Answer:

58 = 3.5x + 2

Step-by-step explanation:

Since $3.50 is charged for every mile, we multiply x by 3.5 like this: 3.5x

$2 is already added on as a free so + 2

$58 is the total amount of money for all of the charges including the per mile and pick-up fee.

This was we can solve for the number of miles, x

58 = 3.5x + 2

- 2            - 2

56 = 3.5x

56/3.5 = 3.5x/3.5

x = 16

The taxi drove a total of 16 miles

The Graph is not linear.

To graph f, we graph the equation y = f(x). To this end, we use the techniques outlined in Section 1.2.1. Specifically, we check for intercepts, test for symmetry, and plot additional points as needed. To find the x-intercepts, we set y = 0. Since y = f(x), this means f(x) = 0. f(x) = x2−x−6 0 = x2−x−6 0 = (x−3)(x+2) factor x−3=0 or x+2=0 x = −2,3 So we get (−2,0) and (3,0) as x-intercepts. To find the y-intercept, we set x = 0. Using function notation, this is the same as finding f(0) and f(0) = 02 − 0 − 6 = −6. Thus the y-intercept is (0, −6). As far as symmetry is concerned, we can tell from the intercepts that the graph possesses none of the three symmetries discussed thus far. (You should verify this.) We can make a table analogous to the ones we made in Section 1.2.1, plot the points and connect the dots in a somewhat pleasing fashion to get the graph below on the right. y x f(x) (x, f(x)) −3 6 (−3,6) −2 0 (−2,0) −1 −4 (−1,−4) 0 −6 (0, −6) 1 2 3 4 5 6 7 −3−2−11 2 3 4 1 −6 (1, −6) 2 −4 (2, −4) 3 0 (3, 0) 4 6 (4, 6)

The 90% confidence interval for the sample mean is (13.289, 16.711). This means that we can be 90% confident that the true population mean lies within this interval based on the given sample.

To calculate a 90% confidence interval for a sample mean, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

First, we need to determine the critical value for a 90% confidence level. Since we have a sample size of 25, we can use a t-distribution. Consulting a t-table or calculator, for a 90% confidence level and 24 degrees of freedom (sample size minus 1), the critical value is approximately 1.711.

Next, we calculate the standard error using the formula:

Standard Error = Sample Standard Deviation / √(Sample Size)

Plugging in the values, we get:

Standard Error = 5 / √(25) = 1

Now, we can calculate the confidence interval:

Confidence Interval = 15 ± (1.711 * 1) = (13.289, 16.711)

The 90% confidence interval for the sample mean is (13.289, 16.711). This means that we can be 90% confident that the true population mean lies within this interval based on the given sample.

1. Let's review the information given to us to answer the question correctly:

Height of the Willis Tower in Chicago = 1,454 feet

Scale of the model = 2 inches : 45 feet height

2. How tall is the height?

For answering that question, we will use the following expression:

Height of the model = Height of the Willis Tower in Chicago/Scale in feet * Scale in inches

Replacing with the real values, we have:

Height of the model = 1,454/45 *2

Height of the model = 32.31 * 2 = 64.62 inches

64.62 inches/12 = 5.39 feet

The model is 64.62 inches of height or 5.39 feet

The correct answer is b. Each block should consist of volunteers who live in similar environments when it comes to mosquitoes.

Explanation:

In a randomized block design, blocks are formed to control for potential confounding factors or sources of variation that may affect the outcome of the experiment. By forming blocks based on similar environments when it comes to mosquitoes, the researchers ensure that any differences in the effectiveness of the bracelet and bug spray are not solely due to variations in mosquito exposure.

If the researchers were to choose option a (both the volunteers and researchers should be kept blind as to which block the volunteers are in), it would be related to blinding the participants and researchers to the treatment assignment, not forming blocks. This method does not address the need for controlling potential confounding factors.

Option c (each block should consist of volunteers who live in different environments when it comes to mosquitoes) would not be suitable because it would introduce additional variability and make it difficult to compare the effectiveness of the bracelet and bug spray.

Option d (each volunteer should be randomly assigned to a block) is not recommended in this case because it does not take into account potential confounding factors related to mosquito exposure.

Option e (volunteers in one block should use the bracelet, while volunteers in the other block should use bug spray) does not control for potential confounding factors, as individuals in different blocks may have different levels of mosquito exposure.

Step-by-step explanation:

Given the function

f(x)=x^3+x^2+x

Get the inverse. Let y = f(x)

y = x^3+x^2+x

Replace y with x

x = y³+y²+y

Differentiate with respect to x

1 =3y²dy/dx + 2ydy/dx + dy/dx

1 = (3y²+2y+1)dy/dx

dy/dx = 1/3y²+2y+1

g'(x) = 1/3(g(x))²+2g(x)+1

If x = 3

g'(3) = 1/3(g(3))²+2g(3)+1

g'(3) =1/3(1)²+2(1)+1

g'(3) = 1/3+2+1

g'(3) = 1/6

The equation in spherical coordinates is:

\($\sin^2(\phi)\cos^2(\theta) + \sin^2(\phi)\sin^2(\theta) + \cos^2(\phi) = 1$\)

What is Equation in Spherical Coordinates?

A mathematical equation that is represented in terms of the spherical coordinates of a point is known as an equation in spherical coordinates. A three-dimensional coordinate system known as spherical coordinates makes use of two angles, typically represented by symbols and a radial distance (r), and a coordinate system to find points in space.

\($r^2 = 81$\)

To represent the equation in spherical coordinates, we substitute the Cartesian coordinates \($x = r\sin(\phi)\cos(\theta)$, $y = r\sin(\phi)\sin(\theta)$, and $z = r\cos(\phi)$\) into the equation. After substitution and simplification, we have:

\($r^2\sin^2(\phi)\cos^2(\theta) + r^2\sin^2(\phi)\sin^2(\theta) + r^2\cos^2(\phi) = 81$\)

Since \(r^2 = 81,\) we can substitute it into the equation:

\($81\sin^2(\phi)\cos^2(\theta) + 81\sin^2(\phi)\sin^2(\theta) + 81\cos^2(\phi) = 81$\)

Finally, we divide the equation by 81 to simplify:

\($\sin^2(\phi)\cos^2(\theta) + \sin^2(\phi)\sin^2(\theta) + \cos^2(\phi) = 1$\)

So, the equation in spherical coordinates is:

\($\sin^2(\phi)\cos^2(\theta) + \sin^2(\phi)\sin^2(\theta) + \cos^2(\phi) = 1$\)

n=9M, when m is 6,n=18

Step-by-step explanation:

If n is proportional to M

n=kM

27=3k

k=27/3

k=9

the formula on terms of n and M is

n= 9M

2) If m= 6,

n= 3M

n=3(6)

n=18

Answer:

n = 108

Step-by-step explanation:

given n is proportional to m² then the equation relating them is

n = km² ← k is the constant of proportion

to find k use the condition n = 27 when m = 3 , then

27 = k × 3² = 9k ( divide both sides by 9 )

3 = k

n = 3m² ← equation of proportion

when m = 6 , then

n = 3 × 6² = 3 × 36 = 108

Step-by-step explanation:

Answer:

A(4,8,12,16) is the answer

The area of the region is (3/4)ab.

Given: Let A and B be points in the plane. The region S is defined in the first quadrant consisting of those points such that ∆ABC is an acute triangle.

In a coordinate plane, let A be (0,a) and B be (b,0).

Let C be a point (x,y) in the first quadrant so that the ∆ABC is acute.

Then the slope of AB is  -a/b and the slope of AC is y/x.

The angle ∠BAC is acute if and only if -a/b . y/x < -1, i.e. ab > xy.

Since we want the region in the first quadrant consisting of those points such that ∆ABC is an acute triangle, we need to graph the set of all points in the first quadrant that satisfy the inequality ab > xy.

Area of the region S = area of first quadrant - area of shaded region

Area of first quadrant = a * b

Area of shaded region = (1/2) * b * a/2 = ba/4

Thus, the area of the region S is given by a*b - ba/4 = (3/4)ab

Therefore, the area of the region is (3/4)ab.
