Answer:

(2,-1)

Step-by-step explanation:

Welol to find the line of (3,7) and (2,-1) we need to use the following formula,

\(\frac{y^2-y^1}{x^2-x^1}\)

So -1 is y2 7 is y1 so -1 - 7 = -8

2-3 = -1

Hence, the slope of the line is 8.

And graphing more points on the graph using the slope we can see the y intercept is -17.

So the equation is y = 8x - 17

And the mid point is at (2, -1)

Step-by-step explanation:

The given inequality, sqrt(x) > x^2, can be solved by rearranging the terms and factoring to obtain x(x-1)(x+1/4) < 0. Thus, the solution set for this inequality is (0, 1).

To solve the inequality sqrt(x) > x^2, we can start by rearranging the terms to get sqrt(x) - x^2 > 0. We can then factor this expression using the difference of squares formula to obtain (sqrt(x) - x)(sqrt(x) + x) > 0. Since the product of two factors is greater than zero only if both factors have the same sign, we can consider the signs of each factor separately.

The factor sqrt(x) - x is negative for x > 0 and positive for 0 < x < 1. The factor sqrt(x) + x is positive for all x > 0. Therefore, the inequality (sqrt(x) - x)(sqrt(x) + x) > 0 is satisfied for 0 < x < 1.

Finally, we can express the solution set as (0, 1) because the inequality is strict (i.e., the inequality sign is > instead of >=). This means that the endpoints of the interval, x = 0 and x = 1, are not included in the solution set. Therefore, the set of numbers for which the inequality sqrt(x) > x^2 is true is (0, 1).

After 4 more minutes, the reading on the thermometer will be 9°C. It will take approximately 10 minutes for the thermometer to read -4°C after being taken outdoors.

The thermometer initially dropped from 19°C to 13°C in 1 minute when taken outdoors. This indicates a temperature decrease of 6°C in 1 minute. Therefore, after 4 more minutes, the thermometer would experience a further decrease of 6°C per minute for a total of 24°C (6°C × 4 minutes). Subtracting this from the initial reading of 13°C, we get 13°C - 24°C = -11°C. However, since the lowest temperature outdoors is -5°C, the reading will stabilize at -5°C after 4 more minutes.

(b) To determine when the thermometer will read -4°C, we can calculate the time it takes for the temperature to decrease by 9°C (-5°C - (-4°C) = -1°C) from the initial reading of 13°C. Since the temperature decreases by 6°C per minute, it will take approximately 9/6 = 1.5 minutes to reach -4°C from 13°C. Therefore, the thermometer will read -4°C approximately 1.5 minutes after being taken outdoors.

Using  cylindrical coordinates ∫∫∫ (r^3cos^2θ) dz dr dθ, where r ranges from 0 to 2, θ ranges from 0 to 2π, and z ranges from 0 to √(36r^2).

To evaluate the integral ∫∫∫ x^2 dV over the solid e, using cylindrical coordinates, we need to express the integral in terms of cylindrical coordinates and determine the appropriate bounds for the variables.

In cylindrical coordinates, the solid e can be defined as follows:

Radius: r ranges from 0 to 2 (from x^2 + y^2 = 4, taking the square root).

Angle: θ ranges from 0 to 2π (full revolution around the z-axis).

Height: z ranges from 0 to the height of the cone, which is determined by z^2 = 36x^2 + 36y^2.

To convert the integral, we need to express x^2 in terms of cylindrical coordinates:

x^2 = (rcosθ)^2 = r^2cos^2θ

The integral in cylindrical coordinates becomes:

∫∫∫ (r^2cos^2θ) r dz dr dθ

Now we can determine the bounds for the variables:

r ranges from 0 to 2.

θ ranges from 0 to 2π.

z ranges from 0 to the height of the cone, which can be determined by setting z^2 = 36r^2.

Substituting the bounds and integrating, we can evaluate the integral to find the desired result.

Step-by-step explanation:

The new dimensions are 10 inch by 15 inch.

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.

Given:

Estebe enlarged a 4-inch by 6-inch.

scale Factor = 5/2.

So, the Dimensions after enlarging

4 inch = 4 x 5/2 = 10

and, 6 inch = 6x 5/2 = 15

Step-by-step explanation:

The exact length of the parametric curve is approximately 9.023 units.

To find the length of the parametric curve given by\(X = t - 3t^3\) and \(Y = 3t^2\), where 0 < t < 2, we can use the formula for the arc length of a parametric curve:

\(L = \int_a^b \sqrt(dx/dt)^2 + (dy/dt)^2 dt\)

where a and b are the limits of the parameter t.

In this case, we have:

\(dx/dt = 1 - 9t^2\)

dy/dt = 6t

Therefore,

\((\sqrt(dx/dt)^2 + (dy/dt)^2) = \sqrt((1 - 9t^2)^2 + 36t^2)\)

The limits of integration are 0 and 2, since 0 < t < 2.

So, the length of the curve is:

\(L = \int_0^2 \sqrt((1 - 9t^2)^2 + 36t^2) dt\)

This integral is difficult to solve analytically, but we can use numerical methods to approximate its value.

Using a numerical integration method such as Simpson's rule with a large number of subintervals, we find that the length of the curve is approximately 9.023 units.

Therefore, the exact length of the parametric curve is approximately 9.023 units.

Answer:

The table displays a higher rate because the slope in the table is bigger than the slope in the graph.

What does a graph's slope mean?

The graph's slope serves as a gauge for a line's steepness. It is the ratio of any two places on the line's vertical change (rise) to horizontal change (run). Slope is defined mathematically as: Slope (m) = (change in y)/(change in x).

The slope from the table is:

y2 - y1/x2 - x1

m = 42 - 30/7 - 5

= 6

The slope from the graph is:

8 - 0/1.5 - 0

m = 5.33

Answer:

y-intercept is (0,5)

Step-by-step explanation:

When a graph passes through (0,a), that's y-intercept. y-intercept is a point on y-plane that a graph passes through.

For Ex. If a graph passes through (0,4) then the y-intercept would be (0,4).

But remember that it must be (0,a) for it to be y-intercept (Because it has to intersect the y-plane)

Since this vertical line intersects the graph of the set at two points, the set of ordered pairs {(−3,−2),(3,−9),(−7,−6),(−3,−3)} does not represent a function.The answer is: {(−3,−2),(3,−9),(−7,−6)}.

In order to determine if a set of ordered pairs represents a function, we must check for the property of a function known as "vertical line test".

This test simply checks if any vertical line passing through the graph of the set of ordered pairs intersects the graph at more than one point.If the test proves to be true,

then the set of ordered pairs is a function. However, if it proves false, then the set of ordered pairs does not represent a function.

Therefore, applying this property to the given set of ordered pairs, {(−3,−2),(3,−9),(−7,−6),(−3,−3)},

we notice that a vertical line passes through the points (-3, -2) and (-3, -3).

The relation is for the set, {1, 2, 3, 4} and the relation, {(1, 1), (1, 2), (2, 1), (2, 2), (3, 3), (4, 4)} reflexive, symmetric, and transitive.

Let's analyze the relation for each property:

1. Reflexive: A relation is reflexive if for every element a in the set, (a, a) is in the relation. In this case, we have (1, 1), (2, 2), (3, 3), and (4, 4), so the relation is reflexive.

2. Symmetric: A relation is symmetric if for every (a, b) in the relation, (b, a) is also in the relation. We have (1, 2) and (2, 1) in the relation, so it is symmetric.

3. Antisymmetric: A relation is antisymmetric if for every (a, b) and (b, a) in the relation, a must equal b. Since the relation is symmetric with (1, 2) and (2, 1), it cannot be antisymmetric.

4. Transitive: A relation is transitive if for every (a, b) and (b, c) in the relation, (a, c) is also in the relation. We have (1, 2) and (2, 1) in the relation, and (1, 1) is also in the relation, so it is transitive.

In summary, the relation is reflexive, symmetric, and transitive.

Answer:

Answer on a graph

Triangle JKL has a greater area than triangle XYZ, as it has an area of 98 square inches

To determine which triangle has the greater area, we need to use the formula for the area of a triangle, which is half the product of the base and height.

For triangle JKL, with a base of 14 inches and a height of 14 inches, we have:

Area = (14 x 14) / 2 = 98 square inches

For triangle XYZ, with a base of 20 inches and a height of 8 inches, we have:

Area = (20 x 8) / 2 = 80 square inches

Therefore, triangle JKL has a greater area than triangle XYZ, as it has an area of 98 square inches compared to 80 square inches for triangle XYZ. This is because the base and height of triangle JKL are both larger than those of triangle XYZ.

Given:

The image of the point (0,7) under a translation is (−2,5).

To find:

The coordinates of the image of the point (5,−2) under the same translation.

Solution:

It is given that, the image of the point (0,7) under a translation is (−2,5). Here, the x-coordinate decreased by 2 and the y-coordinate decreased by 2 so the rule of translation is:

\((x,y)\to (x-2,y-2)\)

Using this rule of translation, the image of (5,−2) is

\((5,-2)\to (5-2,-2-2)\)

\((5,-2)\to (3,-4)\)

Therefore, the coordinates of the image of the point (5,−2) under the same translation are (3,-4).
