According to the question,
Moving from 0,0 to 4,4
Calculating the slope,
m = 4 - 0 / 4 - 0

Graph this parabola
Show all steps please!!!

Answers

In this case, the equation is in vertex form. To graph the parabola, we need to determine the y-intercept, x-intercept(s), and the vertex.

Vertex of Parabola:

Vertex form: y = a(x + h)² - k

⇒ [y = 3(x + 2 - 1] and [y = a(x - h- k] ⇒ Vertex: (h, k) ⇒ (-2, -1)X-intercept(s) of Parabola:

Assume "y" as 0.

[tex]\implies 0 = 3(x + 2)^{2} - 1[/tex]

[tex]\implies 1 = 3(x + 2)^{2}[/tex]

Take square root both sides and simplify:

[tex]\implies\sqrt{1} = \sqrt{3(x + 2)^{2}}[/tex]

[tex]\implies1 = \sqrt{3 \times (x + 2) \times (x + 2)}[/tex]

[tex]\implies1 = (x + 2) \times \sqrt{3[/tex]

Divide √3 both sides:

[tex]\implies \±\huge\text{(}\dfrac{1 }{\sqrt{3}} \huge\text{)} = (x + 2)[/tex]    

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{1} }{\sqrt{3}} \huge\text{)} = (x + 2)[/tex]    

Multiply √3 to the numerator and the denominator:

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{1} \times \sqrt{3} }{\sqrt{3\times \sqrt{3}}} \huge\text{)} = (x + 2)[/tex]

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{3} }{3}} \huge\text{)} = (x + 2)[/tex]

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{3} }{3}} \huge\text{)} - 2 =x[/tex]

[tex]\implies x = \underline{-2.6...} \ \text{and} \ \underline{-1.4...} \ \ \ \ (\text{Nearest tenth})[/tex]

Y-intercept of Parabola:

Assume "x" as 0.

⇒ y = 3(0 + 2)² - 1⇒ y = 3(2)² - 1⇒ y = 3(4) - 1⇒ y = 12 - 1⇒ y = 11

y-intercept = 11 ⇒ (0, 11)

Determining the direction of the parabola:

Since the first cooeficient is positive (+3), the direction of the parabola will be upwards.

Determining the axis of symmetry line:

Axis of symmetry line: x-coordinate of vertex

Axis of symmetry line: x = -2

Plot the following on the graph:

y-intercept ---> 11 -----> (0, 11)x-intercept(s) -----> -1.4 and -2.6 -------> (-1.4, 0) and (-2.6, 0)Vertex -------> (-2, -1)Axis of symmetry ----> x = -2

Refer to graph attached.

Answer:

Vertex

Vertex form of a quadratic equation:

[tex]y=a(x-h)^2+k\quad \textsf{where }(h,k)\:\textsf{is the vertex}[/tex]

Given equation:  [tex]y=3(x+2)^2-1[/tex]

Therefore, the vertex is (-2, -1)

x-intercepts (zeros)

The x-intercepts are when [tex]y=0[/tex]:

[tex]\implies 3(x+2)^2-1=0[/tex]

[tex]\implies 3(x+2)^2=1[/tex]

[tex]\implies (x+2)^2=\dfrac13[/tex]

[tex]\implies x+2=\pm\sqrt{\dfrac13}[/tex]

[tex]\implies x+2=\pm\dfrac{\sqrt{3}}{3}[/tex]

[tex]\implies x=-2\pm\dfrac{\sqrt{3}}{3}[/tex]

[tex]\implies x=\dfrac{-6\pm\sqrt{3}}{3}[/tex]

Therefore, the x-intercepts are at -2.6 and -1.4 (nearest tenth)

y-intercept

The y-intercept is when [tex]x=0[/tex]:

[tex]\implies 3(0+2)^2-1=11[/tex]

So the y-intercept is at (0, 11)

Plot the graphAs the leading coefficient is positive, the parabola will open upwards.Plot the vertex at (-2, -1)Plot the x-intercepts (-2.6, 0) and (-1.4, 0)Plot the y-intercept (0, 11)

The axis of symmetry is the x-value of the vertex.  Therefore, the parabola is symmetrical about x = -2

**You don't need to plot the axis of symmetry - I have added it so that it is easier to draw the curve**

SolveSo, we know that tantheta is 0.75, or 3 quarters, but we have to find the value of sintheta. If there are 4 angles on a triangle, we can label them as BC and AB.

[tex]because~of~the~angles\\BC = 3k\\AB = 4k[/tex]

Now, we must find the value of AC using the pythagoras theorem.

⇒ (AB)² + (BC)² = (AC)²

in which because of AB and BC's values, goes into...

⇒ (4k)² + (3k)² = (AC)²

because of that ↑ you get the values of what is below.

⇒ (AC)² = 16 k² + 9 k²

add 16k and 9k for the result below.

⇒ (AC)² = 25 k²

⇒ AC = ±5k

Hmm. An angle cannot be negative, so turn 5k to positive 5k. Last but- not least, we have to find the sintheta.

the sin is the side opposite to the angle, so find the hypotenuse and opposite angle.

[tex]Side~opposite~to~angletheta\\= BC(3k)\\\\Hypotenuse\\= AC(5k)[/tex]

That said →  [tex]sintheta = \frac{BC}{AC} = \frac{3k}{5k} = \frac{3}{5}[/tex]

solution:

The distance of the light travels in 100 years is:

5,870,000,000,000 × 100 miles.

To find:

The distance which light can travel in 100 years.

Solution:

to find the distance which light can travel in 100 years, multiply the distance which light can travel in 1 year (5,870,000,000,000 miles) by 100.

[tex] = 5870000000000 \times 100[/tex]

Mr. Richardson is driving to a town 85 miles away. He drives 35 miles per hour for 2 hours before stopping for lunch. He drives 6 more miles and stops for gas. Which expression shows how many miles Mr. Richardson has left to drive?
85 - (35 x 2) - 6
85 - 35 - 2 - 6
(85 - 35) x 2 - 6
85 - 35 + 2 - 6

Answers

Answer:

  (a)  85 - (35 x 2) - 6

Step-by-step explanation:

The miles Mr. Richardson has left to drive will be the difference between the distance to his goal and the miles he has alread driven. The relation between distance, speed, and time can be used to find the miles he drove before lunch.

__

before lunch

  distance = speed × time

  miles before lunch = (35 mi/h) × (2 h) = (35 × 2) mi

total driven

The total miles driven before stopping for gas will be ...

  miles before stopping for gas = (miles before lunch) + (6 more miles)

  = 35 ×2 +6 . . . miles

miles remaining

Then the remaining miles are ...

  remaining = trip miles - miles driven

  = 85 -(35 ×2 +6)

  = 85 - (35 ×2) -6 . . . . . miles left to drive

The mother gave the two sons the same amount of money. When the older son spent $ 275 and the younger $ 250, the younger had 3 times more money than the older. How much money did the mother give to each son? solution: 292​

Answers

Answer:

Each son received from their mother $287.50

Step-by-step explanation:

3(x - 275) = x - 250

2x = 825 - 250

x = 287.50

$287.50 - $275 = $12.50

Check the answer:

After spending the older son has $12.50  

$287.50 - $250 = $37.50

After spending the younger son has $37.50

$37.50 ÷ $12.50 = 3 times

What is geometric sequence?

Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.

It can be given as,

[tex]S=\dfrac{a(1-r^n)}{1-r}[/tex]

Here, [tex]a_1[/tex] is the first term of the sequence, n is the number of terms, and r is the common ratio.

The tallest of a collection of wooden dolls stands 1 meter tall, and each successive doll is half as tall as the one before it.

The second doll is half of the first doll. Thus, the height of the second doll is,

[tex]a_2=\dfrac{1}{2}\\a_2=0.5\rm\;m[/tex]

Similarly, height of third doll,

[tex]a_3=\dfrac{0.5}{2}\\a_3=0.25\rm\;m[/tex]

Here, we see a pattern or sequence in the height of doll,

1,0.5,0.25......

For this series, the value of first term [tex]a_1[/tex] is 1, the number of dolls n is 8 and common ratio r is 0.5. Put the value in the above formula,

[tex]S=\dfrac{1(1-0.5^8)}{1-0.5}\\S=1.992\\S\approx 2\rm\; meters[/tex]

Thus, the combined height of the dolls when the tallest of a collection of wooden dolls stands 1 meter tall, and each successive doll is half as tall as the one before it is 2 meters.
