Answer:

$\sqrt{13}$

Step-by-step explanation:

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$\mathrm{The\:distance\:between\:}\left(-4,\:-3\right)\mathrm{\:and\:}\left(-2,\:0\right)\mathrm{\:is\:}$

$=\sqrt{\left(-2-\left(-4\right)\right)^2+\left(0-\left(-3\right)\right)^2}$

Answer:

Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 + x – 1

Step-by-step explanation:

The answer is A because the axis of symmetry is in between 0 and 1, the vertex lies on 0.5 and -0.75, and the parabola opens down so the coefficient of a is -1, and the y-int or the value of c is -1

The vertex of the function is axis of symmetry is and the formula for the function is Option (a) is correct.

Further Explanation:

Given:

Calculation:

The standard form of the parabola is shown below.

Here, the parabola has vertex at and has the symmetry parallel to x-axis and it opens left.

The general form of the parabola can be expressed as follows,

The graph is a downward parabola.

From the graph it has been observed that the vertex of the parabola is

Symmetry of the graph is

The -intercepts of the graph is Therefore, the value of is

The value of is -1 as the graph is a downward parabola.

The vertex of the function is axis of symmetry is and the formula for the function is Option (a) is correct.

Lauren's house is 30 feet wide. its length is 2 1/2 times its width. how long is lauren's house?

galina1969 [7]

You are trying to solve the length of the house. Let x equal the length of the house. The length of the house is 2 1/2, or 2.5 times its width. The width of the house is 30 feet.

Your equation should look like this:
x = 30(2.5)

Mutiply 30 ft. times 2.5 to get 750 ft.

x = 750 ft.

Don't forget to use your unit of measurement in the answer! You are working in feet.

If AD is the altitude to BC, what is the slope of AD?

anygoal [31]

Answer:

Option (C)

Step-by-step explanation:

If AD is the altitude to BC, both the segments AD and BC will be perpendicular to each other.

By the property of perpendicular lines,

$m_1\times m_2=-1$

where $m_1$ is the slope of the line AD and $m_2$ is the slope of BC.

$m_2=\frac{y_2-y_1}{x_2-x_1}$

$=\frac{8+2}{3-7}$

$=-\frac{5}{2}$

Now from the given property,

$m_1\times (-\frac{2}{5})=-1$

$m_1=\frac{5}{2}$

Therefore, slope of altitude BC = $\frac{5}{2}$

Option (C) will be the answer.

Each of the 4 family members uses 175 or fewer minutes of their combined family cell phone plan. At the end of the month, the fa

miskamm [114]

Answer:

The family might share maximum of 700 mins each month.

Step-by-step explanation:

Given:

Total number of minutes used by each member = 175

Number of members in family = 4

We need to find the number of minute family will share each month.

Solution:

Let the number of minute family will share each month be 'x'.

So we know that;

Total number of minute family will share each month should be less than or equal to Total number of minutes used by each member multiplied by Number of members in family

framing in equation form we get;

$x\leq 175\times4\\\\x\leq 700 \ mins$

Hence The family might share maximum of 700 mins each month.
