Answer:

P(A) =0.5 obviously since it didn't say like P(AC) or P(AD)

Answer:(29.85km/h)

Step-by-step explanation:

1000m=1km

200m=x  [x=(200m/1000m)x1km]

x=0.2km

3600second= 1 hour  

24 seconds =b   [b=(24s/3600s)x1 hour ]

b=0.0067(in 2 decimal place)

velocity in km/h will be

0.2km/0,0067secs

=29.85(in 2 decimal place)

Answer:

speed = 30 km/h

Step-by-step explanation:

We are told that a 200 metres race is run by an athlete in 24 seconds. The question then asks us to calculate the athlete's speed in km/h.

To do this, let's first convert the given data into the required units:

• Converting from metres to kilometres:
To convert from 200 metres to kilometres, we have to divide it by 1000:

200 m = 200 m ÷ 1000 m/km

           = 0.2 km

• Converting from seconds to hours:
To convert 24 seconds to hours, we have to divide it by 3600:

24 s = 24 s ÷ 3600 s/h

        = [tex]\frac{24}{3600}[/tex] h

Now that we have the data in the appropriate units, we can use the following formula to calculate speed:

[tex]\boxed{\mathrm{speed = \frac{distance}{time}}}[/tex]

⇒ speed = [tex]\mathrm{\frac{0.2 \ km}{24/3600 \ h}}[/tex]

⇒ speed = 30 km/h

Therefore, the speed of the athlete is 30 km/h.

Step-by-step explanation:

you devide the upper half of a fraction with the part under it. for example

6x2+x+1

_______=6. that is asymptote

x2+2

when you multiply 6 and lower half of a fraction you get 6x2+12

if you substract that from 6x2+x+1 you get x-11

if you make x-11=0 the number that x represents is the point where the function crosses the asymptote

The required straight equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).

What are equations in a straight line?

A straight line's equation is given by y=mx+c, where c is the height at which the line intersects the y-axis (often referred to as the y-intercept) and m is the gradient.

According to the given graph,

We can see two points are (-5, 0) and (5, 2)

The linear equation will be: y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Here

x₁ = -5, y₁ = 0

x₂ = 5, y₂ = 2

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]

Substitute values in the equation, we get

⇒ y - 0 = (2 - 0)/(8-4)(x-(-5))

⇒ y - 30 = (2)/(-4)(x + 5)

⇒ y - 30 = -1/2(x + 5)

⇒ y = (-1/2)x - 5/2 + 30

⇒ y = -0.5x + 27.5

Thus, the required equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).

Write an equation for the graph shown in the form y=ax+b.

The transformations from the parent function are

From the question, we have the following parameters that can be used in our computation:

g(x) = -|x + 3| - 4

The above function is an absolute value function

Next, we plot the graph using a graphing calculator

See attachment for the graph

From the question, we have the following function that can be used in our computation:

f(x) = |x| --- the parent function of an absolute value function

g(x) = -|x + 3| - 4 -- the transformed function

First, we have the transformation to be:

From f(x) = |x| to f'(x) = |x + 3|

This means the function is translated left by 3 units

Next, we have:

From f'(x) = |x + 3| to f'(x) = -|x + 3|

This means the function is reflected across the x-axis

Lastly, we have:

From f'(x) = -|x + 3| to g(x) = -|x + 3| - 4

This means the function is translated down by 4 units

The simplified expression, when using the Quotient rule is b. 1 / 8⁴.

The Quotient Rule allows us to be able to carry out operations on quotients. The rule is such that when dividing quotients with the same base, you should subtract the quotients. For multiplication, you add the quotients.

8 ⁵ / 8 ⁹ will therefore be:

= 8 ⁵ ⁻ ⁹

Time ∝ 1/Speed

Time = k/Speed

k = Time x Speed

The time taken for the trip for the car moving at 30 mph is 12 hours.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 7 is an equation.

We have,

Time ∝ 1/Speed

This can be written as,

Time = k/Speed

k = Time x Speed

Now,

The trip takes 8 hours for a car moving at 45 mph.

This means,

k = 8 x 45

k = 360

Now,

The time taken at the speed of 30 mph.

Time = k / Speed

Time = 360/30

Time = 12 hours

What is a line graph?

An informational shift over time is graphically represented by a line graph. It is a graph that was created by connecting points with line segments.

Michael starts with 40 bags of cucumbers and gives out 8 bags per hour until there are none left.

Michael starts giving them away until he has no bags left.

To create the graph we need coordinate points to locate on the graph.

So initially he has 40 bags and gives away 8 bags for every 1 hour.

The number of bags will be represented on the y-axis, and the number of hours will be represented on the x-axis.

The coordinates are:

x-axis           y-axis

  0                 40

  1                  32

Answer:

x = 40°

y = 35°

Step-by-step explanation:

Let us take two triangles ∆ABC and ∆ADE

We know that, in a triangle the sum of all angles is equal to 180°

So,

For the traingle ABC

Now,

m∠A + m∠B + m∠C = 180°

80° + 60° + x° = 180°

140° + x° = 180°

x° + 140° - 140° = 180° - 140°

x = 40°

For the triangle ADE

Now,

m∠A + m∠D + m∠E = 180°

80° + 65° + y° = 180°

145° + y° = 180°

y° + 145° - 145° = 180° - 145°

y = 35°

Thus, The value of x and y is 40° and 35° respectively

The slope of the line that contains the points: (-7, 8) and (12, 8) is 0

From the question, the points are given as

(-7, 8) and (12, 8)

Rewrite the above points properly

So, we have the following ordered pairs

(x, y) =  (-7, 8) and (12, 8)

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) =  (-7, 8) and (12, 8)

Substitute the known values in the above equation

So, we have the following equation

Slope = (8 - 8)/(12 + 7)

What is Exterior angle theorem?

The exterior angle theorem describes the connection between the two remote angles in a triangle and the external angle created by an extended side outside the triangle.

Given: Measure of angle YWX = (3x + 17) °

Measure of angle WXY = (3x + 2) °

Measure of angle XYZ = (10x − 5) °

Therefore, m∠XYZ = m∠YWX + m∠WXY (exterior angle theorem)

⇒ (10x − 5) ° = (3x + 17) ° + (3x + 2) °

Solve for x,

⇒ 10x - 5 = 3x + 17 + 3x + 2

⇒ 10x - 6x = 17 + 7

⇒ 4x = 24

⇒ x = 6

∴ ∠WXY = (3x + 2) = 18 + 2 = 20

In this problem we have an implicit function of the form f(x, y) = 0, whose first derivative shall be found by implicit differentiation. Now we proceed to present the procedure. First, write the entire expression:

2 · x² + 8 · x · y + 6 · y² + 13 · y - 2 = 0

Second, use the derivative rules:

4 · x + 8 · y + 8 · x · y' + 12 · y · y' + 13 · y' = 0

4 · x + 8 · y + (8 · x + 12 · y + 13) · y' = 0

y' = - 4 · (x + 2 · y) / (8 · x + 12 · y + 13)

The same procedure is used in the next two implicit functions:

3 · x³ = 2 · y² - 9 · y

9 · x² = 4 · y · y' - 9 · y'

9 · x² = (4 · y - 9) · y'

y' = 9 · x² / (4 · y - 9)

The value of the iterated integral is equal to 24. In general, when evaluating iterated integrals, it is important to remember to integrate with respect to the outer variable first, and then with respect to the inner variable. This will ensure that the resulting value of the integral is correct.

To evaluate this iterated integral, we need to integrate with respect to the outer variable first, and then with respect to the inner variable. In this case, the outer variable is x and the inner variable is y.

We can write the iterated integral as:

∫₀² ∫₂³ xy² dx dy

To find the value of this integral, we first need to evaluate the inner integral with respect to x. We can do this by taking the integral of xy² with respect to x from 0 to 2, which gives us:

∫₀² xy² dx = [x³y² / 3]₀² = (2³ * 3²) / 3 = 24/3

Now that we have found the value of the inner integral, we can evaluate the outer integral with respect to y. We can do this by taking the integral of 24/3 with respect to y from 2 to 3, which gives us:

∫₂³ (24/3) dy = [24y / 3]₂³ = (24 * 3) / 3 = 24
