Answer:
Option D. is the correct answer.
The function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50
Step-by-step explanation:
From the question,
Lisa is saving $50 that she received from her grandmother,
Also, she earns $6 each time she walks her neighbor's dog, which she also saves.
Now, to determine the function that can be used to find the amount of money Lisa will have saved after walking the neighbor's dog d times, we will determine how much she will earn from walking the dog d times and then add it to the money she received from her grandmother. \
If she earns $6 each time she walks her neighbor's dog, then
she will earn $6×d if she walks the neighbor dog for d times.
$6 × d = $6d
Hence, she will earn $6d from walking the dog d times.
The total amount she will have saved will be $6d + $50.
Hence, the function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50.
Option D. is the correct answer.

Consider the Graph. a. Determine four lines of symmetry for the graph. b. How many other lines of symmetry does this graph possess? c. What other type of symmetry does this graph posses
Answer:
Step-by-step explanation:
a). Lines of symmetry of the circle given in the picture are,
x = 0
y = 0
y = -x
y = x
b). Since, a circle has infinite lines of symmetry (diameters) so the other lines of symmetry of the given circle will be all infinite numbers of the diameters.
c). Other symmetry this circle has a point symmetry.

Flora Kenyon made a deposit of $1,600 to her savings account on July 1. For the next year she made no other deposits or withdrawals. Her bank pays an annual interest of 3.1% compounded quarterly. Find the interest earned by Flora by July 1 of the next year.
Answer:
A = $1,650.24
Step-by-step explanation:
A = P(1 + r/n)^nt
Where
A = future value
P = present value = $1,600
r = interest rate = 3.1% = 0.031
n = number of periods = 4
t = time = 1 year
A = P(1 + r/n)^nt
= 1,600( 1 + 0.031 / 4)^4*1
= 1600( 1 + 0.00775)^4
= 1600(1.00775)^4
= 1600(1.0314)
= 1,650.24
A = $1,650.24

what is the rate of change in y= 2x+3
Answer:
The Answer is 2
EXPLANATION:
y(x)=2x+3
y(x+Δx)=2(x+Δx)+3
=2x+2Δx+3
Δy=y(x+Δx)−y(x)
=(2x+2Δx+3)−(2x+3)
=2Δx
⇒Δy=2Δx, Δy/Δx =2
The rate of change in the equation of a line in slope-intercept form
y = 2x + 3 is 2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An equation of a line y = 2x + 3.
This is in slope-intercept y = mx + b, where 'm' is the slope.
Therefore, The rate of change in y = 2x + 3 is 2.

I can travel 612 miles in 1 hour in my super speedy plane. Assume that there are 5,280 ft per mile. How many feet would I travel in 1 minute?
Answer:
53856 feet
Step-by-step explanation:
612*5280 represents how much you would travel in an hour. Then divide the product by 60 to get per minute. 612*5280=3231360ft per hour. 3231360/60=53856 feet per minute. Happy to help!

Larry recorded his time as he ran. What was his average speed from hour 2 to hour 4?
What was his average speed from hour 4 to hour 7?
Did he speed up or slow down?
Answer:
7mph and he stayed the same
Step-by-step explanation:
Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same, 7 mi/hr, he maintained a constant speed throughout this period.
Given that Larry recorded his time as he ran
Time elapsed(hr) Distance run(mi)
2 13.5
4 27.5
7 48.5
We need to calculate his average speed,
To calculate Larry's average speed, we need to divide the total distance he ran by the time elapsed.
Let's calculate his average speed from hour 2 to hour 4 and from hour 4 to hour 7:
Average speed from hour 2 to hour 4:
Distance covered = 27.5 mi - 13.5 mi = 14 mi
Time elapsed = 4 hr - 2 hr = 2 hr
Average speed = Distance covered / Time elapsed = 14 mi / 2 hr = 7 mi/hr
Therefore, Larry's average speed from hour 2 to hour 4 was 7 miles per hour.
Average speed from hour 4 to hour 7:
Distance covered = 48.5 mi - 27.5 mi = 21 mi
Time elapsed = 7 hr - 4 hr = 3 hr
Average speed = Distance covered / Time elapsed = 21 mi / 3 hr = 7 mi/hr
Therefore, Larry's average speed from hour 4 to hour 7 was also 7 miles per hour.
Since Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same (7 mi/hr), he maintained a constant speed throughout this period. He neither sped up nor slowed down.

Is there anyone good at algebra 2 to solve this problem? I need help with part c.
Answer:
40 ft
Step-by-step explanation:
The maximum height of the ball is the y- coordinate of the vertex
Given a parabola in standard form then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
h(t) = - 16t² + 48t + 4 ← is in standard form
with a = - 16, b = 48 , thus
[tex]x_{vertex}[/tex] = - [tex]\frac{48}{-32}[/tex] = 1.5
Substitute t = 1.5 into h(t) for max. height
h(1.5) = - 16(1.5)² + 48(1.5) + 4
= - 36 + 72 + 4
= 40
