cups of brown sugar needed for only 1 cup of flour
<em><u>Solution:</u></em>
To make banana bread, Colin uses of a cup of brown for every 2 cups of flour
To find: Amount of brown sugar should Colin use to make a small batch with only 1 cup of flour
Let "x" be the amount of brown sugar needed for only 1 cup of flour
From given information,
This forms a proportion and we can solve the sum by cross multiplying
Thus cups of brown sugar needed for only 1 cup of flour

Answer with explanation:
The equation using trigonometric function are whose value we have to evaluate in the interval [0, 2π].
1.→
cos²x +2 cos x=3
→cos²x +2 cos x-3=0
→cos²x +3 cos x-cos x-3=0
→cos x ( cos x +3) -1×(cos x +3)=0
→ (cos x -1)(cos x +3)=0
→cos x -1= 0 ∧ →cos x+3=0
→cos x =1 ∧ → cos x = -3
⇒-1 ≤ cos x ≤ 1
→cos x=1
where, n is any integer.
→Solution in the Interval [0, 2π] is , x=0, 2 π
2.
2 sin² Ф +7 sin Ф =4
→2 sin² Ф +7 sin Ф -4=0
→2 sin² Ф +8 sin Ф- sin Ф -4=0
→2 sin Ф × (sin Ф +4) -1 × (sin Ф +4)=0
→ (2 sin Ф -1)(sin Ф +4)=0
→ 2 sin Ф -1=0 ∧ →sin Ф +4=0
→sin Ф ≠ -4≡→ ∵ -1 ≤ sin Ф ≤ 1
Where , n is any Integer.
3.
→tan² x+4=2 sec² x+tan x
→tan² x+4=2(1+tan²x)+tan x
→2 tan²x -tan²x +tan x +2-4=0
→tan²x +tan x -2=0
→tan²x +2 tan x -tan x -2=0
→tan x (tan x +2) -1×(tan x +2)=0
→(tan x-1)(tan x +2)=0
→tan x-1 =0 ∧ tan x +2=0
→tan x=1 ∧ tan x = -2
→tan x=1
→tan x= -2
where, k and n are integer.
Answer:
Option (A)
Step-by-step explanation:
From the figure attached,
By applying triangle sum theorem in ΔBCP,
m∠CBP + m∠CPB + m∠BCP = 180°
15° + 20° + m∠BCP = 180°
m∠BCP = 145°
m∠ACB + m∠BCP = 180° [Linear pair of angles are supplementary]
m∠ACB + 145° = 180°
m∠ACB = 35°
Since, ∠ACB is the inscribed angle and AB is the intercepted arc.
Therefore, m(arc AB) = 2m(∠ACB)
m(arc AB) = 2 × 35°
= 70°
Therefore, Option (A) is the correct option.
