The square root of 83

Step-by-step explanation:

the slope is always the ratio "y coordinate change / x coordinate change" when going from one point of the line to another.

so, when going from (-2, 3) to (-3, 1)

x changes by -1 (from -2 to -3).

y changes by -2 (from 3 to 1).

therefore, the slope is

-2/-1 = 2/1 = 2

Answer:

the first blank is 120 then the second blank is 180

Step-by-step explanation:

For you to get those answers you can subtract 60 from 240 which gets you 180, then you subtract 60 again to get you 120, then again you will subtract 60 again and you will get 60.

Answer:

I believe it would be Option A) 38

Answer:

141°

Step-by-step explanation:

An octagon has 8 sides and 8angles so the sum of its interior angles is: (8-2)×180= 1080°

5x+133+16+126+162-12+30=1080°

5x=625

x=125°

x+16=141°

Answer:

Step-by-step explanation:

k/4+3=14

Move 3 over

k/4=11

Divide both sides by 4

k=11/4

k=2.75 or 2 3/4

Answer:

1808.64yarde cubed

Step-by-step explanation:

cylinder = 9(3.14(8^2))

9(3.14(64)) = 1808.64

Answer:

Yes it is possible

Step-by-step explanation:

Now, put it all together (9). Sin (A + B) is the two parts of the opposite - all divided by the hypotenuse (9). Putting that into its trig form: A very similar construction finds the formula for the cosine of an angle made with two angles added together.

Answer:

X=12

Step-by-step explanation:

First, take the term out parenthesis being careful to manage the sign of individual term carefully :

x+42+3x=90

Next , subtract 42 from each side of the equation to isolate the x term while keeping equation balance :

x+42-42+3x=90-42

x+0+3x=48

x+3x=48

(1+3)x=48

4x=48

Now, Divide both side of equations by 4 to slove of x while keeping equation balance :

4x/4=48/4

x=12

Here,

(12+42)+3*12=90

54+36

90

Answer:

4.5 > x

Step-by-step explanation:

19 > 2x + 10

19 - 10 > 2x + 10 - 10

9 > 2x

9/2 >2x/2

9/2 > x

or

4.5 > x

Answer:

In other words, the solution is the point where the two lines intersect. To verify whether a point is a solution to a system or not, we will either determine whether it is the point of intersection of two lines on a graph or we will determine whether or not the point lies on both lines algebraically

7874

7874 rounded to 1 sf

if the previous digit is 5 or more round up, if not keep it as it is.

1 sf= 8000

therefore, 7874 rounded to 1 sf is 8000.

Answer:

8000

Step-by-step explanation:

Since the leftmost 7 is in the thousands place, you need to round the number to the nearest thousand. The digit to the right of the first 7 is an 8, so 7 goes up 1 to 8.

Answer: 8000

Answer:

21

Step-by-step explanation:

The first thing we do is multiply -3 by -9 to get 27. (Two negatives multiplied cancels each other out). Now we solve for -1+27-5. The resulting answer is 21.

Using translation concepts, it is found that the transformations necessary to transform the graph of f(x) into that of g(x) are given as follows:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The original function f(x) is given by:

[tex]f(x) = \sqrt{x}[/tex]

The transformations are as follows:

Answer:

The vertex is (5, -9).

Step-by-step explanation:

One way of approaching this problem consists of finding the roots.  Seet the quadratic equal to zero and solve for x:  {2, 8}.

The axis of symmetry is exactly halfway between 2 and 8:  x = 5.

Now find the y-component of the vertex by evaluating f(5):

f(5) = (5 - 8)(5 - 2) = -9

The vertex is (5, -9).  This is the minimum value of the function.  The graph of this quadratic opens up.

==========================================================

Reason:

For choice A, the LCD is 30 since

We get 30 from the fact that 5*6 = 30. Notice 2/3 and 1/6 already have the LCD of 6. We could rewrite the 2/3 into 4/6 to help show this better. Effectively we want to find the LCD of 4/6, 1/6, 1/5

Cross choice A off the list because we want an LCD of 45 instead of 30.

--------------------

Choice B is the answer because

What we can do is find the LCD of 2/3 and 1/9 to get 9. The 2/3 turns into 6/9. This means we need to find the LCD of 6/9, 1/9, and 1/15

Multiply the two unique denominators to get 9*15 = 135, then divide by the GCF 3 to get 135/3 = 45.

Recall that LCD(x,y) = (x*y)/GCF(x,y)

--------------------

We can stop here since we know choice B is the answer.

But if you wanted to continue, then the LCD of 2/3, 1/5 and 1/3 is 3*5 = 15. This rules out choice C.

Choice D can be ruled out because the LCD is 27*7 = 189.

Answer:

4π

Step-by-step explanation:

the area (A) of each shaded sector is calculated as

A = area of circle × fraction of circle

the angle subtended at the centre of each sector = 180° - 160° = 20°

then area of 2 sectors

= 2 × π × 6² × [tex]\frac{20}{360}[/tex]

= 2 π × 36 × [tex]\frac{20}{360}[/tex]

= 2π × [tex]\frac{20}{10}[/tex]

= 2π × 2

= 4π

Answer:

80 degrees and 20 degrees.

Step-by-step explanation:

Isosceles means two angles are the same. If one angle is 80 degrees that means another angle is 80 degrees. The sum of all angles is 180 degrees. 80 degrees + 80 degrees = 160 degrees. After you do that you subtract 160 from 180 to get 20 degrees.
