Using the given ratio we will see that each kilogram costs 15 dollars.
What is the cost of one kg of the mixture?We know that coffee at $12 per kg is mixed with coffee at $16 per kg in the ratio of 1: 3.
Then we have 4 kilograms, and the total cost of these 4 kg is:
1*$12 + 3*$16 = $60
Dividing that between the 4 kilograms:

Area of composite shapes, There is a pair of parallel sides in the following shape.
What is the area of the shape?
The following form has two parallel sides, and, in accordance with the provided assertion, its area is 21 cm².
What does mathematicians mean by area?Area is the entire amount of space occupied by a flattened (2-D) surface or form of an item. The area of a planar figure is the space that its perimeter encloses. The quantity of unit rectangles that completely encircle a closed figure's surface is its area. Square units such as cm² and m² are used to measure area.
The ratio will also be 1/2 * (bases 1 + base 2) * length since it is a trapezium.
So, 1/2 * ( 9+5) * 3
= 1/2 * 14 * 3

A) Find an equation for the line perpendicular to the tangent line to the curve y=x^3-4x+6 at the point (2,6)
-The equation is y=
b) What is the smallest slope on the curve? At what point on the curve does the curve have this slope?
-The smallest slope on the curve is
-The curve has the smallest slope at the point
c) Find equations for the tangent lines to the curve at the points where the slope of the curve is 8.
Answer:
f(x) = x³ - 4x + 6
f'(x) = 3x² - 4
a) f'(2) = 3(2²) - 4 = 12 - 4 = 8
6 = 8(2) + b
6 = 16 + b
b = -10
y = 8x - 10
b) 3x² - 4 = 0
3x² = 4, so x = ±2/√3 = ±(2/3)√3
= ±1.1547
f(-(2/3)√3) = 9.0792
f((2/3)√3) = 2.9208
c) 3x² - 4 = 8
3x² = 12
x² = 4, so x = ±2
f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6
6 = -2(8) + b
6 = -16 + b
b = 22
y = 8x + 22
f(2) = 6
y = 8x - 10
The equation perpendicular to the tangent is y = -1/8x + 25/4
-The smallest slope on the curve is 2.92
The curve has the smallest slope at the point (1.15, 2.92)
The equations at tangent points are y = 8x + 16 and y = 8x - 16
Finding the equation perpendicular to the tangentFrom the question, we have the following parameters that can be used in our computation:
y = x³ - 4x + 6
Differentiate
So, we have
f'(x) = 3x² - 4
The point is (2, 6)
So, we have
f'(2) = 3(2)² - 4
f'(2) = 8
The slope of the perpendicular line is
Slope = -1/8
So, we have
y = -1/8(x - 2) + 6
y = -1/8x + 25/4
The smallest slope on the curveWe have
f'(x) = 3x² - 4
Set to 0
3x² - 4 = 0
Solve for x
x = √[4/3]
x = 1.15
So, we have
Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6
Smallest slope = 2.92
So, the smallest slope is 2.92 at (1.15, 2.92)
The equation of the tangent lineHere, we set f'(x) to 8
3x² - 4 = 8
Solve for x
x = ±2
Calculate y at x = ±2
y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)
y = (2)³ - 4(2) + 6 = 6: (2, 0)
The equations at these points are
y = 8x + 16
y = 8x - 16

Write 34% as a fraction in simplest form
Answer:
The answer is that the simplest fraction form of 34% is 17/50
Step-by-step explanation:
Both the numerator and denominator of the fraction 34/100 can only be divided by 2, to satisfy creating its simplest form.
34% = 17/50
Have an awesome day! :D
Answer:
\(\frac{17}{50}\)
Step-by-step explanation:
To write any fraction as a percent, remember perCENT means per 100. Think of 100 cents in a dollar. So 34 perCENT means 34 of 100, which you write as \(\frac{34}{100}\).
Simplest form means to reduce, so you see if there is any number you can divide out of the top and the bottom.
\(\frac{34}{100}\) = \(\frac{17*2}{50*2}\)= \(\frac{17}{50}\)

Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = \(\frac{1}{2}\) x + 3 ← is in slope- intercept form
with slope m = \(\frac{1}{2}\)
• Parallel lines have equal slopes , then
y = \(\frac{1}{2}\) x + c ← is the partial equation
to find c substitute (2, - 4 ) into the partial equation
- 4 = \(\frac{1}{2}\) (2) + c = 1 + c ( subtract 1 from both sides )
- 5 = c
y = \(\frac{1}{2}\) x - 5 ← equation of parallel line

Model with Mathematics The outline of a park is
shown in the diagram. Each square on the grid represents
a square yard. Use shapes to model the area of the park.
Explain your reasoning and justify your calculations.
Answer:
We are trying to calculate the area of the park by modeling it with shapes. To start, the larger rectangle (green) toward the top is the easiest to calculate. Its length is 8 yards and its width is 4 yards, so the area would be 8 x 4 = 32 yards^2.
Next, the 3 rectangles at the bottom (white). The one in the middle has a length of 4 yards and a width of 3 yards, so its area is 4 x 3 = 12 yards^2. The two rectangles to either side are the same size, so together their area will be 2 x 4 x 3 = 24 yards^2.
Now that we have modeled the park with 3 shapes, we need to add the areas together to get the total area. So, we have 32 + 12 + 24 = 68 yards^2. The total area of the park is 68 yards^2.
Step-by-step explanation:
The area of the park is about :
95 + 27 = 122 yards
We have the following information available from the question is:
The outline of a park is shown in the diagram. Each square on the grid represents a square yard. Use shapes to model the area of the park.
Now, According to the question:
Each square on the grid represents a square yard, and as we can see from the figure that the complete square is about 95, the incomplete grid is about 27,

also for pyr:
- surface area
- lateral area
- volume
Answer:
Lateral Area = 624 square units
Surface area = 1,200 square units
Volume = 960 cubic units
Step-by-step Explanation:
==>Given:
Dimensions of the square pyramid as shown in the figure are:
length of 1 side of the square base (s) = 24
Slant height (l) = 13
Perpendicular height (h) = ?
==>Required:
a. Lateral area (L.A) = 4 × ½sl
b. Surface Area (S.A) = Base area (s²) × Lateral area (4 × ½sl)
c.Volume of the pyramid = ⅓ × Base area (s²) × perpendicular height (h)
==>SOLUTION:
a. Lateral area (L.A) = the area of the 4 lateral faces of the pyramid, which are triangular faces.
L.A = 4 × ½sl
From the figure given, s = 24; l = 13,
Therefore, L.A = 4 × ½ × 24 × 13
= 4 × 1 × 12 × 13
Lateral Area = 624 square units
b. Surface Area (S.A) = Base area (s²) × Lateral area (4 × ½sl)
Base area (s²) = 24² = 576 square units
Lateral area (4 × ½sl) = 624 square units
Therefore, total surface area = 576 + 624
= 1,200 square units
c. c.Volume of the pyramid using the formula ⅓ × Base area (s²) × perpendicular height (h)
Base area (s²) = 576 square units
Perpendicular height (h) is not given in the figure = h
Since already know the slant height (s), let's use Pythagorean theorem to find the perpendicular height (h) bearing in mind that a right triangle is formed in the middle of the pyramid as illustrated in the figure attached below.
The base of the right triangle = ½ of side length of the base (s) = ½ × 24 = 12
The hypotenuse (l) = 13
Therefore using the Pythagorean Theorem formula a² + b² = c², let's find the perpendicular height (h).
Where,
a² = h²
b² = (½s)² = 12²
c² = l² = 13²
Thus, h² + 12² = 13²
h² = 13² - 12²
h² = 169 - 144
h² = 25
h = √25
h = 5
==>Volume of pyramid (V) = ⅓ × Base area (s²) × perpendicular height (h)
V = ⅓ × 576 × 5
V = ⅓ × 2,880
V = 960 cubic units

If an object with mass m is dropped from rest, one model for its speed v after t seconds, taking air resistance into account, is given by the following where g is the acceleration due to gravity and c is a positive constant describing air resistance.
v=((mg)/c) \(1-e^(-(ct)\/m)\)
(a) Calculate the following.
lim_(t->infinity) v= __________
What is the meaning of this limit?
1)It is the time it takes the object to reach its maximum speed.
2)It is the speed the object approaches as time goes on.
3)It is the time it takes for the object to stop.
4)It is the speed the object reaches before it starts to slow down.
(b) For fixed t, use l'Hospital's Rule to calculate the following.
lim_(c->0**+) v= ___________
What can you conclude about the velocity of a falling object in a vacuum?
1)The speed has nothing to do with the elapsed time. The heavier the object is the faster it will fall.
2)The speed is jointly proportional to the time and the mass. The longer the object falls and the heavier it is the faster it will fall.
3)The speed is proportional to the elapsed time. It doesn't depend on the mass. The longer the object falls the faster it will fall.
The speed is proportional to the elapsed time. It doesn't depend on the mass. a)Mg/c is the limit and b)gt is the limit
What is speed?
Speed is defined as the rate of change of distance with time. It has the dimension of distance by time. Thus, the SI unit of speed is given as the combination of the basic unit of distance and the basic unit of Timea) lim t-->∞ v = mg/c
mg/c is the limit
2)It is the speed the object approaches as time goes on.
