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:

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:

9 x 24 x 1/2(basically dividing by 2) = 108 , 108  x 2(two triangles) = 216

40 x 15 = 600, 600 x 2(two slanted rectangles) = 1200

40 x 24 = 960 (area of base)

Add given areas:

216 + 1,200 + 960 = 2,376 square feet, B.

Answer:

(B) 2,376

Step-by-step explanation:

I was the first person to actually answer since the other person used you for points but it is B

x³ + ax² + 5x + 3. x + 2 = 0

x = -2

(-2)³ + a(-2)² + 5(-2) + 3 = 0

-8 + 4a - 10 + 3 = 0

4a - 15 = 0

4a = 15

a = 15/4

Answer:

D or y-25=2(x-10)

Step-by-step explanation:

If you graph all or the answers the only one that hits both points is D.

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:

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.

P(C) = 4/10 = 2/5

P(A) = 6/10 = 3/5

Answer:

10.

Step-by-step explanation:

According to Pythagoras,

14^2 = 10^2 + x^2

196 = 100 + x^2

x^2 = 196-100

x^2 = 96

x = 9.8

x = 10  (nearest tenth)

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:

  C)  7

Step-by-step explanation:

We have ...

  TS +SR = 19

  SR +RQ = 13

Adding these two equations together, we have ...

  TS +2·SR +RQ = 19 +13 = 32

We also have ...

  TS +SR +RQ = 25

Subtracting this from the equation above, we have ...

  (TS +2·SR +RQ) -(TS +SR +RQ) = 32 -25

  SR = 7
