Answer:

Bruno is correct. When going from a larger unit to a smaller unit you need to divide

Step-by-step explanation:

Sam's calculation:

45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 × 0.621 = 77.38 kilometers.

Bruno's calculation:

45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64 kilometers.

1 kilometer = 0.621 miles.

Bruno is correct. When going from a larger unit to a smaller unit you need to divide

We will divide a larger value by a smaller value to get the smaller units

Step-by-step explanation:

Answer:

1,2,4,8,16.

Step-by-step explanation:

they are a square root of 2 for each question. it will eventually get up higher then additive.

The sequence that has the second greatest value for the 10th term is

 1, 2, 4, 8, 16, . . .

The geometric sequences in the given sequences is  1, 2, 4, 8, 16, . . .

A sequence  is an enumerated collection of objects in which repetitions are allowed and order matters.

Now the given sequences are,

30, 40, 50, 60, 70, . . . :
0, 5, 15, 30, 50, . . . :

1, 2, 4, 8, 16, . . .

For sequence 30, 40, 50, 60, 70, . . . :

we have common difference, d = 10

So, this is an arithmatic sequence.

So, Tn = a1 + (n-1)d

Hence, 10th term of the series,

T10 = 30 + (10-1)10

T10 = 30 + 9*10

T10 = 30 + 90

T10 = 120

For sequence 0, 5, 15, 30, 50, . . .

This is a recurssive sequence

Hence each term of the series is given as,

0

5 = 5*1

15 = 5*(1 + 2)

30 = 5*(1 + 2 + 3)

50 = 5*(1 + 2 + 3 + 4)

.

.

.

.

.

10th term = 5*(1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 +  9)

10th term = 225

For sequence 1, 2, 4, 8, 16, . . .

Here common ratio, r = 2

also, Tn = ar^(n-1)

So, T10 = 1*2^(10-1)

or, T10 = 1*2^9

or, T10 = 512

Therefore,

The sequence that has the second greatest value for the 10th term is

 1, 2, 4, 8, 16, . . .

and The geometric sequences in the given sequences is

1, 2, 4, 8, 16, . . .

8[tex]x^{6}[/tex] + 12[tex]x^{4}[/tex]y² + 6x²[tex]y^{4}[/tex] + [tex]y^{6}[/tex]

Step-by-step explanation:

This can be expanded using the binomial theorem or by multiplying the factors.

In case you are not aware of the theorem, will do multiplication.

Given

(2x² + y²)³ = (2x² + y²)(2x²+ y²)(2x² + y²)

Expanding the second pair of factors

Each term in the second factor is multiplied by each term in the first factor, that is

2x²(2x² + y²) + y²(2x² + y²) ← distribute both parenthesis

= 4[tex]x^{4}[/tex] + 2x²y² + 2x²y² + [tex]y^{4}[/tex] ← collect like terms

= 4[tex]x^{4}[/tex] + 4x²y² + [tex]y^{4}[/tex]

Now multiply this by the remaining factor (2x² + y²)

(2x² + y²)(4[tex]x^{4}[/tex] + 4x²y² + [tex]y^{4}[/tex])

= 2x²(4[tex]x^{4}[/tex] + 4x²y² + [tex]y^{4}[/tex]) + y²(4[tex]x^{4}[/tex] + 4x²y² + [tex]y^{4}[/tex]) ← distribute both parenthesis

= 8[tex]x^{6}[/tex]+ 8[tex]x^{4}[/tex]y² + 2x²[tex]y^{4}[/tex] + 4[tex]x^{4}[/tex]y² + 4x²[tex]y^{4}[/tex] + [tex]y^{6}[/tex] ← collect like terms

250 berries

Step-by-step explanation:

There are 10 berries to every orange there is. It is given that there are 25 oranges. Simply multiply 10 with 25:

10 x 25 = 250

There are 250 berries.

~

Answer:

There are 250 berries.

Step-by-step explanation:

There are 10 berries per 1 orange.

We have 25 oranges.

To find out how many groups of berries to oranges there will be I will divide 25 by 1.

[tex]25/1=25[/tex]

[tex]x*y=z[/tex]

x = Amount of groups

y = Amount of berries per group

z = Amount of berries total.

Substitute values:

[tex]25*10=250[/tex]

There are 250 berries total!

Answer:

This transformation is a  horizontal stretch  by a factor of  2 .

Step-by-step explanation:

The transformation is a horizontal stretch by a factor of 2 .

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

According to the given figure, vertices of rectangle ABCD are:

A=(3,0) B=(1,0) C=(1,2) and D=(3,2)

After the transformation of square ABCD we get a rectangle A′B′C′D′.

whose vertices are, A'=(6,0) B'=(2,0), C'=(2,2) and D'=(6,2)

(Here A', B', C' and D' are transformed from points A, B , C and D respectively.

In horizontal stretch by a factor k the point (x,y) in a graph f(x) is transformed to the (kx,y).

And after seeing the coordinates of vertices of square ABCD and rectangle  A′B′C′D′

it is clear that there is no change in the y-coordinates in all the vertices of both square ABCD and rectangle  A′B′C′D'.

Moreover, the x-coordinates are increasing by multiplying 2. Therefore it is a horizontal stretch by factor 2.

Hence, this transformation is a horizontal stretch by a factor of 2 .

Answer:

y = -5/4x - 10.75

Step-by-step explanation:

First, put the equation in slope intercept form by isolating y:

5y - 4x = 10

5y = 4x + 10

y = 4/5x + 2

Perpendicular lines have opposite reciprocal slopes, so the slope will be -5/4

Plug in the slope and the given point into y = mx + b to find b:

y = mx + b

8 = -5/4(-15) + b

8 = 18.75 + b

-10.75 = b

Plug in the slope and y intercept into y = mx + b

y = mx + b

y = -5/4x - 10.75

Answer:

5x + 4y + 43 = 0

Explanation:

y=mx+b

m=slope

b=y intercept

perpendicuar lines have slopes that multiply to get -1

so

solving for y

add 4x both sides and divide by 5 to get

y=4/5x+2

slope is 4/5

perpendicular means the slopes multiply to get -1

so

4/5 times what=-1?

what=-5/4

so

y=(-5/4)x+b

find b

given the point (-15,8)

8=(-5/4)(-15)+b

8=75/4+b

-43/4=b

y=(-5/4)x-43/4

convert to standard form:

5x + 4y + 43 = 0
