Answer:
4 for c < 02 for c > 0Step-by-step explanation:
You want the maximum possible number of solutions to the equation
||ax -b| +c| = d
AnalysisThe values of 'a' and 'b' represent a vertical scale factor and a horizontal shift, so don't really contribute to the number of possible solutions. That means we can consider only the equation ...
||x| +c| = d
Positive c
We know |x| is always positive, and may have the same value for two different values of x. For positive 'c', the outside absolute value function does nothing, so the equation is effectively ...
|x| = d-c
For d < c, there can be no solutions. For d = c, there will be one solution, and for d > c, there will be two solutions.
Negative c
When 'c' is negative, then sum |x| +c may have either sign. This gives rise to another pair of possible solutions, for a total of four solutions.
GraphThe attached graph shows the two cases. The red graph shows the left side expression with c > 0; the purple graph shows the left side expression with c < 0. The orange horizontal line represents a value of 'd'. The number of intersection points with that horizontal line is the number of possible solutions to the given equation.
For c > 0, there are two possible solutions.
For c < 0, there are four possible solutions.

“According to Masterfoods, the company that manufactures M&M’s, 12% of peanut M&M’s are brown, 15% are yellow, 12% are red, 23% are blue, 23% are orange and 15% are green. [Round your answer to three decimal places, for example: 0.123]”
A probability is a numerical representation of the likelihood or chance that a specific event will take place.
How to find the probabilities?12% of peanut M&M’s = brown
15% = yellow
12% = red
23% = blue
23% = orange
15% = green
Here, Probability of an event is represented as P
a) P(not green) = 100% - 15%
= 85%
= 0.85
b) P(yellow or red) = 15% + 12%
= 27%
= 0.27
c) P(three blue) = 0.23*0.23 *0.23
= 0.012 (rounded to 3 decimal places)
d) P(not green if you choose 6 )= \((0.85)^{6}\)
= 0. 377
e) P(at least 1 green if you choose 6 ) = 1 - 0.377
= 0.623
What is probability?Probability is the ability to happen. The subject of this area of mathematics is the occurrence of random events. From 0 to 1 is used to express the value. To forecast how likely occurrences are to occur, probability has been introduced in mathematics. The degree to which something is likely to happen is essentially the definition of probability. This is the fundamental theory of probability, which is also applied to the probability distribution, and from which you will discover the likelihood of results for a random experiment. We must first determine the total number of outcomes in order to calculate the probability that a single event will occur.To learn more about probability, refer:

The distance between the side AB are 314.2 ft.
In a triangle ABC AC = 200 ft, m ∠A = 72°, and m ∠B = 37°. we need to find the measure of the side AB,
So,
Using sine law.
Sin A / CB = Sin B / AC = Sin C / AB
Using the angle sum property of a triangle we find the value of angle C,
∠C = 180° - (∠A + ∠B)
∠C = 180° - (72° + 37°)
∠C = 180° - 109°
∠C = 71°
So,
Sin 37° / 200 = Sin 71° / AB
AB = 200 / Sin 37° × Sin 71°
AB = 314.2 ft
Hence the distance between the side AB are 314.2 ft.

Interest earned on $25,000 when it is compounded annually for 2 years at the rate of 4.7% is $2,405.23.
What is compounding interest?Compound interest is the term for interest that is earned on interest.
This may be shown using simple math: if you start with $100 and it earns 5% interest every year, you will have $105 at the end of the first year.
At the end of the second year, you will have $110.25.
So, we know that:
Principal amount = $25000
Interest rate = 4.7%
Time = 2 years
Compounded annually
Then, using the compounding calculator:
(Refer to the graph attached below)
The amount after 2 years will be $27,405.23.
Interest in this is:
$27,405.23 - $25,000
$2,405.23
Therefore, interest earned on $25,000 when it is compounded annually for 2 years at the rate of 4.7% is $2,405.23.

Volume is the amount of space an object takes up. ___True ___False Calculate for the volume of solid. 3. Chona is selling Pringle Chips to raise money for a field trip. The container has a diameter of 9 inches and a height of 32 inches. 4. A 3-tier cake with the same height of 10 in and radius of 12 in, 8 in, 5 in respectively is to be delivered to a birthday party. How much space does this cake take up? Use 3.14 for π. 5. A Styrofoam model of a volcano is in the shape of a cone. The model has a circular base with a diameter of 48 centimeters and a height of 12 centimeters. Find the volume of foam in the model to the nearest tenth. Use 3.14 for π.
3. The volume of the Pringle Chips container is approximately 2034.72 cubic inches.
4. The cake takes up approximately 7317 cubic inches of space.
5. The volume of foam in the model of the volcano is approximately 7234.08 cubic centimeters.
1. The units for Volume are always cubed.
2. Volume is the amount of space an object takes up. True.
3. To calculate the volume of the Pringle Chips container, we need to find the volume of a cylinder. The formula for the volume of a cylinder is V = πr^2h, where π is a constant (approximately 3.14), r is the radius, and h is the height. Given that the diameter is 9 inches, the radius would be half of that, which is 4.5 inches. Substituting the values into the formula, we have:
V = 3.14 * (4.5)^2 * 32
V = 3.14 * 20.25 * 32
V ≈ 2034.72 cubic inches
4. To find the volume of the 3-tier cake, we need to find the volume of each tier separately and then add them together. Since all the tiers are cylinders, we can use the formula V = πr^2h.
Tier 1:
V1 = 3.14 * (12)^2 * 10 = 4521.6 cubic inches
Tier 2:
V2 = 3.14 * (8)^2 * 10 = 2010.4 cubic inches
Tier 3:
V3 = 3.14 * (5)^2 * 10 = 785 cubic inches
Total volume:
Total V = V1 + V2 + V3
Total V = 4521.6 + 2010.4 + 785
Total V ≈ 7317 cubic inches
5. To find the volume of the Styrofoam model of the volcano, we can use the formula for the volume of a cone, V = (1/3)πr^2h. Given that the diameter is 48 centimeters, the radius would be half of that, which is 24 centimeters. Substituting the values into the formula, we have:
V = (1/3) * 3.14 * (24)^2 * 12
V = (1/3) * 3.14 * 576 * 12
V ≈ 7234.08 cubic centimeters

Answer:
Step-by-step explanation:
10400
Answer:
3200 cm^3
Step-by-step explanation:
1. Calculate the sides of the right triangle to get the height
We know that side c = 26 and the shortest leg is 10 cm (20cm/2) because this right triangle splits the 20cm in two)
\(10^{2} + b^{2} = 26^{2} \\100 + b^{2} = 676\\b^{2} = 576 \\b = \sqrt{576} \\b = 24\)
a = 10, b = 24, c = 26
2. Use the formula for the volume of a square pyramid now that you have the height (which is b)
\(V = a^{2} \frac{h}{3} \\\\V = 20^{2} * \frac{24}{3} \\V = (400)(8)\\V = 3200 cm^{3}\)

Find an expression for the n-th term (t_(n)) in each sequence.
A). 1,(1)/(2),(1)/(3),(1)/(4),(1)/(5),(1)/(6),...
B). 3,9,15,21,27,....
Answer:
A) (1)/(7)
B) 33
Step-by-step explanation:
For (A), the sequence follows in 1 divided by numbers in a consecutive order, therefore after (1)/(6), the next term is (1)/(7)
For(B), the sequence follows in multiples of three but skips one in between
Example: Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36...
In the sequence, 6, 12, 18 and 24 are skipped, meaning that the next number to be skipped is 30, hence 33 is the next number in the sequence.
Because all the numbers in the sequence are odd numbers we can say that the sequence follows in odd consecutive numbers which are multiples of 3.

What is the distance between the points (7,5) (4,9)
The Distance will be 5.
The distance between two points is the length of the line segment connecting the two points on the plane. The formula for finding the distance between two points is usually d=√((x2 – x1)² + (y2 – y1)²). This formula is used to find the distance between any two points on the coordinate or x-y plane.
Let point (7,5) be A and point (4,9) be B
Distance formula =
Ab = √(x1- x2) ² + (y1 -y2) ²
Then Distance AB will be
Ab = √(7-4) ² + (5 -9) ²
= √ 3² + 4²
= √ 9 + 16
