\text{Hey there!}

\text{If k = 5 the replace the 'k' value with 5}

\text{4(5)}^2+3

\text{(5)}^2=5\times5=25

\text{4 (25)+ 3 = ?}

\text{4 (25) = 25 + 25 + 25 + 25 = 100}

\text{100 + 3 = 103}

\boxed{\boxed{\bf{Your\ answer: 103}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}

Answer:

103

Step-by-step explanation:

Evaluate 4k2 + 3

To evaluate 4k² + 3, when k = 5, which means when you sees k, put 5 in replacement

4k² + 3 = 4(5)² + 3

4(5×5) + 3

4(25) + 3

open the bracket

4 × 25 = 100

∴ 100 + 3 = 103

What is the measure of AC ? Enter your answer in the box.
andrezito [222]
To solve for AC in the given inscribed angle we proceed as follows:
An inscribed angle is an angle with its vertex "on" the circle formed by two intersecting chords as in our drawing. Thus here we shall use the formula:
Inscribed Angle=1/2 intercepted Arc
thus
m∠ABC=1/2mAC
thus plugging in our values we shall have:
4x-3.5=1/2(4x+17)
4x-3.5=2x+8.5
solving simplifying and solving for x we obtain
4x-2x=8.5+3.5
2x=12
hence
x=12/2
x=6°
