Answer 1

Let's see

Area=Length×Breadth(2x+1)(x-7)=172x(x-7)+1(x-7)=172x²-14x+x-7=172x²-13x-24=0

On solving

x=8

So

length

2(8)+1=17

Width

8-7=1
Answer 2
✭ Question -:

A rectangle has a length of (2x+1) units, a width of (x-7) units and an Area of 17 square units. Find the dimensions of the rectangle.

✭ Explanation -:

In this question we are provided with the length of a rectangle (2x + 1) units and the width of the rectangle (x - 7). It is also given that the area is 17 units². We are asked to calculate the length and width of the rectangle.

First we will find the value of x

We know,

[tex] \bull \: \small\boxed{ \rm{ Area_{(rectangle)} = Length × Width}}[/tex]

Substituting the values we get

[tex] \small\sf{ (2x + 1 ) (x - 7) = 17}[/tex]

[tex] \small\rm{ 2x( x - 7) + 1(x - 7) = 17}[/tex]

[tex] \small\rm{ 2 {x}^{2} - 14x + 1(x - 7) = 17}[/tex]

[tex] \small\rm{ 2 {x}^{2} - 13x - 7 = 17}[/tex]

[tex] \small\rm{2 {x}^{2} - 13x - 7 - 17 = 0 } [/tex]

[tex] \small\rm{2 {x}^{2} - 13x - 24 = 0} [/tex]

[tex] \small\rm{x = \dfrac{13 + 19}{2 \times 2} } [/tex]

[tex] \small\rm{ x = \dfrac{32}{4} = 8}[/tex]

[tex] \small\sf{x = 8} [/tex]

Now we will substitute the value of x

Length = (2x + 1) = 2 × 8 + 1 = 16 + 1 = 17 units

Width = (x - 7) = 8 - 7 = 1 units

Hence, the length of the rectangle is 17 units and the width is 1 units.

Answers

Answer:

a = 12

Step-by-step explanation:

Pythagoras’ Theorem

a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

From inspection of the triangle:

leg a = aleg b = 9hypotenuse c = 15

Substituting these values into the formula and solving for b:

⇒ a² + 9² = 15²

⇒ a² + 81 = 225

Subtract 81 from both sides:

⇒ a² + 81 - 81 = 225 - 81

⇒ a² = 144

Square root both sides:

⇒ √(a²) = √(144)

a = 12

PLS PLS HELP ME

Answers

The mean absolute deviation for the Jumping Jackrabbits was of 3.8, which was lower than the 6.8 for the Leaping Lizards, hence they had more consistent scores.

What is the mean absolute deviation of a data-set?

The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation(MAD) of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean.

For the Jumping Jackrabbits and the Leaping Lizards, the mean and the MAD are given as follows:

M = (70 + 65 + 72 + 80 + 73)/5 = 72

MAD = (|70 - 72| + |65 - 72| + |72 - 72| + |80 - 72| + |73 - 72|)/5 = 3.6.

M = (61 + 47 + 70 + 63 + 54)/5 = 59

MAD = (|61 - 59| + |47 - 59| + |70 - 59| + |63 - 59| + |54 - 59|)/5 = 6.8.

The mean absolute deviation for the Jumping Jackrabbits was of 3.8, which was lower than the 6.8 for the Leaping Lizards, hence they had more consistent scores.

Step-by-step explanation:

Parallel lines and transversal:

 Linear pair: When the uncommon arms of two adjacent angles form a straight line, the adjacent angles are called linear pair and they add upto 180

3)  ∠3 + ∠2 = 180

     65 + ∠2 = 180

             ∠2 = 180 - 65

            ∠2 = 115°

When parallel lines   are intersected by  transversal, alternate exterior angles are congruent.

a // b and d is transversal.

  ∠5 = ∠11

 ∠5 = 100°

When  parallel lines are intersected by transversal, the alternate interior angles are congruent.

a // b and c is transversal

m∠13 = ∠3

  ∠13 = 65°

4)    ∠3 &  ∠14 are co-interior angles. Co-interior angles are supplementary.

∠3 +  ∠14 = 180

65 +  ∠14  = 180

           ∠14 = 180 - 65

           ∠14 = 115°  

∠5 +  ∠8 = 180    {Linear pair}

 100 +  ∠8 = 180

             ∠8 = 180 - 100

             ∠8= 80

∠9 =  ∠11 {vertically opposite angles are congruent}

∠9 = 100

∠ 3 + ∠14 + ∠ 8 + ∠9 = 65 + 115 + 80 + 100

                                   = 360°

write the above equation in the form of y = g(x).

⇒ y = (0.5)x + 3 – 4

Now, we convert the equation into y = mx + c form.

⇒ y = (0.5)x - 1

Here, we see that m = slope = 0.5, and c = y-intercept = -1.


Hence, the graph of g(x) = (0.5)x + 3 – 4 is a straight line with slope = 1/2 and y-intercept = -1.

Step-by-step explanation:

Solve the entire figure first

First right triangle:

A = 36

B = 48

C = _

Using Pythagoras theorem to find the hypotenuse

a² + b² = c²

Plug in:

36² + 48² = 84²

1,296 + 2,304 = 3,600

Find the square root of √3600

⇒ √3600 = √( 2 × 2) × (2 × 2) × (3 × 3) × (5 × 5)

⇒ = 2 × 2 × 3 × 5

⇒ 60

The hypotenuse of the bottom right triangle is 60.

Now that we have the given value of the missing line separating both right triangles.

A = 60

C (hypotenuse) = 75

To find the missing side,

use this formula:
c² - a² = b²   ---> hypotenuse minus the given side value

Plug in:

75² - 60² = 2,025

Find the square root:

⇒ √2025 = √ ( 3 × 3 ) × ( 3 × 3 ) × ( 5 × 5 )

⇒ 3 × 3 × 5

⇒ 45

Therefore, the missing x value on the second right triangle is 45.

give two coterminal angles (one positive and one negative) and the reference angle. 290

Answers

The coterminal  angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.

What is coterminal angles?

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle:

290 degree

To find the coterminal angle, add and subtract 360 degree in the angle 290 degree.

Coterminal angle = 290 + 360 = 650 degree

                               = 290 - 360 = -70 degree

Reference angle = 360 - 290 = 70 degree

Thus, the coterminal  angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.

The next two terms are -32 and 64.

                First of all, let's identify what kind of sequence this is.

The two main types of sequences are:

[tex]\textsf{Arithmetic.}[/tex] This is where we add/subtract the same number to get to the following term.[tex]\textsf{Geometric.}[/tex] This is where we multiply/divide by the same number to get to the next term.

In the given sequence, we use multiplication, so we're dealing with a [tex]\textit{geometric sequence}[/tex].

In order to get to the next term, we multiply by -2.

So in order to find the next two terms of the sequence, we take the previous term and multiply it by -2 as follows:

16•(-2)=-32

We've found the 5th term of the geometic sequence.

Now let's find the 6th:

-32•(-2)=64 (the product of a negative and a negative results in a positive)

Summary of Final Answer:-

The next two terms in the sequence are -32 and 64.

Good luck.
