Answer:
y = 3(x + 1)^2 - 8Step-by-step explanation:
Given
y = 3x^2 + 6x – 5Converting to vertex form
y = a(x – h)^2 + ky = 3x^2 + 6x + 3 - 8y = 3(x + 1)^2 - 8What is the sum of the first 50 terms of the series 2 + 17 + 32 + 47+ ...?
Answer:
[tex]\huge\boxed{18,475}[/tex]
Step-by-step explanation:
The terms of this sum make the arithmetic sequence.
The fomula of a sum of n terms of an arithmetic sequence:
[tex]S_n=\dfrac{[2a_1+(n-1)d]\cdot n}{2}[/tex]
We have
[tex]a_1=2\\d=17-2=32-12=47-32=15\\n=50[/tex]
Substitute:
[tex]S_{50}=\dfrac{[2\cdot2+(50-1)\cdot15]\cdot50}{2}=(4+49\cdot15)\cdot25=(4+735)\cdot25\\\\=739\cdot25=18,475[/tex]

Step-by-step explanation:
Kai took five tests this semester. His scores are listed below.
92, 88, 90, 96, 84
What is the mean absolute deviation of Kai's test scores?
Answer: 16
Step-by-step explanation:
Find the mean absolute deviation of the data:
X : 92, 88, 90, 96, 84
Find the mean(m) of the data:
m = Σ(X) / n
n = number of samples
(92 + 88 + 90 + 96 + 84) / 5
m = 450 / 5
m = 90
Absolute Deviation of each value of the mean:
|x - m| :
|92 - 90| = 2
|88 - 90| = 2
|90 - 90| = 0
|96 - 90| = 6
|84 - 90| = 6
Σ|x - m| = 2 + 2 + 0 + 6 + 6 = 16

Find X to complete the following ratio. 12:5 = 24:X
Answer:
x = 10
Step-by-step explanation:
This is the answer because:
1) 12:5 is equivalent to the ration 24:10
2) This is because to get 24 you have to multiply 12 and 2 which is 24
3) Next, you have to do the same to the other side to make everything equal. Therefore, you have to multiply 5 with 2 which is 10.
4) Finally, your answer should be 24:10
Hope this helps! :D
Find the slope of the line that passes between the points (4, 3/8) and (6, 7/8)
Answer:
1/4
Step-by-step explanation:
We have two points, so we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7/8 - 3/8 ) / ( 6-4)
= ( 4/8) /2
= 1/2 / 2
= 1/4

For the function h(x) = 9 + 6x , what is the domain of function h if the range is {-12, -3, 15, 24}? TIMED!WILL GIVE BRANLIEST!
A. {−3.5, −2, 1, 2.5}
B. {−3, 6, 24, 33}
C. {−63, −9, 99, 153}
D. {−0.5, 1, 4, 5.5}
Answer:
A. {−3.5, −2, 1, 2.5}
Step-by-step explanation:
Remember that the range is the possible values for Y in any given function, so in this case, we are given the Y values and we have to solve the function for x:
y=9+6x
6x=y-9
[tex]x=\frac{y-9}{6}[/tex]
So we just insert the values, the first one being -12.
[tex]x=\frac{y-9}{6}\\x=\frac{-21}{6}\\x=\frac{-12-9}{6}\\x=-3.5[/tex]
So since from the options only A has -3.5 as an option that's the correct answer.
1/x-x/6=2/3 how to answer this
Answer:
x = 0.1
Step-by-step explanation:
1/x - x/6 = 2/3
1/ x - 6/x = 2/3
6/x = 2/3
6x = 2/3
x = 0.1
Answer:
x = 0.2
Step-by-step explanation:
1/x - x/6 = 2/3
=> 1/x - x = 2/3 * 6
=> 1/x - x = 12/3
=> 1/x - x = 4
=> 1/x - x/1 = 4 (x = x/1 )
=> 1 - x/1 = 4 * x
=> -x/1 = 4x - 1
=> -x/1 -4x = -1
=> -5x/1 = -1
=> x = -1/-5
=> x = 0.2 (Because negative / negative = positive)

On a circle with radius 12 m, what angle would subtend an arc with a length of 7 m?
Answer:
33.42
Step-by-step explanation:
just trust me
33.42 angle would subtend an arc with a length of 7 m.
How do you find the angle of an arc?The angle formed by the arc at the center of the circle is the angle of the arc. Indicated by. m A B ^, A, and B are the endpoints of the arc. You can use the arc length equation to find a measure of the arc angle.
For a circle, the arc length equation is θ times the radius of the circle. The equation for arc length in radians can be expressed as Arc length = θ × r, where θ is in radians. Arc length = θ × (π / 180) × r, where θ is in degrees and L = arc length. θ = central angle of the arc.
