Answer:
x (distance) = 10, max height = .75
Step-by-step explanation:
y=-.03x(x-10)
The distance are the x intercepts: 0 and 10, where 0 is time started and 10 is time ended.
Expand the equation:
y=-.03x^2 +.3x
To find max height you find the vertex
x = -b/2a
x = -.3/-.06 = 5
Plug the x into the equation
y=.-03(5)^2 +.3(5)
y=.75
Some equations have the form y=kxy=kx, where kk is a number.
Which equation CANNOT be written in the form y=kxy=kx?
Answer:
[tex]x = 4y[/tex]
Step-by-step explanation:
Given
[tex]y = kx[/tex]
See attachment for options.
Required
Determine which of the options answers the question
Analyzing the option one after the other:
[tex]\frac{x}{y} = 4[/tex]
Multiply through by y
[tex]y * \frac{x}{y} = 4 * y[/tex]
[tex]x = 4y[/tex]
Divide through by 4
[tex]\frac{x}{4} = \frac{4y}{4}[/tex]
[tex]\frac{x}{4} = y[/tex]
This can be rewritten as
[tex]y = \frac{x}{4}[/tex]
[tex]y = \frac{1}{4} x[/tex]
By comparison with [tex]y = kx[/tex]
we have:
[tex]y = y[/tex]
[tex]x = x[/tex]
[tex]k = \frac{1}{4}[/tex]
Hence: this answers the question.

On a certain planet, Continent X has an area of 6.23*10^6 square miles and Continent Y has an area of 63,600,000 square miles. How many times larger is Continent Y than Continent X?
Answer:
Step-by-step explanation:
Continent X =6.23*10^6
Continent Y= 63,600,000
rounded = 60,000,000
Scientific notation = 6*10^7
Now round continent X= 6.23 or 6
Continent X= 6*10^6
6*10^7/ 6*10^6 = 1*10^(7-6)
= 1*10^1
= 1*10
= 10
So your answer would be 10.
I hope that helps
Answer:
Step-by-step explanation:Continent X =6.23*10^6
Continent Y= 63,600,000
rounded = 60,000,000
Scientific notation = 6*10^7
Now round continent X= 6.23 or 6
Continent X= 6*10^6
6*10^7/ 6*10^6 = 1*10^(7-6)
= 1*10^1
= 1*10
= 10
So, your answer would be 10 I would have done it this way too not trying to copy(:

Katherine wants to prove that the measures of the interior angles of a triangle have a sum of 180' She draws a triangle and extends one of the sides through a vertex. She then draws a line through th
Vertex thai paralel to the opposite side as shown in the diagram below
Answer:
The statements that must be true are;
A. m∠1 = m∠5
B. m∠2 = m∠4
C. m∠3 + m∠4 + m∠5 = 180°
Step-by-step explanation:
The given parameters are;
The fact Katherine wants to prove = The sum of the measures of the interior angles of a triangle = 180°
The line Katherine drew passing through the vertex = Parallel to the opposite side of the triangle
Therefore we have;
1) m∠1 and m∠5 are corresponding angles and m∠1 = m∠5 for corresponding angles of parallel lines having the same transversal
2) m∠2 and m∠4 are alternate interior angles and m∠2 = m∠4 for alternate interior angles of parallel lines having the same transversal
3) m∠3 and m∠4 and m∠5 are angles on a straight line and angles on a straight line are supplementary
∴ m∠3 + m∠4 + m∠5 = 180°, by the definition of supplementary angles
Therefore, m∠3 + m∠2 + m∠1 = 180° (substitution property)
m∠3 + m∠2 + m∠1 = Sum of interior angles of a triangle = 180°.

in Haritha haram,108,84 and 60 saplings of mango guava and sapota are supplied .find the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted
Answer: 21
Step-by-step explanation:
Given: Number of mango guava and sapota are supplied 108,84 and 60 respectively.
Since, 108 = 2 x 2 x 3 x 3 x 3
84 = 2 x 2 x 3 x 7
60 = 2 x 2 x 3 x 5
HCF(108,84,60) = 2 x 2 x 3 [HCF=Highest common factors]
= 12
Greatest number of plants in each row = 12
Number of rows for mango = [tex]\dfrac{108}{12}=9[/tex]
Number of rows for guava = [tex]\dfrac{84}{12}=7[/tex]
Number of rows for sapota = [tex]\dfrac{60}{12}=5[/tex]
Total rows = 9+7+5= 21
Hence, the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted = 21

Point M is on line segment overline LN . Given MN = 3x , LN = 4x + 9 , and LM = 2x + 7 determine the numerical length of LM .
Answer: 11
Step-by-step explanation:just trust me
The numerical length of LM will be 11.
It is given that point M is on line segment overline LN . Also , MN = 3x , LN = 4x + 9 , and LM = 2x + 7.
We have to determine that what will be the numerical length of LM ?
What will be the value of x in equation ; 3x + 2 = 8 ?
The value of x will be 2.
From the question we can get that ,
MN + LM = LN
2x + 7 + 3x = 4x + 9
5x + 7 = 4x + 9
x = 2
Now , we can use the value of x to find out length of LM ;
∵ LM = 2x + 7
⇒ LM = 2 × 2 + 7
⇒ LM = 11.
Thus , the numerical length of LM will be 11.

On June 19, NoteQuest Inc. instituted a 3-for-2 split. At that time Keisha owned 205 shares of that stock. The price per share was
$33.99. After the split, Keisha received a check for a fractional part of a share. What was the amount of that check?
Answer:
$11.33
Step-by-step explanation:
Keisha will own 307 shares after the split. and the amount of check is 11 dollar.
Given that, NoteQuest Inc. instituted a 3-for-2 split. At that time Keisha owned 205 shares of that stock. The price per share was
$33.99.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here, 3+ 2 = 5
Now, let x be the number of shares post split
Then;
3/2 = x/205
x = 3/2 (205)
x = 615/2 = 307.5
Therefore, Keisha will own 307 shares after the split.
