A parabola has two x intercepts at (-2 , 0) and (3 , 0) and passes through the point (5 , 10). Find the equation of this parabol

Kamila [148]

Y = a(x + 2)(x - 3) : equation of the parabola in factored form 10 = a(5 + 2)(5 - 2) : (5 , 10) is a point on the graph of the parabola and therefore satisfies the equation of the parabola. a = 5/7: solve the above equation for a.

The local Tupperware dealers earned the following commissions last month. What was the mean commission earned? Round your answe

kirza4 [7]

Answer:

B. $ 3094.01

Step-by-step explanation:

Given observations are,

$2894.21, $1777.15, $2144.77, $4096.37, $4046.29, $1786.37, $3296.69, $4086.27, $2784.22

Number of observations = 10,

Sum of the observations = 2894.21+1777.15+2144.77+4096.37+4046.29+1786.37+3296.69+4086.27+2784.22+4027.79 = 30940.13,

Hence,

$Mean = \frac{\text{Sum of observations}}{\text{Number of observation}}$

$=\frac{30940.13}{10}$

$=3094.013$

$\approx 3094.01$

Option 'B' is correct.

Please help me with a geometry problem, I don't understand.

Goshia [24]

The slope-intercept form:

$y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

m - slope

b - y-intercept

We have the points (1, -5) and (9, 11). Substitute:

$m=\dfrac{11-(-5)}{9-1}=\dfrac{16}{8}=2$

Therefore we have

$y=2x+b$

Put the coordinates of the point (1, -5) to the equation:

$-5=2(1)+b\\\\-5=2+b\qquad\text{subtract 2 from both sides}\\\\-7=b\to b=-7$

<h3>Answer: y = 2x - 7</h3>
