PLS HELP IMMEDIATLYRewrite the equation by completing the square. 4 x^{2} +8 x +3 = 0 in (x+_)^2=_
Answers
Answer:
(x + 1)^2 = 1/4
Step-by-step explanation:
Here, we want to rewrite the equation by completing the square.
The equation to rewrite is;
4x^2 + 8x + 3 = 0
4x^2 + 8x = -3
divide through by the coefficient of x^2 which is 4
That will give ;
x^2 + 2x = -3/4
Now divide the coefficient of x by 2, square it and add to both sides of the equation.
We have;
x^2 + 2x + 1^2 = -3/4 + 1^2
x^2 + 2x + 1 = -3/4 + 1
x^2 + 2x + 1 = 1/4
= (x + 1)^2 = 1/4

what is the diamater of a circle
the area of a circle is 144π m^2
Answers
Answer:
24 meters
Step-by-step explanation:
The area of a circle can be found using the following formula.
[tex]a=\pi r^2[/tex]
We know that the area is 144pi m^2.
[tex]a= 144\pi m^2[/tex]
Substitute 144pi m^2 in for a.
[tex]144\pi m^2= \pi r^2[/tex]
We want to find the diameter. First, we must find the radius. We have to get the variable, r, by itself.
Divide both sides of the equation by pi.
[tex]144\pi m^2/ \pi = \pi r^2 / \pi[/tex]
[tex]144\pi m^2/ \pi = r^2[/tex]
[tex]144 m^2= r^2[/tex]
The variable, r , is being squared. The inverse of a square is the square root. Take the square root of both sides of the equation.
[tex]\sqrt{144 m^2} =\sqrt{r^2}[/tex]
[tex]\sqrt{144 m^2} =r[/tex]
[tex]12 m= r[/tex]
The radius of the circle is 12 meters, but the question asks for diameter. The diameter is twice the radius.
[tex]d= r*2[/tex]
The radius is 12 m.
[tex]d= 12 m*2[/tex]
Multiply
[tex]d= 24 m[/tex]
The diameter of the circle is 24 meters.

Joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are going on the trip, so they need at least 50 total rooms. Joe had already reserved and paid for 16 rooms, so he needs to reserve additional rooms. He can only reserve rooms in blocks, and each block contains 8 rooms and costs $900. Let B represent the number of additional blocks that Joe reserves. 1) Which inequality describes this scenario? 2)What is the least amount of money that Joe can spend to get the amount of rooms they need? Work not needed!
Answers
Answer:
The answer is below
Step-by-step explanation:
1) The number of rooms Joe company needs is 50. Let the number of rooms needed be n, this can be represented by the inequality:
n ≥ 50
Joe has already reserved 16 rooms, therefore the number of additional rooms needed to be reserved = 50 - 16 = 34 rooms. At least 34 rooms have to be reserved, if B is the number of additional blocks that Joe reserves, the inequality is:
B ≥ 34
2) Each block contains 8 rooms therefore the minimum number of block (a) needed to be reserved = 34/8 = 4.25 = 5 to the next whole number. Therefore the minimum number of blocks needed is given as:
a ≥ 5
Since each block cost $900, let c represent the minimum amount of money needed, therefore the least amount of money needed is given as:
c = $900(5) = $4500
c ≥ $4500
Here, we are required to determine which inequality describes the scenario in the question and the least amount of money that Joe can spend to get the amount of rooms they need.
(1) The inequality which best describes the scenario is; B ≥ 4.25.
(2) The least amount of money that Joe can spend to get the amount of rooms they need is; $4500
First, since they need at least 50 total rooms and Joe had already reserved 16 rooms.Therefore, Joe needs to reserve an additional 34 rooms to completely accomodate people who are going on the trip.And since, he can only reserve rooms in blocks with each block containing 8 rooms;The number of blocks he needs to reserve; B ≥ 4.25.
Therefore, since only whole blocks can be reserved, Joe needs to reserve 5 blocks.Therefore, since one block costs $900, then, 5 blocks will cost $900 × 5 = $4500.Read more:

Answer:
when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°.
Step-by-step Explanation:
The relationship between an intercepted arc and an inscribed angle is given as:
the measure of the intercepted arc = twice the inscribed angle that intercepts it.
Also, by virtue of this, when two inscribed angles intercepts the same arc, both inscribed angles are said to be congruent. And the measure of both angles equal the measure of the arc they both intercept.
Therefore, if the measure of an arc, that is intercepted by 2 inscribed angles, is given as 75°, both inscribed angles equal 75° as well. Thus, each of the inscribed angles is half the measure of the intercepted arc.
Therefore, the statement that is true about inscribed angles is: "when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°."

Gas costs 1.35 per gallon and Jose had 81 dollars for gasoline
with this info we can find out how many gallons of gas Jose can buy.
81 divided by 1.35 is 60 gallons of gas
we also know that he can travel 34 miles for each gallon of gas
with this we can find out how far jose can travel
34 multiplied by 60 is 2040 miles
so, with $81, Jose can travel 2040 miles if gas prices are $1.35

Use the rule "subtract 6" to create a sequence of 10 numbers starting with 100. (explanation/work needed)
Answers
Answer:
100 -6 = 94
94 - 6 = 88
88 - 6 = 82
82 - 6 = 76
76 - 6 = 70 We can then show and prove 70 -> 64.
64 -> 58
58 -> 52
52 -> 46
46 -> 40
As numbers that end in 0, decrease to units that end in 4,8,2,6,and back to zero.
= all numbers that end with 0 have numbers that end in 4,8,2,6,0 when subtracting 6.
As 6 x 10 = 60 and 60 +40 = 100
We cna prove 4+8+2+6 = 20
20+20 = 40 and would continue this pattern to get to 10 we can then see the sequence of how 30/6 and proves each 5 number coordinate being 4,8,2,6,0 until we get to 10.
We then find 4,-2,-8,-14,and-20 it skips out 2 and 6 here on the neutral line but then starts and changes the sequence end numbers to -26 -32, -38,-44 and -50. This proves that-2 and -8 has significance and shows us a real sum that on negative -2 -8 = 6
The inverse of the 40 marker in the positive shows us 60
and 60 -50 = 10 being our 2nd positive closest to zero.
These were repeated twice and show 40 deducted and a further 18 as 0 counts for 2 subtractions 100-6 70-6 just like 94 +6 = 100 and like 70+6 = 76 and 40+6 = 46
3 x 6 = 18
40+ 18 = 58
100-58 = 42 and shows us a reflection again with 4 and 2
not just 4+2 = 6 it shows is 4/2 = 2 42/2 = 21 and 7 being a divider represents the first sequence group of 10 from 100 being 70 and just as significant in a decrease of 6 in relation to 100.
100-70 = 30
30-6 = 24
24 / 6 = 4
and we mark 4 as our first unit with relation to 100 and its decrease of 6 in sequence.
This may help you remember that 30 x 100 = 3000 and would be increasing by 6 x 180 times. But when we decrease from here we find 2400 a likely number as 3000-600 - 2400
This may help you remember that 400/6 = 66.6666666667 and why decrease always ends up as negative when 400 x 6 = 2400 and is a much more dividable number. and that 400 is not dividable by 6 in the first place, and may be linked to why a neutral zero number may show 4 and 10 and -2 and -8 where all these numbers divide into 400 6 just doesn't work in any even hundred number below 1200 except for 600 as we know and recall 6 divides into 30 and 18 but not into 40, just counts back to inverse 40 from 100 as its counting 2 x 30 = 60. It does divide into 2400 and that is a midway point back down to 1800 from 3000. So this may help you remember divisors of larger numbers.
Lines CD and DE are tangent to circle A shown below: If Arc CE is 112°, what is the measure of ∠CDE? a 124° b 136° c 68° d 56°
Answers
Answer:
C
Step-by-step explanation:
The central angle of this is 112 degrees. That is CAE is 112 degrees. That being the case, CDE is 90 + 90 + 112 = 292 Tangents make a 90 degree angle with the center of the circle.
CDE = 360 - 292 = 68
C
The measure of ∠CDE is 68degrees
This question bothers on circle geometry;
From the diagram, we can see that ACDE will form a quadrilateral. Since the sum of angles of a quadrilateral is 360degrees, hence;
[tex]<CDE + arcCE+<C+<E=360[/tex]
From the diagram, since CD and DE are both tangential to the circle at point C and E, this shows that <E = <E = 90°
substituting the given values in the formula;
[tex]<CDE+112+90+90=360\\<CDE + 292=360\\<CDE=360-292\\<CDE =68^0[/tex]
Hence the measure of ∠CDE is 68 degrees

Answer:
The value representing one standard deviation to the right of the mean is 55.
Step-by-step explanation:
The provided data set is:
S = {56, 54, 45, 52, and 48}
Compute the mean and standard deviation as follows:
[tex]\mu=\frac{1}{n}\sum X=\frac{1}{5}\times [56+54+45+52+48]=51\\\\\sigma=\sqrt{\frac{1}{n}\sum (X-\mu)^{2}}=\sqrt{\frac{1}{5}\cdot {(56-51)^{2}+...+(48-51)^{2}}}=\sqrt{\frac{1}{5}\times 80}=4[/tex]
Compute the value representing one standard deviation to the right of the mean as follows:
[tex]X=\mu+1\cdot \sigma[/tex]
[tex]=51+(1\times 4)\\=51+4\\=55[/tex]
Thus, the value representing one standard deviation to the right of the mean is 55.
