g(x): 16 10 6 -4
Answers:
(infinity,1]
[-1,1]
R
The range of the function (f+g)(x) = x² - 1 will be ( -1, ∞ ). The correct option is B.
What are a domain and range?The range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f make up this set (x). A function's range is the set of values it can take as input. After we enter an x value, the function outputs this set of values.
Given that the function is f(x) = x²+2x-5. The function g(x) will be calculated by the data given in the table.
x -6 -3 -1 4
g(x) 16 10 6 -4
The function g(x) will be:-
g(x) = mx + c
m = ( 10 - 16 ) / ( -3 + 6 )
m = -6 / 3
m = -2
c = y - mx
c = 10 - 6
c = 4
g(x) = -2x + 4
The function ( f + g)(x) will be:-
( f + g)(x) = f(x) + g(x)
( f + g)(x) = x²+ 2x - 5 - 2x + 4
( f + g)(x) = x² - 1
At x = 0, the value ( f + g)(x) is -1. The range of the function is ( -1, ∞).

regular milk has 4% butterfat. how many litres of regular milk must be mixed with 90 l of milk with 1% butterfat to have milk with 2% butterfat?
20 litres of regular milk must be mixed with 90 l of milk with 1% butterfat to have milk with 2% butterfat.
From the data given,
Let us assume that the x litres of regular milk which have 4% butterfat is mixed.
The amount of butterfat in 40 L of milk with 1% butterfat will be = (40*.01)=0.4 L
The amount of butterfat in x L of milk with 4% butterfat will be =x *0.04=0.04 x
The amount of butterfat in (40+x) L (when both are mixed) of milk with 2% butterfat will be =(40+x)*(0.02)=0.02(40+x)
Since we are aware that the total quantity of butterfat in each type's individual milk will match the total amount of butterfat in the final milk.
Therefore we can set up the equation which will be like this:
0.4+0.04 x=0.02(40+x)
Now solving the above equation for getting the value of "x"
0.4+0.04 x=0.02(40+x)
=>0.4+0.04x=0.8+0.02x
=>0.04x-0.02x=0.8-0.4

To make milk with 2% butterfat, 20 liters of ordinary milk must be combined with 90 liters of 1% butterfat milk.
Assume that 4% butterfat normal milk in an amount of X litres is combined. 40 L of milk with 1% butterfat will contain (40 x 0.01)=0.4 L of butterfat. In X L of milk containing 4% butterfat, the amount of butterfat is equal to =(X liter) x (0.04)=0.04 X.
When both are combined, (40+X) L of milk with 2% butterfat will contain =(40+X)*(0.02)
=0.02(40+X) grams of butterfat.
We know that the overall amount of butterfat in each type's individual milk will be the same as the total amount of butterfat in the finished milk.
As a result, we may construct the equation, which looks like this:
0.4+0.04X = 0.02(40+X)
To find the value of "X," solve the equation above.
0.4+0.04 X=0.02(40+X)
= 0.4+0.04X=0.8+0.02X
= 0.04X-0.02X=0.8-0.4

Here to solve the probability of this sum, it is difficult to say that the probability without no information.
(a)The probability that the team wins the debate with a junior giving the closing argument is 0.083.
(b) To design a simulation to estimate the probability that a sophomore is never selected to give the closing argument in the next 3 debates, one could randomly assign a closing argument speaker for each debate using a table of random digits. The table would have two columns: one for sophomores and one for juniors and seniors. The probability of a sophomore being selected would be 20%, and the probability of a junior or senior being selected would be 80%. The simulation would be run for 3 debates and the number of times a sophomore is never selected would be recorded. This process would be repeated a number of times to estimate the probability of a sophomore never being selected. (e) Based on the dot plot, it appears that there is some evidence that the sophomores were purposely ignored, as there are several simulated sets of 5 debates where a sophomore was not selected to give the closing argument. However, without more information, it is difficult to say for certain if this is enough evidence to support the claim that the sophomores were purposely ignored.

Country B is more efficient than Country A when it comes to producing cars and tanks.
Country A takes twice as long to produce a car (30 minutes) than Country B (12 minutes). However, Country A takes 20 minutes to produce a tank while Country B takes 10 minutes, cutting the amount of time in half.
We can measure the efficiency of each country by calculating the number of cars and tanks each country can produce in an hour. We can do this using the following formula:
Cars per hour = (60 minutes/minutes to produce car)
Tanks per hour = (60 minutes/minutes to produce tank)
For Country A, the number of cars produced in an hour is (60 minutes/30 minutes) = 2 cars per hour and the number of tanks produced in an hour is (60 minutes/20 minutes) = 3 tanks per hour.
For Country B, the number of cars produced in an hour is (60 minutes/12 minutes) = 5 cars per hour and the number of tanks produced in an hour is (60 minutes/10 minutes) = 6 tanks per hour.
Therefore, Country B is more efficient than Country A when it comes to producing cars and tanks.

T
6 ft
1
20 ft
Answer: The wall that Randy is painting is 20 feet long and 6 feet high. The two corners that he is not painting are triangular in shape and are each 6 feet high and 4 feet wide.
So the area of the wall that Randy is going to paint is:
20 ft * 6 ft = 120 sq ft
The area of the two corners that Randy is not painting is:
(1/2) * 4 ft * 6 ft = 12 sq ft
Therefore, the total area that Randy needs to paint is:
120 sq ft - 12 sq ft = 108 sq ft
One gallon of paint will cover 100 square feet.
So Randy will need to purchase 108 sq ft / 100 sq ft/gallon = 1.08 gallons of paint.
Randy will have to purchase 1.08 gallons of paint.

Before the baseball season begins, a field manager outlines the "on-deck" circle with chalk and covers the area with dirt.
If the "on-deck" circle has a diameter of 6 feet, about how long is the chalk outline?
The length of the chalk outline is 19 feet.
The field is circular and the line drawn by chalk is the length of the rim of the circular field and is called the circumference. It can be calculated from the radius(or diameter) of the circle.
The formula of the circumference of a circle:
Circumference of circle [tex]= 2 * \pi * r = \pi * d[/tex]
where r means the radius of the circle and d means the diameter of the circle.
The diameter d = 2 times of radius
Thus, we have:
Length of a chalk outline [tex]= \pi * d = \pi * 6 = 3.14 * 6 = 18.84 = 19 feet[/tex]
So, the length of the chalk outline is 19 feet.

The value of cosθ = 0.5
The correct option is (A).
Now, According to the question:
Basic Trigonometric Function Formulas:
By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.
Remember that in a right triangle, we have that:
cos(θ) = (adjacent cathetus)/(hypotenuse)
Here we have:
θ = 60°adjacent cathetus = 1hypotenuse = 2Replacing all that in the equation we get:
cos(60°) = 1/2 = 0.5
Hence, the value of cosθ = 0.5
