Using translation concepts, it is found that:
a.
The equation is: y = -1.5(x + 4)² + 9.The domain is all real values.The range is y ≤ 9.b.
The rule is [tex]y = -\sqrt{x + 5} + 10[/tex].The domain is x ≥ -5.The range is y ≤ 10.What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
Quadratic functionThe quadratic function has vertex at (-4,-6), hence:
y = a(x + 4)² - 6
When x = -6, y = 0, hence we use it to find a as follows:
0 = 4a - 6
a = 1.5.
Hence the function is:
y = 1.5(x + 4)² - 6.
When it is reflected over the x-axis, we have that:
y -> -y.
Hence:
y = -1.5(x + 4)² + 6.
When it is moved up 3 units, we have that y -> y + 3, hence:
y = -1.5(x + 4)² + 9.
The function is defined for all real values, assuming values from negative infinity to 9, hence:
The equation is: y = -1.5(x + 4)² + 9.The domain is all real values.The range is y ≤ 9.Square root functionThe parent square root function is given by:
[tex]y = \sqrt{x}[/tex]
From the graph, it is found that:
The function was reflected over the x-axis, hence y -> -y.The function was shifted one unit to right, hence x -> x - 1.The function was shifted two units up, hence y -> y + 2.Hence the rule is:
[tex]y = -\sqrt{x - 1} + 2[/tex]
The translations given by the item are:
6 units left, hence x -> x + 6.8 units up, hence y -> y + 8.Thus:
[tex]y = -\sqrt{x + 5} + 10[/tex]
Then the function will be defined for values of -5 and greater, assuming values of 10 and less, hence:
The rule is [tex]y = -\sqrt{x + 5} + 10[/tex].The domain is x ≥ -5.The range is y ≤ 10.More can be learned about translation concepts at https://brainly.com/question/4521517

Diven that 4x^3+x^(5/2) all over √x can be written in the form 4x^a+x^b, write down the value of a and the value of b
Answers
The value of a and the value of b is 6 and 5.
We can solve this problem by few steps, If we change the representation of power by replacing all powers according to √x or [tex] {x}^{1/2} [/tex]. We know that, [tex] {x}^{m/n × n/b } = {x}^{m/b} [/tex]
So, using this we can write, [tex] {4x}^{1/2 \times 6} + {x}^{1/2 \times 10/2} = {4 \sqrt{x} }^{6} + { \sqrt{x} }^{5} [/tex]..............(1)
Now if we compare the value of ( 1 ) with
[tex] {4 \sqrt{x} }^{a} + { \sqrt{x} }^{b} [/tex], we can easily find out the value of a and b and it is, a = 6 and b = 5
Thus, the value of a and b is 6 and 5.

Please help me find the rule of this linear function:
x-intercept: (-3.667,0)
y-intercept: (0,5.5)
Answers
Step-by-step explanation:
what do you mean by "rule" ?
the line equation (in slope-intercept form ? or any other ?) ?
or only the slope of the line ?
I assume you need the slope-intercept line equation.
this looks like
y = ax + b
"a" is the slope of the line, "b" is the y-intercept (the y value when x = 0).
"b" we know already from the specified intercept points : 5.5
the slope of a line is simply the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
and the axis-intercept points are points on the line too. so, we can use them.
so, we see
x changes by +3.667
(= 3 2/3 = 3×3/3 + 2/3 = (3×3 + 2)/3 = 11/3)
from -3.667 to 0.
y changes by +5.5
(= 5 1/2 = 5×2/2 + 1/2 = (5×2 + 1)/2 = 11/2)
from 0 to 5.5
the slope is therefore
5.5 / 3.667 = 11/2 / 11/3 = 11/2 × 3/11 = 3×11 / 2×11 = 3/2
and so, the line equation is
y = 3/2 x + 5.5
or
y = 3/2 x + 11/2 = 1/2 × (3x + 11)

Step-by-step explanation:
well, the starting equation and the target format have been given.
let's do the multiplications and compare the target with the starting information.
from there we see what is different or missing.
x² + 14x + 13 = 0
and
(x - p)² = q
x² - 2px + p² = q
x² - 2px + (p² - q) = 0
now let's compare the different parts :
x² = x²
-2px = 14x
-2p = 14
p = -7
p² - q = 13
-7² - q = 13
49 - q = 13
36 - q = 0
q = 36
so, the square (x - p)² = (x + 7)² is completed when
x² + 14x + 49 = 0
but we have only "+ 13". so we need to add 36 to get 49. but we need to do it on both sides, to keep the equation true :
x² + 14x + 13 + 36 = 36
x² + 14x + 49 = 36
(x + 7)² = 36
just as we calculated already above.
and now this can be solved by pulling the square root on both sides (a quadratic equation has always 2 solutions)
x + 7 = ±6
x1 = 6 - 7 = -1
x2 = -6 - 7 = -13

The possibilities of selecting a main dish = 14
The possibilities of selecting a dessert = 9
The meal combinations are: a starter dish and a main dish; a main dish and dessert; a starter dish, main dish and dessert dish.
The possibility of selecting each meal combinations would be,
1) a starter dish and a main dish = 7 × 14

Answers
There are 3 whole number with different values of x.
What is a whole number?
All positive integers from 0 to infinity are included in the group of numbers known as whole numbers. The number line has these numbers. They are all genuine numbers as a result. Although not all real numbers are whole numbers, we may argue that all whole numbers are real numbers. As a result, the set of natural numbers plus zero may be used to define whole numbers. The category of whole numbers and the negative of natural numbers is known as integers. Thus, integers can be either positive or negative, including 0. Natural numbers, whole numbers, integers, and fractions all fall under the category of real numbers.
Whole numbers refer to all natural numbers, including '0,' in their entirety. Examples include: 0, 11,1,2,3,4 etc
As stated in the question,
Accordingly, "x" is a positive integer. In order for the value of [tex]\sqrt{\frac{48}{x} }[/tex]to be a whole number, we must determine how many alternative values there are for the variable "x".Then, in order to determine which values of "x" the given fraction is a square for, we must first locate them.
We are aware that the factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
Now, from the above factors of 48 only (3,12 & 48) of can give us a square number.
Therefore,
If x is 3 then [tex]\sqrt{\frac{48}{3} }[/tex]=[tex]\sqrt{16}[/tex]=4If x is 12 then[tex]\sqrt{\frac{48}{12} }[/tex]=[tex]\sqrt{4}[/tex]=2If x is 48 then[tex]\sqrt{\frac{48}{48} }[/tex]=[tex]\sqrt{1}[/tex]=1Hence, There are 3 whole number with different values of x.

A large grain silo is to be constructed in the shape of a circular cylinder with a hemisphere attached to the top. The diameter of the silo is to be 30 feet, but the height is yet to be determined. Find the height h of the silo that will result in a volume of 11,475(3.14) ft cubed
Answers
The height of the silo is 56 feet.
Here, we are given that a large grain silo is to be constructed in the shape of a circular cylinder.
The diameter of the silo = 30 feet
⇒ The radius of the cylinder = 15 feet
and also the radius of the hemisphere = 15 feet
The volume of a hemisphere = 2πr^3/3
Volume = 2 × π × 15 × 15 × 15 × 1/3
Volume of cube = 2250π
Thus, the volume of cylinder = volume of the silo - volume of the hemisphere
= 11,475(3.14) - 2250π
π = 3.14
⇒ 11,475(3.14) - 2250(3.14)
3.14 (11,475 - 2250)
= 3.14 (9225)
= 9225π
Now, the volume of cylinder = πr^2h
Thus, 9225π = π(15) (15) h
9225π/ 225π = h
h = 9225/225
h = 41
Thus, the height of the cylinder = 41
The height of the silo will be the height of hemisphere + height of the cylinder = 15 + 41 = 56 feet.
