The solution to the quadratic equation by using a numeric approach

are x = 6.3 and x = -31.3

Given the quadratic function expressed as;

0.02x²+ 0.5x - 4 = 0

Multiply through by 100 to have;

2x² + 50x - 400 = 0

Using the general formula to solve:

x = -50±√2500-4(2)(-400)/2(2)

x = -50±√2500+3200/4

x = -50±75.49/4

x = -31.3 or 6.3

Hence the solution to the quadratic equation by using a numeric approach

are x = 6.3 and x = -31.3

A function is created to represent the miles per gallon your car gets. What restrictions would be made to the domain?. a. The do
Ahat [919]

Answer: d. The domain would only include positive numbers.

Step-by-step explanation:

Given: A function is created to represent the miles per gallon your car gets.

Here, the independent variable = the amount of fuel the car gets in gallons.

and the dependent variable = the total miles of car travel .

We know that the domain of a function is a set of all values of independent variable.

Thus, the domain would only include positive numbers because the quantity of fuel in a car is never negative and it can be in fraction .

Hence, D is the right answer.

The sum of the angle measures of a triangle is 180°. Find the value of x . Then find the angle measures of the triangle.
Lady bird [3.3K]

Answer:

Step-by-step explanation:

The sum of the angle measures of a triangle is 180°. Find the value of x . Then find the angle measures of the triangle.

find the value of x

x + 2x + x + 8 = 180

4x = 180 - 8

4x = 172

x = 172 : 4

x = 43

find angles

2x = 43 * 2

2x = 86°

-------

x = 43°

--------

x + 8 = 43 + 8

x = 51°

-----------------------

check

86 + 43 + 51 = 180°

the answer is good

If ƒ(x ) = 3x + 1 and ƒ -1 = , then ƒ -1(7) =
Elden [556K]
F(x) = 3x + 1

let f(x) = y

y = 3x + 1

y - 1 = 3x

3x = y - 1

x = (y - 1)/3

From y = f(x),  x = f⁻¹(y) 

<span>x = (y - 1)/3
</span>
 f⁻¹(y)  = (y - 1)/3

f⁻¹(7)  = <span>(7 - 1)/3 = 6/3 = 2

</span>f⁻¹(7)<span> = 2</span>
