An expression is given that has a value between 4.44.4 and 4.54.5, and where xx represents an integer. ​ ​ \sqrt{x}+\sqrt{x} x ​ + x ​ ​ What is the value of xx?

Answers

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

Given

[tex]\sqrt x + \sqrt x = (4.4,4.5)[/tex]

Required

Find x

When the result is 4.4, we have:

[tex]\sqrt x + \sqrt x = 4.4[/tex]

This gives:

[tex]2\sqrt x = 4.4[/tex]

Divide both sides by 2

[tex]\sqrt x = 2.2[/tex]

Square both sides

[tex]x = 2.2^2[/tex]

[tex]x = 4.84[/tex]

When the result is 4.5, we have:

[tex]\sqrt x + \sqrt x = 4.5[/tex]

[tex]2\sqrt x = 4.5\\[/tex]

Divide both sides by 2

[tex]\sqrt x = 2.25[/tex]

Square both sides

[tex]x = 2.25^2[/tex]

[tex]x = 5.0625[/tex]

So, the value of x is between 4.84 and 5.0625

i.e.

[tex]x = (4.84,5.0625)[/tex]

The only integer between the above interval is 5.

Hence:

[tex]x = 5[/tex]

Given f (x) = 5x2 and g(x) = 2x + 3, find f(g(-4))

Answers

Answer:

125

Step-by-step explanation:

Given

f(x) = 5x²

g(x) = 2x + 3

Now

g(-4) = 2 * (- 4) + 3

= - 8 + 3

= - 5

Also

f(g(-4)) = f( -5)

= 5 * ( -5)²

= 5 * 25

= 125

A toy company has 6 different heights of its best-selling action figure, labeled versions 1 through 6. Each version is modeled from clay molding of the action figure. Version 1 is 125% taller than the clay molding of the action figure. The heights of action figure versions 2 through 6 are each 125% taller than the previous version of the action figure. The clay molding of the action figure is 4 inches tall. Which function can be used to find the height in inches of each version of action figure, where 1 ≤ v ≤ 6?
h(v) = 1.25(v+ 4)

h(v) = 4(1.25)v

Hope this helps ;)

Answer:

-24

Step-by-step explanation:

According to the Question ,

⇒ f(x) = -3x + 3 .

For finding the value at x = 9 , put x = 9 ,

⇒ f(9) = -3(9) + 3

⇒ f(9) = -27+3

⇒ f(9) = -24

Hence the value of f(9) is -24 .

A 100
B 110
C 120
D 130
E 140

Answers

Answer:

A (100)

Step-by-step explanation:

If 2 hours pass starting at 23:35 today, then tomorrow the time will be 1:35. The difference between 1:35 and 1:15 is 20 (minutes) Because there are 120 minutes in 2 hours (60 minutes per hour), This means we do 120 minutes minus 20 minutes. This gives us an answer is A, 100 :)
