Solving the equation x^2 + (y- 5)^2 = 30 for isolating x^2 is x^2 = - y^2 + 10y + 5. (Option D)

Equation is a mathematical statement that expresses values of two mathematical expressions as equal and is indicated by the sign =.

In order to isolate x^2 in the equation x^2 + (y- 5)^2 = 30, the remaining terms must be solved and simplified and collected on the other side.

Given equation is:

x^2 + (y- 5)^2 = 30

Expanding the (y- 5)^2 using formula for square of the difference between the two terms.

In general form: (a – b)^2 = a^2 – 2ab + b^2

Hence,

(y- 5)^2 = y^2 – 2(y)(5) + 5^2 = y^2 – 10y + 25

The original equation becomes,

x^2 + y^2 – 10y + 25 = 30

Subtract y^2 – 10y + 25 from both sides and simplifying:

x^2 + y^2 – 10y + 25 – (y^2 – 10y + 25) = 30 – (y^2 – 10y + 25)

x^2 = 30 – y^2 + 10y - 25

x^2 = - y^2 + 10y + 5

Note: The question is incomplete as it is missing options which are A. x^2 = y^2 + 10y+5 B. x^2 =-y^2 + 10y+25 C. x^2 = 30 - y^2 D. x^2 = - y^2 + 10y+5

We can determine whether the rocket is ascending or descending by evaluating the derivative at that time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

What is a derivative of a function?

The derivative of a function can be interpreted as the slope of the graph of the function or, more precisely, as the slope of the tangent line at a point. Its calculation, in fact, derives from the slope formula for a straight line, except that a limiting process must be used for curves.

To determine whether the rocket is ascending or descending at a given time, we need to find the derivative of the function h(t) and determine whether it is positive or negative.

The derivative of h(t) is given by h'(t) = -t²+42t+43. This is the rate of change of the height of the rocket at any given time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

At t = 1 second, h'(t) = -1 + 42 + 43 = 44. Since the derivative is positive at t = 1, we know that the rocket is ascending at this time.

Hence, we can determine whether the rocket is ascending or descending by evaluating the derivative at that time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                            Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

f(x) . g(x) = f(x) . ( 11x + 7 )

Proved is shown below.

A set is a collection of items where there are operations such as:

Union of sets, the intersection of sets, complements of sets.

We have,

Consider A = {1, 2, 3, 4, 5}

B = {2, 3, 4, 6, 7}

P (A + B) = P (A U B)

P (AB) = P (A ∩ B) (Common values}

P (AB) = {2, 3, 4}

P (A + B ) = {1, 2, 3, 4, 5, 6, 7}

Now,

P(A + B) = P(A) + P(B) - P(AB)

{1, 2, 3, 4, 5, 6, 7} = {1, 2, 3, 4, 5} + {2, 3, 4, 6, 7} - {2, 3, 4}

The average speed of the trains are Bullet train = 91.4 km/hr and Ordinary train = 24.9 km/hr

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

Bullet train

Distance = 320 km

Time = 3 and half hours = 3.5

Ordinary train

Distance = 212 km

Time = 8 and half hours = 8.5

By definition, the speed of an object is the ratio of the distance moved by the object and the time travelled by the object

Mathematically, this can be represented as

Speed = Distance : Time

Express as fraction

Speed = Distance/Time

So, we have

Bullet train = 320/3.5 = 91.4

Ordinary train = 212/8.5 = 24.9

Hence, the speed of the ordinary train is 24.9 km per hour

Step-by-step explanation:

You want the graphed figure dilated by different scale factors around different center points.

To find the image of a dilated point, figure how far it is from the center of dilation, then multiply that distance by the scale factor. Plot the image point at that distance from the center of dilation in the same direction as the original point.

Dilation by a factor of 1/2 cuts all the distances in half. 2 grid squares become 1; 4 grid squares become 2.

Dilation by a factor of 2 multiplies all the distances by 2. 2 grid squares become 4; 4 grid squares become 8.

In the attached graph, the points are labeled with subscripts a, b, c according to the dilation they correspond to. Note that the center of dilation doesn't move, so Q and Q_a are the same point, and S and S_c are the same point.

If John invests $200 into an account with a 2.7% interest rate that is compounded semiannually, after 10 years he will have a future value of $261.52.

The future value is the compounded present value at an interest rate into the future.

The future value can be worked out using the FV table or formula.  We can also use an online finance calculator to find the future value of present-day investment.

N (# of periods) = 20 semiannual periods (10 years x 2)

I/Y (Interest per year) = 2.7%

PV (Present Value) = $200

PMT (Periodic Payment) = $0
