The car seat appropriate for a child 33-lb will be shown by the inequality 25 < Child seat < 75. The inequality for a child up to and including 26 lb will be written as Child ≤ 26.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given that a family is comparing different car seats. One car seat is designed for a child up to and including 26 lb. Another car seat is designed for a child between 18 lb and 40 lb. A third car seat is designed for a child between 25 lb and 75 lb.
A car seat appropriate for a 33-lb child will come under the seat which is designed for a child between 25 lb to 75 lb.
The inequality for a child up to and including 26 lb will come under a car seat is designed for a child up to and including 26 lb. The inequality can be written as Child ≤ 26.
Therefore, the car seat appropriate for a child 33-lb will be shown by the inequality 25 < Child seat < 75.

Solution:
The point C' of the image coincides with point E of the preimage and D' of the image coincide with the point F of the preimage.
Explanation:
The regular hexagon have 6 corner points ABCDEF.
The complete angle about the center because it is a close figure as shown in given figure. It means the line from two consecutive vertices to the center of hexagon make an angle of because 6 lines from the vertices to the center divides the center angle in 6 equal parts.

(02.01)Polygon LMNP slides 5 units right and 4 units down on the coordinate plane. If the original measure of angle M was 50 degrees, what is the measure of angle M'? 40 degrees 45 degrees 50 degrees 130 degrees
Answer:
50°
Step-by-step explanation:
Transformation is the movement of one point from its initial location to a final location. If an object is transformed, all its points are transformed. Types of transformation is reflection, dilation, rotation and translation.
If an object is translated, it maintains its shape and size as well as the length of its sides and angles, only the location changes.
If polygon LMNP with ∠M of 50° is translated 5 units right and 4 units down to a new point, M' has the same angle measure. Hence ∠M' = 50°

2) How much 64% acid solution should be mixed with 12 gallons of a 38% acid solution in order to make a 52% acid solution?
Answer: 14 gallons of the 64% acid solution is needed
============================================================
Work Shown:
x = amount, in gallons, of the 64% acid solution
0.64x = amount of pure acid from the stuff we're adding in
0.38*12 = 4.56 = amount of pure acid from 38% solution
In total, we have 0.64x+4.56 gallons of pure acid out of x+12 gallons total
Dividing the two amounts will give us the decimal form of the percentage. Set this equal to 0.52 and solve for x
-----------
(0.64x+4.56)/(x+12) = 0.52
0.64x+4.56 = 0.52(x+12)
0.64x+4.56 = 0.52x+6.24
0.64x-0.52x = 6.24-4.56
0.12x = 1.68
x = 1.68/0.12
x = 14 gallons is the amount of the 64% acid solution we need to add in

Why use f(x) instead of y?
Answer:
The notation "f(x)" is exactly the same thing as "y"
Step-by-step explanation:
The effect of using f(x) instead of y is that it allows us to talk about f.
If we have an equation relating X to Y then that's a relationship between rwo nimbers.
For example if you have that y=
[tex]y = {x}^{3} [/tex]
...then that means that X and Y are some numbers obeying that equation
Lucero dibujo las diagonales de un polígono regular y se dio cuenta que tiene que trazar 7 diagonales más que el numero de lados. ¿cuanto es la suma de ángulos internos de ese polígono?
Answer:
The sum of all internal angles of this polygon is: [tex]900^o[/tex]
Step-by-step explanation:
Recall that the formula for the number of diagonals of a polygon with n-sides is given by the formula:
[tex]diagonals=\frac{n\,(n-3)}{2}[/tex]
and since Lucero noticed that the number of digonals was 7 more that the number of sides, then, these two quantities (n + 7) and the number of diagonals must be equal. we can set an equation stating such, and solve for "n" (number of sides of the polygon):
[tex]n+7=\frac{n\,(n-3)}{2} \\2(n+7)=n(n-3)\\2\,n+14=n^2-3\,n\\n^2-3\,n-2\,n-14=0\\n^2-5\,n-14=0\\(n-7)\,(n+2)=0\\[/tex]
therefore n = 7 or n = -2
The only answer with meaning is the first one (7 sides), since a polygon must have a positive number of sides.
Now that we know the number of sides of the polygon, we can find what the sum of its internal angles should give, based on the equation;
Addition of internal angles of a polygon is = [tex](n-2)\,180^o[/tex]
Which in our case renders:
[tex](n-2)\,180^o=(7-2)\,180^o= 5\,(180^o) = 900^o[/tex]

The average low temperature by month in Nashville is represented by the function
f(x)=-1.4x2 + 19x +1.7, where x is the month. Find the average rate of change from March to
August.
Answer:
33Step-by-step explanation:
Given the average low temperature by month in Nashville is represented by the function f(x)=-1.4x² + 19x +1.7, where x is the month, the average rate of change is expressed as d[f(x)]/dx = 2(1.4x) + 19
d[f(x)]/dx = 2.8x + 19
Since the number of months between March and August is 5 months and x is in months, hence we will substitute x = 5 into the resulting function to get the average rate of change from March to August as shown;
d[f(x)]/dx at x = 5
= 2.8(5)+ 19
= 14 + 19
= 33
Hence the average rate of change from March to August is 33
James just won the lottery for $30 million! He has two choices: first, he may receive $15 million today, or he may receive equal payments of $1 million a year for the next 30 years. Currently, the discount rate that he could invest the $15 million is 7% compounded annually. What should James do?
Answer:
The best option is the first one. It provides a higher present value.
Step-by-step explanation:
Giving the following information:
Option 1:
Receive $15,000,000 today.
Option 2:
Receive $1,000,000 for 30 years.
Discount rate= 7% compounded annually
To compare both options, we need to calculate the present value of Option 2. The option with the higher present value is the most convenient.
Option 2:
First, we need to determine future value:
FV= {A*[(1+i)^n-1]}/i
A= annual cash flow
FV= {1,000,000*[(1.07^30) - 1]} / 0.07
FV= $94,460,786.32
Now, the present value:
PV= FV/(1+i)^n
PV= 94,460,786.32 / (1.07^30)
PV= $12,409,041.18
The best option is the first one. It provides a higher present value.

Answer:
Solution : Option A and Option C
Step-by-step explanation:
To find the values of x that are not present in the domain, we can start by making the denominator equal to 0. This would make the fraction undefined, and hence will solve for the value(s) of x that do not belong to the function -
x² - 3x - 10 = 0,
(x + 2)(x - 5) = 0,
x = - 2 and x = 5
Domain {x | x ≠ - 2 ≠ 5 }
Hence our solution(s) are option a and option c
Answer:
[tex]\huge \boxed{x=5 \ \mathrm{and} \ x=-2}[/tex]
Step-by-step explanation:
The domain of a function are all possible values for x.
To find the domain of a rational function, we set the denominator equal to 0, and solve for x. Those values of x are not included in the domain, since the denominator of 0 would make the rational function undefined.
[tex]x^2-3x-10 =0[/tex]
Factoring left side of the equation.
[tex](x+2)(x-5)=0[/tex]
Setting the factors equal to 0.
[tex]x+2=0 \\ \\ x=-2 \\ \\ \\ \\ x-5=0 \\ \\ x=5[/tex]
The values of x that are not in the domain of the rational function are x = -2 and x = 5.
