Answer:

7.9 units

Step-by-step explanation:

You are required to find the distance between the points P and Q whose coordinates are given:

P (0, 0), Q(-4, 7)

$QP= \sqrt{ {( - 4 - 0)}^(2) + ( {7 - 0})^(2) } \n \n = \sqrt{( - 4) ^(2) + {(7)}^(2) } \n \n = √(16 + 49) \n \n = √(63) \n \n = 7.93725393 \n \n = 7.9 \: units$

Round to the nearest hundredth. 7.546
A. 7.546
B. 7.55
C. 7
D. 7.5

Answers

7.55 would be correct because if there is a 5 or greater it goes up a number if it is a 4 or lower it stays the same

B. 7.55

7.546⇒the underlined is the hundredths place
When rounding it to nearest hundredth, you will look at the digit next to it at the right.
7.546⇒six is greater than 5 so the hundredths place would round up to the next digit which is 5.
$7.546-7.55$

Throughout this activity, the scale factor, n, has been a positive value. However, a scale factor for dilations can also be negative. When a set of coordinates on a preimage is multiplied by -n instead of n, the coordinates of the image rotate about the center of dilation by 180°. Consider all the potential intervals of n in the table. Enter information in the table to indicate whether the scale factor produces an enlargement, a reduction, or no size change. Also indicate whether the image rotates 180° about the center of dilation. The first one has been done for you.
