5 0

Answer:

(2/3) + or - .943<em>i</em>

Step-by-step explanation:

Use quadratic formula.

x = \frac{-b \frac{+}{}\sqrt{b^2 - 4ac}  }{2a}

A = 3

B = -4

C = 4

\sqrt{16 - 2(3)(4)} = \sqrt{-8} or 2.828<em>i</em>

4/6= 2/3

Given the function g(x) = x2 + 10x + 20, determine the average rate of change of
Dmitrij [34]

A function assigns the values. The average rate of change for the given function g(x) is 1.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The average rate of change of a function is given by the formula,

Average rate of change, = [f(b)-f(a)]/(b-a), [a,b]

Where a is the lower limit and b is the upper limit.

Given the upper limit for the function is 0, therefore, the value of a is 0, similarly, the value of b is -9. Thus,

a = 0

g(a) = 0²+10(0)+20 = 20

b = -9

g(b) = (-9)²+10(-9)+20 = 11

The average rate of change for the function g(x), can be written as,

\text{Average rate of change}= \dfrac{g(-9)-g(0)}{-9-0}=\dfrac{11-20}{-9} = 1

Hence, the average rate of change for the given function g(x) is 1.

Find lim h→0 f(2+h)-f(2)/h if f(x)=x^2+x+1
bekas [8.4K]

Answer:

5

Step-by-step explanation:

\displaystyle \lim_{h \to 0} \frac{f(2+h)-f(2)}{h}

\displaystyle\lim_{h \to 0} \frac{(2+h)^2 + 2 + h + 1 - 2^2 - 2 - 1}{h}

\displaystyle\lim_{h \to 0} \frac{4 + 4h + h^2 + h - 4}{h}

\displaystyle\lim_{h \to 0} \frac{h^2 + 5h}{h}

\displaystyle\lim_{h \to 0} h + 5

= 5

The ratio of the angles of a triangle is 3:7:2. What is the measure of the largest angle?
rewona [7]

Answer:

here's the solution,

let the given ratios as constants, by multiplying with same variable x

the angles will be 3x , 7x and 2x

now, we know the sum of the given angles measures 180°, since the sum of measures of all interior angles of a triangle is 180°

=》3x + 7x + 2x = 180°

=》12x = 180°

=》x = 15°

so, the measures of each angle is :

3x = 15 × 3 = 45°

7x = 15 × 7 = 105°

2x = 15 × 2 = 30°

and now, we can observe that the largest angle is 105°
