Answer 1

Answer:

They are not similar.

Step-by-step explanation:

The angles of a triangle add up to be 180°. If they were similar, the triangle angles would have to be 60°, 40°, and 80°. Because one of the angles is 81°, the triangles cannot be similar.

81° + 40° + 60° does not equal 180.

Determine the total amount of money that was utilized on fuel in June 2022​

Answers

Therefore, the total amount of money utilized on fuel in June 2022 is R11 095,60.

What is percent?

Percent is a way of expressing a quantity as a fraction of 100. It is denoted by the symbol %, which means "per hundred". Percentages are often used to represent proportions or ratios in various fields, including finance, science, and statistics. For example, an interest rate of 5% means that for every hundred dollars borrowed or invested, five dollars of interest will be charged or earned.

Here,

(a) To calculate the total distance covered by the water tanker in March 2022, we need to find the distance travelled per day and multiply it by the number of days in March.

Distance travelled per day = 2 × 18 = 36 km (since it's a return trip)

Number of weekdays in March = 31 - 4 (Saturdays) = 27

Total distance covered = distance per day × number of weekdays

= 36 km/day × 27 days

= 972 km

(b) To determine the quantity of fuel utilized by the water tanker in March 2022, we need to divide the total distance covered by the average fuel consumption rate.

Fuel consumption rate = 5 km/ℓ

Total distance covered = 972 km

Fuel utilized = total distance covered / fuel consumption rate

= 972 km / 5 km/ℓ

= 194.4 ℓ

(c) To determine the total amount of money utilized on fuel for the water tanker in March 2022, we need to multiply the fuel quantity by the fuel price.

Fuel price in March 2022 = R16,28/ℓ

Fuel utilized = 194.4 ℓ

Total cost of fuel = fuel price × fuel quantity

= R16,28/ℓ × 194.4 ℓ

= R3 163,39

Therefore, the total amount of money utilized on fuel for the water tanker in March 2022 is R3 163,39.

(d) To determine the total amount of money utilized on fuel in June 2022, we need to repeat the above calculation using the June fuel price.

Fuel price in June 2022 = R24,14/ℓ

Fuel capacity = 460 ℓ

Total cost of fuel = fuel price × fuel capacity

= R24,14/ℓ × 460 ℓ

= R11 095,60

Emir is standing in a treehouse and looking down at a swingset in the yard next door. the angle of depression from emir's eyeline to the swingset is 33.69°, and emir is 10 feet from the ground. how many feet is the base of the tree from the swingset? round your answer to the nearest foot.

Answers

The distance from the base of the tree from the swing sets is 15 ft

The situation forms a right angle triangle.

How to find the distance from the base of the tree to the swing set?

The opposite side of the triangle formed is the distance of Emir from the ground.

Therefore, the distance from the base of the tree from the swing sets is the adjacent side of the triangle.

Hence,

tan 33.69 = opposite / adjacent

tan 33.69 = 10 / x

x = 10 / tan 33.69

x = 10 / 0.66666496431

x = 10 / 0.66666496431

x = 15.0000038265

x = 15 ft

The velocity in a fluid flow field is given by u=2x+y^2u=2x+y2 and v=3x^2yv=3x2y where uu is the x-component of velocity, and vv is the y-component of velocity. What is the x-component of fluid acceleration in terms of x and y?

Answers

The x-component of fluid acceleration in terms of x and y is 2.

To find the x-component of fluid acceleration (ax), we need to differentiate the x-component of velocity (u) with respect to time.

However, the given equations provide the expressions for u in terms of x and y, not time. Therefore, we need to differentiate u with respect to x and y instead.

Given: u = 2x + y^2

To find the x-component of fluid acceleration (ax), we differentiate u with respect to x while treating y as a constant:

ax = ∂u/∂x = ∂(2x + y^2)/∂x = 2

The x-component of fluid acceleration, ax, is simply 2.

The function f(x) is shown on the graph.

On a coordinate plane, a curved line with 3 arcs, labeled f of x, crosses the x-axis at (negative 2, 0), (1, 0), and (3, 0), and the y-axis at (0, negative 6).

If f(x) = 0, what is x?

Answers

Answer:

\(x=-2,1,3\)

Step-by-step explanation:

Given: The curved line represented by the function \(f(x)\) crosses the x-axis at \((-2,0),(1,0),(3,0)\) and y-axis at \((0,-6)\)

To find: value of x for which \(f(x)=0\)

Solution:

\(f(x)=0\) gives those values of x for which the curve represented by the given function cuts the x-axis.

According to question, the curve cuts the x-axis at \(x=-2,1,3\)

The values of x, when f(x) = 0 are the y-intercepts of the graph, and the values are -2, 1 and 3

The points on the function on the graph are given as:

\((x,y) = \{(-2,0), (1,0), (3,0), (0,-6)\}\)

In the above ordered pairs, the points where y or f(x) equals 0 are:

\((x,y) = \{(-2,0), (1,0), (3,0)\}\)

Remove the y-values

\(x = \{-2, 1, 3\}\)

The above set represents the values of x, when f(x) = 0.

Hence, the values of x, when f(x) = 0 are -2, 1 and 3

If f(x) = 2x^4, then f'(3) =

Answers

To find f'(3) (f prime of 3), you must find f' first.  f' is the derivative of the function f(x).

Finding the derivative of f(x) = 2x⁴ requires the use of the power rule.

The power rule for derivatives is \(\frac{d}{dx} [x^{n} ] =nx^{n-1}\).  In other words, you bring the exponent forward and multiply it by the coefficient of the term, and then you subtract 1 from the original exponent.

f'(x) = \(\frac{d}{dx}\)(2x⁴)

f'(x) = 2(4)x³

f'(x) = 8x³

Now, to find f'(3), plug 3 into your derivative.

f'(3) = 8(3)³

f'(3) = 216

If the letters of sassafras are randomly permuted, what is the probability that the four s's are adjacent and the three a's are adjacent?

Answers

The probability that the four s's are adjacent and the three a's are adjacent is 1/18

The total number of possible permutations of the letters in "sassafras" is 9!/(4!3!2!) = 1260, where 4! and 3! account for the permutations of the four s's and three a's, respectively, and 2! accounts for the permutations of the two remaining letters (f and r).

To calculate the number of permutations where the four s's are adjacent and the three a's are adjacent, we can consider them as a single block of seven letters: (ssssaaa). This block can be arranged in 7!/(4!3!) = 35 ways. The remaining two letters (f and r) can be placed in the remaining two positions in 2! ways.

Therefore, the number of permutations that satisfy the given conditions is 35 x 2! = 70.

The probability of selecting a permutation that satisfies both conditions is then 70/1260 = 1/18.

y = 0

Step-by-step explanation:

The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.

For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P’, the coordinates of P’ are (-5,4). Notice that the y-coordinate for both points did not change, but the value of the x-coordinate changed from 5 to -5.

You can think  of reflections as a flip over a designated line of reflection. You can often visualize what a reflection over the x axis or a reflection over the y axis may look like before you ever apply any rules of plot any points. This aspect of reflections is helpful because you can often tell if your transformation is correct based on how it looks. If the new image resembles a mirror image of the original, you’re in good shape! If it does not, you probably did something wrong.
