Answer:

B. 126 degrees

Step-by-step explanation:

lets say the angle is x

the equation we have here is the 8th graders divided by the total number of students is equal to x divided by 360 degrees since a circle has a 360 degree angle.

The equation is:

350/1000=x/360

in number form.

350/1000= 0.35 = 35%

so now we know x/360=35%

126/360=35%

so the answer would be 126 degrees.

Transform the given quadratic function into vertex form f(x) = quadratic function into vertex form f(x) = quadratic function int
melisa1 [442]

Answer:

Vertex form: f(x) =(x +\frac{7}{2})^2 -\frac{53}{4}

The vertex is (-\frac{7}{2},-\frac{53}{4})

Step-by-step explanation:

For a general quadratic function the form is:

ax ^ 2 + bx + c

For the function

f(x) = x ^ 2+ 7x -1

The values of the coefficients for the function are the following: a = 1, b =7, c = -1

Take the value of b and divide it by 2. Then, the result obtained squares it.

\frac{b}{2}= \frac{7}{2}

(\frac{b}{2})^2=(\frac{7}{2})^2=\frac{49}{4}

Add and subtract \frac{49}{4}

f(x) = (x ^ 2 +7x +\frac{49}{4}) -\frac{49}{4}- 1

Write the expression of the form

f(x) = (x+\frac{b}{2})^2 +k

f(x) =(x +\frac{7}{2})^2 -\frac{53}{4}

The vertex is (-\frac{7}{2},-\frac{53}{4})

Can someone help me with 1-5 please because i’m really struggling
viva [34]

Answer:

  1. angle SVR = 30°
  2. angle PVR = 90°
  3. angle SVQ = 60°
  4. angle SVP = 120°
  5. angle RVQ = 30°

Step-by-step explanation:

As with finding distances on a number line, the easiest way is to subtract the smaller coordinate from the larger. Here, the "number line" is the arc at the edge of the protractor. The corresponding coordinates are ...

  S: 40°

  R: 70°

  Q: 100°

  P: 160°

The measure of an angle with its vertex at V will be the difference between the "coordinates" of the endpoints of the arc it intercepts. That is ...

  m∠SVR = "R" - "S" = 70° -40° = 30°

The other angles are found the same way:

  m∠PVR = 160° -70° = 90°

  m∠SVQ = 100° -40° = 60°

  m∠SVP = 160° -40° = 120°

  m∠RVQ = 100° -70° = 30°
