Using proportions, it is found that the cost per ounce is of $0.8.
What is the missing information?The missing information is the number of ounces in the balm, that is of 20.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The cost per ounce is given by the proportion of the cost by the number of ounces, hence:
Cost: $16.Number of ounces: 20.Then:
$16/20 = $0.8.
The cost per ounce is of $0.8.

line gh contains points G(-2,6) and H(5,-3) what is the slope of gh?
The slope of line gh is [tex]\frac{-9}{7}[/tex] .
Line Slope is a measure of the slope and direction of a line . The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of the line. The net change in the y coordinate is Δy and the net change in the x coordinate is Δx. The slope of a line can be calculated from two points on the line. Given the coordinates of two points, we can use the equation for the slope of the line which is given by [tex]m=\frac{y_2-y_!}{x_2-x_1}[/tex] .......(1) where [tex](x_1,y_1)[/tex] is the coordinate of first point and [tex](x_2,y_2)[/tex] is the coordinate of second pointWe have given two points G(-2,6) and H(5,-3) .
Putting [tex]x_1=-2,y_1=6[/tex] and [tex]x_2=-5 ,y_2=-3[/tex] in equation (1) , we get

Differential Equations Dilemma
Show directly that the given functions are linearly dependent on the real line. That is, find a nontrivial linear combination of the
following functions that vanishes identically.
f(x) = 4x, g(x) = 2x², h(x) = 8x-12x²
Enter the non-trivial linearcombination.
(16)4x + (__)2x²+ (__)(8x-12x²) = 0
The equation with nontrivial linear combination is (16)4x + ( -48 )2x²+ (-8 )(8x-12x²) = 0
We can solve this problem following some steps.
Let's assume the value is A for blank one and it is B for blank two.
Now we can rewrite the equation as,
(16)4x + (A) 2x²+ (B)(8x-12x²) = 0
Or, 64x + 2Ax² + 8Bx - 12Bx² = 0
After rearrangement, we can write this equation as,
x ( 64 + 8B) + x²( 2A - 12B) = 0
We can consider the whole equation as zero, only when the coefficient of both x and x² is zero, To complete a nontrivial combination, we have to write,
∴ ( 64 + 8B) = 0 [ Coefficient of x ]
Or , 8B = -64
Or, B = -64/8 = -8
Again following the previous concept we can also write, ( 2A - 12B ) = 0
[ Coefficient of x² ]
Now, we should put the value of B = -8
∵ ( 2A - 12B ) = 0
Or, 2A + 96 = 0
Or, 2A = - 96
Or, A = - 48
So, the value of A is -48, and the value of B is -8
Now we can conclude,
(16)4x + ( -48 )2x²+ ( -8 )(8x-12x²) = 0

Find the reference angle for -7pi/5
Answer:
When the terminal side is in the first quadrant (angles from 0° to 90°), our reference angle is the same as our given angle. This makes sense, since all the angles in the first quadrant are less than 90°. So, if our given angle is 33°, then its reference angle is also 33°.
When the terminal side is in the second quadrant (angles from 90° to 180°), our reference angle is 180° minus our given angle. So, if our given angle is 110°, then its reference angle is 180° – 110° = 70°.
When the terminal side is in the third quadrant (angles from 180° to 270°), our reference angle is our given angle minus 180°. So, if our given angle is 214°, then its reference angle is 214° – 180° = 34°.
When the terminal side is in the fourth quadrant (angles from 270° to 360°), our reference angle is 360° minus our given angle. So, if our given angle is 332°, then its reference angle is 360° – 332° = 28°.

Given that A, O & B lie on a straight line segment, evaluate the size of the smallest angle.
The smallest angle on the line will be 36°
What do you understand by straight line segment?A line segment seems to be a straight line that connects two places. A line segment does indeed have a predetermined length. A ruler can be used to determine the shortest distance between the two points.
What is another name for a straight angle?A straight angle in geometry is an angle with a vertex point of 180 degrees. It basically generates a straight line with sides that point in opposite directions first from the vertex. It is also known as "flat angles."
According to the given data:We know the the sum of the straight angle is = 180°
So,
(5a + 18) + (48 - a) + (8a -30 ) = 180°
5a - a + 8a + 18 +48 - 30 = 180°
12a + 36 = 180°
12a = 180 - 36
a = 12°
So putting the value of a in the equation:
(5a + 18) = 5 *12 + 18 = 78°
(48 - a) = 48 - 12 = 36°
(8a -30 ) = 96 - 30 = 66°
36° < 66° <78°
So the smallest angle on the line will be 36°

Find the z-intercepts and the coordinates of the vertex for the parabola y=x2+6x+5 if there is more than one x intercept awpweate them with commas
The x-intercepts of the parabola are (-1,0) and (-5,0) and the coordinates of the vertex are ( -3 , - 4 ).
A parabola is a graphical representation of a function of the form y=g(x) where g(x) is a quadratic polynomial of x.
The locus of a point which is equidistant point also known as focus and equidistant from a given line known as directrix forms a parabola.The general equation of a parabola is given by y =4a(x-h)²+k(h, k) is the vertex of the parabola.The given equation of the parabola is y = x² + 6x + 5
to find the x-intercepts we have to take the value of y at zero.
∴ x² + 6x + 5 = 0
or, x² + 5x + x + 5 = 0
or, x (x + 5) + 1 ( x + 5 ) = 0
or, (x+5)(x+1)=0
either x=-5 or x=-1
Therefore the x-intercepts of the graph is (-1,0) and (-5,0)
Now to find the vertex of the parabola:
y = x² + 6x + 5
or, y = x² + 2·x·3 + 3² - 4
or, y = (x + 3)² - 4
Therefore from the above equation we can say that the vertex of the parabola is at ( -3 , - 4 ).

2x + 4y + 32 = 8
Answer:
It will be (x=1.y=6.z=-6
Answer:
Choice b
(x = 1, y = 6, z = -6)
Step-by-step explanation:
The system of equations is
3x + 4y + 3z = 9 (1)
3x + 3y + 3z = 3 (2)
2x + 4y + 3z = 8 (3)
Subtract (2) from (1) to eliminate the 3x and 3y terms and solve for y
(1) - (2)
==> 3x + 4y + 3z - (3x + 3y +3z) = 9 - 3
==> 3x + 4y + 3z - 3x - 3y - 3z = 6
(3x-3x) + (4y-3y) + (3z-3z) = 6
4y - 3y = 6
y = 6
Subtract (3) from (1) to isolate the x term
(3x - 2x) + (4y-4y) + (3z-3z) = 9 -8
x = 1
Divide equation (2) on both sides by 32 to eliminate the coefficients
Equation (2) ÷ 3
==> (3x + 3y + 3z) / 2 = 3/3
==> x + y + z = 1 (4)
Substitute the values of x and y in Equation (4)
1 + 6 + z = 1
7 + z = 1
Subtract 7 from both sides
==> z = 1-7 = 6
Answer:
(x = 1, y = 6, z = -6)

The function f(x) = (x+4)³ + 3
Let us assume,
y = (x+4)³ + 3
What is Invertible function?A function is said to be invertible when it has an inverse. It is represented by [tex]f^{-1}[/tex]. Condition for a function to have a well-defined inverse is that it be one-to-one and Onto or simply bijective.
Then,
y = (x+4)³ and y = 3
Therefore the inverse of y = 3 is the line x = 3
We can solve,
y = (x+4)³
The solution of Inverse function,
So,
[tex]\sqrt[3]{y} = x+4[/tex]
We can get,
[tex]x = \sqrt[3]{y} -4[/tex]
So the inverse of y is [tex]\sqrt[3]{x} -4[/tex]
f(x) = (x+4)³
So the inverse of f(x) is [tex]\sqrt[3]{x} -4[/tex]
Therefore, [tex]f^{-1}( x)[/tex] = [tex]\sqrt[3]{x} -4[/tex]
Then f(x) = 2
[tex]f^{-1} (x) = \sqrt[3]{x} - 4[/tex]
We can substitute f(x) = 2
[tex]f^{-1} (2) = \sqrt[3]{2} -4[/tex]
Since, ∛2 = 1.2599
We can substitute this value,
[tex]f^{-1} (2) = 1.2599-4[/tex]
[tex]f^{-1} (2) = -2.7401[/tex]
Therefore,
The value of ,

Harold estimates the total bill to be about $20,500. Apart from that Harold also had to pay 12% of $450 fee for prescription medications and a $250 late fee if she pays the bill after September 30. How much will Harold's total payment be if he pays on October 2nd?
Harold's total payment is $5,841.50.
What is Harold's total payment?Percentage is the fraction of a quantity that is expressed as a number out of hundred. The sign used to represent percentages is %. Percentages are a measure of frequency.
The total bill Harold would pay is the sum of the first $550, 25% of the remaining bill, 12% of the fee for prescription medications and the late payment fee since she paid after September 30.
Amount of total bill that Harold would pay = (100 - 75)% x (20,500 - 550)
25% x 19,950 = $4,987.50
Amount of the prescription medications Harold pays : 12% x 450 = $54

is the maximum distance?
A) 13.5 miles
B 16.0 miles
C11.5 miles
(D) 14.0 miles
The maximum distance Jameel can travel is 11.5 miles
How to determine the maximum distance?The equation that determines the distance is given as
2 + 0.4(4m - 1) = 20
Subtract 2 from both sides of the equation
So, we have
0.4(4m - 1) = 20 -2
Evaluate the like terms
So, we have
0.4(4m - 1) = 18
Divide both sides by 0.4
So, we have
(4m - 1) = 18/0.4
Evaluate the quotients
So, we have
(4m - 1) = 45
Remove the bracket
So, we have
4m - 1 = 45
Add 1 to both sides of the equation
4m = 46
Divide both sides of the equation by 4
So, we have
x = 11.5
Hence, the maximum distance Jameel can travel is 11.5miles
