At a sale, soccer cleats were sold for
$59.50. If the original price was :
$70, what
percentage of its original price were soccer
cleats sold for?

The percent of change is an increase in altitude of the weather balloon.

Change in altitude = New altitude - Original altitude

= 103 ft - 100 ft

= 3 ft

Percentage change = Change in altitude / Original altitude × 100

= 3 / 100 × 100

= 3%

Therefore, the percentage change in the altitude of the weather balloon is 3%.

The length of the vector u*v has a maximum value of 16 and a minimum value of 0, and it is moving in a positive z-direction.

Generally, the equation for is  mathematically given as

Consider the following vector:

[tex]\begin{aligned}\mathbf{v} &=0 \mathbf{i}+4 \mathbf{j}+0 \mathbf{k} \\&=\langle 0,4,0\}\end{aligned}[/tex]

Let us assume that u is a vector that has a length of four, that begins at the origin, and rotates in the x-y plane.

This vector creates a circle with the origin serving as the circle's center and a radius of 4.

So, the coordinates of u can be taken as,

[tex]u=(x\pm \sqrt{4^2-x^2 ,0})[/tex]

Here, 0 [tex]\leq[/tex]x [tex]\leq[/tex] 4.

Now, the cross product of the two vectors u and v is,

[tex]\begin{array}{ccc}\mathbf{i} & \mathbf{j} & \mathbf{k} \\x & \pm \sqrt{4-x^2} & 0 \\0 & 4 & 0\end{array}[/tex]

[tex]&=\mathbf{i}(0-0)-\mathbf{j}(0-0)+\mathbf{k}(4 x-0) \\&=4 x \mathbf{k}\end{aligned}[/tex]

The length of the vector u* v is,

[tex]\begin{aligned}|\mathbf{u} \times \mathbf{v}| &=\sqrt{(4 x)^2} \\&=4 x\end{aligned}[/tex]

Here, 0 <=x <= 4.

If x=4, then u*v is,

[tex]\begin{aligned}\mathbf{u} \times \mathbf{v}| &=4 \times 4 \\&=16 \\|\mathbf{u} \times \mathbf{v}| &=4 \times 0 \\&=0\end{aligned}[/tex]

In conclusion, As a result, the length of the vector u*v has a maximum value of 16 and a minimum value of 0, and it is moving in a positive z-direction.

The solution is Option D.

The length of the Zambezi river written in scientific notation is

L = 8.38 x 10⁷ feet

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

The length of the Zambezi river in feet L = 83,800,000 feet

Now , the scientific notation is given by in powers of 10

So ,

The value of L in scientific notation is given by

The value of L = 838 x 10⁵ feet

The value of L = 8.38 x 10² x 10⁵ feet

So , on simplifying the equation , we get

The value of L = 8.38 x 10⁷ feet

Therefore , the value of L is 8.38 x 10⁷ feet

Hence , The length of the Zambezi river written in scientific notation is

L = 8.38 x 10⁷ feet

By using properties of right triangles, we will see that the value of x is 7.72

In the image we have a set of right triangles, and we want to find the value of x.

Let's look at the large triangle in the left, we know that the hypotenuse measures 18 units and one angle measures 64°, with that information we can get the adjacent side (the dashed line, let's call it A) to that angle:

Cos(64°) = A/18

18*cos(64°) = A = 7.05

Now we know one of the cathetus of the smaller right triangle (the one we can see in the right side). Here we know one angle that measures 20° and the opposite to that angle measures 7.05

Then the value of x is given by the equation:

x = 7.05/sin(20°) = 7.72

We conclude that the value of x is 7.72

The probability that a randomly chosen participant in the survey will have visited both England and France is 0.5

Given data

number of clients = 70

travelled to England , France or both = 60

travelled to England = 45

travelled to France = 50

let:

E represent the client that visited England only,

F represent the number of client that visited France only,

EF represent the number of clients that visited both England and France only

we have

E + F + EF = 60

45 - EF + 50  - EF + EF = 60

45 + 50 - EF = 60

95 - EF = 60

95 - 60 = EF

EF = 35

E = 10

F = 15

probability

Pr = required outcome / possible outcome

= EF / clients surveyed

= 35 / 70

= 0.5

Explanation

EF represents the number of clients that visited England and France only, and it was solved to be 35. probability is the ratio of required outcome which 35 to the possible outcome which is the total number of clients 70. The ratio gives 0.5

The value of 165 pounds is 74.8 kilograms

The given parameter is:

1 kilogram = 2.205 pounds

Multiply both sides by 165

So, we have

165 * 1 kilogram = 2.205 pounds * 165

Divide both sides by 2.205

So, we have

165/2.205 * 1 kilogram = 2.205 pounds * 165/2.205

Evaluate the products

So, we have

74.8 kilogram = 165 pounds

Answer:

[tex]y\le -\frac{1}{3}x + 1[/tex]

Step-by-step explanation:

The equation of the line is y = mx + b

where

m is the slope = rise/run

b = y-intercept ie where the line crosses the y-axis at x = 0

The line crosses the y axis at y = 1 so the y-intercept is 1 and the point at which the line crosses is (0, 1)

We have the equation as

y = mx + 1

To find the slope, take any two points on the line. Find the corresponding difference in the y values and divide this difference by the corresponding difference in the x values

Two convenient points are (0, 1) and (3, 0)

Slope = [tex]\frac{0-1}{3-0} = -\frac{1}{3}[/tex]

Equation of the line :
[tex]y = -\frac{1}{3}x + 1[/tex]

The slope across the values of the table are not the same, therefore, the table cannot be modelled by a linear equation.

If a table can be represented by a linear equation, then the slope/rate of change between every two pairs of values on the table must be the same. If it's not, then it is not a linear equation that represents y as a function of x.

Slope/rate of change between (1, 18) and (2, 15):

Slope = 18 - 15/1 - 2

Slope =-3

Slope/rate of change between (2, 15) and (8, 9):

Slope = 15 - 9 / 2 - 8

The area of the shaded region in the first quadrant is: 0.75 units

The area under a curve between two points can be found by doing a definite integral between the two points.

Now,

Given:

To find: area bounded by the given lines and curve in the first quadrant.

Finding:

Now, according to the question, the lines x = 0 and y = 2 intersect at the point (0,2).

Point of Intersection of y = 2 and y = 3x - x²:

2 = 3x - x²

=> x² - 3x + 2 = 0

=> (x - 2)(x - 1) = 0

That is, the line and the curve intersect at two points: ( 1 , 2) and (2,2). But the point that is of our importance is only (1,2).
