x = 91

Answer:

Decay

Step-by-step explanation:

The value, y of an investment x is given by:

y = 25000(1.16)^-x

x = number of month after investment

y = value of investment after x months

The function f(y) above is an exponential usually related in the form:

y = Ar^-x

Plugging values of x into the function :

After 1 month; x = 1

y = 25000(1.16)^-1 = 21551.724

After 2 month; x = 2

y = 25000(1.16)^-2 = 18579.072

After 3 month; x = 3

y = 25000(1.16)^-3 = 16016.441

Since y is decreasing with increasing value of x, then we have a decay

Answer:

x = 12

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 81 = 15²

x² + 81 = 225 ( subtract 81 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12

Answer:

0 mn

Step-by-step explanation:

First you would write the equation 2+(-4)+8+(-6)

Now let’s solve starting from the left.

2+(-4) = -2

This is the equation so far: -2+8+(-6)

Then you would solve the right side 8+(-6) = 2

Now we have -2 + 2 which equals 0.

PS. You can also do in another way like 2-4+8-6. It’s the same method and concept.

Answer:

8). TN = 22 units ; 9). √165

Step-by-step explanation:

The circumcenter of a triangle is the point in the plane equidistant from the three vertices of the triangle.

8). 6x - 56 = 3x - 17

3x = 39

x = 13

TN = 22 units

9). 4x - 17 = x + 10

3x = 27

x = 9

TN = 19

RT = [tex]\sqrt{TN^2 - RN^2}[/tex]

RT = [tex]\sqrt{361-196}[/tex] = √165 ≈ 12.8 units

Applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:

8. TN = 22

9. RT = 12.8

Recall:

8. Find TN

Given,

Thus,

6x - 56 = 3x - 17 (MT = TN = TP, because they are equidistant from the circumcenter, T.)

6x - 3x = 56 - 17

3x = 39

x = 13

TN = TP = 3x - 17

TN = 3x - 17

TN = 3(13) - 17

TN = 22

9. Find RT

Given,

Thus,

4x - 17 = x + 10 (TN = TP)

4x - x = 17 + 10

3x = 27

x = 9

TN = 4x - 17

TN = 4(9) - 17

TN = 19

To find RT, apply the Pythagorean Theorem

[tex]RT = \sqrt{TN^2 - RN^2}[/tex]

[tex]RT = \sqrt{19^2 - 14^2}\\\\\mathbf{RT = 12.8}[/tex]

In summary, applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:

8. TN = 22

9. RT = 12.8

Answer: (-3,3)

Step-by-step explanation:Answer: (-3,3)

Step-by-step explanation: P= IRT solve for T To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side. IRT means that I and R are multiplied by T. To get rid of them we must do the opposite of multiply, which is divide. But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side. So if we divide the right side by IR, we must also divide the left side by IR

Answer:

We conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

Step-by-step explanation:

Given the line

y+2x=4

converting into the slope-intercept form y = mx+b where m is the slope

y = -2x+4

comparing with the slope-intercept form

Thus, the slope is: m = -2

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -2

The slope of the new line perpendicular to the given line = – 1/m

                                                                                                = -1/-2 = 1/2

Using the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 1/2 and the point (-3, 5)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=\frac{1}{2}\left(x-\left(-3\right)\right)[/tex]

[tex]y-5=\frac{1}{2}\left(x+3\right)[/tex]

Add 5 to both sides

[tex]y-5+5=\frac{1}{2}\left(x+3\right)+5[/tex]

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

Therefore, we conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:

[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

Answer:

-6

Step-by-step explanation:

3(-4) = -12

-2(-3)= 6

-12+6= -6

Answer:

-6

Step-by-step explanation:

If x = -4 and y = -3, the equation should be set up like this: 3(-4) - 2(-3). The rule is if you multiply a 1 positive number by 1 negative number, the answer will be negative.

3(-4) = -12

2(-3) = -6

Then, once you figure out the multiplication, finish up the equation by subtracting.

-12 - (-6) = -6

Answer: y = 4km + 2km*x

Step-by-step explanation:

We know that Madelyn already cycled 4km this year, so we start at that point.

Now, each time that she goes to work, she cycles 2 km in total.

Now, if she does x trips to work, then she cycles 2km x times, this means that in total she would cycle 2km*x

if we also count the 4km she already has, we have the linear equation:

y = 4km + 2km*x

This is the equation we wanted to get.

I think it is the first one you can solve the system using either substitution, elimination, or graphing and the get the same answer.

Step-by-step explanation:

Given:

For cylinder P: radius = 4.25 in. and height = 14 in.

For cylinder Q: radius = 7 in. and height = 8.5 in.

To find:

The volume of each cylinder.

Solution:

Volume of a cylinder is

[tex]V=\pi r^2h[/tex]

where, r is radius and h is height. Use 3.14 for [tex]\pi[/tex].

Using the above formula, the volume of cylinder P is

[tex]V_P=(3.14)(4.25)^2(14)[/tex]

[tex]V_P=794.0275[/tex]

[tex]V_P\approx 794.03[/tex]

Using the above formula, the volume of cylinder Q is

[tex]V_Q=(3.14)(7)^2(8.5)[/tex]

[tex]V_Q=1307.81[/tex]

Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.

The volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.

Suppose that the radius of the considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

The given information is

For cylinder P:

radius = 4.25 in. and height = 14 in.

For cylinder Q:

radius = 7 in. and height = 8.5 in.

To find the volume of each cylinder.

The volume of a cylinder

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

where r is radius and h is height.

Using the above formula,

the volume of cylinder P

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

[tex]V = 3.14 \times (4.25)^2 \times 14 \: \rm unit^3\\\\V = 794.03[/tex]

The volume of cylinder Q

[tex]V = \pi r^2 h \: \rm unit^3\\\\V = 3.14 \times 7^2 \times 8.5 \: \rm unit^3\\\\V =1307.81[/tex]

Therefore, the volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.
