Write the standard form of the line that contains a slope of 12 and y-intercept of 3. Include your work in your final answer.
Answer:
y = 12x+3
Step-by-step explanation:
y = mx+c
m is the gradient/slope
c is the y intercept
so m is 12 and c is 3
I need this answered ASAP. A baseball hit by

Which table represents a quadratic relationship?
The table which represents a quadratic relationship is in option [tex]D[/tex].
What is quadratic relationship ?A quadratic relationship is a mathematical relation between two variables that follows the form of a quadratic equation.
Quadratic sequence [tex]=an^2 +bn+c[/tex]
So, According to the definition mentioned above if table follows the form of a quadratic equation then it is in quadratic relationship.
So,
To find out quadratic relationship,
We will find first difference in every table and then second difference (Second difference is the difference between the first difference).
We have,
Table A;
[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &4&2-4=-2\\-1& &2&1-2=-1&-1+2=1\\0& \ &1&0.5-1=-0.5&-0.5+1=0.5\\1& &0.5&0.25-0.5=-0.25&-0.25+0.5=0.25\\2& &0.25&0.125-0.25=-0.125\\3& &0.125\end{array}\right[/tex]
So, In the above table we can see that second difference is not equal that means it is not in quadratic relationship.
Now,
Let Table D;
[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &-23.4&\\-1& &-23.2&-23.2+23.4=-0.2&0.2-0.2=0\\0& \ &-23&-23+23.2=-0.2&0.2-0.2=0\\1& &-22.8&-22.8+23=-0.2&0.2-0.2=0\\2& &-22.6&-22.6+22.8=-0.2\\3& &-22.4&-22.4+22.6=-0.2\end{array}\right[/tex]
So, here in this table, we can see that second difference is equal that means it is in quadratic relationship.
Hence, we can say that the table which represents a quadratic relationship is in option [tex]D[/tex].

If each of the numbers in the following data set were multiplied by 18, what
would be the new median of the data set?
14, 20, 18, 58, 71, 36, 28
what would be the new median of the data set ?
The answer is 28 or 504. My explanation....
ALRIGHT! So, it took me a little while to do it all.... since I wasn't really sure if it was already multiplied by 18 or not.
So the normal numbers in order from least to greatest,(because that's easier)
14, 18, 20, 28, 36, 58, 71.
The new numbers I multiplied by 18 are...
252, 324, 360, 504, 648, 1044, 1268.
When I put it like that you can clearly see the new median. 28 and 504!

tell whether the sequence is arithmetic if it is what is the common difference?
19, 12, 5, -2
no
yes; 1/7
yes;7
yes;-7
Answer:
(d) yes; -7
Step-by-step explanation:
The differences between terms are ...
12 -19 = -7
5 -12 = -7
-2 -5 = -7
These are all the same, so this difference is "common". A sequence in which terms have a common difference is an arithmetic sequence.
This sequence is arithmetic, with a common difference of -7.

HELP ME FIND MIDPOINT
Answer: (-1/2, 0) which is the same as saying (-0.5, 0)
================================================
Explanation:
The x coordinates of A and B are -2 and 1 respectively.
Add up those values to get -2+1 = -1
Then cut that result in half: -1/2 = -0.5
This is the x coordinate of the midpoint.
--------
Repeat for the y coordinates:
Add: 1 + (-1) = 0
Cut in half: 0/2 = 0
The y coordinate of the midpoint is 0
-------
Overall, the midpoint is located at (-1/2, 0) which is the same as writing (-0.5, 0). This is where the segment AB crosses the x axis.

What is the measure of angle PBQ
Answer:
m∠PBQ=51
Step-by-step explanation:
By vertical angles theorem, ∠PBQ ≅ ∠LBM, so m∠PBQ=m∠LBM.
And since ∠LBM & ∠LBQ are supplementary, we'll write,
m∠LBM+LBQ=180°
3x+(4x+61)=180°
Let's solve for x:
7x=119
7x/7=119/7
x=17
So...
m∠LBM=3(17)
m∠LBM=51
This means that m∠PBQ=51

Answer:
x = 19.Step-by-step explanation:
We have to simplify this equation.
Like this:
2 * x + 8 = 46.The closest number to x is 19:
2 * 19 + 8 = 46Solve:
2 * 19 + 8 = 46= 38 + 8 = 46= 46.x = 19.

Find the area of the semicircle.
Either enter an exact answer terms of ar or use 3.14 for at and enter your answer as a decimal.
units2
Answer: 39.25
========================================
Work Shown:
d = diameter = 10
r = radius = d/2 = 10/2 = 5
A = area of a full circle
A = pi*r^2 = 3.14*5^2 = 78.5
Cut this in half to get the area of a semicircle (aka half circle)
(78.5)/2 = 39.25
This result is approximate.
