Answer: 4.3^{\circ}F


Step-by-step explanation:

Given: Yesterday the temperature at noon = 11.4^{\circ}F

If by the midnight, the decrease in the temperature = 15.7^{\circ}F

Now, let x be the temperature at midnight.

Then according to the question,

x=11.4^{\circ}F-15.7^{\circ}F\\\Rightarrow\ x=(11.4-15.7)^{\circ}F\\\Rightarrow\ x=4.3^{\circ}F

hence, the temperature at midnight= 4.3^{\circ}F

Answer: 1.5%

Step-by-step explanation:

The Pure Interest Rate refers to the rate in a theoretical market where there is no risk as economic conditions can be predicted with certainty.

Sadly, uncertainty will always exist but there are rates that are close enough to the Pure interest rate such as US Government Security rates.

The United States has never defaulted on a debt payment in the modern era and as such is known to offer the least risky rates in the world. The rate on US Securities can therefore be considered as close as possible to the pure interest rate.

Given the rates in the question, the Pure Interest rate would be the 20-year Treasury bond rate of 1.5%.

Find y. right triangles
Juli2301 [7.4K]

Answer:

√2

Step-by-step explanation:

Angle ( θ ) = 45

Hypotenuse side = 2

Opposite side = x

Formula : -

sin θ = Opposite side / Hypotenuse side

Note :

The value of sin 45 = 1/√2

sin 45 = x/2

1/√2 = x/2

Cross multiply,

x*√2 = 2*1

x√2 = 2

2 can be simplified as √2 * √2

x√2 = √2*√2

Divide √2 on both sides,

x = √2
