Solving the expression 35.1 = 12.9 + 10.2x gives x to be 2 3/17

A group of numbers or variables coupled with the operations +, -,, or form an expression.

Algebraic expressions with variables, numbers, and mathematical operators, as opposed to arithmetic expressions that simply contain numbers and mathematical operators.

The given algebraic expression is 35.1 = 12.9 + 10.2x

Answer:

  See attached

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.

Answer:

The correct answer is (1, -3).

Step-by-step explanation:

To solve this question, we should use substitution. This means we can substitute the value given for y (as indicated by the second equation) into the first equation. This is shown below:

4x + y = 1

4x + (x - 4) = 1

We simplify the left side of the equation and then solve for x.

5x - 4 = 1

5x = 5

x = 1

We must also solve for y. To do this, we can plug in x = 1 into either of the given equations.

y = x - 4

y = 1 - 4

y = -3

Therefore, x = 1 and y = -3. The question asks us to express the answer as an ordered pair (x,y), so the answer is (1, -3).

Step-by-step explanation:

The value of the annuity due is $39,744.59.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = [tex]P\frac{(1 + r)^n -1(1+ r)}{r}[/tex].

Where, A = amount, P = principle, r = rate, and n = time in years.

Given, r = 10% semiannually so it is (10/2) = 5% or 0.05 and n = 8×2 = 16.

∴ A = [tex]1600\frac{(1 + 0.05)^{16} -1(1+ 0.05)}{0.05}[/tex].

A = [tex]1600\frac{(1.05)^{16} -1(1.05)}{0.05}[/tex]

A = [tex]\frac{1600(2.18 -1.05)}{0.05}[/tex].

A = (1600×1.13)/0.05.

The Method of Cylindrical Shells will be used to assist.

As previously, we construct a region R that is enclosed on the top by the graph of the function y = f (x), on the bottom by the x axis, and on the left and right by the lines x = a and x = b, respectively (a).

As seen in Figure 1, we then rotate this region around the y-axis (b). Be aware that this is distinct from what we have previously done..

Previously, areas that were described in terms of x-functions were centered on the x-axis or a line that ran parallel to it.

Since the shell is a cylinder, its volume equals the cross-sectional area times the cylinder's height. The cross-sections are annuli, which are essentially circles with holes in the middle and are formed like rings.

According to our question-

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

The circumference of the given circle with the diameter 27.6 yards is 86.7 yards.

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center. A meridian is any great circle passing through a point designated a pole.

Given that, the diameter of circle is 27.6 yards

Radius of a circle is the distance from the center of the circle to any point on it's circumference and radius of a circle is half of Diameter.

That is, radius =Diameter/2

So, radius of circle =27.6/2 =13.8 yards

We know that, the circumference of the circle is 2πr

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.

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)
