Answer:

a = 34

b = 34

c = 36

Step-by-step explanation:

a ; b ; c = consecutive numbers =>

b = a + 1

c = a + 2

a + 2b + c - 7 = 133

a + 2(a + 1) + (a + 2) - 7 = 133

a + 2a + 2 + a + 2 - 7 = 133

4a = 133 + 7 - 4

4a = 136

a = 34

b = 34

c = 36

Answer:

A rectangular array of numbers arranged in horizontal and vertical lines enclosed between round or square brackets is called a matrix.

Types of Matrix

According to order of matrix or value of elements,we can classify the matrices. some of the types of matrices are as follows:

A matrix having only one column is called a column Matrix.

A matrix having only one row is called row matrix.

A matrix having the numbers of rows equal to the numbers of column is called the square matrix.

A matrix having the number of rows not equal to the number of column of a matrix is called the rectangular matrix.

A matrix of any order in which each element is zero is called the null matrix( zero matrix).

A square matrix in which all the elements of leading diagonal are non-zero and the rest of the elements are zero is called a diagonal matrix.

A diagonal matrix in which all the elements of leading diagonal are 1(unit) is called unit matrix.

A diagonal matrix in which all the element of leading diagonal are equal is called scalar matrix.

A square matrix having all the elements below the diagonal and above the diagonal zero is called triangular matrix.

A square matrix is called a symmetric matrix, if it's

(i,j) th element is equal to its (j,i) th elemnent.

A square matrix B=b ij is called a skew- symmetric matrix if it's (i,j) th element is negative of its ( j, i) th element.

Two matrices are said to be equal if they have same order and corresponding elemnents of both matrices are equal.

Answer:

2 ≤ x ≤ 5

Step-by-step explanation:

If x = number of days worked

According to the question:

Employees cannot work for more than 5 days per week: that is maximum working days per week is 5 - - - (1)

x ≤ 5 - - - (1)

Employees cannot work for less Than 2 days per week, that is minimum working days per week is 2 days

x ≥ 2 - - - (2)

Combining both conditions (1) and (2) such that the both Inequality sign are the same :

If x ≥ 2 ; then 2 ≤ x

Combining 2 ≤ x and x ≤ 5

Answer:

15 cm.

Step-by-step explanation:

It is given that,

Central angle [tex]=\dfrac{7\pi}{10}[/tex]

Arc length = 33 cm

Formula for arc length :

[tex]s=r\theta[/tex]

where, s is arc length, r is radius and [tex]\theta[/tex] is central angle in radian.

Substitute s=33 and [tex]\theta=\dfrac{7\pi}{10}[/tex] in the above formula.

[tex]33=r\left(\dfrac{7\pi}{10}\right)[/tex]

Multiply both sides by 10.

[tex]330=7\pi r[/tex]

Divide both sides by [tex]7\pi[/tex].

[tex]\dfrac{330}{7\pi}= r[/tex]

Put [tex]\pi=3.14[/tex]

[tex]\dfrac{330}{7(3.14)}= r[/tex]

[tex]15.0136= r[/tex]

[tex]r\approx 15[/tex]

Therefore, the radius of the circle is 15 cm.

Answer:

Step-by-step explanation:

Answer:

a = 6, b = 8, and c = 10.

Step-by-step explanation:

You can easily use the Pythagorean Theorem to solve all of these.

a = 4; b = 6; c = 8... 4^2 + 6^2 = 16 + 36 = 52. 8^2 = 64. 52 is not equal to 64, so the first choice is not a right triangle.

a = 6; b = 8; c = 10... Well this is a multiple of the 3-4-5 Pythagorean triple, so this is a right triangle.

a = 5; b = 6; c = 761... 5^2 + 6^2 = 25 + 36 = 61. 761^2 = 579121, which is not equal to 61, so the third choice is not a right triangle.

a = 6; b = 9; c = 12... 6^2 + 9^2 = 36 + 81 = 117. 12^2 = 144, which is not equal to 117, so the fourth choice is not a right triangle.

The only case where there is a right triangle is the second choice, where a = 6, b = 8, and c = 10.

Hope this helps!

The quadrants are numbered from top right in a counter clockwise fashion. Since we know x is positive and y is negative, we can find that it is the fourth quadrant.

Answer:

D

Step-by-step explanation:

Let's call the width of the yard x and the length x + 3½. Since we know that perimeter = 2 * (width + length) and that the perimeter must be 26 we can write:

2 * (x + x + 3½) = 26

x + x + 3½ = 13

2x + 3½ = 13

2x = 9½

x = 4[tex]\frac{3}{4}[/tex]

Answer:

The correct answer is D.

Step-by-step explanation:

To solve such problems we need to know about similar figures.

Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sides are in ratio. It is denoted by the symbol "[tex]\sim[/tex]".

Given to us,

1.)  [tex]\angle G\cong\{?\}[/tex]

As we know for a similar figure the corresponding angles are equal. therefore,

[tex]\angle G\cong\angle A[/tex], as they are the corresponding angle for the two figures.

2.)  [tex]\dfrac{GF}{FD}=\dfrac{AE}{\{?\}}[/tex]

Let's assume that the unknown side is x.

As we know for a similar figure the corresponding sides are in ratio. therefore,

[tex]\dfrac{GF}{FD}=\dfrac{AE}{X}\\\\\dfrac{GF}{FD}=\dfrac{AE}{ED}[/tex]

Answer:

x = 1 or x = -5

Step-by-step explanation:

Solve for x:

x^3 + 3 x^2 - 9 x + 5 = 0

The left hand side factors into a product with two terms:

(x - 1)^2 (x + 5) = 0

Split into two equations:

(x - 1)^2 = 0 or x + 5 = 0

Take the square root of both sides:

x - 1 = 0 or x + 5 = 0

Add 1 to both sides:

x = 1 or x + 5 = 0

Subtract 5 from both sides:

Answer:  x = 1 or x = -5

Answer:

9) 1/2 (or 1:2, or 50%, or .50, depending on how your teacher wants it.

10) 2/3 (or 2:3, or 66.6%, or 0.66)

Step-by-step explanation:

9) Here are the possibilities of the cards you could pick

KQ, KJ, K10, QJ, Q10, J10

Since there are 6 possibilities and only 3 of them have one face card, the probability is 3/6, or 1/2.

10) It doesn’t matter which card you pick first.  The second card has a 1 in 3 chance of being the same card (whatever it is).  That means you have a 2 in 3 chance of it NOT being the same card.  So the probability is 2/3.

Answer:

Option B.

Step-by-step explanation:

It is given that erza is training for a track race. He starts by sprinting 100 yards. he gradually increases his distance, adding 5 yards a day for 21 days.  So, the required sequence is

100, 105, 110, 115, ...

It is an AP. Here,

First term = 100

Common difference = 5

Explicit formula for an AP is

[tex]a_n=a_1+(n-1)d[/tex]

where, [tex]a_1[/tex] is first term and d is common difference of the AP.

Substitute [tex]a_1=100\text{ and }d=5[/tex] in the above formula.

[tex]a_n=100+(n-1)5[/tex]

Therefore, the required explicit formula is [tex]a_n=100+(n-1)5[/tex].

Hence, option B is correct.

Answer:

A) tan(45°) help us to find the height of the tree because it relates our unknown with a known length (the length of the shadow)

B) tan(45°) = x/35.6

C) x = 35.6 ft

Step-by-step explanation:

B) From definition:

tan(45°) = opposite/adjacent

opposite to angle 45° is x ( the height of the tree), adjacent to angle 45° is the length of the shadow (35.6 ft). Replacing into the equation:

tan(45°) = x/35.6

C) tan(45°) = 1

Then:

1 = x/35.6

35.6 ft = x

#1

As here base is given

We need the height or perpendicular

Answer:

22 hours

Step-by-step explanation:

Ken saves 90% of his earnings.

So, he must earn

270/x =90/100

90x=270*100

90x=27,000

x=27000/90

=300

x=$300 to save $270

For starting 10hours, Ken earns $8 per hour so he earns total

$8*10 hours=$80

Now, Ken has to earn remaining

$220 at a rate of $10/hour, he must work for at least

$220/$10

=22hours

Answer: a) y = f(x - 6)

              b) y = f(x) - 2

Step-by-step explanation:

For transformations we use the following formula: y = a f(x - h) + k

a) f(x) has a vertex at (-1, 1)

    M has a vertex at (5, 1)

    The vertex shifted 6 units to the right  → h = +6

Input h = +6 into the equation and disregard "a" and "k" since those didn't change.     ⇒ y = f(x - 6)

b) f(x) has a vertex at (-1, 1)

    N has a vertex at (-1, -1)

    The vertex shifted down 2 units  → k = -2

Input k = -2 into the equation and disregard "a" and "h" since those didn't change.     ⇒ y = f(x) - 2

Answer:

A = about 2.2 seconds

B = between 0.2 and 1.7 seconds

Step-by-step explanation:

A .to calculate the time in the air, we have to replache h=0.

h = - 16t + 30t +10

0 = - 16t + 30t +10

For: ax2+ bx + c

x =[ -b ± √b²-4ac] /2a

a=-16 ; b=30 ; c=10

Replacing with the values given:

x =[ -30 ± √(30)²-4(-16)10] /2(-16)

x = [ -30 ± √900 +640] /-32

x = [ -30 ± √1,540] /-32

x = [-30 ± 39.24] /-32

Negative:

x = [-30 -39.24] /-32 = 2.16 seconds = about 2.2 seconds

B. .to calculate this, we have to replache h=15.

15 = - 16t + 30t +10

0 = - 16t + 30t +10-15

0=  - 16t + 30t -5

a=-16 ; b=30 ; c=-5

Applying the quadratic formula again:

x =[ -30 ± √(30)²-4(-16)-5] /2(-16)

x = [ -30 ± √900-320] /-32

x = [ -30 ± √580] /-32

x = [-30 ± 24.08] /-32

Positive:

x = [-30 +24.08] /-32 = 0.18 seconds =0.2 seconds

Negative:

x = [-30 -24.08] /-32 = 1.7seconds

Answer:

a) 'X' be the random variable in discrete distribution

b) The value of y = 0.2

c) The mean value or  Expectation value

E (X) = 1.25

d)

The variance σ² of the discrete distribution function is

Variance ( V(x)= 1.2875

Step-by-step explanation:

Step(i):-

Given data

 x    :      0              1        2        3        4

P(x)  :     0.30      0.35      y      0.10   0.05

a)

  Let 'X' be the random variable in discrete distribution

 Given data is discrete distribution

i) If the numbers [tex]p(x_{i} )\geq 0[/tex]  for all values of 'i'

ii) ∑P(x) = 1

Given data [tex]p(x_{i} )\geq 0[/tex]  for all values of 'i'

∑P(x) = 1

0.30+0.35+y+0.10+0.05 =1

                  y + 0.8 = 1

                 y = 1 -0.8 = 0.2

b) The value of y = 0.2

Step(ii):-

Expectation:

Given data

 x    :      0              1          2        3        4

P(x)  :     0.30      0.35      0.2      0.10   0.05

The mean value or  Expectation value

E (x) = ∑ x p ( X = x)

        =  0 × 0.30 + 1 × 0.35 + 2 × 0.2 + 3 × 0.10 + 4 × 0.05

       =     0 + 0.35 + 0.4 + 0.30 + 0.2

      =       1.25

Variance of X

The variance σ² of the discrete distribution function is defined by

                σ²  = ∑ x² p(x=x) - μ²

                     = 0× 0.30 + 1² × 0.35 + 2²× 0.2 +3²× 0.10 + 4²× 0.05 - (1.25)²

                    = 0 + 0.35 + 0.8 + 0.9 + 0.8 - 1.5625

                   = 1.2875

conclusion:-

The mean value or  Expectation value = 1.25

The variance σ² of the discrete distribution function

 V(X) = 1.2875
