Answer:

<h2>See below</h2>

Step-by-step explanation:

first thing you didn't give any quadratic equation and also didn't allude which method you indeed however I'll give you two methods

  • factoring
  • quadratic formula

to get elaborately factoring method

see this question which is answered by me

  • brainly.com/question/22505331

quadratic formula:

  • \displaystyle \: x =  \frac{ - b \pm \:  \sqrt{ {b}^{2} - 4ac } }{ 2a}

by using this formula we can solve quadratic very early

we just need to substitute the value of a,b and c and simply to get x

Example 1 – Solve: Example 1

Step 1: Identify a, b, and c and plug them into the quadratic formula. In this case a = 1, b = –8, and c = 14.  

Step 1

Step 2: Use the order of operations to simplify the quadratic formula.  

Step 2

Step 3: Simplify the radical, if you can. In this case you can simply the radical into:  

Step 3

Step 4: Reduce the problem, if you can. In this case you can reduce the entire problem by 2.

Suppose the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ =
Natali [406]
Answer: The proportion that will qualify is 0.0314 or 3.14%.

First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.

(128 - 141) / 7 = -1.86

Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.

Find the area of the figure.( sides meet at right angles.)picture below
Tema [17]

You can divide the figure as follows:

  • A vertical rectangle, 5 meters tall and 2 meters wide, on the top right.
  • A horizontal rectangle, 2 meters tall and 5 meters wide, on the bottom left
  • A 2x2 meters square on the bottom right, where the two rectangles meet.

The area of the rectangles is 5x2=10 meters squared, while the area of the square is 2x2=4 meters squared.

So, the total area is 10+4=14 meters squared.

Area of a semicircle is 308cm. Find the perimeter
fgiga [73]

Answer:

72 cm

Step-by-step explanation:

Find the radius using the given information

308=1/2(πr^2)

r^2=616/π

r=14

The perimeter is πr + 2r so plug in 14

π(14) + 2(14)

43.96+28=71.96

Which of the following correctly completes the square for: x^2+2x=48
Ket [755]

Answer:

(x+1)²= 49, the answer is B

Step-by-step explanation:

x² + 2x = 48

x² + 2x + (2/2)² -  (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² -  (2/2)²]

(x+1)²= 49, the answer is B
