The required domain of the function given is all real numbers. Option B is correct.

Given that,
To determine the domain of the given function shown in the graph.

The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.

Here,
As shown in the graph function is given as y = 1.5,
So the domain x for the given function is given as all real values of the x from -∞ to +∞.

Thus, the required domain of the function given is all real numbers. Option B is correct.

Answer:

D. X = -5

Step-by-step explanation:

With f(x) = -5x + 4, all you have to do is plug in X for the x in the problem so you would do "f(x) = -5 x 5 + 4" (Becuase X=5 for d) Then you get the answer 29.

Answer:

x = 1.4

Step-by-step explanation:

6 - 2x = 8(x -1)

6 - 2x = 8x - 8

collecting like terms

-2x - 8x = -8 - 6

-10x = -14

10x = 14

dividing both sides by 10

x = 14/10

x = 1.40 (2d.p)

Answer:

675 samples

752 samples

Step-by-step explanation:

Given that :

α = 90%

E = 0.03

Previous estimate (p) = 0.34

Estimated sample proportion (n)

n = p *q * (Zcritical /E)

Zcritical = α/2 = (1 - 0.9) /2 = 0.1 / 2 = 0.05

Z0.05 = 1.645 ( Z probability calculator)

q = 1 - p = 1 - 0.34 = 0.66

n = 0.34 * 0.66 * (1.645/0.03)^2

n = 674.70

n = 675

B.) without prior estimate given ;

p and q should have equal probability

Hence ;

p = 0.5 ; q = 0.5

n = 0.5 * 0.5 * (1.645/0.03)^2

n = 751.67361

n = 752

Step-by-step explanation:

The all horizontal and vertical intercepts of the graph are x-intercept(s): (-4/3, 0), (1,0), (3,0) and y-intercept(s): (0,72).

The given function is g(x) = -2(3x+4)(x-1)(x-3)².

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

1) The sketch a graph of the polynomial is given below.

2) To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

x-intercept(s):

(-4/3, 0), (1,0), (3,0)

y-intercept(s): (0,72)

3) Use the degree and the leading coefficient to determine the behavior.

Falls to the left and falls to the right

Therefore, the all horizontal and vertical intercepts of the graph are x-intercept(s): (-4/3, 0), (1,0), (3,0) and y-intercept(s): (0,72).

Answer:

Lincoln Avenue is represented by the line [tex] x = 5 [/tex], which is a VERTICAL LINE.

Step-by-step explanation:

The equation of the line of Washington Avenue, x = 3, suggests that the line is a vertical line, since a vertical line takes the form of x = k, where k is the value x would always take and also it is the x-intercept.

Given that Lincoln Avenue passes through the point (5, 2), and its line is parallel to that of Washington Avenue, it means that the line do not intercept each other, and Lincoln Avenue is also a vertical line.

Therefore, if Lincoln Avenue passes through (5, 2), its line can be represented also in the form, x = k. Where, k is the value that x would always take, and also, it is the x-intercept. x would always be 5 even when y changes.

Therefore, the equation of the line that represents Lincoln Avenue would be:

✅ [tex] x = 5 [/tex]

✅This is also a Vertical line.

The sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have to determine the sum of the two algebraic expressions modeled by the algebra tiles.

Let the variable would be x.

List the algebraic expression by the algebra modeling tiles

⇒ (2x - 6) + (x +5)

⇒ 2x - 6 + x +5

Rearrange the terms and apply the arithmetic operation

⇒ 3x - 1

Therefore, the sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.

Answer:

2578

Step-by-step explanation:

Answer:

First you need to divide 1.6 by 2 to get .8 then multiply

.8 x 6 = 4.8

.8 x 8 = 6.4

Then multiply 4.8 by 6.4 and get 30.72

The area of the actual backyard is 30.72 [tex]m^2[/tex]

Since A scale model drawing of a backyard is 6 centimeters wide and 8 centimeters long. The scale model uses a scale in which 2 centimeters represents 1.6 meters.

Here we were required to divide 1.6 by 2 so that 0.8 could come

Now

[tex]= (.8 \times 6) \times (.8 \times 8) \\\\= 4.8 \times 6.4[/tex]

= 30.72

Therefore, The area of the actual backyard is 30.72 [tex]m^2[/tex]

We verified that the equation [tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex] has both sides equal.

Step-by-step explanation:

We need to solve and verify: [tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex]

Solving:

[tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex]

Converting into improper fractions

[tex]\frac{15}{2}\div\frac{3}{2}=5[/tex]

Converting division sign into multiplication and reversing 3/2 i.e

[tex]\frac{15}{2}\times\frac{2}{3}=5[/tex]

Now simplifying

[tex]\frac{15}{3}=5 \\5=5[/tex]

So, We verified that the equation [tex]7\frac{1}{2}\div1\frac{1}{2}=5[/tex] has both sides equal.
