Answer:
To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you'll use that value to solve for y (or x if your parabola opens to the side) by using the quadratic equation. Those two coordinates are your parabola's vertex.

Find the amplitude of f(x) = 8 sin(6x + 4) – 3.
9514 1404 393
Answer:
8
Step-by-step explanation:
The amplitude is the coefficient of the sine function: 8.
Answer:
8
Step-by-step explanation:
Amplitude is the onehalf of highest value minus the lowest value
since sine function has maximum 1 and minimum -1, then the highest value of f(x) is 8(1) - 3 = 5 and the minimum value is 8(-1)-3 = -11.
Therefore the amplitude is (1/2) ( 5 +11) = 8.

Liam's monthly bank statement showed the following deposits and withdrawals:
$32.35, -−$114.95, $63.09, $98.79, -−$79.41
If Liam's balance in the account was $62.45 at the beginning of the month, what was the account balance at the end of the month?
Answer:
I think it's $62.32?
Step-by-step explanation:
1. $62.45 USD subtracted by ($114.95 + $79.41) = -131.91 USD
2. $-131.91 + ($32.35 + $63.09 + $98.79) = $62.32

Answer:
x = 1 or
x = - 7
To get rid of the square root. Isolate the square root and it's multiple. Then square both sides to get rid of it. Don't forget to square the multiple, in this case - 2 becomes 4. Solve for x like you normally do.
How do you do this. Please give a full answer and explain why.
Law of Exponent
[tex] \displaystyle \large{ {a}^{ - n} = \frac{1}{ {a}^{n} } }[/tex]
Compare the terms.
[tex] \displaystyle \large{ {a}^{ - n} = {( - 2)}^{ - 3} }[/tex]
Therefore, a = -2 and n = 3. From the law of exponent above, we receive:
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ {( - 2)}^{ 3} } }[/tex]
Exponent Def. (For cubic)
[tex] \displaystyle \large{ {a}^{3} = a \times a \times a }[/tex]
Factor (-2)^3 out.
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{( - 2) \times ( - 2) \times ( - 2)}}[/tex]
(-2) • (-2) = 4 | Negative × Negative = Positive.
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{4 \times ( - 2)}}[/tex]
4 • (-2) = -8 | Negative Multiply Positive = Negative.
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ - 8}}[/tex]
If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.
Hence,
[tex] \displaystyle \large \boxed{ {( - 2)}^{ - 3} = - \frac{1}{ 8}}[/tex]
The answer is - 1 / 8

Answer:
Step-by-step explanation:
if you need an answer I would be 112 given the information in the question,
but there seems to be something wrong (probably my interpretation) ..
here is the logic (and why there is an issue) ....
Assuming that every "movement" is "5 forward, then 3 back"
we can assume that every movement takes 8 steps ...
given this one would assume that the total steps has to be a multiple of 8 (but it is not)
460/8 is 57.5 ....
let us assume that came out even... every movement has five forward and three back a net result of 2 forward... if the is repeated 57.5 time the result would be 112 steps forward
it is the 57.5 that does not seem correct
A dietitian prepares a high-protein drink for 24 residents. If each drink measures 3/4 cup, how many total cups of the drink will she prepare?
Number of cups are 32.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A dietitian prepares a high-protein drink for 24 residents.
And, Each drink measures 3/4 cup.
Let number of cups of the drink will she prepare = x
So, We get;
⇒ 3/4 × x = 24
⇒ x = 24 × 4 / 3
⇒ x = 32 cups
Thus, There are 32 total cups of the drink will she prepare.

Answer:
264x³-66x
Step-by-step explanation:
The order of operations requires this be evaluated as ...
11x(96x÷4x -6) . . . . given
11x(24x·x -6) . . . . . . division inside parentheses
11x(24x² -6) . . . . . . multiplication inside parentheses
264x³ -66x . . . . . multiply by outside factor (use the distributive property)
_____
Additional comment
The appearance of the expression in parentheses may induce you to evaluate it as (96x)÷(4x) = 24. The order of operations requires that you do the division before the multiplication, left to right, so this must be evaluated as ...
((96x)÷4)x = 24x²
You need to be very careful with division and with exponents to make sure to follow the Order of Operations exactly. If you have an appropriate calculator, it will do that automatically. For example, if you tell your calculator ...
(for x=2) 11×2×(96×2÷4×2-6)
it should give you the result 1980, not 396.
Answer:
= 198x
Step-by-step explanation:
11x × { 96x ÷ 4x -6}
11x × { 24x -6}
264x - 66x
= 198x

Find the y-intercept.
5 = 1(4) + b
5 = 4 + b
1 = b
So the equation of the line AB is y = x + 1.
The slope of a perpendicular line is the opposite reciprocal of the original line.
1 -> -1/1 -> -1

Your 5 neighboring restaurants charge $9.95, $12.95, $8.50, $8.95, and $10.50 for a hamburger special. What is the mean price?
Answer:
$10.17
Step-by-step explanation:
Mean simply is defined as "average", so the average price of a hamburger across five resturaunts is found by adding all of the prices together and then dividing by the number of prices there are.
9.95 + 12.95 + 8.50 + 8.95 + 10.50 = 50.85 dollars, which then you divide by 5, and end up with the solution: $10.17

Determine an expression that represents:
Perimeter =
Area =
Answer:
P = 50x + 11
A = ((12x +3 ) × (14x +13)) + ( 1/2 (6x-4)^2)
Step-by-step explanation:
P =( the triangle - the shared side) +( the rectangular P - the shared side with the triangle )
P =2(6x - 4) + (14x +13) + 2 (12x +3)
P = 12x -8 + 14 x + 13 +24x +6
P = 50x + 11
Area = Triangle area + Rectangular area
T area = 1/2 base × hight
1/2 (6x-4) (6×-4)
= 1/2 (6x-4)^2
Rectangular Area = hight × length
= (12x +3 ) × (14x +13)
A = ((12x +3 ) × (14x +13)) + ( 1/2 (6x-4)^2)
