f(x)=4x^2+2x-6.find the range of function f(x).

Answers

Answer 1

Answer:

y ≥ 6.25

Step-by-step explanation:

f(x)=4x²+2x-6

positive (4) leading coefficient, curve is left up and right up

x coordinate of vertex: x = - b/2a = - 2/2*4 = - 1/4  (-0.25)

y = 4*(-1/4)² + 2*(-1/4) - 6 = -6 1/4  (-6.25)  ... extreme

range: y ≥ - 6.25    [-6.25,∞)

F(x)=4x^2+2x-6.find The Range Of Function F(x).

Step-by-step explanation:

Y=a|x-h|+k
11. how does the value of k affect the graph?
12. how does the value of h affect the graph?
13. how do the sign and absolute value of A affect the graph?

Answers

Step-by-step explanation:

Given the general form of the absolute value function, y = a|x - h| + k

11. How does the value of k affect the graph?

The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up.  If k is negative, the function is translated |k | units down.

12. How does the value of h affect the graph?

The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right.  If h is negative, the function is translated |h | units to the left.

13. How do the sign and absolute value of A affect the graph?

The value of a determines whether the graph opens up or down.

If a is positive, the graph opens up.If a is negative, the graph opens down.

The value of a also makes the parent function wider or narrower.

If 0 < a < 1, the graph is wider than the parent function.If a > 1, the graph is narrower than the parent function.

One side of a triangle is X another is X+3 and the third is 2X-1. If the perimeter is 66 inches what is the length of each piece

Answers

Perimeter of a triangle is equal to the sum of measures of its three sides, that is :

[tex]x + x + 3 + 2x - 1 = 66[/tex]

[tex]4x + 2 = 66[/tex]

[tex]4x = 64[/tex]

[tex]x = 16[/tex]

so, the three sides are :

2. You will get a recurring decimal.

     0.933333333

3. The first digit after the decimal is in the position of the 'tenths'

      0.9

4. You should use only two digits after the decimal to calculate

The expression 4(19 + e2) + 3f at e = 13 and f = 16 is 804.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, we have to Evaluate the expression 4(19 + e2) + 3f when e = 13 and

f = 16 is the same as replacing the numerical values of e and f in the expression

4(19 + e2) + 3f which is,

= 4(19 + 13²) + 3×16.

= 4(19 + 169) + 48.

= 4(189) + 48.

= 756 + 48.

= 804.

Find the volume of a right circular cone that has a height of 10.6 m and a base with a
diameter of 18.5 m. Round your answer to the nearest tenth of a cubic meter.

Answers

The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,

V = 949.76cm³

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Height of cone = 10.6 m

Diameter of cone = 18.5 m

Hence, We can solve for radius as;

= 18.5/2

= 9.25

We know that;

Volume of a right circular cone is,

V = 1/3(πr²h)

Here, r = 9.25, h = 10.6, π = 3.14,

Hence, We get;

V = 1/3(3.14)(9.25)²(10.6)

V = 1/3(3.14)(85.5625)(10.6)

V = 1/3(2847.86225)

V = 949.287417

V = 949.76cm³

Thus, The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,

V = 949.76cm³

Step-by-step explanation:

The length of arc s is calculated as

circumference of circle × fraction of circle

The central angle subtended by arc s is 360° - 114° = 246° then

arc s = 2πr × [tex]\frac{246}{360}[/tex]

        = 2π × 9 × [tex]\frac{41}{60}[/tex]
