F(x)= 4x-1 I think so hope it will help you
Answer:
x=0.450765 or x=−0.950765
Step-by-step explanation:
14x² + 7x - 6
→ Find the product, sum and factors
Product = -6
Sum = 7
Factors = No factors
→ Since there are no factors utilise the quadratic formula

→ List the values of a, b and c
a = 14
b = 7
c= -6
→ Substitute into the formula

→ Simplify
x=0.450765 or x=−0.950765
Answer:
The interest rate is 7.58%
Step-by-step explanation:
Compound continuous interest can be calculated using the formula:
A = P
, where
- A is the future value of the investment, including interest
- P is the principal investment amount (the initial amount)
- r is the interest rate in decimal
- t is the time the money is invested for
∵ Angus has $3,000 he want to invest
∴ P = 3000
∵ The interest rate is compounded continuously
∵ Angus has $5,500 in 8 years
∴ A = 5500
∴ t = 8
→ Substitute them in the rule above to find r
∵ 5500 = 3000
→ Divide both sides by 3000
∴
= 
→ Insert ㏑ in both sides
∵ ㏑(
) = ㏑(
)
→ Remember ㏑(
) = n
∴ ㏑(
) = 8r
→ Divide both sides by 8
∴ 0.07576697545 = r
→ Multiply it by 100% to change it to a percentage
∴ r = 0.07576697545 × 100%
∴ r = 7.576697545 %
→ Round it to the nearest hundredth
∴ r ≅ 7.58
∴ The interest rate is 7.58%
36x2(for the total amount of yarn for the width) would be 72. 112-72=40. Since it is a rectangle and the width should both be the same size, the length should be 20 inches. (20+20+36+36=112, so 20 inches is the correct answer.
Answer:
5.50
Step-by-step explanation:
If three cones cost 8.25, then each cone should cost 2.75. (8.25 / 3 = 2.75)
Then 2 cones should cost 5.50 (2.75 x 2 = 5.50)
