The triangles are isosceles and ΔABC : ΔJKL. What is the length of J-L?

Tatiana [17]

You know ABC is isoceles, so AB = BC and BC = 2.5 cm.
That means that the scale factor is KL/BC = 2
So JL = 2AC = 8 cm

Work out (8x10^-3) x (2x10^-4)

love history [14]

Answer:

$1.6 \times 10^{-6}$

Step-by-step explanation:

$(8 \times 10^{-3}) \times (2 \times 10^{-4})$

$8 \times 2 \times 10^{-3} \times 10^{-4}$

$16 \times 10^{-3+(-4)}$

$16 \times 10^{-3-4}$

$16 \times 10^{-7}$

$1.6 \times 10^{-6}$

If y = 6x - 4 which of the following sets represents possible inputs and outputs of the function represented as ordered pairs?

noname [10]

The only of these that is a proper set of ordered pairs for this equations is A) (0,-4) (1,2) (3,14)

In order to prove this, you need to put each ordered pair into the equation and prove that it is a true statement. Below are the examples of this for A.

(0, -4)

y = 6x - 4

-4 = 6(0) - 4

-4 = 0 - 4

-4 = -4 (TRUE)

(1, 2)

y = 6x - 4

2 = 6(1) - 4

2 = 6 - 4

2 = 2 (TRUE)

(3, 14)

y = 6x - 4

14 = 6(3) - 4

14 = 18 - 4

14 = 14 (TRUE)

Therefore, each of these ordered pairs works in the equation.
