Answer:

y = 54/25

Step-by-step explanation:

y = p×q^(x-1)

when x = 1 then y = 10

so,

10 = p×q^(1-1)

or, 10 = p×1

or, p = 10

when x = 6 then y = 0.7776

0.7776=p×q^(6-1)

or, 0.7776=p×q^5

or, 0.7776=10×q⁵

[0.7776 = 7776/10000 = 486/625]

or, 486/625 = 10×q⁵

or, 486/6250=q⁵

or, [tex] \frac{ \sqrt[5]{486} }{ \sqrt[5]{6250} } = q[/tex]

or, [tex]q = \frac{3 \sqrt[5]{2} }{5 \sqrt[5]{2} } [/tex]

or, q = 3/5

so, when x = 4

y = p×q^(x-1)

y = 10×(3/5)^(4-1)

y = 10×(3/5)^3

y = 10×27/125

y = 54/25

Answer:

  10%

Step-by-step explanation:

The balance when principal P is invested at rate r compounded n times per year for t years is ...

  A = P(1 +r/n)^(nt)

We have A = 847, P = 700, n = 1, t = 2 and we want to solve for r. Filling in the values and solving the equation gives ...

  847 = 700(1 +r)^2

  √(847/700) = 1 +r = 1.10 . . . . divide by 700 and take the square root

  r = 0.10 = 10% . . . . . subtract 1

An interest rate of 10% compounded annually will give a balance of ₹847.

  (b)  tangible approximation of the product that often look and feel like the product

Step-by-step explanation:

"Physical" means it exists as an object in the real world, not just as a model on a computer screen. "Prototype" means it is an approximation of the finished product, lacking in one or more details of appearance, structure, or functionality.

Answer:

the other guy is wrong the answer is 1.27945 × 10 but then 10 is to the power of 4 but I do not know how to type that.

Step-by-step explanation:

To convert 12794.5 into scientific notation, follow these steps:

1.       Move the decimal 4 times to left in the number so that the resulting number, m = 1.27945, is greater than or equal to 1 but less than 10

2.      Since we moved the decimal to the left the exponent n is positive

n = 4

3. Write in the scientific notation form, m × 10 to the power of n

= 1.27945 × 10 to the power of 4

Therefore, the decimal number 12794.5 written in scientific notation is 1.27945 × 10to the power of 4 and it has 6 significant figures.

Answer:

  9 ft

Step-by-step explanation:

The length is 3 times the width, so in the larger rectangle it will be ...

  length = 3×width = 3×(3 ft) = 9 ft

The length of the larger rectangle is 9 feet.

_____

Additional comment

We used the fact that the ratios of side lengths (length:width) are the same for similar figures.

You can also recognize that the larger rectangle's dimensions are 3/2 times those of the smaller rectangle. (3/2)(6 ft) = 9 ft . . . length of larger rectangle

Answer:

The answer is 9

I might be wrong....

Step-by-step explanation:

I got it because 2x3=6 so i multiplied 3x3 and 9

Answer: The car is traveling at 73.63638 Mph

Step-by-step explanation:

1 yard per second is the same as 3 feet per second.

there are 5280ft per mile

So, at 36 yards per second, the car is traveling at 108/5280th (0.02045455) of a mile per second

0.02045455 * 60 (seconds) * 60 (minutes) = 73.63638 Mph

Answer:

z = 110

Step-by-step explanation:

The measure of an angle created by the intersection of two secants outside a circle is half the difference of the angles it intercepts. In this it would be:

2x + 15 = 1/2 * (10x + 20 - 80)

We can now solve:

4x + 30 = 10x - 60

30 = 6x - 60

6x = 90

x = 15

This means the values of 10x + 20 is 10(15) + 20, which is 170.

Now, we can add up all the arcs in a circle, which sum to 360 degrees:

360 = z + 170 + 80

360 = z + 250

z = 110

Answer:

[tex]A)\ \ z = 110[/tex]

Step-by-step explanation:

One is given a circle with two secants. Please note that a secant is a line that intersects a circle in two places. The secant exterior angle theorem states that when two secants intersect each other outside of a circle, the measure of the angle formed is half the of the positive difference of the intersecting arcs. One can apply this theorem here by stating the following:

[tex]2x+15=\frac{(10x+20)-(80)}{2}[/tex]

Simplify,

[tex]2x+15=\frac{(10x+20)-(80)}{2}[/tex]

[tex]2x+15=\frac{10x-60}{2}[/tex]

[tex]2x+15=5x-30[/tex]

Inverse operations,

[tex]2x+15=5x-30[/tex]

[tex]15=3x-30[/tex]

[tex]45=3x[/tex]

[tex]15=x[/tex]

Substitute this value into the equation for one of the intersecting arcs to find the numerical value of that intersecting arc:

[tex]10x+20\\x = 15\\\\10(15) + 20\\= 150 + 20\\= 170[/tex]

The sum of all arc measures in a circle is (360) degrees. One can apply this here by stating the following:

[tex]80 + 170 + z = 360[/tex]

Simplify,

[tex]80 + 170 + z = 360[/tex]

[tex]250 + z = 360[/tex]

Inverse operations,

[tex]250 + z = 360[/tex]

[tex]z = 110[/tex]
