Answer:

160 sq cm

Step-by-step explanation:

Since the two trapezoids are similar, you can use a ratio to find the area.

If we use x to represent the area of ABCD, then the ratio will look something like:

5/20 = 40/x

which then we can solve x to be 160 sq cm.

The graph of Y = COS X+ż is the graph of the y = cos(x) shifted in which direction?
rjkz [21]

Answer:

2 units up

Step-by-step explanation:

You're just taking the  entire graph of cos(x) and then adding 2 so it moves everything up.  If you added 2 to x BEFORE taking the cosine

(like y = cos (x+2) ), then you would shift it left 2.  Adding and subtracting from the x moves everything left or right.  Adding or subtracting at the end just moves it up and down.

Some number was divided into 104.13. This quotient was multiplied by 4, after which the resulting product was added to 5. Given
SVEN [57.7K]

Answer:

The initial number is <u>-1218.321</u>.

Step-by-step explanation:

Let the initial number be 'x'.

The number 'x' is divided into 104.13.

So, we divide the number 'x' by 104.13. This gives,

\dfrac{x}{104.13}

Now, the quotient is multiplied by 4. So, this means we need to multiply 4 to the fraction above. This gives,

\dfrac{x}{104.13}\times 4\\\\\frac{4x}{104.13}

Now, 5 is added to the result. This gives,

\frac{4x}{104.13}+5

Now, as per question:

\frac{4x}{104.13}+5=-41.8

Now, solving for 'x', we add -5 both sides. This gives,

\frac{4x}{104.13}+5-5=-41.8-5\\\\\frac{4x}{104.13}=-46.8\\\\4x=-46.8\times 104.13\\\\4x=-4873.284\\\\x=\frac{-4873.284}{4}=-1218.321

Therefore, the initial number is -1218.321.

Alina [70]

Answer:

(4,-3)

Step-by-step explanation:

If you graph this point, then it will be in the 3rd quadrant.

A 180 degree rotation will put it in the 1st quadrant.

And the extra 90 degrees will put in in the 4th quadrant, so we know that in (x,y), x is positive, and y is negative. then if you theoretically rotate it, since you are rotating it 90 degrees, 3 times, you will have to switch the x and y, since 3 is an odd number. so the final answer is (4,-3).

Let ​ f(x)=x^2−3x−4​ . What is the average rate of change from x = 7 to x = 10?
Stells [14]
So, this is the answers you get from plugging in x = (7 through 10)
x = 7 ... 24
x = 8 ... 36
x = 9 ... 50
x = 10 ... 66

Then you get the rate of changes...

66 - 50 = 16
50 - 36 = 14
36 - 24 = 12

So the average of 16, 14 and 12 (those values added together and then that total divided by the number of values, which is 3) is 14

The average rate of change is 14
