the formula for a function of the form y= a е⁻ˣ +b x with global minimum at (1,10)  is  y= 5е¹ ⁻ ˣ +5 x

We can use first and second derivative tests to determine all coefficients of the function described in statement so that the point given is an absolute minimum. The expressions for such tests are introduced below:

First Derivative Test

-a .е⁻ˣ +b = 0   (1)

b=a .е⁻ˣ

Second Derivative Test

y''= a . .е⁻ˣ  (2)

Where y'' >0

If we know that ( x,y) = 9 1,10) , then we have the following system:

b= a е⁻¹  (4)

y'' = a е⁻¹  (5)

By (4) in (3):

The equation of the line parallel to the given line that contains C is obtained as y = x + 6.

For the given question;

The equation of the line is given as;

y = x + 4

The standard form of the equation of line in slope intercept form is;

y = m x + c

where, m is the slope and c is the y intercept.

On comparing;

m₁ = 1

Now, the other lien is parallel to the given line.

Thus, slopes of both lines will be equal.

m₁ = m₂ = 1

The passing points of the line are;

(x₁, y₁) = C(1, 7)

Now, the equation of lien will be;

y - y₁ = m₂(x - x₁)

Put the values;

y - 7 = 1(x - 1)

Simplifying.

y = x + 6

Thus, the equation of the line parallel to the given line that contains C is obtained as y = x + 6.

Answer:

x = 6 cm

Step-by-step explanation:

The two shapes are similar. That means one figure is exactly a multiple of the other figure

We can see that the ration of the length of the bigger rectangle  to the length of the smaller rectangle is 15/9 = 5/3  

Therefore the ratio of the width of the bigger rectangle  to the width of the smaller rectangle must also be 5/3

Given width of big rectangle = 10 and that of small rectangle is x

We get

10/x = 5/3

Multiply by x both sides:
x ×   10/x   =   x × 5/3

10 = 5x/3

Multiply by 3 both sides

30 = 5x

5x = 30

Dividing by 5 both sides
5x/x = 30/5
x = 6 cm

The number line that correctly compares √24 and 4.256 is number line C.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used for the comparison of two or more numbers such as √24 and 4.256. Also, a number line typically decreases in numerical value towards the left and increases in numerical value towards the right.

Taking the square root of √24, we have:

√24 = 4.899

In this context, we can reasonably and logically deduce that 4.899 is greater than 4.256 (4.899 > 4.256) and would be placed at the right hand side of the number line and further from 4.899 as shown in number line C in the image attached below.

The correct answer is that y does not vary directly with x.

If y and x are directly related, then the equation y=kx would be true for each point in the set.

What is the explanation:

If y is directly related to x, then every point in the set would fit the equation y=kx.

For the first point, we would have 11=7k, which would imply that k=11/7.

For the second point, we would have 13=8k, which would imply that k=13/8.

By utilizing proportions to check, we can see that 11/7 does not equal 13/8.

Cross multiplying yields 11*8=7*13, or 88=91

Since this is untrue, k is not a constant and y does not change in accordance with x.

Given the depth on the first day is 26 ½ feet.

Depth on the second day = 9½ feet more than on the first day i.e. 9½ feet + depth on the first day

This implies, depth on the second day = 9½ + 26 ½

The relationship between translations, reflections, and rigid motion is that they are all types of rigid motions, which means their size does not change.

Rigid motion is the movement of a set in which the distance between points remains constant.

Translation is a type of rigid motion in which an object simply slides while maintaining its direction.

A reflection, like a mirror, causes an image to flip to another location.

We must establish a connection between translations, reflections, and rigid motion.

We can conclude from the above definitions that the size of the object remains constant, but it is undergoing different transitions.

Therefore, Translations, reflections, and rigid motion all belong to the category of transformations that are rigid motions, which means that their sizes don't change.

The function which has a graph with the largest positive x-intercept is C. f(x) = 2(x-8) +1

The value of the x coordinate at the point where the graph crosses the x-axis is known as the x-intercept for any curve. Alternatively, we can say that the x-intercept is the value of the x coordinate at the point where the value of the y coordinate equals zero.

Let y be 0, so lets find the x-intercept of

A. 2(x+5)-1 = 0                                    

⇒ 2(x+5) = 1

⇒ 2x + 10  = 1

⇒ 2x  = -9

⇒ x = -9/2

B. 8(x+8) = 0

⇒ x+8 = 0

⇒ x = 0 −8

⇒ x = −8

C.  2(x-8) +1 = 0

⇒ 2x − 15 = 0

⇒ 2x = 15

⇒ x = 15/2

⇒ x = 7.5

Answer:

Step-by-step explanation:

Answer: No, this is not a function.

Functions exist when there are a unique set of x-values and each can match with a y-value. There cannot be a repeating x-value because this creates a discontinuity in the graph. You can have as many repeating y-values as you’d like as long as they each have a unique x-value and are not duplicate plot points.

Since x = 7 repeats in the domain of x-values, this cannot be a function.

Explanation:

The given translation rule is (x, y) → (x+8, y - 3) which says "shift 8 units right and 3 units down".

The inverse transformation will undo each to get "8 units left and 3 units up"

So the inverse is (x, y) → (x-8, y + 3)

Use this inverse to determine the preimage of point T'(2,-6)

[tex](\text{x},\text{y})\to(\text{x}-8,\text{y}+3)\\\\(2,-6)\to(2-8,-6+3)\\\\(2,-6)\to(-6,-3)\\\\[/tex]

Therefore, preimage point T is located at (-6,-3) which points us to answer choice B

If we were to apply the rule of "shift 8 units right and 3 units down" to T(-6,-3), you should arrive at T'(2,-6)
