To find the values of a and b, we can use the given information about the function f(x) and its derivatives at x = 0.

First, we know that the value of f(0) is 1, which means that when we plug x = 0 into the function, we get f(0) = 20 + a0 + b*0^2 - 0 + 2 = 1. Solving this equation for b, we get b = -1.

Next, we know that the derivative of the function f(x) at x = 0 is ƒ'(0) = 1. The derivative of a polynomial function is given by ƒ'(x) = 2x + ax + bx^2 - 1. Plugging in x = 0, we get ƒ'(0) = 20 + a0 + (-1)*0^2 - 1 = 1. Solving for a, we get a = 1.

Therefore, the values of a and b are a = 1 and b = -1. The sum of these values is a + b = 1 + (-1) = 0.

dangina [55]

Answer:

The value of a is 150 and b is 4822.

Explanation:

First, you have to expand to remove brackets :

(5372 + 100 {y}^{2} ) + 5(10 {y}^{2}  - 110)

= 5372 + 100 {y}^{2}  + 50 {y}^{2}  - 550

Next, you have to simplify :

100 {y}^{2}  + 50 {y}^{2}  + 5372 - 550

= 150 {y}^{2}  + 4822

Next, you have to compare it :

a {y}^{2}  + b = 150 {y}^{2}  + 4822

a = 150

b = 4822

ruslelena [56]

Baker, Schultz, and Halstead argue that the united states could exploit significant strategic and economic gains if it invests in cleaner energy technologies and supports international efforts to reduce carbon emissions.

The statement is false.

According to early projections from the US Energy Information Administration, cleaner renewable energy accounted for around 12.6% of total primary energy consumption and about 19.8% of domestically produced power in the US in 2020.

The policy, which was based on an economic model created by Resources for the Future, would cut carbon emissions by 50% by 2035.

The Council, which was established in 2017 by Ted Halstead, former Republican Secretaries of State James Baker and George Shultz, has put together a coalition of businesses, environmental organisations, economists, and other individuals to advocate their climate plan.

The complete question is:

Baker, schultz, and halstead argue that the united states could exploit significant strategic and economic gains if it invests in cleaner energy technologies and supports international efforts to reduce carbon emissions. True or false?
