If I had 4 eggs
A thief gives me 3 eggs
My farm rooster lays 5 eggs
How many eggs do I have?
Answer:
You have 3 eggs.
Step-by-step explanation:
You "had" 4 eggs, those do not count. A thief then gave you 3 eggs. And lastly, a rooster does not lay eggs. In conclusion, you have 3 eggs.
The total number of eggs he finally has as inferred from the riddle is 3 eggs.
Evaluating each sentence :
If I had 4 eggs ; This is an imagination, hence, the speaker was only imagining if he had. Hence, total here is 0
A thief gave out 3 eggs ; Hence, the total number of eggs = (0 + 3) = 3 eggs
Farm Rooster laying 5 eggs is impossible S Farm roosters do not lay eggs. Number of eggs here is 0.
Hence, the total number of eggs = (0 + 3 + 0) = 3 eggs.

4. An isosceles triangle has sides that measure 7cm and 15cm. Find the third side of the
triangle, then find the perimeter.
Answer:
Third side is 15cm. Perimeter is 37cm.
Step-by-step explanation:
In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.
So if the third side is 7cm
7+7=14cm which is less than 15 cm.
hence third side is 15 cm as
15+15=30cm which is greater than 7cm
15+7=22cm which is greater than 12cm
then
perimeter=15+7+15=37cm

A rectangular building with a square front is to be constructed of materials that costs 11 dollars per ft2 for the flat roof, 14 dollars per ft2 for the sides and the back, and 15 dollars per ft2 for the glass front. We will ignore the bottom of the building. If the volume of the building is 5,600 ft3, what dimensions will minimize the cost of materials? (Round your answers to the nearest hundreth such that the dimensions increase from the smallest to the largest.)
Answer:
y = 23.14 ft
x = 15.56 ft
so the dimensions of the building will be = 15.56 ft x 15.56 ft x 23.14 ft
Step-by-step explanation:
the area of the roof = xy
cost of the roof = 11xy
the area of the sides and back = 2xy + x²
cost of the sides and back = 14(2xy + x²) = 28xy + 14x²
area of the glass front = x²
cost of the glass front = 15x²
minimize:
total cost = 11xy + 28xy + 14x² + 15x² = 39xy + 29x²
total volume = x²y = 5600 ⇒ constraint
39y + 58x = 2λxy
39x = λx2
x²y = 5600
λx = 39 which we replace into the first equation
39y + 58x = 78y
58x = 39y
(58x)²y = 58² · 5600
now we replace 58x by 39y
(39y)²y = 58² · 5600
39² · y³ = 58² · 5600
y³ = (58² · 5600) / 39² = 12,385.53583
y = ∛12,385.53583 = 23.14 ft
x² = 5600/ 23.14 = 242.04
x = 15.56 ft

What are similar triangles?
Two triangles are said to be similar if their sides are proportional and their angles are equal.
Given data ,
The two triangles are ΔABC and ΔDFG are similar
Length of AB = 5 inches
Length of BC = 6 inches
Length of AC = 7 inches
Length of DF = 15 inches
Length of FG = 18 inches
And , ∠B is congruent to ∠F
The two triangles are similar , so the ratio of
AB / DF = BC / FG = AC / DG
Therefore , 5 / 15 = 7 / DG
DG = 21 inches
Hence , the proportion used to find the value of DG is 15 x 7 = 5 x DG

a. 3/6.
b. 1/3.
c. 1/2.
d. 1/6.
Answer:
The option that are correct is option a and option c

From the question we are told that
The sample space is n = 6 (i.e six sides)
The number of even numbers in the sample space is k = 3 (i.e 2,4, 6)
Generally the probability of rolling an even number with a six-sided, equally weighted die is mathematically represented as

The function f given by f(x)=3x5−4x3−3x has a relative maximum at x?
Answer:
We have the function:
f(x) = 3*x^5 - 4*x^3 - 3*x
To find the maximum/minimums, we first need to look at the roots of the first derivative of f(x), this is:
f´(x) = 5*3*x^4 - 3*4*x^2 - 3
f´(x) = 15*x^4 - 12*x^2 - 3
We can do the change of variable:
u = x^2
Then we can rewrite:
f'(u) = 15*u^2 - 12*u - 3
This is a quadratic equation, the solutions will be obtained by the Bhaskara´s equation:
So the solutions are:
[tex]u = \frac{+12 +- \sqrt{(-12)^2 - 4*(-3)*15} }{2*15} = \frac{12 +- 18}{30}[/tex]
Then the two solutions are:
u = (12 + 18)/30 = 1
this leads to:
x^2 = 1, then we can have x = ± 1
the other solution is:
u = (12 - 18)/30 = -6/30 = -(1/5)
and x^2 = -(1/5), then:
x = ±√(1/5)*i
So those are the possible values for the minimum/maximums.
Now to see it, we need to look at the second derivative ad see iff:
f´´(x) > 0 then x is a minimum
f''(x) < 0, then x is a maximum.
We have that:
f´´(x) = 4*15*x^3 - 2*12*x
f´´(x) = 60*x^3 - 24*x
Notice that the two complex roots will lead to complex values of f(x), so these can be ignored here, then we have to try only with x = ± 1.
f´´(1) = 60*1^3 - 24*1 = 36
then x = 1 is a minimum.
f´´(-1) = 60*(-1)^3 -24*-1 = -36
then x = -1 is a maximum.
Then we can conclude that the relative maximum is at x = -1
The function f given by [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at
x = -1
The given function is:
[tex]f(x) = 3x^5-4x^3-3x[/tex]
Find the derivative of the function:
[tex]f'(x)=15x^4-12x^2-3[/tex]
Find the critical points by equation f'(x) to zero
[tex]15x^4-12x^2-3=0\\\\5x^4-4x^2-1=0[/tex]
By solving the equation above, the critical points are:
x = -1, x = 1
Find the second derivative of f(x)
[tex]f''(x)=60x^3-24x[/tex]
[tex]f''(-1)=60(-1)^3-24(-1)\\\\f''(-1)=-36[/tex]
Since f''(-1) < 0, x = -1 is a maximum point
[tex]f''(1)=60(1)^3-24(1)\\\\f''(1)=36[/tex]
Since f''(1) > 0, x = 1 is a minimum point
Therefore, the function [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at x = -1
