\((f +g)(10) = 108\)

Before we can solve for \((f +g)(10)\), we need to know how \((f +g)(x)\) is defined.

\((f +g)(x) = f(x) +g(x) \\ (f +g)(x) = (x^2 -1) +(x -1) \\ (f +g)(x) = x^2 -1 +x -1 \\ (f +g)(x) = x^2 +x -2\)

We can now solve for \((f +g)(10)\):

\((f +g)(10) = (10)^2 +(10) -2 \\ (f +g)(10) = 100 +10 -2 \\ (f +g)(10) = 108\)

Answer: C

Step-by-step explanation:

Point D is at -14 on the number line.

In Mathematics, the midpoint of a line segment with two end points can be calculated by adding each end point on a line segment together and then divide by two (2).

Since E is the midpoint of line segment CD, we can logically deduce the following relationship:

Line segment CD = Line segment C + Line segment D

Midpoint E = (point C + point D)/2

By substituting the given points into the equation above, we have the following:

-3 = (8 + D)/2

-6 = 8 + D

D = -6 - 8

D = -14

Distance from the origin to the points  ≈ 0.41.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]  

Point A (5, 3, 4) and point B (−4, 2, 6) are located away from the origin (0,0,0), and the points from the origin to this points are expressed as OB - OA where;

Let OB is the distance from the origin to the point B

Let OA is the distance from the origin to the point A

Using the formula for calculating the distance between two points;

OA = √(z2-z1)²+(y2-y1)²+(x2-x1)²

OA = √(4-0)²+(3-0)²+(5-0)²

OA = √(16)+(9)+(25)

OA = √50

OA = 7.071

Similarly;

OB = √(6-0)²+(2-0)²+(-4-0)²

OB = √(6)²+(2)²+(-4)²

OB = √36+4+16

OB = √56

OB = 7.4833

Distance from the origin to the points = 7.4833 - 7.071= 0.4123

Solution:

Let x = number of cupcakes and y = number of cookies

The objective is to maximize revenue, which is given by the equation:

Revenue = 2x + 1.5y

The constraints are:

0.5x + 0.3y ≤ 150 (budget)

x + y ≤ 300 (maximum number of baked goods)

x ≥ 0, y ≥ 0 (non-negativity)

Using the simplex method, the optimal solution is x = 200 and y = 100. This means that 200 cupcakes and 100 cookies should be baked in order to maximize the revenue given the constraints.

Step-by-step explanation:

To find how much Josephine earned, we multiply the commission percentage by the amount Josephine sold and adds it to the amount she earns per week:

Total salary/week = salary/week + commission amount * worth of goods

Letting Ts represent the total salary per week, we have

\(Ts=560+0.10*843\\Ts=560+84.3\\Ts=644.30\)

a.Linear

b. Non-linear

1) Let's calculate these differences so that we can tell whether these are linear or non-linear functions from these tables

2) So, setting the tables we've got:

a)

x | y First Differences

-2| -5 -5 - (-2) = -5 +2 = -3

-1| -2 -2 - 1 = -3

0| 1 1-4 = -3

1| 4

Since the first differences yield the same result, -3 then we can tell this is a Linear Relation.

b) Examining the second table we've got

x| y First Difference

4 5 5-2 =3

6 2 2-1 = 1

8 1

The perimeter of a polygon is given by the sum of all the lengths of the outer edges of the figure, that is, we must find the length of all the edges of the polygon, and then add these lengths to obtain the perimeter.

The diagonal length can be obtained as follows:

RU + UT = 7.

Applying the Pythagorean Theorem, the side length is obtained as follows:

x² + x² = 7²

2x² = 49

\(x = \sqrt{\frac{49}{2}}\)

x = 4.95.

Then the perimeter is given as follows:

Assess reasonableness a monument will be at the circumcenter of a triangular plot of land at the state capital. on the coordinate grid, the vertices of the triangular plot of land are a(1, 5) , b(7, 5) , and c(8, 0) .

Overall, the statement that Unsupervised learning has more models and more evaluation methods used in order to ensure the outcome of the model is accurate is false. Unsupervised learning algorithms are taught using data that may be labeled, but in most cases the labels are not used to infer the model. The model of unsupervised learning does not take any feedback, as it is not supervised, and only input data is supplied to the model, no output data. The evaluation of unsupervised learning models relies on different metrics such as clustering accuracy, silhouette coefficient, etc. Unsupervised learning algorithms are used for tasks such as clustering, anomaly detection and density estimation.

Answer

The distance from the origin to point P = 10 units

Explanation

The distance between two points with the coordinates (x₁, y₁) and (x₂, y₂) is given as

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Noting tha the origin is (0, 0), for this question,

(x₁, y₁) and (x₂, y₂) is (-8, 6) and (0, 0) respectively

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(0 - -8)² + (0 - 6)²]

d = √[8² + (-6)²]

d = √(64 + 36)

An equation that shows how to find the pounds of seed, p, needed for h hectares of land is p = 20h.

An equation that shows how many hectares, h, Harper can plant with p pounds of seed is h = p/20.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this table;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (300 - 200)/(15 - 10)

Slope (m) = 100/5

Slope (m) = 20

At data point (10, 200) and a slope of 20, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 200 = 20(x - 10)  

y = 20x - 200 + 200

y = 20x ≡ p = 20h

Making h the subject of formula, we have:

Answer:

simple interest=$97.50.

compound interest= $100.668

Step-by-step explanation:

Given:

Principal (P) = $750

Rate (R) = 6.5% (in decimal form, 0.065)

Time (T) = 2 years

Simple Interest = Principal*Rate*Time

Using the formula, the simple interest is calculated as follows:

Simple Interest = $750*0.065*2 = $97.50

Therefore, the simple interest for $750 with a 6.5% interest rate over 2 years is $97.50.

Again:

Compound Interest = Principal*(1 + Rate)^(Time)-Principal

Using the same values as above, the compound interest can be calculated as follows:

Compound Interest = $750*(1+0.065)^(2)-$750

= $750*1.065^2 -$750

= $750 × 1.134225 - $750

= $850.66875-$750

= $100.668

Therefore, the compound interest for $750 with a 6.5% interest rate over 2 years is $100.668
