Answer:
The y-intercept is - 372 and it means that if the manufacturers do not produce and sell any blenders they will have a loss of $ 372.Explanation:
The polynomial that represents the function is:
[tex]P(x)=8x+0.3x^2-0.0013x^3-372[/tex]Where the variable, x, represents the number of blenders produced and sold monthly, and P(x) is the monthly profit in dollars obtained for the sale of x blenders.
As for the question, the y-intercept is the point on the graph where the function crosses the y-axis, i.e. where the input of the function is x = 0.
Therefore, the y-intercept is the value of the function for x = 0, P(0), and it is found by substituting 0 for x in the polynomial function, which is shown next:
[tex]P(0)=8(0)+0.3(0)^2-0.0013(0)^3-372=-372[/tex]The meaning of this value is that the firm loses $372 when it does not produce and sell any blenders.
sin x= 1.5
value of x
Answer:
x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z
or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z
Step-by-step explanation:
Solve for x:
sin(x) = 1.5
1.5 = 3/2:
sin(x) = 3/2
Take the inverse sine of both sides:
Answer: x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z
or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z

What is 0.3 divided 0.24 doing long division
Answer:
1.25
Step-by-step explanation:
Change 0.3 and 0.24 into whole numbers. So this would be 30 and 24. You do 30/24 and simplify it to 5/4 (because you divide 6; both numerator and denominator) which gives you 1.25.
Final answer:
Detailed explanation on dividing 0.3 by 0.24 using long division.
Explanation:
Dividing 0.3 by 0.24 using long division:
First, insert a decimal point after 0.3 to make it 0.30.
Then, perform long division: 0.30 ÷ 0.24 = 1 remainder 0.06.
Bring down another zero to continue dividing: 0.06 ÷ 0.24 = 0.25.

If a person walks 2.4 miles in 1.5 hours, how far can he walk in 3 hours?
2.4 miles
6.2 miles
4.8 miles
Answer:
The answer is 4.8
Step-by-step explanation:
The answer is 4.8 because 1.5h is half of 3 hours so if he walks 3.0m (which is double the first amount he walked) the answer will double.
so 2.4+2.4 = 4.8
or 2.4x2 = 4.8

-3(y+3)=2y+3
help plzs!!!!!!......
Answer:
For the given expression -3( y + 3 ) = 2 y + 3 the value of y = -2.4.
Step-by-step explanation:
Here, the given expression to be simplified : -3( y + 3 ) = 2 y + 3
Now, by DISTRIBUTIVE PROPERTY:
A (B +C) = AB + AC
Simplifying the given expression:
-3( y + 3 ) = 2 y + 3 ⇒ -3 ( y) - 3 ( 3) = 2 y + 3
or, -3y - 9 = 2y + 3
⇒ 3 y + 2 y = -3 - 9
or, 5 y = -12 ⇒ y = -12/5 = -2.4
⇒ y = - 2.4
Hence,for the given expression -3( y + 3 ) = 2 y + 3 the simplified value of y = -2.4

Answer:
10) Supplementary; 11) Supplementary; 12) Complementary
Step-by-step explanation:
Sum of supplementary angles equals 180° while sum of complementary angles equals 90°.
For question 10
x + 70° = 180° (sum of straight lines)
x = 180° - 70° = 110°
Hence, 70° and 110° are supplementary angles.
For question 11,
x + 85° = 180° (sum of straight lines)
x = 180° - 85° = 95°
Hence, 85° and 95° are supplementary angles.
For question 12,
x + 32° = 90° (sum of right angles)
x = 90° - 32° = 58°
Hence, 32° and 58° are complementary angles.

Answer:
50
Step-by-step explanation:
200/2=100
100/2=50
A quarter of something is just another word for a fourth of something (1/4th).
We can solve this using two different ways.
Solution #1:
1/4 = 0.25
200 * 0.25 = 50 (quarter of 200)
Solution #2:
200 / 4 = 50 (quarter of 200)

PLEASE HELPPPP ! 16^x=64^x+4
Answer:
x = -12
Step-by-step explanation:
Set logs up on both sides-
log 16^x = log 64^x+4
The variable goes behind because of the exponent log property (exponents are permitted to go behind the log to multiply)-
x * log 16 = x + 4 * log 64
Divide both logs out-
log 64/log 16 = 1.5
Simplify-
x = x+4(1.5)
1.5x + 6 = x
Remove 1.5-
1 - 1.5 = -.5x
Simplify-
-.5x = 6
Divide both sides-
6/-.5x = -12
Hence, the answer would be -12
A sequence has a common ratio of Three-halves and f(5) = 81. Which explicit formula represents the sequence? f(x) = 24(Three-halves) Superscript x minus 1 f(x) = 16(Three-halves) Superscript x minus 1 f(x) = 24(Three-halves) Superscript x f(x) = 16(Three-halves) Superscript x
Answer:
[tex]f(x)=16\, (\frac{3}{2} )^{x-1}[/tex]
Step-by-step explanation:
Since we are given the common ratio (3/2), all we need to find to define the geometric sequence, is its multiplicative factor ([tex]a[/tex]) that corresponds to the first term of the sequence - remember that all consecutive terms will be generated by multiplying this first value repeatedly by the common ratio (3/2) as shown below:
[tex]f(1)=a\\f(2)=a\,*\,(\frac{3}{2} )\\f(3)=a\,*\,(\frac{3}{2} )^2\\f(4)=a\,*\,(\frac{3}{2} )^3\\f(5)=a\,*\,(\frac{3}{2} )^4[/tex]
Since we are given the information that [tex]f(5)=81[/tex] we can use this to find the value of the first term:
[tex]f(5)=\,a\,*\,(\frac{3}{2} )^4\\81=\,a\,*(\frac{81}{16} )\\a\,*\,81=\,81\.*\,16\\a\,=\,16[/tex]
Notice as well that the first term doesn't contain the common ratio, the second term contains the common ration (3/2) to the power one, the third one contains the common ratio to the power two, the fourth one contains it to the power three, and so forth. So the exponent at which the common ratio appears is always one unit less than the order (x) of the term in question. This concept helps us finalize the expression for the sequence's formula:
[tex]f(x)=16\,*\,(\frac{3}{2} )^{x-1}[/tex]

A piece of cloth costs 200$.if the piece was 5m longer, and the cost of each metre of clth was 2$ less, the cost of the piece would have remained unchanged. How long is the piece and what is its original number of persons.
Answer:
20 m long,
each piece of cloth for $10
Step-by-step explanation:
Let x m be the length of the piece of cloth.
Original cloth:
Length = x m
Cost = $200
Cost per meter [tex]\dfrac{\$200}{x}[/tex]
Changed cloth:
Length = x + 5 m (5 m longer)
Cost = $200
Cost per meter [tex]\dfrac{\$200}{x}-\$2[/tex] (each metre of cloth was $2 less)
Hence,
[tex]\left(\dfrac{200}{x}-2\right)\cdot (x+5)=200[/tex]
Multiply the equation by x:
[tex](200-2x)(x+5)=200x\\ \\200x+1,000-2x^2-10x=200x\\ \\-2x^2-10x+1,000=0\\ \\x^2+5x-500=0\\ \\D=5^2-4\cdot(-500)=25+2,000=2,025\\ \\x_{1,2}=\dfrac{-5\pm\sqrt{2,025}}{2}=\dfrac{-5\pm 45}{2}=-25,\ 20[/tex]
The length cannot be negative, so x = 20 m, each metre for $10.
Answer:
The piece is 20 m long and costs $10 per meter
Step-by-step explanation:
The total cost of the cloth in $ can be expressed as
C = xu
Where x is the length of the cloth in m, and u is the unit cost in $/m
The problem states that if the length was 5 meters more and the unit cost was $2 less, the cost would not change, that is
C = (x+5)(u-2)
Operating:
C = xu-2x+5u-10
Since C = xu, then
-2x+5u=10 [1]
We also know that
xu=200 [2]
Isolating u in [1] we get
[tex]u=\frac{10+2x}{5}[/tex]
Replacing into [2]
[tex]x\frac{10+2x}{5}=200[/tex]
Simplifying
[tex]10x+2x^2=1000 \\=> x^2+5x-500=0[/tex]
Factoring
(x-20)(x+25)=0
Which gives x=20, x=-25. We can only use the positive value of x, so
x=20 m and therefore
u=200/20=10$
So the piece is 20 m long and costs $10 per meter
Your company takes orders over the phone. The company’s average time is 4.6 minutes.The graph below shows 4 calls and the difference between the call time and the company’s average call time.
Answer:
0.4
Step-by-step explanation:
The mean difference between the call will be 0.4. Then the correct option is C.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
Your company takes orders over the phone. The company’s average time is 4.6 minutes. The graph below shows 4 calls and the difference between the call time and the company’s average call time.
Then the mean difference between the call will be
Mean = (Sum of the observation) / (Number of the observation)
Mean = (-2.32 - 1.55 + 4.79 + 0.68) / 4
Mean = 1.6 / 4
Mean = 0.4
The mean difference between the call will be 0.4. Then the correct option is C.

57 first-year teachers and 19 experienced teachers attended a school staff meeting meeting. What percentage of the teachers in the meeting were first-year teachers?
Write your answer using a percent sign (%).
Answer:
75%
Step-by-step explanation:
57 / (57+19) = 0.75
Final answer:
About 75% of the teachers in the meeting were first-year teachers, as calculated by dividing the number of first-year teachers by the total number of teachers and then multiplying by 100.
Explanation:
To determine what percentage of the teachers in the meeting were first-year teachers, we use the formula 'part over total, times one hundred, equals percent'. In this scenario, the 'part' is the number of first-year teachers which is 57, and the 'total' is the sum of first-year and experienced teachers, which is 57 + 19 = 76. The calculation then becomes 57/76 times 100, to find that percentage.
Carrying out the calculation:
(57 / 76) times 100 = 0.75 times 100 = 75%
Therefore, approximately 75% of the teachers at the meeting were first-year teachers.

A gardener at a nursery is filling pots with soil to prepare to
transplant seedlings into these larger pots. Each new pot needs about 27 cubic inches
of soil. The amount of soil s (in cubic inches) it takes to fill p pots is given by the
function s = 27p
a.
The gardener is filling the pots from a bag of soil that contains 3456 cubic
inches of soil. How many pots can be filled from the bag?
b.
Suppose the gardener needs to fill at most 109 pots. How much soil (in cubic
inches) will the gardener need?
Answer:
a. 127 pots
b. 2,943 cubic inches
Step-by-step explanation:
To find the amount of pots of soil can be filled, you can use the equation given. s = 3456 in part a
a.
s = 27p
3456 = 27p
divide 3456 by 27 to isolate p
p = 127 pots
Instead of substituting for s like in part a, you can now substitute for p, since you know that you need to fill 109 pots.
b.
s = 27 * 109
s = 2943 cubic inches
The gardener can fill 128 pots with the 3456 cubic inches of soil available. If the gardener needs to fill at most 109 pots, they will require 2943 cubic inches of soil.
To solve both parts of the question, we will use the function s = 27p, where s represents the amount of soil (in cubic inches) and p represents the number of pots.
Part a: Calculating the Number of Pots
The gardener has a bag containing 3456 cubic inches of soil. To find out how many pots can be filled from the bag, we need to divide the total amount of soil by the amount needed per pot:
p = 3456 cubic inches / 27 cubic inches per pot = 128 pots
Part b: Soil Needed for a Maximum Number of Pots
If the gardener needs to fill at most 109 pots, the total amount of soil required can be calculated using the provided function:
s = 27 cubic inches per pot * 109 pots = 2943 cubic inches of soil

A. It would be needed 20 packets to transmit 30,000 bytes of information and B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.
Step-by-step explanation:
1. Let's review the information provided to us for solving the question:
Size of each packet of information = 1,500 bytes
Number of packets = P
Number of bytes of information = B
2. Let's answer the questions:
A. How many packets would be needed to transmit 30,000 bytes of information?
P = 30,000 ÷ 1,500
P = 20
It would be needed 20 packets to transmit 30,000 bytes of information
B. How much information could be transmitted in 30,000 packets?
B = 30,000 * 1,500
B = 45'000,000
45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.
