What is is the equation of the line perpendicular to y = 3x-7 that contains the point (6,8)?
A. 1/3x - 7
B. 1/3x + 6
C. -1/3x - 7
D. -1/3x + 10
Answers
m = -1/(3) = -1/3
Only choices C and D have this slope. Only choice D goes through the given point. (-1/3)*6 +10 = -2 +10 = 8.
The appropriate selection is ...
D. (-1/3)x + 10
The equation of the line perpendicular to y = 3x -7 that passes through the point (6, 8) is Option D. y = -1/3x + 10. The slope of the perpendicular line is -1/3. Using point-slope form, we determine the final equation.
To find the equation of a line perpendicular to y = 3x - 7 that passes through the point (6, 8), we must determine the slope of the perpendicular line first.
The slope of the given line is 3. The slope of a line perpendicular to this one is the negative reciprocal of 3, which is -1/3.
We now use the point-slope form of the linear equation, which is:
y - y₁ = m(x - x₁)
Substitute m = -1/3 and the point (6, 8):
y - 8 = -1/3(x - 6)
Distribute -1/3:
y - 8 = -1/3x + 2
Add 8 to both sides:
y = -1/3x + 10
Thus, the equation is Option D. -1/3x + 10.

a²= 24336/145
x²/a²-y²/b²=1
145x²/24336 + 145y²/169=1
The equation of the conic section is [tex]\frac{145x\²}{24336} - \frac{145y\²}{169}=1[/tex]
The foci of the hyperbola are given as: (13,0) and (-13,0)
The asymptote is given as [tex]y =\pm 12x[/tex]
Divide both sides of [tex]y =\pm 12x[/tex] by x.

Make b^2 the subject
[tex]b^2 = \frac{169}{145}[/tex]
Recall that [tex]a = \pm 12b[/tex]
Square both sides
[tex]a^2 = 144b^2[/tex]
Substitute [tex]b^2 = \frac{169}{145}[/tex]
[tex]a^2 = 144 \times \frac{169}{145}[/tex]
[tex]a^2 = \frac{24336}{145}[/tex]
The equation of the conic section is represented as:

Substitute known values
[tex]\frac{x^2}{24336/145} - \frac{y^2}{169/145} = 1[/tex]
Rewrite as:
[tex]\frac{145x\²}{24336} - \frac{145y\²}{169}=1[/tex]

Suppose you have an isosceles triangle, and each of the equal sides has a length of 1 foot. suppose the angle formed by those two sides is 45^\circ. then the area of the triangle is
Answers
The base angles are congruent and measure 67.5 deg.
The congruent sides measure 1 ft.
Use law of sines to find the length of the base.
[tex] \dfrac{\sin 67.5^\circ}{1~ft} = \dfrac{\sin 45^\circ}{b} [/tex]
[tex] b = \dfrac{\sin 45^\circ}{\sin 67.5^\circ}~ft [/tex]
[tex] b = 0.765~ft [/tex]
Draw a height from the vertex of the 45-deg angle to the base.
Half of the base is 0.765 ft/2 = 0.383 ft
We can find the height of the triangle using the small triangles.
0.383^2 + h^2 = 1^2
h = 0.9239 ft
A = bh/2 = 0.765 * 0.9239/2 ft^2
A = 0.354 ft^2
The area of a given isosceles triangle with sides of 1 foot in length and a 45-degree angle between these sides is 0.5 square feet.
Explanation:The area of an isosceles triangle can be calculated using the formula 1/2 base times height. But since we know that the triangle is isosceles and the angle between the equal sides is 45 degrees, this forms a 45-45-90 degree triangle which is a special kind of triangle. In a 45-45-90 degree triangle, the lengths of the sides are in the ratio 1:1:√2. Therefore, the length of the base (which also serves as the height in this case) will be the same length as the equal sides, 1 foot. Substituting these into the formula for area, we get Area = 1/2 * 1 ft * 1 ft = 0.5 square feet.

A polynomial will be equal 0 if x=2, or x=11.
Answer:
[tex]x=2\text{ (or) }x=11[/tex]
Step-by-step explanation:
We have been given factors of a polynomial as [tex](x-2)[/tex] and [tex](x-11)[/tex]. We are asked to find the values of x that would make the polynomial equal to zero.
We will use zero product property of polynomials to solve our given problem. The zero product property of polynomials states that if any of two factors of a polynomial is zero, then their product will be equal to zero.
Upon equating our given factors to zero, we will get:
[tex](x-2)(x-11)=0[/tex]
[tex](x-2)=0\text{ (or) }(x-11)=0[/tex]
[tex]x-2=0\text{ (or) }x-11=0[/tex]
[tex]x-2+2=0+2\text{ (or) }x-11+11=0+11[/tex]
[tex]x=2\text{ (or) }x=11[/tex]
Therefore, [tex]x=2\text{ (or) }x=11[/tex] will make the polynomial equal to zero.

james just bought a large container of ice cream the label says that there are 16 servings of ice cream write a formula to help james determine the number of grams on one serving of ice cream x=number of grams of ice cream in the container y=number of grams per serving
Answers
Final answer:
To determine the number of grams per serving of ice cream, use the formula y = x / 16, where x is the total number of grams in the container and y is the number of grams per serving.
Explanation:
To determine the number of grams per serving of ice cream, we can set up a formula using the variables x and y. Since the container has 16 servings of ice cream, the total number of grams in the container can be represented as 16y (16 servings multiplied by the number of grams per serving).
So, the formula to determine the number of grams per serving (y) is: y = x / 16
For example, if the total number of grams in the container (x) is 800g, then the number of grams per serving (y) would be 800g / 16 = 50g.
Solve equation -6/7m=-84

-588m = -6
Divide bot sides of the equation by -588.
m = [tex] \frac{1}{98} [/tex], m ≠ 0
Lastly,, check if the solution is in the defined range (it is) to find your final answer.
[tex]m = \frac{1}{98} [/tex]
Let me know if you have any further questions.
:)
To solve the equation -6/7m = -84, multiply both sides by the reciprocal of -6/7, which is -7/6. The solution is m = 98.
To solve the equation -6/7m = -84, we need to isolate the variable m on one side of the equation. We can do this by performing the inverse operation of what is currently being done to m. Since m is being divided by -6/7, we can multiply both sides of the equation by the reciprocal of -6/7, which is -7/6, to cancel out the division on the left side.
The steps to solve the equation are:
Multiply both sides of the equation by -7/6:
-7/6 * (-6/7m) = -7/6 * -84
The left side simplifies to m, and the right side becomes m = 98.
So, the solution to the equation is m = 98.

A die is continuously rolled until the total sum of all rolls exceeds 375. what is the probability that at least 90 rolls are necessary?
Answers
Final answer:
To find the probability of at least 90 rolls being necessary for the total sum of all rolls to exceed 375, we need to consider the probabilities associated with each roll.
Explanation:
To find the probability of at least 90 rolls being necessary for the total sum of all rolls to exceed 375, we need to consider the probabilities associated with each roll.
The maximum possible sum from a single roll of a six-sided die is 6, so after 90 rolls, the maximum possible sum is 90 * 6 = 540. If the total sum exceeds 375, it means that at least one roll resulted in a value greater than 2.
To calculate the probability, we need to find the complement of the event that the total sum is less than or equal to 375, which is the event of the total sum being greater than 375. Let's assume that the probability of rolling a value greater than 2 is p. The probability of at least 90 rolls being necessary is 1 - (1 - p)^90.

Find an equation in standard form for the ellipse with the vertical major axis of length 16 and minor axis of length 4
Answers
Given the lengths of the major and minor axes of an ellipse, one can derive the standard form equation of the ellipse. In this example, the lengths were 16 and 4, yielding a standard form equation of x²/4 + y²/64 = 1.
Explanation:The subject of this question is about finding the standard form equation for an ellipse given the lengths of the major and minor axes. To find the equation of the ellipse, we need to identify the semi-major axis (a) which is half the length of the major axis, and the semi-minor axis (b), which is half the length of the minor axis.
In this case, the lengths of the major and minor axes are 16 and 4 respectively, which gives us a semi-major axis of 8 and a semi-minor axis of 2. The standard form equation of an ellipse with a vertical major axis is given by:
(x-h)²/b² + (y-k)²/a² = 1
Where (h, k) is the center of the ellipse. In this case, since the center of the ellipse is at the origin (0,0), the equation becomes:
x²/4 + y²/64 = 1
