Answer:

(7-8) / (-7/16) = -2 -(.8) + (1/4) = -.55 -2+ -.55= -2.55

Step-by-step explanation:

The parameter of the shaded shape is 50 meters

The parameter of any shape is sum of all sides

Measurements of some of the sides are given and some needs to be find out so the calculations are -

first side = 7m

second side = 14m

third side is equal to first side so= 7m,

fourth side = 1m

fifth side is equal to seventh side =4m

sixth side is second side- fourth side- eighth side = 14- 1-4= 9m

seventh side=4m

eighth side =4m

parameter of the shape = sum of all side = 7+ 14+ 7+ 1+4+9+4+4

                                     =50 m

So, the parameter of the shaded shape is 50 meters

The domain of f(x) is all real numbers & satisfies function f(x+1)=2f(x).

For  x∈(0,1], the function f(x)=x(x-1). For value x∈(-[tex]\infty[/tex],m], f(x)≥[tex]\frac{-8}{9}[/tex]. What is the value of m?​

the smallest value m=[tex]\frac{7}{3}[/tex].

Given that, for x∈(0,1], f(x)=x(x-1)

Let's plot this function

We'll go from 0 to 1 and let's graph what this function is look like

f(x)=x(x-1) will be a parabola and it's going to go between the points (0,0) and (1,0).

Will graph it in figure1 we can see.

The minimum value of this parabola is right in the middle and it is

f(0.5)=-0.25

Now, let try and graph the function in the other intervals

We know f(x+1)=2f(x)

Now we can evaluate couple of points

f(0+1)=2f(x)

f(0.5+1)=2f(0.5)

f(1+1)=2f(1)

And we quickly deduce that the graph in(1,2] is twice the height of the graph in (0,1].

We will graph a parabola in figure 2 we can see.

This parabola is going to have a graph of 2 between its twice as tall and this can be multiplied by the quantity of (x-1) multiplied by the quantity of (x-2).

It is 2(x-1)(x-2).

We graph next interval twice the height of the graph in the interval from 2 to 3. We can see the graph in figure3.

This parabola will have an equation 4 times the quantity of (x-2) and (x-3).

We can also shift this graph to the left and it going to be half the height.

Looking at this graph we want f(x)≥[tex]\frac{-8}{9}[/tex].

In the 3 interval from 2 to 3 its going to intersect .

we want to look for the points where f(x)≥[tex]\frac{-8}{9}[/tex].

We are looking for m which f(x)≥[tex]\frac{-8}{9}[/tex].

parabolas equation =[tex]\frac{-8}{9}[/tex].

4(x-2)(x-3)=[tex]\frac{-8}{9}[/tex]

[tex]x^{2} -5x+6=\frac{-2}{9} \\(x-\frac{7}{3})(x-\frac{8}{3})=0\\ x= \frac{7}{3},\frac{8}{3}\\\\[/tex]

Answer: 236 square inches

Step-by-step explanation:

Three 6" x 6" and two 8" x 8" electrical boxes are installed in a wall between two studs

The answer is 236

6x³ + 2x² + 3x - 4 is not exactly divisible by x² + 3x - 4.

Given,

The expression : 6x³ + 2x² + 3x - 4

We have to divide the given expression by x² + 3x - 4.

Let's take 6x³ + 2x² + 3x - 4 as p(x) and x² + 3x - 4 as g(x).

If p(x) is divisible by the factors of g(x), then p(x) is divisible by g(x).

So, let's factorize  x² + 3x - 4

x² + 3x - 4 = (x - 1) (x + 4)

Now,

p(x) = 6x³ + 2x² + 3x - 4

By using remainder theorem,

If p(1) = 0 and p(4) = 0, then p(x) is divisible by g(x).

So,

p(1) = 6 × 1³ + 2 x 1² + 3 x 1 -4

p(1) = 6 + 2 + 3 - 4

p(1) = 11 - 4

p(1) = 7

Next,

p(4) = 6 x 4³ + 2 x 4² + 3 x 4 - 4

p(4) = 6 x 64 + 2 x 16 + 12 - 4

p(4) = 384 + 32 + 12 - 4

p(4) = 424

Here, p(1) and p(4) is not 0.

So, p(x) is not divisible by g(x).

That is, 6x³ + 2x² + 3x - 4 is not exactly divisible by x² + 3x - 4.

Answer:

y = -4x - 1

Step-by-step explanation:

Let's first find the equation of the line segment AB. The equation of a line in slope-intercept form is y = mx + b where m represents the slope and b represents the y-intercept. Start by finding the slope.

The equation for slope is:  [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. These variables represent any pair of coordinates on the line. In this case since the two points chosen are A and B, thus:

[tex]x_2=-2\\x_1=3\\y_2=15\\y_1=-5[/tex]

If we plug these values into the equation, we get:

[tex]\frac{15-(-5)}{-2-3}=\frac{20}{-5}=-4[/tex]

Now we need to find the equation of a line that passes through the point (-1, 3) and is parallel to AB. If two lines are parallel they share the same slope. The equation of the line parallel to AB is y = -4x + b. We can plug in the coordinate (-1, 3) into the equation to solve for b.

[tex]y = mx+b\\3 = -4(-1) +b\\3=4+b\\\text{Subtract 4 from both sides}\\b=-1[/tex]

Therefore the equation of the line that passes through the point (-1, 3) and is parallel to AB is y = -4x - 1.

(h) x = 3 which is a relative maximum point

(i) the value of x is 3 for which f(x) = 3

(j) the function would be positive if f(0)

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The domain of the function shown in the graph is given by the set of values x that has a point on the graph.

In other words, by launching the graph onto the x-axis we will cover the interval (−3,6]

The range of the function shown in the picture is given by the set of values y that has a point on the graph.

In other words, by launching the graph onto the y-axis we will cover the interval (−6,3]

The zeros of the function are the x-intercepts of the function, so the zeros are x = −0.5 and x=6.

The value of f(-3.5) is given by the y- coordinate of the point of intersection of the graph with the vertical line x=-3.5 So, f(-3.5)≈2.

The function is increasing whenever the y- coordinate increases if we trace the graph in the direction of positive x values.

So, the graph is increasing on (−3,3), where x=3 corresponds to the x- coordinate of the turning point on the graph.

The function is decreasing whenever the y- coordinate decreases if we trace the graph in the direction of positive x values.

So, the graph is decreasing on (3,6].

The values of x where f(x) ≤0, correspond to the points where the graph is below the x-axis, so the values of x for which f(x) ≤0 are (−3,−0.5].

The relative maxima or minima are the x-coordinate points where the continuous function has a turning point, like x=3 which is a relative maximum point

.

There are no relative minimum points for the given function.

The value of x for f(x)=3 is the x- coordinate of the point of intersection of the graph with the horizontal line y=3

So, x≈3.

we will determine the  y = coordinate of the point of intersection of the graph with the vertical line

x=0, which is above 2, so f(0) is positive.

Therefore, the domain of the function is interval (−3,6], and the range of the function is interval (−6,3].

Answer:

Step-by-step explanation: I think the answer would be B or D they seem the most logical

a) The graph will have a "V" shape, which opens upwards.

b) The horizontal shift of 1 unit to the left.

c) The vertical shift is of 5 units downwards.

Here we have the absolute value function:

f(x) = |x + 1| - 5

First we want to describe the graph shape, we know that it is an absolute value function, so it will have a "V" shape.

The arms will make an angle of 45° with the vertical and horizontal (because the slope is 1)

And it will open upwards, because the slope is positive.

Now, remember that if the parent function is:

f(x).

A translation is written as:

g(x) = f(x + a) + b

Where a is the horizontal translation and b is the vertical translation, such that:

In this case we have:

f(x) = |x + 1| - 5

So this is a translation of 1 unit to the left and 5 units down of the parent absolute value function.

b) The horizontal shift of 1 unit to the left.

c) The vertical shift is of 5 units downwards.

[–3, 6) ∪ (6, ∞)

Step-by-step explanation:

f(x) = 1/(x - 3)

the domain is every value of x that does not turn the denominator to 0. so, x <> 3.

g(x) = sqrt(x + 3)

the domain is every value of x that does not turn (x+3) into a negative value. so, x >= -3.

f(g(x)) = 1/(sqrt(x + 3) - 3)

the domain is all values of x that are valid for g(x) AND that do not generate range values of g(x) that violate the domain of f(x).

so, it is (x >= -3) AND (sqrt(x + 3) <> 3).

and sqrt(x + 3) = 3, if (x + 3) = 9.

that means x = 6.

so, 6 is forbidden, every other value of x is allowed here.

therefore, the domain of f(g(x)) is

(x >= -3) AND (x <> 6)

and that is equivalent to

[-3, 6) u (6, infinity)

everything larger or equal to -3 and different from 6.
