What is the domain function of -3(x-5)+8
↝ Quadratic Function has the domain of all real numbers. (Even not given the specific domain.)
↝ The equation [tex]y=-3(x-5)+8[/tex] is a parabola with (5,8) as a vertex. We call the equation [tex]y=a(x-h)^2+k[/tex] as vertex equation.
The domain of -3(x-5)+8 is all set of real numbers.
↝ Interval Notation ↝
Since the domain of the equation is set of all real numbers.
Therefore, the domain is x ∈ R or (-∞,∞) or -∞<x<∞
There of them work. Recall that the domain of quadratic function is all set of real numbers.

What is 10log3 in precalculus
WHEN WE ARE GIVEN the base 2, for example, and exponent 3, then we can evaluate 23.
23 = 8.
Inversely, if we are given the base 2 and its power 8 --
2? = 8
-- then what is the exponent that will produce 8?
That exponent is called a logarithm. We call the exponent 3 the logarithm of 8 with base 2. We write
3 = log28.
We write the base 2 as a subscript.
3 is the exponent to which 2 must be raised to produce 8.
A logarithm is an exponent.
Since
104 = 10,000
then
log1010,000 = 4.
"The logarithm of 10,000 with base 10 is 4."
4 is the exponent to which 10 must be raised to produce 10,000.
"104 = 10,000" is called the exponential form.
"log1010,000 = 4" is called the logarithmic form.
Here is the definition:
logbx = n means bn = x.
That base with that exponent produces x.
Example 1. Write in exponential form: log232 = 5.
Answer. 25 = 32.
Example 2. Write in logarithmic form: 4−2 = 1

Example 3. Evaluate log81.
Answer. 8 to what exponent produces 1? 80 = 1.
log81 = 0.
We can observe that, in any base, the logarithm of 1 is 0.
logb1 = 0
Example 4. Evaluate log55.
Answer. 5 with what exponent will produce 5? 51 = 5. Therefore,
log55 = 1.
In any base, the logarithm of the base itself is 1.
logbb = 1
Example 5 . log22m = ?
Answer. 2 raised to what exponent will produce 2m ? m, obviously.
log22m = m.
The following is an important formal rule, valid for any base b:
logbbx = x
This rule embodies the very meaning of a logarithm. x -- on the right -- is the exponent to which the base b must be raised to produce bx.
The rule also shows that the exponential function bx is the inverse of the function logbx. We will see this in the following Topic.
Example 6 . Evaluate log3 1
9 .
Answer. 1
9 is equal to 3 with what exponent? 1
9 = 3−2
log3 1
9 = log33−2 = −2.
Compare the previous rule.
Example 7. log2 .25 = ?
Answer. .25 = ¼ = 2minus2. Therefore,
log2 .25 = log22−2 = −2.
Example 8. log3Logarithms = ?
Answer. Logarithms = 31/5. (Definition of a rational exponent.) Therefore,

An astronaut who weighs 126 pounds on Earth weighs only 21 pounds on
the moon. How much would a person who weighs 31 pounds on the moon
weigh on Earth? Show your work to receive full credit.
Answer:
186 pounds
Step-by-step explanation:
let x = pounds on Earth
set up a proportion: [tex]\frac{126}{21}[/tex] = [tex]\frac{x}{31}[/tex]
cross-multiply: 21x = 3906
divide by 21: x = 186
Answer:
186 pounds.
Step-by-step explanation:
By proportion 126/21 = x/31
6 = x/31
x = 6*31
= 186 pounds.

What is a Triangle?A triangle is defined as simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes, it is represented by the symbol of Δ and consists of three connected vertices. Triangles can be categorized into a number of different varieties according on their sides and angles.
A triangle has three sides, three vertices, and three interior angles.
The angle sum property of a triangle states that the sum of the three interior angles of a triangle is always 180°
In ΔDEF,
Side DE is opposite of angle ∠ F
Side DF is opposite of angle ∠ E
Side EF is opposite of angle ∠ D
The sides in order from longest to shortest : Side DE > Side EF = Side DF
The longest side is always opposite of the largest angle, and the smallest side is always opposite of the smallest angle.
Hence, the angle in order from longest to shortest : angle ∠ F > angle ∠ D > angle ∠ E
Thus, the largest measure of angle is angle ∠ F.

Jeremy wants to give a 20% gratuity to his cab driver. His fare is $35.50. What is the total amount he will pay the driver? $7.10 $17.75 $42.60 $63.90 (32 dollars) (185 percent) = 59 dollars and 20 cents
Answer:
$42.60
Step-by-step explanation:
His fare = $35.50
Gratuity = 20% of the fare
= 20/100 × $35.50
= 0.2 × $35.50
= $7.10
Total amount he will pay the driver = His fare + amount of gratuity
= $35.50 + $7.10
= $42.60
He will pay the driver a total of $42.60

Here are the first five terms of an arithmetic sequence.
7
13
19
25
31
Prove that the difference between the squares of any two terms of the sequence is always
a multiple of 24.
9514 1404 393
Answer:
the difference of squares is 24(3n+2), so a multiple of 24
Step-by-step explanation:
The sequence has a first term of 7 and a common difference of 6, so the n-th term is ...
a[n] = a1 +d(n -1)
a[n] = 7 + 6(n -1)
a[n] = 6n +1
Then the (n+1)-th term is ...
a[n+1] = 6(n+1) +1 = 6n +7
The difference of the squares of these terms is ...
a[n+1]^2 -a[n]^2 = (6n+7)^2 -(6n+1)^2
= (36n^2 +84n +49) -(36n^2 +12n +1)
= 72n +48
= 24(3n +2) . . . . . always a multiple of 24
The difference of squares of terms n and n+1 is 24(3n+2), a multiple of 24.
_____
Check
The difference between squares for n=1 and n=2 is 13^2 -7^2 = 169 -49 = 120. The formula tells us the difference is 24(3·1 +2) = 24·5 = 120, in agreement.
