A tire has a radius of 20 inches. What is the Circumference of the tire?

C=πd

Answers

Answer:

125.6637061

Step-by-step explanation:

Answer:

40π inches, or approximately 125.66 inches

Step-by-step explanation:

The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14.

In this case, the radius of the tire is 20 inches. So, the circumference of the tire is:

C = 2πr

C = 2π(20)

C = 40π

Therefore, the circumference of the tire is 40π inches, or approximately 125.66 inches if you round to two decimal places.

Marcella is flying a kite in a competition. To win the competition, her kite string must have at least 162 feet released. The kite is 75 feet above her. The angle of the string and her hand is forming a 28 degree angle. Will she be able to win the competition? Show your work.


For question 1, will she win the competition? Type yes or no

Answers

Marcella won't be able to win the competition because the length of the rope is less than 162 feet.

How to find the sides of a right angle triangle?

The situation forms a right angle triangle.

The kite released rope is the hypotenuse side of the triangle formed.

The opposite side of the triangle is the height of the kite from the ground.

Therefore,

sin 28 = opposite / hypotenuse

sin 28 = 75 / h

h = 75 / sin 28

h = 75 / 0.46947156278

h = 159.754085116

h ≈ 160 feet

Therefore, she won't be able to win the competition because the length of the rope is less than 162 feet.

una recta pasa por los Puntos (-3,-1)y es paralela a la recta que pasa por los Puntos D (4,-6)y E(-4,4)

Answers

The equation of the line that passes through (-3, -1) and is parallel to the line passing through D (4, -6) and E (-4, 4) is y = (-5/4)x - 19/4.

To find the equation of a line that passes through the point (-3, -1) and is parallel to the line passing through points D (4, -6) and E (-4, 4), we can follow these steps:

Calculate the slope of the line passing through points D and E:

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

Slope = (4 - (-6)) / (-4 - 4)

Slope = 10 / (-8)

Slope = -5/4

Since the line we want to find is parallel to the line passing through D and E, it will have the same slope. So, the slope of the line we want to find is also -5/4.

We can use the point-slope form of a linear equation to determine the equation of the line passing through (-3, -1) with the slope -5/4:

y - y1 = m(x - x1)

where (x1, y1) is the given point (-3, -1) and m is the slope (-5/4).

Plugging in the values, we get:

y - (-1) = (-5/4)(x - (-3))

y + 1 = (-5/4)(x + 3)

Simplify the equation:

y + 1 = (-5/4)x - 15/4

Move the constant term to the other side:

y = (-5/4)x - 15/4 - 1

y = (-5/4)x - 15/4 - 4/4

y = (-5/4)x - 19/4

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.

\(4-2x-14=3x+15\)

simplifying the equation by subtracting 14 from the L.H.S

\(-10-2x=3x+15\)

Subtracting 15 from both sides

\(-10-2x-15=3x+15-15\)

\(-25-2x=3x\)

combining the like terms

\(-25=3x+2x\)

\(-25=5x\)

\(-5=x\)

Let f be a continuous function on the closed interval [0, 2] . If 2 ≤ f(x) ≤ 4, then the greatest
possible value of (integral from 0 to 2)f(x)dx is

a. 0
b. 2
c. 4
d. 8
e. 16

Answers

The correct answer is d. 8, as it represents the greatest possible value for the integral of f(x) over the interval [0, 2].

Given that 2 ≤ f(x) ≤ 4 for all x in the interval [0, 2], we know that the function f(x) is bounded between 2 and 4 throughout the interval. To find the greatest possible value of the integral of f(x) over the interval [0, 2], we want to maximize the area bounded by the function and the x-axis.

Since the function is continuous and bounded, we can use the Fundamental Theorem of Calculus to find the integral. The integral of f(x) over the interval [0, 2] represents the area under the curve of f(x) between x = 0 and x = 2.

The maximum possible value of this integral occurs when the function is at its upper bound of 4 throughout the interval. Therefore, the greatest possible value of the integral is the area of the rectangle with a base of 2 (the width of the interval) and a height of 4, which is 2 * 4 = 8.

Hence, the correct answer is d. 8, as it represents the greatest possible value for the integral of f(x) over the interval [0, 2].

Answers

The most quickly revealing form for finding the y-intercept of the function ggg is Choice A. The y-intercept represents the point where the graph of the function intersects the y-axis, which occurs when the value of x is 0.

In Choice A, the function is given as g(x) = -2(x+1)(x+7). By substituting x = 0 into the function, we can find the y-intercept. When x = 0, the expression becomes g(0) = -2(0+1)(0+7) = -2(1)(7) = -14. Therefore, the y-intercept is (0, -14). Choice B and Choice C also provide equivalent forms of the function ggg, but they do not directly reveal the y-intercept as quickly as Choice A.

To find the y-intercept, substitute x = 0 into the equation and evaluate. The y-intercept is -14 in all three forms of the given function.

The y-intercept of a function is the point where the graph of the function intersects the y-axis, which occurs when x is equal to zero. To find the y-intercept in each form of the function, substitute x = 0 into the equation and evaluate:

Form A: g(0) = -2(0 + 1)(0 + 7) = -2(1)(7) = -14Form B: g(0) = -2(0 + 4)^2 + 18 = -2(4)^2 + 18 = -2(16) + 18 = -32 + 18 = -14Form C: g(0) = -2(0)^2 - 16(0) - 14 = -2(0) - 16(0) - 14 = 0 - 0 - 14 = -14

What is the degree measure of each angle expressed in radians? What is the radian measure of each angle expressed in degrees? (Express radian measures in terms of π .)


a. π /2 radians

Answers

π/2 radians is equivalent to 90 degrees. Radians measure angles based on the ratio of arc length to radius in a circle.

Radians and degrees are two different units used to measure angles.

In a circle, there are 2π radians (approximately 6.28) for a full revolution, which is equivalent to 360 degrees.

a. To determine the degree measure of π/2 radians, we can use the fact that 2π radians is equivalent to 360 degrees.

Solving for the unknown angle, we can set up the proportion: (π/2) radians = x degrees / 360 degrees. Cross-multiplying gives us x = (π/2) * (360/1) = 180 degrees.

Therefore, π/2 radians is equivalent to 180 degrees.

Radian measure represents the size of an angle in terms of the ratio of the arc length to the radius.

Each radian corresponds to an angle subtended by an arc that has a length equal to the radius of the circle.

Answer:

Step-by-step explanation:

When you take the n-th root of a number, you can rewrite the expression by taking it to the 1/n-th power. For example:

\(\sqrt[n]{x} =x^\frac{1}{n}\)

For the first expression, we can use this proprtery to get:

\(\sqrt[5]{a^x} =(a^x)^\frac{1}{5}\)

Using exponent rules, you can combine the exponents by simply multiplying them to get:

\(a^\frac{x}{5}\)

Moving on to the second expression. It is now the square root, or equivalently a 1/2 power. If we break up the terms under the radical into powers of 2, we can cancel a lot of the terms:

\(\frac{\sqrt{81a^3b^1^0} }{\sqrt{3}a } =\frac{\sqrt{81a^2*a*b^1^0} }{\sqrt{3}a }\)

The a^2 and b^10 can be taken out of the radical because they have perfect roots:

\(\frac{\sqrt{81a^2*a*b^1^0} }{\sqrt{3}a }=ab^5\frac{\sqrt{81a} }{\sqrt{3}a }\)

The square root of 81 has a perfect root of 9. We have:

\(ab^5\frac{\sqrt{81a} }{\sqrt{3}a }=9ab^5\frac{\sqrt{a} }{\sqrt{3}a }\)

You can divide 9 and the square root of 3 by breaking up 9 into a product:

\(\frac{(3*3)ab^5}{\sqrt{3} } \frac{\sqrt{a} }{a }=3\sqrt{3} ab^5\frac{\sqrt{a} }{a }\)

Simply by cancelling the 'a' terms to get:

\(3\sqrt{3} ab^5\frac{\sqrt{a} }{a }={3\sqrt{3}}\sqrt{a}b^5=3b^5\sqrt{3a}\)

Answers

Interest = A - (50 * 456)

To determine how much you will have in the IRA when you retire at age 65, we can use the formula A = P[(1 + r)^t - 1] / r, where A is the future value, P is the monthly deposit, r is the monthly interest rate, and t is the number of months.

a. In this case, the monthly deposit is 50, the monthly interest rate is 5% or 0.05, and the number of months is (65 - 27) * 12 = 456 (from age 27 to 65).

Using the formula, we can calculate:
A = 50[(1 + 0.05)^456 - 1] / 0.05
