Answer: Distance of earth from star = [tex]24.78\times10^{14}\text{ miles}[/tex]

Step-by-step explanation:

Given: A certain star is [tex]4.2 \times 10^2[/tex] light years from the Earth.

One light year is about [tex]5.9 \times 10^{12}[/tex] miles.

Distance of earth from star = [tex]4.2\times10^2\times 5.9\times10^{12}[/tex]

[tex]=4.2\times5.9\times10^2\times10^{12}\text{ miles}\\\\=24.78\times10^{2+12}\text{ miles}\\\\=24.78\times10^{14}\text{ miles}[/tex]

Hence, Distance of earth from star = [tex]24.78\times10^{14}\text{ miles}[/tex]

Answer:

y+2=-4(x+9)

Step-by-step explanation:

Point slop form: y-y₁=m(x-x₁)

X-coordinate is -9 and the y-coordinate is -2.

slope is -4.

y-(-2)=-4(x-(-9))

y+2=-4(x+9)

Answer: 6 months i just did this

Step-by-step explanation:

The volleyball team is selling 700 snack bags to raise money.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Sales of pretzels and cheese puffs represent 30% of overall sales, which means that 210 bags were sold.

This ratio could be established,

⇒ 210/30% = x/100%

⇒ x = (210)100%/30%

⇒ x = 70×10

⇒ x = 700

Thus we could evaluate that there are 700 bags in total.

Therefore, the volleyball team is selling 700 snack bags to raise money.

The parts of algebraic expression are monimal, polynimial, binomial, trinomial, and multinomial. An algebraic expression represents all the possible values of variable it consist.

Algebraic Expression- Algebraic expression is the combination of variables, coefficient, constant or all three in a mathematical form  where both side set equal to each other.

Parts of algebraic expression-

The way algebraic expression can express are categorizes in 5 different parts. These are,

        For example  [tex]ax^2[/tex]

         For example  [tex]2b+5c[/tex]

        For example   [tex]5X^2-10y^2[/tex]

        For example   [tex]ax^2+by^3-xy^2[/tex]

        For example [tex]a^2+b+c^3+d[/tex]

An algebraic expression represents all the possible values of variable it consist. We use algebraic equation when we do not know the value of variable or unknown things. To find out the values of these variables the algebraic expression are useful.

Hence the parts of algebraic expression are monimal, polynimial, binomial, trinomial, and multinomial. An algebraic expression represents all the possible values of variable it consist.

Answer: D) Flat area with a large number of plants

The roots of the plants hold in the soil, which prevents/reduces erosion.

The steeper slope means gravity pulls down the soil material faster, since there is less ground in the way to hold it up, so to speak. So flatter areas are less prone to erosion compared to steeper areas.

So that's why overall, flatter areas with lots of plants would have the least erosion.

Step-by-step explanation:

We are given:

Horizontal distance of the point of observation from the building = 2 miles

Angle of elevation of the building = 5 degrees

Finding the height of the Building:

Let the height of the building be x miles

In the given case, the following right-angled triangle will be formed

We know that:  Tan(θ) = Opposite / Adjacent

So, Tan(5°) = x / 2

0.0875 = x/2                                   [since Tan(5°) = 0.0875 ]

x = 0.175                                         [Multiplying both sides by 2]

Height in Meters:

We know that 1 mile = 1609.344 meters

So, we can say that:

1609.344 meters / 1 mile  =  1

Multiplying the height of the building by 1

0.175 miles * 1

since 1 = 1609.344 meters / 1 mile:

0.175*1609.344 meters

[tex]0.175 miles * \frac{1609.344 meters}{1 mile}[/tex]

Here, the 'miles' in the numerator and the denominator will cancel out

281.6 meters

Hence, the height of the Building is 281.6 m OR 0.175 miles

The Answer would be 2/25 or 0.08

Step-by-step explanation:

Turn -0.005 into -5/100. Then multiply it by the reciprocal of -5/8 which is -8/5. We can simplify and it will get us to -1/25 * -2. We know that if we multiply 2 negatives together, it will equal to a positive. And so, we get our answer which is 2/25 or 0.08

Answer:

there were 14 large boxes purchased

Answer: B (-2)

Step-by-step explanation:

[log base b of a = c] turns into [b^c = a]

You have log base 5 of 1/25 = ?, so it turns into 5^? = 1/25

This part is sort of guess and check, but we can look at it to find the answer pretty easily. First, it's 1/n, so we should use a negative power: 5^-1 = 1/5

In addition to being in the denominator, it's 25, which is 5^2.

So, if we want to put it in a reciprocal as well as square it, we can use -2:

5^(-2) = 1/(5^2) = 1/25

Since -2 (B) is the exponent we place on 5 to get 1/25, it is also the answer to log base 5 of 1/25.

The value of log5 (1/25) is -2.

To evaluate the expression log5 (1/25), we need to determine the exponent to which we must raise 5 to get 1/25.

In other words, we need to find the value of x in the equation 5ˣ = 1/25.

We can rewrite 1/25 as 5⁻², since 5⁻² is equal to 1 divided by 5².

Now, we have the equation 5ˣ = 5⁻².

To find the value of x, we can equate the exponents:

x = -2.

Therefore, the value of log5 (1/25) is -2.

Option B) -2 is the correct answer.

The logarithm base 5 of 1/25 is -2 because -2 is the exponent to which we must raise 5 to obtain 1/25. In general, the logarithm function provides the exponent needed to produce a specific value as the result of raising the base to that exponent.

#SPJ6

Answer:

by definition, an exponential function with base c is defined by h (x) = ac^x  

where a ≠0, c > 0 , b ≠1, and x is any real number.

The base, c, is a constant and the exponent, x, is a variable.  

so if we have  f(x)=3(3\8)^2x, this equivalent to f(x)=3(3\8)^y(x),  

where y (x)=2x,  

therefore, the base is  3/8, and the variable is the function y (x)=2x,  it is 4
