Answer:
$4,224
Step-by-step explanation:
P(principal)=$4,000
R(rate)=1.4%
T(Time): 4 years
A=4,000×(1+(0.014×4))=$4,224
A=$4,224.00
So, Sarah will have $4,224 of interest in 4 years.
speed is 45 miles per hour. 135/45=3, so the answer is 3hours (A)
Answer: 33 pages
Step-by-step explanation:
Let x represent the total number of pages typed by Sharita.
The cost of the first 3 pages = $ 16
Each additional page cost $3
Total amount paid = $106
since the first 3 pages cost $16 , and x represent the total pages , then the remaining pages will be x - 3
Also , since each additional page cost $3 , the cost of the remaining pages will be 3 ( x - 3)
Combining this , we have
16 + 3 ( x -3 ) = 106
16 + 3x - 9 = 106
7 + 3x = 106
3x = 106 - 7
3x = 99
x = 33
therefore ,Sonia's paper was 33 pages long
b
Take a look at everything inside the brackets sqrt(50x^2) = sqrt(5*5*x*x * 2) For ever 2 factors you can bring one out and drop the other one. That means take out 5 * x * sqrt(2). Two is what is left inside the brackets. B must = 2.
c
Do the same thing here. Write all the primes under the square root. Take out 1 for every two under the root sign. sqrt(32x) = sqrt(2*2*2*2*2*x) You can bring out two 2s. There is one left over. Leave it under the root sign. The x is a loner. It stays under the root sign. c = 2 * 2 = 4.
e
Again do the prime factor thing. sqrt(18n) = sqrt(3*3*2*n) = 3*sqrt(2*n)
e = 3
g
sqrt(72*x*x) = sqrt(3 * 3* 2 * 2 * 2 * x * x) = 3 *2 * x* sqrt(2) For every 2 prime factors you can pull out 1 of them outside the square root sign. g = 6
Comment
There are many people on the net and on Brainly that will say that you should know the perfect squares from 1 to 100 (say) so 4 9 16 25 36 49 64 81 100 are the numbers that you should memorize. When they are under the root sign, their roots can be taken out as 2 3 4 5 6 7 8 9 10. For this question I think it is better to use the pairs rule I've given you above. If someone else answers they are likely to do it the way it is written up in this paragraph. It's a free country. You are free to take the answer you like best.
Answer:
the correct awnser is B
Step-by-step explanation:
It will lie in Quadrants I and IV, having center (5, 0) and radius 3. Complete the squares and get the equation in standard form, (x - 5)2 + y2 = 9.
