Step-by-step explanation:

Go down on the graph 8 for the Y-axis then go across 4 on the X-axis.

Answer:

See solutions below

Step-by-step explanation:

For what values of X are the statements below true

A. 1x>x+1

x >x+1

x-x>1

0x > 1

x > 1/0

X >∞

B) |1-x|>3

The fucntion can both be positive and negative

For the negative function

-(1-x) > 3

-1+x > 3

x > 3+1

x > 4

For the positive function

1-x > 3

-x > 3 - 1

-x > 2

x < -2

Hence the required solutions are x > 4 and x < -2

c) For the equation

|x-15| < 0

-(x - 15) < 0

-x + 15 < 0

-x < -15

x > 15

Also x-15 < 0

x < 0+15

x < 15

Hence the required solution is x > 15 and x < 15

Answer:

Movie: $4.25

Video Game: $5.25

Step-by-step explanation:

For this problem, we can use system of equations to solve for the rental costs of the movies and video games. Let's use x for movies and y for video games.

Equation 1

5x+3y=37

Equation 2

2x+6y=40

To start, we can use elimination to solve for x and y. Let's cancel out y. To do so, we have to multiply the first equation by 2 to get the y equal.

10x+6y=74

Now that the y are equal, we can subtract both equations.

8x=34

x=4.25

The movie rental cost is $4.25.

Now that we know x, we can plug in to find y.

2(4.25)+6y=40

8.5+6y=40

6y=31.5

y=5.25

The rental cost for video games is $5.25.

The vertex is (1, -4)

Step-by-step explanation:

The principal if the bank manager also wants to advertise that one can earn $10 the first month is $4000.

From the information, the simple interest is $10 and the rate is illustrated as 3%.

The formula for the simple interest in a month is illustrated as:

S = (p × r × t/12 / 100)

r = rate

t = time

S = interest

Place the values in the formula:

10 = p × 3 × 1 / 100 × 12

10 = 3p/1200

Cross multiply

3p = 12000

Divide

p = 12000/3

p = 4000

The principal is $4000.

Answer:

0.188

Step-by-step explanation:

47/250 = 0.188

Answer:

hmax = 628 ft

Step-by-step explanation:

The bullet will reach its maximum height when its velocity h'(t) becomes zero. The equation of motion is

h(t) = -16t^2 + 200t + 3

Taking the derivative of h(t) is

h'(t) = -32t + 200

Solving for t when h'(t) = 0, we get

t = 200/32 = 6.25 s

and this is the time it takes for the bullet to reach its maximum height. Using this value for t into h(t), we get

h = -16(6.25 s)^2 + 200(6.25 s) + 3

= 628 ft

Answer:

8 hours and 26 minutes

Step-by-step explanation:

To convert 506 minutes to hours and minutes, we can use the fact that there are 60 minutes in one hour.

First, we can divide 506 by 60 to find the number of hours:

506 ÷ 60 = 8 with a remainder of 26

This means that 506 minutes is equal to 8 hours and 26 minutes.

Therefore, the conversion of 506 minutes to hours and minutes is:

8 hours and 26 minutes

Answer:

\(Perimeter = 38.6\)

Step-by-step explanation:

Given

\(A\ B = 13\)

\(B\ F = 9\)

\(F\ C = 5.6\)

Required

Calculate the perimeter of A B C

To calculate the perimeter of A B C, we sum up the sides of the triangle

i.e.

\(Perimeter = A B + B\ C + A\ C\)

AB is given in the question already.

So, we need to calculate B F and F C

To solve for BF, we consider triangle B F C

Using Pythagoras Theorem, we have:

\(B\ C^2 = B\ F^2 + F\ C^2\)

Substitute values for BF and FC;

\(B\ C^2 = 9^2 + 5.6^2\)

\(B\ C^2 = 81 + 31.36\)

\(B\ C^2 = 112.36\)

\(B\ C^2= \sqrt{112.36\)

\(B\ C = 10.6\)

Next, we calculate A C.

To calculate A C, we need to calculate A F, considering triangle B F A

Using Pythagoras Theorem, we have:

\(A\ B^2 = B\ F^2 + A\ F^2\)

Substitute values for B F and A B;

\(13^2 = 9^2 + A\ F^2\)

\(169= 81 + A\ F^2\)

\(A\ F^2 = 169 - 81\)

\(A\ F^2 = 88\)

\(A\ F = \sqrt{88\)

\(A\ F = 9.4\)

Since F lies on line A C:

\(A\ C = A\ F + F\ C\)

\(A\ C = 9.4 + 5.6\)

\(A\ C = 15.0\)

Recall that:

\(Perimeter = A\ B + B\ C + A\ C\)

\(Perimeter = 13 + 10.6 + 15.0\)

\(Perimeter = 38.6\)

Hence, the perimeter is 38.6

Given that P is the orthocenter of triangle ABC, applying the properties of an orthocenter of a triangle and the Pythagorean Theorem, each measure and the perimeter of △ABC are:

Recall:

Given that P is the orthocenter of triangle ABC, where,

Perimeter of △ABC = AB + BC + AC

First, we need to find BC and AC.

△BFC is a right triangle, apply Pythagorean theorem to find BC:

\(BC = \sqrt{BF^2 + FC^2}\)

\(BC = \sqrt{9^2 + 5.6^2}\\\\\mathbf{BC = 10.6}\)

△BFA is a right triangle, apply Pythagorean theorem to find FA:

\(FA = \sqrt{AB^2 - BF^2}\)

\(FA = \sqrt{13^2 - 9^2}\\\\\mathbf{FA = 9.4}\)

AC = FA + FC

AC = 9.4 + 5.6

AC = 15

Perimeter of △ABC = AB + BC + AC

Perimeter of △ABC = 13 + 10.6 + 15

Perimeter of △ABC = 38.6 units

Therefore, given that P is the orthocenter of triangle ABC, applying the properties of an orthocenter of a triangle and the Pythagorean Theorem, each measure and the perimeter of △ABC are:

Answer:

\(0 \leq p < 6\)

Step-by-step explanation:

Given

\(t = 6.95p + 29.95\)

\(Amount = 70\)

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in \(t = 6.95p + 29.95\)

\(70 = 6.95p + 29.95\)

Collect Like Terms

\(6.95p = 70 - 29.95\)

\(6.95p = 40.05\)

Solve for p

\(p = 40.05/6.95\)

Step-by-step explanation:

HE= 1/3(HG)

x-3=1/3(4x-15)

3x-9=4x-15

-x=-24

x=24

Answer:

HE=3

Step-by-step explanation:

Equations

With the data provided, we can set up an equation. Then we need to solve the equation. Finally, we use the just-found value of x to calculate HE.

Data:

HE=1/3 HG

HE=x-3

HG=4x-15

Replacing the last two equations in the first:

x-3=1/3(4x-15)

Multiply both sides by 3:

3(x-3)=4x-15

Operate:

3x-9=4x-15

Moving x's to the left and numbers to the right:

3x-4x=-15+9

Joining like terms:

-x=-6

Multiply by -1:

x=6

Since HE= x-3:

HE=6-3

HE=3

Rounded to the nearest hundredth, the value of y at \(x = 7\) is approximately \(12.78\), according to the concept of linear regression line.

To find the linear regression line for the given data, we can use statistical software or a calculator. The equation of the linear regression line is of the form \(y = mx + b\), where m represents the slope and b represents the y-intercept.

Using the provided data, the linear regression line equation is:

\(\[ y = 1.3642x + 3.2324 \]\)

To find the value of \(y\) at \(x = 7\), we substitute \(x = 7\) into the equation:

\(\[ y = 1.3642(7) + 3.2324 \]\)

Simplifying the equation, we get:

\(\[ y = 9.5494 + 3.2324 \]\[ y = 12.7818 \]\)

In conclusion, the linear regression analysis allows us to determine the relationship between the variables x and y in the given data set. By finding the equation of the linear regression line, we can estimate the value of y for any given x. In this case, the linear regression line equation is \(y = 1.3642x + 3.2324\). By substituting \(x = 7\) into the equation, we find that the estimated value of y is approximately \(12.78\). This analysis provides a useful tool for predicting and understanding the relationship between variables, allowing us to make informed decisions and interpretations based on the data.

2303

Step-by-step explanation:

Let the smaller of the two odd integers be x.

Then the next odd integer is x + 2.

Since the sum of these 2 integers is 96, we may write x + (x + 2) = 96

Now solving for x we obtain:

2x = 94

x = 47

To find the next value we can subtract 47 from 96, which is 49.

Hence, the required two integers are 47 and 49. Multiplying them, we get a product of 2303.
