Answer:

The lengths of the two pieces are 7 cm and 14 cm.

Step-by-step explanation:

Let x represent the length of the longer piece of the rod. Since the lengths of the two pieces are in the ratio 7:2, the length of the shorter piece is 2x. The total length of the two pieces is therefore 7x + 2x = 9x. Since the total length of the two pieces is 63 cm, we have:

9x = 63

Dividing both sides by 9, we get:

x = 7

Thus, the length of the longer piece is 7 cm, and the length of the shorter piece is 2 * 7 = 14 cm. Therefore, the lengths of the two pieces are 7 cm and 14 cm.

The area under the curve r²=50sin2Θ is (15.71)unit square

A parabola is defined as a plane curve that is mirror-symmetrical and approximately U-shaped.

Given:

parabola is r²=50sin 2[tex]\theta[/tex],

where r=5

So, 5²=50 sin 2[tex]\theta[/tex],

Simplifying the equation

25=50 sin 2[tex]\theta[/tex],

sin 2[tex]\theta[/tex] = 1/2

2[tex]\theta[/tex] = [tex]sin^{-1[/tex] 0.5

[tex]\theta[/tex] = 15 degree.

Now, the Area = 22/7 × 5

Area = 15.71 unit²

Given A = rolling a number lower than 2

A six- sided bones has possible issues and 6. We also note that the only outgrowth lower than 2. probability of both issues is equal i.e. 50 or 1/2.

So, the probability of an event is Favorable issues Total number of issues. It's denoted with the gap i.e. P( Event) The possibility of the result of any arbitrary event is known as probability. This expression refers to determining the liability that any given circumstance will do. What are the chances of entering a head, for case, when we toss a coin in the air? The number of issues that could do is the base for the response to this question. The outgrowth in this case might be either head or tail. thus, there's a 50 chance that the result will be a head. The probability serves as a hand for how probably an event is to do. It gauges how likely an event is. The probability formula is as follows P( E) is equal to the rate of favourable issues to overall issues.

Answer: x=9, excluded value x≠5

Step-by-step explanation:

1. add 3 to both sides -> 16/x-5 = 4

2. then multiply both sides by x-5 -> 16=4(x-5) -> 16=4x-20

3. add 20 to both sides -> 36=4x

48 is the number does not belong in the following series 1, 2, 5, 10, 13, 26, 29, 48

The series is formed by following the sequence that is:

1, 2, 5, 10, 13, 26, 29, 48

Number pattern is a pattern or sequence in a series of numbers. This pattern generally establishes a common relationship between all numbers. A recursive pattern rule is a pattern rule that tells you the start number of a pattern and how the pattern continues.

The first number is multiplied by 2 and the next number should be added by 3 to the previous number.

The first number is 1 and it should be multiplied by 2

1 × 2 = 2

Then the next number should be added by 3

2 + 3 = 5

The series will be continued:

5 × 2 = 10

10 + 3 = 13

13 × 2 = 26

26 + 3 = 29

but 29 × 2 = 58 ≠ 48.

Answer:

------------------------------------

Given sequence:

This is an AP, with the first term a = 15 and common difference of - 3, as it is decreasing by 3.

Use nth term equation for an AP:

The value of x we get from the equation is [tex]\frac{- 10 ±\sqrt{208}}{18}\\[/tex]

The given equation is [tex]9x^{2} + 10x -3=0[/tex]

We know, the quadratic formula is [tex]x=\frac{-b ± \sqrt{b^{2}-4ac}}{2a}[/tex] where [tex]a\neq 0[/tex]

Using the Quadratic Formula where

a = 9, b = 10, and c = -3

We get,

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

[tex]x=\frac{- 10± \sqrt{10^{2}-4(9)(-3) }}{2(9)}\\[/tex]

[tex]x=\frac{- 10± \sqrt{100--108 }}{18}\\[/tex]

[tex]x=\frac{- 10± \sqrt{208}}{18}\\[/tex]

The discriminant [tex]b^{2} -4ac[/tex]>0 so, there are two real roots

2) put these value in the formula, then we will get

  here, a=9

            b=10

            c=-3

  x=-10±√100-4*9*-3÷2*9

  x=-10±√208÷18

The value of the discriminant of f is 0.

There is one distinct real number of zeroes.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 3x² + 24x + 48

This is in the form of ax² + bx + c

a = 3

b = 24

c = 48

The discriminant is given by b² - 4ac.

There are two real solutions when it is greater than 0.

There is one real solution when it is equal to 0.

There are two imaginary solutions when it is less than 0.

Now,

= 24² - 4 x 3 x 48

= 576 - 576

= 0

So,

There is one real solution.

Thus,

The value of the discriminant of f is 0.

Y axis: now you do the "jumping" portion of this, so you jump up six units as it's a negative, so now your on (3, 6) (red arrows)

Y: axis: but now you have to move down 1 unit, so you essentially "fall" 1 unit down, (3, 5) (pink arrow)

Y axis:  you have to "jump" 4 units up now, so now your at (3, 9) (green arrows)

[tex]x^{2} - 36 = x^{2} - 6^{2} = (x-6)(x+6)[/tex]

To simplify this equation, quadratic factoring patterns should be used. These patterns are the following:

This pattern works because if one distributes the terms in the parentheses by multiplying each term in one of the parentheses by each term in the other, the result is the original equation:

The total amount of interest that Maria will owe on her unsubsidized loan = $113.63

In this question we have been given Maria received a $5,000 subsidized loan and a $4,500 unsubsidized loan with an apr of 5.05%

We need to find the total amount of interest that Maria will owe on her unsubsidized loan.

Using simple interest formula,

I = P * t * r

where P - the principal

r - the interest rate,

and t - time period

Maria  begins making payments 6 months after graduation, this means there are 12 - 6 = 6 months between graduation and the start of payments.

so, t = 6 months

i.e., t = 0.5 year

Here, R = 5.05%, P = $4500

Now we convert R percent to r a decimal

r = R/100

 = 5.05%/100

 = 0.0505 per year,

Using the formula of simple interest,

I = 4500 * 0.0505 * 0.5

I = $113.63

Therefore, the interest amount is $113.625

Any multiple of 5 will always have a 5 or 0 in it. If it doesn't have a zero in it anywhere it is not divisible by 10. A multiple of 10 will always have a zero in it.

The equation of a circle with center  (1,-2) and radius 2 is ( x - 1 )² + ( y + 2 )² = 4.

The standard form of the circle is x² + y² = r²

Where r is the radius.

h and k is the horizontal and vertical translation which represent the center of the circle..

Hence, the formula is derived from the distance formula where the distance is between the center and every point on the circle is equal to the length of the radius.

( x - h )² + ( y - k )² = r²

Given that;

Center: (1,-2)

Plug the given values into the equation and simplify.

( x - h )² + ( y - k )² = r²

( x - 1 )² + ( y - (-2) )² = 2²

( x - 1 )² + ( y + 2 )² = 2²

( x - 1 )² + ( y + 2 )² = 4
