Answer: [tex]8x^2-10x-6[/tex]

Step-by-step explanation:

Given : length =  [tex]3x^2-5x+1[/tex] , width = [tex]x^2-4[/tex]

Perimeter of rectangle  = 2 ( length + width)

Then,  Perimeter of given rectangle  = [tex]2 (3x^2-5x+1+x^2-4)[/tex]

[tex]=2 (4x^2-5x-3)\\\\= 8x^2-10x-6[/tex]

Hence, the  correct expression for perimeter = [tex]8x^2-10x-6[/tex]

D. n=35 p =0.7

Step-by-step explanation:

The value of the interval (0.4676, 0.9323) is between (0, 1). Then the correct option is D.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The sample size should be greater than 30.

Then

[tex]\mu = p = 0.7\\\\n = 35[/tex]

Then we have the sigma

[tex]\sigma = \sqrt{\dfrac{p(1-p)}{n}}\\\\\sigma = \sqrt{\dfrac{0.7*0.3}{35}}\\\\\sigma = 0.0775[/tex]

Then we have

[tex](\mu - 3 \sigma , \ \mu + 3 \sigma)\\\\(0.7-0.2323, \ 0.7+0.2323)\\\\(0.4676, \ 0.9323)[/tex]

The value of the interval is between (0, 1). Then the correct option is D.

Answer:

5'506 the answer is 5'506 I because I add 2'500 with 6 and I got that answer

The total amount owed when $2500 is borrowed for one year at 6% simple interest is $2650.

Simple interest is the process of finding the amount of interest if we have some principal value of money. Here a specific interest is charged only for the principal amount.

Formula for calculating the total amount in case of Simple Interest is,

A = p (1 + r t)

where, A is the total amount, p is the principal amount, r is the rate of interest and t is the time period.

Here, p = $2500

r = 6% = 6/100 = 0.06

t = 1 year

So the total amount = 2500 [1 + (0.06 × 1)]

                                 = 2500 [1 + 0.06]

                                 = 2500 × 1.06

                                 = 2650

Hence the total money owed is $2650 when $2500 is borrowed for one year at 6% simple interest.

Answer:

Adult tickets = $8

Children's tickets = $3

Step-by-step explanation:

Set up a system of equations;

x = adult tickets

y = children's tickets

Daryl's situation;

10x + 10y = 110

Rick's situation;

6x + 5y = 63

Hence the system is;

[tex]\left \{ {{10x+10y=110} \atop {6x+5y=63}} \right.[/tex]

To solve by elimination, one has to multiply one of the systems by a number such that when one adds the two systems, one variable gets eliminated. One is then left with an expression that can be solved for the other variable. Finally, one can substitute the value of the other variable back, to find the value of the first variable.

[tex]\left \{ {{10x+10y=110} \atop {6x+5y=63}} \right.[/tex]

Multiply Rick's situation by (-2)

[tex]\left \{ {{10x+10y=110} \atop {-12x-12y= -126}} \right.[/tex]

Add the two equations;

-2x = -16

Inverse operations;

-2x = -16

/-2     /-2

x = 8

Substitute back in;

10x + 1y = 110

10(8) + 10y = 110

Simplify;

80 + 10y = 110

Inverse operations;

80 + 10y =110

-80          -80

10y = 30

/10    /10

y = 3

x = 8

Answer:

B

Step-by-step explanation:

We can determine that it is sin, not cos, because the equation goes through the origin (0, 0).

The amplitude is 2 and since the amplitude is a for an equation in the form of asinx, the equation must have 2sinx.

Finally, the period is pi. The regular period of sinx is 2pi, so inside of the si, x must be multiplied by 2, which gets us to 2sin(2x).

I hope this helps! :)

Step-by-step explanation:

Answer:

0.428x

Step-by-step explanation:

The price of a smart phone is "x" and is discounted 40% for a special promotion.

Step 1

The price after the discount is:

40% of x

= 40x/100

= 0.4x

Step 2

We calculate the exact amount the sales tax is.

You must also pay 7% sales tax on this purchase.

= 7% × 0.4x

= 7/100 × 0.4x

= 0.028x

Step 3

The final price for this purchase is calculated as:

0.4x + 0.028x

= 0.428x

Hence, the final price for this purchase is 0.428x

The image of the inscribed circle is missing so i have attached it.

Answer:

x = 35

None of the given options are correct.

Thus, Option D is the answer.

Step-by-step explanation:

From the attached image, we can see that there are two lines projecting out of the centre of the circle with one having it's endpoint touching the edge of the hexagon while the other is perpendicular to the centre of a side of the hexagon and labeled x has it's endpoint touching both the circumference and the hexagon side.

Since line labeled x projects from the centre of the circle to the circumference, we can say that the radius is x.

The triangle formed is a right angled triangle with the other part touching only the hexagon as the hypotenuse.

We see the remaining part between the circle and the hexagon of this hypotenuse line given as 2.

Thus, hypotenuse = x + 2

This is because from the centre to the circumference is x as earlier discussed and this hypotenuse line crosses the circumference of the circle before touching the edge of the hexagon.

Using pythagoras theorem, we can find x:

x² + 12² = (x + 2)²

x² + 144 = x² + 4x + 4

x² will cancel out to give;

4x + 4 = 144

4x = 144 - 4

4x = 140

x = 140/4

x = 35

Step-by-step explanation:

The minimum value of C is 14 because the inequality x + 3y ≥ 14 has the minimum value is 14.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have:

C = x + 3y

Subject to constraints:

9x + 2y > 35

x + 3y ≥ 14

X ≥ 0

y ≥  0

As we can see in the inequality:

x + 3y ≥ 14

Compare with x + 3y = C

The minimum value of x + 3y is 14

Thus, the minimum value of C is 14 because the inequality x + 3y ≥ 14 has the minimum value is 14.

Solution in photo

Step-by-step explanation:

Answer and Step-by-step explanation:

Let us assume two boys are jogging.

Boy 1 jogging speed is 10 kilometres per hour

Boy 2 jogging speed is 20 kilometres per hour

This can be represented in terms of distance, d and time, t. When we do this, we have:

d = 10t boy 1

d = 20t boy 2

This implies that boy 1 rate of change is 10 kilometers for every one hour and boy 2 is 20 kilometers for every 1 hour.

From here, we can conclude that the rate of change of boy 2 is twice the rate of change of boy 1.
