How do you simplify the value of (28x^4)÷(12x^3)?

1 answer:

5 0

$(28x^4) \div (12x^3) = \dfrac{28x^4}{12x^3} = \dfrac{4 \times 7x^4}{4 \times 3 x^3} = \dfrac{7}{3} x^{4-3} = \dfrac{7}{3} x$

Point Q is the center of dilation. Lines segment S U is dilated to form line segment S prime U prime. The length of Q S is 3 .2

tia_tia [17]

Answer:

Option C.

Step-by-step explanation:

It is given that the dilation rule is $D_{Q,2.5}$ . It means the center of dilatation is point Q and scale factor is 2.5.

Scale factor is the ratio of distance from center to the image of a point and distance from center to the corresponding point.

$\text{Scale factor}=\dfrac{QU'}{QU}$

It is given that QU=4 and scale factor = 2.5.

$2.5=\dfrac{QU'}{4}$

Multiply both sides by 4.

$2.5\times 4=QU'$

$10=QU'$

We know that

$UU'=QU'-QU$

$UU'=10-4$

$UU'=6$

The distance between U' and U is 6 units.

Therefore, the correct option is C.
