Can someone help me with this math hw ​

Mathematics
1 answer:
AveGali [126]3 years ago

Answer:

Step-by-step explanation:

F(x) = x² - 2x + 1

      = (x - 1)²

By comparing this equation with the vertex form of the quadratic equation,

y = (x - h)² + k

Here, (h, k) is the vertex

Vertex of the parabola → (1, 0)

x-intercepts → (x - 1)² = 0

                       x = 1

y-intercepts → y = (0 - 1)²

                       y = 1

Now we can draw the graph of the given function,

From this graph,

As x → 0,

\lim_{x \to 0^{-}} (x-1)^2=1

\lim_{x \to 0^{+}} (x-1)^2=1

f(0) = (0 - 1)²

     = 1

Since, \lim_{x \to 0^{-}} (x-1)^2=\lim_{x \to 0^{+}} (x-1)^2=1

Therefore, given function is continuous at x = 0.

Answer:

  B.

  • as x increases, f(x) decreases;
  • as x decreases,f(x) decreases

Step-by-step explanation:

The function is of even degree with a negative leading coefficient. f(x) will tend toward negative infinity as x gets larger or smaller. That is ...

  • as x increases, f(x) decreases;
  • as x decreases,f(x) decreases

_____

<em>Even degree</em> means the end behaviors are the same for both large and small x. <em>Negative leading coefficient</em> means the function value decreases for larger x.

Find the value of x in the triangle shown below 3.5 4 3.5 x• 55•
Dvinal [7]

Answer:

Step-by-step explanation:

Since this is not a right triangle, we will use the Law of Sines. For us that looks like this:

\frac{sin55}{3.5} =\frac{sinx}{4} and cross multiply to get

4sin55 = 3.5sinx and solve for sinx:

sinx=\frac{4sin55}{3.5} so

sinx = .9361737 Use the 2nd button on your calculator and the sin button to find that the angle

x = 69.4°. Not sure how you need it rounded. It's actually 69.4186°

The mean weight of 25 student in a class is 58kg. The mean weight of a class of 29 students is 62kg. Find the mean weight of all
WARRIOR [948]

Answer:

weight of 25 students

25 × 58 = 1450kg

weight of 29 students

29 × 62 = 1798kg

total students = 25 + 29 = 54

total weight of students = 1450 + 1798 = 3248

mean weight of all students = 3248/54 = 60.19kg
