Does anybody know the answer?

Answer:

85.95

Step-by-step explanation:

If the local tax was 8% and we want to know what is was without the tax then we need to do 93.42 times .92

\(93.42*.92=85.9464\)

Since money only goes to the hundredths place we need to round there

\(85.95\)

Based on the amount that Adrian spent in total, the cost without taxes was $86.50.

The cost of the clothes was $93.42 including tax.

Assuming the original cost is x, the equation is:

Total cost = Original cost x ( 1 + tax)

Solving would give:

93.42 = x × (1 + 8%)

93.42 = 1.08x

x = 93.42 / 1.08

= $86.50

In conclusion, the cost without taxes was $86.50.

Relative frequency is the ratio of the number of outcomes in which a specified event occurs to the total number of trials.

In our problem, the specified event is 'deaths that occurred in 2003 or earlier' and the total number of trials is the total number of deaths from 2000 to 2012.

Adding up the deaths from 2000 to 2003, we get:

Then, the relative frequency is:

After rounding it, the answer is 0.08

Step-by-step explanation:

you have both points : (1, 1) and (5, 5).

so, we don't need to do any triangle calculations to get the height of the main triangle.

all we need to do is calculate the distance between these 2 points.

2 points in a coordinate grid create a right-angled triangle.

the direct distance is the Hypotenuse (the side opposite of the 90° angle). and the legs are the x- and the y-coordinate differences (one up or down the other left or right).

and we can use Pythagoras

c² = a² + b²

c being the Hypotenuse a and b being the legs.

so, how long are these legs here ?

the x-difference is 5 - 1 = 4.

also the y-difference is 5 - 1 = 4

so,

distance² = 4² + 4² = 16 + 16 = 32

distance = sqrt(32) = sqrt(16×2) = 4×sqrt(2) =

= 5.656854249...

the distance of P to the line RQ is 5.656854249...

Step-by-step explanation: I got a hundred on my test.

After the double rotation, the vertices of the quadrilateral MNPQ are transformed to M'', N'', P'', and Q''. The shape of the quadrilateral may have changed, but the order of the vertices remains the same.

When a quadrilateral MNPQ is rotated counterclockwise at 90 degrees about the origin, each vertex undergoes a transformation.

The new positions of the vertices after this rotation can be denoted as M', N', P', and Q'. The order of the vertices remains the same.

Next, when the rotated quadrilateral M'N'P'Q' is further rotated counterclockwise at 270 degrees about the origin, each vertex undergoes another transformation.

The new positions of the vertices after this rotation can be denoted as M'', N'', P'', and Q''. Again, the order of the vertices remains the same.

It's important to note that a 270-degree counterclockwise rotation is equivalent to a 90-degree clockwise rotation.

The result of the double rotation is equivalent to a single clockwise rotation of 90 degrees.

Based on the length of BC and AC, we can find the length of AB to be 112cm.

This is a right-angled triangle which means that we can use the Pythogorean theorem to solve for the length of AB which is the hypotenuse.

The length of AB is:

AB² = BC² + AC²

Solving gives:

AB² = 63² + 93²

AB² = 3,969 + 8,649

AB = √(12,618)

AB = 112 cm

A= 34

B= 112

C= 34

Step-by-step explanation:

A and C are vertical angles so would have the same angle degree. The 112 and B are same side interior angles so have the same degree

A and 112 are opposite interior angles so they have to add up to 180.

So 180-112=68

Answer:

a. The mean of the data set is:

(146 + 153 + 155 + 160 + 161) / 5 = 155

b. The deviation from the mean for each data item is:

146 - 155 = -9

153 - 155 = -2

155 - 155 = 0

160 - 155 = 5

161 - 155 = 6

c. The sum of the deviations from the mean is:

-9 + (-2) + 0 + 5 + 6 = 0

Note that the sum of the deviations from the mean is always zero, since the positive deviations cancel out the negative deviations.

Direct distance from the base of the Space Needle to Kasie's house = 1429 feet.

The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line. It is basically used to get the distance of the two objects where the angles and an object's distance from the ground are known to us.

Given,

Height of the observation deck AB = 520 feet

Angle of depression = 70°

Distance of the Space needle base to house BC = ?

By the figure,

tan70° = AB/BC

BC = tan70°(AB)

BC = 2.7475(520)

BC = 1428.7 feet

Distance of the Space needle base to house to nearest foot = 1429 feet

Hence, 1429 feet is the distance between base of the Space Needle to Kasie's house.

For the given function, the critical point is (-1,2), relative extrema is is 2, and saddle points is zero.

To find the critical points of a function, we need to find where the partial derivatives of the function are equal to zero or do not exist. In other words, we need to find the points where the function is not changing with respect to x and y. The partial derivative of f(x,y) with respect to x is:

fx = 2x + 2

And the partial derivative of f(x,y) with respect to y is:

fy = 2y - 4

To find the critical points, we set both partial derivatives to zero and solve for x and y:

fx = 2x + 2 = 0

=> x = -1

fy = 2y - 4 = 0

=> y = 2

So, the critical point of the function is (-1, 2).

To determine whether this critical point is a relative maximum, minimum, or saddle point, we need to look at the second partial derivatives of the function. The second partial derivative of f(x,y) with respect to x is:

fx = 2

And the second partial derivative of f(x,y) with respect to y is:

fy = 2

The mixed partial derivative of f(x,y) with respect to x and y is:

fy = 0

To classify the critical point, we can use the second derivative test.

If fx and fy are both positive (or both negative) at the critical point, then the critical point is a relative minimum (or maximum), respectively.

If fx and fy have different signs, then the critical point is a saddle point. If the second derivative test is inconclusive, then we need to use additional methods to determine the nature of the critical point.

The limit of the difference quotients for f(x) = x^2 + 2x + 1 as x approaches -1 is indeterminate.

To find the limit of the difference quotients for the function f(x) = x^2 + 2x + 1 as x approaches -1, we need to evaluate the following expression:

lim(x→-1) [f(x) - f(-1)] / (x - (-1))

First, let's substitute the values into the expression:

lim(x→-1) \([(x^2 + 2x + 1) - (-1^2 + 2(-1) + 1)] / (x + 1)\)

Simplifying further:

lim(x→-1) \([(x^2 + 2x + 1) - (1 - 2 + 1)] / (x + 1)\)

lim(x→-1)\([x^2 + 2x + 1 - 0] / (x + 1)\)

lim(x→-1) \((x^2 + 2x + 1) / (x + 1)\)

Now, we can directly substitute x = -1 into the expression:

\((-1^2 + 2(-1) + 1) / (-1 + 1)\)

(1 - 2 + 1) / (0)

0 / 0

We have obtained an indeterminate form of 0/0. This indicates that we need to further simplify the expression or use other techniques, such as L'Hôpital's rule, to evaluate the limit. However, without additional information or simplification, we cannot determine the precise value of the limit at x = -1.
