Answer:

  • D, A, C, D

Step-by-step explanation:

Q1

  • 6 + ∛3x² = 18
  • ∛3x² = 12
  • 3x² = 12³
  • 3x² = 1728
  • x² = 1728/3
  • x² = 576
  • x = √576
  • x = ±24

Option D

Q2

  • ∛3x² - 5 = 10
  • ∛3x² = 15
  • 3x² = 15³
  • 3x² = 3375
  • x² = 1125
  • x = √1125
  • x = ± 15√5

Option A

Q3

  • 3∛x² - 2 = 7
  • 3∛x² = 9
  • ∛x² = 3
  • x² = 3³
  • x² = 27
  • x = √27
  • x = ±3√3

Option C

Q4

  • ∛4x² + 2 = 9
  • ∛4x² = 7
  • 4x² = 7³
  • 4x² = 243
  • x² = 243/4
  • x = √243/4
  • x = ± 7√7/2

Option D

ABCDE and FGHJE are similar pentagons. If the perimeter of FGHJE is 7.3, what is the perimeter of ABCDE?
monitta
Polygons are said to be equal if the ratio of their corresponding sides and corresponding angles are equal. If the lengths are proportional, then it must be that the perimeter as well are proportional. Therefore, the correct answer is the second option. The perimeter of <span>ABCDE 14.6 units.</span>

Determine if the function f(x)=x+4 is increasing or decreasing on the interval of 2≤x≤5. Justify your answer.
Rudik [331]

Step-by-step explanation:

Given

The function is f(x)=x+4

for x_2>x_1, we will check the values of f(x_1) and f(x_2)

Take 3 and 4

f(4)=4+4\\f(4)=8

Similarly,

f(3)=3+4\\f(3)=7

Thus, f(4)>f(3)

Also, f'(x) is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.
