Boubacar launches a toy from a platform. The graph below shows the height of the rocket ‘h’ in feet after ‘t’ seconds. What is the rocket’s initial height?

Answer:

the answer will be : 1.13

Answer:

Step-by-step explanation:

First, since 50 people can go per trip and the plane wants to fly a lot of times to carry 25,000 people.

Second, then you have to do 25,000/50

Thirdly, you have to find the awnser

Equation for the given pair of lines which are perpendicular to each other and intersect at the point (-3 , -7 ) are :

( y + 7 ) = m₁ ( x + 3) and ( y + 7 ) = (-1 / m₁ )( x + 3 )

As given in the question,

Pair of equations that are perpendicular to each other and intersect at point ( -3 , -7 ) are as follow:

let us consider slope of perpendicular lines are m₁ and m₂.

Product of the slope of perpendicular lines = -1

⇒ m₁ × m₂ = -1

⇒ m₂ = -1 / m₁

Pair of perpendicular intersect at point ( -3 , -7 ) .

Required equation of perpendicular lines is given by :

For line 1:

( y - (-7)) / ( x - (-3) ) = m₁

⇒ y + 7 = m₁ (x+3)  

For line 2:

( y - (-7)) / ( x - (-3) ) = m₂

⇒ y + 7 =  m₂( x+ 3)

⇒  y + 7 =  -1 / m₁ ( x+ 3)

Therefore, equation for the given pair of lines which are perpendicular to each other and intersect at the point (-3 , -7 ) are :

( y + 7 ) = m₁ ( x + 3) and ( y + 7 ) = (-1 / m₁ )( x + 3 )

Answer:

8 inches

Step-by-step explanation:

1 foot is 12 inches

20 - 12 = n

n = 8

Answer:  The correct answer is 8 more inches.

Step-by-step explanation:

The puppys' current height is 12 inches (1 foot)

The vet's advised maximum height is 20 inches

Difference in height = 20 - 12 = 8 inches

The population of the deer in year 2018 would be 11971.

Given,

In the question:

The model is used to estimate the deer population in a region, where x is the number of years after the year 2009. Using the model, estimate the deer population in the year 2018

Model is given as:

P = 2,3201 [tex](1.2)^x[/tex]

Now, According to the question:

The number of years from 2009 to 2018 = 9

Here, the equation that shows the deer population after x years since 2009,

P = 2,3201 [tex](1.2)^x[/tex]

Substitute x=9 in the above equation,

P = 2,3201[tex](1.2)^9[/tex]

P = 2320(5.15978)

P ≈ 11971

Hence,  the population of the deer in year 2018 would be 11971.

Answer:

$238.26

Step-by-step explanation:

The solution for the linear equation:

x - (2/3)*x - (1/2) = (1/3) + (5/6)*x

Is x = -5/3

Is hard to understand what you wanted to write, but I assume that the linear equation that we need to solve is:

x - (2/3)*x - (1/2) = (1/3) + (5/6)*x

To solve this linear equation, we need to isolate the variable x in one of the sides of the equation

To do so, we move all the terms with "x" to the left side and the terms without to the right side:

x - (2/3)*x - (5/6)*x = 1/3 + 1/2

Now we solve this:

x - (4/6)x - (5/6)x = 2/6 + 3/6

x - (9/6)*x = 5/6

We can write the "1" in the first term as 6/6

(6/6)*x - (9/6)*x = 5/6

(-3/6)*x = 5/6

-3x = 5

x = 5/-3

x = -5/3

That is the solution of the linear equation.

The equations that are true for x = –2 and x = 2 include the following:

x² – 4 = 0

4x² = 16

In order to determine which x-values are true solutions based on the given equations, we would have to test each of the x-values by substituting their values into the equations as follows;

When x = -2, we have:

x² – 4 = 0

(-2)² – 4 = 0

4 - 4 = 0 (True).

When x = 2, we have:

x² – 4 = 0

(2)² – 4 = 0

4 - 4 = 0 (True).

When x = -2, we have:

x² = -4

(-2)² = -4

4 = -4 (False).

When x = -2, we have:

3x² + 12 = 0

3(-2)² + 12 = 0

3(4) + 12 = 0

12 + 12 = 0

24 = 0 (False).

When x = -2, we have:

4x² = 16

4(-2)² = 16

4(4) = 16 (True).

When x = 2, we have:

4x² = 16

4(2)² = 16

4(4) = 16 (True).

When x = -2, we have:

2(x – 2)² = 0

2(-2 – 2)² = 0

2(-4)² = 0

2(16) = 0

32 = 0 (False).

When x = 2, we have:

2(x – 2)² = 0

2(2 – 2)² = 0

2(0) = 0 (True).

The equations that represent the circle having a diameter of 12 units and a center lying on y-axis are; x² + (y – 3)² = 36, and x² + (y + 8)² = 36.

The standard form of the equation of a circle is (x - h)² + (y - k)² + r², where (h, k) is the center of the circle, and r is its radius.

We have given that circle having a diameter of 12 units, will have a radius of 12/2 = 6 units. Thus, r = 6.

Since we know that circle having the center on the y-axis will have a center as (0, k) as all points on the y-axis have x-coordinate 0.

Thus, the equation of the circle, with a diameter of 12 units is;

x² + (y - k)² = 6², or,

x² + (y - k)² = 36.

From the given options, the equations x² + (y – 3)² = 36, and x² + (y + 8)² = 36, are correct.

Thus, the equations that represent the circle having a diameter of 12 units and a center lying on y-axis are; x² + (y – 3)² = 36, and x² + (y + 8)² = 36.

Step-by-step explanation:

Ratio:

Find the quantity of yellow and red dye in the mixture.

 Yellow : Red = 9 : 2

 Total share = 9 + 2 = 11

    [tex]\sf \text{Quantiy of yellow} = \dfrac{9}{11}*44[/tex]

                                 = 9 * 4

                                = 36 litres

      [tex]\sf \text{Quantity of Red}= \dfrac{2}{11}*44[/tex]

                                  = 2 * 4

                                  = 8 litres.

Now, 8 litres of red dye is added.

New quantity of red dye = 8 + 8 = 16 liters.

New ratio of Yellow to red = 36 : 16

                                             = (36÷4) : (16÷4)

Answer:

x = 17

Step-by-step explanation:

(5x - 23) and (7x - 1) are same- side interior angles and sum to 180° , so

5x - 23 + 7x - 1 = 180

12x - 24 = 180 ( add 24 to both sides )

12x = 204 ( divide both sides by 12 )

x = 17

The ordered pair that made the equation, y = 4x - 5 correct is (5, 15).

Mara's age is 5 less than four times Brandy's age.   Let x represent Brandy's age, and let y represent Mara's age.

Therefore, the ages can be represented linearly as follows:

y = 4x - 5

where

Therefore, the ordered pair (x, y) that makes the equation correct can be computed as follows:

y = 4x - 5

y = 4(5) - 5

y = 20 - 5

y = 15

The number of people who do not like any of the three colour is 5, using the set theory.

What is Set theory?

A subfield of mathematics called set theory studies sets and their characteristics. Set theory's fundamental ideas are straightforward and seem to stand on their own. The set theory appears to be straightforward, but it is actually a very complex topic. Mathematicians have specifically demonstrated how almost all mathematical ideas and conclusions may be formalized within the theory of sets. This is regarded as one of the pinnacles of contemporary mathematics. Given this accomplishment, it is possible to assert that set theory serves as the foundation for mathematics.

In the given question, we have:

Total number of people in the survey = 25;

Number of people like red = 13;

The number of people who like blue = 8;

The number of people who like yellow = 13;

5 people like both Red & Blue,

4 people like both Blue & yellow,

7 people like both Red & Yellow

2 people like all three colors.

Let n be the number of people who do not like any of the three colour.

Using the concept of set theory, we can write it as:

3 + 4 + 1 + 5 + 2 + 3 + 2 + n = 25;

⇒20 + n = 25;

n = 25 - 20

n = 5;
