Find the volume of the cylinder.

r = 5 cm

h = 9 cm

Answer:

y=8x-26

y=-1/8x-13/8

Step-by-step explanation:

Y=kx+b

When the two lines are parallel,

k1=k2

k2=8 And passes through the point (3, -2)

So y+2=8(x-3)

Get the answer y=8x-26

When the two lines are perpendicular,

k1*k2=-1

K2=-1/8 And passes through the point (3,-2)

So y+2=-1/8（x-3）

Get the answer y=-1/8x-13/8

Answer:

3540

2

Step-by-step explanation:

Total number of members = 60

Number of members to be elected = 2

Since the order of selection matters as the first is president and second is vice president ;

Using the permutation formula :

nPr = n! ÷ (n-r)!

60P2 = 60! ÷ (60 - 2)!

60P2 = 60! ÷ 58!

60P2 = 3540

B.) 2 members A and B will accept to serve only if they are selected to serve together ;

Since only 2 members (president and vice president) are to be chosen ; Hence, only the tow of them (A and B) will be chosen, to do this ;

2P2 = 2! /(2 - 2)! = 2! / 0! = (2*1)/1 = 2

Answer:

2700 I think?

Step-by-step explanation:

Um 3/ 1/4 = 12 and 3 3/4 / 1/4 = 15 so 15 * 12 * 15 is 2700

2x - 4 = 1

2x = 1 + 4

2x = 5

x = 5/2

Step-by-step explanation:

Coplanar points: A group of points that lie in the same plane are coplanar. Any two or three points are always coplanar. Four or more points might or might not be coplanar. The left side of the above figure shows coplanar points A, B, C, and D.

Since the denominators are unequal, we find the L.C.M (lowest common multiple) for both denominators.

The L. C. M for 7 and 8 is 56.

Now,

Answer:

ans: x> -9

Step-by-step explanation:

if you multiply

-2x < 18 by -1 than inequality sign changes as

2x > -18

divide both side by 2 to free 2x to x i.e

2x/2 > (-18/2)

so

x> -9

Answer:

no

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 18, and 18² = 324

11² + 16² = 121 + 256 = 377 ≠ 324

Then triangle is not right.

Answer:

(a) (0.9240,  0.956)

(b) (0.6383, 0.7017)

Step-by-step explanation:

The number of internet users involved in the survey, n = 846

The percentage of the respondents that said the internet has been good thing for them personally, [tex]\hat p[/tex] = 94%

(a) The confidence interval of a percentage is given as follows;

[tex]CI=\hat{p}\pm z\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

The z-value for 95% confidence interval = 1.96

We get;

[tex]CI=0.94\pm 1.96\times \sqrt{\dfrac{0.94 \times (1-0.94)}{846}} \approx 0.94 \pm 1.6003 \times 10^{-2}[/tex]

CI = 0.9240 ≤ [tex]\hat p[/tex] ≤ 0.956 = (0.9240,  0.956)

(b) The percentage of the internet users that said the internet has directly strengthened their relationship with their families, [tex]\hat p[/tex] = 67% = 0.67

The 95% confidence interval is therefore;

[tex]CI=0.67\pm 1.96\times \sqrt{\dfrac{0.67 \times (1-0.67)}{846}} \approx 0.67 \pm 3.1686\times 10^{-2}[/tex]

From which we have;

CI = 0.6383 ≤ [tex]\hat p[/tex] ≤ 0.7017 = (0.6383, 0.7017)

Answer:

x=2

Step-by-step explanation:

15x-10=20

+10 to both sides

15x=30

divide both sides by 15

x=2

Answer:

x = 2

Step-by-step explanation:

15 x - 10 = 20

15 times 2 = 30

30 -10 = 20

20 = 20

So x equals 2

Answer:

3x-8

Step-by-step explanation:

9x²-64  is the same as

(3x)² - 8²

now we have the difference of 2 squares, a²-b² =(a -b)(a +b), where a=3x, b=8

9x²-64 =  (3x-8)(3x+8)

Step-by-step explanation:

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".

Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.

Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3

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

To summarize so far, we have these three facts

in this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.

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

Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.

It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).

Answer:

x=2

Step-by-step explanation:

the minimum value of y is when x = 2.

Answer:

The minimum is at x = -2

Step-by-step explanation:

f(x) = (x+2)^2 -3

This is in vertex form

f(x) = ( x-h)^2 +k  where (h,k) is the vertex

Since this is an  upwards  opening  parabola the vertex is the minimum

f(x) = (x- -2)^2 -3

The vertex is (-2,-3)

The minimum is at x = -2
