Answer:
-16x
Step-by-step explanation:
6x + ? = -10x
Subtract 6x from each side
6x + ? -6x= -10x-6x
? = -16x
Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)?
Help
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 :-
A quadratic function h(x) = x² + kx - 8h(-1) = -5TO FIND :-
Value of h(4)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]
Add both the sides by 7.[tex]=> -k - 7 + 7 = -5 + 7[/tex]
[tex]=> -k = 2[/tex]
Multiply both the sides by -1.[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]

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

What is the surface area of the triangular prism?
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:

when
[tex] {x}^{3} + a {x}^{2} + 5x + 3[/tex]

[tex]x + 2[/tex]
the remainder is b. Determine the value of 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

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.

Find the value of x. Round to the nearest tenth.
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)

9514 1404 393
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
