40sec→1DVD
60sec→XDVD
40:1=60:x, 40*x=1*60, x=1.5
Jaytree's "ripping rate" is 1.5DVD/min

If f(x) = x ² +1 and g(x) =3x+ 1,find [f(4)] ²
guajiro [1.7K]

Answer:

289

Step-by-step explanation:

We don't need g at all for this.

We will need to know f(4) before continuing...

f(4) can be found by replacing x in f(x)=x^2+1 with 4:

f(4)=4^2+1

f(4)=16+1

f(4)=17

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

Now let's find [f(4)]^2:

[f(4)]^2

[17]^2

17(17)

help PLEASEE! Might post a lot of these sorry
ExtremeBDS [4]

Answer:

A = 189 sq units

Step-by-step explanation:

You can cut the shape up into pieces. See image. There are two rectangles and a triangle. Some sides are given:

rectangle: 16 × 8

sm rectangle: 3 × 4

Some sides you have to add to find (the height of the whole entire thing: 16+4+4)

Some lengths you have to subtract to find (height of the triangle: 24 - 10).

Area of a rectangle:

length × width OR

base × height

Area of a triangle:

1/2 • b • h

Add up all three areas. See image.

What is the area? Round to the nearest tenth
Tamiku [17]

Answer:

60.8 mm^2

D

Step-by-step explanation:

Remark

You have to assume that the left and right sides are both 9.3. The question is undoable without that assumption.

Next, you have to assume that The top is 7.8 mm across and both ends meet 9.3 at right angles. Again if that is not true, the problem can't be done. Sometimes people making these questions make errors which you are asked to correct.

Solution

So let's assume that everything I've assumed is correct.

Find the area of the rectangle.

Area = L*W

L = 9.3

W = 7.8

Area = 7.8 * 9.3

Area = 72.54        Do your rounding at the end.

Now find the are of the triangle that has been cut out.

The height = 3

The base = 7.8

Area = 1/2 b * h

Area = 1/2 7.8 * 3

Area = 11.7

The area of the figure = area of the rectangle - the triangle's area

Figure Area = 72.54 - 11.7

Figure Area = 60.84
