Step-by-step explanation:
Given the three functions: f(x)=4(2) g(x)=8x² + 24x , and h(x)= 4x + 8
Label each function as quadratic, linear, or exponential.
f(x)=
g(x)=
h(x)=
Answer:
f(x)=exponential
g(x)= quadratic
h(x)= linear
Step-by-step explanation:
exponential function
[tex] {ab}^{x} [/tex]
Quadratic function
[tex]a {x}^{2} + bx + c[/tex]
Linear function
[tex]y = mx + c[/tex]
Hi there!
[tex] \large \boxed{ y = {a}^{x} \: \: (a \neq 0, \: a > 1)}[/tex]
The equation above is an exponential family type.
[tex] \large \boxed{y = a {x}^{2} + bx + c \: \: (a \neq 0)}[/tex]
The equation above is quadratic type.
[tex] \large \boxed{ y = mx + b}[/tex]
The last type above is a linear type.
Hence, the answers are:

Answer:
y = -2x + 5 [ 1st option ]
Step-by-step explanation:
Consider any two points , say
(1,3) (2,1)Firstly let's find the slope of the line as ,
=> m = y₁ - y₂ / x₁ - x₂
=> m = 3-1 / 1-2
=> m = 2/-1
=> m = -2
Third point is, (3 , -1) . Using slope point form .
=> y - y₁ = m ( x - x₁ )
=> y - (-1) = -2( x - 3)
=> y + 1 = -2x +6
=> y +2x +1-6=0
=> y +2x -5 = 0
=> y = -2x + 5
On looking at options first one is correct
Hence the equation of line is y = -2x + 5.The probability of an event ________ occurring is the complement. The probability of the event and its complement have a sum of___.
Answer:
Not, 1
Step-by-step explanation:
The complement of an event denoted as A', can be interpreted as not A. This means that elements not belonging to a A. In probabilistic term, if we have an event A, the complement is f A is the probability that event A does not occur.
The sum of an event A and its corresponding complement must equal to 1.
This is given by the complement rule ;
P(A) + P(A') = 1
Hence, P(A') = 1 - P(A)

which of the following points would be a solution to this system of liner inequalities?
Answer:
The solution to the system is all the points that satisfy both inequalities or the region in which the shading overlaps. Given the system of linear inequalities shown in the graph, let's determine which points are solutions to the system. The point (0, -1) is not a solution to the system of linear inequalities.

Answer:
uhhh is this a trick question lol
have a good day :D
Step-by-step explanation:
A faucet delivers water at a rate of 2.7 gallons per minute. Kenny needs to fill a 30-gallon tank. The tank already has 3 gallons of water in it. Let g represent the number of gallons of water in the tank after t minutes. Write an equation that can be used to find the number of minutes, t, which it will take to fill the tank with g gallons of water. Then find the number of minutes it will take until the tank is completely full.
Answer:
It will take 10 minutes to fill the tank completely.
Step-by-step explanation:
If the 30-gallon tank already has 3 gallons of water in it, then 27 more are needed to fill the tank. Thus, at time t = 0, g(0) = 3 gallons, and
g(t) = (3 gallons) + (2.7 gal/min)t, where t is the time in minutes.
At the time the tank is completely full, it holds 30 gallons. How long does this take to achieve: Set (3 gallons) + (2.7 gal/min)t equal to 30 gallons:
30 = 3 + 2.7t, or 27 = 2.7t, or t = 10 minutes
It will take 10 minutes to fill the tank completely.
Since there are no restrictions on the strings, we can think of this problem as drawing 5 random digits in sequence. There is a 9/10 chance each time we draw to NOT get a 4. Every time we draw, we multiply by 9/10 again until we've draw 5 digits. Thus, the answer is (9/10)^5 :)
Answer:
[tex]Pr = 0.59049[/tex]
Step-by-step explanation:
See Comment for Complete Question
Given that A has 5 digits. A digit in A can be chosen from 0 to 9 (10 digits).
However, selection without 4 means that we can only select from 0 to 3 and 5 to 9 (altogether, that is 9 digits)
The probability of selecting a number other than 4 in each of the digit is:
[tex]1st \to \frac{9}{10}[/tex]
[tex]2nd \to \frac{9}{10}[/tex]
[tex]3rd \to \frac{9}{10}[/tex]
[tex]4th \to \frac{9}{10}[/tex]
[tex]5th \to \frac{9}{10}[/tex]
So, the required probability is:
[tex]Pr = 1st * 2nd * 3rd * 4th * 5th[/tex]
[tex]Pr = \frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10}[/tex]
[tex]Pr = \frac{9^5}{10^5}[/tex]
[tex]Pr = \frac{59049}{100000}[/tex]
[tex]Pr = 0.59049[/tex]

.Find the point of intersection of the pair of lines. x + 5y = 8, -x + 2y = -1
Answer:
the point of interception is where the graphs meets
in this case we will solve using substition method
x + 5y = 8 .... 1
-x + 2y = -1 .....2
solve for the equation
x = 8 - 5y ...... 3
solve the equation in equation 2
-x + 2y = -1
-(8-5y ) + 2y = -1
-8 +5y + 2y = -1
7y = -1 + 8
7y = 7
divided by 7 on both sides
y = 1
solve the value of y in equation 3
x = 8 - 5y
x = 8 - 5(1)
x = 8 -5
x = 3
the point of interception (3 ; 1)
Wel and George each have a packet of 20 seeds. They are planting seeds in different rows of a garden. Each row is 10 yards long. Wel plants a seed every 4 feet, starting 4 feet from the end of her row. George plants a seed every 2 yards, starting 2 yards from the end of his row. What is the greatest number of full rows that each person can plant using just their packet of seeds? Enter the answers in the boxes. Wei can plant full rows. George can plant full rows.
Answer:
a) Wel can plant four full roes
b) George can plant five full rows
Step-by-step explanation:
The number of seeds in the packet of seeds Wel and George have, n = 20 seeds each
The length of each row of the garden = 10 yards = 30 feet
The distance between the seeds Wel plants, d = 4 feet
The point at which Wel starts to plant the seeds = 4 feet from the end of the row
The distance between the seeds George plants = 2 yards
The point George starts to plant the seeds = 2 yards from the ends his row
Therefore, we have;
a) The length of each row Wel plants her seeds, l = 10 yd. - 4 ft. = 26 ft.
The number of seeds she plants per row = The whole number part of l/d
l/d = 26 ft./(4 ft./seed) = 6.5 seeds
∴ The number of seeds she plants per row, s = 6 seeds
The number of rows Wels plants her seeds, r = The next whole number of the ratio, n/s =
n/s = 20/6 = 3.[tex]\overline 3[/tex]
∴ The number of rows Wels plants 4 full rows
Therefore;
Using just her packet of seeds, Wels can plant four rows in the garden
b) The length of each row George plants his seed = 10 yd. - 2 yd. = 8 yd.
The number of seeds he plants per row = 8 yd./row/(2 yd./seed) = 4 seeds/row
The number of rows he plants his seeds = 20 seeds/(4 seeds/row) = 5 rows
The number pf rows George plants his seeds = 5 rows
Using just his packet of seeds, George can plant 5 full rows
In circle H with m ∠ G H J = 90 m∠GHJ=90 and G H = 20 GH=20 units, find the length of arc GJ. Round to the nearest hundredth.
Answer:
180
Step-by-step explanation:
length of arc GJ ≈ 31.42 units.
What is the arc of a circle?A circle's arc is a bent portion of the circle's circumference. Its perimeter is determined by its two ends and the area of the circle that lies in between them. An arc's length or the angle it makes with the circle's center can be used to measure it.
The formula L = θr states that the length of an arc is inversely proportional to the radius of the circle and the angle it subtends. L is the length of the arc, r is the radius of the circle and θ is the angle the arc subtends in radians.
To find the length of arc GJ, we first need to find the circumference of the circle.
The circumference of a circle is given by the formula:
C = 2πr
where C is the circumference, π is a constant approximately equal to 3.14, and r is the radius of the circle.
Since GH = 20 units and HJ is the radius of the circle, we have:
HJ = GH = 20 units
So the radius of the circle is 20 units.
The formula for the length of the arc is 2πr(θ/360)
Since the angle is given 90, the length of the arc:
2*π*20(90/360)
=10 π
Therefore, the length of arc GJ is 10π or 31.42 units.

Priya makes bracelets for her online store. Her monthly business expenses are $520. She sells an average of 80 bracelets per
month. Based on the inequality below, if she wants to profit at least $1,240, how much should she charge, b, per bracelet?
80b - $520 > $1,240
A. Priya needs to charge at most $19 per bracelet.
B. Priya needs to charge at least $22 per bracelet.
C. Priya needs to charge at most $22 per bracelet
D. Priya needs to charge at most $29 per bracelet.
Answer:
B
Step-by-step explanation:
Profit = total revenue - total cost
total revenue = 80 x b
total cost = 520
the profit has to be at least $1240
80 x 22 = 1760
1760 - 520 = 1240
