Answer:
EG = 6 in.
Step-by-step explanation:
EG is congruent to DF and DF is 6 in. so EG would be 6 in.
Answer:
6 in.
Step-by-step explanation:
DF's length is congruent ( same ) to EG's length which is shown by the one mark on each side
Since DF's length is 6 inches, EG's length is also 6 inches.
Therefore,the answer is 6 in( inches )

Use logarithmic differentiation to find dy/dx. y = (1 + x)^1/x, x > 0
Use exp/log functions to rewrite y as
[tex]y = (1+x)^{\frac1x} \implies y = \exp\left(\ln\left(1+x)^{\frac1x}\right)\right)[/tex]
One of the properties of logarithms lets us bring down the exponent, so
[tex]y = \exp\left(\dfrac{\ln(1+x)}x\right)[/tex]
Now take the derivative of both sides with respect to x. By the chain and quotient rules,
[tex]\dfrac{dy}{dx} = \exp\left(\dfrac{\ln(1+x)}x\right) \times \dfrac{\frac x{1+x} - \ln(1+x)}{x^2}[/tex]
Simplify:
[tex]\boxed{\dfrac{dy}{dx} = \frac{x - (1+x)\ln(1+x)}{x^2(1+x)} (1+x)^{\frac1x}}[/tex]

Step-by-step explanation:
B stands for the total amount of chocolate bars they started with.
Gabby ate 1/4 of those chocolate bars.
4 3/4 of the chocolate bars were left after that.
So, total amount of bars - what Gabby ate = chocolate bars that are left

Which product range generated the most profit over all???
Answer:
Blue label
Step-by-step explanation:
All that matters here is # of bottles sold * profit per bottle.
If you multiply these 2 values for each row you will see the blue label has the highest amount of profit.
Among all the product ranges blue label generated the most profit of $5625.
What is profit?Profit is basically the difference between the total revenue and the total cost of the product.
Profit=Total Revenue- Total cost.
How to calculate profit?We know that Average profit= total profit/ number of units.
So the profit will be as average profits* number of units.
So the profit of product ranges will be =average profit * number of bottles.
Profit of red label=1.12*3000
=$3360
Profit of black label=1.5*2000
=$3000.
Profit of gold label=2.75*1000
=$2750
Profit of white label=1.20*2750
=$3300
Profit of blue label=2.25*2500
=$5625.

3/4 of ... is 12 I neeed your help please help me
Answer:
The number is 16.
Step-by-step explanation:
So we need to find 3/4 of a number to get 12.
We don't know what the number is, so we assign it a variable. We will assign the variable x and try to solve it.
We translate our problem into an equation. Since x is the variable and we multiply by 3/4, we get the value of 12, which is exactly what we are trying to do.
(3/4)(x) = 12
To solve, we multiply both sides by 4/3, because in order to solve for x (the variable), it needs to be separated and isolated from everything else.
(4/3) * (3/4)(x) = (4/3) * 12
4/3 * 3/4 = 1 and (4*12)/3 = 48/3 = 16
x = 16
The number is 16.
A. 108
B. 792
C. 891
D. 126
Answer:
C. 891.
Step-by-step explanation:
This is a regular nonagram ( has 9 sides) so the area is the sum of 9 congruent triangles.
Area of a triangle = 1/2 * base * height
Area of 1 triangle in this polygon = 1/2 * 12 * 16.5
Area of the polygon = 9 * 1/2 * 12 * 16.5

Answer:
50
Step-by-step explanation:
We are finding the surface area of a circle here. which is pie r ^2 ( the formula) so the radius is 4. So we do pie 4^2 which equals 50.26548246 which is approximately 50.
Answer:
First, we must know the formula for the area of a circle.
The formula for the area of a circle is;
A = π[tex]r^{2}[/tex]Where 'π' is pi(22/7 or 3.14), and 'r' is the radius which is being squared.
Plug in what you know;R(radius) = 4 feet.
So,
A = π[tex]r^{2}[/tex]
Will be;
A = π(4^2) ← what I mean by " ^ ", I mean "to the power of".
Simplify:-
A = 3.14(16)
A = 50.24 feet is the area.

Answer:
[tex]1436.76... units^3[/tex]
Step-by-step explanation:
Recall the formula for the volume of a sphere.
[tex]V = \frac{4}{3} \pi r^3[/tex]
The question gives you diameter. As you know, diameter is twice the radius. Therefore, to convert diameter into radius, you divide the diameter by 2.
[tex]r = 14/2[/tex] [tex]= 7[/tex]
Now that you have the radius, all you need to do is plug it into the volume formula.
[tex]V = \frac{4}{3}\pi 7^3[/tex] = [tex]1436.76... units^3[/tex]

6. Kayla is planning to buy a new phone. Rongers charges $0 for down payment plus $127 monthly fee. Fidoll charges $363 for down payment plus $94 monthly fee.
a) When will the two plans charge the same amount (the same number of months for both plans)?
b) If both plans are contracted for 2 years (24 months), which plan would you recommend to Kayla? Explain.
Answer:
See below ↓↓
Step-by-step explanation:
Plan 1
0 + 127xPlan 2
363 + 94xPart A
Equating them
⇒ 127x = 363 + 94x
⇒ 33x = 363
⇒ x = 11 months [They will be same at this point]
Part B
⇒ Plan 1 : 127(24) = $3048
⇒ Plan 2 : 363 + 94(24) = 2256 + 363 = $2619
⇒ I would recommend Plan 2 as it costs less for the time period of 2 years

-13x+2y=29 solve for y
Answer:
x = 2.38; substitute x to get yStep-by-step explanation:
solve for variable x.
move the term containing x to the left and the rest to the right.
add -2y to each side of the equation.
-13 +2y + -2y = 29 + -2y
combine like terms; 2y + -2y = 0
-13x + 0 = 29 + -2y
-13x = 29 + -2y
divide each side by -13 and then simplify;
x = -2.23 + 0.15
x = 2.38
