Answer:

Line AC

Step-by-step explanation:

Given

See attachment for triangles

Required

60 degrees clockwise rotation about A

Since [tex]\triangle ABC[/tex] and [tex]\triangle ABD[/tex] are equilateral, then all angles in both triangles are [tex]60^o[/tex]

So, rotating in clockwise direction of A means that a line segment in the right of A will be considered.

The closest is line AC;

Hence, AC is [tex]60^o[/tex] clockwise of point A

Answer:

h(4) = 0

Step-by-step explanation:

Hoping its ' kx '

[tex]h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k[/tex]

Now we have k = -2. We will find h(4).

[tex]h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0[/tex]

Answer:

h(4) = 0

Step-by-step explanation:

GIVEN :-

TO FIND :-

SOLUTION :-

To find the value of h(4) , you need to find 'k' first by using the given facts.

[tex]h(-1) = (-1)^2 + k(-1) - 8 = -5[/tex]

[tex]=> 1 - k - 8 = -5[/tex]

[tex]=> -k - 7 = -5[/tex]

[tex]=> -k - 7 + 7 = -5 + 7[/tex]

[tex]=> -k = 2[/tex]

[tex]=> -k(-1) = 2(-1)[/tex]

[tex]=> k = -2[/tex]

Putting the value of k,

[tex]h(4) = (4)^2 + (-2)(4) - 8[/tex]

       [tex]= 16 - 8 - 8[/tex]

       [tex]= 16 - 16[/tex]

       [tex]= 0[/tex]

Step-by-step explanation:

Given:

In triangle ABC, AB = AC, AD is angle bisector and measure of angle C is 49 degrees.

To find:

The value of x and y.

Solution:

In triangle ABC,

[tex]AB=AC[/tex]                    (Given)

So, triangle ABC is an isosceles triangle and by the definition of base angles the base angles of isosceles triangle are congruent.

In isosceles triangle ABC,

[tex]\angle B\cong \angle C[/tex]

[tex]m\angle B\cong m\angle C[/tex]

[tex]m\angle B\cong 49^\circ[/tex]

The angle bisector of an isosceles triangle is the median and altitude of the triangle. So, the angle bisector is perpendicular to the base.

[tex]m\angle ADB=90^\circ[/tex]

[tex]x^\circ=90^\circ[/tex]

In triangle ABD,

[tex]m\angle DAB+m\angle ABD+m\angle ADB=180^\circ[/tex]         [Angle sum property]

[tex]y^\circ+49^\circ+x^\circ=180^\circ[/tex]

[tex]y^\circ+49^\circ+90^\circ=180^\circ[/tex]

[tex]y^\circ=180^\circ-49^\circ-90^\circ[/tex]

[tex]y^\circ=41^\circ[/tex]

Therefore, the correct option is B.

Answer:

Step-by-step explanation:

Part C: (Explanation with steps)

Let the length of the swimming pool = l feet

And width of the pool = w feet

Perimeter of the pool = 2(l + w) feet

Since, perimeter of the pool = 8 feet

2(l + w) = 80

l + w = 40

l = (80 - w) -------(1)

Area of the pool = Length × width

A(w) = l × w

By substituting the value of l from equation (1)

A(w) = (80 - w) × w

A(w) = 80w - w²

To find the maximum area of the pool we will find the derivative of the function with respect to 'w' and equate it to zero.

A'(w) = 80 - 2w

(80 - 2w) = 0

w = [tex]\frac{80}{2}[/tex]

w = 40 feet

Therefore, for width (w) = 40 feet area of the pool will be maximum.

From equation (1),

l = 80 - 40

l = 40 feet

Therefore, maximum area of the pool = l × w

                                                               = 40 × 40

                                                               = 1600 square feet

Part A:

Function representing area of the pool,

A(w) = -w² + 80w

Part B:

Maximum area of the surface of the pool = 1600 square feet

Answer:

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

Answer:

C.

Step-by-step explanation:

15^2 not = 6^2 + 11^2.

Answer:

Step-by-step explanation:

Corresponding angles are congruent

x² - 72 = 6x

x² - 6x - 72 = 0

Sum = -6

Product = -72

Factor = -12 , 6   {-12*6 = -72  & -12 +6 = -6}

x² + 6x - 12x -72 = 0

x(x + 6) - 12(x + 6) = 0

(x + 6)(x -12)=0   {Ignore x + 6 = 0 because angles won't be in negative}

x - 12 = 0

x = 12

Step-by-step explanation:

Correct option is

A

x= 4 and y = 5

Let the parallelogram be ABCD Perimeter= 40cm

AB =3x cm BC=2x cm(given)

Perimeter of parallelogram 2(3x+2x)=40

solving equation we get x=4

Also,AB=CD(opposite sides of parallelogram) 3x=2(y+1) (given)

Putting x=4

3(4)=2y+2

12=2y+2

10=2y

Hence y=5 and x=4

Answer:

a = 9 / 7

step by step explanation:

9 / - a + 15 = 8

Determined the defined range

9 / ( - a ) + 15 = 8 , a ≠ 0

subtract 15 from each side

9 / - a + 15 - 15 = 8 - 15

calculate the difference

9 / - a = - 7

multiply both side of equation by - a

9 / - a × - a = - 7 × - a

9 = 7 a

divide each side by of equation by -7

9 / 7 = 7 a / 7

9 / 7 = a

swap the side of equation . ( optional )

a = 9 / 7

Assuming DF is a straight line,

Given E is the mid-point of DF

mCE = mGF

CE || GF

Then

mDE = mEF (E midpoint of DF)

Angle DEC = Angle EFG (corresponding angle, DF transversal of parallel lines CE and GF)

mCE = mGF (given)

Then triangles DCE and EGF are congruent by reason SAS (side-angle-side)

Answer:

IDR 3,651.04

Step-by-step explanation:

4x24=96

96x2,400=230,400

230,400+50,000=280,400

280,400x1.25=350,500

350,500/96=3,651.04

IDR 3,651.04

Answer:

3651 IDR

Step-by-step explanation:

I need to make some assumptions, as the problem description is sometimes too vague.

I assume the delivery charge to cover all 4 boxes as one lump sum.

4 boxes with 24 pouches each.

=> Roma has 96 pouches total.

each pouch cost 2400. that is in total

96×2400 = 230400 IDR

then there is the delivery charge of 50000 for everything.

so, the total costs for Roma are

230400 + 50000 = 280400 IDR

25% profit means that the total sales (assuming all pouches are sold) is 25% higher than the costs.

profit = 280400 + 25%

25% is 1/4 of the total (as 25%×4 = 100%).

25% = 280400 / 4 = 70100.

so, in order to make 25% profit the total sales price (for all pouches sold) has to be

280400 + 70100 = 350500 IDR

now, we have 96 pouches. after selling all 96 pouches we need to have an income of 350500 IDR.

the price for each pouch has to be an equal share of the 350500.

pouch price = 350500 / 96 = 3651 IDR.
