Which statement about the graph of this function is true?
Answer:B
Step-by-step explanation:
The exponential curve passes through the point (0, 70). Then the correct option is B.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
The table addresses a few focuses on the diagram of the outstanding capability that models the radioactive rot of an example of xenon-135.
At x = 4.6, the value of 'y' will be 49.5.
[tex]\rm 49.5 = ab^{4.6} \ \ \ \ \ \ \ ...1\\[/tex]
At x = 9.2, the value of 'y' will be 35.
[tex]\rm 35= ab^{9.2} \ \ \ \ \ \ \ ...2[/tex]
From equations 1 and 2, then we have
[tex]\rm \dfrac{b^{9.2}}{b^{4.6}} = \dfrac{35}{49.5}\\\\b^{4.6} = 0.707\\\\b = 0.927\\[/tex]
Then the value of 'a' will be
[tex]\rm 49.5 = a (0.927)^{4.6}\\\\a = 70[/tex]
Then the equation is given as,
y = 70 · (0.927)ˣ
The graph is given below.
The exponential curve passes through the point (0, 70). Then the correct option is B.

what is the answer to 2(3x-5) = 4x+2? Well not the answer but like the steps to solving it
Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(3x−5)=4x+2
(2)(3x)+(2)(−5)=4x+2(Distribute)
6x+−10=4x+2
6x−10=4x+2
Step 2: Subtract 4x from both sides.
6x−10−4x=4x+2−4x
2x−10=2
Step 3: Add 10 to both sides.
2x−10+10=2+10
2x=12
Step 4: Divide both sides by 2.
2x=12
x=6

A submarine is at an elevation of -100 feet (100 feet below sea level). Let’s compare the elevations of these four people to that of the submarine:
Clare’s elevation is greater than the elevation of the submarine. Clare is farther from sea level than the submarine.
Andre’s elevation is less than the elevation of the submarine. Andre is farther away from sea level than the submarine.
Han’s elevation is greater than the elevation of the submarine. Han is closer to sea level than is the submarine.
Lin’s elevation is the same distance away from sea level as the submarine’s.
1. Complete the table as follows.
Write a possible elevation for each person.
Use <, >, or = to compare the elevation of that person to that of the submarine.
Use absolute value to tell how far away the person is from sea level (elevation 0).
As an example, the first row has been filled with a possible elevation for Clare.
Andre : Anything less than -100, for example -150
-150<-100
|-150|=150
Han: Anything between -100 & 100, for example 50
50> 100
|50|= 50
Lin: 100 or -100,
100> -100
|100|=100
or
-100=-100
|-100|=100

k=+8.75
Step-by-step explanation:
For each increase in time (one hour increase), the amount increased by $8.75.
example:
1 = 8.75
2 = 17.50
3 = 26.25
4 = 35.00
5 = 43.75
6 = 52.50
7 = 61.25
8 = 70.00
9 = 78.75
10 = 87.50
The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the
exponential equation?
Sorry for tje late answer but it is 150 * 0.08^x
The exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].
What is depreciation?Depreciation is the rate by which the value of an object reduces with respect to time. it is given by the formula,
[tex]A = P(1-\dfrac{r}{100})^t[/tex]
where A is the value of object after t period of time, P is the principal amount, r is the rate of depreciation, and t is the time period.
We know the formula of the depreciation, Also, the initial value of the car is $15,000, and the rate of depreciation r that is 8% per year. Therefore, the function of the depreciation of the car can be written as,
[tex]A = P(1-\dfrac{r}{100})^t\\\\A = 15000(1-\dfrac{8}{100})^t\\\\A = 15000(1.08)^t[/tex]
Hence, the exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].

Find the distance between the two points in simplest radical form. Pleasee answer correctly !!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
[tex]\boxed{\textsf{ The distance between the two points is \textbf{12.164 units }.}}[/tex]
Step-by-step explanation:
Two points are given to us and we need to find the distance in simplest radical form. The given two points are (3,9) & (-2,2) . So lets use Distance Formula to find the distance between them .
Distance Formula is :-
[tex]\sf\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}\\\\\sf\implies Distance =\sqrt{ (-2-3)^2+(9-2)^2}\\\\\sf\implies Distance =\sqrt{ -5^2+7^2}\\\\\sf\implies Distance = \sqrt{ 25 + 49} \\\\\sf\implies Distance = \sqrt{ 74} \\\\\sf\implies Distance=\sqrt{37}\times 2\\\\\sf\implies \boxed{\pink{\sf Distance = 12.164 units .}}[/tex]

Answer:
A: Any positive value
Step-by-step explanation:
Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.
Answer:
A: Any Postive value or B: No Solution
Step-by-step explanation:
Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.
