Encuentra la ecuacion de la parabola con vertice en el origen y foco en las cordenadas 0,1en su forma ordinaria y general

Answers

Answer:

[tex]x^{2}=4y[/tex]

[tex]y=\frac{1}{4}x^{2}[/tex]

Step-by-step explanation:

Forma ordinaria

La ecuación de la parabola de manera ordinaria está dada por:

[tex](x-h)^{2}=4p(y-k)[/tex] (1)  

Donde:

(h,k) es la coordenda del vértice, en nuestro caso (0,0) ya que está en el origen.(h,k+p) es la coordenda del foco, en nuestro caso (0,1).

Por lo tanto h = 0, k = 0 y p = 1.

Remplazando estos valores en la ecuación de la parábola, tenemos:

[tex](x-0)^{2}=4*1(y-0)[/tex]

[tex]x^{2}=4y[/tex] (2)

 

Forma general  

La forma general de una parábola esta dada por la siquiente ecuación

[tex]y=ax^{2}+bx+c[/tex]

Reordenando la ecuación (2) tenemos:

[tex]y=\frac{1}{4}x^{2}[/tex]

Express 25 as power with base 5​

Answers

Answer: express a number in base 5 notation you need to write it in powers of 5. ... 52 = 25 53 = 125 54 = 625. 625 is larger than 613 so I only need a 53 digit, a 52

Step-by-step explanation:

Answer:

POWERS OF 5:

.52 = 25

53 = 125

54 = 625

So 625 is larger than 613

so you will only need 53

but then you also will have 52 so you have 52 as your answer i hope this helps :)

simplyfy: 4x + 8 + x -2 -3x​

Answers

4x+8+x-2-3x
5x +6-3x
2x+6 :D

Answer:

2x+6

Step-by-step explanation:

To simplify an expression such as this you must add like terms. Like terms are terms that have the same variable and power. In this expression 4x, x, -3x are like terms and -2 and 8 are also like terms. To add like terms simply add the coefficients and remember adding a negative is the same as subtracting. So, add the previously listed terms 4x + x + (-3x) = 2x, then -2+8= 6. This means the simplified expression is 2x+6.

Answers

Answer:

Rob.

Step-by-step explanation:

If we take Eric's unit rate and multiply the denominator by two, it will be 14 minutes. Rob's denominator is also 14 minutes. This makes it easier on ourselves. If we multiply the bottom number we also have to multiply the top. So, on Eric's unit rate, we will take the 3 pages and mltiply it by 2 to get 6. 6 is less than 8, so Rob takes the win.

a plane flies 480 miles with a 15 mph tailwind and then back 480 miles with a 15 mph headwind. if the plane completes the trip in 7.2 hours, how fast is the plane traveling against the wind and with the wind

Answers

Since we know the x and y, you would divide 480 by 15 and 32 miles per hour. Then you would multiply 7.2 by 32 and get 230.4. Your trying to find with wind and against wind so just times that by two and get 460.8. I think

find the coordinates of the point which divides the line segment joining the points (4, -3) and (8.5) in the ratio 3:1 internally

Answers

Answer:

The coordinates of the division point are (7, 3)

Step-by-step explanation:

The coordinates of the point (x, y) which divides a segment with endpoints (x1, y1) and (x2, y2) at a ratio m1: m2 internally is ([tex]\frac{m1x2+m2x1}{m1+m2}[/tex] , [tex]\frac{m1y2+m2y1}{m1+m2}[/tex] ).

∵ The line segment joining the points (4, -3) and (8, 5)

x1 = 4 and x2 = 8

y1 = -3 and y2 = 5

∵ The point divides the segment at ratio 3: 1

m1 = 3 and m2 = 1

→ By using the rule above

∵ x = [tex]\frac{(3)(8)+(1)(4)}{3+1}[/tex] = [tex]\frac{24+4}{4}[/tex] = [tex]\frac{28}{4}[/tex]

x = 7

∵ y = [tex]\frac{(3)(5)+(1)(-3)}{3+1}[/tex] = [tex]\frac{15-3}{4}[/tex] = [tex]\frac{12}{4}[/tex]

y = 3

The coordinates of the division point are (7, 3)

There are 12 tomato plants in a garden. Each plant has 7 branches ad each branch has 4 tomatoes growing on it. If one-third of the tomatoes are picked, how many tomatoes were picked

Answers

Answer:

112

Step-by-step explanation:

4*7=2828*12=336336*(1/3)=112

If one-third of the tomatoes are picked, the number of tomatoes that were picked is 112 tomatoes.

Number of picked tomatoes:

Number of picked tomatoes=(Growing tomatoes× Tomatoes branch× Tomatoes plant)× One-third

Number of picked tomatoes=(4×7×12)×1/3

Number of picked tomatoes=336×1/3

Number of picked tomatoes=112 tomatoes

Inconclusion if one-third of the tomatoes are picked, the number of tomatoes that were picked is 112 tomatoes.

What is the value of the expression when a = –5 and c = –1? The expression is 8(a + 2c)

Answers

Answer:

8(a + 2c) = -56

Step-by-step explanation:

Given that,

An expression : 8(a + 2c)

We need to find the value of the above expression when a = -5 and c = -1.

Put the values of a and c in the given expression.

8(a + 2c) = 8(-5+2(-1))

= 8(-5-2)

= 8(-7)

= -56

Hence, the value of the given expression is -56.
