What is the integral of (x + 1)(3x + 2) from -1 to 1?

Answer:

19cm

Step-by-step explanation:

An equilateral triangle is a triangle where the length of the 3 sides are the same.

the perimeter is the sum of the 3 sides

for example, if the length of the side of the an equilateral triangle is 5, the perimeter is 5 x 3 = 15

let x = unknown length of side

length after increase = x + 5

(x + 5) x 3 = 72

divide both sides of the equation by 3

x + 5 = 24

subtract 5 from both sides of the equation

x = 24 - 5 = 19cm

Answer:

Step-by-step explanation:

7. The horizontal translation is 3 units to the right, this is determined by the value that is being added or subtracted to x directly. In this case, x is being subtracted by 3 meaning that it is translated 3 units to the right.

8. It is being translated 2 units up. This is determined by the number that is added to the quadratic equation. In this case, it is increased by 2 which means an upward translation. If it was being subtracted it would be a downward translation.

9. Yes, when a quadratic equation has a negative sign outside of it which changes its values it means that it is being reflected.

A study with a sample that is very different from the population is biased

The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.

Population density = number of people / the area they occupy

Given data ,

A study with a sample that is very different from the population is J. biased.

In statistical terms, bias refers to any systematic error or deviation from the true value that can occur in a study. When a study is biased, the results may not be representative of the population and may not be generalized other settings.

Results from a research may be skewed if the sample chosen is considerably different from the population. Both experimental and observational research may experience this. As a result, alternatives F and G do not offer sufficient details to assess the study's objectivity.

Answer:

Area of a circle = 200.96 yd²

Step-by-step explanation:

Area of a circle = πr²

Radius, r = 8 yd

π = 3.14

Area of a circle = πr²

= 3.14 * (8 yd)²

= 3.14 * 64

= 200.96 yd²

Area of a circle = 200.96 yd²

Answer:

254

Step-by-step explanation:

This is basically a triangle, with a height of 2, and hypotenuse of 16.

Using the Pythagorean theorem (a^2+b^2=h^2) we can find the other side.

2^2+b^2=16^2

4+b^2=256

b^2=254

b=√254

Answer:

1. x= 9

2. x= −2

3. 51 inches

4. $213.11 each month

Step-by-step explanation:

1. Simplify both sides of the equation.

x + 7 + 7x= 25 + 6x

Combine Like Terms

(x + 7x) + (7)=6x + 25

8x + 7= 6x + 25

8x + 7= 6x + 25

Subtract 6x from both sides.

8x + 7 − 6x= 6x + 25 − 6x

2x + 7= 25

Subtract 7 from both sides.

2x + 7 − 7= 25 − 7

2x= 18

Divide both sides by 2.

2x/2= 18/2

2.  Subtract 5x from both sides.

x − 5x= 5x + 8 − 5x

−4x= 8

Divide both sides by -4.

−4x/−4= 8/−4

3. First find the perimeter of the trapezoid

4 + 3 + 4 + 8= 19

A square has all equal sides

8 * 4= 32

Add them together

19 + 32 = 51 inches

4. Subtract the amount she put for finance from the total

Answer:

88

Step-by-step explanation:

Each triangle has a sum of 180 degrees. So we find the missing angle with this rule.

180-38-50.

The angle is 92 degrees.

Now to find the angle of A, each angle adds up to 180 on a line. so 180-92. So you get 88

Answer:

Step-by-step explanation:

38+50=angle A(the sum of two interior opposite angle is equal to the external angle formed)

Step-by-step explanation:

½×(210+84)×318

= 46,746 mm²

( 2x − 27 ) ( −x + 15 )

= ( 2x + −27 ) ( −x + 15 )

= ( 2x ) ( −x ) + ( 2x ) ( 15 ) + ( −27 ) ( −x ) + ( −27 ) ( 15 )

= −2x^2 + 30x + 27x − 405

The probability of  the percentage of thefts in a random sample of 400 would be greater than or equal to 3 is  given by  P (z> 1.09)   = 0.1379

Step-by-step explanation:

The statistic

z= p^- p / √pq/n

is used to measure the difference between the sample and population proportions.

Here p^= 12/400= 0.03

p= 0.022               q= 1-0.022=0.978

 and n=400

Putting the values

Z= 0.03-0.022/√0.022(1-0.022)/400

Z= 0.008/√0.022(0.978)/400

Z= 0.008/0.00733

z= 1.090

We have to find the probability of  the percentage of thefts in a random sample of 400 would be greater than or equal to 3

or

Mathematically

P (z> 1.09)= 1- P (z≤1.09)

                  = 1- 0.8621   ( from the z area table)

                   = 0.1379
