A conversion of 300 degrees to radians is equal to 5.24 radians.
How to determine the angle in radians?In Mathematics and Geometry, you will have to divide the central angle that is subtended by the arc of a circle by 360 degrees if you want to calculate the arc length formed by a circle, and then multiply this fraction by the circumference of the circle.
Mathematically, the arc length formed by a circle can be calculated by using the following equation (formula):
Arc length = rθ
Where:
r represents the radius of a circle.θ represents the central angle measured in degrees.Next, we would convert degrees to radians;
300 = rads × 180/π
Radians = 300π/180 = 5.24 radians.

Determine whether the pairs of vectors is orthogonal
No, the pairs of vectors 3i - 8j, 8i - 3j are not orthogonal.
What is the dot product of the pair of vectors?The dot product will help us to determine if the pair of vectors are orthogonal or not.
If the dot product is equal to zero, then the pair of vectors are orthogonal.
The dot product of the vectors is calculated as follows;
(3i - 8j).(8i - 3j)
= (3i x 8i) - (3i x 3j) - (8j x 8i) + (8j x 3j)

You want to purchase a new bike that costs $125.99. To save for the bike, you mow your neighbor's yard for $40 each week. How much money will you have left over if you buy the bike after saving for 4 weeks?
Answer: $34.01
Step-by-step explanation:
To get the answer, we must first add up the entire amount of money saved after four weeks of mowing the neighbor's lawn, then subtract the bike's price.
Since we get $40 a week, after 4 weeks we will have saved the following:
40 × 4 = 160
We will therefore have $160 to spend on the bike. The bike costs $125.99, so we will have the following amount of money after purchasing the bike:
160 - 125.99 = 34.01
Therefore, after purchasing the bike, we will have $34.01 leftover.

There is not enough evidence to support the claim that more than 20% of users develop nausea at a 0.01 significance level.
We have,
Based on a sample of 217 subjects, 53 of them developed nausea.
To test this claim, a hypothesis test is conducted using a significance level of 0.01.
The null hypothesis, denoted as H0, assumes that the true proportion of users who develop nausea is less than or equal to 20%, while the alternative hypothesis, denoted as Ha, assumes that the true proportion is greater than 20%.
If the test statistic, calculated from the sample data, falls in the rejection region, which is determined based on the significance level and the degrees of freedom, then the null hypothesis is rejected, and it can be concluded that there is sufficient evidence to support the alternative hypothesis.
In this case,
If the test statistic falls in the rejection region, it means that the evidence suggests that more than 20% of users of the pain drug develop nausea, and the claim that less than or equal to 20% of users develop nausea is not supported by the data.

The vertex form of the quadratic function f(x) = 2x^2 + 8x + 7 is f(x) = 2(x + 2)^2 - 25.
How to find the vertex formTake a look at the quadratic function:
f(x) = 2x^2 + 8x + 7
In this situation, a = 2 and b = 8, yielding:
f(x) = 2(x^2 + 4x) + 7
It shtbe noted that to determine the value to add and subtract, multiply (b/2a)2 by (8/2(2))2 = 42 = 16. Inside the parenthesis, we add and subtract 16:
f(x) = 2(x^2 + 4x + 16 - 16) + 7
The expression inside the parenthesis can now be written as a perfect square:
f(x) = 2((x + 2)^2 - 16) + 7

Selena took a pizza out of the oven, and it started to cool to room temperature (68°F). She will serve the pizza when it reaches 130°F. She took the pizza out at 5:00 P.M. Use regression to find when she can serve it.
Selena can serve the pizza at around 6:40 P.M.
How to explain the regressionThe regression line should have the equation y = -1.7x + 300, where y is the temperature, x is the time in minutes since the pizza was taken out of the oven, -1.7 is the slope of the line, and 300 is the y-intercept.
Set y (the temperature) to 130°F, and solve for x (the time).
130 = -1.7x + 300
-170 = -1.7x
x ≈ 100
According to the regression model, the pizza will reach 130°F after about 100 minutes after it was taken out of the oven. Therefore, Selena can serve the pizza at around:

Use the given circumference to find the surface area of the spherical object. a pincushion with C = 24 cm
Answer:
approximately 183.4 square centimeters.
Step-by-step explanation:
We can use the formula for the circumference of a sphere, which is:
C = 2πr
where C is the circumference and r is the radius.
We know that the circumference of the pincushion is 24 cm. We can use this to find the radius:
C = 2πr
24 = 2πr
r = 24/(2π)
r ≈ 3.82 cm
Now that we know the radius, we can use the formula for the surface area of a sphere, which is:
A = 4πr^2
Substituting the value we found for the radius, we get:
A = 4π(3.82)^2
A ≈ 183.4 cm^2
Therefore, the surface area of the pincushion is approximately 183.4 square centimeters.
