Answer 1

Answer:

Step-by-step explanation:

distribute the x and solve

Answer 2

The value of x is 8 in.

What is a prism?

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

Length = x + 4

Width = x

Height = x - 2

The volume of the rectangular prism = 385 in³

The volume of the rectangular prism = length x width x height

Now,

length x width x height = 385

(x + 4) x (x - 2) = 385

(x + 4) (x² - 2x) = 385

x³ - 2x² + 4x² - 8x = 385

x³ + 2x² - 8x = 385

This is a cubic polynomial.

f(x) = x³ + 2x² - 8x - 385

f(x) = a³ + bx² + cx + d = 0

Using the calculator we get,

Roots:

x = -3.20181 + 5.96339 i (rejected)

x = -3.20181 - 5.96339 i (rejected)

x = 8.40362 = 8

Thus,

The value of x is 8 in.

Answers

Answer:

24 trillion miles. The nearest-known exoplanet is a small, probably rocky planet orbiting Proxima Centauri – the next star over from Earth. A little more than four light-years away, or 24 trillion miles.

The number of miles in 4.25 light-years will be 24.986 × 10¹² miles.

What is conversion?

Conversion means to convert the same thing into different units.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The nearest-known exoplanet from the earth is 4.25 light-years away.

We know that 1 lightyear = 5.879 × 10¹² miles.

Then the number of miles in 4.25 light-years will be

⇒ 4.25 light-years

⇒ 4.25 × 5.879 × 10¹² miles

⇒ 24.986 × 10¹² miles

The number of miles in 4.25 light-years will be 24.986 × 10¹² miles.

Replace y with x

x = y² - 38

Add 38 to both sides of the equation

x + 38 = y² - 38 + 38
y² = x + 38

Take the square root of both sides

√y² = ±√x + 38

y =  ±√x + 38

about 25 miles at 29° south of east
about 29 miles at 25° south of east
about 25 miles at 29° south of west

Answers

By finding the magnitude and bearing, we conclude that the correct option is:

"about 29 miles at 25° south of west"

How to write the vector in polar coordinates?

For a vector (x, y), the polar coordinates are the magnitude R and the bearing θ.

Such that:

[tex]R = \sqrt{x^2 + y^2} \\\\\theta = Atan(y/x)[/tex]

In this case, the original vector is (-26, -12), replacing that we get:

[tex]R = \sqrt{(-26)^2 + (-12)^2} = 28.6 \\\\\theta = Atan(-12/-26) = 24.7\°[/tex]

Where the angle is measured from the negative x-axis counterclockwise, so it is South of West.

Then we can describe this vector as:

"About 29 miles at 25° south of west".

The first option is the correct one.

If the perimeter of a pool is 102ft, and the length is 6 more than twice the width, what are the dimensions?

Answers

Answer:

Length = 36 ft
Width = 15 ft

Step-by-Step Explanation:

Let length of pool be ‘x’ ft
Let width of pool be ‘y’ ft
Perimeter = 2(x + y) = 102 ft

By Given:

2(x + y) = 102
=> 2x + 2y = 102 (Eq. 1)

=> x = 2y + 6 (Eq. 2)

Substitute value of ‘x’ from Eq. 2 in 1 :-

2x + 2y = 102
2(2y + 6) + 2y = 102
4y + 12 + 2y = 102
6y + 12 = 102
6y = 102 - 12 = 90
=> y = 90/6 = 15

Therefore, y = 15

Substitute value of ‘y’ in Eq. 2 :-

x = 2y + 6
x = 2(15) + 6
x = 30 + 6
=> x = 36

Therefore, x = 36

Verification:

2x + 2y = 102
2(36) + 2(15) = 102
72 + 30 = 102
=> 102 = 102
LHS = RHS

Therefore,
Length (x) = 36 ft
Width (y) = 15 ft

no, no, you use the equation to identify a, b and c.

then you use the formula with these values to get the solutions to the equation (the values of x for which the equation delivers 0).

always remember, a quadratic equation always has 2 solutions. sometimes at least one of them are not a real number, sometimes the 2 springs are equal, ...

x² - 4x - 2 = 0

a, b, c are the factors of the terms in x and the constant term.

so,

a = 1

b = -4

c = -2

x = (-b ± sqrt(b² - 4ac))/(2a)

x = (4 ± sqrt((-4)² - 4×1×-2))/(2×1) =

= (4 ± sqrt(16 + 8))/2 = (4 ± sqrt(24))/2 =

The average velocity: _ ft/sec
The instantaneous velocity equals to the average velocity at t = _ sec

Answers

The average velocity of the object after during the first three seconds is: 48m/s

The time at which the instantaneous velocity equals the average velocity within the first three seconds is 1.5 seconds.

What is instantaneous and average velocities?

Instantaneous velocity  is the speed of an object at a particular point in time.

Average velocity is the velocity of an object after covering a certain distance for a period of time

Analysis:

Given

initial height = 600 feet

Height with respect to time = f(t) = -16[tex]t^{2}[/tex] + 600

a) Height at t = 0 = 600 feet

    Height at t = 3 seconds = f(3) = -16[tex](3)^{2}[/tex] + 600 = 456 feet

Distance travelled  = 600 - 456 = 144 feet

Average velocity = distance travelled/time taken  = 144/3 = 48 feet/seconds

b) instantaneous velocity at time t = [tex]\frac{df(t)}{dt}[/tex] = [tex]\frac{d(-16t^{2} + 600) }{dt}[/tex] = -32t

  when instantaneous velocity equal average velocity

     -32t = -48

      t = 1.5 seconds

In conclusion, the Average velocity after 3 seconds is 48 feet per seconds and the time taken for the average velocity to equal the instantaneous velocity is 1.5 seconds.
