Answer:

Step-by-step explanation:

(7,-6) (13,2)

2--6. 8. 4

------= ------= ------ (2--6 turns to a +)

13-7. 6. 3

Slope:------

Points=(7,-6)

y--6=----(x-7) (y--6 turns to a +)

4. 28

y+6= ---- x - ----

3. 3

-6. -6

-------------------------

4. 46

y=----- x - -------

3. 3

Whats the percent change of 13.7 to 40.2

k0ka [10]

The percent change of 13.7 to 40.2 is 193.4%

To find percentage change, you need to find the difference between the two numbers. In this case, 26.5.

You then divide 26.5 by 13.7 and move the decimal point two spaces to the right.

Design minimal 2-level AND-OR and NAND-NAND realizations of the following logic function. Draw circuit diagrams of your realizat

Delicious77 [7]

Answer:

Realization :

since there are 3-variable. Therefore 2ⁿ = 2³ = 8

From the attached solution, f(x,y,z) = y' + xz'

also' see the circuit diagrams of my realizations of AND-OR and NAND-NAND

Step-by-step explanation:

See attached picture for minimal 2-level AND-OR and NAND-NAND of the logic function.

f(x,y,z) = y' + xz' was designed from the function f(x,y,z) = Σm(0,1,4,5,6)

Then, minimal 2-level AND-OR was designed and after was NAND-NAND designed as well.

Given the speeds of each runner below, determine who runs the fastest.

Lesechka [4]

Answer:

Debbie runs 9 feet per second: 9 ft/s

Jessica runs 1 mile in 440 seconds: 414/50 ft/s = 207/25 ft/s = 8 7/25 ft/s

jesssica runs 131 feet in 10 seconds: since 1 mile = 5280 ft we have 1/470 mi/s = 5280/470 ft/s = 528/47 ft/s = 11 11/47 ft/s

ron runs 603 feet in 1 minute: 547 ft/min = 603/60 ft/s = 201/20 ft/s = 10 1/20 ft/s

Since:

11 11/47 > 10 1/20 > 9 > 8 7/25

Emily runs the fastest.

A garden in the shape of a right triangle is bordered on one side by a brick wall, on another side by a wooden fence, and on the

MAVERICK [17]

Let
x-----> the measure of the angle formed by the wooden fence and grass

we know that
in a right triangle
tan x=opposite side angle x/adjacent side angle x
opposite side angle x=13 ft
adjacent side angle x=21 ft
so
tan x=13/21x=arc tan (13/21)-----> x=31.76°------> x=32°

the answer is
32 degrees
