Answer:
There is no short answer.
Step-by-step explanation:
To find to intervals which f(x) increases or decreases, we first need to find it's derivative.
The function is increasing when it's value is > 0 and decreasing when it's value is < 0.
If we take a look at this graph, cosx+sinx is positive when they are both positive or when cosx is greater then sinx on the negative part.
I hope this answer helps.
Answer:
£10,200
Step-by-step explanation:
Simple interest = principal × rate × time
Principal = £6000
Rate = 7% = 0.07
Time = 10 years
Simple interest = principal × rate × time
= £6000 × 0.07 × 10
= £4,200
Total = simple interest + principal
= £4,200 + £6,000
= £10,200
He would have to pay back a total of £10,200 in 10 years

Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
0=2x²−10x+7
Step 1: Subtract 2x^2-10x+7 from both sides.
0−(2x²−10x+7)=2x²−10x+7−(2x²−10x+7)
−2x²+10x−7=0
For this equation: a=-2, b=10, c=-7
−2x²+10x+−7=0
Step 2: Use quadratic formula with a=-2, b=10, c=-7.
hey! the value of y is 57
