Answer:

150°

Step-by-step explanation:

Both the measure of <1 and <2 are 150°

Solving a linear equation we will see that there are 47 worms in the container

We know that the mass of the container is 225 grams, and the mass of each worm is 11.2 grams.

Then if there are x worms on the containers, the total mass is:

M(x) = 225g + x*11.2g

In this case, we know that the total mass is 751.4 grams, then we can write:

751.4 g = 225g + x*11.2g

Solving this linear equation we get:

751.4g - 225g = x*11.2g

526.4g = x*11.2g

526.4g/11.2g = x = 47

The sketch of the given parametric equations is as appended.

Given parametric equations,

x(t) = 1+2t

y(t) = [tex]t^{2}[/tex]

y = [tex]\frac{(x-1)^{2}}{4}[/tex]

For bounding range of -2 ≤ t ≤ 2, corresponding values of x are as follows,

x = 2t + 1

For t = -2, x = 2(-2) + 1 = -3

For t = 2, x = 2(2) + 1 = 5

Hence the graph has been drawn with bounding limits of -3 ≤ x ≤ 5

The outcome is a parabola with vertex at (1,0) and open upwards. The curve moves towards infinity in upwards direction if there are no bounds / range.

The linear function passing through the point (2,-9) that is perpendicular to the line y=x+6 is:

y = -x -7.

A linear function is modeled according to the following rule:

y = mx + b.

The coefficients of the linear function are as follows:

When two lines are perpendicular, the multiplication of their slopes is of -1.

For this problem, the line is perpendicular to line y = x + 6, which has slope 1, hence:

m = -1.

Then:

y = -x + b.

When x = 2, y = -9, hence we use this to find the intercept b as follows:

-9 = -2 + b

b = -7.

Hence the rule is:

y = -x -7.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

To solve this equation, use the distributive property. Isolate the difference between the numbers from one side of the equation.

Distributive property:

A(B+C)=AB+AC

-1.9 = 0.5(p +1.7)

First, switch sides.

0.5(p+1.7)=-1.9

Divide by 0.5 from both sides.

[tex]\sf{\dfrac{0.5\left(p+1.7\right)}{0.5}=\dfrac{-1.9}{0.5}}[/tex]

Solve.

-1.9/0.5=-3.8

p+1.7=-3.8

Then, you subtract by 1.7 from both sides.

p+1.7-1.7=-3.8-1.7

Solve.

Add or subtract the numbers from left to right.

-3.8-1.7=-5.5

[tex]\rightarrow \boxed{\sf{p=-5.5}}[/tex]

Therefore, the correct answer is p=-5.5.

I hope this helps, let me know if you have any questions.

The value of p on the equation - 1.9 = 0.5(p +1.7) is - 5.5.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, we have to solve for p in the equation - 1.9 = 0.5(p +1.7).

0.5(p + 1.7) = - 1.9

First, we'll distribute the terms.

0.5p + 0.85 = - 1.9.

0.5p = - 1.9 - 0.85.

0.5p = - 2.75.

p = - 2.75/0.5.

p = - 5.5

The Zeros of the polynomial function partially graphed below have even multiplicity are x = -3 and x = 3.

The zeros of a Polynomial graph are simply the points where the graph curve crosses the x-axis.

In simply terms, the Zeros of a function are the values of the independent variable that make the function equal to 0. Multiplicity just refers to how many copies of a given zero exist.

From the given graph, the zeros of the Polynomial function are x = 2 and x = 3 and x = -3

An odd multiplicity means the graph of the function crosses the x-axis at that point. An even multiplicity means the curve contacts the x-axis at that point and backs instead of crossing.

b. This type of reason is useful because functions in an equation can take input from many variables, but always give the same result, which is unique to that function.

The connection between the input or domain and the output or range is called a function rule. When there is exactly one value in the range for each domain value, a relation is a function.

f(x), where x is the input value, is how functions are expressed.

All functions have the general form y = f(x)

The simplified equation is sin(2x) = 2

The trigonometry ratio is given as

2sinxcosx/sin^2x+cos^2x-1= 1

Rewrite the equation of the trigonometry formula properly

So, we have the following equation

2sin(x)cos(x)/sin^2(x)+cos^2(x) -1 = 1

Add 1 to both sides of the equation

So, we have the following equation

2sin(x)cos(x)/sin^2(x)+cos^2(x) = 2

Express 2sin(x)cos(x) as sin(2x)

So, we have the following equation

sin(2x)/sin^2(x)+cos^2(x) = 2

Express sin^2(x)+cos^2(x) as 1

So, we have the following equation

sin(2x)/1 = 2

Answer:

1. 0.30

2.4 over 20

3. x is greater than 1.5

4. 19.2

5. 468.11

Step-by-step explanation:

1) 1.4m = 0.42.

Divide both sides by 1.4

1.4m/1.4 = 0.42/1.4

m = 0.30

2) 13/20=j+9/20

Flip equation

j + 9/20 = 13/20

Substract 9/20 from both sides

j + 9/20 - 9/20 = 13/20 - 9/20

j = 13 - 9/20

j = 4/20

3) x − 1.3 = 1.5?

Add 1.3 to both sides

x - 1.3 + 1.3 = 1.5 + 1.3

x = 2.8

So, x is greater than 1.5

4) x/6 + 0.4 =3 + 0.6

Substract 0.4 from both sides

x/6 + 0.4 - 0.4 = 3 + 0.6 -0.4

x/6 = 3 + 0.2

x/6 = 3.2

Multiply both sides by 6

x/6 • 6 = 3.2 • 6

x = 19.2

5) k − 173.54 = 294.57.

Add 173.54 to both sides

k - 173.54 + 173.54 = 294.57 + 173.54

k = 468.11

The value of m from the given equation is 0.3.

The given equation is 1.4m = 0.42.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1) 1.4m = 0.42

⇒ m = 0.42/1.4

⇒ m = 0.3

2) 13/20 = j+9/20

⇒ j = 13/20 - 9/20

⇒ j = 4/20

⇒ j = 1/5

3) x - 1.3 = 1.5

⇒ x = 1.5 + 1.3

⇒ x = 2.8

4) x/6 + 4/10 = 3 + 6/10

⇒ x/6+0.4=3.6

⇒ x/6 = 3.2

⇒ x = 19.2

5) k − 173.54 = 294.57

⇒ k = 294.57+173.54

⇒ k = 468.11

Answer

Largest Area that can be enclosed = 361250 m²

Explanation

Let the length of the fencing along the river be L

Let the width of the fencing be W

A sketch of the problem will make it clearer

Perimeter = L + 2W

Perimeter is giving as the total length of the fencing to be 1700 m

L + 2W = 1700

L = 1700 - 2W

The area of the structure is given as

Area = LW

The area is what we want to maximize

Recall, L = 1700 - 2W

Area = LW = (1700 - 2W) × W = 1700W - 2W²

A = 1700W - 2W²

At maximum point, the derivative of any function is zero

Hence,

(dA/dW) = 1700 - 4W

At maximum point,

(dA/dW) = 0

1700 - 4W = 0

4W = 1700

Divide both sides by 4

(4W/4) = (1700/4)

W = 425 m

Recall, L = 1700 - 2W

L == 1700 - 2(425)

L = 1700 - 850

L = 850 m

Maximum Area

= (Length at maximum area) × (Width at maximum area)

= 850 × 425

= 361250 m²
