In the below figure angle abc is 69 degree, angle acb is 31 degree so find the angle bdc

Answer:

a) It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are: A(-2, -1)

b) We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

c) The coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]        

Step-by-step explanation:

Part a)

Important Tip:

It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are:

Part b)

We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

Part c)

We can determine the coordinates of the midpoint of AB using the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

In our case, we have:

A(x₁, y₁) = A(-2, -1)

B(x₂, y₂) = B (-2, 4)

so substituting [tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:4\right)[/tex] in the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

            [tex]=\left(\frac{-2-2}{2},\:\frac{4-2}{2}\right)[/tex]

Refine

            [tex]=\left(-2,\:\frac{3}{2}\right)[/tex]

Therefore, the coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]

Answer:

Step-by-step explanation:

f(x) = -9x + 8

f(-2)

______________

When we have a function f(x), x can be plugged in with anything, when plugged, the equation the function f(x) is tied too will also have x replaced with the value.

Therefore, if f(x) equals f(-2), -9(-2) + 8

Multiply :

-9(-2) + 8

18 + 8

Answer:

The correct option is a.

Step-by-step explanation:

It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.

EMI on $1000 is $8.78, so EMI on $1 is

EMI on $1 = 8.78/1000 = 0.00878

EMI on $50150 is

EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32

Therefore the correct option is a.

Answer:

rate boat = 15 mph

rate current = 5 mph

explanation:

d = r * t

t = d/r

240 / (r_boat + current) = 12       Multiply both sides by r_boat + r_current.

240 = 12(r_boat + current)

240/ (r_boat - current) = 24       Multiply both sides by r_boat - r_current

240 = 24*(r_boat - current)    

Since the distances are the same in both equations, you can equate the right side of each.

12 (r_boat + current) = 24(r_boat - current)     Divide by 12

r_boat + current  = 2 (r_boat - current)             Remove the brackets.

r_boat  + current = 2*r_boat - 2* current          add 2 currents to both sides

r_boat  + 3currents = 2*r_boat                          Subtract r_boat both sides

3 currents = r_boat.

240 = 12*(r_boat + current.                               Divide by 12

20 = r_boat + current                                        Put 3 currents in for r_boat

20 = 3currents + 1 current                                Combine

20 = 4 currents                                                  Divide by 4

5 = current

The rate of the current = 5 miles / hour

3 currents = r_boat

3*5 = rate_boat

15 = rate of the boat

Answer:

cevap =560...........

Step-by-step explanation:

Question 1 (answer is C)

6 4

5 2

y=mx+b

4= 6m+b

2=5m +b

by subtracting the two equations

m= 2

4= 6(2)+b

b= 4-12

b= -8

y= 2x- 8

then the answer is C

Question 2

the answer is C

the answer is Cbecause the linear function has a power of (1)

Question 3(B)

m= -2

3 5

y=mx+b

5= 3(-2)+b

5= -6+b

b= 5+6

b= 11

y= -2x +11

the answer is (B)

Answer:

the area of the shape is 7.14

Step-by-step explanation:

First, find the area of the square:

2 in x 2 in = 4 in

then to find the area of the semi- circles add them together to make a circle

To find the area of the circle, use:

pi x radius^2  

Since the diameter is 2 divide the diameter by 2 to get radius  

3.14 x 1^2 = 3.14

The circle is 3.14 plus 4 ( the square ) = 7.14

Answer:

18.84

Step-by-step explanation:

Since the radius is 3 mili then we have to multiply 3 by 2 to get the diameter. Then multiple the diameter and pie 6×3.14 is 18.84.
