4) The earthquake at New Madrid was of greater intensity than earthquake at San Francisco.

In mathematics, the greater than sign is a basic mathematical notation used to represent an inequality between two values.

The symbol used to denote greater inequality is “>”. It is the commonly accepted mathematical notation of two strokes of equal length that meet at an acute right angle.

A typical use of the greater than sign is to compare two values, where the first  is greater than the second, or one is greater than the other.

The greater than sign is an approximation of a closing square bracket.

Hence, The magnitude of the earthquake was compared to each earthquake's magnitude above.

Using the above exponent rule,  the value of t in the given equality [tex]5^3/ 5^9 = 5^t[/tex] will be t = -6.

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]

WE need to find the value of t in the given equality 5^3/ 5^9 = 5^t

Answer:

Step-by-step explanation:

Let,

One of the siblings age be = x

So, the other siblings ages are = x+2, x+4 and x+6

Since,

Ashley is the oldest sibling so his age is x + 6

∴ By the problem,

=> x + (x+2) + (x+4) + (x+6) = 100

=> 4x + 12 = 100

=> 4x = 100 - 12

=> 4x = 88

=> x = 22

Now,

We got the age of the youngest one that is 22 years

As,

Ashley is the oldest sibling so his age is

= 22 + 6 = 28 years

Hence,

The age of Ashley is 28 years (Ans)

Answer:

28 years old

Step-by-step explanation:

100/4 = 25

The ages are consecutive even numbers,

so add 1 to and subtract 1 from 25.

Add 3 to and subtract 3 from 25.

Ages: 22, 24, 26, 28

Answer:

[tex]y = \dfrac{1}{4} x - 4[/tex]

Step-by-step explanation:

Slope intercept form of line equation is y = mx + b, m = slope, b = y-intercept

Slope of line perpendicular to y =m x + b will have slope   - (1/m)

4x+y=3 can be re-written as
y = -4x + 3

Slope = -4

Slope of line perpendicular to this line is - (1/-4)  = 1/4

Line equation: y = (1/4) x + b

Plug in x, y values from given point into this line equation to find b
-3 = 1/4 x 4 + b

-3 = 1 + b

-3 -1 = b

b = -4

8.5

Step-by-step explanation:

11-3/2-1

11-1.5-1

9.5-1

8.5

For item a, the linear functions are given as follows:

1. y = 1.5x.

2. y = 0.5x - 1.

3. y = -0.5x + 1.

4. y = -1.5x - 1.

For item B, we have that:

1. The functions are:

a. y = 2x + 3.

b. y = 0.5x - 1.

2. The unit rates(slopes) are:

a. 2

b. 0.5.

A linear function is modeled by:

y = mx + b

In which:

In graph 1, the function goes through (0,0), hence b = 0, and through point (2,3), hence the slope is:

m = (3 - 0)/(2 - 0) = 3/2 = 1.5.

Hence the function is:

y = 1.5x.

In graph 2, the function goes through (0,-1), hence b = -1, and through point (2,0), hence the slope is:

m = (0 - (-1))/(2 - 0) = 1/2 = 0.5.

Hence the function is:

y = 0.5x - 1.

In graph 3, the function goes through (0,1), hence b = 1, and through point (2,0), hence the slope is:

m = (0 - 1)/(2 - 0) = -1/2 = -0.5.

Hence the function is:

y = -0.5x + 1.

In graph 4, the function goes through (0,-1), hence b = -1, and through point (2,-4), hence the slope is:

m = (-1 - (-4))/(0 - 2) = -3/2 = -1.5.

Hence the function is:

y = -1.5x - 1.

In table a, the function goes through (0,3), hence b = 3, and through point (1,5), hence the slope is:

m = (5 - 3)/(1 - 0) = 2.

Hence:

y = 2x + 3.

The unit rate, which is the slope, is of 2.

For table b, the function goes through (2,0) and (6,2), hence the slope is:

m = (2 - 0)/(6 - 2) = 1/2 = 0.5.

Hence:

y = 0.5x + b.

When x = 2, y = 0, hence we can find b as follows.

0 = 0.5(2) + b

b = -1.

Thus:

y = 0.5x - 1.

The unit rate is of 0.5.

The amount invested in the growth fund, income fund and money market fund is 20000, 20000 and 10000 respectively

Let the amount invested in the growth fund, income fund and money market fund be x, y and z respectively

As per the question, the company invested twice as much in the income market as in the money market

Therefore,

y = 2z

Equations will be:

x + 2z + z = 50000

12/100x + (8/100)*2z + 5/100z = 4500

Solving the equations

x + 3z = 50000

12x + 21z = 450000

Multiplying the first equation by 7 for equating

7x + 21z = 350000

12x + 21z = 450000

Equating these two we get

5x = 100000

x = 20000

Putting x = 20000 in 7x + 21z = 350000

z = 10000

2z = 20000

So, the amount invested in the growth fund, income fund and money market fund is 20000, 20000 and 10000 respectively

The inverse of the function f (x) = 15 - 3 x is f ⁻¹ (x) = 5 - x/3 which is also a function.

We are given the function:

f (x) = 15 - 3 x

Now, we need to find the inverse of the function.

For this, first we write the function as:

y = 15 - 3 x

Now, we will find the function in terms of x

3 x + y = 15

3 x = 15 - y

x = 5 - y/3

So, the inverse will become:

f ⁻¹ (x) = 5 - x/3

g (x) = 5 - x/3

Now, for one one function:

g (x₁) = g (x₂)

5 - x₁/3 = 5 - x₂/3

- x₁ / 3  = - x₂ / 3

x₁ = x₂

So, it is one - one.

So, the inverse is also a function as every element of x only has one image in y.

Therefore, the inverse of the function f (x) = 15 - 3 x is f ⁻¹ (x) = 5 - x/3 which is also a function.

Answer:

Step-by-step explanation:

Ok, so the question is basically asking where balls height goes up, then down. So the x has to be in the middle of a bounce. That means that x has to be 0, 4, 6, or 8. So the number on the left side must be one of the numbers I just listed. And then the number on the right must be the end of the bounce, so it would be either 4, 6, 8, or 10. So then your answer after looking must be 0<x<4

If the variation is direct, then the value of y decreases with a decrease in x and increases when x increases.

On the other hand side, if we are following inverse variation then the value of y will decrease if x increases and increase if x decreases.

If there is a constant k that is nonzero and such that y = kx, then the variable y fluctuates directly as x. The expression y = kx is referred to as a direct variation equation, and the variable constant is denoted by the number k.

A function with the following equation as its definition is known as an inverse variation: xy = k , where k is a constant real integer that is not zero. There are several instances when one quantity changes as another does so indirectly.

Answer:

Step-by-step explanation:

if you're using Del Math (yk what i'm talking about) it requires you to have a specific way of putting it.

The equation is going to be:

4.25x + 167 = 655.75

your x is going to be:

115

I hope this helps!

For the explanation hopefully, this will make sense (english isn't my first language)

So you know the number of hours: 4.25

cost of the parts: 167

total cost: 655.75

then finally the cost per hour: x

----

so now when you write your equation you're going to end up with the total number of hours (times the cost per hour) added to the cost of the parts, then the remaining will be your total cost. This is how I pictured the equation portion in my head.

for the actual solving part you subtract the cost of the parts from itself as well as the total which should leave you with: 4.25x = 488.75

then you're going to divide 4.25 from each side, as you do.

Then you have the cost of labour per hour: 115

The equation to find the cost of the labor per hour is:

167 + 4.25C = 655.75

The cost of the labor per hour is $115.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Number of hours worked = 4.25

Cost of the parts used = $167

Total cost = $655.75

Now,

We can write an equation to find the C = cost per hour.

167 + 4.25C = 655.75

Solve for C.

167 + 4.25C = 655.75

4.25C = 655.75 - 167

4.25C = 488.75

C = 115

Thus,

The cost of the labor per hour is $115.
