4 lb or less ------> is less than 20 lb ------> 120

5-9 lb------------> is less than 20 lb -------> 222

10-14 lb -------> is less than 20 lb ------->378

15-19 lb ------> is less than 20 lb-------> 256

Adds the number of passenger

1) In this question let's calculate the sin(θ) and cos(θ)

Given that

2) In this question, we're calculating the value of the sine and the cosine in radians.

We must remember that 5π/4 ⇒ to 225º, and that it's in the Quadrant III

If we subtract

225 -180 =45 So the sine of 5π/4 is -√2/2 and the cosine (5π/4 ) = -√2/2

2.3) The sign of the Quadrant

Since 225º is in Quadrant III both results are negative ones.

When a, b, c changes from -1 to +1, the parabolas opens and widens.

Given,

The quadratic function, f(x) = ax² + bx + c

We have to find the change in graph when a, b, c changes from -1 to 1.

First lets consider:

a and b as constants and c is varying.

That is,

x² + x + c

Then,  the parabola will move up and down.

Now, lets consider:

a and c as constants and b is varying.

That is,

x² + bx + 1

Then, the vertex will move but  all parabolas passes through the points (0, c)

Now, we can move to the question.

What happens to graph when +1 changes to -1.

So,

b and c should keep constant and a is varying.

Then,

ax² + x + 1

Here, the parabolas opens and widens.

That is,

When a, b, c changes from -1 to +1, the parabolas opens and widens.

part A. We are given that a hiker will increase the distance covered by 10% each day. Let "S" be the distance, then on the first day the distance is:

On the second day, we must add 10% of the first day, we get:

Simplifying we get:

On the third day, we add 10% of the second day, we get:

On the fourth day, we add 10% of the third day, we get:

If we continue this pattern and we set "n" as the number of days, then a formula for the distance after "n" days is:

Now, we are given that for n = 7 the distance is 75897, therefore, we substitute n = 7 in the formula:

Substituting the value of the distance:

Now we can solve for S1, we do that by dividing both sides by 1.1 together with its

Answer:

Explanation:

Here, we want to get the number that could be inserted into the parentheses to make it true

From the logical operator given, we can see that we need a number greater than -10

From the options given, only -3 is greater than -10, which makes it the correct answer choice

In this case, we'll have to carry out several steps to find the solution.

Step 01:

8x - 3x + 4x = -36

x = ?

Step 02:

We must apply the algebraic rules to find the solution.

8x - 3x + 4x = -36

12x - 3x = - 36

9x = - 36

x = - 36 / 9

x = - 4

Answer:

60 degrees

Step-by-step explanation:

Total of angles of a triangle is 180

180-76-44= 60

To perform a two column proof, we should give a statement and give a reason of it.

So we start with the initial statement.

1. Statement: x-4 =(1/2)(8x+6)+4x. Reason: Given

Next, we distribute the multiplication (1/2) with(8x+6). If we do so, we get the following statement.

2. Statement x-4 = (4x+3) + 4x. Reason: Distributive property of addition and multiplication.

Now, on the right we can add 4x with 4x, due to the associative property of additon, we get

3. Statement: x-4 = (4x+4x)+3 = 8x+3. Reason: Associative property of addition.

Now, we can subtract x on both sides, so we get

4. Statement: -4 = 7x+3. Reason: Subtraction property of equality.

By the same reason, we should subtract 3 on both sides. We get

5. Statement: -7 = 7x. Reason: Subtraction property of equality.

Finally, we divide by 7 on both sides, so we get

6. Statement: -1=x. Reason: Division property of equality.

7. Statement: x=-1. Reason: Symmetric property of equality.

Given the following systems of linear equations,

6x + 20y = -62 (Equation 1)

3x - 9y = -12 (Equation 2)

Step 1 : Solve 6x+20y=−62 for x:

6x + 20y + (−20y) = −62 + (−20y) (Add -20y to both sides)

6x = −20y −62

6x/6 = (−20y −62)/6 (Divide both sides by 6)

x = (-10y/3) + (-31/3)

Substitute to Equation 2:

3x−9y=−12

3[(-10y/3) + (-31/3)] - 9y = -12

−19y−31=−12 (Simplify both sides of the equation)

−19y−31+31=−12+31 (Add 31 to both sides)

−19y=19

-19y/-19 = 19/-19 (Divide both sides by -19)

y= −1

Step 2: Substitute −1 for y in x =(-10y/3) + (-31/3)

x =(-10(-1)/3) + (-31/3)

x = -7

Answer:

x=−7 and y=−1

EXPLANATION

The intercept-form of a quadratic function is as follows:

y = a(x - p)(x - q)

Now, as the roots are (-5,0)

Since the parabola passes through the point (−5,0), then 0=25a−5b+c

Since the parabola passes through the point (−1,0), then 0=a−b+c.

Since the parabola passes through the point (−7,−24), then −24=49a−7b+c.

Thus, we have obtained the following system:

Solving it we get that a=−2, b=−12, c=−10.

Thus, the equation of the parabola is y=(−2x−10)(x+1)

The graph of the given line is attached below.

We are given the line:-

y = (3/5)x - 4

We will find the x and y intercepts of the line to plot in the graph.

As the equation is already in the slope intercept form, we can write,

The y-intercept of the line is -4.

Hence, the coordinates of the point will be (0,-4).

To find the x - intercept of the line we will put y = 0 in the given line.

0 = (3/5)x - 4

4 = 3x/5

x = 20/3

The coordinates of the point will be (20/3,0).

We can plot these points to get the desired graph.
