Identify the quadratic function that contains the points (-1,-4), (0,0) and (2,-10).

f(x) = 3x^2 - x

f(x) = 3x^2+x

f(x) = - 3x^2+x

f(x) =-3x^2-x

Answers

Answer 1

9514 1404 393

Answer:

  (c)  f(x) = -3x^2 +x

Step-by-step explanation:

Points either side of (0, 0) have lower y-values, so you know the parabola opens downward. This eliminates the first two choices.

Trying one of the other points in the one of the remaining equations tells you which equation works.

For example, usint (-1, -4) in the third choice, we get ...

  f(-1) = -3(-1)^2 +(-1) = -3 -1 = -4 . . . . . matches point (-1, -4)

The correct function is the third choice:

  f(x) = -3x^2 +x

Using the distance formula, calculate how far Tre threw the ball. (4 points: 2 points for setup, 1 for calculation, 1 for the answer).

Answers

Answer:

[tex]D = 63.717[/tex]

Step-by-step explanation:

The details that complete the question are:

[tex](x_1,y_1) = (0,42.78)[/tex]

and

[tex](x_2,y_1)=(90,42.78)[/tex]

Required

Determine how far the ball travelled

Distance is calculated using:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute values for x's and y's

[tex]D = \sqrt{(42.78 - 0)^2+(42.78-90)^2}[/tex]

[tex]D = \sqrt{42.78^2+(-47.22)^2[/tex]

[tex]D = \sqrt{1830.1284+2229.7284[/tex]

[tex]D = \sqrt{4059.8568[/tex]

[tex]D = 63.717[/tex]

In a circle with radius 7.8, an angle intercepts an arc of length 44. Find the angle in radians to the nearest 10th.

Answers

Given:

Radius of a circle = 7.8

Intercepted arc length = 44.

To find:

The angle in radians to the nearest 10th.

Solution:

We know that,

[tex]\text{Arc length}=r\theta[/tex]

Where, r is the radius of the circle and θ is the central angle in radians.

Substituting the values, we get

[tex]44=(7.8)\theta[/tex]

[tex]\dfrac{44}{7.8}=\theta[/tex]

[tex]5.641=\theta[/tex]

[tex]\theta\approx 5.6[/tex]

Therefore, the angle in radians to the nearest 10th is 5.6.

x = 8.5

Step-by-step explanation:

You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°

The sum of all angles is 180°

90 + (4x - 8) + (6x + 13) = 180

10x + 95 = 180

      - 95     -95

10x = 85

x = 8.5

Mr. Luu spent 15.99 on new flashlights. If 12 students are using flashlights what is the unit cost per student round the answer to the nearest hundreds.

Answers

Answer:

$1.33 per student

Step-by-step explanation:

Mr. Luu spent 15.99 on new flashlights.

Total number of students = 12

We need to find the unit cost per student. It can be calculated by dividing the total cost and the total number of students.

[tex]C=\dfrac{15.99}{12}\\\\C=1.33[/tex]

So, the required cost per student is 1.33.
