divide both sides by 2

2x/2=-5/2

x=-5/2

so x=-2 and -5/2

ΔABC has coordinates A(8, −4), B(2, 2), and C(0, −6). Write the coordinates of the image after a dilation with a scale factor of

MakcuM [25]

Answer:

formula= (kx,ky)

where k = scale factor

= A((8,-4)

= A= (8×12,-4×12)

A= (96,-48)

B= (2,2)

= (2×12,2×12)

B= (24,24)

C= (0,-6)

= (0×12,-6×12)

C= (0,-72)

You have to divide 288 ÷3 that will give you 96 with no remainder. you can check by multiplying 96×3 that will give you 288 . so you have no remainder. no reams were stored
