Answer:

x=NEGATIVE 1/2, POSITIVE 2

Step-by-step explanation:

Just use math.waycom

The non-negative zero of the function f(x) is x = 2.

The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

here, we have,

For a given function f(x), the "zeros" of the function are the values of x such that:

f(x) = 0

In this case, we have the function:

f(x) = 6*x^2 - 9*x - 6

If we want to find the zeros of this function, we need to solve:

f(x) = 0 =  6*x^2 - 9*x - 6

To solve this, we can use the Bhaskara's formula, which says that for a general quadratic equation:

0 = a*x^2 + b*x + c

The zeros are:

x = -b ±√b² - 4ac / 2a

In this case our equation is:

0 =  6*x^2 - 9*x - 6

then, in the above notation, we have:

a = 6

b = -9

c = -6

Replacing these in our general formula, we get:

x = 9±15 /12

Then we have two zeros:

x = (9 + 15)/12 = 24/12 = 2

x = (9 - 15)/12 = -6/12 = -1/2

But we want only the non-negative, so we can discard the second one.

Concluding, the non-negative zero of the function f(x) is x = 2.

Step-by-step explanation:

y=790x-175

Answer:

m<ACD = [tex]50^{o}[/tex]

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

<ACD = 180 - 130

<ACD = [tex]50^{o}[/tex]

With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is [tex]50^{o}[/tex].

Answer:

Step-by-step explanation:

Ratio = 4/7 : 1/8

        [tex]=\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}[/tex]

       = 32 : 7

[tex]\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}[/tex]

= 7 : 32

Ratio 4/7 over 1/8  is the multiplicative inverse of the ratio 1/8 over 4/7

Answer:

27/4

Step-by-step explanation:

In this question,

[tex]x = 3 \\ y = - 1[/tex]

So if we substitute this in the equation given below

[tex] {x}^{3} \div 3 - y[/tex]

So if we substitute the variables,

[tex] {3}^{3} \div 3 - ( - 1) \\ [/tex]

[tex]27 \div 4[/tex]

[tex] \frac{27}{4} [/tex]

Answer in the photo

Step-by-step explanation:

I day choice D.

Why D?

Well 103% = 1.03 as a decimal.

You are missing x in your equation.

The slope is 12 and y- intercept is -5.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y=12x−5

Now, from slope- intercept form

y = mx + b

where m is the slope and b is the y intercept.

Now, Comparing with given equation

m= 12 and b= -5

Hence, the slope is 12 and y- intercept is -5.

Answer:

  (b)  -15

Step-by-step explanation:

The area under the curve from -5 to +5 can be divided into two trapezoids. The one from x=-5 to x=1 has an area of ...

  A = 1/2(b1 +b2)h = 1/2(1 +6)(5) = 17.5

The one from x=1 to x=5 has an area of ...

  A = 1/2(4 +3)(-1) = -3.5

So, the total area from x=-5 to x=+5 is 17.5 -3.5 = 14. This is the amount by which f(x) increases from f(-5) to f(5). That is ...

  f(-5) +14 = -1

  f(-5) = -15

312.50

Step-by-step explanation:

8 , 20 , 50, 125 , 312.50

First term, a = 8

Second term, ar = 20

Find common ratio, r

Substitute a = 8 into second equation

ar = 20

8r = 20

r = 20/8

r = 2.5

Find the fifth term

ar⁴

= 8 * 2.5⁴

= 8 * 39.0625

= 312.50

Fifth term, ar⁴ = 312.50
