The driver of a car with a total of 1800 kg mass is traveling at 23 m/s when he slams on the brakes, locking the wheels on the dry pavement. The coefficient of kinetic friction between rubber and dry concrete is typically 0.7. Use the work–energy principle to calculate how far the car will travel before stopping.

Li Na is going to plant 636363 tomato plants and 818181 rhubarb plants. Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants. What is the greatest number of rows Li Na can plant?

Answers

Answer:

9 rows

Step-by-step explanation:

Given that:

Li Na wants to plant 63 tomato plants and 81 rhubarb plants

However, Li Na was hoping with the mindset to plant the plants in rows;

where each row possesses the same number of tomato plants and rhubarb plants.

So;

Suppose we choose a given number, Let's say (9) to be the divisor for both the number of tomato plants and rhubarb plants;

Then

63/9 tomato plants = 7 tomato plants

81/9 rhubarb plants = 9 rhubarb plants

Therefore, the greatest number of rows Li Na can plant 7 tomato plants and 9 rhubarb  plants = 9

Refer to the figure at the right. What percent of the
area of rectangle PQRS is shaded?
A) 12.5%
B) 25%
C) 30%
D) 40%

Answers

Step-by-step explanation:

B) 30%, if you put the two pieces together it would be 30% of the rectangle that is shaded

The percent of the area of rectangle PQRS is shaded is 25%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100.

Given:

The shape is a rectangle and it is cut into half using diagonal.

again cut by another diagonal which 1/4 section.

Now again it is one more time cutted but this time make section of 1/8

As, there are two shaded section

=1/8+1/8

=2/8

=1/4

=1/4 *100

=25%

Hence,  percent of the area of rectangle PQRS is shaded is 25%.

Which graph represents an even function?

On a coordinate plane, a hyperbola has a curve in quadrant 1 and a curve in quadrant 3. The curve in quadrant 1 has a vertex at (2, 2) and goes through points (1, 5) and (5, 1). The curve in quadrant 3 has a vertex at (negative 2, negative 2) and goes through points (negative 5, negative 1) and (negative 1, negative 5).

On a coordinate plane, a function has two curves. The first curve is asymptotic to x = negative 3, goes through (negative 2, 0), has a minimum of (negative 1.5, negative 1), goes through (negative 1, 0), and connects with the second curve at (0.5, 3). The second curve starts at (0.5, 3), goes through (2, 0), has a minimum of (2.5, negative 1), goes through (3, 0), and is asymptotic to x = 4.

On a coordinate plane, a parabola opens down. It goes through (negative 2, 0), has a vertex at (0, 4), and goes through (2, 0).

On a coordinate plane, a straight line has a negative slope. It goes through (negative 2, 4), crosses the y-axis at (0, 2), and crosses the x-axis at (2, 0).

Answers

Using the concept of even function, it is found that the graph that represents an even function is the third option, given by:

On a coordinate plane, a parabola opens down. It goes through (-2, 0), has a vertex at (0, 4), and goes through (2, 0).

--------------------------------

For an even function, [tex]\mathbf{f(x) = f(-x)}[/tex] for all values of x.

--------------------------------

For the first option, [tex]f(1) = 5[/tex], and [tex]f(-1) = -5[/tex], thus [tex]\mathbf{f(x) \neq f(-x)}[/tex], and the function is not even.For the second option, there are asymptotes, thus, it is not even.For the third option, from the information given, [tex]\mathbf{f(-2) = f(2)} = 0[/tex], we suppose this extends for all values of x, thus, it is even, and this is the correct option.For the fourth option, [tex]f(-2) = 4[/tex] and [tex]f(2) = 0[/tex], thus [tex]\mathbf{f(-x) \neq f(x)}[/tex], and the function is not even.

ABC=40 and Bd is angle bisector of ABC what is ABD= ?

Answers

Answer:

20

Step-by-step explanation:

40 ÷ 2 = 20

its 20 since BD is an angle that bisects " divdes " angles in half.

The measure of angle ABD is 20 degrees and this can be determined by using the properties of the angle bisector.

Given :

ABC = 40 and BD is the angle bisector of angle ABC.

The following steps can be used in order to determine the angle ABD:

Step 1 - According to the given data, BD is the angle bisector of angle ABC.

Step 2 - An angle bisector bisects the angle into two equal parts.

Step 3 - So, the measure of angle ABD is calculated as:

[tex]\angle ABD = \dfrac{\angle ABC}{2}\\\\ \angle ABD = \dfrac{40}{2}\\\\ \angle ABD = 20^\circ[/tex]

So, the measure of angle ABD is 20 degrees.

A cat spends 2/3 of its life asleep. If a cat lives to be 15 years old, how many years di it spend asleep?

Answers

Answer:

10 years

Step-by-step explanation:

You start by writing an equation:

(2/3) * (15) = x

x being how many years it has been asleep.

Then multiply the two numbers together:

x = 10

Answer:

10 years

Step-by-step explanation:

Divide the cats life by the denominator to find how much it sleeps for 1/3 of its life.

15  3 = 5 years

Multiply 5 by the numerator to find how much it sleeps for 2/3 of its life.

5 * 2 = 10 years

A tree in the Amazon rain forest grows an average of 2.3 cm per week. Write a sequence that represents the weekly height of the tree if it is 7 meters tall today. Write a recursive formula for the sequence and find the height of the tree after 6 weeks.

Answers

Answer:

Recursive formula

= an = a1 +(n - 1)d

Where

a1 = First term

n = nth term

d = common difference

The height of the tree after 6 weeks = 711.5 centimeters or 7.115 meters

Step-by-step explanation:

Recursive formula

= an = a1 +(n - 1)d

Where

a1 = First term

n = nth term

d = common difference

We are told that the tree is 7 meters tall today = a1

We convert to centimeters

1m = 100cm

7m =

Cross Multiply

= 7 × 100cm

= 700cm

And it grows at an average of 2.3cm per week = 2.3

Hence, an = a1 +(n - 1)d

We are to find the height of the tree after 6 weeks

a6 = 700 + (6 - 1) 2.3

a6 = 700 + (5)2.3

a6 = 700 + 11.5

a6 = 711.5cm.

We can convert to meters if we like

= 100 cm = 1 m

711.5 cm =

711.5cm/100

= 7.115m

The height of the tree after 6 weeks is 711.5 cm or 7.11 meters

That means the line goes through a point (0,5) that’s on 0 on the x axis (the ones that’s left to right) and on 5 on the y axis (the one that goes up and down). And perpendicular means it makes a right angle so it might make a t or x with the x axis.
