Answer:

(i) and (iii)

Step-by-step explanation:

for i)

f(x) = [tex]\frac{x^{2}-4}{x+2}[/tex]

     =[tex]\frac{(x+2)(x-2)}{x+2}[/tex]

     =(x-2)

As x =-2

f(x)=-2-2

f(x)=-4

so it is a continuous function

for ii)

from the result of (i) we can deduce the result of second and we see that it is not equal to zero so it is not a continuous function

iii)

f(x)=[tex]\frac{x^{2}+4x+4}{x+2}[/tex]

f(x)=[tex]\frac{(x+2)^{2}}{x+2}[/tex]

f(x)=[tex]\frac{(x+2)(x+2)}{x+2}[/tex]

f(x)=x+2

as x= -2

f(x)=-2+2

f(x)=0

so it is a continuous function

iv) From the result of iii we can deduct that

f(x)=0 because it have the same equation so it is not a continuous function

Answer:

Answer:

x - 1 and x + 2

Step-by-step explanation:

By the factor theorem if (x - a) is a factor then f(a) = 0.

Try x - 1:_

f(1) =  5(1)^3 + 8(1)^2 - 7 - 6

= 5 + 8 - 7 - 7

= 0  so x - 1 is a factor

We can find the other factors by long division:-

            5x^2  + 13x + 6

           -----------------------------------

x - 1 )    5x^3  + 8x^2  -  7x  -  6

           5x^3  -   5x^2

          --------------------

                        13x^2  -   7x

                         13x^2  -  13x

                         ------------------

                                       6x - 6

                                        6x - 6

                          -----------------

    5x^2  + 13x + 6   = (5x + 3)(x + 2)                          

Answer:

It would be 2/13 because imagine being given 4 decks of 13 cards and you have. Higher chance of having one to two of an ace or king in the deck compared to pulling none to all four. So 2/13 due to the ratio of 13

If a, b and c are the lengths of a right triangle and c is the longest side, then:

[tex]a^2+b^2=c^2[/tex]

We have a = 18cm, b = 24cm and c = 30cm. Substitute and check:

[tex]L_s=18^2+24^2=324+576=900\\\\R_s=30^2=900\\\\L_s=R_s[/tex]

The triangle with side lengths of 18cm, 24cm, and 30cm is a right triangle and this can be determined by using the Pythagorean theorem.

Given :

The triangle with side lengths of 18cm, 24cm, and 30 cm.

The following steps can be used to determine the given triangle is a right triangle or not:

Step 1 - The Pythagorean theorem can be used to determine whether the given triangle is a right triangle or not.

Step 2 - According to the Pythagorean theorem, the sum of the square of the two shorter sides of the triangle is equal to the square of the larger side of the triangle that is:

[tex]\rm H^2 = P^2+B^2[/tex]

where H is the hypotenuse, P is the perpendicular, and B is the base of the right angle triangle.

Step 3 - To determine the given triangle is a right angle triangle, the Pythagorean theorem must be satisfied.

[tex]24^2 + 18^2 = 30^2[/tex]

LHS = [tex]24^2+18^2[/tex]

       = 576 + 324

       = 900

RHS = [tex]30^2[/tex]

       = 900

So, LHS is equal to RHS. Therefore, the given triangle is a right angle triangle.

Answer:

vw = r      This is not correct

abs ( c - 450) <= 45

Step-by-step explanation:

1.  v = wr

Divide by w             Divide by wr            Divide by r

v/w = wr/w =r            v/wr = wr/wr =1         v/r = wr/r =w

vw = r      This is not correct

v/w = r    This one is good

v/wr = 1       This one is good

v/r= w    This one is good

2.  When working with absolute values, the amount that can vary is on the other side from the absolute value.  

abs( value - target)  inequality  amount that it varies by

the target is 450

no more than is less than or equal to

the amount we can vary by is 45

abs ( c - 450) <= 45

1. The first offered choice is equivalent to ...

... v = r/w . . . . . divide both sides by w

which is not the same as v = wr.

C) Symmetric

Step-by-step explanation:

The symmetric property is the idea that if A = B, then B = A. Flipping the equation around doesn't matter.

It's like saying 2+3 = 5 is the same as 5 = 2+3. We can extend the symmetric property to not only deal with equations, but include congruence statements as well.

Answer:

A' (0, -1)

B' (0, 1)

C' (4, 1)

D' (4, -1)

Step-by-step explanation:

We have the following points of a quadrilateral ABCD:

A(−2, 2), B(−2, 4), C(2, 4), and D(2, 2)

and the rule of the translation is given by:

(x, y) ---> (x + 2, y − 3)

which means that each point will move means  3 units to the left and 4 units upwards.

So the points after transformation will be:

A(−2, 2) ---> (-2+2, 2-3) ---> A' (0, -1)

B(−2, 4) ---> (-2+2, 4-3) ---> B' (0, 1)

C(2, 4) ---> (2+2, 4-3) ---> C' (4, 1)

D(2, 2) ---> (2+2, 2-3) ---> D' (4, -1)

If we plot these points on a graph and join the corresponding vertices with line segments, then we will see that all the the lines will be parallel to each other since they followed the same rule of transformation.

The new coordinates of the transformed vertices A', B', C', and D' are:

A' (0, -1)

B' (0, 1)

C' (4, 1)

D' (4, -1)

To find the new coordinates of the transformed vertices A', B', C', and D', you need to apply the transformation rule (x + 2, y - 3) to the original coordinates of A, B, C, and D.

A' = (x + 2, y - 3)

A' = (-2 + 2, 2 - 3)

A' = (0, -1)

B' = (x + 2, y - 3)

B' = (-2 + 2, 4 - 3)

B' = (0, 1)

C' = (x + 2, y - 3)

C' = (2 + 2, 4 - 3)

C' = (4, 1)

D' = (x + 2, y - 3)

D' = (2 + 2, 2 - 3)

D' = (4, -1)

So, the new coordinates of the transformed vertices A', B', C', and D' are:

A' (0, -1)

B' (0, 1)

C' (4, 1)

D' (4, -1)

Now, let's describe the characteristics of the quadrilateral ABCD and its image A'B'C'D' when the corresponding vertices are connected with line segments:

Quadrilateral ABCD:

A(−2, 2), B(−2, 4), C(2, 4), and D(2, 2)

ABCD is a trapezoid with two parallel sides (AB and CD) and two non-parallel sides (BC and AD).

The trapezoid is located in the first quadrant.

Image A'B'C'D':

A'(0, -1), B'(0, 1), C'(4, 1), and D'(4, -1)

A'B'C'D' is also a trapezoid with two parallel sides (A'B' and C'D') and two non-parallel sides (B'C' and A'D').

A'B'C'D' is located in a different position due to the transformation. It has been shifted 2 units to the right and 3 units down.

The transformation (x + 2, y - 3) has effectively shifted the entire quadrilateral 2 units to the right and 3 units down in the coordinate plane. The basic shape and characteristics of the trapezoid are preserved, but its position in the plane has changed.

The given radius is = 60 feet

The volume of the sphere is given by = [tex]\frac{4}{3} \pi r^{3}[/tex]

So we will find the volume of the sphere using radius as 60 and pi as 3.14

Volume = [tex]\frac{4}{3}*3.14*60*60*60[/tex] = 902059.20 cubic feet

As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.

So volume of quarter sphere = [tex]\frac{902059.20}{4}[/tex]

= 225514.80 cubic feet

And rounding this to nearest whole number we get 225515 cubic feet as the answer.

Option no C 600 minutes

Step-by-step explanation:

Given:

gallons of pool = 24000 gallon

Rate at which it is filled = 40 gallons per minute

To find :

Time taken to fill the pool=?

Solution:

We know that rate is the time in which a thing is being done at per minute or per hour or per second. In our question it is given that the rate is 40 gallons per minute which means that 40 gallons are filled in one minute

Now

In one minute = 40 gallons filled

Total pool size = 24000 gallons

Total time taken = [tex]\frac{Total pool size}{gallon filled in one minute}[/tex]

Putting in the values

Total time taken = [tex]\frac{24000}{40}[/tex]

Total time taken = 600 minutes

So the answer is option c which is 600 minutes

 = (-16+10)/(10-4)

  = -6/6

= -1

The slope is -1

Lily swam a 100-meter race, completing the first half in 27.8 seconds and the second half in 30.12 seconds. The difference between these times reveals that it took Lily about 2.32 seconds longer to swim the second half of the race compared to the first half.

The student, Lily, swam a 100-meter race with the first and second halves timed separately. She completed the first half in 27.8 seconds and the second half in 30.12 seconds. To find out how much longer it took her to swim the second half than the first, we need to subtract the first time from the second.

So, the calculation would be: 30.12 seconds (second half) - 27.8 seconds (first half) = 2.32 seconds. Therefore, it took Lily about 2.32 seconds longer to swim the second half of the race compared to the first half.
