Suppose a camper took 2 h to ride around a resevoir at 10 mi/h at the beginning of the summer. By the end of the summer, she can ride around the resevoir in 1
h. What is her rate at the end of the summer?
A. 30 mi/h
B. 0.35 mi/h
C. 13.3 mi/h
D. 9.5 mi/h

Answers

Answer 1

Her rate at the end of the summer is 20 miles per hour.

What is her rate at the end of the summer?

We can define the rate in this case as the change in position as a function of the time.

So, the rate would be something like a speed (exactly a speed, actually).

Initially, the camper travles at a rate of 10mi/h in 2 hours, so the total distance is:

d = (10mi/h)*2h = 20mi

And at the end of the sumer, the camper travels that distance in one hour, so the rate at the end of the summer is:

R = 20mi/1h = 20mi/h

For the first question, the combinations of bananas and apples that Elena could buy for exactly $3.50 are:

2 bananas and 2 apples (A)

5 bananas and 1 apple (F)

For the second question, Andre's statement is incorrect. The first type of bus holds 50 people and the second type of bus holds 56 people. In total, 3 of the first type of bus and 3 of the second type of bus can only hold 3 * 50 + 3 * 56 = 318 people. However, there are 280 elementary school students and 40 adults, which is a total of 280 + 40 = 320 people. Hence, Andre's statement is incorrect.

For the third question, the reason why equations A and B are not equivalent is because the variables in Equation B are expressed in a different form than in Equation A. Equation A shows the relationship between the variable x and the constant value 13 and 48, while Equation B only shows the relationship between the variable x and the constant value 35. To determine if they are equivalent, we need to solve both equations for x and compare the solutions. Solving Equation A gives us x = (48 + 13) / -5 = 5.6. Solving Equation B gives us x = 35 / 5 = 7. Since the solutions are different, the equations are not equivalent.

find parametric equations for two circles c1 and c2 in space such that ¥c1 and c2 have the same radius; ¥c1 and c2 intersect at the points p(2,1,1) and q(2,1,1) and nowhere else.

Answers

The parametric equations for the two circles are

c1(t) = R cos(t) i + R sin(t) (0, 1, 0) + (2, 1, 1),c2(t) = R cos(t) (1, 0, 0) + R sin(t) (0, 1, 1)/√2 + (2, 1, 1).

How to find the parametric equations

A general parametric equation for a circle can be given as:

c(t) = R cos(t) i + R sin(t) j + k,

where

R is the radius and (i, j, k) is a unit vector perpendicular to the plane of the circle.

We can find two unit vectors perpendicular to the plane containing points p and q:

v1 = (1, 0, 0) and v2 = (0, 1, 1)/sqrt(2)

Thus, the two circles c1 and c2 with radius R and intersecting at p and q can be represented as:

c1(t) = R cos(t) i + R sin(t) (0, 1, 0) + (2, 1, 1),

c2(t) = R cos(t) (1, 0, 0) + R sin(t) (0, 1, 1)/√2 + (2, 1, 1).

A function is something that connects an input to an output.

Then, they are interpolated over entire elements using shape functions, which are essentially polynomials of different orders. Although quadratic shape functions, like a quadratic curve, are becoming common, linear shape functions, like a straight line used to approximate a distance between two locations, are the most fundamental. Even higher order shape functions (like cubic) exist, but they are rarely used in practical settings. The calculation of an element's stress uses Gauss Points rather than nodes.

The probability of a couple having five children with no children being affected by the disorder is given by the formula (1 - 0.0025)⁵.

This formula calculates the probability of a certain event (in this case, having no children affected by the disorder) happening five times in a row. However, this does not give the probability of all five children being unaffected by the disorder.

To find the probability of all five children being unaffected, you would need to multiply the probability of each child being unaffected, which is (1 - 0.0025), five times:

(1 - 0.0025) * (1 - 0.0025) * (1 - 0.0025) * (1 - 0.0025) * (1 - 0.0025) = 0.99609

Answers

The solution of the periodic function is explained below.

A periodic function is a function that repeats its values after a certain interval of time, called its period.

The periodic function f(t) is defined on its period –2 ≤ t ≤ 2 and is described by the formula:

f(t) = t^2, when -2 ≤ t < 0

f(t) = -t^2, when 0 ≤ t ≤ 2

a) Plotting the function on the interval -8 ≤ t ≤ 8 would show us the repeating pattern of the function. To plot the function, we need to evaluate it for different values of t and plot the corresponding points on the coordinate plane.

b) The period of the function can be found by determining the smallest interval in which the function repeats. In this case, the period of the function is 2.

c) To determine whether the function is odd or even, we need to check if f(-t) = f(t) or f(-t) = -f(t). In this case, the function is an even function as f(-t) = f(t).

d) The mean value of the function on its period can be found by finding the average value of the function over one period. This is given by the formula:

(1/period) * ∫_0^period f(t) dt

e) The Fourier coefficients of the function can be found by using the formula:

ak = (2/period) * ∫f(t) cos(kπt/period) dt

bk = (2/period) * ∫f(t) sin(kπt/period) dt

f) The Fourier series of the function can be found by using the Fourier coefficients. This is given by the formula:

=> f(t) = a0/2 + ∑_(n=1)^∞

solve the system linaer equations by elimlnation x-2y=7 3x+2y=3

Answers

Answer:

x-2y=7

Step-by-step explanation:

Can anyone help on this?

Answers

Step-by-step explanation:

we need Pythagoras and a little bit of open mind.

Pythagoras is

c² = a² + b²

with c being the Hypotenuse (side opposite of the 90° angle), a and b being the legs.

the incenter means that it is the center point of the inscribed circle (being totally inside the triangle and touching every side at exactly one point).

that means that

GF = GB = GD

but GF we know : 22

so, GB = 22

now we can use the right-angled triangle ABG to find AG :

AG² = AB² + GB²

AG² = 32² + 22² = 1024 + 484 = 1508

AG = sqrt(1508) = sqrt(4×13×29) = 2×sqrt(377) =

= 38.83297568...

45
AB=16, AC=16
AB= 6, AC= 6√/2
BC=7√2, AC = 14
AB= 15, BC = 15
OBC=8, AC = 8√3
AB= 11, AC = 22

Answers

The possible measurements for the triangle are given as follows:

AB = 6, AC = 6√2.AB = 15, BC = 15.

What are the trigonometric ratios?

The three trigonometric ratios are defined as follows:

Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.

For this problem, we have an angle of 45º, which has the same value for sine and cosine, hence:

AB = BC.AC = AC√2.

? what quantitative rule may be used to determine univariate outliers, and are there situations in which deleting a case/participant may be justified?

Answers

The Interquartile Range (IQR) rule is a commonly used quantitative rule to determine univariate outliers and deleting a case may be justified if it is a result of a measurement error, data entry error, or if it significantly skews the results.

The Interquartile Range (IQR) rule is a commonly used method for identifying outliers in a univariate data set. It is calculated as the difference between the 75th percentile (Q3) and the 25th percentile (Q1). Outliers are considered to be any values that fall outside of the range Q1 - 1.5 * IQR to Q3 + 1.5 * IQR. This range encompasses approximately 75% of the data, with outliers being any values that fall outside of this range.

In some cases, deleting a case or participant may be justified if it is a result of a measurement error, data entry error, or if it significantly skews the results.

This decision should be made carefully and only after careful consideration of the implications, as removing data can affect the validity of the results and the conclusions that can be drawn from the analysis. In some cases, it may be better to keep the outlier and consider it a potential error or to conduct further analysis to determine if there is a valid reason for the outlier.

(FOR 100 POINTS!) MY ANSWER PROBABLY WASNT RIGHT, JUST COMMENT THE CORRECT THING IN SIMPLEST RADICAL FORM.

Answers

This is the Pythagorean theorem, A^2+B^2=C^2

Since all corresponding sides are the same, 3 rad 2, squared twice and added would equal to x.

Answer:

6

Your answer is correct, but since √1 = 1

we can simplify this as 6 · 1 = 6

Step-by-step explanation:

Since the given figure is a square, all four sides are equal.

Each side = 3√2

For a square of side a, the diagonal is given by

d = √(a²+a²) = √(2a²) = a√2

Here we have a = 3√2

So diagonal = x = 3√2 (√2) = 3 · 2 = 6
