6 slices divided by 4 people comes out to 6/4 slices per person, or 3/2, or 1.5 slices per person.

So you are going to do 3 divided by 6

Write the equation of the conic section below.

tangare [24]

Answer:

$(x-3)^2=8(y+1)$

Step-by-step explanation:

Standard form of a parabola with a vertical axis of symmetry:

$(x-h)^2=4p(y-k) \quad \textsf{where}\:p\neq 0$

$\textsf{Vertex}=(h, k)$

$\textsf{Focus}=(h,k+p)$

$\textsf{Directrix}:y=(k-p)$

$\textsf{Axis of symmetry}:h=k$

If p > 0, the parabola opens upwards, and if p < 0, the parabola opens downwards.

From inspection of the graph:

Vertex = (3, -1)
Directrix = y = -3

Therefore:

h = 3
k = -1
k - p = -3

Use the Directrix equation to find p

⇒ y = (k - p)

⇒ -3 = -1 - p

⇒ p = 2

Therefore the equation of the conic section is:

$\implies (x-3)^2=4\cdot 2(y-(-1))$

$\implies (x-3)^2=8(y+1)$

Rearranging in standard form $ax^2+bx+c$ :

$\implies (x-3)^2=8y+8$

$\implies x^2-6x+9-8=8y$

$\implies x^2-6x+1=8y$

$\implies y=\dfrac{1}{8}x^2-\dfrac{3}{4}x+\dfrac{1}{8}$

What is the greatest possible error when measuring to the nearest quarter of an inch

cestrela7 [59]

Using a scale that has increments that are somewhat large, you could get an error if you reach half of the measuring unit. This is because when you arrive at a measurement greater than half of the measuring unit, you would have to round it up. Therefore, the greatest possible error when measuring to the nearest quarter of an inch is 1/8 inch. The greatest possible error when measuring to the nearest quarter of an inch is how the reader reads the measurement. Sometimes, we base our answers to what we can see and what we see may be different from others.

Estimate the area of tje fan if m

kati45 [8]

Answer:

Area of the given fan is 763.4 cm²

Step-by-step explanation:

Area of a sector in a circle = $\frac{\theta}{360}(\pi r^2)$

Here, angle θ = Central angle subtended by the arc

r = Radius of the circle

Since, fan is in the form of a sector of a circle with radius = 27 cm

Measure of the central angle subtended by the arc FN = ∠FAN = 120°

Area of the fan = $\frac{120}{360}(\pi )(27)^2$

= $\frac{729\pi }{3}$

= 243π

= 763.407

≈ 763.4 cm²

Therefore, area of the given fan is 763.4 cm²

What is the area of a sector when theta = 15º and r = 4

Afina-wow [57]

Answer:

2.09 sq. units

Step-by-step explanation:

We can simply use the formula for area of a sector of a circle.

Area of sector = $\frac{\theta}{360}*\pi r^2$

Where $\theta$ is the angle and r is the radius.

<em>It is given that the angle is 15 and radius is 4. We plug them in and find the area:</em>

<em> $\frac{\theta}{360}*\pi r^2\\=\frac{15}{360}*\pi (4)^2\\=\frac{1}{24}*16\pi\\=2.09$ </em>

<em />

<em>Thus area of sector is 2.09 sq. units.</em>
