I Need Help To Find W =

Answers

Answer 1

Answer:

The answer is 12.

Step-by-step explanation:

Since one of the sides on the smaller polygon is two and on the other one is six that must mean the scale is multiply by 3 because 2x3=6. So 4 times 3 is 12.

So, w = 12

Answers

Answer:

[tex]-\frac{5}{2} x^{3} +\frac{17}{8} x^{2} -15[/tex]

Step-by-step explanation:

First combine like terms so for numbers with x^3 you have one:

-[tex]\frac{5}{2} x^{3}[/tex]

Then x^ 2

[tex]\frac{9}{8}x^{2} +x^{2}[/tex]

(4/4x^2 is just x^2 because 4/4 is 1)

So

[tex]\frac{17}{8} x^{2}[/tex]

Then all numbers with x cancel out because

2x+3x-5x is 0.

Then you just have -15.

So put them back together to get what I wrote in the answer.

Solve using the Pythagorean identity

Answers

[tex]\bold{Sin\theta_{1}=-\frac{4}{5}}[/tex]

Answer:

Solution given

Cos[tex]\displaystyle \theta_{1}=\frac{3}{5}[/tex]

consider Pythagorean theorem

[tex]\bold{Sin²\theta+Cos²\theta=1}[/tex]

Subtracting [tex]Cos²\theta[/tex]both side

[tex]\displaystyle Sin²\theta=1-Cos²\theta[/tex]

doing square root on both side we get

[tex]Sin\theta=\sqrt{1-Cos²\theta}[/tex]

Similarly

[tex]Sin\theta_{1}=\sqrt{1-Cos²\theta_{1}}[/tex]

Substituting value of [tex]Cos\theta_{1}[/tex]

we get

[tex]Sin\theta_{1}=\sqrt{1-(\frac{3}{5})²}[/tex]

Solving numerical

[tex]Sin\theta_{1}=\sqrt{1-(\frac{9}{25})}[/tex]

[tex]Sin\theta_{1}=\sqrt{\frac{16}{225}}[/tex]

[tex]Sin\theta_{1}=\frac{\sqrt{2*2*2*2}}{\sqrt{5*5}}[/tex]

Since

In IVquadrant sin angle is negative

[tex]\bold{Sin\theta_{1}=-\frac{4}{5}}[/tex]

Answer:

[tex]\sin(\theta_1)=-\frac{4}{5}[/tex]

Step-by-step explanation:

We'll use the Pythagorean Identity [tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex] to solve this problem.

Subtract [tex]\cos^2(\theta)[/tex] from both sides to isolate [tex]\sin^2(\theta)[/tex]:

[tex]\sin^2(\theta)=1-\cos^2(\theta)[/tex]

Substitute [tex]\cos(\theta)=\frac{3}{5}[/tex] as given in the problem:

[tex]\sin^2(\theta_1)=1-(\frac{3}{5}^2)[/tex]

Simplify:

[tex]\sin^2\theta_1=1-\frac{9}{25}[/tex]

Combine like terms:

[tex]\sin^2\theta_1=\frac{16}{25}[/tex]

For [tex]a^2=b[/tex], we have two solutions [tex]a=\pm \sqrt{b}[/tex]:

[tex]\sin\theta_1=\pm \sqrt{\frac{16}{25}},\\\begin{cases}\sin \theta_1=\frac{4}{5},\\\sin \theta_1=\boxed{-\frac{4}{5}}\end{cases}[/tex]

Since the sine of all angles in quadrant four return a negative output, [tex]\frac{4}{5}[/tex] is extraneous and our answer is [tex]\boxed{\sin(\theta_1)=-\frac{4}{5}}[/tex]

Eight years ago, the daughters age was thrice the son's age. Now the daughter's age is 4 years more than the son's age. Find their present ages.​

Answers

Answer:

Let s be the son’s current age and d be the daughter’s current age. The system of equations is:

s - 10 = 2(d - 10)

s = 3 + d

Since s is already set to an equation, we can use the substitution method for s in the other equation:

s = 3 + d

s - 10 = 2(d - 10)

3 + d - 10 = 2(d - 10)

Simplify and solve for d:

3 + d - 10 = 2(d - 10)

-7 + d = 2d - 20

-7 = d - 20

13 = d

The daughter is 13 years old. To solve for the son’s age, we will plug in the solution for d into one of the equations. The second one is simpler so we will use that:

s = 3 + d

s = 3 + 13

s = 16

The son is 16 years old. Let us use the other equation to check our solutions:

s - 10 = 2(d - 10)

16 - 10 = 2(13 - 10)

6 = 2(3)

6 = 6

It checks out. The son is 16 years old, and the daughter is 13 years old.

The present age of the daughter and son are 14 and 10 years respectively.

Let the age of the daughter be x

Let the age of the son be y

If the daughter's age is 4 years more than the son's age now, then,

x = y + 4 ............. 1

If Eight years ago, the daughters' age was thrice the son's age, then;

Daughter = x - 8

Son  = y - 8

Hence, x - 8 =3(y - 8).................. 2

Substitute equation 1 into 2 to have:

x - 8 =3(y - 8).

y + 4 - 8 = 3(y - 8)

y - 4 = 3y - 24

y - 3y = -20

-2y = -20

y = 10

Recall that x = y + 4

x = 10 + 4

x = 14

Hence the present age of the daughter and son are 14 and 10 years respectively.

Answer:

25%.

Step-by-step explanation:

First, let's find the area of both circles. The area of a circle is given by:

[tex]\displaystyle A = \pi r^2[/tex]

The radius of the smaller circle is one. Thus, its area is:

[tex]\displaystyle A = \pi (1)^2 = \pi[/tex]

The radius of the larger circle is two. Thus, its area is:

[tex]\displaystyle A = pi (2)^2 = 4\pi[/tex]

The probability that a random point chosen will be inside the small circle will be the area of the small circle over the total area. Hence:

[tex]\displaystyle P= \frac{\pi }{4\pi}=\frac{1}{4}= 25\%[/tex]

The probability of a random point being in the small circle is 25%.

Answer:

[tex]x=17[/tex]

Step-by-step explanation:

The two angles labelled [tex]6x+8[/tex] and [tex]4x+2[/tex] are co-interior angles. When two parallel lines are cut by a traversal, co-interior angles are supplementary, meaning they add up to 180 degrees. Therefore, if line L is parallel to line M, [tex]6x+8[/tex] and [tex]4x+2[/tex] must be supplementary:

[tex]6x+8+4x+2=180[/tex]

Combine like terms:

[tex]10x+10=180[/tex]

Subtract 10 from both sides:

[tex]10x=170[/tex]

Divide both sides by 10:

y = + 1/2x -3

Step-by-step explanation:

slope intercept form: y = mx + b

In order to put the given equation in slope intercept form we will need to isolate ( we can do this by solving algebraically ) y as seen in the equation shown above.

x - 2y = 6

Solve for y

Subtract x from both sides

x - x - 2y = 6 - x

-2y = 6 - x

Divide both sides by -2

-2y/-2 = (6 - x)/-2

y = -3 + 1/2x

CINDY BOUGHT A 12.3 POUND TURKEY AND AN 11.7 POUND HAM FOR HOLIDAY DINNER AND PAID $34.68. Her friend Samantha bought a 10.7 pound turkey and 9.5 pound ham for $29.05. What is the cost per pound of turkey and the cot per pound of ham

Answers

Answer:

Cost of Turkey per pound is $ 1.25 and Ham is $ 1.65.  

Step-by-step explanation:

Cindy:

cost of 12.3 pound Turkey and 11.7 pound Ham = $ 34.68

Samantha:

cost of 10.7 pound Turkey and 9.5 pound Ham = $ 29.05

Let the cost of one pound of Turkey is T and one pound of Ham is H.

So,

12.3 T + 11.7 H = 34.68 ..... (1)

10.7 T + 9.5 H = 29.05 ......(2)

Answers

Answer:

Step-by-step explanation:

The given equation of the function is y = -a·(x - h)² + 1

The positive constants of the equation = a, and h

The points the function crosses the x-axis = 2, and 4

Where the function crosses the x-axis, y = 0, and x = 2, and 4, therefore, when x = 2, we have;

y = 0 = -a·(2 - h)² + 1

When x = 4, we have;

0 = -a·(4 - h)² + 1

-a·(2 - h)² + 1 = -a·(4 - h)² + 1

-a·(2 - h)² = -a·(4 - h)²

(2 - h)² = (4 - h)²

±(2 - h) = +#±(4 - h)

When

(2 - h) is negative, and (4 - h) is positive, but the same magnitude, we have';

-(2 - h) = +(4 - h)

2·h = 4 + 2 = 6

h = 3

0 = -a·(4 - h)² + 1 = -a·(4 - 3)² + 1 = -a + 1

Therefore, a = 1

[tex]\int\limits {{(sin \ x})^{-1} } \, dx = \text{ln}\left |{tan\, \left (\dfrac{x}{2} \right)} \right |[/tex]

Step-by-step explanation:

[tex]\int\limits {(sin \ x)^{-1}} \, dx = \int\limits {\dfrac{1}{sin \ x} } \, dx[/tex]

We have the following relationships;

[tex]\dfrac{1}{sin \ x } = csc \, x[/tex]

We can write;

[tex]csc \, x = csc \, x \times \dfrac{csc \, x + cot \, x}{csc \, x + cot \, x} = \dfrac{csc^2 \, x + csc \, x \cdot cot \, x}{csc \, x + cot \, x}[/tex]

We note that the numerator of [tex]\dfrac{csc^2 \, x + csc \, x \cdot cot \, x}{csc \, x + cot \, x}[/tex] , which is [tex]{csc^2 \, x + csc \, x \cdot cot \, x}[/tex] is the derivative of the denominator, [tex]{csc \, x + cot \, x}[/tex], therefore, we can use integration by substitution method and write;

[tex]{csc \, x + cot \, x} = u[/tex], from which we get;

[tex]({csc^2 \, x + csc \, x \cdot cot \, x}) \cdot dx = (-1)du[/tex]

Therefore, we can write;

[tex]\int\limits {\dfrac{1}{sin \ x} } \, dx = \int\limits {\dfrac{{csc^2 \, x + csc \, x \cdot cot \, x}}{{csc \, x + cot \, x}} } \, dx \Rightarrow -\int\limits {\dfrac{1}{u} } \, du = -ln \left |u \right |[/tex]

[tex]\text{-ln} \left |u \right | = \text{-ln}\left |{csc \, x + cot \, x} \right |[/tex]

Therefore;

[tex]\int\limits {\dfrac{1}{sin \ x} } \, dx = \text{-ln}\left |{csc \, x + cot \, x} \right |[/tex]

csc x + cot x = (1/sin x) + ((cos x)/(sin x)) = (1 + cos x)/(sin x)

(1 + cos x)/(sin x) = (cos²(x/2) + sin²(x/2) + cos²(x/2) - sin²(x/2))/(2sin(x/2)·cos(x/2)) = (2·cos²(x/2))/((2sin(x/2)·cos(x/2)) =  cos(x/2)/sin(x/2) = cot(x/2)

Therefore;

[tex]\text{-ln}\left |{csc \, x + cot \, x} \right | = \text{-ln}\left |{cot \, \left (\dfrac{x}{2} \right) } \right | = \text{ln}\left |{cot \, \left (\dfrac{x}{2} \right)} \right | ^{-1} = \text{ln}\left |{tan\, \left (\dfrac{x}{2} \right)} \right |[/tex]

Therefore;

[tex]\int\limits {{(sin \ x})^{-1} } \, dx = \int\limits {\dfrac{1}{sin \ x} } \, dx = \text{ln}\left |{tan\, \left (\dfrac{x}{2} \right)} \right |[/tex]
