Hi. I will help. Work is shown below.
x grapefruit = $4
y grapefruit = $12
How do we get from 4 to 12? We multiply by 3. Since we multiply by 3 on one side, we have to do the same to the other side, so 3 times x. That's 3x. Therefore, the answer is 3x.

Step-by-step explanation:
Robin dropped a lacrosse ball from a building. After each bounce the height of the ball is measured and recorded in the table. What is the height of the ball after bounce 7?
Answer:
2.5 cm
Step-by-step explanation:
From the first 4 bounces, we find that the height of the lacrosse ball after each bounce is 1/4 the height that it was after the previous bounce. Therefore, since the 7th bounce is 6 bounces after the first bounce, we can set up an equation to find the balls height (y), after some number of bounces after the first one:
[tex]y=10240*(\frac{1}{4})^x[/tex].
Plug-in 6 for x to get 2.5.
Hope this helps :)
How to solve these 3 problems
Answer:
a. decay; b. growth; c. decay; d. neitherr = 4; a = 1; y = 1·4^xa. an = 3(5^(n-1)); b. f(x) = (3/5)(5^x); c. exponential growth; d. y-intercept: 3/5; first term: 3.Step-by-step explanation:
There are two kinds of exponential problems here.
exponential functions of the form f(x) = a·b^xexponential sequences of the explicit form an = a1·r^(n-1)The second problem gives you a table that suggests the sequence form, but it asks for the exponential function form. The third problem does something similar.
__
1.In an exponential function of the form f(x) = a·b^x, the function grows if b>1 and decays if b<1. Using this check, we can easily answer ...
a. 0.4 < 1 . . . decay
b. 1.3 > 1 . . . growth
c. 1/2 < 1 . . . decay
d. 1 = 1 . . . neither growth nor decay; the function is constant: j(x) = 1.
__
2.The value of x is given starting at 1, so we can consider this a geometric sequence. The common ratio is r = 16/4 = 4. The first term is a1 = 4, so the explicit formula for the sequence is ...
an = 4·4^(n-1)
When this is expanded to get rid of the constant in the exponent, we have ...
an = 4·(4^n)·(4^-1) = 1·4^n
We recognize this form as matching the functional form f(x) = a·r^x. The multiplier of the exponential factor is a=1. In summary, ...
r = 4; a = 1; f(x) = 1·4^x
__
3.The first term of this geometric sequence is a1 = 3. The common ratio is r = 15/3 = 5. Using the explicit formula, we have ...
a. explicit form: an = 3·5^(n-1)
Using the method of question 2 to write the functional form, we find ...
an = 3(5^n)(5^-1) = (3/5)(5^n)
b. functional form: f(x) = (3/5)(5^x)
c. function family: exponential growth functions
d. y-intercept: (3/5) . . . . read this from the f(x) form
1st term: the first term listed in the given sequence is 3
_____
Additional comment
The "y-intercept" of a sequence is irrelevant (undefined), as the sequence term numbering starts with 1, not 0. The domain of the explicit formula is natural numbers, which does not include 0.
Similarly, the "first term" of a function f(x) needs further definition. Here, we've answered the question by saying the first term is f(1). There is no conventional definition of a "first term" for a continuous function.

Which expressions below equal an irrational number? Choose all that apply.
Answer:
see below
Step-by-step explanation:
An irrational number is a real number that cannot be written as a simple fraction. (Irrational means not rational).
0.2476931 + 12.4139 = 12.6615931 irrational
1/√3 x √3/√10 = √3 / √30 = √10 / 10 irrational
243/3 - 16/6 = 486/6 - 16/6 = 470/6 = 235/3 rational
∛21 x 3 = 8.276772529 irrational
(√9 + √6) - (4 - √6) = 3 +2√6 - 4 = -1 + 2√6 = irrational
Solve for x.
50 = x - (-14)
Answer:
x = 36
Step-by-step explanation:
Multiply the numbers
50 = x -1 (-14)
50 = x + 14
Subtract 14 from both sides of the equation
50 = x + 14
50 - 14 = x + 14 - 14
Simplify
x = 36

Answer:
x-intercept = (-8, 0)
y-intercept = (0, -2)
Step-by-step explanation:
Given linear equation is: x + 4y = - 8
For x - intercept: Plug y = 0 in the above equation.
[tex]\implies x +4(0) = -8\\\\\implies x +0 =-8\\\\ \implies x = -8\\\\ \boxed{\red{\bold{\implies x- intercept = (-8,\:0)}}}[/tex]

Anyone know how to figure this out?
Answer:
(a) f(x) = 110x -x^2
(b) $55
Step-by-step explanation:
(a)You figure out part (a) by following directions. Multiply (110 -x) by x. Use the distributive property to simplify it:
f(x) = 110x -x^2
__
(b)You know that the vertex of a parabola is on the line of symmetry, and that any two points with the same y-value are located symmetrically about that line. The function f(x) = x(110 -x) is zero for x=0 and for x=110. The vertex (maximum) of the function will be located halfway between these values, at ...
x = (0 +110)/2 = 55

a. x about 31/8
b. x about 29/8
c. x about 57/16
d. x about 61/16
Answer:
c. x about 57/16
Step-by-step explanation:
You have not specified the algorithm you use for one iteration. We will define it as follows:
The starting point is a pair of numbers that are upper and lower bounds on the solution. The iteration ends when a new value replaces one of these bounds. The final estimate of the root will be the average of the latest upper and lower bounds.
__
The given graph shows suitable initial bounds are 3 and 4. The sign of h(x) = f(x)-g(x) matches the sign of h(3) when x=7/2, so the value 7/2 will replace the lower bound at the end of iteration 1.
The new average of upper and lower bounds is (7/2 +4)/2 = 15/4. The sign of h(15/4) matches the sign of h(4), so 15/4 becomes the new upper bound at the end of iteration 2.
The new average of the bounds is (7/2 +15/4)/2 = 29/8. The sign of h(29/8) matches the sign of h(15/4), so 29/8 becomes the new upper bound at the end of iteration 3.
After 3 iterations, the bounds are 7/2 and 29/8. The average of these values is the approximate solution to the equation:
x = (7/2 +29/8)/2 = 57/16

We have tried to be clear about what we consider to be one iteration, and how a root approximation is arrived at. The definition of these things provided by your curriculum materials may be different.

Step-by-step explanation:
Bankruptcy make owning a car more expensive as It causes a loss of assets. Thus, option (A) is correct.
What is Bankruptcy?Bankruptcy refer to the situation in which individuals or other entities that are unable to pay their creditors back can seek partial or complete relief from their debts. Bankruptcy is typically imposed by a court order that is frequently requested by the debtor, and then legal process is undertaken.
In order to pay the expenses, the business owner has to sell their cars to decrease the amount of the debt. This kind of the situation arises at the time of the insolvency of the business and court also order starting the process of dissolution.
Therefore, it can be concluded that Since bankruptcy results in the loss of assets, having a car becomes more expensive. Hence, option (A) is correct.

Answer:
To simplify the ratio 5:9, we find the greatest common divisor of 5 and 9, and then we divide 5 and 9 by the greatest common divisor. Or if you want to know if its equivalent you would be able to divide evenly by the same number for both for example, 15:27 are equivalent since they both can be divided by themselves three times

Given that the area of a circle is [tex]\pi r^2[/tex], we have to plug in the value of the radius and simplify. The radius is half the diameter, which is a line that splits the circle into halves. Thus, the radius here is 3. 3^2 is 9, and we can shorten pi to 3.14. 3.14 x 9 is 28.26, so the area of the circle is 28.26 m^2.
