center:(−15, −21);
point on the circle: (0, −13)

The circumference is about ?

Answers

Answer 1

Answer:

Circumference ~ 106.8

Step-by-step explanation:

Use the distance formula to find the radius of the circle with the two coordinates given. The radius of this circle is 17. Plug 17 into the formula 2(pi)r to find the Circumference. The answer is 106.8 rounded to the nearest tenth.

(The answer must come Rs. 5950)
plz anyone ASAP help. ​

Answers

Answer:

The answer given is incorrect

The correct answer is Rs. 3640

The total cost of the paper required to cover one-half of the wooden cone is Rs. 3846.5.

What is the surface area of a cone?

The surface area of a cone is given by the formula:

surface area = π x r x s

where r is the radius of the base of the cone and s is the slant height of the cone. The slant height of the cone is the distance from the apex of the cone to the base, measured along the surface of the cone.

In this case, the diameter of the base of the cone is 14 cm, so the radius is half the diameter or 14 cm / 2 = 7 cm.

The vertical length of the cone is 24 cm, so the slant height of the cone is the square root of the vertical length squared plus the radius squared:

s = √(24² + 7²)

s = √(576 + 49)

s = √(625)

Which simplifies to:

s = 25 cm

Now that we have the radius and slant height of the cone, we can use the formula for the surface area of a cone to find the surface area of one-half of the cone:

surface area = π x 7 cm x 25 cm = 175π cm²

To find the total cost of the paper required, we need to multiply the surface area by the cost per square centimeter:

total cost = 175 x 3.14 cm² x  Rs.7/cm² = Rs. 3846.5

Therefore, the cost of the paper needed to cover one-half of the wooden cone is Rs. 3846.5.

carter has 37 coins, all nickels and dimes in his piggy bank. The value of the coins is $3.17. How many dimes does carter have?

Answers

n = nickels, d = dimes
Make a system of equations
( n + d = 37 ) 0.05
0.05n + 0.10d = 3.17

can someone please help me find the slope on khan academy? and please provide an explanation if possible

Answers

Answer: 7/4

Step-by-step explanation: To find the slope of a line, pick any two integer points, in this scenario the only two are (3,4) and (-1,-3). The slope is the rise over run, so think about it. To get from (-1,-3) to )3,4) you need to rise 7 units (difference in y coordinates) and from there you need to run 4 units, so it is 7/4. Keep in mind that rising up is positive for y and running to the right is positive for x.

Answer:

[tex]\frac{7}{4}x[/tex]

Step-by-step explanation:

How do you find slope on a graph? The slope is "rise/run" where "rise" is how much y spaces are moved to the next point and "run" is the how much spaces are moved to the next x point.

Step One: In this case, the point moves up 7 spaces to the next point, so that's the "rise" and then it moves 4 spaces to the right to the next point, so that's the "run"

Step Two: When we put it together, it is 7/4x. The x is just an indication that this is slope, and you don't have to worry about it until you learn how to plug it in.

Write the quadratic equation in standard form:
4x2 + 5x + 10 = 2x

Answers

Answer:
3x = -18
This should be the answer let me know if I’m wrong.

The quadratic equation 4x² + 5x + 10 = 2x in standard terms can be written as 4x² + 3x + 10 = 0.

A quadratic equation is of the form ax² + bx + c = 0, where a is the coefficient of x², b is the coefficient of x and c is the constant term. Such equations are called quadratic because the degree of the equation is 2 as the highest power of the polynomial is 2. Such equations have 2 roots, whose sum equals [tex]-\frac{b}{a}[/tex] and their product is equal to [tex]\frac{a}{c}[/tex].

Some examples of quadratic equations are 2x² + 3x - 1, 4x² + 16x + 4, etcectra.

The given quadratic equation is 4x² + 5x + 10 = 2x.

4x² + 5x + 10 = 2x

4x² + 5x - 2x + 10 = 2x - 2x

4x² + 3x + 10 = 0.

Hence, in the standard form, the quadratic equation 4x² + 5x + 10 = 2x can be written as 4x² + 3x + 10 = 0.

Regan cycles 78 miles in 6 hours. His average speed for the first 30 miles is 15 miles per hour. Work out Regan's average speed for the last 48 miles.

Answers

Answer:

12 mph

Step-by-step explanation:

Given that:

Total distance traveled = 78 miles

Time taken, t = 6 hours

Average speed for first 30 miles = 15 mph

Time taken = distance / speed

Time taken = 30 / 15

Time taken = 2 hours

Average speed for last 48 miles = x

Time taken to travel last 48 miles = (6 - 2) = 4 hours

Average speed for last 48 miles :

Distance traveled / time taken

48 miles / 4 hours

= 12 mph

A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are common in mathematics and are required for the formulation of physical relationships in the sciences.

We have,

Function, f(x) = x²

The function g(x) is compressed horizontally by a factor of 3, to get the function g(x)
