Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous yea

Varvara68 [4.7K]

Answer: $56,900\left( 0.919\right)^x$

Step-by-step explanation:

Given

Marcos purchased a sailboat for $\$56,900$

Each year the boat will decrease in value by $8.1\%$

After 1 year it is

$\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\$

after another year it becomes

$\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2$

After $x$ years it is

$\Rightarrow 56,900\left( 1-0.081\right)^x$

$\Rightarrow 56,900\left( 0.919\right)^x$

1. Use the image of the circle to identify the length of the radius, diameter, and circumference. Leave all answers in terms of

Grace [21]

Answer:

Radius = r = 7.5

Diameter = d = 15

Circumference = C = 15π

Step-by-step explanation:

We are given the image of a circle with a straight line passing through the center of the circle and touching its edges. Such a line is known as the diameter of the circle. From the image we can see the length of the diameter of the circle is d = 15 units.

Radius is define as half of the diameter. Since the diameter is 15 units, the radius of the given circle will be half of 15 which is r = 7.5 units.

Circumference of the circle = C = 2πr

Using the value of radius(r), we can write the circumference as:

C = 2π(7.5) = 15π

Pls pls answer this asap no wrong answers pls

klemol [59]

Answer:

20, increased, Bianca

Step-by-step explanation:

First one:

He is shown to have travelled 20km in 1 hour, so that's 20km/h.

Second:

The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.

Third:

Bianca's line hits 50km before Alberto, so therefore she finished first.

Let me know if this makes sense, hope it helped! :D

Help pls pls pls pls

adelina 88 [10]

Answer:

m∠1= 41°

m∠2= 85°

m∠3= 95°

m∠4= 85°

m∠5= 36°

m∠6= 49°

m∠7= 106°

Step-by-step explanation:

To find m∠2

95+m∠2= 180

-95 - 95

m∠2= 85

To find m∠4

Since they are vertical angles, m∠2=m∠4, that means that they are both 85°

To find m∠1

There is four angles in this shape, so the sum is 360 degrees.

90+144+85+m∠1= 360

319+m∠1= 360

-319 -319

m∠1= 41°

To find m∠5

144+m∠5= 180

-144 -144

m∠5= 36°

To find m∠6

m∠5+m∠3+m∠6= 180

36+95+m∠6= 180

131+m∠6= 180

-131 -131

m∠= 49°

To find m∠7

You need to find the sum of the other unidentified angle.

m∠6+m∠=180

49+m∠= 180

-49 -49

m∠= 131

Now you need to find the sum of all the angles in the quadrilateral to get the measure for angle 7.

131+38+85+m∠7= 360

254+m∠7= 360

-254 -254

m∠= 106°

a napkin has an area of 5 square inch . what is the side length of the napkin to the nearest hundredth of an inch?

mart [117]

The side length is 2.24 inches.

The area of a square is given by s²; we have
s² = 5

To find the value of s, we take the square root of each side:
√s² = √5
s = √5 = 2.236 ≈ 2.24
