I’m starting to learn this in class, starting today. it may be wrong.
but to complete a quadratic square, you do (b/2)^2
which b would be 8.
so (8/2)^2
which would turn out to be 16

so the number added to complete the square would be 16.

Answers

Answer:

area = 153.94

Step-by-step explanation:

Diameter = 14. Half of 14 is 7, so radius = 7.

Formula for the area of a circle = π * r^2, so π * 7^2 = 153.93804

Answer:

The equation of the axis of symmetry is x = 7

Step-by-step explanation:

Mathematically, we have the equation of the axis of symmetry as;

x = -b/2a

where a is the coefficient of x^2 = 1

b is the coefficient of x which is -14

So, the equation of the axis of symmetry will be;

x = -(-14)/2(1) = 14/2 = 7

So the equation of the axis of symmetry is x =7

Use both the first and second derivative tests to show that f(x) = 3x2 − 6x + 1 has a relative minimum at x=1.

Answers

Step-by-step explanation:

Given: f(x) = 3x^2 − 6x + 1. x ∈ (-∞, ∞)

now differentiating f(x) w.r.t. x we get

f'(x) = 6x-6

equating it 0 we get

x = 1, which is a critical point

Now using second derivative test to check relative maxima or minima

f''(x) = 6 >0

⇒ x=1 is a relative minima.

also, x=1 f(1) = 3-6+1 = -2

please help me solve for x and find missing side lengths and angle measures,,

Answers

Answer: 90

Step-by-step explanatio

Answer:

the angle measure for angles T and V would be 127 because they are on opposite locations from each other. the angles S and U would 53 because T and U are coplemantery angles (180 degrees) so you subtract. 180-127 to get 53. To find x, on angle S, we simply subtract 1 from 53 (53-1) and divide the answer by 2. To find the lengths of the sides, put them next to each other and separet

them by an equal sign. subtract 3y from both sides of the equation and add 5 to both sides of the equation to get 3y=12. then divide 12 by 3 to get 4 so y=4. Then, simply replace the y with a 4 and solve the equations of the sides.

Alex records the running time—the number of minutes a movie lasts from start to finish—of 50 popular movies. The distribution of times, in minutes, is displayed in the histogram below.

Answers

Answer:

You forgot to attach the question and the histogram.

Is your question “the interval containing the most movies” ? If yes, then the answer is :

Interval 90-100 minutes

Step-by-step explanation:

A histogram is a chart that is used to represent data in form of bars.

Like every other chart, it consists of both the x and y axis. The y axis contains the frequency or percentage of occurrences while the x axis contains the range or intervals.

To determine the interval with the most occurrences, that is the interval containing most movies, we look for the bar with the most height. The bar that is tallest amongst others has the most movies in its running time.

From the attached histogram, the interval containing the most movies is the 90- 100 minutes interval.

This simply means that from Alex’s record, out of the 50 popular movies, more movies run with the 90-100 minutes interval.

PS: view the attached histogram
