Answer:Nope
Step-by-step explanation:
The equation, b(t) = - 5t ^ 2 + 10t + 6, is a parabola with a vertex. We must find whether that vertex is equal to or exceeds 12m. One can graph the equation and find that the vertex is at (1,11), below the 12. It cannot reach 12 meters.
[One may also differentiate the equation and set it equal to zero (the point at which the slope of the parabola is zero, which will be at the vertex as it begins downward)].

An airline runs a commuter flight between Portland, Oregon, and Seattle, Washington, which are 145 miles apart. An increase of 20 miles per hour in the average speed of the plane decreases the travel time by 12 minutes. What initial average speed results in this decrease in travel time? (Round your answer to one decimal place.)
The speed of the airplane is the ratio of the distance to the time
The initial average speed of the airplane is approximately 110.8 mph
Reason:
Given parameters are;
The distance between Portland Oregon and Seattle Washington = 145 miles
The decrease in travel time when the speed is increase by 20 mph = minutes
The initial speed of the airplane, v = Required;
Solution;
[tex]t = \dfrac{145}{v}[/tex]
[tex]t - \dfrac{12}{60} = \dfrac{145}{v + 20}[/tex]
Therefore;
[tex]\dfrac{145}{v} - \dfrac{12}{60} = \dfrac{145}{v + 20}[/tex]
Which gives;
[tex]\dfrac{145}{v + 20} - \dfrac{145}{v} + \dfrac{12}{60} = 0[/tex]
Therefore
0.2·v² + 4·v - 2,900 = 0
v ≈ ±110.8 mph
The initial average speed of the airplane, v≈ ± 110.8 mph

Answer:
m<v= 60 degrees
m<x= 100 degrees
Step-by-step explanation:
1) First let's find the measure of angle v. Most of the time if none of the angles are known then it is impossible to find others. However, this specific triangle is an equilateral, which has special rules. We know this is an equilateral because all the sides have the same length. Equilaterals will always have angles with measures of 60 degrees. This is due to the fact that sides and angles are proportionate. Therefore, if all the sides are the same, then the angles must be as well and 180 divided by 3 is 60.
2) Then, we can find the next measurement. This triangle is isosceles. Isosceles triangles have 2 equal sides and angles. The triangle represented above has 2 congruent sides; therefore, the base triangles must also be congruent. So we know that angles Y and W are 40. To find angle X make the expression 180-(40+40). This means that angle x must be 100 degrees.
Daria bought
a skein of alpaca yarn for $47.50, a skein
of angora yarn for $32.14, a skein of wool
yarn for $16.50, and a pair of knitting
needles for $3.86. How much did she
spend in all? Describe how you calculated
your answer
The total amount Daria spent on all her purchases is $100
In order to determine the total amount Daria spent on all her purchases, the cost of each item has to be added together.
Addition is a mathematical operation that can be used to determine the total sum of two or more values. other basic mathematical operations are subtraction, multiplication and division.
Total amount spent = cost of a skein of alpaca yarn + cost of a skein
of angora yarn + cost of a skein of wool yarn + cost of a pair of knitting
needles
$47.50 + $32.14 + $16.50 + $3.86 = $100

A horse travels at about 65 kph. At this rate, how far can it travel in 20 minutes
Answer: Approximately 21.667 km
This value as a fraction is 65/3, but I think the decimal form is probably more practical in real world settings.
======================================================
Work Shown:
20 min = 1/3 of an hour, since 20/60 = 1/3. In other words, there are three chunks of 20 minutes that make up a full hour.
distance = rate*time
distance = (65 kph)*(1/3 hr)
distance = (65*1/3) km
distance = (65/3) km
distance = 21.667 km which is approximate
Answer:
Distance rate=Rate x Time
Distance= (75 km/h) 20 mins
Convert 20 mins in hours= 1/3 h
Distance= (75 km/h) (1/3 h)= 25 km.....

6 adults & 4 senior citizens have to pay $228 while 13 adults and 7 senior citizens have to pay $459 to visit an exhibition at the Art science Museum . Find the total amount 2 adults & Senior citizen have to pay to visit the exhibition.
Answer: Rs. 69
Step-by-step explanation:
Let the amount that the adults have to pay be Rs. “x” and the amount that the senior citizens have to pay be Rs. “y”.
Step 1:
According to the question, we get
Equation 1:
6x + 4y = 228
Equation 2:
13x + 7y = 459
Step 2:
Then, by multiplying equation 1 by 7 & equation 2 by 4, we get
7 * [6x + 4y = 228]
⇒ 42x + 28y = 1596 …. (iii)
And,
4 * [13x + 7y = 459]
⇒ 52x + 28y = 1836 …. (iv)
Step 3:
Now, Subtracting eq. (iii) from eq. (iv), we get
52x + 28y = 1836
42x + 28y = 1596
(-) (-) (-)
---------------------------
10 x = 240
----------------------------
⇒ x = 240/10 = 24
Substituting the value of x in Eq. (1)
(6*24) + 4y = 228
⇒ y = [228 - 144]/4 = 21
Step 4:
Thus,
The total amount that 2 adults and a senior citizen have to pay to visit the exhibition is,
= 2x + y
= (2*24) + 21 ….. [substituting x= 24 & y = 21]
= Rs. 69

Decide if the following statement is true or false. A simple random sample of twelve 2+ bedroom houses in Rockingham County has a mean monthly lease of $695 with a standard deviation of $135. The true rental cost will be from $560 to $830
Answer:
Step-by-step explanation:
783
The given statement is "False" because the statement's range is based on the mean and standard deviation of a simple random sample of houses, not the whole population of Rockingham County's houses..
What is a simple random sample?A simple random sample is a subset of a population chosen in a way that gives each member of the population an equal chance of being selected. The mean and standard deviation of a simple random sample provides information about the population from which the sample was drawn, but they do not provide a range in which the true value of a population parameter is guaranteed to fall.
In this case, the statement provides a range for the true rental cost of 2+ bedroom houses in Rockingham County, but there is no guarantee that the true rental cost will fall within this range. The range provided in the statement is based on the mean and standard deviation of a simple random sample of houses, not the entire population of houses in Rockingham County.
Hence, the given statement is False.
