Give The Perimeter Of Each Figure As A Simplified Expression

Answers

Answer 1

Answer:

5k² - 7k + 6

Step-by-step explanation:

The perimeter of the figure given = the sum of all sides of the figure.

Perimeter = (k² - 9k + 23) + (k² + k) + (k² + k) + (2k² - 17)

Simply the expression as follows:

Perimeter = k² - 9k + 23 + k² + k + k² + k + 2k² - 17

Combine like terms

Perimeter = k² + k² + k² + 2k² - 9k + k + k + 23 - 17 (like terms are terms with the same degree)

Perimeter = 5k² - 7k + 6

(07.01) Which of the values for x and y make the equation 2x + 3y + 4 = 15 true? x = 6, y = 3 x = 3, y = 5 x = 6, y = 4 x = 1, y = 3

Answers

Answer:

x = 1, y = 3

Step-by-step explanation:

Given:

2x + 3y + 4 = 15  ⇒ 2x + 3y = 11

Now let's check the pairs of x and y:

x = 6, y = 3

2x + 3y = 2*6 + 3*3 = 12 + 6 = 18 ≠ 11incorrect

x = 3, y = 5

2x + 3y = 2*3 + 3*5 = 6 + 15 = 21 ≠ 11incorrect

x = 6, y = 4

2x + 3y = 2*6 + 3*4 = 12 + 12 = 24  ≠ 11incorrect

x = 1 , y = 3

2x + 3y = 2*1 + 3*3 = 2 + 9 = 11correct

A bee flies at 10 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 12 minutes, and then flies directly back to the hive at 8

feet per second. It is away from the hive for a total of 15 minutes.

a. What equation can you use to find the distance of the flowerbed from the hive?

b. How far is the flowerbed from the hive?

a. Write the equation. Let d be the distance of the flowerbed from the hive.

(Type an equation. Use integers or fractions for any numbers in the equation. Do not simplify.)

Answers

Answer:

a. 15 = d/600 + 12 + d/480

b. 800 feet

Step-by-step explanation:

a. Let distance between hive and flowerbed be "d" feet

Speed of bee during motion from hire to flowerbed = 10ft / sec = (10*60)fit/minute

Speed of bee during reverse motion = 8 ft/sec = (8*60)ft/min

Time which the bee stayed at flower bed = 12 minute

Time of its total journey = 15 minutes

Total Time = Time of travel from hive to flowerbed + Time of staying in flowerbed + Time of reverse travel

15 = d/10*60 + 12 + d/8*60

15 = d/600 + 12 + d/480....................(Required equation)

b. 15 = d/600 + 12 + d/480

d/600 + d/480 = 15 - 12

d/600 + d/480 = 3

4d + 5d  =  3

 2400

9d = 2400 * 3

9d = 7200

d = 7200/9

d = 800 feet

Hence, the flowerbed is 800 feet far from the hive.

Answers

Answer:

step one:

Given the function

y = 14 +2.31x + 4.50

we can solve for the rate of change by applying differentiation.

step two:

differentiating y which is cost with respect to x which is the miles

dy/dx= 0+2.32+0

dy/dx=2.32
