Answer: (1.-3), (-1,-5)

Step-by-step explanation:

Substituting the x coordinates into the equation, we get that the result is equal to the y coordinate of the points.

Thus, the points lie on the line.

The arguments are valid therefore F  F →T

A truth table is a mathematical table which shows the truth values for a given set of arguments and tells if the argument is valid or invalid.

Analysis:

Argument 1( P)= if a person is on this reality show(true) T

Argument 2(Q) = the person is self absorbed true(T)

Laura is not self absorbed = False(≈Q)

Laura wont be on the reality show = False(≈P)

So she can only be on the reality show if she is self absorbed else she cannot.

so F F → T

Which means that the argument is valid.

Answer:

The length of the shortest side of the pentagon would be:

40.2

Answer:

n = 4

Step-by-step explanation:

[tex]\frac{n}{6} =\frac{24}{36}[/tex]

cross multiply

24*6 = 144

n * 36 = 36n

144 = 36n

divide both sides by 36

n = 4

answer is D

n=4

simplify the fraction on the right to get 4/6

n/6 = 4/6

since denominators are same, you can cancel those

therefore, your answer will be n=4

Tommy and his father will meet after 2400 seconds or 40 minutes. So they will meet at 3:40 pm.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that:-

The time will be calculated by using the relative speed concept.

Relative speed = Speed of father - Speed of Tommy

Relative speed = 1.65 - 1.35

Relative speed = 0.3 meter per second

Relative speed = Distance / Time

0.3 = 720 / Time

Time = 720 / 0.3

Time = 2400 seconds = 2400/ 60 = 40 minutes

We know that both departed at 3 pm they will meet at 3:40 pm.

Therefore Tommy and his father will meet after 2400 seconds or 40 minutes. So they will meet at 3:40 pm.

Answer:

They will meet at 3:04 p.m

Step-by-step explanation:

Since they are walking toward each other, that means we should add their speed together:

speed = 1.35 m/s + 1.65 m/s

          = 3 m/s

Now that we have found the speed, we can calculate the time:

time = 720 meters / 3 m/s

      = 240 seconds

      = 4 minutes ( 240 seconds is 4 minutes)

The length of the unknown leg of the triangle is 15 m.

Length of one leg = 20 m

Length of the hypotenuse= 25m

As it is a right angled triangle we can use pythogoras theorem.

(20) (20)  + y(y) = (25) (25)

400 + y(y) = 625

[tex]y^{2}[/tex]= 225

Step-by-step explanation:

in such a case the easiest approach might be using the point-slope form of a line equation :

y - y1 = m(x - x1)

with m being the slope, and (x1, y1) being a point on the line.

so, in our case that would be

y - 8 = 8(x - 4)

simplified this would be

y - 8 = 8x - 32

y = 8x - 24

FYI - this would be then the slope-intercept form (-24 would be the intercept point on the y-axis).

Answer:

AB = 11 units

Step-by-step explanation:

a given ratio also tells us how many equally sized units there are in the whole (in this case the line).

the ratio 4:7 tells us therefore, that from the whole line 7 ratii units (of 7+4 = 11 ratio units) are on the side of CB.

4 ratio units (of the 11 ratio units) are on the side of AC.

AC is the distance between A and C.

that is

0.6 - -3.4 = 0.6 + 3.4 = 4 line units

aha ! the distance is 4 units on the number line, and the ratio tells us that AC is 4 ratio units.

so, line unit and ratio units are 1:1 the same.

that means that CB with 7 ratio units is then also 7 line units long.

so, the whole line AB is then 4 + 7 = 11 line units long.

Answer:

v240

Step-by-step explanation:

The equation of the quadratic function shown in the graph y - 8 = -2(x + 1)².

The vertex of this parabola is (-1, 8).  It opens downward, so the x² term has a negative coefficient.  The zeros are (-3, 0) and (1, 0), and the y-intercept is (0, 7).

Through the vertex form of the equation of a parabola we get:

y - (8) = a(x - (-1)) + 7, or.y - 8 = a(x + 1)².

Find coefficient a by substituting the coordinates (-3, 0) in this equation:

0 - 8 = a(-3 + 1)^2, or

-8 = a(-2)² or a = -2

The desired equation is y - 8 = -2(x + 1)^2

Answer: All real numbers

Step-by-step explanation:

I assume you meant [tex]y=5.3^x[/tex].

In this case, the domain is the set of real numbers, as is with most standard exponential functions.

Answer:

-28

Step-by-step explanation:

Find 5y-3 , given -3y - 8 = 7.

First, we will multiply -3y - 8 = 7 by [tex]-\frac{5}{3}[/tex] to get 5y first.

[tex]-\frac{5}{3} (-3y-8)=-\frac{5}{3} (7)\\5y+\frac{40}{3} =-\frac{35}{3} \\[/tex]

Now we will get the constant on the left side of the equation to 3.

[tex]5y+\frac{40}{3} -\frac{40}{3} =-\frac{35}{3} -\frac{40}{3} \\5y=-25\\5y-3=-25-3\\5y-3=-28[/tex]

The solution to the system of equations is: (1, -8).

The solution is the coordinate of the point where both lines of the equations meet.

Second equation: 3y + 30 = 6x, rewrote in slope-intercept form:

3y = 6x - 30

y = 6x/3 - 30/3

y = 2x - 10 --> eqn. 1

Find the slope (m) and y-intercept (b) of the first graphed equation:

Slope (m) = change in y/change in x = rise/run = -4/2 = -2

The line intersects the y-axis at y = -6, so, the y-intercept, b = -6.

The first equation would be: y = -2x - 6 ---> eqn. 2

Subtract eqn. 2 from eqn. 1 to eliminate x

y = 2x - 10 --> eqn. 1

y = -2x - 6 ---> eqn. 2

2y = 0 - 16

2y = -16

y = -16/2

y = -8

Substitute y = -8 into eqn. 1 to find x:

-8 = 2x - 10

-8 + 10 = 2x

2 = 2x

2/2 = x

1 = x

x = 1

The solution is therefore: (1, -8).

Step-by-step explanation:

Compound interest is generally written as: [tex]A=P(1+\frac{r}{n})^{nt}[/tex] where P = principle amount, r = interest rate, n=compound periods, t = time. This is compounded continuously which can be defined as: [tex]A=Pe^{rt}[/tex]. If you're confused what e is, one of the definitions, is [tex]\lim_{x\to\infty}{(1+\frac{1}{x})^x[/tex]. This is essentially the very definition of continuous compound. It's when the amount of compounds (n in the equation) goes towards infinity. So using the previous defined equation simply plug the values into the equation.

[tex]A=(40000)e^{0.025*8}[/tex]

Multiply inside the exponent

[tex]A=(40000)*e^{0.2}[/tex]
