Answer 1

the piece-wise function is, -x - 5 when x ≠ -2

and when x = -2, the function's value is -2

what that means is when x = -4, the subfunction of -x - 5 is the one to use, because x = -4 is in that range

so f(-4) = -(-4) - 5 => f(-4) = -1.

so the function's graph look more or less like the one below, with a solid line going but with a gap at x = -2.

Step-by-step explanation:

[tex]\tt 38x+2+19x-2+15x=360[/tex]

[tex]\tt 38x+19x+15x+2-2=360[/tex] (Add similar elements)

Answers

Answer:

look at pic

Step-by-step explanation:

In the given case, the value of "x" in the given isosceles triangle is 18 degrees.

The given triangle is an isosceles triangle, which means that it has two equal sides. Let's denote the length of each equal side as "x".

To find the value of "x", we need to use the properties of an isosceles triangle. In an isosceles triangle, the base angles (the angles opposite to the equal sides) are congruent (equal in measure).

Since the base angles are congruent, we can set up the following equation: 2x + 3x + 5x = 180 degrees

Combining like terms, we have: 10x = 180 degrees

To solve for "x", we divide both sides of the equation by 10: x = 18 degrees

Therefore, the value of "x" in the given isosceles triangle is 18 degrees.

Answer:  b) 160 c) 1500

Step-by-step explanation: b) 50 + 50 + 30 + 30 = 160 c) 50 x 30 = 1500

Step-by-step explanation:

[tex]length \: of \: a \: field \: = 50m[/tex]

[tex]breadth \: of \: a \: field \: = 30m[/tex]

[tex]Perimeter \: of \: a \: field \: = ? [/tex]

(C) The design cannot have a control group because subjects are blocked by age-group.

What does a randomized block design imply?Subjects are divided into blocks based on a specific features such as age, gender, education, etc.Within each block subjects that receive treatment and does who do not are randomly assigned.The treatment in all blocks is the same. For example, if the purpose is to study the effect of medicine all treatment subjects should receive the same medicine and dose.

Give the equation of the line in point-
slope form that goes through the point
(-3,7) and is parallel to the line 4x-3y=7

Answers

Answer:

[tex]y-7=\frac{4}{3} (x+3)[/tex]

Step-by-step explanation:

Hi there!

We are given the point (-3, 7)

We want to write the equation of the line containing that point, in point slope-form, and that is also parallel to 4x-3y=7

Parallel lines contain the same slope

So first, let's find the slope of 4x-3y=7

To do that, we can convert the line from standard form (ax+by=c) to slope-intercept form (y=mx+b, where m is the slope, and b is the y intercept)

To do that, we need to isolate y on one side

So start by subtracting 4x from both sides

4x-3y=7

-4x      -4x

________________

-3y=-4x+7

Divide both sides by -3

y=[tex]\frac{4}{3}x[/tex]- [tex]\frac{7}{3}[/tex]

Since 4/3 is in the place of where m should be, the slope of the line is 4/3

It is also the slope of our new line, which we are trying to find

As stated earlier, we want to write this line in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point

This is where the point we were given earlier comes in. We simply need to substitute our values (of the point and the slope) into the formula to find the equation.

First, with the slope; substitute 4/3 as m in the equation

[tex]y-y_1=\frac{4}{3} (x-x_1)[/tex]

Now substitute -3 as [tex]x_1[/tex] in the equation

[tex]y-y_1=\frac{4}{3} (x--3)[/tex]

We can simplify this to:

[tex]y-y_1=\frac{4}{3} (x+3)[/tex]
Now substitute 7 as [tex]y_1[/tex] into the equation

[tex]y-7=\frac{4}{3} (x+3)[/tex]

Hope this helps!

Find the minimum distance from the parabola x-y^2=0
to the point (0,3).

Answers

Answer:

  √5

Step-by-step explanation:

The distance from the given point to the curve can be found using the distance formula. The resulting expression can be minimized to find the minimum distance.

  d = √((x2 -x1)² +(y2 -y1)²)

__

Point on the Parabola

A point on the parabola can be described by ...

  x -y² = 0

  x = y² . . . . . add y²

Then a point on this curve is ...

  (y², y)

Distance to Given Point

The distance to it from (0, 3) is ...

  d = √((0 -y²)² +(3 -y)²) = √(y⁴ +y² -6y +9)

Find the Minimum

The distance will be minimized when the derivative of the radical expression is zero:

  d(y⁴ +y² -6y +9)/dy = 0 = 4y³ +2y -6

  0 = 2y³ +y -3 . . . . . . . . remove a factor of 2

This will have a rational root in the set {±1, ±3}.

Trial and error shows that y=1 is the only real solution to this equation.

__

Then the minimum distance is ...

  d = √(1⁴ +1² -6·1 +9) = √5

_____

Additional comment

The attached graph shows that a circle with radius √5 centered at (0, 3) will intersect the parabola at exactly one point. That confirms our solution.
