If beaver family one can cut down and 20" tree in 15 minutes and family two can cut down a tree 3 times the size in twice as long how long will it take the second beaver family to cut down a 20" tree

Answers

Answer:

10 minutes

Step-by-step explanation:

Beaver family 2 can cut down 60'' (20 x 3) tree in 30 (15 x 2) minutes

In one minute, beaver family 2 would cut down 60/30 = 2'' tree

time to cut down 20'' tree = 20/2 = 10 minutes

Find the equation of the straight line having a slope root 3 and passing through the point(-1,5)​

Answers

Given:

Slope of a straight line is [tex]\sqrt{3}[/tex].

The line passing through the point (-1,5).

To find:

The equation of the straight line.

Solution:

The point slope form of a line is:

[tex]y-y_1=m(x-x_1)[/tex]

Where, m is the slope and [tex](x_1,y_1)[/tex] is the point.

The line passing through the point (-1,5) with slope [tex]\sqrt{3}[/tex]. So, the equation of the line is:

[tex]y-5=\sqrt{3}(x-(-1))[/tex]

[tex]y-5=\sqrt{3}(x+1)[/tex]

[tex]y=\sqrt{3}x+\sqrt{3}+5[/tex]

Therefore, the equation of the straight line is [tex]y=\sqrt{3}x+\sqrt{3}+5[/tex].

3. A circle with center (0,0) has a y-intercept at (3,0).
Find the equation of the circle.

Answers

Answer:

x^2 + y^2 = 9

Step-by-step explanation:

The standard equation of a circle with center at (h, k) and radius r is

(x - h)^2 + (y - k)^2 = r^2.  Here h = 0, k = 0, x = 3 and y = 0:

(3 - 0)^2 + (0 - 0)^2 = r^2, or

9 = r^2.  Thus, the radius is 3.

The equation of this circle is (x - 0)^2 + (y - 0)^2 = 9, or

x^2 + y^2 = 9

Answer:

1 - G;

2 - R;

3 - E;

4 - D;

5 - T;

6 - J;

7 - O;

8 - B;

Step-by-step explanation:

The formula for calculating the sum of interior angles is ( n − 2 ) * 180 ∘ where n is the number of sides.

1) (4 - 2) * 180 = 360 therefore X + 100 + 118 + 53 = 360  =>  X = 360 - 100 - 118 - 53 = 89   =>   X = 89

2) (5 - 2) * 180 = 540  => 90 + 90 + X + 128 + X = 540 => 2*X = 540 - 90 - 90 - 128 = 232   =>   X = 116

3) (6 - 2) * 180 = 720 => 101 + 126 + X + 96 + 147 + 135 = 720 => X = 720 - 101 - 126 - 96 - 147 - 135 = 115   =>   X = 115

4) (9 - 2) * 180 = 7 * 180, since all angles are equal the answer is 7 * 180 / 9 = 7 * 20 = 140    =>   X = 140

5) (5 - 2) * 180 = 540 => 90 + 131 + 102 + X + 145 = 540 => X = 540 - 90 - 131 - 102 - 145 = 72   =>   X = 72

6) Since the sum of the linear pair angles equal 180, X = 180 - 70 = 110 => X = 110

7) (4 - 2) * 180 = 360; Linear pair angle for 73 is 180 - 73 = 107, that means X + 102 + 39 + 107 = 360  =>  X = 360 - 102 - 39 - 107 = 112   =>   X = 112

8) (5 - 2) * 180 = 540;  Linear pair angle for 84 is 180 - 84 = 96;  Linear pair angle for 79 is 180 - 79 = 101;  Linear pair angle for 34 is 180 - 34 = 146; so X + 90 + 96 + 101 + 146 = 540   =>   X = 540 - 90 - 96 - 101 - 146 = 107  => X = 107

Write a rule in function notation to describe the transformation that is a reflection across the x-axis.

Answers

Answer:

R(x, y) = (x, -y)

Step-by-step explanation:

When we have a reflection across some line, the distance between the original point and the reflected point to the line is invariant.

For a reflection around the x-axis, the x-value is invariant, then the only value that can change is the y-value.

So if we have a point like (4, 7)

Which is at a distance of 7 units to the x-axis, the only other point that is also at a distance of 7 units to the x-axis that has the same x-value is (4, -7)

Here we already can see the rule.

If we have a point (x, y), the reflection across the x-axis gives us the point (x. -y)

Then we can write this reflection as a function in the next way:

R(x, y) = (x, -y)

This means that if the input is the point (x, y), the output is the point (x, -y)

Using Pythagoras Theorem:

In triangle ABC,
