The **equation of parabola** in vertex form is y=-3(x+2)^2+6

**What is parabola and equation of parabola in vertex form?**

**Parabola** is equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the **parabola**, and the fixed line is called the **directrix** of the **parabola**.

The **equation of parabola** in vertex form is

y=a(x-h)^2+k

Given the vertex (-2,6) and (-1,3)

h=-2 and k=6

y=a〖(x+2)〗^2+6

To find the value of a at vertex (-1,3)

Put y = 3 and x = -1

3=a(-1+2)^2+6

ABCD is a rectangle that represents a park. The lines show all the paths in the park. The circular path is in the centre of the rectangle and has a diameter of 10 m. Calculate the shortest distance from A to C across the park, using only the lines shown. B 40 m A 70 m C D

Answer is 86.3 m from A to C

This is using 3.14 for pi and rounded to tenths

Step by step

First we will find the diagonal by using Pythagorean theorem a^2 + b^2 = c^2

We know the a & b sides, looking for c the hypotenuse or diagonal

40^2 + 70^2 = c^2

1600 + 4900 = c^2

6500 = c^2

80.6 = c = the full diagonal length.

Now we know the circle has a diameter of 10, so we subtract that from the diagonal length.

80.6 - 10 = 70.6m

Now we need to find the circumference of the circle using C = 2 TT r

We know the diameter is 10, so radius is half of that, so r=5

C = (2) (3.14) (5)

C = 31.4

Since we walk only half of the circle to get from A to C, we divide our circumference by 2.

31.4 / 2 = 15.7

So we have diagonal length of 70.6 + half the circle 15.7 for a total of 86.3m for the path as highlighted on the attachment

Find f(-9) if f(x) = -2x + 5.

Enter DNE if the value does not exist.

f(-9)=

Work Shown:

f(x) = -2x+5

f(-9) = -2(-9)+5

f(-9) = 18+5

f(-9) = **23**

Complete the empty table from the provided information.

Transform the graph of f(x) by dilating it by a factor of -2 and then shift it up 3.

Write the equation of the resulting line in slope intercept form.

The empty table should be completed with the coordinates of the transformed **graph** after a **dilation **with a scale factor of 3 as follows;

x m(x)

4 -2

2 -1

0 0

-2 1

-4 2

The equation of the resulting line in **slope**-intercept form is y = -0.5x + 3.

Based on the given coordinates of the graph of function f(x), the **dilation** with a scale factor of 3 from the origin (0, 0) or center of dilation would be calculated as follows:

Point 1 (-2) → Point 1' (-2 × -2) = Point 1' (4).

Point 2 (-1) → Point 2' (-1 × -2) = Point 2' (2).

Point 3 (0) → Point 3' (0 × -2) = Point 3' (0).

Point 4 (1) → Point 4' (1 × -2) = Point 4' (-2).

Point 5 (2) → Point 5' (2 × -2) = Point 5' (-4).

Next, we would **translate** the **graph** of function f(x) 3 units up as follows:

Point 1 (-2) → Point 1' (-2 + 3) = Point 1' (1).

Point 2 (-1) → Point 2' (-1 + 3) = Point 2' (2).

Point 3 (0) → Point 3' (0 + 3) = Point 3' (3).

Point 4 (1) → Point 4' (1 + 3) = Point 4' (4).

Point 5 (2) → Point 5' (2 + 3) = Point 5' (5).

Now, we can determine the **slope** of the transformed **graph**:

Slope, m = Δy/Δx

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (2 - 1)/(2 - 4)

**Slope**, m = -1/2 or -0.5

Mathematically, the **slope**-intercept form of a straight line is given by;

y = mx + c

Where:

x and y are the points.m represents theAt point (2, 2) and y-intercept c = 3, we have:

y = mx + c

y = -0.5x + 3

Solve for x. Leave your answer in simplest radical form

**Answer:**

x = √213

**I would appreciate this being marked as brainliest... **

**Step-by-step explanation:**

This is a Pythagoras question because we are given two right-angled triangles and no internal angles other than the right angles.

That 7 is annoying because it won't form a Pythagorean triplet with 10. It means that the answer will probably be in radical form.

We can use radicals to represent the common side.

Introduce Pythagoras. The equation below forms a circle on a graph by the way where r is the radius of the circle.

a² + b² = c²;

Substitute the first triangle.

10² + 7² = c²;

100 + 49 = c²;

149 = c²;

c = √149;

Substitute the second triangle.

(√149)² + 8² = x²;

149 + 64 = x²;

213 = x²;

x = √213;

In a case whereby Kaylie is 6 years old and Her sister, Amanda is 2x younger. Kaylie is now 36 the, Amanda age will now be **expressed **as **33 years.**

This implies that when Kaylie is 6 years old then her Her sister, Amanda will be 6/2 = 3 years old.

Then we were told again that ** Kaylie** is now 36, then the age of Amanda will now be (36-3)= 33 years

solve for v: -28 = v +-12

**Answer:**

**v = -16**

**Step-by-step explanation:**

Move the variable to the left-hand side and change its sign, so it would then be **-28 - v = -12**

Then move the constant to the right-hand side and change its sign, so it would become **- v = -12 + 28**

Then you would calculate the sum: **- v = 16**

After doing so, change the sides on both sides of the equation, **v = -16**

**Step-by-step explanation:**

The line has a Y-Intercept of 1, shown as that's where the line passes the Y-Axis. The slope is negative 2, you can find such information by finding one point on a line, then making a triangle to the next point. In this case you would start at (0,1) and go right once (x axis) and down twice (y axis). The slope formula is y2-y1/x2-x1 or change in y/change in x, so if you put 2 (y axis) over 1 (x axis) you would have a slope of 2.

∠1 and ∠2 are vetical angles. If m∠1 =(5x+12)° and m∠2 =(6x−11)°. m∠1=

**⇒Vertical angles are equal .**

**This means that ∠1=∠2**

**⇒The trick is to first find the value of the unknown variable x then substitute it in the expression of ∠1 to get the exact magnitude of the angle.**

[tex]5x+12=6x-11\\5x-6x=-11-12\\-x=-23\\\frac{-x}{-1} =\frac{-23}{-1} \\x=23[/tex]

x=23°

To get the exact value of ∠1 Plug in 23° in the place of x in the expression of ∠1:

[tex]< 1=5x+12\\=5(23)+12\\=127[/tex]

**∠1=127°**

a design engineer wants to construct a sample mean chart for controlling the service life of a halogen headlamp his company produces. he knows from numerous previous samples that when this service life is in control it is normally distributed with a mean of 500 hours and a standard deviation of 20 hours. on three recent production batches, he tested service life on random samples of four headlamps, with these results: sample service life (hours) 1 495 500 505 500 2 525 515 505 515 3 470 480 460 470 what is the mean of the sampling distribution of sample means when the service life is in control? multiple choice 500 hours 515 hours 495 hours 250 hours 470 hours

The **mean** of the sampling distribution of sample means is 495 hours.

**What is the mean of the samples?**

The **mean** of samples is the average of a set of samples or data.

This can be calculated using the formula:

**Mean**= (Sum of terms)/(Number of terms)

Find the **mean** of each sample as shown below:

**Mean** service life of sample 1 = [tex]\frac{495+500+505+500}{4} = \frac{2000}{4}[/tex]

= 500 hours

**Mean** service life of sample 2 =[tex]\frac{525 +515 +505 +515 }{4}=\frac{2060}{4}[/tex]

= 515 hours

**Mean** service life of sample 3 = [tex]\frac{470 +480 +460+ 470}{4}=\frac{1880}{4}[/tex]

= 470 hours

Find the **mean** of the sampling distribution of sample means using the formula:

**Mean** of the sampling distribution (M)

=(Sum of **mean** of given samples )÷( Number of samples)

M = [tex]\frac{500+515+470}{3}=\frac{1485}{3}[/tex]

M=495 hours

So, the **mean** of the sampling distribution of sample means is 495 hours.
