Caroline was out at a restaurant for dinner when the bill came. Her dinner came to $22. After adding in a tip, before tax, she paid $25.08. Find the percent tip.
Caroline paid 14% of the cost of the dinner as a tip.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Extra pay or tip = 25.08 - 22
= $3.08
Now,
Percentage of tip corresponding to the bill amount,
= 3.08 / 22 × 100
= 14%
Thus, Caroline paid 14% of the cost of the dinner as a tip.

Which statements are true about x? Select three options.
The element x is an illustration of sets and the true statements about x are: x ∈ B ∪ C, x ∈ B ∩ C and x ∈ A ∪ C
How to determine the true statements?From the Venn diagram in the complete question, we have the following highlights:
Element x is present in set BElement x is present in set CThe above means that:
The element is a common element in the intersection of sets B & C and in the union of sets B & C.
This is represented as:
x ∈ B ∪ C and x ∈ B ∩ C
Also, we can say that the element is a common element in the union of sets A & C and in the union of sets A & B.
This is represented as:
x ∈ A ∪ B and x ∈ A ∪ C
Hence, the true statements about x are: x ∈ B ∪ C, x ∈ B ∩ C and x ∈ A ∪ C

17. The velocity, in meters per second, of a runner is given by the function v(t)=11 et +5t. A. Find the acceleration of the runner at time t = 3 seconds. Include the proper units. B. Find the position function given that the runner starts at a distance of 6 meters.
Answer:
a) a= 5 m/s^2
b) P(t) = 2.5 t^2 + 11 t + 6
Step-by-step explanation:
The velocity function is V(t) = a*t + Vo
In this case: V(t) = 5t + 11
It means the constant acceleration a = 5 m/s^2
while the initial velocity (at time t=0s) is 11 m/s
The position function is:
P(t) = 1/2 A*t^2 + Vo*t + Po
In this case:
P(t) = 2.5 t^2 + 11 t + 6

Answer:
25.1Step-by-step explanation:
Before finding the value of x which is the base in the right triangle, we must have to find the perpendicular in the left angle triangle.
So, In the left triangle,
→ (Base)² + (Perpendicular)² = (Hypotenuse)²
→ (10)² + (Perpendicular)² = (16)²
→ (Perpendicular)² = (16)² – (10)²
→ (Perpendicular)² = 256 – 100
→ (Perpendicular)² = 156
→ Perpendicular = √(156)
→ Perpendicular = 12.4
Now, In the right triangle, we have :
→ (Base)² + (Perpendicular)² = (Hypotenuse)²
→ (x)² + (12.4)² = (28)²
→ (x)² = (28)² – (12.4)²
→ (x)² = 784 – 153.7
→ (x)² = 630.3
→ x = √(630.3)
→ x = 25.1
Therefore,
The value of x is 25.1determine the general solution

2. A light fixture contains 6 light bulbs. With normal use, each bulb has a 0.85
chance of lasting for at least 4 months. What is the theoretical probability that
all 6 bulbs will last for 4 months? Round to the nearest whole percent.
Using the binomial distribution, it is found that there is a 0.38 = 38% theoretical probability that all 6 bulbs will last for 4 months.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, we have that:
There are 6 bulbs, hence n = 6.Each bulb has a 0.85 chance of lasting for at least 4 months, hence p = 0.85.The probability that all 6 bulbs will last for 4 months is P(X = 6), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 6) = C_{6,6}.(0.85)^{6}.(0.15)^{0} \approx 0.38[/tex]

35-36 Use a graph to find approximate [tex]x[/tex] -coordinates of the points of intersection of the given curves. Then use your calculator to find (approximately) the volume of the solid obtained by rotating about the [tex]x[/tex] -axis the region bounded by these curves.
36. [tex]y=\sqrt[3]{2 x-x^{2}}, \quad y=x^{2} /\left(x^{2}+1\right)[/tex]
The approximate x-coordinates of the points of intersection of the given curves are 0 & 1.76, and the volume of the solid when rotated about the x-axis is 3.15 cubic units
Part A: The points of intersectionThe equations are given as:
y = ∛2x - x²
y = x²/(x² + 1)
See attachment for the graph of the above curves (equation)
From the attached curve, we have the following points of intersection
(x,y) = (0,0) and (1.76,0.76)
Remove the y coordinates
x = 0 and 1.76
Hence, the approximate x-coordinates of the points of intersection of the given curves are 0 and 1.76
The volume of the solid when rotated about the x-axisThe volume of the solid is calculated using:
V = π(R² - r²)
Where R and r are the outer and the inner radii, respectively.
In this case;
R = ∛2x - x²
r = x²/(x² + 1)
Using a calculator, we have:
V = 3.15
Hence, the volume of the solid when rotated about the x-axis is 3.15 cubic units
