Answer:

110

Explanation:

The angle is either 70 because it's a base angle or 40 because it is not. The sum of 70 and 40 is 110.

If f(x)=<br> 2<br> x + ax + b<br> x²-x+2<br> f(0) = 1 and ƒ'(0) = 1,find a +b
miv72 [106K]

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.

A prism has a height of 11.2 centimeters and an equilateral triangle for a base, where each base edge is 8 centimeters. find the
Mademuasel [1]

The volume of the triangular prism with the given height and base dimensions to the nearest hundredth is 310.38cm³.

<h3>What is a triangular prism?</h3>

A triangular prism is simply a three-dimensional solid with three rectangular sides and two triangular bases.

The volume of an equilateral triangular prism is expressed as;

V = (√3/4) × a² × h

Given the data in the question;

  • Height h = 11.2cm
  • Sides a = 8cm
  • Volume V = ?

We substitute our values into the equation above.

V = (√3/4) × a² × h

V = (√3/4) × (8cm)² × 11.2cm

V = (√3/4) × 64cm² × 11.2cm

V = 310.38cm³

Therefore, the volume of the triangular prism with the given height and base dimensions to the nearest hundredth is 310.38cm³.
