What is the multiplicative inverse of
-7
9

Answers

Answer 1
Answer: Since multiplicative inverse is the same thing as reciprocal, the multiplicative inverse is just the denominator and the numerator flipped. So the multiplicative inverse of -7/9 is 9/-7. Hope this helps! If you ever need any more help in math you could always DM me.

If the rate of inflation is 1.9% per yeta, the future price p(t) in dollars of a certain item can be modeled by the following exponential function, where t is the number of years from today P(t)=2000(1.019t$
Find the current price of the item and the price 10 years from today.Round answer in nearest dollars

Answers

Answer:

P(0) = 2000

P(10) = 2414

Step-by-step explanation:

The price for today is given by P(t) when t=0. Put 0 where t is, and do the arithmetic.

P(0) = 2000·1.019^0 = 2000

The price in 10 years is given by P(t) when t=10. Put 10 where t is, and do the arithmetic.

P(10) = 2000·1.019^10 ≈ 2000·1.207096 ≈ 2414

What 1 to the power of 6

Answers

Answer:

1

Step-by-step explanation:

Change the word phrase to a numerical phrase:

1 to the power of 6 = 1^6

1^6 = 1 * 1 * 1 * 1 * 1 * 1

Simplify. Multiply straight across

1 * 1 * 1 * 1 * 1 * 1 = 1

1 is your answer.

~

Hello,

"Power" basically means the amount of times you multiply the base. So, the power of 6 means to apply the base six times (As shown below)

1 * 1 * 1 * 1 * 1 * 1 = 1

The answer would be 1

A. 46 1/2m³

B. 162 3/4m³

C.488 1/4m³

D.528 m³

Answers

The formula for the volume of a rectangular prism is

V=l*w*h   where l=length w=width h=height

Plug in the data we know

V=15 1/2*10 1/2*3
V=488.25 m³
Answer=488.25m³

line m passes through point (-2,-1) and is perpendicular to the graph of y=-2/3x+6. Line n is parallel to line m and passes through the point (4,-3).What is the equation in slope-intercept form of the line n?

Answers

Answer:

Step-by-step explanation:

Line m is perpendicular to . Perpendicular means opposite and reciprocal slope, so

Line n is parallel to Line m. Parallel means same slope, so


Next, input the point (4, -3) and the slope into the Point-Slope formula: y- y₁ = m(x - x₁)


Now, rewrite the equation in Slope-Intercept form - distribute the slope and solve for "y".

   




Answer:

Hello...... here is a solution :

1 -  

Hello:

the   equation of "m" is : y = ax+b

the slope is a : a×(- 2/3) = -1......( perpendicular to a line : y=-2/3x+6 when the slope is -2/3 )

a = 3/2          

the line " n" that passes through (4, - 3) and  parallel to line "m" :  

when the slope is 3/2 ( same slope )

the equation in slope-intercept form of the line" n" is :

 y – (-3)= (3/2)(x – 4)

What is a word problem?

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Let the cost of pencil box be x

Let the cost of notebook be y

Total cost = $6.28

The notebook cost $0.70 more than the pencil box,

Now substitute equation 2 in equation 1,

Hence we can conclude that the cost of notebook is $3.49.

2 lb, 891g, 1 kg, 0.02 T greatest to least

Answers

To arrange in descending order or greatest to least, we will first convert all the values in same unit.

Lets convert all the values in kg

1 lb = 0.45 kg

2 lb = kg

1 g = 0.001 kg

891 g = kg

1 T = 907.185 kg

0.02 T = kg

Hence all values in kg becomes = 0.90 kg , 0.891 kg , 1 kg , 18.14 kg

So in descending order the values become

0.02T, 1 kg, 2 lb, 891 g

Answer:

0.02 T > 1 kg > 2 lb > 891 g.

Step-by-step explanation:

We have given different quantities as: 2 pounds, 891 gram, 1 kilogram, 0.02 Tonnes.

We need to write the given quantities in order from greatest to least.

We know that,

1 pound(lb) = 0.4536 kilogram.

1 gram = 0.001 kilogram.

1 tonne = 1000 kilogram.

We have given different units of different quantities. We can convert the different units of different quantities in a particular unit, say Kilograms(kg). So, we can find the different results by converting the quantities.

2 pounds = 2*0.4536 kilograms = 0.907 kg.

891 gram = 891*0.001 kilograms = 0.891 kg.

0.02 tonne = 0.02*1000 kilograms = 20 kg.

Therefore, the order from greatest to least can be written as: 20 kg > 1 kg  > 0.907 kg > 0.891kg.

Substituting the original units given in problem, the order can be written as:

0.02 T > 1 kg > 2 lb > 891 g.
