Answer:
B, E and F
Step-by-step explanation:
This graph is a log which has an asymptote. This means the function does not cross it and does not have in its domain certain numbers. The asymptote is at -2. This means the domain is greater than -2.
The range is the y-values. With no restrictions here, the function includes all numbers.
This means B, E, and F are true.

The parent function f(x) = x3 is translated to form g(x), as shown on the graph. The translated function can be written in the form
g(x) = (x – h)3 + k.
Answer: First option
Step-by-step explanation:
By definition, the horizontal shift depends on the value of h and the vertical shift depends on the value of k.
[tex]f(x)=(x-h)^3[/tex] indicates that the function if shifted to the right h units.
[tex]f(x)=(x+h)^3[/tex] indicates that the function if shifted to the left h units.
[tex]f(x)=f(x)-k[/tex] indicates that the function if shifted down k units.
[tex]f(x)=f(x)+k[/tex] indicates that the function if shifted up k units.
Then:
If h is positive, the graph will shift to the right.
If k is negative, the graph will shift down.
As you can see in the graph, the function is shifted 4 units to the right and 2 units down. Therefore g(x) has the form:
[tex]g(x)=(x-4)^3-2[/tex]
Where:
[tex]h=4\\k=-2[/tex]

The sum of 3 times the value of x and 2 is equal to 4 less than 5 times the value of x. Witch equation can be used to find the value of x?
Write the written problem into an equation to get:
3x +2 = 5x -4
To solve:
Add 4 to each side:
3x+6 = 5x
Subtract 3x from each side:
2x = 6
Divide both sides by 2:
x = 6/2
x = 3
You didn't list the options so it could like like any of the equations I show above.
To solve such problems we need to know about expressions.
Part 1ExpressionIn mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
The complete equation is 3x+2 = 5x-4 and the value of x is 2.
Part 2Given information,
The sum of 3 times the value of x and 2 is equal to 4 less than 5 times the value of x.Solution
We can solve the information by dividing the statements into parts,
part A: "The sum of",
Meaning we need to add the two numbers.
part B: "3 times the value of x",
the first number is 3 times the value of x, therefore, 3x.
part C: "and 2 is equal to",
the second number is 2. also, "equal" shows that one side of the equation is over and explained.
So, till now we have got
3x + 2
part D: "4 less than"
meaning 4 is been deducted from a number.
part E: "5 times the value of x",
Now, it is showing us the number from which 4 is been deducted. therefore, the number is 5x.
Thus, the complete equation is 3x+2 = 5x-4.
Further, solving the equation,
[tex]3x+2=5x-2\\+2+2 = 5x-3x\\4 = 2x\\2x =4\\x =2[/tex]
Hence, the value of x is 2.

Suppose a wild fire is doubling in size every 6 hours. If the initial size of the fire was 1 acre, how many acres will the fire cover in 2 days?
Step-by-step explanation:
2 days= 24 hours in 1 day, so multiply that by 2 to get 48 hours total.
Now find the amount of time the wild fire doubles by dividing 48 total hours by 6. So it will double 8 times
The size was 1 acre. Let's multiply by 2, 8 times

The fire will cover 128 acres in two days.
The wildfire, which is doubling every 6 hours, would cover 256 acres of land over a two day period.
Explanation:The problem involves exponential growth, which is a concept in mathematics where a quantity increases exponentially over time. According to the problem, the size of the fire is doubling every 6 hours. So, we have 24 hours in a day, and two days would give us 48 hours.
Now, divide the total hours (48) by the hours it takes for the fire to double in size (6), we get 8. This is the number of times the fire doubles in size over a 2 day period.
Since the fire was initially 1 acre, after 8 doubles or in 2 days, it would cover 28 or 256 acres of land.

Answer:
y = x - 3Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept → (0, b)
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (7, 4) and (0, -3) → b = -3.
Substitute to the formula of a slope:

f. 6x - 2y = 0
g. 3y = x + 4
h. 2y = 5 - x
Answer:
f and b
Step-by-step explanation:
if you put them in y-intercept form, both slopes are 3
In b. it's easy to see that 3x has a slope of 3.
In f. it's not so obvious. Just solve for y or use the shortcut m = -a/b where a is the coefficient of x and b is the coeff of y.
hence -(6/-2)=3
Answer:
Step-by-step explanation:
assuming you know how to put the equations into y = m x + b already. All equations have to be put in that format to identify the slope. Parallel lines have the same slope.
a. y = -2x - 1; slope -2
b. y = 3x - 1; slope 3
c. y = 2x - 3; slope 2
d. y = 4x + 3; slope 4
e. y = x/2 - 1; slope 1/2
f. y = 3x; slope 3
g. y = x/3 + 4/3; slope 1/3
h. y = -x/2 + 5; slope -1/2
There are only 2 that are alike. b and f both have a slope of 3. all the other slopes are different.

15 feet to 33 ft percent of change
Answer:
120%
Step-by-step explanation:
See how much % of 15 and increase to 33 is.
33 - 15 = 18, so there is a change of 18 feet.
18/15 = 1.2
1.2 is 120% as a percent. So there is a 120% change from 15 to 33
Final answer:
The percent of change from 15 feet to 33 feet is found by dividing the difference between the values by the original value and then multiplying by 100, which results in a 120% change.
Explanation:
To calculate the percent of change from 15 feet to 33 feet, first, find the difference between the two values. The difference is 33 feet - 15 feet = 18 feet. Then, divide this difference by the original value (15 feet) and multiply the result by 100 to get the percentage. Thus, the percent of change is (18 feet / 15 feet) × 100 = 120%.
A kite has a string tired to its center. The kite is let out on 90ft of the string and the other end of the string is held at 4ft above the ground. From where the string is held, the angle of elevation to the center of the kite is 40°. If you maintain the same angle of elevation from where the string is held, how much more string would you need to let out for the kite to fly 10ft higher? Round to the nearest tenth of a foot.
Length of more string needed to fly the kite 10 feet higher is 15.55 ft.
What is angle of elevation?The angle of elevation is the angle between the horizon and the line of sight. If the line of sight is above the horizon, the angle formed is the elevation angle.
Given,
Height of the string above the ground = 4 feet
Angle of elevation = 40°
length of the string = 90 ft
sin 40° = x/90
0.643 = (x)/90
x = 57.87 ft
For 10 ft higher, let the length be 90 + y
sin 40° = (57.87 + 10)/(90 + y)
0.643 = (57.87 + 10)/(90 + y)
57.87 + 0.643y = 57.87 + 10
0.643y = 10
y = 10/0.643
y = 15.55 ft
Hence, 15.55ft more string is needed to let out kite to fly 10 ft higher.

Final answer:
To find the extra string needed to raise the kite by 10ft, we can use trigonometry and set up an equation based on the sine function. By plugging in the values and solving the equation, we find that you would need 37.7ft of extra string.
Explanation:
To find how much more string you would need to let out for the kite to fly 10ft higher, we can use trigonometry. First, let's find the height of the kite above the ground when 90ft of string is let out. We can use the sine function: sin(40°) = height / 90ft. Rearranging the equation, we find height = sin(40°) * 90ft = 57.7ft. Now, to find the extra string needed to raise the kite by 10ft, we can set up a similar equation: sin(40°) = (height + 10ft) / (90ft + x), where x is the extra string. Rearranging the equation, we get x = ((height + 10ft) / sin(40°)) - 90ft. Plugging in the values, we have x = ((57.7ft + 10ft) / sin(40°)) - 90ft = 37.7ft.

Find k so that the equation 9x^2 +12x+k =0 has one real number (double) root.
For one real (double) root, set discriminant [tex]\( \Delta \)[/tex] to zero: [tex]\( 144 - 36k = 0 \)[/tex]. Solve to get [tex]\( k = 4 \)[/tex].
To find the value of [tex]\( k \)[/tex] so that the equation [tex]\( 9x^2 + 12x + k = 0 \)[/tex] has one real number (double) root, we use the discriminant [tex](\( \Delta \))[/tex] of the quadratic equation. For a double root, [tex]\( \Delta = 0 \)[/tex].
The discriminant is given by [tex]\( \Delta = b^2 - 4ac \)[/tex], where [tex]\( a = 9 \)[/tex], [tex]\( b = 12 \)[/tex], and [tex]\( c = k \)[/tex].
Substitute these values into the discriminant formula:
[tex]\[ \Delta = (12)^2 - 4(9)(k) \][/tex]
[tex]\[ = 144 - 36k \][/tex]
For a double root, [tex]\( \Delta = 0 \)[/tex], so:
[tex]\[ 144 - 36k = 0 \][/tex]
[tex]\[ 36k = 144 \][/tex]
[tex]\[ k = \frac{144}{36} \][/tex]
[tex]\[ k = 4 \][/tex]
Therefore, [tex]\( k = 4 \)[/tex] to have one real number (double) root.
Based on the trend in the approximately how many free throws would a player be expected to make if he attempted 60 free throws
To gauge how many free throws a player would make out of 60 attempts, we need to know the player's free throw success rate. Assuming similar conditions to the example given where Carlos, the soccer player has a success rate of 65%, the basketball player would make approximately 39 successful free throws from 60 attempts.
Explanation:
The question seems to be asking how many free throws a player would be expected to make if he attempted 60 free throws. The missing information here would be the player's free throw success rate which isn't provided. However, let's use the example of Carlos from college soccer as an analogy; if Carlos has a success rate of 65%, then for every 100 attempts, he would make 65 goals. Now if the basketball player followed the same trend and had a success rate of 65%, and he attempted 60 free throws, we would calculate 65% of 60. This equals 39, therefore we would be expecting the player to make approximately 39 free throws.
