the equation sin(40)=b/20can be used to determine the length of segment ac . what is the length of ac? round to the nearest tenth

Answers

If the equation [tex]sin(40)=\frac{b}{20}[/tex] can be used to determine the length of segment AC, then the length of AC is 12.85 units

Given,

The equation,

sin 40 = [tex]\frac{b}{20}[/tex]

We know,

According to trigonometric equation

sin θ= Opposite side / Hypotenuse.

Length of the segment AC = b

Then,

sin 40 = [tex]\frac{b}{20}[/tex]

b= sin 40 × 20

b= 12.85 units

Hence, if the equation [tex]sin(40)=\frac{b}{20}[/tex] can be used to determine the length of segment AC, then the length of AC is 12.85 units

The equation of the function is

Answers

Answer:

y = -8

Step-by-step explanation:

line x = 8 is a vertical line so the line perpendicular has slope of 0

Using m = 0, x = -9, y = -8

y = mx + b

-8 = 0(-9) + b

b = -8

so y = -8

2x+p/q=2x+q/p, p DOESNt equal to 0, q doesn’t equal to 0

Answer: If p=q, ______. If p doesn’t equal q, _______.

Answers

The equation, [tex] \frac{2 \cdot x + p}{q} = \frac{2 \cdot x + q}{p} [/tex], gives;

When p = q, the number of solutions is infinite.

When p ≠ q, the equation has no solution

How can the given equation be evaluated?

The given equation is presented as follows;

[tex] \frac{2 \cdot x + p}{q} = \frac{2 \cdot x + q}{p} [/tex]

If p = q, we have;

[tex] \frac{2 \cdot x + q}{q} = \frac{2 \cdot x + q}{q} [/tex]

[tex] \frac{2 \cdot x + p}{p} = \frac{2 \cdot x + p}{p} [/tex]

Therefore, the equation has an infinite number of solutions when p = Q

If p ≠ q, and x = 3, we have;

[tex] \frac{2 \cdot x + p}{q} = \frac{2 \times 3 + p}{q} = \frac{6 + p}{q} [/tex]

[tex] \frac{2 \cdot x + q}{p} = \frac{6 + q}{p} [/tex]

[tex] \frac{6 + p}{q} [/tex] = \frac{6 + q}{p} [/tex]

6•p + p² = 6•q + q²

However;

p ≠ q

Therefore;

6•p ≠ 6•q

p² ≠ q²

6•p + p² ≠ 6•q + q²

Which gives;

[tex] \frac{6 + p}{q} \neq \frac{6 + q}{p} [/tex]

The equation is not defined when p ≠ q

what is the direction of vector v if it ends at (-3,-10)

Answers

The direction of the vector v in standard position is approximately 253.301°.

What is the direction of a given vector?

Vectors in rectangular form present the change of each of the two variables parallel to orthogonal axes. Each point is described by the following definition:

v = (Δx, Δy)                         (1)

And the direction of a vector is equal to this inverse trigonometric function:

θ = tan⁻¹ (Δy / Δx)              (2)

If we know that Δx = - 3 and Δy = - 10, then the direction of the vector is:

θ = tan⁻¹ (- 10 / - 3)

θ = tan⁻¹ (10 / 3)

θ ≈ 253.301°

Pablo received a gift card of $100 for a pizza restaurant .The restaurant charges $15 per pizza. Teresa received a gift card of $70 for a different pizza restaurant .the restaurant charges $10 per pizza .let X be the number of pizzas purchase. for each card write an expression for the amount of money left on the card after purchasing X pizzas.

Answers

a)Amount of money left on Pablo's card in dollars = $100 - $15x

= $(90 - 15x)

b) Amount of money left on Teresa's card in dollars= $70 - $10x

= $(70 - 10x)

c) Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.

$100 - 15x = $70 - 10x

Let x be the number of pizzas purchased. For each card, write an expression for the amount of money left on the card after purchasing x pizzas.

For Pablo

Keith received a gift card of $100 for a pizza restaurant. The restaurant charges $15 per pizza.

x numbers of pizza costs = $15x

Hence, the amount of money left on Pablo's card after purchasing x pizzas = $100 - $15x

For Teresa,

Mary received a gift card of $70 for a different pizza restaurant. The restaurant charges $10 per pizza.

Hence, x number of pizzas cost =$10 × x

= $10x

Therefore, the amount of money left on Mary's card after she buys x pizzas =

$70 - $10x

Amount of money left on Pablo's card in dollars = __________

Amount of money left on Teresa's card in dollars=____________

Write an equation to show that the two cards have the same amount of money left on them.

To find the equation that shows that the two cards have the same amount of money =

Equation 1 = Equation 2

$100 - 15x = $70 - 10x

Collect like terms

-15x + 10x = $70 - $100

-5x = -30

x = 30/5

x = 6

Hence, anytime Pablo and Teresa buys ,6 pizzas their gift card will have the same amount of money left on them.

A rectangular room is 15 ft long and 10 ft wide. A scale drawing of the room had a width of 5 inches.What is the length of the room in the drawing?​

Answers

Answer:

7.5 inches

Step-by-step explanation:

15 ft long and 10 ft wide becomes 3/2 when converted into a ratio

we now have 3/2 and five inches

3 is 1.5*2

5*1.5 is 7.5

Answer:

7.5in

Step-by-step explanation:

If the original room's dimensions are (15ft x 10ft). Then the new scaled-down version is (?ft x 5in) we can set up a ratio of 10/5 = 2 to find that the scale from the room to the drawing is being shrunk by a factor of 2. So if you take 15/2 you will get your final answer of the new length of 7.5in!

Eighty meters of fencing is available to enclose the rectangular garden of Mang
Gustin. Give a function A that can represent the area that can be enclosed in
terms of x.

Answers

A function that can represent the area that can be enclosed in terms of x is 40x-x².

Given that Eighty meters of fencing is available to enclose the rectangular garden of Mang Gustin.

Area is defined as the amount of space that can be used within a flat surface or the surface of a solid. Perimeter is defined as a continuous line that forms a boundary to define a two-dimensional shape.

Let the length of garden, l=x

and the given perimeter, p=80

As we know, perimeter of rectangle is P=2(l+b).

Now, we will substitute the values and find the value of b, we get

80=2(x+b)

Now, we will divide both sides by 2, we get

80/2=2(x+b)/2

40=x+b

Further, subtract x from both sides, we get

40-x=x+b-x

40-x=b

Now, we will find the area of rectangle by using the formula A=lb.

Substitute the values in above formula, we get

A=x(40-x)

A=40x-x²

Hence, the area that can be enclosed in terms of x is 40x-x².

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

The equation is

13x + y = 26

We have to find the value of x and y .
