Answer:

10.6

Step-by-step explanation:

1. First, we need to find which digits √(113) is between, and that would be 10 and 11.

2. Okay, so √(113) is between 10 and 11, meaning 113 is between 100 and 121.

3. Since 113 is a little over half between 100 and 121, let's multiply 10.6 by 10.6 to see how close we are to 113:

$10.6 * 10.6$
$112.36$

4. 112.36 is pretty close to 113, therefore, the dot on the number-line should be placed at 10.6.

The quadratic function in vertex form of a parabola vertex 1,1 and passes through 4,19

Grace [21]

Answer:

y = 2(x - 1)² + 1

Step-by-step explanation:

The equation of a quadratic function in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (1, 1), thus

y = a(x - 1)² + 1

To find a substitute (4, 19) into the equation

19 = a(4 - 1)² + 1

19 = 9a + 1 ( subtract 1 from both sides )

18 = 9a ( divide both sides by 9 ), thus

a = 2

y = 2(x - 1)² + 1 ← in vertex form

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ

Oksanka [162]

Standard form is ax+by=c

first we use
y-y1=m(x-x1)
a point is (x1,y1)
the slope is m

the slope between the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(1,1) and (3,4)
slope=(4-1)/(3-1)=3/2

a oint is (1,1) and slope is 3/2
y-1=3/2(x-1)
y-1=3/2x-3/2
solve for ax+by=c form, a is normally positive and a and b and c are whole numbers
times 2 both sides
2y-2=3x-3
minus 2y
-2=3x-2y-3
add 3
1=3x-2y
3x-2y=2

Which equation represents the difference quotient of f(x) for all nonzero values of h?

CaHeK987 [17]

Look at the graph thoroughly .

It passes through origin and given some points

(-1,1)

(1,-1)

(2,-2)

(-2,2)

We observe that

$\\ \sf\longmapsto f(x)=-x$

Hence whatever the function be the result will be -x

Option D is correct
