Answer 1

Answer:

Answer:

90 degree

Step-by-step explanation:

Three points A, B, and C are added and shown in attached picture.

As the property of inscribed angle in circle:

angle BAC = (1/2) x 88 = 44 deg

As the property of complement angle:

angle ABC = 180 - 89 = 91 deg

As the property of sum of three angles in a triangle:

angle ACB + angle ABC + angle BAC = 180 deg

=> angle ACB = 180 - angle ABC - angle BAC = 180 - 44 - 91 = 45 deg

One more time, we use the property of inscribed angle in circle:

x = 2 x angle ACB = 2 x 45 = 90 deg

Hope this helps!

In which quadrant of the coordinate plane is the point (−4,1) located

Answers

Answer:

Quadrant II

Step-by-step explanation:

Below will be a picture provided to show you which quadrants are in a coordinate grid.

To graph (-4, 1) we will start at the origin, go 4 units to the left and 1 unit up.

As you can see in the image, it will be plotted in quadrant 2.

Best of Luck!

Answer:

quadrant II or 2

Step-by-step explanation:

I'm not sure if your teacher wants in Roman Numerals or not.

in quadrant II/2 x is negative (on the left side of the y-axis) and y is positive (above the x-axis)

Which is the solution to the system of equations?y = 1/8x - 1
-5x + 4y = -13
A. (0, -1)
B. (8,0)
C. (1, -7/8)
D. (2, -3/4)

Answers

Answer:

D. (2, -3/4)

Step-by-step explanation:

Using the substitution method:

-5x+4(1/8x-1)=-13

-5x+0.5x-4=-13

-4.5x/4.5=-9/4.5

-x=-2

x=2

You are supposed to replace 2 in the first equation now but as there is no other option with x value of 2 D is the answer.

If continued:

-5(2)+4y=-13

-10+4y=-13

4y=-3

y=-3/4

Answer that please! Thanks

One way to find the area of this shape is to add up the areas of all of the interior shapes. To find the area of a triangle, we use the formula A=1/2bh. To find the area of a square, we use the formula A = s^2.

We will begin by finding the area of the triangle on the left side of the figure.

A = 1/2bh= 1/2(2)(2)= 1/2(4)= 2 units^2

Then we can do the same for the triangle on the right side of the figure.

A = 1/2bh = (1/2)(4)(2) = (1/2)(8) = 4 units^2

Finally, we can find the area of the inner square.

A = s^2 = 2^2 = 4 units^2

Now, we must add up the areas of these smaller shapes to find the total area.

A = 2 + 4 + 4 = 10 units^2

Therefore, your answer is 10 units^2.

Hey here is the answer to ur question....!
Given:
AC=2
BC=2
BE=2
DE=2
DF=4
Angle DCB=angleCBE=angleBED
To find: area of the given figure
Solution: in BEDC,
Since BE=2
=>CD=2 (Opposite sides are equal in a square)
Therefore ,area of square BEDC=s*s=2*2=4 units^2
In triangle ABC,
AC=CB=2
=>area of triangle =1/2*b*h
=>area of triangle ABC=1/2*2*2
=>area of triangle =2 units^2
In triangle DEF,
DF=4
DE=2
=>area of triangle DEF=1/2*4*2
=>area of triangle DEF=4units ^2
Therefore ,area of the given figure ABEF=area of triangle ABC+area of triangle DEF+area of square BEDC
=>2+4+4
=>area of the given figure ABEF=10 units^2

The population of bacteria M after X minutes is represented by the function M(x)=51(1.03)^x.whqt is the approximate difference between the populations after 3 minutes

Answers

The difference between the populations after 3 minutes is 5.

Population of bacteria

According to the question, the population of bacteria is modeled by the function; $M(x)=51(1.03)^x$ . We have to recall that x refers to the time taken to have an M number of bacteria.
