The triangle in which the side are nine inches long has a perimeter of 27 inches.

The perimeter of a triangle is the sum of the length of the whole side.

The triangle have three sides and the perimeter is the sum of the whole sides.

According to the question, the triangle has the whole sides as 9 inches.

This means the triangle is an equilateral triangle.

Therefore,

length of side = 9 inches

perimeter = 9 + 9 + 9

perimeter = 27 inches

Foci [tex](0,\pm\frac{\sqrt{17}}{4})[/tex]

Vertices:[tex](0,\pm 1)[/tex]

Eccentricity, e=[tex]\frac{\sqrt{17}}{4}[/tex]

Length of latus rectum=[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

We are given that

[tex]y^2-16x^2=1[/tex]

[tex]y^2-\frac{x^2}{(\frac{1}{4})^2}=1[/tex]

The equation of hyperbola is along y-axis because y is positive

Compare the equation with

[tex]y^2/a^2-x^2/b^2=1[/tex] (Along y-axis)

We get

a=1, b=1/4

[tex]a^2+b^2=c^2[/tex]

[tex]1+\frac{1}{16}=c^2[/tex]

[tex]\frac{16+1}{16}=c^2[/tex]

[tex]c^2=\frac{17}{16}[/tex]

[tex]c=\pm \frac{\sqrt{17}}{4}[/tex]

Therefore,

The coordinates of foci=[tex](0,\pm c)=(0,\pm\frac{\sqrt{17}}{4})[/tex]

The coordinated of vertices=[tex](0,\pm a)=(0,\pm 1)[/tex]

Eccentricity, e=c/a

[tex]e=\frac{\frac{\sqrt{17}}{4}}{1}=\frac{\sqrt{17}}{4}[/tex]

Length of latus rectum=[tex]\frac{2b^2}{a}[/tex]

Length of latus rectum=[tex]2\times \frac{1}{16}=\frac{1}{8}[/tex]

Step-by-step explanation:

Points ( -3,5 )( 6,-4 )

You use the slope formula to find the slope.

M = Y2 - Y1 over

      X2 - X1

Which is -4 - 5

               6 - -3 =         -9/9 = -1

The slope is -1

Now to find the y-intercept we use one of the x,y points ( I'll use 6,-4 )

And plug them in

-4 = -1(6) + b

-4 = -6 + b

+6   +6

2 = b

The equation will be y = -1x + 2

Answer:

[tex]v = 400000(2^\wedge d)[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Value = \$400000[/tex]

[tex]Rate = doubles[/tex] per decade

Required

Determine the equation of the function

The information given shows that the function is exponential and will be calculated using:

[tex]v = ab^d[/tex]

Where:

a = Initial Value = 400000

b = rate = 2

d = number of decades

v = the current value of the home

So, we have:

[tex]v = 400000* 2^\wedge d[/tex]

[tex]v = 400000(2^\wedge d)[/tex]

The equation that represents the value of the home is v = $400,00(2^d).

The home is appreciating in value. This means that the price of the house is increasing with the passage of time.

The formula that can be used to represent the appreciation is:

FV = P (1 + r)^n

v = $400,000(2^d)

Step-by-step explanation:

Sasha needs to collect 120 more cans to reach her goal.

let us say the total goal is 100x

it is given that

when she collected 180 cans she knew she had reached 60% of her goal.

it is made up of two words 'per' and 'cent' means it is the value out of a hundred.

60% of 100x= 60x

60x = 180(given)

x=3

total goal = 100x= 100*3=300

total goal left= 300-180=120

therefore, Sasha needs to collect 120 more cans to reach her goal.

Answer:

350 kilómetros por hora son 97,2222 metros por segundo ;)

The result of converting 350 km/h to meter per second is 97.22 m/s.

To convert from kilometers per hour (km/h) to meters per second (m/s), you need to apply the conversion factor.

The conversion factor for this conversion is 1 km/h = 0.2778 m/s.

To convert 350 km/h to m/s, multiply 350 by the conversion factor:

350 km/h×0.2778 m/s

= 97.22 m/s

Therefore, the result of converting 350 km/h to m/s is approximately 97.22 m/s.

As input 20 relates to two different outputs 40 and 50 the relation is not a function.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

We know a relation is a function if it is one to one implies every input relates to different output or many one as different inputs lead to the same output.

The given information is represented by a diagram has one-to-many relations as the input 20 leads to the same output 50 so this is a one-to-many relation and not a function.

Answer:

2x-3y=15

Step-by-step explanation:

y=2/3x-5

2/3x-y=5

3(2/3x-y)=3(5)

2x-3y=15

The required equation of the line is represented by 2x-  3y = 15 in standard form.

A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.

For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.

The equation is given in the question

⇒ y = 2/3x - 5

We have to determine the standard form of the given linear equation

⇒ y = 2/3x - 5

⇒2/3x - y = 5

Multiply by 3 into both sides of the above equation,

⇒3(2/3x-y) = 3(5)

⇒2x - 3y = 15

Therefore, the required equation of the line is represented by 2x-  3y = 15 in standard form.

Answer:

3780 bolts will be made by 8pm

Step-by-step explanation:

One Hour : 500 nuts or 840 bolts

Divide by 2

30 minutes : 250 nuts or 420 bolts

750 nuts : 500 + 250 = 750

so the machine took 1 hour and 30minutes

14:00 it started (2pm)

15:30 it switched to bolts

20:00 (8pm)

4 hours and 30minutes to get to 8pm

840 × 4 = 3360 bolts + 420 bolts = 3780 bolts was made
