On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the t
nasty-shy [4]

Answer:

Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.

Step-by-step explanation:

Point B(-6, 1) to B'(-3, -2)

Steps to achieve B"

-6+a= -3 ⇒ a= -3+6= 3

1+b= -2 ⇒ b= -2-1= -3

-----------------

Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b): B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)

  • Step 2 Write two equations: Negative 6 + a = negative 2. 1 + b = negative 3.
  • wrong step

Step 3 Solve each equation: Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.

Step 4 Write the translation rule: (x, y) right-arrow (x + 4, y minus 4)

----------------

  • Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.

How do I get the Central angle?
melamori03 [73]

Answer:

199.8°

Step-by-step explanation:

The circle has radius r = 7 ft.

Now, the circumference of the circle is given by the formula C = 2πr

So, C = 2 \times \frac{22}{7} \times 7 = 44 ft.

Now, 44 ft arc length is equivalent to 360°  

Hence, 24.42 ft arc length is equivalent to \frac{360}{44} \times 24.42 = 199.8 degree.

Therefore, the central angle is 199.8° (Answer)
