which equation describes the line which passes through the points (0. 17, 0) and (0, 0.51)

Answer:

(10,8)

Step-by-step explanation:

The equation of a circle has the following form:

[tex](x-h)^2+(y-k)^2=r^2[/tex] where (h,k) is the center of a circle with radius r.

Our equation is:

[tex](x-10)^2+(y-8)^2=256[/tex]

The center is (10,8).

The center of the circle given by the equation (x−10)² + (y−8)² = 256 is (10, 8). This can be derived from the standard form of a circle's equation. Therefore, the coordinates are (10, 8).

The given equation of the circle is (x−10)² + (y−8)² = 256.

This equation is in the standard form of a circle's equation, (x−h)² + (y−k)² = r², where (h, k) represents the center and r is the radius.

In this case, the values of h and k can be directly identified from the equation: h = 10 and k = 8.

Therefore, the center of the circle is at the coordinates (10, 8).

Answer:

The answer is C.  ASA

Step-by-step explanation:

The SAS doesn't work here, and there are not two angles right next to each other to use.

Answer: D) not possible

SAS won't work because the angles marked are not between the side lengths with the tickmarks

AAS won't work because we only have one pair of angles, not two. ASA is a similar story.

So that leaves "not possible" as the only answer. We simply don't have enough info. The triangles could be congruent, or they may not be. We simply don't know.

Answer:

62.8 in

Step-by-step explanation:

Circumfrence=pi x diameter

3.14 x 20=62.8

Final answer:

Given π as approximately 3.14159, the circumference is found to be about 62.8318 inches.

Explanation:

The question asks for the circumference of a circle with a diameter of 20 inches. To find the circumference (C), we use the formula C = πd, where π (Pi) is approximately 3.14159, and d is the diameter of the circle. Given the diameter (d) of 20 inches, the circumference is calculated as follows: C = 3.14159 × 20.

Substituting the values into the equation provides: C = 62.8318 inches. Hence, the circumference of the circle with a diameter of 20 inches is approximately 62.8318 inches.

Answer:

y=2x

Step-by-step explanation:

The equation for slop-intercept form is y=mx+b where m is the slope and b is the y-intercept.

2 represents the rise/over since you rise 2 units (up) and run 1 unit (to the right). So the slope is 2/1 or just 2, and then you multiply it by x to get 2x.

The line starts at the origin (0,0), so the y-intercept would be 0. They didn't say y=2x+0 because the + 0 wouldn't change the line.

The equation that represents a line on a graph can be determined using the slope-intercept form, y = mx + b. To find the equation, you need to determine the slope and the y-intercept.

The equation that represents a line on a graph can be determined using the slope-intercept form, y = mx + b. In this form, m represents the slope of the line and b represents the y-intercept (the point where the line intersects the y-axis).

To find the equation of the line shown on the graph, you need to determine the slope and the y-intercept. You can do this by selecting any two points on the line and using their coordinates to calculate the slope, and then substituting one of the points into the equation to solve for the y-intercept.

Once you have the slope and y-intercept values, you can substitute them into the slope-intercept form to write the equation of the line.

divide both sides by 0.7 and you get 1.4286 gallons

The chemist needs to add approximately 1.43 gallons of distilled water to 5 gallons of acid to obtain a 70% pure tannic acid solution.

Here, we have,

To solve this problem, we can use a mixture equation that equates the amount of pure tannic acid in the initial solution to the amount of pure tannic acid in the final solution.

Let's denote the amount of distilled water to be added as "x" gallons.

The initial solution contains 5 gallons of acid at 90% purity. This means it contains 0.90 * 5 = 4.5 gallons of pure tannic acid.

When the distilled water is added, the total volume of the solution becomes 5 + x gallons.

The goal is to obtain a 70% pure solution, which means it should contain 0.70 * (5 + x) gallons of pure tannic acid.

According to the mixture equation, we can set up the following equation:

4.5 = 0.70 * (5 + x)

Now, let's solve for x:

4.5 = 0.70 * 5 + 0.70 * x

4.5 = 3.5 + 0.70x

0.70x = 4.5 - 3.5

0.70x = 1

x = 1 / 0.70

x ≈ 1.43

Therefore, the chemist needs to add approximately 1.43 gallons of distilled water to 5 gallons of acid to obtain a 70% pure tannic acid solution.

Answer:

x=11

Step-by-step explanation:

M is the midpoint this means that we can set AM and BM equal to eachother, once this is done we can solve for x

9x-6=6x+27 (set equal to eachother)

9x=6x+33 (add 6)

3x=33 (subtract 6x)

x=11 (divide by 3)

Midpoint M of AB splits AB into two equal segments. By solving given equation, we find that x = 11, AM = 93 and BM = 93.

The question pertains to the concept of midpoints in geometry. In this problem, we are given that M is the midpoint of AB. Since M is the midpoint, AM equals BM. So, we can set up the equation 9x - 6 = 6x + 27. Solving this equation we get x = 11. Substituting x = 11 into AM = 9x - 6, we get AM = 9(11) - 6 = 93. Similarly, substituting x = 11 into BM = 6x + 27, we get BM = 6(11) + 27 = 93. Therefore, both AM and BM equal 93.

y = 2(x - 3)² + 5

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (3, 5) and a = 2, hence

y = 2(x - 3)² + 5 ← in vertex form

The equation of the quadratic function in vertex form with given vertex and leading coefficient is y=2(x-3)²+5.

The vertex form of a quadratic function is f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. The coefficient a determines whether the graph of a quadratic function will open upwards or downwards.

Given that, the vertex is at (3,5) and has a leading coefficient of 2

Here, (h, k) = (3, 5) and a = 2

Substitute (h, k) = (3, 5) and a = 2 in f(x) = a(x - h)² + k, we get

y=2(x-3)²+5

Therefore, the equation of the quadratic function in vertex form is y=2(x-3)²+5.

To solve triangle ABC, we use the Law of Cosines to find angle C and the Law of Sines to find angles A and B. Plugging in the given values, we find that angle C is approximately 103.39 degrees, angle A is approximately 25.70 degrees, and angle B is approximately 50.91 degrees.

Given that c = 82, b = 2, and a = 12, we can use the Law of Cosines to solve for the missing angles.

Using the Law of Cosines, we have:

c^2 = a^2 + b^2 - 2ab*cos(C)

Plugging in the values, we get:

82^2 = 12^2 + 2^2 - 2(12)(2)*cos(C)

6724 = 144 + 4 - 48cos(C)

660 = -48cos(C)

cos(C) = -660/48

C = acos(-660/48)

Using a calculator, we find that C ≈ 103.39 degrees.

To find angle A, we can use the Law of Sines:

a/sin(A) = c/sin(C)

Plugging in the values, we get:

12/sin(A) = 82/sin(103.39)

Solving for sin(A), we get:

sin(A) = (12*sin(103.39))/82

A = asin((12*sin(103.39))/82)

Using a calculator, we find that A ≈ 25.70 degrees.

Finally, we can find angle B using the fact that the sum of the angles in a triangle is 180 degrees:

B = 180 - A - C

Plugging in the values, we get:

B = 180 - 25.70 - 103.39

Using a calculator, we find that B ≈ 50.91 degrees.

A ≈ 25.70 degrees

B ≈ 50.91 degrees

C ≈ 103.39 degrees

To solve the triangle ABC, we can use the Law of Sines. The Law of Sines states. the correct answer is:option b. A≈9.59°, B≈88.41°, c≈12.17°

To solve the triangle ABC, we can use the Law of Sines. The Law of Sines states:

sinA/a = sinB/b=sinC/c

Given that C=82°, b=2, and a=12, we want to find angles A and B and side

Let's find angle A using the Law of Sines:

sinA/12=sin82°/2

Now, solve for angle A:

sinA=12⋅ sin82°/2

A=sin −1(12⋅ sin82°/2)

A≈9.59°

Now that we have angle A, we can find angle B using the fact that the sum of angles in a triangle is 180°:

B=180°−A−C

B=180°−9.59°−82°

B≈88.41°

Now, we can find side c using the Law of Sines:

sinA/a= sinC/c

sin9.59°/12= sin82°/c

Now, solve for c:

c=12⋅sin82°/ sin9.59°

c≈12.17

A≈9.59°,

B≈88.41°,

c≈12.17°

Step-by-step explanation:

The fare for the Uber

Cost= 5+ .5 m  

where m is the number of miles

We spent 11.50

11.50 = 5 + .5 m

Subtract 5 from each side

11.5 -5 = 5+.5m -5

Divide by .5 on each side

6.5/.5 = .5m/.5

13 = m

We went 13 miles

Answer:

x = 11

Step-by-step explanation:

the line x + 5 is a mid segment of the triangle and thus is half the length of 3x - 1, that is

x + 5 = [tex]\frac{1}{2}[/tex](3x - 1)

multiply both sides by 2 to eliminate the fraction

2x + 10 = 3x - 1 ( subtract 3x from both sides )

- x + 10 = - 1 ( subtract 10 from both sides )

- x = - 11 ( multiply both sides by - 1 )

x = 11

Answer:

Total discount = $39.50

                  or 46.47 %

Step-by-step explanation:

First we need to figure out what she will pay for the shoes.  She is getting 30 percent off the 65 dollars.

Discount = price * percent off

                = 65*.3

                = 19.50

The cost of her shoes is the price minus the discount.

Cost = 65- 19.5

        = 45.50

To find the total discount, take the original price and subtract the final cost.

Total discount = 85-45.50

                        = 39.50

To find the total percent discount, we use the formula

      total percent discount = (original - final)/original * 100

                                             = (85- 45.50)/85 * 100

                                             = 39.5/85*100

                                              = 46.47%

Answer:

65

Step-by-step explanation:

let the son's age be x then the man's age is 5x

In 13 years

son's age = x + 13 and man's age = 5x + 13 and he is 3 times as old as son

5x + 13 = 3(x + 13)

5x + 13 = 3x + 39 ( subtract 3x from both sides )

2x + 13 = 39 ( subtract 13 from both sides )

2x = 26 ( divide both sides by 2 )

x = 13 ← son's present age

5x = 5 × 13 = 65 ← man's present age

Answer:

The man's present age is 65.  

Step-by-step explanation:

Let x = the man's age and y = his son's age.

In 13 yr, their ages will be x + 13 and y + 13, respectively.

We have two conditions:

(1)          x = 5y

(2) x + 13 = 3(y + 13)     Remove parentheses

    x + 13 = 3y + 39      Subtract 13 from each side

(3)        x = 3y + 26      Substitute (1) into (3)

         5y = 3y + 26      Subtract 2y from each side

         2y = 26              Divide each side by 2

(4)        y = 13                Substitute (4) into (1)

           x = 5 × 13

           x = 65

The man's present age is 65.

To calculate the different ice cream desserts Rachel can order, we use the formula for combinations without repetition. Given 5 sizes, 2 flavors, and 1 topping, the number of choices for each category: 5 sizes x 2 flavors x 1 topping = 10 different ice cream desserts Rachel could order.

Total ice cream desserts = (Number of sizes) × (Number of flavors) × (Number of toppings)

= 5 × 2 × 1

= 10

So, Rachel could order 10 different ice cream desserts by combining the choices for size, flavor, and topping.
