Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Originally our equation looks like [tex]x^{2}[/tex] + 2y

First, we want to substitute x = [tex]\frac{1}{2}[/tex]  & y= 0 into the equation.

The equation now looks like [tex]([/tex][tex]\frac{1}{2}[/tex][tex])^{2}[/tex] + 2 x 0

The brackets are added to the fraction as we are squaring the WHOLE fraction, and the 2y has a hidden multiplication sign, with it being 2 x y, so it is 2 x 0.

Now that we have our values substituted into the equation, we can solve it!

 [tex]([/tex][tex]\frac{1}{2}[/tex][tex])^{2}[/tex] = [tex]\frac{1}{4}[/tex]  

therefore,

[tex]\frac{1}{4}[/tex]  + 2 x 0

= [tex]\frac{1}{4}[/tex]

The two numbers that can be true for the equations are 5 and 12

From the information given, we have the equations;

x+y=17

x-y=7

From equation (1), make 'x' the subject of formula

x = 17 - y

Now, substitute the value into the formula, we have;

17 - y - y= 7

collect like terms

-y-y = 7 - 17

Subtract the iike terms

-2y = -10

Make 'y' the subject

y = 5

Substitute the value

x = 17 -5

x = 12

Hence, the values are 12 and 5

Answer:

MN ≈ 92.1

Step-by-step explanation:

given the figures are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{MN}{IJ}[/tex] = [tex]\frac{KL}{GH}[/tex] ( substitute values )

[tex]\frac{MN}{21}[/tex] = [tex]\frac{57}{13}[/tex] ( cross- multiply )

MN ≈ 92.1 ( to the nearest tenth )

Answer: a. To create the graph, we need to find the speed (in km/min) of Lin and Andre. The speed is calculated as distance divided by time.

For Lin: speed = 1.5 km / 5 min = 0.3 km/min

For Andre: speed = 2 km / 8 min = 0.25 km/min

We can plot these speeds as points on a graph with time on the x-axis and speed on the y-axis.

b. The point for Lin is (5, 0.3) and for Andre is (8, 0.25).

c. From the graph, we can see that Lin was biking faster, with a speed of 0.3 km/min compared to Andre's speed of 0.25 km/min.

Step-by-step explanation:

KE = (1/2) * m * v^2

where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

We are given the mass of the bumblebee as 0.015 kg and its velocity as 21.0 m/sec. We can plug these values into the formula to calculate its kinetic energy:

KE = (1/2) * m * v^2

= (1/2) * 0.015 kg * (21.0 m/sec)^2

= (1/2) * 0.015 kg * 441.0 m^2/sec^2

= 2.92625 J

Therefore, the bumblebee has 2.92625 Joules of kinetic energy as it hits the windshield.

Answer:

The kinetic energy of the bumblebee as it hits the windshield is given by the equation KE = 0.5 x 0.015 kg x (21.0 m/s) squared. This gives us a total of 945 J of kinetic energy.

Answer: To find the highest common factor (HCF) of two polynomials, we can use the Euclidean algorithm for polynomials. The Euclidean algorithm involves dividing the larger polynomial by the smaller polynomial and continuing the division process until the remainder is zero. The last non-zero remainder is the HCF of the two polynomials.

In this case, we have:

2x^3 + x^2 - 3x = (2x^3 - x^3) + x^2 - 3x

= x^3 + x^2 - 3x

Now, we divide x^3 + x^2 - 3x by x^3 - x

x^3 + x^2 - 3x = x^3 - x * (1 + x - 3)

= x^3 - x * (x^2 - 2x + 3)

We cannot simplify this expression further, so the HCF of 2x^3 + x^2 - 3x and x^3 - x is x^3 - x.

Answer:

She should walk at a rate of 16 km/hr

Step-by-step explanation:

At a rate of 12 km/hr, she would have traveled 4 km in 20 minutes. This can be calculated by finding the ratio of 20 minutes to 1 hour which is 1/3. We then multiply this ratio by the rate to find the distance Shalu needs to walk to school.

We then need to find the necessary km/hr in order for Shalu to travel 4 km in 15 minutes. 15 minutes is a quarter of 1 hr. Therefore a rate of 4 km/15 minutes is equal to a rate of 16 km/hr. This means that the average speed Shalu would have to walk is 16 km/hr.

The measure of the angle ∠PSR will be equal to 25 degrees.

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that In quadrilateral PQRS, the exterior angle at Q when PQ is extended measures 155 and PS = QR.

The measure of the angle PSR will be calculated as:-

∠Q exterior  = 155

∠PQR = 180 - 155

∠PQR = 25

Answer: 36cm

Step-by-step explanation:

The value of "n" is approximately 2.6666667.

Exponent is a mathematical operation that represents repeated multiplication of the same number.

We can start by simplifying the left side of the equation:

(2^(2n))^4 * (2^n)^2 = 2^16 - 1

Using the exponent rules:

a^m * a^n = a^(m + n)

We can simplify the left side of the equation further:

2^(4n + 2n) = 2^16 - 1

Combining the exponents:

2^(6n) = 2^16 - 1

Now we can use the fact that if a^m = a^n, then m = n to solve for "n":

6n = 16

Dividing both sides by 6:

n = 16/6 = 8/3

Therefore, The value of "n" is approximately 2.6666667.

Applying the secant-secant theorem, the value of x is: 12.

The secant-secant theorem states that if you draw two lines from a point outside a circle that intersect the circle at two different points, then the product of the length of one line segment and the length of the portion of the line outside the circle is equal to the product of the length of the other line segment and the length of its portion outside the circle.

Based on the secant-secant theorem, we have:

EF * ES = ED * EC

Substitute the values:

8(8 + 10) = 9(2x - 17 + 9)

Solve for x:

144 = 18x - 72

Answer:

10+5v=70

Step-by-step explanation:

this is because you need to consider the outright monthly cost of $10 first. then you don't know how many visits you'll need so you have to fill in v and multiply it by the cost per visit. and it must equal 70 so that it is equal to the other membership.

The equation 70 = 10 + 5v is used to determine the number of visits per month needed for two membership types to cost the same. Solving the equation would provide that 12 visits a month will make both memberships cost the same.

The subject of this question is Mathematics, and it is related to the topic of linear equations. Given the problem, we know that there are two types of membership options:

Here, Y represents the total cost of the membership each month and v represents the number of visits to the water park per month. You can set these two equations equal to each other in order to find the number of visits (v) needed for the two membership types to cost the same amount:

70 = 10 + 5v

You solve the equation for v to get: v = (70 - 10) / 5 = 12

Therefore, it would take 12 visits per month for both memberships to cost the same.

For rectangle ABCD, the value of x is 6.44 inches

Consider the following diagram.

From this figure we can observe that the dimansions of the rectangle: length is given by expression (7x + 1) and width is given by expression 'x'

We know that tha formula for the perimeter of the rectangle,

P = 2 × (length + width)

Here, the perimeter of rectangle ABCD is 105 inches.

Using above formula of perimeter we get an expression,

P = 2 × ((7x + 1)+ x)

Let's call the number of candles Roma sold for $5 each "x".

What is the unitary method's formula?

What is the unitary method's formula? The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.

Since she sold 200 candles in total, we know that x + 3y = 200, where y is the number of sets of three candles she sold for $11.

We also know that the total revenue was $788, so we can set up another equation based on the total revenue:

5x + 11y = 788

Now that we have two equations, we can use substitution to solve for x. First, let's solve for y:

y = (200 - x) / 3

Plugging this expression for y into the second equation:

5x + 11((200 - x) / 3) = 788

Expanding and simplifying the equation:

5x + (2200 - 11x) / 3 = 788

Multiplying both sides by 3 to get rid of the fraction:

15x + 2200 - 11x = 2364

Combining like terms:

4x = 164

Finally, dividing both sides by 4 to solve for x:
