The domain of the function graphed is $x$ . Option (a) is correct.

Further explanation:

Domain is a set of all the possible values of the function. The value at which the function is defined is known as domain.

Range is a set of values that the function takes.

The output values of the function are known as range and the input values on which function is defined is known as the domain of the function.

Explanation:

The function can’t take the values greater than 7 or equal to 7.

The function is defined for the values of x less than 7. Therefore the domain of the function is $x$ .

The domain of the function graphed is $x$ . Option (a) is correct.

Option (a) is correct as the domain of the graphed function is $x$ .

Option (b) is not correct as the domain of the graphed function is $x$ .

Option (c) is not correct as the domain of the graphed function is $x$ .

Option (d) is not correct as the domain of the graphed function is $x$ .

The function is defined over these ranges of x:
(-∞, -1) and [-1, 7), that is for x < 7.

Note that
The function is undefined at x = --1 over the left portion of the straight line, but the function s defined at x = -1 for the right portion f the straight line.
The function is undefined at x = 7 and for larger values of x.

Answer: x < 7

200 students attend a school which offers French and History. 10% of those who take History also take French and 4 times as many

SIZIF [17.4K]

Answer: P(hist& french)=16/200=0.08

Step-by-step explanation:

To find the required probability we have to know what is the number of students that take both History and French ( Intersection of 2 circles in Venn diagram)

1. Lets find the number of students that take History or French or both.

We know that 8% from 200 take neither History or French. So number or students who take History or French or both is 200-200*0.08=184

2. Let number of students that takes French (or both Fr+Hist)=x (left circle)

So number of students that takes History (or both Fr+Hist)=4x (right circle)

So number of students that take both French+History= 10% from 4x or

0.1*4x=0.4x (circles' intersection)

3. Now we have the equation as follows:

x+4*x-0.4*x = 184

4.6*x=184

x=40 students takes French (or both French+ History)

4*x= 40*4=160 students takes History (or both French+ History)

10% from 160 =0.1*160=16 students takes both History and French

P(hist& french)=16/200=0.08

Arrange the circles (represented by their equations in general form) in ascending order of their radius lengths. Tiles x2 + y2 −

sashaice [31]

When doing this, we would have to first straight them all out, and as we see above, they are just all over the place, and then, we would have to set them up as a sequence.

$\left[\begin{array}{ccc}5x2 + 5y2 - 20x + 30y + 40 = 0\end{array}\right]$ would be our first step in this problem mainly because it contains the most terms in this aspect.

Then we would then $x2 + y2 - 2x + 2y -1 = 0$ , then, $2x2 + 2y2 - 28x - 32y - 8 = 0$ .

These would only be our first 3 part of the sequence in this aspect.

The others would then be the following:

$\boxed{x2 + y2 + 12x - 2y - 9 = 0 } \ then \ , \boxed{x2 + y2 - 4x + 4y - 10 = 0} \\ \\ then \ \boxed{x2 + y2 - 8x - 6y -20 = 0}$

Thus, as we would have one more afterward, our last part of the sequence would then be the following.

$\boxed{\boxed{4x2 + 4y2 + 16x + 24y - 40 = 0}}$

I hope this was found helpful!

Rob is making a scale model of the Solar System on the school field. He wants the distance from the Sun to Jupiter to be 8 metre

ANEK [815]

Answer:

1 : 9.75 * 10⁷

Step-by-step explanation:

To find n, we have to divide the real distance by the scale distance. This is 7.8 * 10⁸ / 8 = 0.975 * 10⁸ = 9.75 * 10⁷ which means that the ratio is 1 : 9.75 * 10⁷.

To make the same totem pole with wood that costs y dollars Ronald would have to spend a total of $35.19. Explain which property

nikitadnepr [17]

Answer:

Part 1) Subtraction Property of Equality

Part 2) This property can be used , because addition and subtraction have inverse relationships

Step-by-step explanation:

we know that

The subtraction property of equality tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same

we have

$10.50+y=35.19$

Solve for y

Applying Subtraction Property of Equality

subtract 10.50 both sides

$10.50+y-10.50=35.19-10.50$

$y=\$24.69$

Remember that this property can be used , because addition and subtraction have inverse relationships.
