Answer:
1. 10√3
2. -√5
3. 21√3 -9√5
4. 12√7-√11
5. 8√5-3(√5*√4) = 8√5- (3*2)√5= 2√5
6. √5*√4 -√5= 2√5-√5= √5
7. 3√5*√9 +√5*√4 -√49*√5 = 15√5+2√5-7√5= 10√5
8. √6*√4 - √6*√9 + √16*√6= 2√6-3√6+4√6= 3√6

Computers depreciate rapidly. If a new computer that costs $1200 loses 40% of its value every year, what is its worth 5 years from now?
Answer:
$96
Step-by-step explanation:
[tex]f(x)= a(1-r)^x[/tex]
a= initial amount
x= time in years
r= decay rate
[tex]f(x)= 1,200(1-0.4)^5[/tex] ≈
[tex]f(x)= 96[/tex]
A quantity with an initial value of 650 grows exponentially at a rate of 20% every week. What is the value of the quantity after 70 days, to the nearest hundredth?
Answer:
4024.62
Step-by-step explanation:
the value in 70 days can be determined using his formula
FV = P (1 + r)^n
FV = Future value
P = Present value = 650
R = growth rate = 20%
N = number of weeks = 70 / 7 = 10 weeks
650 x (1.2)^10 = 4024.62
Answer:
The Answer is 4024.62

Hint: Lateral Area of a Cone = tre
Where e = slant height
Answer:
Step-by-step explanation:
Answer:
200π cm^2
Step-by-step explanation:
Sb = 8^2 π = 64π cm^2
a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm
Sl = 8x17xπ = 136 π cm^2
SA = 136π + 64π =200π cm^2

Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change
Answer:
The price per cheese stick was increased by 150%.
The amount of cheese sticks per $1.00 has decreased by 60%.
Step-by-step explanation:
The price per cheese stick was $0.10
1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10The current price per cheese stick is $0.25
1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25That means the price per cheese stick was raised by 150%.
That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.

If necessary, round your answer to the nearest whole number.
Answer:
6216
Step-by-step explanation:
This problem deals with exponential growth.
Final value: F
Present (initial) value: P
Rate of growth: r
Time in years = t
[tex] F = P(1 + r)^t [/tex]
[tex] F = 2900(1 + 0.1)^8 [/tex]
[tex] F = 6216 [/tex]
Answer: 6216

4600 X 1.04 to the power of 7?????
Answer:
6053.28618448
no is the power of 6
Answer:
4784 to the power of 7
Step-by-step explanation:
i'm not sure if i interpreted what you wrote correctly, but if its ((4600*1.04)to the power of 7), then my answer would be correct.
if it was 4600*1.04 (where 1.04 would be to the power of 7), then the answer would be about 6053.28618, or 4600*26 to the power of 7/ 25 to the power of 7

8x - 5y =-18
2x + 5y = 58
Answer:
(4,10)
Step-by-step explanation:
8x - 5y = -18
+ 2x + 5y = 58
10x = 40
Dive both sides by 10.
x = 4
2x + 5y = 58
2(4) + 5y = 58
8 + 5y = 58
5y = 50
y = 10
The function f(x) = x2+ 4 is defined over the interval [-2, 2]. If the interval is divided into n equal parts, what is the height of the right endpoint of the k^th rectangle?
Answer:
Following are the responses to the give question:
Step-by-step explanation:
The [tex]f(x) = x^2 + 4[/tex] model is developed in the interval [tex](-2, 2)[/tex] total equal in a between such a range[tex]= 5[/tex].
Its right endpoint of every rectangle is separated onto n equal parts by the height [tex]= \frac{5}{n}.[/tex]
Height of endpoint [tex]= \frac{5}{n}[/tex] of the k rectangles therefore, the height of the kth rectangle = First rectangle height + K rectangle height
[tex]= -2 +k \times \frac{5}{n}\\\\[/tex]
