Answer:
1.6 cups
Step-by-step explanation:
Each batch needs 0.4 cups of sugar, and she is making 4 batches. Therefore, we can multiply 0.4 times 4 to find how much sugar is needed.
0.4*4=1.6
So, she needs 1.6 cups of sugar for 4 batches
STEP - BY - STEP EXPLANATION
What to find?
The the value of secθ.
Given:
(4, 3)
⇒(x, y) = (4, 3)
Step 1
Draw a sketch.
Step 2
Substitute the values into the trig. ratio formula below.

From the sketch above, opposite = 3 and adjacent = 4

Step 3
Find the value of the hypotenuse side using Pythagoras theorem.
let h be the hypotenuse side.

Hence, hypotenuse = 5
Step 4
Substitute the values into the formula below:

But,

ANSWER
secθ= 5/4
tanθ=3/4

Answer:
6π units
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Since we only require one half of the circumference, then
0.5C = πr
given diameter = 12 then r = 12 ÷ 2 = 6, then
arc length = π × 6 = 6π units
