HELP NEEDED, GIVING BRAINLIEST!

Mathematics
1 answer:
Nataly_w [17]3 years ago
4 0

The correct answer is:

B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).

Step-by-step explanation:

Given

Dilation: D : (x,y) => (4x,4y)

And Vertices

A ( 2, 1 ), B ( 4, 1 ), C ( 4, -3 )

Applying dilation on all vertices

A ( 2, 1 ) => A'(4*2, 4*1) => A'(8,4)\\B ( 4, 1 ) = > B' (4*4 ,4*1) = > B'(16,4)\\C(4,-3) => C' (4*4 , 4*-3) => C'(16, -12)

To find the scale factor,

As we are multiplying each vertex coordinate by 4, the dilation factor is 4.

Moreover,

\frac{A'}{A} = \frac{(8,4)}{(2,1)} = (4,4)

Hence the scale factor is 4.

So,

The correct answer is:

B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).

What is 8 and 4/25 and as a mixed fraction or mixed number.
Sphinxa [80]

Answer:

Improper fraction for 8 4/25 is 204/25

Step-by-step explanation:

The numbers in the mixed fraction are defined as follow

8 = whole number

4 = numerator

25 = denominator

 Multiply the whole number by the denominator

8 × 25 = 200

Add the product from Step 1 to the numerator

200 + 4 = 204

Write answer from Step 2 over the denominator

204/25

The mixed number 8 4/25 converted to improper fraction is therefore :

Measuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate chang
dalvyx [7]

Answer:

A linear formula for S as a function of D is S=17D+1534

Step-by-step explanation:

We are supposed to find a linear formula for S as a function of D.

Equation of line : y = mx+c

We are given that At the surface, the speed of sound is 1534 meters per second.

c = 1534

We are given that for each increase in depth by 1 km, the speed increases by 17 m/s

So, Slope = m = 17

Substitute the values in equation

y=17x+1534

x denotes depth

y denotes speed

We are given that Use D for depth and S for the speed of sound

So, S=17D+1534

Hence a linear formula for S as a function of D is S=17D+1534
