The graph of f is translated a whole number of units horizontally and vertically to obtain the graph of h
The function f is defined by f(x) = square root of x
Write down the expression for h(x).
The expression for h(x) is,
⇒ h (x) = √(x - 2) + 4
Now, Given that;
Initially the graph f (x) is shifted horizontally to the right.
When the graph shifts to right the function then becomes
f (x) → f (x-b)
Where b is the units by which it is shifted towards right .
So, in the figure we can see that it is shifted 2 units to the right .
So, f(x) → f(x-2)
Since f(x) is,
⇒ f (x) = √x
So, f (x-2) = √x - 2
Now, the new obtained graph is again shifted vertically upward
When the graphs shifts upward;
⇒ f(x) → f(x) + b
where b is the units by which it is shifted upward
So, our obtained f(x-2) when shifted upward by 4 units so using the above given transformation of upward shift
i.e. f(x) → f(x) + b
So, Our new graph h(x) = f(x-2) + 4
⇒ h (x) = √(x - 2) + 4

0.3. e^3x = 27
Taking logs of both sides:
ln (0.3. e^3x) = ln 27
ln (0.3) + ln e^3x = ln 27
ln e^3x = ln 27 - ln(0.3)
3x = ln 27 - ln 0.3
3x = ln(27/0.3) = ln 90
x = 1/3 ln 90

Answer:
notebook: $4thumb drive: $25Step-by-step explanation:
You want the cost of a notebook and a thumb drive when 5 notebooks and 15 thumb drives costs $395, while 12 notebooks and 8 thumb drives cost $248.
EquationsThe two purchases can be described by the equations ...
5n +15d = 395 ⇒ n +3d = 7912n +8d = 248 ⇒ 3n +2d = 62SolutionSubtracting the second equation from 3 times the first, we have ...
3(n +3d) -(3n +2d) = 3(79) -(62)
7d = 175
d = 25 . . . . . . . divide by 7
Substituting into the first equation gives ...

Additional comment
It is often easier to solve a system of equations when they are written in standard form. Here, we made the coefficients mutually prime by dividing each equation by the greatest common factor. For the first equation, we divided by 5; for the second equation, we divided by 4. This is especially useful if one of the coefficients ends up being 1.

In September 2016, the cost of gasoline in Berlin was around 1.21 euros per liter.
What would the equivalent cost be in U.S. dollars per gallon?
1 U.S. dollar ~ 0.896 euros
1 gallon 3.785 liters
Using proportions, it is found that the equivalent cost in U.S. dollars per gallon would be of 5.11.
What is a proportion?A proportion is a fraction of total amount, and the measures are related using a rule of three.In September 2016, the cost of gasoline in Berlin was around 1.21 euros per liter. Hence, per gallon, that is, per 3.785 liters, we use a rule of three to find the cost.
1.21 euros - 1 liter
x euros - 3.785 liters
Applying cross multiplication:
\(x = 1.21(3.785) = 4.57985\)
Cost of 4.57986 euros per gallon. Since 1 U.S dollar is equivalent to approximately 0.896 euros, we have that:
1 dollar - 0.896 euros
x dollars - 4.57986 euros
Applying cross multiplication again:
\(0.896x = 4.57986\)
\(x = \frac{4.57986}{0.896}\)
\(x = 5.11\)
The equivalent cost in U.S. dollars per gallon would be of 5.11.

A line has a slope of -2 and passes through the point (-2, -3). Write its equation in slope-
intercept form.
The slope-intercept form of a line's equation is y = mx + b, where m is the slope of the line and b is the y-intercept. We can use the given slope and point to solve for the y-intercept and write the equation in slope-intercept form.
Given: Slope (m) = -2 and point (-2, -3)
Step 1: Use the point-slope form of a line's equation to find the equation of the line in point-slope form:y - y1 = m(x - x1) (where x1,y1 are the coordinates of the given point)y - (-3) = -2(x - (-2))y + 3 = -2(x + 2)Step 2: Simplify the equation by distributing the -2:y + 3 = -2x - 4Step 3: Solve for y by subtracting 3 from both sides of the equation:y = -2x - 7Therefore, the equation of the line in slope-intercept form is y = -2x - 7.x/5 + 7 = 16 X= answer

Figure T

followed by a
Figure U
5 6 7 8 9 10 11 12
To map Figure T to Figure U, we can use the following sequence of transformations:
Translation: Move the figure 10 units to the right and 12 units down.
This will shift all the points in Figure T by the specified distances.
Reflection: Reflect the figure across the vertical axis.
This will reverse the order of the points horizontally.
Translation: Move the figure 5 units to the right and 10 units up.
This will shift all the points in Figure T (which is now reflected) by the specified distances.
The resulting sequence of transformations would be:
Translation (10 units right, 12 units down) -> Reflection (across the vertical axis) -> Translation (5 units right, 10 units up)
Applying these transformations to Figure T should result in Figure U.
The current in an electrical conductor varies inversely as the resistance of the conductor. If the resistance is 240 ohms when the current is 12 ampere, what is the current when the resistance is 540 ohms?
The resistance is 540 ohms, the current in the conductor is approximately 5.33 amperes.
According to the given information, the current in an electrical conductor varies inversely to the resistance of the conductor. Inverse variation can be represented mathematically as follows:
Current * Resistance = Constant
Let's denote the constant as 'k'. We can use the initial values to find the value of 'k'.
When the resistance is 240 ohms and the current is 12 amperes:
12 * 240 = k
k = 2880
Now that we have the value of 'k', we can use it to find the current when the resistance is 540 ohms:
Current * 540 = 2880
Current = 2880 / 540
Current ≈ 5.33 amperes
Therefore, when the resistance is 540 ohms, the current in the conductor is approximately 5.33 amperes.

A tank is full of water. Find the work required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3 as the density of water. Assume r = 6 m and h = 2 m.)
The work required to pump the water out of the spout is 70.9 * 10⁶ joules which is 71 M Joules approx.
Let the spherical tank be divided into a series of horizontal disks.
Let x be the height of each disk, g = gravity and p = density
Volume of each disk = πr2dx
Where r is the radius of each disk and dx is the thickness
By Pythagoras r² = 6² - x²= 36 -x²
Therefore Volume = π*(36-x²)*dx cubic metres
The distance each disk has to be lifted to escape the top of the spout = 2 + 6-x meters = (8-x)
Work needed to lift each disk to outlet = distance * mass where
mass = volume * density * gravity
= pi(36-x²)*p*g = 9800pi(36-x²)dx
dW = (8-x)* 9800pi(36-x²)dx
Since we have already accounted for the height of the spout, the work required is obtained by integrating the above expression from the bottom of the tank to the top. In other words, - 6 to + 6.
W = ⌠(8-x)*9800pi(36-x2)dx = 9800pi⌠[288 - 36x - 8x² +x³]dx
The odd terms evaluate to zero and we can rewrite the above as 2* I from 0 to 6.
W = 9800pi*2 [288x - 8x³/3] at x = 6 = 1152*19600π Joules = 22579200π joules = 70963200j
Total work required = 70.9 * 10⁶ joules

Brianna made 9 1/4 bags of popcorn for a movie night with some friends. Together they ate 4 bags of it. How much popcorn was left?
There were 5 1/4 bags of popcorn left after eating 4 bags.
To find out how much popcorn was left after eating 4 bags, we need to subtract the amount eaten from the total amount Brianna made.
Brianna made 9 1/4 bags of popcorn, which can be represented as a mixed number. To perform calculations, let's convert it to an improper fraction:
9 1/4 = (4 * 9 + 1) / 4 = 37/4
Now, let's subtract the 4 bags eaten from the total:
37/4 - 4
To subtract fractions, we need a common denominator. The common denominator of 4 and 1 is 4. Therefore, we can rewrite the expression as:
37/4 - 4/1
Now, let's find a common denominator and subtract the fractions:
37/4 - 16/4 = (37 - 16) / 4 = 21/4
The result is 21/4, which is an improper fraction. Let's convert it back to a mixed number:
21/4 = 5 1/4
Therefore, there were 5 1/4 bags of popcorn left after eating 4 bags.

The perimeter of a rectangle is 50cm. The length is 2 more than three times the width. What is the length of the rectangle?
The length of the rectangle is 19.25 cm when it is 2 more than three times the width of 5.75 cm.
What is Perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines a two-dimensional shape or length in one dimension. A circle's or an ellipse's circumference is its perimeter. There are several applications for calculating the perimeter. The length of fence required to encircle a yard or garden is known as the calculated perimeter.
The perimeter (circumference) of a wheel/circle describes how far it can roll in one revolution. Similarly, the amount of string wound around a spool is proportional to the perimeter of the spool; if the length of the string were exact, it would equal the perimeter.
Given that,
Perimeter = 2(l + b) = 50cm
And also given that,
l = 2 + 3b
Substituting the value of l in perimeter we get
2((2 + 3b) + b) = 50cm
2(2 + 4b) = 50cm
4 + 8b) = 50cm
8b = 50 - 4
b = 46/8
b = 5.75
Substituting the value of b in l, we get
l = 2 + 3(5.75)
l = 19.25
Therefore, the length of the rectangle is 19.25 cm when it is 2 more than three times the width of 5.75 cm.

Answer:
Tanisha = 14 years
Ana = 7 years
Elicia = 16 years
Step-by-step explanation:
Let T = age of Tanisha
Let A = age of Ana
Let E = age of Elicia
Tanisha is twice as old as Ana:
T = 2A
⇒ A = (1/2)T
Elicia is 2 years older than Tanisha:
E = 2 + T
Sum of all their ages is 37:
A + E + T = 37
Substitute A = (1/2)T and E = 2 + T into A + E + T = 37 and solve for T:
⇒ (1/2)T + 2 + T + T = 37
⇒ (5/2)T = 35
⇒ T = 14
If T = 14, then
A = (1/2)T = (1/2) 14 = 7
If T = 14, then
E = 2 + T = 2 + 14 = 16
