solve for s. s+s+1/2s if s=8
When "s" is equal to 8, the expression "s + s + 1/2s" evaluates to 32.
To solve for "s" in the expression "s + s + 1/2s" when "s" is equal to 8, we can substitute the value of "s" into the expression and simplify.
Substituting "s = 8" into the expression:
8 + 8 + (1/2) * 8
Simplifying:
16 + 8 + 4
28 + 4
32
Therefore, when "s" is equal to 8, the expression "s + s + 1/2s" evaluates to 32.

(07.03 MC) Given r = 10i - 5j and s = -2i + 6j, what is r + s?
The sum of vectors r and s is given by r + s = 8i + j. the sum of vectors r and s, we simply add the corresponding components of the two vectors
To find the sum of vectors r and s, we simply add the corresponding components of the two vectors.
Given r = 10i - 5j and s = -2i + 6j, we can add the i-component and j-component separately.
The i-component of the sum (r + s) is obtained by adding the i-components of r and s:
i-component: 10i + (-2i) = 10i - 2i = 8i
The j-component of the sum (r + s) is obtained by adding the j-components of r and s:
j-component: (-5j) + 6j = -5j + 6j = j
Combining the i-component and j-component, we have:
r + s = 8i + j
Therefore, the sum of vectors r and s is given by r + s = 8i + j.

Step-by-step explanation:
100= 125 + x First you have to subtract 125 on both sides so 125-125 and 100-125 and you will get -25=x
Answer:
[tex]\boxed {x = -25}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]100 = 125 + x[/tex]
-Switch sides:
[tex]100 = 125 + x[/tex]
[tex]125 + x = 100[/tex]
-Subtract [tex]125[/tex] on both sides:
[tex]125 - 125 + x = 100 - 125[/tex]
[tex]\boxed {x = -25}[/tex]

h(t) = -4.9t^2 + 29.4t + 5.9
Rewrite the function in vertex form.
Answer:
h(t) = -4.9(t - 3)^2 + 50.
Step-by-step explanation:
h(t) = -4.9t^2 + 29.4t + 5.9
h(t) = -4.9(t^2 - 6t) + 5.9 Complete the square on t^2 - 6t:
h(t) = -4.9[ (t - 3)^2 - 9] + 5.9
h(t) = -4.9(t - 3)^2 + 44.1 + 5.9
h(t) = -4.9(t - 3)^2 + 50
The function in vertex form is: h(t) = -4.9(t - 3)² + 50
To rewrite the function in vertex form, we need to complete the square. The vertex form of a quadratic function is given by:
h(t) = a(t - h)² + k
where (h, k) represents the coordinates of the vertex.
We have,
h(t) = -4.9t² + 29.4t + 5.9
First, factor out the common factor -4.9 from the first two terms:
h(t) = -4.9(t² - 6t) + 5.9
So, h(t) = -4.9(t² - 6t + 9 - 9) + 5.9
h(t) = -4.9((t - 3)² - 9) + 5.9
Next, distribute -4.9:
h(t) = -4.9(t - 3)² + 44.1 + 5.9
h(t) = -4.9(t - 3)^2 + 50
Therefore, the function in vertex form is: h(t) = -4.9(t - 3)² + 50

If AB is a straight line, find x
Answer:
x=20
Step-by-step explanation:
Straight lines= 180
x+4x+3x+20=180
Combine like terms
8x+20=180
Subtract 20 on both sides
8x=160
Divide by 8 on both sides
x=20
If AB is a straight line then value of x is 20.
What is Straight Line?A line is an infinitely long object with no width, depth, or curvature.
From the given figure we can say that the angles should be added to one eighty degrees.
x+4x+3x+20=180
Now add the like terms
8x+20=180
Eight times x plus twenty equal to one hundred and eighty.
Subtract 20 from both sides
8x=160
Divide both sides by x
x=20
Hence, if AB is a straight line then value of x is 20.

You buy hats for $20, and sell them for $5 each. What does the graph of the profits look like?
A: A curve that goes up
B: A line that goes down
C: A curve that goes down
D: A line that goes up
E: None
Answer:
B: A line that goes down
Step-by-step explanation:
if you sell a product for lesser price than what it cost then it will be a loss not profit.
Since the hats were bought for $20 and sold for $5 then the graph will be a line that goes down.
Not a curve, because all are bought at the same price, $20, and sold for the consistent price of $5.

Question 1, 6+4=10 marks. 1. Compute the Frenet apparatus k, 7, T,N and B of the following curve V2 2 a(s) = (1 - COS 8, 3+ coss, sin s). 2 Show that this curve is a circle and find its center and radius. 2. Consider the level surface S definned by f(x, y, z) = 0, where f is smooth and its partial derivatives do not all vanish at any point of S. Show that the gradient vector V (1,4,2)=(:: S:) is perpenducu- lar to the tangent plane T,S at any point p in S.
1. The Frenet apparatus of the curve is computed, yielding the curvature k, the tangent vector T, the normal vector N, and the binormal vector B.
2. It is shown that the given curve is a circle with a center and radius determined.
1. To compute the Frenet apparatus, we start by calculating the derivatives of the given curve:
- First, we find the first derivative: a'(s) = (0, -3sin(8s), cos(s)).
- Next, we compute the second derivative: a''(s) = (0, -3cos(8s), -sin(s)).
- Then, we calculate the tangent vector: T = a'(s)/||a'(s)||.
- The curvature is given by k = ||a''(s)||/||a'(s)||^2.
- To determine the normal vector, we normalize the second derivative: N = a''(s)/||a''(s)||.
- Finally, we find the binormal vector by taking the cross product of T and N: B = T × N.
2. To show that the curve is a circle, we examine its components:
- The x-component of the curve, a_1(s), is given by (1 - cos(8s)).
- The y-component, a_2(s), is (3 + cos(s)).
- The z-component, a_3(s), is sin(s).
- By analyzing these components, we can see that a_1(s) and a_3(s) describe a circle in the x-z plane, while a_2(s) remains constant.
- Therefore, the curve lies on a circle in 3D space.
The center and radius of the circle can be determined by observing that a_1(s) and a_3(s) correspond to the x and z coordinates of points on the circle, respectively.
- The center of the circle is located at (1, 0, 0) since a_1(s) reaches its maximum value of 2 when s = 0.
- The radius of the circle is 1, as a_1(s) ranges from 0 to 2.
In summary, the Frenet apparatus of the given curve is computed, providing the curvature, tangent vector, normal vector, and binormal vector. It is then shown that the curve is a circle with a center at (1, 0, 0) and a radius of 1.

A gym's membership in 2012 was 9,300. The current membership is 2,800. Which expression can be used to find the percent of change? WHAT EXPRESSION NOT WHAT THE PERCENT IT.
The expression that can be used to find the percent of change between the gym's membership in 2012 and the current membership is ((Current Value - Initial Value) / Initial Value) [tex]\times[/tex] 100.
To find the percent of change between the gym's membership in 2012 and the current membership, we can use the following expression:
Percent of change = ((Current Value - Initial Value) / Initial Value) [tex]\times[/tex] 100
In this case, the initial value is 9,300 (membership in 2012), and the current value is 2,800 (current membership).
Substituting these values into the expression, we get:
Percent of change = ((2,800 - 9,300) / 9,300) [tex]\times[/tex]100
Simplifying the expression further, we have:
Percent of change = (-6,500 / 9,300) [tex]\times[/tex] 100
Therefore, the expression that can be used to find the percent of change between the gym's membership in 2012 and the current membership is ((Current Value - Initial Value) / Initial Value) [tex]\times[/tex]100.
