Step-by-step explanation:

Answer:

best option is A

Step-by-step explanation:

This represents the distance that Mr. Stein drove, given that Mr. Smith drove x miles. The value of x must be between 0 and 140, since Mr. Smith cannot drive more than 140 miles and less than 0 miles.

An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. It can be simplified, evaluated, or manipulated using algebraic rules and properties.

Let x be the number of miles Mr. Smith drove. Then, the number of miles Mr. Stein drove is \(140 - x\)  , since they drove a total of 140 miles and Mr. Smith already drove x miles.

the algebraic expression for how many miles Mr. Stein drove is:

\(140 - x\)

Therefore, This represents the distance that Mr. Stein drove, given that Mr. Smith drove x miles. The value of x must be between 0 and 140, since Mr. Smith cannot drive more than 140 miles and less than 0 miles.

(i) Every entry not on the diagonal of \(P^2\) must be 0. For instance, the (1, 2)-th entry in \(P^2\) is

\(\begin{pmatrix}-\dfrac12&a&a\end{pmatrix}\begin{pmatrix}a\\-\dfrac12\\a\end{pmatrix} = -a+a^2\)

All other non-diagonal entries have the same value. Then

\(-a+a^2 = a(a-1) = 0 \implies \boxed{a=0 \text{ or }a=1}\)

Meanwhile, the diagonal entries are

\(\begin{pmatrix}-\dfrac12&a&a\end{pmatrix}\begin{pmatrix}-\dfrac12\\a\\a\end{pmatrix} = \dfrac14+2a^2\)

(ii) Since \(P^2\) is diagonal, the determinant is simply the product of the entries along the diagonal. If a = 0, these entries are each 1/4, so that

\(|P^2| = \left(\dfrac14\right)^3 = \boxed{\dfrac1{64}}\)

If a = 1, they are 9/4, so that

\(|P^2| = \left(\dfrac94\right)^3 = \boxed{\dfrac{729}{64}}\)

(a). The graph of y = -f(x) is shown in the image below.

(b). The graph of y = g(-x) is shown in the image below.

By reflecting the parent absolute value function g(x) = |x + 2| - 4 over the x-axis, the transformed absolute value function can be written as follows;

y = -f(x)

y = -|x + 2| - 4

Part b.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = rise/run

Slope (m) = -2/4

Slope (m) = -1/2

At data point (0, 5) and a slope of -1/2, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 5 = -1/2(x - 0)

g(x) = -x/2 + 5, -4 ≤ x ≤ 4.

y = g(-x)

y = x/2 + 5, -4 ≤ x ≤ 4.

Answer:

x ≤ 3

Step-by-step explanation:

Answer:

The value of x is 2.

Step-by-step explanation:

The key to this solution is to combine like terms.

2x-3 > 11-5x

There are lots of ways to combine them but the way I think would be the most simple would be to avoid negative numbers (although I personally enjoy it) but anyways,

First, you can add 5x to both sides of the inequality.

This would cancel out 5x and leave you with: 7x-3 > 11

The next terms that you can combine can be the constants. You can combine -3 and 11 and to do that, you add 3 on both sides. That would cancel 3 out and leave you with: 7x > 14

Now, the last step is to get x by itself and to do that, you divide 7 on both sides to get:

x > 2

Triangles in Geometry

Step-by-step explanation:

The value of y is 4√3

Similar triangles have the same corresponding angle measures and proportional side lengths. The corresponding angles of similar triangles are congruent or equal.

Also , the ratio of corresponding sides of similar triangles are equal.

There are two triangles that are similar

Therefore;

y /16 = 4/y

The amount of work done is Option A) 12 N/m

Work done is simply defined as the product of the magnitude of displacement, (d) and the component of the force that in the direction of displacement.

It measures energy transfer that occurs when an object is moved to a distance by an external force which is applied in the direction of the displacement.

Work done on a body is equivalent  to the increase in the energy of the body, because it transfers energy to the body.

The formula for work done is;

W = fd

Where, 'f' is the applied force and d is the distance

Substitute the values

Work done = 6(2)

Answer:

f(3) = 425

f(3) is the elevation of a mountain climber after 3 hours of climbing.

Step-by-step explanation:

So we are given a line that relates time to elevation. We are also given that the equation of the line is f(x) = 125x + 50. From looking at the graph given, we can see that x is the time, in hours, and y, or f(x), is the height, in feet. We are asked to find f(3) and interpret it's meaning.

To find f(3), we would have to find what f(x) is when x = 3. To do this, lets plug in 3 for x into the given equation:

f(3) = 125(3) + 50 = 425

So f(3) = 425. Now, we already know that x is the time in hours and y, or f(x), is the elevation in feet. We set x to 3 when solving for f(3). We have also found that f(3), or y when x = 3, is 425. So f(3), or 425, is the elevation after 3 hours.

We will have the following:

A. The function is compressed in the y-axis by a factor of 0.5 and then it is inverted in its direction; since it is a line the line is then decreasing instead of increasing.

B. The function is increased by a factor of 2 in the y-axis and then it is moved 3 units up:

C. The function is increased by a factor of 5/3 (Approximately 1.67) in the y-axis and then it is made so it is no longer increasing, but decreasing:

D. The function is increased in the y-axis by a factor of 9 and then it is moved 9 units down:

The amount obtained after 1 year from the whole property is obtained as $27866.82.

The compound interest is can be considered as a case when the interest is added for every interval of time.

The amount for the previous interval becomes the principal for the current one.

The total rent for 9 condos = 9 × 1300 = $11700.

The rate of interest is 7.5% monthly.

Total time = 1 year = 12 months.
The given problem is the case of compound interest for which the expression is given as follows,

A = P(1 + r/100)ⁿ

Substitute the corresponding values to obtain,

A  = 11700(1 + 7.5/100)¹²

    = 27866.82

The arc length of \(y=2x^{\frac32}\) over [0, 1] is given by the integral,

\(L=\displaystyle\int_0^1\sqrt{1+\left(\frac{\mathrm dy}{\mathrm dx}\right)^2}\,\mathrm dx\)

Differentiate y with respect to x using the power rule:

\(\dfrac{\mathrm dy}{\mathrm dx}=\dfrac32\times2 x^{\frac32-1}=3x^{\frac12}\)

Then the integral becomes

\(L=\displaystyle\int_0^1\sqrt{1+\left(3x^{\frac12}\right)^2}\,\mathrm dx=\int_0^1\sqrt{1+9x}\,\mathrm dx\)

Substitute u = 1 + 9x and du = 9 dx :

\(L=\displaystyle\int_0^1\sqrt{1+9x}\,\mathrm dx=\frac19\int_1^{10}\sqrt u\,\mathrm du\)

\(L=\displaystyle\frac19\left(\frac23u^{\frac32}\right)\bigg|_1^{10}\)

\(L=\dfrac2{27}\left(10^{\frac32}-1^{\frac32}\right)\)

\(L=\boxed{\dfrac2{27}\left(10^{\frac32}-1\right)}\)
