Maya should first isolate the variable [tex]\( x^2 \)[/tex] before completing the square.
The steps to solve the quadratic equation [tex]\( 4x^2 + 16x + 3 = 0 \)[/tex] by completing the square are as follows:
1.*Isolate the variable - To do this, Maya should move the constant term to the other side of the equation by subtracting 3 from both sides:
[tex]\[ 4x^2 + 16x = -3 \][/tex]
2. Factor out the coefficient of -The coefficient of x² is 4. Factor out 4 from the terms involving x
[tex]\[ 4(x^2 + 4x) = -3 \][/tex]
3. Complete the square To complete the square, Maya should add the square of half the coefficient of x t both sides of the equation. Half of 4 is 2, and [tex]\( (2)^2 = 4 \),[/tex]so she should add 4 to both sides:
[tex]\[ 4(x + 2)^2 = 1 \][/tex]
After completing these steps, Maya can proceed to solve the equation by isolating x and taking the square root.

A: (3,2)
Since A lies on the mirror line, it will mapped onto itself
A': (3,2)
The required coordinate of image A' is given as (3, 2). Option B is correct.
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
Here,
The Coordinate of A is (3, 2) and the equation of a line is x = 3, since
Point A lies on line x = 3, so the image of the point overlapped the original point. Although the coordinate of the image A' is given as (3, 2)
Thus, the required coordinate of image A' is given as (3, 2). Option B is correct.

Please help!! In radians, what is the period of the function y = .5cos5x
pi/5
(3pi)/2
(2pi)/5
pi/2
Answer:
(2pi)/5
Step-by-step explanation:
The cosine function cos(x) has a period of 2*pi.
If we change the argument of the cosine, the new argument will have a period of 2*pi. If the new argument is 5x, we have that the period will be:
5x = 2*pi
x = 2*pi/5
The period of this function will be (2pi)/5, because for every (2pi)/5 change in the value of x, the function will have the same value. The value of 5 multiplying the cosine does not interfere in the period.

You multiply 47 to 5, because it's 5 tickets and $47 each. You should get $235. Then, you multiply 5 and 5.95. you should get $29.75. Then you add 29.75 to 235. Your final answer is $264.75.
Evaluate the expression when x=-6.
x² + 5x-5
Answer:
1
Step-by-step explanation:
x² + 5x-5
Let x = -6
(-6)^2 + 5(-6) -5
36 -30 -5
6-5
1
To evaluate the expression x² + 5x - 5 for x=-6, substitute -6 into the expression and follow the order of operations to obtain a result of 1.
Substitute -6 for x in the expression, which gives us (-6)² + 5(-6) - 5.Calculate the square of -6, which is 36.Multiply 5 by -6, which is -30.Add these results and subtract 5: 36 - 30 - 5 = 1.Therefore, the value of the expression when x = -6 is 1.
Frank averages a speed of 19 miles per hour during his bike race. The race is 60 miles long.
Answer:
3 hours and 16 minutes or 3.16 for Frank to finish the race
Step-by-step explanation:
60 miles long Frank is going 19 miles an hour
60 divided by 19 3.157 rounded up 3.16
Using the distance and speed, we calculate the time it takes for Frank to complete the bike race. He averages a speed of 19 miles per hour for a 60-mile race, which means it will take him approximately 3.16 hours to finish.
Explanation:This question is about solving a typical problem in math - specifically, calculating time with information on distance and speed. To figure out how long it would take Frank to finish the 60-mile bike race, we use the formula Time = Distance / Speed. Given that Frank averages a speed of 19 miles an hour, we divide the total distance (60 miles) by his average speed (19 mph).
So, 60/19 ≈ 3.16. That means Frank will take approximately 3.16 hour to complete the bike race.

Given points are (5, 20) and (25,5). The distance between the points will be calculated as below:-
D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]
D = √ [ ( 25 - 5 )² + ( 20 - 5)² ]
D = √ ( 400 + 225 )
D = 25 units

First, she needs to find her resting heart rate by counting her pulse for one minute immediately after she wakes up for 5 days in a row. She finds her average resting heart rate to be 62 after
5 days and she remembers the last day's pulse was 58 and all the others were the same. Write and solve an equation to find what her pulse was on all the other days. Justify your answer by showing your steps. Put in Simple equation
Answer:
63
Step-by-step explanation:
She finds her average resting heart rate to be 62 after 5 days.
That means, average of the 5 heart rate pulse=62
If the last day was 58 and all the other days were the same.
Let x be her pulse on the other days,
Then,
[tex]Average, 62=\dfrac{58+4x}{5}\\\text{Cross Multiply}\\58+4x=62 X 5\\\text{Suntract 58 from both sides}\\4x=(62X5)-58\\4x=310-58\\4x=252\\\text{Divide both sides by 4}\\x=63[/tex]
Her pulse on all the other days is 63.

The height of a trapezoid is 6 in. and it’s area is 72 in to the 2nd power. One base of the trapezoid is 6 inches longer than the other base. What are the lengths of the bases? Complete the explanation of how you found your answer.
One base is __ inches for one of the bases and __ inches for the other base.
Use the formula for the area of a trapezoid. Substitute 72 for A and 6 for h and simplify the equation to find __ = (b1 + b2). Use guess and check to find two numbers that add to __ with one number 6 more than the other to get __ inches for one of the bases and __ inches for the other base.
Given:
The height of the given trapezoid = 6 in
The area of the trapezoid = 72 in²
Also given, one base of the trapezoid is 6 inches longer than the other base
To find the lengths of the bases.
Formula
The area of the trapezoid is
[tex]A=\frac{1}{2} (b_{1} +b_{2} )h[/tex]
where, h be the height of the trapezoid
[tex]b_{1}[/tex] be the shorter base
[tex]b_{2}[/tex] be the longer base
As per the given problem,
[tex]b_{2}=b_{1} +6[/tex]
Now,
Putting, A=72, [tex]b_{2}=b_{1}+6[/tex] and h=6 we get,
[tex]\frac{1}{2} (b_{1} +b_{1}+6)(6) = 72[/tex]
or, [tex]b_{1}+b_{1}+6 = \frac{(72)(2)}{6}[/tex]
or, [tex]2b_{1}+6 = 24[/tex]
or, [tex]2b_{1}=24-6[/tex]
or, [tex]b_{1}= \frac{18}{2}[/tex]
or, [tex]b_{1}=9[/tex]
So,
The shorter base is 9 in and the other base is = (6+9) = 15 in
Hence,
One base is 9 inches for one of the bases and 15 inches for the other base.

project requires of a pound. How many projects
can Mrs. Kenny complete without running out of clay?
To find how many projects can be completed, divide the total amount of clay Mrs. Kenny has by the amount of clay required for each project. However, the question seems to be missing the values for the total amount of clay and the amount required per project.
Explanation:Mrs. Kenny is teaching a ceramics class where she uses clay for her projects. As stated, it seems there is a portion of the question omitted which is the number of pounds of clay Mrs. Kenny has and the amount required for each project. Ideally, the number of projects Mrs. Kenny can complete is determined by dividing the total weight of the clay she has by the weight of clay required for each project. For instance, if Mrs. Kenny has 3 pounds of clay and each project requires 1/2 pound of clay, she would be able to complete 6 projects (3 divided by 1/2 = 6).

Nancy's spaghetti and meatballs recipe calls for 2 cloves of garlic the recipe makes 8 servings how much garlic is in each serving
Answer:
1/4 clove
Step-by-step explanation:
Each serving of Nancy's spaghetti and meatballs recipe contains a quarter (or 0.25) of a garlic clove.
Explanation:In the given scenario, Nancy's spaghetti and meatballs recipe asks for 2 cloves of garlic and yields 8 servings. Hence, to find out the amount of garlic in each serving, we need to divide the total cloves of garlic by the number of servings. Hence,
Garlic per serving = Total garlic / Number of servings
Here's how to do the math:
Garlic per serving = 2 cloves / 8 servings = 0.25 cloves per serving
So, there is 0.25 or a quarter of a garlic clove in each serving of Nancy's spaghetti and meatballs recipe.
