Answers

Answer 1

Answer:

   A.  Step I

Step-by-step explanation:

Appropriate application of the distributive property would give ...

  x +2x -10 = 320 . . . . . . . does not match step I

Further solution steps would be ...

  3x -10 = 320

  3x = 330

  x = 110

find the inverse of the function f(x)=4x^3-7​

Answers

Answer:

f^-1(x)=³√[(x+7)÷4]

Step-by-step explanation:

f(x)=4x^3-7

y=4x^3-7

interchange 'y' with 'x'

x=4y^3-7

make y the subject

4y^3=x+7

divide by 4 both sides

y^3=(x+7)÷4

multiply by the cube root both sides

³√(y^3)=³√[(x+7)÷4]

y=³√[(x+7)÷4]

f^-1(x)=³√[(x+7)÷4]

Sanji has a square room with a perimeter of 42.5 feet. If she wants to hang a curtain along one full side of the room, how long does the curtain need to be?

Answers

Answer:

The length of the curtain is 10.625 feet

Step-by-step explanation:

The length of the curtain to cover one side of the room depends on the shape of the room

Given a room shape of a square, we have;

Perimeter = 4 × Side length of the room

Length of the curtain = Side length of the room

Therefore;

Perimeter = 4 × Length of the curtain

42.5 feet = 4 × Length of the curtain

Length of the curtain = (42.5 feet)/4 = 10.625 feet

The length of the curtain = 10.625 feet.

Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time he will use the Same amount of plant food as before how much plant food will he need

Answers

Answer:

3 7/12 kg

He doesn't have enough plant to feed strawberry 2 more times and tomato 1 more time

Step-by-step explanation:

On sunday , sheldon bought 4 1/2 kg of plant food. He uses 1 2/3 kg on his strawberry plants and used 1/4 kg for his tomato plants. b. Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time. He will use the same amounts of plant food as before. How much plant food will be need? Does he have enough left to do so.

Total plant bought = 4 1/2 kg

Strawberry = 1 2/3 kg

Tomato = 1/4 kg

Strawberry + tomato

= 1 2/3 + 1/4

= 5/3 + 1/4

= 20+3/12

= 23/12 kg

Total remaining after Sunday

= Total - used

= 4 1/2 - 23/12

= 9/2 - 23/12

= 54-23/12

= 31/12

= 2 7/12 kg

Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time.

Strawberry = 2 × 1 2/3

= 2 × 5/3

= 10/3 kg

Tomato = 1 × 1/4

= 1/4 kg

Total plant needed to feed strawberry two more times and tomato 1 more time

= 10/3 kg + 1/4 kg

= 40+3/12

= 43/12 kg

= 3 7/12 kg

He will need 3 7/12 kg of plant

He doesn't have enough plant to feed strawberry 2 more times and tomato 1 more time

out of 100 participants in a picnic, 70 drank milk , 40 drank soup and 20 drank both. (i) Represent the above information in a venn diagram. (i) Find the number of participants who drank neither of the drinks.​

Answers

Answer: 10
Explanation:
n(U) = 100
n(M)= 70
n(S)= 20
n(M intersection S)= 20
So,
n(M union S)= n(M) +n(S) - n(M intersection S)
= 70+ 40 - 20
=90
Again,
n( M union S) complement = n(U) - n( M union S)
= 100 - 90
= 10
Therefore, 10 participants drank neither of the drinks.

The cube of a number is less than five times the square of the number. For what set of numbers is this true?
(-0,5)
(5.00)
(-0.0) U (0.5)

Answers

Answer:

[tex](-\infty,0)\cup (0,5)[/tex].

Step-by-step explanation:

Note: In the given options it should be negative infinity instead of -0 because -0 does not make any sense.

It is given that cube of a number is less than five times the square of the number.

Let the unknown number be x.

[tex]x^3<5x^2[/tex]

[tex]x^3-5x^2<0[/tex]

[tex]x^2(x-5)<0[/tex]

This is possible when both factors [tex]x^2\text{ and }(x-5)[/tex] have different sign.

We know that [tex]x^2[/tex] is always greater than or equal to 0. So,

[tex]x-5<0[/tex]

[tex]x<5[/tex]

[tex]x\in (-\infty,0)\cup (0,5)[/tex]

Because [tex]x^2(x-5)<0[/tex] is not true for x=0, so, 0 is not included in the solution set.

Therefore, the solution set is [tex](-\infty,0)\cup (0,5)[/tex].
