what are the solutions to the quadratic equation (5y 6)2 = 24? y = and y = y = and y = y = and y = y = and y =

Answers

Answer 1

Answer: If you would like to find the solutions to the quadratic equation (5y + 6)^2 = 24, you can do this using the following steps:

(5y + 6)^2 = 24
25y^2 + 2 * 6 * 5y + 36 = 24
25y^2 + 60y + 36 - 24 = 0
25y^2 + 60y + 12 = 0
25 * (y + 6/5)^2 - 24 = 0
1. y = -6/5 - (2 * sqrt(6))/5
2. y = (2 * sqrt(6))/5 - 6/5

The correct result would be y = -6/5 - (2 * sqrt(6))/5 and y = (2 * sqrt(6))/5 - 6/5.

Answer 2

Answer:

The solution to the quadratic equation is y = -2.18 and y = -0.22

How to evaluate the function?

The equation is given as:

(5y + 6)^2 = 24

Expand

25y^2 + 60y + 36 = 24

Subtract 24 from both sides

25y^2 + 60y + 12 = 0

Using a graphical tool, we have the solution to be:

y = -2.18 and y = -0.22

Hence, the solution to the quadratic equation is y = -2.18 and y = -0.22

The toughest part of this problem could be deciding what names to give the quantities of one-Euro and two-Euro coins.

-- I called the number of one-Euro coins ' N '.
Each of them is worth 1 Euro, so all ' N ' of them are worth ' N ' Euros.

-- I called the number of two-Euro coins ' T '.
Each of them is worth 2 Euros, so all ' T ' of them are worth ' 2T ' Euros.

-- The total number of coins in Penny's pocket is (N + T), and it says there are 11.

-- Their total value is (N + 2T), and it says the total value is 18.

So now you have two equations, with two unknowns.

   N + 2T = 18
   N + T = 11

Subtract the bottom equation from the top one, and you get:

(N - N) + (2T - T) = (18 - 11)

   T = 7    (there are 7 two-Euro coins in her pocket)

That right there is the answer to the question, so you don't need to go
any farther. But if you wanted to, you could also figure out how many
one-Euro coins there are in her pocket.

Six blood pressure readings are 115, 120, 123, 121, 121, and 112 mm Hg. What is the average (mean) value?

Answers

Answer:

118.666666667 mmHg

Step-by-step explanation:

To find the average/mean of a set of values, you add all the values together, then divide them by the amount of values in the set.

115+120+123+121+121+112 = 712

Since there is 6 values, you divide this by 6.

712÷6 = 118.666666667 mmHg

Answer:

The standard deviation is 9.34

Step-by-step explanation:

First we need to find mean of the sample:

$m=(23.9+15.3+40.2+30.3+12+22.8)/6=24.08$

Standard deviation will be like below:

$d=√((x-m^2)/6)=9.34$

Answers

If you would like to solve 40% of 32, you can do this using the following steps:

40% of 32 = 40% * 32 = 40/100 * 32 = 0.40 * 32 = 2/5 * 32 = 12.8

The correct result would be 0.4 * 32; 2/5 * 32; 40/100 * 32.

Answer:

$(40)/(100)*32$
