find the area of the figure

Answer:

B

Step-by-step explanation:

The association property of multiplication states that if we have three numbers such as:

\(a\cdot b\cdot c\)

Then the order of parentheses will not matter. In other words:

\((a\cdot b)\cdot c=a\cdot (b\cdot c)\)

For instance:

\((3\cdot4)\cdot5=3\cdot(4\cdot5)\)

For the choices, it must have at least three terms. Thus, eliminate A.

It must also have parentheses. Eliminate D.

Choice C represents the distributive property, where you distribute a factor into the expression.

Thus, the correct answer is choice B.

And as previously mentioned, the order of the parentheses does not make the product any different.

\(6*(9*1)=6*(9)=54\\(6*9)*1=(54)*1=54\)

Answer:

The correct answer choice is B.

Step-by-step explanation:

The digits should still be in order, so A is incorrect. 6 * 91 does not even equal 69 * 1!

B shows that be can multiply 6 * 9 * 1 in any order. This means we can place a pair of parentheses around any of these numbers and the answer will still be the same.

C is incorrect. We want an equation that helps give us a better understanding of MULTIPLICATION, not ADDITION. The equation is also false.

Finally, D illustrates the commutative property of multiplication- you can multiply your numbers in any order and it will still have the same value. Put simply, it's incorrect.

Let me know if you need more elaboration!

Answer:

Multiply (1) by 5.

5x+20y=15

-5x-20y=-15.

Add

0=0.

Infinetly many solutions.

I know this is correct because if i do -(-5x-20y=-15)

it will be 5x+20y=15 which is the same as (1)

5r + 10 = 65

5r =65 - 10

r = 55/5

r = 11

Answer:

r=11

Step-by-step explanation:

you first have to work with the brackets and then group the like terms

5(r+2)=8+57

5r+10=65

5r/5=65-10

5r/5=55/5

To increase real GDP and bring it closer to potential GDP during a recession, the government could increase government spending and/or decrease taxes.

During a recession, when real GDP is below potential GDP, the government can use fiscal policy tools to stimulate economic growth and close the GDP gap. The two options that can be effective in this situation are increasing government spending and decreasing taxes.

Increase government spending: By increasing spending on infrastructure projects, education, healthcare, or other sectors, the government can create demand in the economy, which leads to increased production and employment, ultimately raising real GDP.

Decrease taxes: Reducing taxes can provide individuals and businesses with more disposable income, encouraging consumption and investment. This increased spending and investment can boost aggregate demand, leading to higher production levels and closing the GDP gap.

Decreasing government spending and increasing taxes, on the other hand, would have contractionary effects, potentially exacerbating the recessionary conditions by reducing overall demand in the economy. Therefore, these options are not suitable for increasing real GDP during a recession.

2. The slope of the line is 4/3. Option-1 is correct.

Given that,

There are 2 pictures.

In the first picture we have to find which table satisfy the equation.

In the second picture we have to find slope of the given graph.

First,

The given equation is y=-3x+2

In every option the x values are same that is -1,0,1,2.

Substitute x value as -1,0,1,2

Taking x as-1

y=-3(-1)+2

y=3+2

y=5

Taking x as 0

y=-3(0)+2

y=2

Taking x as 1

y=-3(1)+2

y=-3+2

y=-1

Taking x as 2

y=-3(2)+2

y=-6+2

y=-4

Therefore, we got (x,y)=(-1,5),(0,2),(1,-1),(2,-4). Option -3 is correct.

Now, We see the second picture.

Given line point are (2,2) and (-1,-2)

Slope of the line formula is \(\frac{y_{2} -y_{1} }{x_{2} -x_{1} }\)

Slope =(-2-2)/(-1-2)

Slope=-4/-3

Slope=4/3

Therefore, the slope of the line is 4/3. Option-1 is correct.

The canonical expression equivalent to sinusoidal model y(t) = 2 · sin (4π · t) + 5 · cos (4π · t) is y(t) = (√ 29) · sin (4π · t + 0.379π) .

Herein we have a simple harmonic motion model represented by a sinusoidal expression of the form y(t) = A · sin (C · t) + B · cos (C · t), which must be transformed into its canonical form, that is, y(t) = A' · sin (C · t + D). We proceed to perform the procedure by algebraic and trigonometric handling.

The amplitude of the canonical function is determined by the Pythagorean theorem:

A' = √(2² + 5²)

A' = √ 29

The angular frequency C  is the constant within the trigonometric functions from the non-canonical formula:

C = 4π

Then, we find the initial position of the weight in time: (t = 0)

y(0) = 2 · sin (4π · 0) + 5 · cos (4π · 0)

y(0) = 5

And now we calculate the angular phase below: (A' = √ 29, C = 4π, y = 5)

5 = √ 29 · sin (4π · 0 + D)

5 / √ 29 = sin D

D ≈ 0.379π rad

The canonical expression equivalent to sinusoidal model y(t) = 2 · sin (4π · t) + 5 · cos (4π · t) is y(t) = (√ 29) · sin (4π · t + 0.379π) .

We can solve the triangle using the law of sines and law of cosines. To use the law of sines, we know that sin β/ b = sin γ/ c and

sin α/ a = sin γ/ c where α, β, and γ are the angles in the triangle.

We have two equations, so we can solve for b and γ: sin β/ b = sin γ/ c

=> sin 21°/ b = sin γ/10

=> sin γ = 10sin 21° / b.

sin α/ a = sin γ/ c

=> sin α/7 = sin γ/10

=> sin γ = 10sin α/7.

Therefore, 10sin 21° / b = 10sin α/7, and we can solve for α:

sin α = 7sin 21°/b

=> α = sin-1(7sin 21°/b).

We can then use the fact that the sum of angles in a triangle is 180° to solve for γ: γ = 180° - α - β.

To use the law of cosines, we know that a² = b² + c² - 2bc cos α.

We have a, c, and α, so we can solve for b: b² = a² + c² - 2ac cos β.

We have a, b, and c, so we can solve for the perimeter, P = a + b + c, and the semiperimeter, s = P/2.

Once we have the perimeter, we can use Heron's formula to find the area: A = sqrt(s(s - a)(s - b)(s - c)).

The approximate values of a, b, and γ, rounded to one decimal place, are:a ≈ 7.6b ≈ 4.2γ ≈ 138.0°

The area is approximately A ≈ 24.2.

Answer:

400

Step-by-step explanation:

Therefore, there are 210 different combinations of sequences that have 4 heads and 6 tails in 10 coin flips.

If heads come up four out of ten times that you flip a coin, this means that we have 4 heads and 6 tails in the sequence of 10 coin flips. The order of the heads and tails is important, so we are counting the number of possible sequences.

To calculate the number of possible sequences, we can use the formula for combinations:

C(n, r) = n! / (r! * (n - r)!)

here n is the total number of items (in this case, 10 coin flips), and r is the number of items we want to choose (in this case, the 4 heads).

So the number of different combinations of sequences with 4 heads and 6 tails is:

C(10, 4) = 10! / (4! * (10 - 4)!) = 210

To produce 200 watts of power, the speed of wind must be about 11 miles per hour for the windmill.

The relationship between power generated by a windmill and wind speed can be expressed as:

P = k * V^3

where P is the power generated in watts, V is the wind speed in miles per hour, and k is the variation constant.

We are given that k = 0.15, and we need to find the wind speed V that produces 200 watts of power. We can solve for V as follows:

200 = 0.15 * V^3

V^3 = 200 / 0.15

V^3 = 1333.33

V = (1333.33)^(1/3)

V ≈ 10.68

Rounding to the nearest mile per hour gives a wind speed of 11 miles per hour. Therefore, the wind needs to be blowing at about 11 miles per hour for the windmill to produce 200 watts of power.

(i) Revised: There is a strong association between cigarette smoking and gender.

Explanation: In this context, correlation is not the correct term because correlation measures the linear relationship between two quantitative variables. Instead, we can use the term "association" which is a more general term and can be used with categorical variables such as gender and smoking habits.

(ii) Revised: The correlation between age and weight of a newborn baby is r=0.83.

Explanation: Correlation, denoted by 'r', is a unitless measure that describes the strength and direction of a linear relationship between two quantitative variables. The units (in this case, 'ounces per day') are not applicable to the correlation coefficient.

(iii) The statement is correctly stated.

(iv) Revised: The correlation between a person's age and vision (assuming vision measured as a quantitative variable) is r = -1.

Explanation: The correlation coefficient (r) must lie between -1 and 1 inclusive. Hence, a correlation coefficient of -1.04 is not possible. If the correlation is -1, it indicates a perfect negative linear relationship between a person's age and their vision.
