Step-by-step explanation:

Answer:

128

Step-by-step explanation:

Let's start by figuring out the last side of the triangle

we can use the pathagoryous theroem and get

11.9²+x²=16.9²

Solve this and get x=12

Let's now compute the area of the triangle

b*h*.5

12*11.9*.5=71.4

So 71.4 is the area of the triangle

we now need to find the area of the semi circle.

to do this we are going to find the area and then divide it by 2

We know that the length is equal to 12 which means that the radius is 6

so we have

π6²/2

which is 56.55

We add the 71.4+56.55= 127.94 which rounds to 128

Answer:

212.758

Step-by-step explanation:

Find the semi-circle first, the diameter is 16.9 ft.

To find area:

Formula:

pi x radius x radius x 1/2

16.9 ÷ 2 = 8.45 (radius)

22/7 x 8.45 x 8.45 = 224.407 (Circle)

224.407 ÷ 2 = 112.203 (Semi circle)

Find the triangle:

1/2 x base x height or length x base x height

But for now, we will use the first one.

1/2 x 16.9 x 11.9 = 100.555

Now add them up.

100.555 + 112.203 = 212.758

Distance between y's (Δy)

d = √(Δy2 + Δx2) = √(12 + 02) = √1 = 1

Answer:

(7, -4)

Step-by-step explanation:

The formula for calculating midpoint is expressed as;

M(X, Y) = (x2+x1)/2, (y1+y2)/2

X = x1+x2/2

Y = y1+y2/2

Given

X = 5, Y = 1, x1 = 3, y1 = 6

Get x2

X = x1+x2/2

5 = 3+x2/2

10 = 3+x2

x2 = 10-3

x2 = 7

Get y2;

Y = y1+y2/2

1 = 6+y2/2

2 = 6+y2

y2 = 2-6

y2 = -4

Hence the coordinate of B is at (7, -4)

Answer:17

Step-by-step explanation:

trust me its right, no cap

As per compound interest,  it would take 17 years for the value of the account to reach $2,550

If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 -  [tex]e^{rn}[/tex]]

Given, the invested amount (P) = $790.

Rate of interest (r) = 6.9% = 0.069.

Let, the amount is invested for 'n' years.

The value of the amount after 'n' years = $2550.

Now, as per compound interest:

A = P. [tex]e^{rn}[/tex]

⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]

⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)

⇒ [tex]e^{(0.069n)}[/tex] = 3.23

⇒ 0.069n = 1.172

⇒ n = 17

Answer:

yes, no, no, yes

Step-by-step explanation:

Plug in each point into both equations to see which ones fit.

For the first point, (4,1) it works for both equations.

1=-2( 4 ) + 9, 1= -8 + 9, 1=1

4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18

Do it for the rest of the points and plug them in and you get,

no for (5,-3) because -1 does not equal to -3

no for (6,0) because -3 does not equal to 0

(-5,19) is yes because 19=19 and 18=18

Answer:

c

Step-by-step explanation:

The line segment OD is congruent to line segment OB. Therefore, option C is the correct answer.

Equal chords of a circle are equidistant from the center of the circle.

From the given figure, AC=EF=9.07.

So, AC and EF are equal chords.

Since, the chords are equal, they are equidistance from center.

Then, OD=OB

Therefore, option C is the correct answer.

Answer:

She would leave a tip of 2.0925 ($2.09)

Step-by-step explanation:

Replace x with any number and solve for Y.

Do this at least twice to get 2 points.

Place these points on the graph and draw a line through them.

See attached graph.

Let x = 2

y = 1.4(2)

y = 2.8

First point = (2,2.8)

Let x = 5

y = 1.4(5)

y = 7

Second point = (5,7)

The y-intercept is zero, that means the line is passing through origin.

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

The equation is given below.

y = 1.4x

In the above equation, y-intercept is not there, which means the line is passing through origin.

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Step-by-step explanation:

So first let's write a graph in vertex form with a vertex of (-5, -1)

We get

a(x+5)²-1

We now need to determine a

we know that when x= -2 y=2 which means we have

a(-2+5)²-1=2

Solve for a

a(3)²=3

9a=3

a=3/9

a=1/3

Now that we know what a is equal to we can write our equation
