what is the value of log 9 81

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)

Forma ordinaria

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

[tex](x-h)^{2}=4p(y-k)[/tex] (1)  

Donde:

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]

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.

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.

Answer:

112

Step-by-step explanation:

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

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.

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 :)
