The answer is given below
Step-by-step explanation:
The equation of a quadratic function is given by:
Ax² + Bx + C where A, B and C are the coefficients of the quadratic equation. If the coefficient of x² (i.e A) is a negative value then the graph opens down, the value of C determines the y intercept.
The equation of a parabola with y-intercept greater than 3 and opens down can be given as -2x² -6x + 4. Since the coefficient of x² is negative it opens down and C = 4, it has a y intercept of 4 > 3
Let us assume a vertical stretch of 2, the new equation becomes:
2(-2x² -6x + 4)
-4x² - 12x + 8
To solve:
-4x² - 12x + 8 = 0
A = -4, B = -12 and C = 8
Using the quadratic formula:
[tex]x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}\\ x=\frac{-(-12) \pm \sqrt{(-12)^2-4(-4)(8)} }{2(-4)}=\frac{12 \pm 16.49}{-8} \\x= -3.6 \ or \ x=0.6[/tex]

f(x) = x2. What is g(x)?
Answer:
g (x-2) = x
Step-by-step explanation:
Set up the composite result function g (f(x))
Then Evaluate g (f(x)) by substituting in the value of F into G: g (x-2) = (x-2) + 2
finally Combine the opposite terms in (x-2) + 2: add -2 and 2: g(x-2) = x+0: add x and 0: g(x-2) = x
Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit in the triangle is centered at (0,0) and passes through the point (1.2,1.6). Approximately what percentage of the triangle does the circle cover?
Answer:
52.36%
Step-by-step explanation:
I did this problem on a test
52.33% is the percentage of the triangle does the circle cover.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Area of triangle = 24 sq units
Center of Circle is at (0, 0) and the circle passes through (1.2, 1.6).
We need to find the percentage of triangle covered by circle.
we need to find the area of circle.
To find the area of circle, we need the radius of circle.
Radius of circle is the distance between the center of circle and any point that lies on the periphery of the circle.
Radius = =√(1.2-0)²+(1.6-0)²
=2 units
Now, area of circle is given by the formula:
Area = πr²=3.142×4=12.56 sq units
Percentage of Triangle covered:
Area of circle/Area of triangle × 100
12.56/24× 100
52.33%
Hence, 52.33% is the percentage of the triangle does the circle cover.

Which set represents the domain of the function shown? (5 points)
{(−3, 6), (0, 2), (4, 7), (11, 15)}
{(6, −3), (2, 0), (7, 4), (15, 11)}
{2, 6, 7, 15}
{−3, 0, 4, 11}
Answer:
To make it simple, when finding the domain all you have to do is look for the x within the points.
Looking at the first set you can tell that the domain is -3, 0, 4, and 11
The y or the f(x) would be 6, 2, 7, and 15
(Just saying y and f(x) are the same thing.)
For the next set the domain is 6, 2, 7, and 15
For the f(x) it is -3, 0, 4, and 11
Remeber x and Domain is the same thing so all you have to do is look for the x within the points of the plot, as for looking for the range, it is the same thing as y or f(x).

Step-by-step explanation:
A special type of password consists of 3 different letters of the alphabet, and the two different numbers, where each letter and each number is used only once. How many different possible passwords are there?
Answer:
There can be 14,040,000 different passwords
Step-by-step explanation:
Number of permutations to order 3 letters and 2 numbers (total 5)
(AAANN, AANNA,AANAN,...)
= 5! / (3! 2!)
= 120 / (6*2)
= 10
For each permutation, the three distinct (English) letters can be arranged in
26!/(26-3)! = 26!/23! = 26*25*24 = 15600 ways
For each permutation, the two distinct digits can be arranged in
10!/(10-2)! = 10!/8! = 10*9 = 90 ways.
So the total number of distinct passwords is the product of all three permutations,
N = 10 * 15600 * 90 = 14,040,000
Solve for zzz. 42=-7(z-3)42=−7(z−3)
Answer:
False
Step-by-step explanation:
Well to solve for z we single it out, distribute, use the communicative property, and combine like terms.
42 = -7(z - 3)42 = -7(z - 3)
Distribute
42 = -7z + 21*42 = -7z + 21
42 = -7z + 882 = -7z + 21
-42 to both sides
-7z + 840 = -7z + 21
-21 to both sides
-7z + 819 = -7z
+7z to both sides
819 = 0
Thus,
the given equation is false.

In parallelogram ABCD, m∠ABD = 83°, m∠BDA = 34°, and m∠BCD = °.
This question is incomplete
Find attached to this answer the appropriate diagram required to answer the question.
This diagram was obtained online.
Answer:
63°
Step-by-step explanation:
We are told in the above question that for parallelogram ABCD, ∠ABD=83° and ∠BDA=34°.
To get the above angles, parallelogram ABCD was split into two triangles by a diagonal given us ∆ABD and ∆BCD
Remember that angles in a triangle = 180°
∆ABD has ∠ABD=83°, ∠BDA=34° and ∠DAB
180° = ∠ABD + ∠BDA+ ∠DAB
180° = 83° + 34° + ∠DAB
∠DAB = 180°-117°
=63°
Since ∆ABD and ∆BCD are similar triangles because they are from one parallelogram,
∠DAB = ∠BCD
= 63°
Therefore, the measure of the angle BCD is 63°.
Answer:
The answer is 63

Which simplified fraction is equivalent of 5.6 3/15 14/25 5/6 14/250
Answer:
Thus, 28/5 is equivalent of 5.6
Step-by-step explanation:
Given
Number is 5.6
it is in decimal form.
The first number after decimal represent the tenth of number
The Second number after decimal represent the hundredth of number
and similarly we can define thousandth of a number.
Step to write decimal number in fractional form is (say a.bcd
write the full number without decimal
so number will be
abcd
divide the number by 1
abcd/1
now count the number of digit after decimal and put as many 0's after 1
there are three digits after decimal, we will put three digit after 1 in denominator
thus number in fraction is
abcd/1000
_________________________________________________
Given number is 5.6
hence writing it in fractional form as explained above
5.6 = 56/10
56 = 28*2
10 = 2*5
5.6 = 56/10 = 2*28/2*5 = 28/5
Thus, 28/5 is equivalent of 5.6

Which transformations can be used to carry ABCD onto itself? The point of
rotation is (3,2). Check all that apply.
Answer:
A and B
Step-by-step explanation:
For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.
For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.
For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.
For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.

The true statement concerning the exterior angles of a triangle is that it forms a linear pair with one of the interior angles of the triangle.
What is the exterior angle of a triangle?The exterior angle theorem asserts that the total of the opposing and non-adjacent internal angles of a triangle equals the measurement of each exterior angle.
When one side of a triangle is stretched in such a way that a non-straight angle is produced exterior of the triangle but near to an interior angle, an external angle is formed.
Therefore, we can conclude that the true statement concerning the exterior angles of a triangle is that it forms a linear pair with one of the interior angles of the triangle.

Match the function with its value.

h[f(5)] -g[h(1)] Choose...
Answer:
1.) x^2 + 3x
2.) 3x^2 - 3x
3.) 278
Step-by-step explanation:
You are given the following functions:
f(x) = x + 5
g(x) = x2 + 4x + 5
h(x) = 3x2 - 2x + 5
1.) To match the function with its value,
(f+g)(x) = f(x) + g(x)
Substitutes for the two functions
X + 5 = x^2 + 4x + 5
Collect the like terms and equate them to zero
X^2 + 4x - x + 5 - 5
X^2 + 3x
Therefore, (f+g) (x) = x^2 + 3x
2.) (f*h)(x) = f(x) × h(x)
x + 5 = 3x^2 - 2x + 5
Collect the like terms
3x^2 - 2x - x + 5 - 5
3x^2 - 3x
Therefore, (f×h)(x) = 3x^2 - 3x
3.) h[f(5)] -g[h(1)]
First find f(5)
That is, substitute x for 5 in f(x)
f(5) = 5 + 5 = 10
Also, do the same for h(1)
h(1) = 3(1)^2 - 2(1) + 5
h(1) = 3 - 2 + 5 = 6
h[f(5)] - g[h(1)]
= 3(10)^2 - 2(10) + 5 - (6)^2 + 4(6) + 5
= 300 - 20 + 5 - 36 + 24 + 5
= 334 - 56
= 278
Therefore, h[f(5)] - g[h(1)] = 278

A swim team must be chosen from 10 candidates. What is the greatest number of different four-person teams that can be chosen?
Answer:
210 combinations
Step-by-step explanation:
The total number of candidates given = n = 10
The number of candidates to be chosen = r = 4
As in this, the sequence of the chosen candidates doesn't matter, we can use Combination to find the solution.
C(n,r) = n! / (n-r)! (r)!
where n = 10 and r = 4
C(10,4) = 10! / (10-4)! (4)!
C(10,4) = 10! / 6! 4!
C(10,4) = (10·9·8·7·6·5·4·3·2·1) / (6·5·4·3·2·1)(4·3·2·1)
C(10,4) = (10·9·8·7) / ((4·3·2·1))
C(10,4) = 210 combinations
