Answer:

t=1/2u

Step-by-step explanation:

Since t=tens digit and u=units digit, as given in the equation that means that t+u=9. Since the tens digit is one-half the units digit that means: [tex]t=\frac{1}{2}u[/tex] since it's one half the units digit.

The largest number of different whole numbers that can be on Zoltan's list is 999

The condition is given as:

Number =  1/3 of another number

Or

Number = 3 times another number

This means that the list consists of multiples of 3

The largest multiple of 3 less than 1000 is 999

Hence, the largest number of different whole numbers that can be on Zoltan's list is 999

PR*RT = QR*RS

4*15 = 5*RS

60 = 5*RS

RS = 60/5

RS = 12

For more information, check out the intersecting chords theorem. This is the idea where multiplying pieces of two chords leads to the same product.  A chord is any segment where both endpoints are on the edge of the circle.

RS is equal to 12.

In a circle, two chords that intersect inside of a circle is given by this formula: PR * RT = QR * RS

Since these two chords are equal, we can set up this equation by putting what we know so far. Since PR * RT = 15 * 14 = 60, and QR * RS = 5 * RS, we get 5 * RS = 60. This is just a simple algebraic expression now.

Dividing by 5 from both sides, we get [tex]\frac{RS}{5}[/tex] = [tex]\frac{60}{5}[/tex].

We then get RS = 12. This wasn't so bad, right?

The solutions for the given equation [tex]4x^2+x-3=0[/tex] are x = -1 and x = 3/4. Using the quadratic formula, the solutions for the given equation are calculated.

The formula which is used to calculate the roots(solutions) of the quadratic equation in the form [tex]ax^2+bx+c=0[/tex] is

x = [- b ± [tex]\sqrt{b^2-4ac}[/tex]]/2a

The given equation is [tex]4x^2+x-3=0[/tex]

In comparison with the standard form of quadratic equation [tex]ax^2+bx+c=0[/tex],

we get, a = 4, b = 1 and c = -3

So, solving the given equation using the quadratic formula,

x = [- b ± [tex]\sqrt{b^2-4ac}[/tex]]/2a

  = [- 1 ± [tex]\sqrt{1-4(4)(-3)}[/tex]]/2(4)

  = [-1 ± [tex]\sqrt{49}[/tex]]/8

  = (-1 ± 7)/8

Thus, x =  (-1 + 7)/8 = 3/4 and x = (-1-7)/8 = -8/8 = -1

Therefore, the solutions of the given equation are x = -1 and x = 3/4.

The equation in rectangular coordinates. (x - 1)² + y² = 1

There are many types of coordinate system depending upon the usage and ease of working , Spherical , Rectangular , Cylindrical , Polar are the examples of Coordinate System.

It is given that the equation in polar coordinates is  r = 2 cosθ

To change in rectangular coordinates

The relation between polar and rectangular coordinate is

x = r cosθ and y = r sinθ

x² + y² = r²

r = 2 cosθ

r² = 2r cosθ

r² = x

so the equation in rectangular coordinate system becomes

x² + y² = 2x

x² - 2x + y² = 0

x² - 2x + 1 + y² - 1 = 0

(x - 1)² + y² = 1

Answer:

Step-by-step explanation:

The angle sum theorem helps you compute the angle inside the triangle. The inscribed angle theorem helps you compute the arc measures outside the triangle.

The Angle Sum theorem tells you the sum of angles in a triangle is 180°. That lets you write the equation ...

  X +Y +Z = 180°

  X +69° +41° = 180°

The Inscribed Angle theorem tells you an inscribed angle has half the measure of the central angle subtending the same arc. The arc and the central angle have the same measure: twice that of the inscribed angle.

  arc ZY = 2×∠X

  arc XY = 2×∠Z

Using the equations we wrote describing the relationships of the unknowns to the known information, we find ...

  X = 180° -110° = 70°

  arc ZY = 2×70° = 140°

  arc XY = 2×41° = 82°

Answer:Angle x=70°

Step-by-step explanation:interior angles add up to 180° so we add 41° and 69°. After addition,you minus from 180° and you get 70°

[-2.5, -2], [-2, -1.5], [1.5, 2] and [2, 2.5) were the  intervals show f(x) decreasing

A relation is a function if it has only One y-value for each x-value.

To find the intervals where a function is decreasing, you need to look for the parts of the function where the slope is negative.

In other words, you need to find the intervals where the function is going downhill.

By the given function or graph the intervals where f(x) is decreasing are

[-2.5, -2], [-2, -1.5], [1.5, 2] and [2, 2.5)

Hence, [-2.5, -2], [-2, -1.5], [1.5, 2] and [2, 2.5) were the  intervals show f(x) decreasing

Answer:

True, False, False, False

Step-by-step explanation:

I'll find the lengths of all sides of the drawing before answering individual answers so that it's less confusing.

1) The question says that QR is a perpendicular bisector of TS. This means that the length of TQ and QS is the same. Also, since both triangles TRQ and SRQ share the same side RQ, and the angle between the two segments is 90 degrees, the two triangles are congruent (RTQ and RSQ) using SAS.

2) Side RT and TS will have the same length since the two triangles are congruent. (2x+1) = (4x-3) --> -2x = -4 --> x = 2. We can conclude that x = 2.

3) Now that we know that x = 2, we can find the length of side RS by replacing the x with 2. 4(2)-3 is 5, so RS = 5.

4) We can use the Pythagorean theorem to find RQ (Hypotenuse^2 = Other two sides added after being squared individually). Since the hypotenuse of triangle RSQ is RS which is 5, and one side is 4, we can input those into our equation. (5)^2 = (4)^2 + (RQ)^2. --> 25 = 16 + (RQ)^2 --> 9 = (RQ)^2 --> RQ = 3.

5) Since the two triangles RTQ and RSQ are congruent, side TQ and SQ also have the same length, since CPCTC (Corresponding parts of congruent triangles are congruent). QS is 4, so TQ will also be 4. This means that ST will be 8 (4+4). ST = 8

Now that we have all the clues, all we need to do is choose True or False.

RS = 5 is TRUE

RS = 4 is FALSE

ST = 10 is FALSE

QR = 4 is FALSE

The probability that a random variable has a particular value or a range of values is the sum of the probabilities associated with each of the values.

All of the x-values in the table are less than or equal to 20, so p(x≤20) is the sum of all of the probabilities in the table.

  p(x≤20) = 0.20 +0.15 +0.05 +0.1 +0.25 +0.1 +0.15 = 1.00

Answer:

It will take 1 hour and 24 minutes.

Step-by-step explanation:

Given that:

Eastbound train travels at a rate of 65 miles per hour and Westbound train travels at a rate of 85 miles per hour

So speed = 65 + 85 = 150 miles per hour

Total distance = 210 miles

We have to find the time, we know that

Distance = time * speed

OR

Time = distance / speed

Time = 210/150

Time = 1.4 hours

Or it can be written as:

Time = 1 hour 24 minutes

Answer: 1/2, 15/2

Step-by-step explanation:

to solve this absolute value equation, all you need to do is divide the 2 over to the other side of the equation, giving:

|4-x|=7/2

and then you can remove the absolute value symbols and make 2 equations:

4-x=7/2

4-x=-7/2

solve these and you're done!

Answer:

y=-4 and y=-8

Step-by-step explanation:

When you have an absolute value around something, you can remove it, expect it's like a square root, it's going to be a [tex]\pm[/tex]. Because 6+y could've been -2 and the absolute value just made it positive 2

So set 6+y equal to -2 and 2 to find the two solutions:

6+y = 2

y = -4

6+y = -2

y = -8

Hey there!

YOUR EQUATION: |6 + y| = 2

CONVERT THAT TO:

y + 6 = 2 OR y + 6 = -2

FIRST let’s solve for: y + 6 = 2

y + 6 = 2

SUBTRACT 6 to BOTH SIDES

y = 6 - 6 = 2 - 6

SIMPLIFY THAT!

y = 2 - 6

y = -4

Possible solution #1: y = -4

LASTLY let’s solve for: y + 6 = -2

y + 6 = -2
SUBTRACT 6 to BOTH SIDES

y + 6 - 6 = -2 - 6

SIMPLIFY THAT AS WELL!

y = -2 - 6

y = -8

Possible solution #2. y = -8

Therefore, your answer should be:

y = -4 or y = -8

a. Fails in less than 10,000 hours.

P(X < 10,000) = 1 - e^-λx
