Answer:

A

Step-by-step explanation:

The scale factor can be defined as the ratio of new dimension of an object after scaling to the original  dimension. The are of the new circle is 49 times the area of the original circle. The correct answer is option C.

Scaling factor is a conversion factor used to change the size of a figure without changing its shape. When the size of a figure is increased, it called scaled up and when it decreases it is called as scaled down.

Given that, Scale factor of circle = 7.

Since, the scale factor of a circle is the ratio of new radius to original radius.

The new radius of circle can be written as,

r' = 7r

Thus, the area of new circle is π × (r')^2= π × (49r^2).

Hence, the area of new circle is 49 times the original circle.

Answer:

652

Step-by-step explanation:

[tex]\sqrt{652 \times 652}[/tex] is equal to [tex]\sqrt{652^{2} }[/tex], and the square root of a number squared is always the original number, so [tex]\sqrt{652^{2} }[/tex] is equal to [tex]652[/tex].

Answer:

√{652×652}=√652²=±652

Step-by-step explanation:

(a)

The equation of a line in slope- intercept form is

y = mx + c

Given

y - 3 = - 4(x + 2) ← distribute

y - 3 = - 4x - 8 ( add 3 to both sides )

y = - 4x - 5 ← in slope- intercept form

(b)

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

From the slope- intercept form

y = - 4x - 5 ( add 4x to both sides )

4x + y = - 5 ← in standard form

27a + 9b + c is reminder

Step-by-step explanation:

Remainder theorem says that when p(x) is divided by (x – a) the remainder is given

by p(a)

Let p(x) = ax³ + bx²+ c

P(x) when divided by (x – 3)

Using Remainder theorem, we have

Remainder = p(3) = a(3³) + b(3²) +c

= 27a + 9b + c

Answer:

[tex]842\ \text{ft}[/tex]

[tex]y(t)=906-16t^2[/tex]

Step-by-step explanation:

Let [tex]y[/tex] be the height the object from the ground.

[tex]s[/tex] be the initial height of the object = 906 ft

[tex]u[/tex] = Initial velocity = 0

[tex]g[/tex] = Acceleration due to gravity = [tex]32\ \text{ft/s}^2[/tex]

[tex]t[/tex] = Time

The expression would be

[tex]y(t)=s-ut-\dfrac{1}{2}gt^2\\\Rightarrow y(t)=906-16t^2[/tex]

The required expression is [tex]y(t)=906-16t^2[/tex]

At [tex]t=2\ \text{s}[/tex]

[tex]y(2)=906-16\times 2^2\\\Rightarrow y(2)=842\ \text{ft}[/tex]

The height of the object after 2 seconds of falling is [tex]842\ \text{ft}[/tex].

Answer:

Each orange would cost $0.64.

Step-by-step explanation:

If you do 3.84 and divide that by 6, you would get the answer of $0.64 for each orange.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The cost of one orange is $0.64

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

6 oranges = $3.84

Divide both sides by 6.

1 orange = $3.84/6

1 orange = $0.64

Thus,

The cost of one orange is $0.64.

Answer: 1770 rupees

Step-by-step explanation:

To solve this, we first calculate the simple interest which will be:

= (P × R × T) / 100

= (1500 × 9% × 2) / 100

= (1500 × 0.09 × 2) / 100

= 270

The total amount tha she'll get will be:

= 1500 + 270

Answer:

x = 31.4

PQ = 58.8

Step-by-step explanation:

Set up a proportion:

SQ/QP = ST/PR

Substitute in the values they give you:

[tex]\frac{x-9}{x-9+x+5} = \frac{8}{21}[/tex]

[tex]\frac{x - 9}{2x - 4} = \frac{8}{21}[/tex]

[tex]21x - 189 = 16x - 32\\5x = 157\\x = 31.4[/tex]

This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8

Answer:

x = 15, PQ = 26

Step-by-step explanation:

x+13/9 = 21/x-9

x^2+4x−117=168

x^2+4x−285=0

(x−15)(x+19)=0

x=15

it cannot be a negative number so x cannot be -19

PQ= x+13

15+13=26

Answer:

x = 44

Step-by-step explanation:

You can rewrite logarithm equations like so:

[tex]log_{b}(x) = y\\\\x = b^y[/tex]

A way to remember this is the base in the logarithm is also the base in the exponent - then remember this base b is to the power of what's on the other side - and all this is equal to whatever's in the parentheses.

In this case,

[tex]log_3(2x-7) = 4\\2x - 7 = 3^4\\x = (3^4 + 7)/2 = 44[/tex]
