Answer: f(x) = 64 * (3/4)^x
Step-by-step explanation: f(x)=ab^x
When x=0 f(x) = 64
64 = ab^0
b^0 =1 so
64 =a
f(x)=64 b^x
When x=1 f(x) = 48
48 = 64 *b
Divide by 64
48/64 =b
6/8 =b
3/4 =b
f(x) = 64 * (3/4)^x

A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.
Write the equivalent expression ("simplified") that represents the total volume of the water in the pool in ft3.
Answer:
The total volume of water in the pool = ( 6x^3 + 12x^2 - 90x ) ft^3
Step-by-step explanation:
The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3
The volume of water in the shallow = (4x^3 -100x) ft^3
The total volume of water in the pool = (2x^3 + 12x2 + 10x) + 4x^3 -100x)
= ( 6x^3 + 12x^2 - 90x ) ft^3

What is the solution
Please help
Answer:
Step-by-step explanation:
1.)
3x=3
x=1
2+y=0
y=-2
solution: (1,-2)
2.)
6y = -36
y = -6
-4x+12 = -12
-4x=-24
x = 6
solution: (6,-6)
Answer:
Top: x=1, y= -2
Bottom: x= 6, y= -6
Step-by-step explanation:
Top:
Isolate x for y: 2(3+y) + y = 0
Simplify: 6+3y=0
Isolate y for 6+3y=0: y = -2
For x= 3 + y: x = 1
Bottom:
Isolate x for : -4x - 2y= -12: x= [tex]\frac{-6 + y}{2}[/tex]
Simplify: 6y+ 12 = -24
Isolate y for 6y+ 12 = -24: y = -6
For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6
Fill in the blanks
[tex]1. (-2) x (-4.5)
2. (-8.7) x (-10)
3. (-7) x ? = 14
4. ? x (-10) = 90[/tex]

The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.
What is mean absolute deviation?It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.
We have data as shown in the picture in the form of frequency graph.
The mean = 11/4 = 2.75
The difference between each value and mean is shown in the attached table.
MAD = 5/4 = 1.25
The nearest value is 1.1.
Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?
Answer:
5625 feet
I hope it's helps you
Answer:
5625 feets
Step-by-step explanation:
Rate(feet/seconds) = height(feets)/time(seconds)
175 = x/25
x = 4375
After the skydiver opens his parachute the height reduces
Initial height – reduced height
10000 – 4375
= 5625 feets
Can someone please help me with this question the instructions are to use a calculator to find the perimeter (the solid lines and curves) of each figure. The perimeter of each semicircle can be found by using the equation 1/2 pi d (the place where I put the words pi has the pi symbol, and d is just a variable.

Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.
Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.
Answer:
The representation of Brian's situation in slope intercept form is:
y= 15x +70
Step-by-step explanation:
Let x be the number of weeks Brian started his collection.
y be the number of cards Brian has at present.
y= 45+25+ 15 x
or, y= 15 x +70
which is in the form of,
y= mx +c (slope intercept form)
where,
m= slope
x= x- intercept
c= constant.

Answer:
53.12ft
Step-by-step explanation:
Area of triangle:
The formula to find the area of a triangle is 1/2bh
- We plug in the values given.
1/2 x 8 x 7
Which is 28ft.
Area of semicircle:
The formula to find the area of a semicircle is 1/2[tex]\pi[/tex][tex]r^{2}[/tex]
- We plug in the values given
1/2 x [tex]\pi[/tex] x [tex]4^{2}[/tex]
1/2 x 16[tex]\pi[/tex]
8[tex]\pi[/tex] or 8 x 3.14 = 25.12
In order to get the total area of the whole shape we need to add the areas of those two, which will be 25.12 + 28 = 53.12
