Find Area Of Circle

Answers

Answer 1

Answer:

should be 314.16 possible that is incorrect because I calculated it by pie and not by 3.

Answer 2

Answer:

A = 314 cm^2

Step-by-step explanation:

A = pi x r^2

A = 3.14 x (10 x 10)

A = 3.14 x 100

A = 314 cm^2

Aline has an x-intercept of 3 and a y-intercept of -6.
The slope-intercept form of its equation is

Answers

(0,6) & (3,0)

m = (y2-y1)/(x2-x1)

m = (0-6)/(3-0)

m = -6/3

m = -2

Substitute the values in y = mx + c

0 = -2(6) + c

c = 12

Thus, the equation is y = -2x + 12

Answer:

y=2x-6

Step-by-step explanation:

You can plug this into the slope formula, x-intercept of 3 would be (3,0)

and y intercept of -6 would be (0,-6).  

Find the slope using the slope formula. The slope is 2

We are given a y-intercept of -6

therefore, the answer is y=2x-6

The paraboloid z = 3 − x − x2 − 2y2 intersects the plane x = 1 in a parabola. Find parametric equations in terms of t for the tangent line to this parabola at the point (1, 3, −17). (Enter your answer as a comma-separated list of equations. Let x, y, and z be in terms of t.

Answers

Answer:

the required parametric equation is:

x = 1

y = t + 3

z = -12t - 17

Step-by-step explanation:

From the given information:

We are to express x,y, and z in terms of t.

The purpose of this question is to find the parametric equations in terms of t.

Given that the tangent line related to the parabola is the point (1,3, -17)

Provided that the paraboloid z = 3 - x - x² - 2y² intersect the plane x = 1 in a paraboloid; then:

z = 3 - 1 - (1)² - 2y²

z = 1 - 2y²

Suppose y = t, then the parametrization is given by:

(x (t), y(t), z(t) ) = (1, t, 1 - 2t²)

(x' (t), y'(t), z'(t) ) = (0,1, -4t)

At the point (x,y,z) = (1,3, -17)

For t (=y) = 3

Hence, (x'(3),y'(3),z'(3)) = (0,1, -12)

Therefore, the equation of the tangent line can be expressed as:

[tex]\dfrac{x-1}{0}=\dfrac{y-3}{1}=\dfrac{z-(-17)}{-12}=(t)[/tex]

x - 1 = 0, y -3 = t, z + 17 = -12t

x = 1, y = t + 3 , z = -12t - 17

Thus, the required parametric equation is:

x = 1

y = t + 3

z = -12t - 17

A restaurant has two different seating options: a table and a family booth. A table can seat 4 people, and a family booth can seat 10 people. The restaurant has a maximum capacity of 242 people. If the restaurant has 19 family booths, which inequality could be used to find t, the number of tables in the restaurant?

Answers

Answer: 242 = 190 + 4t

Step-by-step explanation:

You know that the maximum capacity of the restaurant is 242 people, meaning that at most there can only be that many customers seated at that time. Normally, the equation would be 242 = 10b + 4t, but since you already know the number of booths, your work is cut in half, giving you 242 = 10(19) + 4t. The equation would be this because you have the capacity being equal to the number of tables x the number of people at each table and the number of booths x the number of people seated at each of them.

suppose you are organizing a party and have a budget of b dollars for the appetizers. You plan to order v vegetarian spring rolls at $0.75 each and s shrimp rolls at $0.95 each.

The equation 0.75v+0.95s=b represents this constraint.

Solve 0.75v+0.95s=b for v

When would it be most helpful to use this equation?

Answers

Answer:

v = b/0.75 - 0.95s/0.75

Or

v = (b - 0.95s) / 0.75

Step-by-step explanation:

Solve 0.75v + 0.95s = b for v

This means making v the subject of the formula

0.75v + 0.95s = b

Subtract 0.95s from both sides

0.75v + 0.95s - 0.95s = b - 0.95s

0.75v = b - 0.95s

Divide both sides by 0.75

v = (b - 0.95s) / 0.75

v = b/0.75 - 0.95s/0.75

The equation will be useful in determining the number of vegetarian

Graph the line with the slope of 3/5 and goes through the point (1,2)

Answers

Answer:

Here's a screenshot of the correct line:

The line with the slope of 3/5 and goes through the point (1,2) is y = 3/5x + 7/5

The equation of a straight line is given by:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Given the line has a slope of 3/5 and goes through the point (1,2). The equation of the line is given by:

Isabella wants to order the race times from her slowest time to her fastest time. Sort the decimals in order from greatest to least.

Answers

Given:

Number of 100-meter races = 5

The time it took Isabella to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.08, and 12.087.

To find:

The decimals in order from greatest to least.

Solution:

The time it took Isabella to complete each race, in seconds, was shown below:

12.7, 12.807, 12.78, 12.08, 12.087

We need to arrange this data in descending order.

In all 5 numbers the digits before decimals are same. On comparing the digits on the tenth place and hundredth place, we get

12.807 > 12.78 > 12.7 > 12.087 > 12. 08

Therefore, the required order of given data is 12.807, 12.78, 12.7, 12.087, 12. 08.
