The simplification of the given indices is; D: nine raised to the fourth power divided by three raised to the tenth power

We want to find the expression that is equivalent to the quantity nine raised to the negative second power times three raised to the fifth power end quantity all raised to the negative second power. This is written as;

(9⁻² * 3⁵)⁻²

According to laws of indices, we know that;

(a²)³ = a²*³ = a⁶

Thus;

(9⁻² * 3⁵)⁻² = (9⁻²)⁻² * (3⁵)⁻²

⇒ 9⁴ * 1/3¹⁰

Between which two integers is the value of square root of 11.

Answer:

2

90

Step-by-step explanation:

54 / 3 = 18

so 18 licks per 1 lollipop.

18 + 18 = 36 (aka 2 lollipops).

18 x 5 = 90 (equivalent to 5 lollipops).

Answer:

36/2

90/5

Step-by-step explanation:

54/3=18 36/2=18 and 90/5= 18

According to the solving the LHS = RHS this shows the equality symmetric property.

52 = 52.

LHS is an informal shorthand again for the left-hand side of the an equation in mathematics. Likewise, RHS refers to the right-hand side. Because equality is symmetric, both sides share the same value, expressed differently.

Given the "equality" (=) relation and a = b, if b = a holds true for all a and b, equality is said to be symmetric. For all of a and b, the assertion is TRUE (no counterexample can be found). This is known as the equality symmetric property.

-21-17+25+65=52

Proving that both LHS = RHS :

-21-17+25+65=52

-21-17+25+65=52

- 38 + 90 = 52

52 = 52

So,

LHS = RHS

The distance of Proxima Centauri, which is 4.3 light years away can also be expressed in miles is equivalent to 253.7 x 10¹¹ miles from solar system.

A star is an astronomical object comprising a luminous spheroid of plasma held together by its gravity. The nearest star to Earth is the Sun

Given that a star named Proxima Centauri is 4.3 light-years away. Therefore, we can write that -

Distance [D] = 4.3 light years

The Proxima Centauri is 4.3 light - years away. As given in the question that  light-year is the distance that light travels in one year and 1 light year is equal to 5,900,000,000,000 miles. Therefore in 4.3 light years, there will be -  

D [miles] = 4.3 x 59x 100,000,000,000 = 253.7 x 10¹¹ miles

Using the normal distribution, it is found that:

a) There is a 0.1867 = 18.67% probability that a day requires more water than is stored in city reservoirs.

b) A capacity of 415 million gallons is needed.

c) An amount of 236 million gallons of water use is exceeded with 95% probability.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 310, \sigma = 45[/tex]

For item a, the probability is one subtracted by the p-value of Z when X = 350, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (350 - 310)/45

Z = 0.89

Z = 0.89 has a p-value of 0.8133.

1 - 0.8133 = 0.1867.

There is a 0.1867 = 18.67% probability that a day requires more water than is stored in city reservoirs.

For item b, the capacity should be the 99th percentile, which is X when Z = 2.327, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

2.327 = (X - 310)/45

X - 310 = 45 x 2.327

X = 415. (rounded)

A capacity of 415 million gallons is needed.

For item c, the amount of water use is the 5th percentile, which is X when Z = -1.645, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

-1.645 = (X - 310)/45

X - 310 = -1.645 x 45

X = 236.

Based on the calculations, the value which closest to the mean of the distribution is equal to: B. 18 inches.

A z-value is also referred to as a z-score or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.

In Statistics, z-values can either be positive or negative and it can be calculated by using this formula:

Z = (x - μ)/δ

Where:

If 15 percent of the rainbow trout are longer than 15 inches, then we have:

P(x > 15) = 0.15

From the z-table, the z-value which corresponds to a mean of 0.15 is given by:

z-value = -1.036

Substituting the given parameters into the formula, we have;

Z = (x - μ)/δ

-1.036 = (15 - μ)/2.4

-1.036 × 2.4 = 15 - μ

-2.4864 = 15 - μ

Let the amount needed to be deposited each month be 'x' ;

Monthly interest rate, i = 5%/12 = 0.4167% = 0.004167

Total amount  = $600,000

Total time (in months) = 20 × 12 = 240 years;

Therefore, according to question;

600,000 = x . [(1 + i)ⁿ -1]/i

600,000 = x. [(1 + 0.004167)²⁴⁰ - 1]/0.004167

Let b represent the number of mL of solution B in the mixture. Then (b-400) will be the number of mL of solution A. The number of mL of alcohol in the mix is ...

  0.20(b -400) +0.17b = 179

Step-by-step explanation:

f(1) = -2

The relationship between x and y-values can be represented through a function.

Function Notation

Function notation is one way to write out an equation. In this notation, f(x) represents the y-value at a specified x-value. Thus, f(1) equals the y-value when x is 1. Many times f(x) will be replaced with variable y. So, another way to write the function above is y = -x - 1.

Solving For f(1)

To find f(1), plug 1 into the equation for x.

Now, you can easily solve the equation.

Based on the equation for gravitational force, the value of radius (r) is equal to r = √(GM₁M₂/F).

A gravitational force can be defined as a universal force of attraction which acts between two (2) physical objects, especially by pulling them together.

Mathematically, the gravitational force between two (2) planetary objects is given by this formula:

F = GM₁M₂/r²

Where:

Making r the subject of formula, we have:

Fr² = GM₁M₂

Divide both sides by F, we have:

r² = GM₁M₂/F
