Answer:
7.2 feet
Step-by-step explanation:
plug in x = 3 since we are looking for the height after the 3rd bounce
4(0.6)(3)
4(1.8)
7.2
The height after the third bounce is 0.86 feet.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 4 x [tex]0.6^x[/tex] models the ball’s height in feet after each bounce.
Where x is the bounce number.
Now,
Substituting x = 3,
f(x) = 4 x [tex]0.6^x[/tex]
f(x) = 4 x [tex]0.6^3[/tex]
f(x) = 4 x 0.6 x 0.6 x 0.6
f(x) = 0.864
f(x) = 0.86
The height after the third bounce is 0.86 feet.

1.If the part is bigger than the whole, what must be true about the percent 2.If the part is smaller than the whole, what must be true about the percent ?
Answer:
1.greater than 100%
2.less than 100%
Step-by-step explanation:
A whole is represented by the percentage 100%. Therefore, if the part being targeted is bigger than the whole then it would be greater than 100%. While, if the part is smaller than the whole then it would be less than 100%. This is always true in every scenario due to "a whole" being represented as the entirety of the object or data in question, which is why in numerical value it is shown as being 100%

Two high schools are going on a field trip. One rents 8 vans and 9 buses for 228 students. The other rents 4 vans and 5 buses for 124 students. How many people can you fit in a van? How many people can you fit in a bus?
Answer:
No. pp you can fit in a van: 6,
No. pp you can fit in a bus: 20
Step-by-step explanation:
Let v = # of pp in vans, and let b = # of pp in buses:
8v + 9b = 228,
4v + 5b = 124
If we solve this system of equations by substitution, we isolate the first eq. for v and then substitute into the bottom eq:
v = 228-9b/8,
Substitute v = 228-9b/8 into bottom eq:
[4 * 228-9b/8 + 5b = 125]
[228+b/2=124]
[228+b = 248]
[b = 20]
Now substitute 20 to find no. of pp in the vans:
v = 228 - 9(20)/8 = 228 - 180/8 = 48/8 = 6
Your younger sibling runs up to you and excitedly exclaims, "I'm thinking of a number. If I add it to the number 2 ten times, that is, 2 + my number + my number + my number, and so on, then the answer is 2. What is my number?" You almost immediately answer, "zero," but are you sure? Can you find a different number (other than zero) that has the same property? If not, can you justify that your answer is the only correct answer?
Answer:
[tex]x = 0[/tex]
Step-by-step explanation:
Given
Represent the number with x.
So:
[tex]2 + x + x + x + x + x + x + x + x + x + x = 2[/tex]
or
[tex]2 + 10x = 2[/tex]
We want to solve for x
Subtract both sides by 2
[tex]2 - 2 + 10x = 2 - 2[/tex]
[tex]10x = 0[/tex]
Solve for x
[tex]x = \frac{0}{10}[/tex]
[tex]x = 0[/tex]
No other number aside 0, satisfy the property.

Find the value of x.
Answer:
C
Step-by-step explanation:
We're given the adjecent and we're looking for the hypotenuse so we'll have to use cosine ratio.
11 / cos 38 = 13.959.....
x = 14.0
We can also use the tangent ratio to look for the opposite and then use pythagorean to find the hypotenuse.
11(tan 38) = 8.594......
8.594.....² + 11² = 194.859......
Square root of 194.859..... = 13.959.......

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
help quickly
Answer:
£3692
Step-by-step explanation:
A = p(1 + r/n)^nt
Where,
A = future value
P = principal = £2350
r = interest rate = 4.2% = 0.042
n = number of periods = 1(annual)
t = time = 4 years
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Total years = 10
Remaining years = 10 - 4
= 6 years
Remaining 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692

13. $75 to $25
Answer:
-66.67%
Step-by-step explanation:
Here 75 is the old value and 25 is the new value, so this will result into a negative change. Meaning that this is a decreasing change. So the percent of change is -66.67%, and this is a decrease. Hope this is helpful, have a great day :)))

A donut shop made 32 donuts with frosting and 18 donuts without frosting. What is the ratio of the number of donuts with frosting to the number of donuts without frosting?
Answer:
16 to 9
Step-by-step explanation:
Represent donut with frosting with D1 and donut without frosting with D2.
So, we have:
[tex]D_1 = 32[/tex]
[tex]D_2 = 18[/tex]
Required
Find the ratio of D1 to D2
This is calculated as:
[tex]D_1 : D_2[/tex]
Substitute values for D1 and D2
[tex]D_1 : D_2 = 32 : 18[/tex]
Divide by 2
[tex]D_1 : D_2 = 32/2 : 18/2[/tex]
[tex]D_1 : D_2 = 16 : 9[/tex]
The ratio of donuts with frosting to donuts without is 16 to 9
Answer:
16 to 19
