you need to subtract 60 from 148 so that it takes the 60 dollars away and is left with what he had before he deposited
Given the exponential function A(x)= P (1+r)^x, what value for r will make the function a decay function
Answer:
negative value for r
Step-by-step explanation:
Given data
Given the exponential function A(x)= P (1+r)^x
A negative value for r will make the function a decay
Hence the decay function will look like
A(x)= P (1-r)^x

Find the volume of the pyramid.
Answer:
118.4
Step-by-step explanation:
So, lets go over what we know:
This is a pyramid.
The height is 8.
The width is 12.
The length is 3.7
We need to find the volume.
The formula for volume of a pyramid is: [tex]\frac{l*w*h}{3}[/tex]
Lets plug our values into this formula and solve:
[tex]\frac{3.7*12*8}{3}[/tex]
Multiplying the numbers on top:
12*8 = 96
96*3.7=355.2
Now lets divide this by 3:
[tex]\frac{355.2}{3}[/tex]
= 118.4
So this is your volume!
Hope this helps! :D
What is the discriminant of Y=9x^2-3x-2???????
Answer:
Discriminant= b²-4ac
a = 9 b = -3 and c = -2
Discriminant = (-3)² - 4(9)(-2)
= 9+72
Discriminant = 81
Ans = 81
I will give brainiest
Answer:
A is equal to 20.
Step-by-step explanation:
To find the missing side we have to square both 21 and 29.
Because 21 x 21 = 441, and 29 x 29 = 841, all we have to do is subtract 841 from 441 and we have 400.
Now we have to find the square root of 400, since 20 x 20 = 400, that means 20 is our answer.
0.055 as a common fraction
Answer:
[tex]\frac{55}{1000}[/tex]
Step-by-step explanation:
The value 0.055 is equal to 55.0 moved 3 decimal places to the left. For each decimal placed moved, divided by 10. Therefore, 0.005 as a common fraction is:
[tex]\frac{55}{10\cdot 10\cdot 10}=\boxed{\frac{55}{1000}}[/tex]
Answer:
55/1000 or 11/200
Step-by-step explanation:
0.055 as a fraction is 55/1000.
This is because for every number there is to the right of a decimal, add an extra '0' to next to the 1 in the denominator.
If 0.055 were 0.05, for example, it would be 5/100.
If 0.055 were 0.0555, it would be 555/10000.
I'm sure you understand now.
Therefore, 0.055 as a common fraction is 55/1000.
55/1000 simplified: 11/200.
Answer the statistical measures and create a box and whiskers plot for the following set of data.
1, 1, 6, 10, 12, 13, 13, 14, 16, 19
Min:
Q1:
Med:
Q3:
Max:
Answer:
min 1
Q1 = 6
med = 12.5
Q3 = 14
Max = 19
Step-by-step explanation:
Min simply refers to the smallest value and that is 1
Q1 is the first quartile and the formula is;
Q1 = (n+ 1)/4
where n is the number of terms which is 10
Q1 = (10 + 1)/4 = 2.75
This is approximately 3 and the 3rd term is 6
med is the median value and that is 12 + 13 = 25/2 = 12.5
Q3 is the third quartile
Q3 = 3(n+ 1)/4 = 8.25 and that is the 8th term which is 14
Max is simply the highest in value and that is 19

a farmer uses 1/3 of his land to plant cassava 3/5 of the remaining land to plant Maize and the rest vegetables if vegetables cover an acre of 10 and area of 10 acres what is the total area of the framers land
Answer:
37.5 acres.
Step-by-step explanation:
Fraction of his land where vegetables are grown
= 1 - 1/3 - 2/3 *3/5
(after taking away 1/3 we get 2/3 and the farmer uses 3/5 of this 2/3 to grow Maize.
= 1 - 1/3 - 6/15 LCD of 3 and 15= 15 so we write:
= 1 - 5/15 - 6/15
= 1 - (5+6)/16
= 1 - 11/15
= 4/15.
4 /15 is equivalent to 10 acres
so total area (= 1) = 10 / 4/15 Invert the 4/15 and multiply:
= 10 * 15/4
= 150/4
= 37.5 acres.
Does the point ( 4 , 47) lie on the line y = 10 x – 3 ?
Show your working .
Answer
Step-by-step explanation:
To find out if a point (x, y) is on the graph of a line, we plug in the values and see if we get a true statement, such as 10 = 10. If we get something different, like 6 = 4, we know that the point is not on the line because it does not satisfy the equation. In the given choices, when we plug in (1, 10) we get 10 = 7 + 2, which is false, making this is the desired answer.
(4, 47) gives 47 = 10(4) - 3 = 37
47=37 is a false statement
What is the definition of a constant term?
Answer: A fixed value.
Step-by-step explanation: In Algebra, a constant is a number is by itself, or sometimes a letter such as a, b or c to stand for a fixed number.
Example: in "x + 5 = 9", 5 and 9 are constants.

The debate team bought 20 matching T-shirts to split among its members. Each member of the team will get t T-shirts. Write an expression that shows how many people are on the debate team.
Answer:
20/t members are on the team
Step-by-step explanation:
From the question, we want to get the number of people on the team
20 T-shirts were bought
each of the team members got t T-shirts
To know the number of people on the team, we have to divide the number of shirts bought by the number of shirts gotten by each team member
We simply have this as 20/t
11.1 m
3.5 m
4 m
4 m
4 m
Answer:
Surface area?
4 x 3.5 x 1/2 (basically just dividing by 2) = 7
11.1 x 4 x 1/2(basically just dividing by 2) = 22.2, 22.2 x 3(three triangles on the sides) = 66.6
Now let's add all the given areas:
7 + 66.6 = 73.6 m^2 is your answer.

O A 2x2 + 1
o B. x2 + 1
o C. 4x2 + 1
OD. 2x2 + x + 1
Answer:
Answer B.
x² + 1
Step-by-step explanation:
x=1
Input x= 1 into x²+1 to get y
(1)²+1 = 2
when x=2
(2)²+1 = 5
when x = 3
(3)² + 1 = 10.
when x=4
(4)² + 1 = 17
Hence Option B

In function graphing, if there is no amplitude change (mainly looking for tangent), what do you write? 1?
Answer:
The period of the tangent function is π because the graph repeats itself on intervals of kπ where k is a constant. If we graph the tangent function on −π2 to π2 , we can see the behavior of the graph on one complete cycle.
The tangent function does not have an amplitude because it has no maximum or minimum value. The period of a tangent function, y=atan(bx) , is the distance between any two consecutive vertical asymptotes..
so its not 1 but 2.
hope its right.
This graph is an example of
A. a linear function
B. a nonlinear function
C. neither a linear nor nonlinear function - it is not a
function at all
The radius of a circular stage is 15 feet. Katie wants to lay down tile to cover the stage. If Katie pays $12.50 per square foot of tile, how much would it cost to tile the entire stage floor? Round to the nearest whole dollar.
Answer:
$8835.75
Step-by-step explanation:
The equation to use for this is for the area of a circle which is:
π r^2
So by plugging in 15 feet:
π 15^2,
π 225,
~706.86 ft^2.
Next, multiply this by the $12.50 per square foot.
706.86 * 12.50 = $8835.75
All done!

A rectangle has a a perimeter of 68 ft. The length and width are scaled by a factor 1.5.
The perimeter of the resulting rectangle is ___ ft.
Answer and Step-by-step explanation:
Here is the equation for finding the sides (just to show):
68 = (2L + 2W)
We multiply L and W by 2 because there are two of the lengths and 2 of the widths.
Now, we add the scale factor to the outside, but on both sides of the equation.
68 × 1.5 = 1.5(2L + 2W)
Multiply 68 by 1.5.
102 = 1.5(2L + 2W)
The answer is 102.
The perimeter of the resulting rectangle is 102 ft.
