Answer:

√100

Step-by-step explanation:

Given the following numbers: √220, -10, √100, 11.5,

Let's arrange the numbers from the largest to the smallest (in descending order).

Note: √220 ≈ 14.8

√100 = 10

From the largest to the smallest number, we have: √220, 11.5, √100, -10

Therefore, the number in the third position is √100

Which equation has the solutions x = 1+
BaLLatris [955]

Answer:

The last equation x2 - 2x -4 = 0

has solution  (x - 1)^2 - 5 = 0,   x  =  1 + root(5)  or  x = 1 - root(5)

Step-by-step explanation:

If a quadratic function has roots 1 and 5

f(x) = (x -1)(x- 5)

f(x) = x^2 - 6x + 5

Unless you meant.  -4 and 6  ?

g(x) = (x + 4)(x - 6)

g(x) = x^2 -2x -24

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

Or did you mean  x = 1 and x =4 ?...

x^2 + 2x + 4 = 0  :   complete square  x^2 + 2x + 1 + 3 = 0,   (x+1)^2 + 3 = 0

x^2 - 2x + 4 = 0 :  complete square:  (x -1)^2 + 3 = 0

0x^2 + 2x - 4 = 0,    2x - 4 = 0,  x = 2

x^2 - 2x - 4 = 0  becomes:   x^2 - 2x + 1 - 1 -4 = 0 ;  (x - 1)^2 - 5 = 0

Need help with this the multiple choice questions aka <>,for each 3 of them are “makes sense, does not makes sense”
polet [3.4K]

When a 4 is rolled on the die, the player is awarded 17 points.

When a 4.5 is rolled on the die, the player is awarded 19 points.

When a 9 is rolled on the die, the player is awarded 37 points.

<h3>Function and values</h3>

Given the function that represents certain number of points is awarded to a player upon rolling a six sided die according to the function.

f(x) = 4x + 1

If the number of die rolled is 4, hence;

f(4) = 4(4) + 1

f(4) = 16 + 1

f(4) = 17

This shows that when a 4 is rolled on the die, the player is awarded 17 points.

If the number of die rolled is 4.5, hence;

f(4.5) = 4(4.5) + 1

f(4.5) = 18 + 1

f(4.5) = 19

This shows that when a 4.5 is rolled on the die, the player is awarded 19 points.

If the number of die rolled is 4, hence;

f(9) = 4(9) + 1

f(9) = 36 + 1

f(9) = 37

This shows that when a 9 is rolled on the die, the player is awarded 37 points.

The volume of a cube decreases at a rate of 0.5ft cubed per minute. What is the rate of change of the side length when the side
DENIUS [597]
The solution to the problem is as follows:

a cube has sides s 

V = s^3 ---> differentiating 

dV/dt = 3s^2 * ds/dt 

0.5 ft^3 / min = 3 * (12ft)^2 * ds/dt 

(1/2) ft^3 / min = 3 * 144 ft^2 * ds/dt 

(144/6) ft^3 / ( ft^2 min ) = ds/dt 

<span>24 ft / min = ds/dt

Determine the equation of the line with slope 3/4 passing through the point 4,0
Vitek1552 [10]

Answer:

y = \frac{3}{4}x - 3

Step-by-step explanation:

If it has a slope of 3/4, then it will look like this:

y = \frac{3}{4}x + b

If it passes through (4, 0), than y = 0 when x = 4

y = \frac{3}{4}(4) + b

y = 3 + b

b = -3

Therefore, the equation is y = \frac{3}{4}x - 3.
