The graph of a translated exponential function is shown below. Its parent function is y = 4x.
If the graph is asymptotic to y = -3 and contains the points (2, -2) and (3, 1), what is the equation of the function?
PLEASE HURRY!
The graph of a translated exponential function is shown below. Its parent function is y = 4x.?
The function has been translated down 3 units and right 2 units. The equation of the graphed function is
.. y = -3 +4^(x -2)
If the graph is asymptotic to y = -3 and contains the points (2, -2) and (3, 1), what is the equation of the function?

theres another answer choice thats four but it got cut out please help pretty easy question
Answer:
We conclude that:
f(g(3)) = 2
Hence, option B is correct.
Step-by-step explanation:
Given the f(x) table
x 2 3 4 5
f(x) 0 1 2 3
Given the g(x) table
x 1 2 3 4
g(x) 1 2 4 8
We need to determine f(g(3)).
In order to determine f(g(3)), first, we need to determine g(3)
It is clear from the table of g(x),
at x = 3, g(3) = 4
so
f(g(3)) = f(4)
Now, we need to check the value of f(4) at x = 4 using the table f(x)
It is clear from the table of f(x),
at x = 4, f(4) = 2
Thus,
f(g(3)) = f(4) = 2
Therefore, we conclude that:
f(g(3)) = 2
Hence, option B is correct.
The angular speed for a Wind turbine with blades turning at a rate of 19 revolutions per minute is
Answer
The answer to the question is 3.157 revolutions per second.
Step-by-step explanation:
The reason is because speed is the distance the object travels in a second.
So, we know that the wind turbine is moving 19 revolutions per minute, so therefore to find the number of rotations the wind turbine is doing per second we have to do 60/19 because there is 60 seconds in a minute.
Therefore, if we do that equation we get the answer, as 3.157 revolutions per second!

find the slope of the line going through the point (0,3) and (0,4)
Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
[tex]\frac{(4)-(3)}{(0)-(0)} \\= \frac{4-3}{0-0}\\=\frac{1}{0}[/tex]
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
an Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?
Answer:
45
Step-by-step explanation:
This is a trick question. Since they only get three purchases in by 7 weeks, the answer will be 15 times 3 or 45.
(If I'm wrong and it's not a trick question, then it's 15 times 3.5 or 52.5)
Hope this helps!
Find the standard form of the equation for the conic section represented by x^2 + 10x + 6y = 47.
Answer:
The standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
Step-by-step explanation:
We know that:
[tex]4p\left(y-k\right)=\left(x-h\right)^2[/tex] is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.
Given the equation
[tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex]
Rewriting the equation in the standard form
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]
Thus,
The vertex (h, k) = (-5, 12)
Please also check the attached graph.
Therefore, the standard form of the equation for the conic section represented by [tex]x^2\:+\:10x\:+\:6y\:=\:47[/tex] is:
[tex]4\left(-\frac{3}{2}\right)\left(y-12\right)=\left(x-\left(-5\right)\right)^2[/tex]

whats the answer to
-7y=7x+21
Answer:
y = -x - 3
x = -y - 3
Step-by-step explanation:
If solving for y,
-7y = 7x + 21
-y = -x + 3 (dividing everything by 7)
y = -x - 3
If solving for x,
-7y = 7x + 21
-y = -x + 3
x = -y - 3
Find the volume of this cylinder.
Give your answer to 1 decimal place.
11 cm
14 cm
Answer:
1,330.5 cm³
Step-by-step explanation:
Volume of cylinder = πr²h
Where,
r = ½ of 11 = 5.5
h = 14 cm
Plug in the values
Volume = π × 5.5² × 14
Volume = π × 423.5
Volume = 1,330.5 cm³ (1 d.p)
Brock divided all of his games into 3 shelves, and there were at least 12 games on each shelf. What inequality matches this scenario
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Brock divided all of his games into 3 shelves, and there were at least 12 games on each shelf.
The inequality that matches this scenario will be:
x ≥ 12.
Since there were at least 12 games, we would use the greater than or equal to sign.

solve each linear system by GRAPHING. CHECK YOUR ANSWER
2.) x - y = 6
2x = 12 + 2y
3.)1/2 x - y = 4
2y = x + 6
Answer:
2.) Infinitely many solutions
3.) No solutions
Step-by-step explanation:
To solve systems of equations graphically, you need to find where they intersect
2.) First put each equation in the form y=mx+b
x-y=6 -> y= x-6
2x=12+2y -> y= x-6
Then, graph each line
Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.
To check, plug a point in from the graph into both equations and you should get 0=0
3.) First put each equation in the form y=mx+b
1/2x-y=4 -> y=1/2x-4
2y=x+6 -> y=1/2x+3
Then, graph each line
Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.
To check your answer, you would one equation as the y in the other equation.
2(1/2x-4)=x+6, then solve for x
Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!

One angle of a triangle measures 75. The other two angles are in a ratio of 5:16. What are the measures of those two angles?
Answer:
25 and 80
Step-by-step explanation:
180 - 75 = 105
105 / (5+16) = 5
multiply each side of the ratio 5:16 by 5
5x5 : 16x5 = 25:80

the answer choices are
a. 32m
b. 225 m
c. 5 m
d. 15 m
Answer:
d. 15 m
Step-by-step explanation:
hypotenuse (h) = 25 m
base (b) = 20 m
perpendicular (p) = ?
By using Pythagoras theorem we get
p = √h² - b²
= √ 25² - 20²
= √ 225
= √ 15²
= 15 m

Answer: 180
Step-by-step explanation:
When added together, Interior angles of a triangle are always equal to 180 degrees.
Answer:
∠FHG=120°
Step-by-step explanation:
first you calculate the angles of the triangle NGH
this is isoceles triangle, so there's 2 equal angles
and as shown, the 2 same angles are having 2 lines in each one, this 2 lines represents that the 2 angles are same
so both are 20°
any triangle has a sum of 180° of interior angles
so 180-(H+G)=the angle below N
180-(20+20)=140°
the angle below N is same as N because they're vertically opposite
140 is an exterior angle
and the exterior angle is equal to the 2 far angles
140=40+∠FHN
140-40=100°
so ∠FHN=100°
∠FHN+∠NHG=∠FHG
100+20=120°
so ∠FHG=120°

Step-by-step explanation:
10 quarters= $2.5 which is 25 dimes
10 nickels= $0.5 which is 5 dimes
10 dimes= $100
100+25+5= 130 dimes = $13
13/100 = %0.13
