Answer:

1)  \(\mathbf{5^{-3}=\frac{1}{125}}\)

2)  \(\mathbf{-5^{-3}=-\frac{1}{125}}\)

3)  \(\mathbf{(-5^{-3})^{-1}=-125}\)

4)  \(\mathbf{(-5^{-3})^0=1}\)

Step-by-step explanation:

We need to solve the exponents

1) \(5^{-3}\)

We know that: \(a^{-1}=\frac{1}{a}\)

\(5^{-3}\\=\frac{1}{5^3}\\=\frac{1}{125}\)

So, we get \(\mathbf{5^{-3}=\frac{1}{125}}\)

2) \(-5^{-3}\)

We know that: \(a^{-1}=\frac{1}{a}\)

\(-5^{-3}\\=-\frac{1}{5^3}\\=-\frac{1}{125}\)

So, we get \(\mathbf{-5^{-3}=-\frac{1}{125}}\)

3) \((-5^{-3})^{-1}\)

We know that: \((a^m)^n=a^{m*n}\)

Using this rule:

\((-5^{-3})^{-1}\\=-5^{-3*-1}\\=-5^{3}\\=-125\)

So, we get \(\mathbf{(-5^{-3})^{-1}=-125}\)

4)  \((-5^{-3})^0\)

We know that: \((a^m)^n=a^{m*n}\)

Using this rule:

\((-5^{-3})^0\\=-5^{-3*0}\\=-5^{0}\\We\:know\:a^0=1\\=1\)

So, we get \(\mathbf{(-5^{-3})^0=1}\)

Answer:

The integers are -58, -57, -56.

Step-by-step explanation:

The difference between two consecutive integers is 1.

If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.

Integers: x, x + 1, x + 2

The sum of the first and third is: x + x + 2

3 times the sum of the first and third is: 3(x + x + 2)

That product equals -342.

3(x + x + 2) = -342

3(2x + 2) = -342

Divide both sides by 3.

2x + 2 = -114

Subtract 2 from both sides.

2x = -116

Divide both sides by 2.

x = -58

x + 1 = -57

x + 2 = -56

The integers are -58, -57, -56.

The two numbers are 7/6 and 5 when the sum of two numbers is 3 more than four times the first number.

Let's call the two numbers x and y, where x is the first number and y is the second number.

The problem gives us two equations that relate the two numbers:

\(x + y = 3 + 4x\\y - x = 2y - 10\)

We can substitute the expression for y from equation 1 into equation 2:

\(y - x = 2(3 + 4x) - 10\)

Expanding the right side and simplifying, we get:

\(y - x = 6 + 8x - 10\\y - x = 8x - 4\)

Adding x to both sides:

\(y = 9x - 4\)

Substituting this expression for y into equation 1:

\(x + (9x - 4) = 3 + 4x\)

Expanding and simplifying the right side:

\(10x - 4 = 3 + 4x\)

Subtracting 4x from both sides:

\(6x - 4 = 3\)

Adding 4 to both sides:

\(6x = 7\)

Dividing both sides by 6:

\(x = 7/6\)

Substituting this value of x back into the expression for y:

\(y = 9x - 4 = 9 * (7/6) - 4 = 63/6 - 4 = 9 - 4 = 5\)

So the two numbers are 7/6 and 5.

For the first question, we are given two functions, f(x) and g(x), and we are asked to find f(g(0)). First, we need to find the value of g(0):

g(x) = -6x² - 2x + 6
g(0) = -6(0)² - 2(0) + 6
g(0) = 6

Now, we need to find f(g(0)):

f(x) = x - 2
f(6) = 6 - 2
f(6) = 4

So, the answer to the first question is 4.

For the second question, we are given the function h(x) and asked to decompose it into component functions f(x) and g(x) so that h(x) = f(g(x)). The function h(x) is:

h(x) = (3x - 5)²

Comparing this with the given options, the correct decomposition is:

h(x) = f(g(x)), where f(x) = x² and g(x) = 3x - 5

This is because when we apply f(g(x)), we get:

f(g(x)) = f(3x - 5) = (3x - 5)²= h(x)

The snail will take approximately 0.43 hours or 25.8 minutes to travel 12 feet at the speed of 8.5 meters per hour.

Given, A snail moves at a speed of 8.5 meters per hour, 1m = 3.28ft. Let's convert meters per hour into feet per hour by multiplying it with 3.28ft/m. So, 8.5 meters per hour = 8.5 × 3.28 feet per hour ≈ 27.88 feet per hour.

Now, to calculate the time taken by a snail to travel 12 feet, we can use the formula: Time = Distance ÷ Speed

Time taken = 12 feet ÷ 27.88 feet per hour ≈ 0.43 hours (rounded to two decimal places)

Now, let's convert 0.43 hours to minutes by multiplying it with 60 minutes per hour: 0.43 hours × 60 minutes per hour ≈ 25.8 minutes (rounded to one decimal place). Therefore, it will take approximately 0.43 hours or 25.8 minutes for the snail to travel 12 feet at the speed of 8.5 meters per hour.

The rate of change of temperature in the direction from (1, 1) to (2, -4) is given by the expression obtained in step 4 after simplification.

To find the rate of change of temperature in the direction from (1, 1) to (2, -4), we need to calculate the directional derivative of the temperature function T(x, y) = x^2e^(-2x^2-3y^2) in the direction of the line connecting these two points. Let's go through the steps:

Find the unit vector in the direction of the line from (1, 1) to (2, -4):

The direction vector can be calculated by subtracting the coordinates of the starting point from the coordinates of the endpoint:

Direction vector = (2 - 1, -4 - 1) = (1, -5)

To obtain the unit vector, we divide the direction vector by its magnitude:

||(1, -5)|| = √(1^2 + (-5)^2) = √26

Unit vector = (1/√26, -5/√26)

Calculate the gradient of the temperature function:

The gradient of T(x, y) is given by:

∇T(x, y) = (∂T/∂x, ∂T/∂y)

Taking partial derivatives, we have:

∂T/∂x = 2xe^(-2x^2-3y^2) - 4x^3e^(-2x^2-3y^2)

∂T/∂y = -6yxe^(-2x^2-3y^2)

Evaluate the gradient at the starting point (1, 1):

∇T(1, 1) = (2e^(-5) - 4e^(-5), -6e^(-5))

Compute the dot product of the gradient and the unit vector:

Rate of change = ∇T(1, 1) · Unit vector

= (2e^(-5) - 4e^(-5))(1/√26) + (-6e^(-5))(-5/√26)

Simplifying the expression and combining like terms, we obtain the rate of change of temperature in the specified direction.

To find the rate of change of temperature in a specific direction, we need to calculate the directional derivative of the temperature function. In this case, we found the unit vector representing the direction from (1, 1) to (2, -4) and computed the gradient of the temperature function at the starting point.

By taking the dot product of the gradient and the unit vector, we obtained the rate of change of temperature in the specified direction. The dot product measures the component of the gradient in the direction of the unit vector, indicating the rate at which the temperature changes as the bug moves along the given path.

The final expression, after simplification, provides the exact value of the rate of change of temperature in the desired direction, incorporating the specific values and the exponential terms in the temperature function.

The time taken by the rocket will be equal to 7 seconds.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The given function is:-

h(x)  =  -5x²  +  25x  +  70

Now to find the time put h(x) equal to zero.

-5x²  +  25x  +  70 = 0

x²    -   5x    -   14   =  0

x²    -   7x  +   2x   -14    =  0

x (  x  -   7)  +  2  (  x  -  7  )  =  0

The angle between vectors u and v is approximately 43.7 degrees to the nearest tenth of a degree.

To find the angle between two vectors, we can use the dot product formula and the magnitude of the vectors. The dot product of two vectors u and v is given by:

u · v = |u| |v| cos(theta)

where |u| and |v| are the magnitudes of vectors u and v, respectively, and theta is the angle between the vectors.

Given vectors u = <6, 4> and v = <7, 5>, we can calculate their magnitudes as follows:

|u| = sqrt(6^2 + 4^2) = sqrt(36 + 16) = sqrt(52) ≈ 7.21

|v| = sqrt(7^2 + 5^2) = sqrt(49 + 25) = sqrt(74) ≈ 8.60

Next, we calculate the dot product of u and v:

u · v = (6)(7) + (4)(5) = 42 + 20 = 62

Now, we can substitute the values into the dot product formula:

62 = (7.21)(8.60) cos(theta)

Solving for cos(theta), we have:

cos(theta) = 62 / (7.21)(8.60) ≈ 1.061

To find theta, we take the inverse cosine (arccos) of 1.061:

theta ≈ arccos(1.061) ≈ 43.7 degrees

Therefore, the angle between vectors u and v is approximately 43.7 degrees to the nearest tenth of a degree.

The statement correctly describes the relationship between △DEF and △D'E'F' is option (D) △DEF is congruent to △D′E′F′ because you can map △DEF to △D′E′F′ using a reflection across the x-axis, which is a rigid motion.

In the given figure

Consider the ΔDEF

The coordinates of the each point is

D = (0,-1)

E = (-3,-4)

F = (6, -4)

The coordinates of the △D′E′F′

D' = (0,1)

E' = (-3,4)

F' = (6,4)

Here we can see that there is a reflection across the x axis which is a rigid motion

Hence, the statement correctly describes the relationship between △DEF and △D'E'F' is option (D) △DEF is congruent to △D′E′F′ because you can map △DEF to △D′E′F′ using a reflection across the x-axis, which is a rigid motion.

Answer:

9, 30, and 15.

Step-by-step explanation:

Let the three numbers be a, b, and c.

The sum of them is 54. So:

\(a+b+c=54\)

The third number is 6 more than the first. In other words, c=a+6.

The second number is twice the third. In other words, b=2c.

Let’s write the second number in terms of a. Since b=2c, this means that b=2(a+6).

Let’s substitute them into our equation. So:

\(a+2(a+6)+(a+6)=54\)

Solve for a. Distribute:

\(a+2a+12+a+6=54\)

Combine like terms:

\(4a+18=54\)

Subtract 18 from both sides:

\(4a=36\)

Hence, the value of a is:

\(a=9\)

So, the first number is 9.

The third number is 6 more than the first, so the third number is 15.

The second number is twice the third. So, the second number is 30.

Therefore, our numbers are:

9, 30, and 15.
