Paulo uses an instrument called a densitometer to check that he has the correct ink colour. For this print job the acceptable ra

sattari [20]

If the range of the answer should be +/- 10% of the particular value, then you have to solve for the percentage of that particular value. Since the value given is 1.8, we thus want to find 10% of that: 1.8 * 10/100 = 0.18 Then, add this value to the original value of 1.8: 1.8+0.18 = 1.98 Next, subtract .18 from from the original value of 1.8: 1.8-0.18 = 1.62 The range will be between these two numbers, so the range is from 1.62 to 1.98.

A quadratic relation has zeros at 3 and –5. The parabola goes through the point (2, –14). What is the equation of the parabola i

olasank [31]

Answer:

$\displaystyle 2 {x}^{2} + 4x - 30 = 0$

Step-by-step explanation:

we are given the zeros and a point where it goes through of a quadratic equation

remember that when the roots are given then the function should be

$\displaystyle \: y = a(x - x_{1})(x - x_{2})$

where a is the leading coefficient and x1 and x2 are the roots

substitute:

$\displaystyle y = a(x - (3))(x - ( - 5))$

simplify:

$\displaystyle y = a(x - 3)(x + 5)$

now the given point tells us that when x is 2 y is -14 therefore by using the point we can figure out a

substitute:

$\displaystyle a(2 - 3)(2 + 5) = - 14$

simplify parentheses:

$\displaystyle a( - 1)(7) = - 14$

simplify multiplication:

$\displaystyle - 7a = - 14$

divide both sides by -7:

$\displaystyle a = 2$

altogether substitute:

$\displaystyle y = 2(x - 3)(x + 5)$

since it want the equation y should be

$\displaystyle 2(x - 3)(x + 5) = 0$

recall quadratic equation standard form:

$\displaystyle {ax}^{2} + bx + c = 0$

so simplify parentheses:

$\displaystyle 2( {x}^{2} + 2x - 15 ) = 0$

distribute:

$\displaystyle 2 {x}^{2} + 4x - 30 = 0$

hence,

the equation of the parabola in standard form is 2x²+4x-30=0

|x+12|+7 answerrrr please

Natasha2012 [34]

|x + 12| + 7

That's not an equation. It doesn't ask a question, and
it isn't looking for an answer.

It's an expression that stands for a number. The number it
stands for depends on the value of 'x', and if 'x' ever changes,
the value of the expression also changes immediately.
