Evaluate: log(a³b²/c⁴) + log(bc³/a²) - log(a/c) = ?​

Answers

Answer 1

[tex]\large\underline{\sf{Solution-}}[/tex]

We have to evaluate the logarithm.

Given That:

[tex] \rm = \log \bigg( \dfrac{ {a}^{3} {b}^{2} }{ {c}^{4} } \bigg) + \log \bigg( \dfrac{b {c}^{3} }{ {a}^{2} } \bigg) - \log \bigg( \dfrac{a}{c} \bigg)[/tex]

We know that:

[tex] \rm\red\longmapsto \log(x) + \log(y) = \log(xy) [/tex]

[tex] \rm \red\longmapsto \log(x) - \log(y) = \log \bigg( \dfrac{x}{y} \bigg) [/tex]

Therefore, we get:

[tex] \rm = \log \bigg( \dfrac{ {a}^{3} {b}^{2} }{ {c}^{4} } \times \dfrac{b {c}^{3} }{ {a}^{2} } \bigg) - \log \bigg( \dfrac{a}{c} \bigg)[/tex]

[tex] \rm = \log \bigg( \dfrac{ {a}^{3 - 2} {b}^{2 + 1} }{ {c}^{4 - 3} } \bigg) - \log \bigg( \dfrac{a}{c} \bigg)[/tex]

[tex] \rm = \log \bigg( \dfrac{a{b}^{3} }{c} \bigg) - \log \bigg( \dfrac{a}{c} \bigg)[/tex]

[tex] \rm = \log \bigg( \dfrac{a{b}^{3} }{c} \div \dfrac{a}{c} \bigg)[/tex]

[tex] \rm = \log \bigg( \dfrac{a{b}^{3} }{c} \times \dfrac{c}{a} \bigg)[/tex]

[tex] \rm = \log( {b}^{3})[/tex]

As we know that:

[tex]\rm \red\longmapsto \log( {x}^{n}) = n \log(x)[/tex]

Therefore, we get:

[tex] \rm = 3\log(b)[/tex]

MULTIPLY 8 to BOTH SIDES

10x ÷ 8 * 8 = 18 * 8

SIMPLIFY IT

NEW EQUATION: 10x = 144

DIVIDE 10 to BOTH SIDES

10x/10 = 144/10

CANCEL out: 10/10 because it gives you 1

KEEP: 144/10 because it helps simplify for the x-value

x = 144/10

x = 144 ÷ 2/10 ÷ 2

x = 72/5

Therefore, your answer is: x = 72/5

An object is thrown upwards with a speed of 20 m/s. After t seconds, its height can be solved using the formula h = 20t - 4.9t2 where h is the height and t is the time. After how many seconds is the object 19.6 meters high?

Answers

Step-by-step explanation:

h= 20t - 4.9t^2

when h=19.6m

19.6=20t - 4.9t^2

4.9t^2 -20t+19.6=0

solving quadratically

t= 1.64 seconds or t= 2.45 seconds

A package of 6 pairs of insulated gloves costs $38.94. What is the unit price of the pairs of gloves? The unit price is $ per pair of gloves.​

Answers

Answer:

6.49

Step-by-step explanation:

6 pairs of insulated gloves cost $38.94

That means 6 x (price of one glove) = 38.94

Let's say the price of on glove = x

The equation is :

6x = 38.94

x = 38.94 ÷ 6                                   (divide all sides by 6)  

x = 6 + (2.94 ÷ 6)                             (Splitting numbers to multiples of 6)

x = 6 + 0.4 + ( 0.54 ÷ 6)                  (Splitting numbers to multiples of 6)

x = 6 + 0.4 + 0.09                           (Adding all sums)

x = 6.49

Each pair of gloves cost 6.49

find the intersection of the two lines by solving the system of equations please help I will give brainliest

Answers

Answer:

(-3, -5)

Step-by-step explanation:

We can add the two equations together so the x's cancel out:

x + y = -8

-x + y = -2

2y = -10

y = -5

We can substitute y in to get x:

x - 5 = -8

x = -3

This means the intersection is (-3, -5).

For any linear function f(x) = mx + b, when does kf(x) = f(kx)?

Answers

Only when b = 0 or k = 1.

If f(x) = mx + b, then

f (kx) = m (kx) + b = mkx + b

while

k f(x) = k (mx + b) = kmx + kb

The two expression are identical only if

kb = b   ===>   kb - b = 0   ===>   b (k - 1) = 0   ===>   b = 0 or k = 1

How can you tell if an equation (for example, x=16+3y (don’t solve this)) will be represented by a straight line when graphed on a coordinate plane? Is there an easy way to tell or how do you figure that out?

Answers

Answer:

I know it is a straight line because I can convert it into standard or slope intercept form.  An example of when something isn't a straight line is like y=|x|.

x=16+3y

-3y=-x+16

y=1/3x-16/3

An equation where y = whatever and the ALL the variables are to the power of 1, like yours, then the line will be straight.

If the variable looks like x^2 or something, then it will not be a straight line.

(c) If each bag of salt costs $4.85, how much must the aquarium pay for salt to treat all the water in the new dolphin tank?
answer quickly

Answers

The volume of water in the tank is 35,100 cubic feet.

What is the volume of the rectangular prism?

Volume = length × width × height

We have the following parameters based on the information provided;

Length = 20 meters

Width = 13 meters

Height = 5 meters

Substitute the values into the formula to get

Volume = 20 × 13 × 5

Volume = 1300 cubic meters

Convert the cubic yard into cubic feet

1 cubic yard = 27 cubic foot

⇒ 1300 yards = x

⇒ x = 27 × 1300

⇒ x = 35,100 cubic feet

Therefore, the amount of water a bag of salt can treat is 35,100 cubic feet
