The height of an object launched upward from ground level is given by the function s(t) = -4.9t2 + 78.4t, where s(t) is the height in meters and t is the time in seconds. Arrange the time intervals in ascending order of the object's magnitude of average velocity over the interval.
Answer:
the distance of the object before it hits the ground after launch is t = 1.592 seconds
Step-by-step explanation:
The height of an object launched upward from ground level is given by the function s(t) = -4.9t² +7.8t
when the object reach the ground then s(t) = 0
So; -4.9t² +7.8t = 0
-4.9t² +7.8t + 0 = 0
By using the quadratic equation
[tex]\mathbf{\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}}[/tex]
where; a = -4.9 ; b = 7.8 and c = 0
[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(7.8)^2-4(-4.9)(0)} }{2(-4.9)}}[/tex]
[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(60.84} }{-9.8}}[/tex]
[tex]\mathbf{=\dfrac{-(7.8) + \sqrt{(60.84} }{-9.8} \ \ \ \ OR \ \ \ \ \mathbf{\dfrac{-(7.8) - \sqrt{(60.84} }{-9.8}}}[/tex]
[tex]\mathbf{=0 \ \ \ OR \ \ \ 1.592 }}[/tex]
Hence; the distance of the object before it hits the ground after launch is t = 1.592 seconds

Yasmin is measuring wood to make picture frames.She needs 9/10 meters of wood for on frame.She needs 35 centimeters less wood for a second frame.How many centimeters of wood will Yasmin need for the second frame?
Answer: 55 cm
Step-by-step explanation:
Hi, to answer this question, first, we have to convert the meters into centimeters.
Since: 1 m = 100 cm
We have to multiply the length of the first frame by 100 to express the length in cm.
9/10 m x 100cm/m = 90 cm
Finally, since she needs 35 centimeters less wood for a second frame, we have to subtract 35 cm to the amount of woof needed for the first frame.
90-35 = 55 centimeters.

Lines AB and CD are parallel. If 2 measures (3x - 33)°, and 4 measures 147°, what is the value of x?
Given: m∠ABC = 50°,
AC = 30
Find: OA
Answer:
OA = 19.58
Step-by-step explanation:
If we draw the segments OA and OC, we will have an isosceles triangle OAC.
With the property of inscribed angles and central angles that are related to the same arc of the circunference, we have:
mAOC = 2 * mABC
mAOC = 2 * 50 = 100°
As the triangle OAC is isosceles, we have that mOAC = mACO.
Knowing that the sum of internal angles of a triangle is 180°, we have:
mACO + mOAC + 100 = 180
2 * mACO = 80
mACO = 40°
Now, using the law of sines, we have:
OA / sin(ACO) = AC / sin(AOC)
OA / 0.6428 = 30 / 0.9848
OA = 30.463 * 0.6428 = 19.58

There are 2,010 Starbucks in California. The population of California is 38.8 million. Which of
the following best represents the Starbucks per capita in Scientific Notation?
1.93 x 104
5.18 x 10-4
51.8
5.18 x 10-5
Answer:
5.18x10-5 is the correct answer
Step-by-step explanation:
Scientific notations are used to represent relatively large and small numbers.
The population per capita is (d) [tex]5.18 \times 10^{-5}[/tex]
The populations are given as:
[tex]Starbucks = 2010[/tex]
[tex]People = 38.8\ million[/tex]
The population of Starbucks per capita is calculated by dividing the population of Starbucks by the population of the people.
So, we have:
[tex]Per\ Capita = \frac{Starbucks}{People}[/tex]
Substitute known values
[tex]Per\ Capita = \frac{2010}{38.8\ million}[/tex]
Divide
[tex]Per\ Capita = 0.00005180412[/tex]
Approximate
[tex]Per\ Capita = 0.0000518[/tex]
Express as scientific notation
[tex]Per\ Capita = 5.18 \times 10^{-5}[/tex]
Hence, the population per capita is (d) [tex]5.18 \times 10^{-5}[/tex]

Katrina is asked to simplify the expression Negative 3 a minus 4 b minus 2 (5 a minus 7 b).
She writes: Negative 3 a minus 4 b minus 2 (5 a minus 7 b) = negative 3 a minus 4 b minus 10 a + 14 b
Which property allows her to do this?
the associative property
the commutative property
the distributive property
the additive identity property
Answer:
Distributive property
Step-by-step explanation:
Distributive property allows you to multiply a(b+c) as ab + ac.
The property which allows her to do this solution is; Distributive property
What is distributive property?The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is
A(B + C) = AB + AC
This property is known by distributive law and applies to subtraction also.
We are given that Katrina is asked to simplify the expression Negative 3 a minus 4 b minus 2 (5 a minus 7 b).
She writes:
= -3 a - 4 b - 2 (5 a -7 b)
= - 3 a - 4 b -10 a + 14 b

Predict how many times you will roll a number less than 5 if you roll a standard number cube 350 times. Round to the nearest integer, if necessary.
Answer:
233 Times
Step-by-step explanation:
In a standard cube, there are 6 faces labelled 1 to 6.
Numbers less than 5=1,2,3,4
The probability of rolling a number less than 5 =4/6
Therefore, if the standard number cube is rolled 350 times.

Answer:
x = 0.09
Step-by-step explanation:
Use the pythagorean theorum.
a^2 + b^2 = c^2
Plug in the values.
a^2 + 0.4^2 =0.41^2
= a^2 + 0.16 = 0.1681
Subtract to get a (which is the x value)
a^2 = 0.1681 - 0.16
a^2 = 0.0081
Square root 0.0081 to get a.

To find the slope or the cost per pound of hamburger you divide 8.97 by 5 in order to find out it costs 2.99 per hamburger. You then, multiply 2.99 by 5 to gather that to buy 5 pounds of hamburger it would cost $14.95.
The table shows six random samples from two corn fields that were fertilized with two different types of fertilizers. Based on the
mean of the data sets, which statement is true?
Fertilizer A produced a 5% greater yield
Fertilizer B produced a 5% greater yield
Fertilizer A produced a 24% greater yield
Fertilizer B produced a 24% greater yield
Answer:
Step-by-step explanation:
fertilizer b produced a 24% greater yield
mean yield fertilizer a = 20.5
mean yield fertilizer b = 25.5
thus,
25.5 − 20.5
20.5
= 0.2439 ≈ 0.24 or 24%
Answer: D Where B produced 24% greater yield is the Answer.
Step-by-step explanation:
B produced a 24% greater yield as 24% of 25 = 4
4 is found when we deduct it from B to find A as smaller.
A= 122.90/6=20.48 mean
B =152.1/6 = 25.35 mean
