Altitude (AB) = 6cm

Base (BC) = 8cm

Hypotenuse (AC) = ?

[tex] \fbox \text{According To Pythagoras Theorem = }[/tex]

[tex] \text{(Hypotenuse)² = (Altitude)² + (Base)²}[/tex]

Inserting The Values

[tex] \text{(Hypotenuse)²} =( {6})^{2} + (8) {}^{2} [/tex]

[tex] (\text{AC}) {}^{2} = (6) {}^{2} + (8) {}^{2} \\ \implies \text{(AC)} {}^{2} = 36 + 64 \\ \implies\text{AC} = \sqrt{100} \\ \implies\text{AC} = 10 \\ \\ \therefore \text{Hypotenuse (AC)} = 10 \text{cm}[/tex]

Correct Option D= 10cm

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!

Recall that cos(x + y) = cos(x) cos(y) - sin(x) sin(y). So

cos(420°) = cos(360° + 60°)

cos(420°) = cos(360°) cos(60°) - sin(360°) sin(60°)

cos(420°) = cos(60°)

since cos(360°) = 1 and sin(360°) = 0. Then

cos(420°) = cos(60°) = 1/2

Answer:

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:

  √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)

__

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)

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

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

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

A = 16(17)

A = 272

3a. A = 1/2(29)(24)

Answer:

Step-by-step explanation:

Since its a positive translation you add 3 to 1 because you are going to the right. You coordinates of that step then becomes (4,-3). Then you need to translate up 6 units. Because the y is -3 you add 3 to make 0, then 3 more (3+3=6) to get positive 3. You then end up with the coordinates (4,3)
