79=11x+13
Solve each equation by using the properties of equality and justify each step

Answers

Solution: X=6

Detailed explanation:

In this problem we're asked to find "x" or the unknown.

The first step is to subtract 11x from both sides.

[tex]---\mapsto\boldsymbol{-11x+79=13}[/tex]

Next, subtract 79 from both sides.

[tex]---\mapsto\boldsymbol{-11x=-66}[/tex]

To finish this off, divide both sides by -11.

[tex]---\mapsto\boldsymbol{x=6}[/tex]

Voila! There's our answer!

As x approaches negative infinity, approaches negative infinity.

Answers

The statement that is true about this function is C. As x approaches positive infinity, h(t) approaches positive infinity

Calculations and Parameters

Given that we have:

The domainThe rangeThe function

Therefore, when x approaches to negative infinity,

[tex]\lim_{x \to \infty} h(x)[/tex]

= 2^(-∞-5)

= 2^(-∞)

Also, as x approaches negative infinity, function h(x) approaches 0.

Then when x approaches to positive infinity,

the transformations used are:

Dilation of scale factor 5.Shift of 2 units to the right.Shift of 3 units up.

Which transformations are used?

We start with the function:

[tex]f(x) = 2^x[/tex]

And we have the transformed function:

[tex]g(x) = 5*2^{x-2} + 3[/tex]

Bow, let's start with the original function f(x). If first we apply a vertical dilation of scale factor 5, then we have:

g(x) = 5*f(x).

Then we apply a shift of 2 units to the right, so we have:

g(x) = 5*f(x - 2)

Then we apply a shift of 3 units up, so we have:

g(x) = 5*f(x - 2) + 3

Replacing f(x) by the actual function:

[tex]g(x) = 5*2^{x-2} + 3[/tex]

Answers

The bearing from C to A of the given travel path is gotten as; 100.63°

How to calculate the bearing?

From the bearing image attached, we can use trigonometric ratios to get;

tanx = opp/adj

x = 53 + θ ---------- eqn(1)

opp = 119

adj = 59

Thus;

tan x = 119/59

tan x = 2.0169

x = tan⁻¹(2.0169)

x = 63.63°

From eqn (1), we have;

θ = x - 53

θ = 63.63 - 53

θ = 10.63°

Thus, the bearing from C to A = 90 + 10.63 = 100.63°

Find the probability that a student earns

p=[?]

Answers

Answer:

The probability that a student earns a grade of A is 1/7.

Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:

P(E) = n(E) / n(S)

As the total number of students = n(S) = 35

Students getting the grade A = n(E) = 5

So, the probability that a student earns a grade of A:

                     P(E) = n(E) / n(S)

                             = 5/35

                             = 1/7

Hence, the probability that a student earns a grade of A is 1/7.

The potential energy stored in the compressed spring of a dart gun, with a spring constant of 62.00 N/m, is 0.940 J. Find by how much is the spring is compressed.b. A 0.010 kg dart is fired straight up. Find the vertical distance the dart travels from its position when the spring is compressed to its highest position.c. The same dart is now fired horizontally from a height of 4.70 m. The dart remains in contact until the spring reaches its equilibrium position. Find the horizontal velocity of the dart at that time.d. Find the horizontal distance from the equilibrium position at which the dart hits the ground.
