▪︎Side 15 cm, 18 cm and x cm form a right angle triangle.

We know that :

[tex] =\tt {hypotenuse}^{2} = {leg}^{2} + {leg}^{2} [/tex]

Which means :

[tex] =\tt {15}^{2} + {x}^{2} = {18}^{2} [/tex]

[tex] =\tt 225 + {x}^{2} = 324[/tex]

[tex] =\tt {x}^{2} = 324 - 225[/tex]

[tex] = \tt {x}^{2} = 99[/tex]

[tex]\color{plum} =\tt x = 9.9 \: cm[/tex]

Thus, x (radius) = 9.9 cm

We know that :

[tex]\color{hotpink}\tt \: Surface \: area \: of \: cone \color{plum}=\pi r(r + \sqrt{ {h}^{2} + {r}^{2} } [/tex]

Then, the surface area of this cone :

[tex] = \tt3.14 \times 9.9 \times( 9.9 + \sqrt{ {15}^{2} + {9.9}^{2} } )[/tex]

[tex] =\tt 3.14 \times 9.9 \times( 9.9 + \sqrt{323.01} )[/tex]

[tex] =\tt 3.14 \times 9.9 \times (9.9 + 18)[/tex]

[tex] =\tt 3.14 \times 9.9 \times 27.9[/tex]

[tex] = \tt31.09 \times 27.9[/tex]

[tex]\color{plum} =\tt\bold{ 867.4 \: cm}[/tex]

Therefore, the surface area of this cone = 867.4 cm

Answer:

y=3.5x+4; A(_,5) B(10,_)

Step-by-step explanation:

.Find point A: Substitute y value given, solve for x:

.

5=3.5x+4

1=3.5x

1/3.5=x

0.2857=x

.

Point A=(0.2857,5)

.

Find point B: Substitute x value given, solve for y:

.

y=3.5(10)+4

y=35+4

y=39

.

Point B=(10,39)

.

Slope:

In slope intercept form y=mx+b, m=slope

.

Slope=m=3.5

.

The others are done the same way.

Answer:

86 cm²

Step-by-step explanation:

1) Calculate the area of the square

[tex]A=lw\\A=20*20\\A=400[/tex]

Therefore, the area of the square is 400 cm².

2) Calculate the area of the circle

[tex]A=\pi r^2\\[/tex]

[tex]\pi[/tex] we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.

[tex]A=3.14*10^2\\A=3.14*100\\A=314[/tex]

Therefore, the area of the circle is 314 cm².

3) Subtract the area of the circle from the area of the square

[tex]A=400-314\\A=86[/tex]

Therefore, the area of the shaded region is 86 cm².

I hope this helps!

Step-by-step explanation:

Given,

One side of the square = 20 cm

Therefore, Area of the square = side × side

= 20 cm × 20 cm

[tex] \: \: \: \: \: \: \: \: = 400 {cm}^{2} [/tex]

Also, known that

One side of the square = Diameter of the circle = 20 cm

So, radius of the circle = 20/2 cm = 10 cm

Therefore, area of the square

[tex] \: \: \: \: \: \ \: \: \: \: = \pi{r}^{2} [/tex]

[tex] = 3.14 \times {(10cm)}^{2} [/tex]

[tex] = 3.14 \times 100 {cm}^{2} [/tex]

[tex] = 314 {cm}^{2} [/tex]

Hence, area of the shaded region is

= Area of the square. - Area of the circle

[tex] = 400 {cm}^{2} - 314 {cm}^{2} [/tex]

[tex] = 86 {cm}^{2} (ans)[/tex]

Given:

The table of values.

To find:

The equation in slope intercept form.

Solution:

From the given table it is clear that the line passes through the points (5,17), (8,41) and (12,73).

Consider any two points from the table, i.e., (5,17) and (8,41). So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-17=\dfrac{41-17}{8-5}(x-5)[/tex]

[tex]y-17=\dfrac{24}{3}(x-5)[/tex]

[tex]y-17=8(x-5)[/tex]

[tex]y=8x-40+17[/tex]

[tex]y=8x-23[/tex]

Therefore, the equation of line in slope intercept form is [tex]y=8x-23[/tex].

2.8

Step-by-step explanation:

You need to keep these: 2.8

You will need to look at the second decimal: 2.844

Since it is under 5, you don’t need to increase 8 any further. If it was 5 or greater, you would have to change the 8 up to a 9.

Answer:

$ 4,500.00

Step-by-step explanation:

I = $ 4,500.00

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year,

then, solving our equation

I = 10000 × 0.09 × 5 = 4500

I = $ 4,500.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 9% per year

for 5 years is $ 4,500.00.
