Answer:

see below

Step-by-step explanation:

Except for the stretch factor, your work is completely correct. Multiplying only the x-coordinate by a factor of 2 results in a horizontal stretch by that factor.

Your coordinates and graph are correct.

In the comparison, you just need to say what happened.

a company sells circular mirrors. the price P pounds is proportional to the square of its radius r cm. a mirror with radius 20cm

Sever21 [200]

Answer:

P = 0.09r²

Step-by-step explanation:

Price, p is proportional to the square of its radius, r

P = k*r²

a mirror with radius 20cm has a price of £36

P = k * r²

36 = k * 20²

36 = k * 400

36 = 400k

k = 36/400

k = 0.09

Substitute the value of k into the equation:

P = k * r²

P = 0.09 * r²

P = 0.09r²

Whats the next two terms in order are p+q, p , p-q

Law Incorporation [45]

Answer:

p - 2q and p - 3q

Step-by-step explanation:

A Series is given to us and we need to find the next two terms of the series . The given series to us is ,

$\rm\implies Series = p+q , p , p - q$

Note that when we subtract the consecutive terms we get the common difference as "-q" .

$\rm\implies Common\ Difference = p - (p + q )= p - p - q =\boxed{\rm q}$

Therefore the series is Arithmetic Series .

Arithmetic Series:- The series in which a common number is added to obtain the next term of series .

And here the Common difference is -q .

Fourth term :-

$\rm\implies 4th \ term = p - q - q = \boxed{\blue{\rm p - 2q}}$

Fifth term :-

$\rm\implies 4th \ term = p - 2q - q = \boxed{\blue{\rm p - 3q}}$

Therefore the next two terms are ( p - 2q) and ( p - 3q ) .

Amber, Bernie, and Carlos are working on a problem together. Their goal is to correctly apply the difference of cubes formula to

NeX [460]

Answer: Carlos is correct

Step-by-step explanation:

2x^5-250x^2

The first step is to factorize out 2x^2

2x^2(x^3-125)

This can be rewritten as

2x^2(x^3-5^3),

Recall, difference if cube (a^3-b^3)

= (a-b)(a^2 +ab + b^2)

from our equation,

a= x

b = 5.

So the difference of cubes will be

2x^2[(x-5) (x^2 + 5x + 5^2)]

=2x^2[(x-5) (x^2 + 5x + 25)]

Carlos followed these steps. So he is correct. Carlos is correct because he correctly factored the GCF, identified a and b, and applied the difference of cubes method.

Amber is incorrect because 125 is equal to b3, not b.

Bernie is incorrect because x2 is not the GCF of the polynomial. The GCF is 2x^2.

A waffle cone has a volume of 31.254 cubic centimeters and a radius of

arlik [135]

Answer:

4.78 cm

Step-by-step explanation:

The formula for the volume of a cone of radius r and height h is

V = (1/3)πr²h. Here, V = 31.254 cm³ and r = 2.5 cm.

We begin by solving V = (1/3)πr²h for the unknown height, h:

31.254 cm³ 3(31.254 cm³) 93.762 cm³

h = ------------------------ = -------------------------- = -------------------- ≈ 4.78 cm

(1/3)πr² π(2.5 cm)² 19.635 cm²
