Answers
Answer:
question 1
if you want x to stand alone
you will take the -3 off by crossing it to the other side
NB when a negative number crosses the equal sign it becomes positive
x =10+3= ×=13 is the final answer
Step-by-step explanation:
question 2
you will divide both sides by 2(because we want x to stand alone)
so final answer is ×=4

What is the area of triangle ABC? Round to the nearest whole number
Answers
9514 1404 393
Answer:
C. 837
Step-by-step explanation:
The remaining angle is ...
C = 180° -A -B = 180°-62° -67° = 51°
The law of sines tells us that the length AC is ...
AC/sin(B) = AB/sin(C)
AC = AB·sin(B)/sin(C) = 40·sin(67°)/sin(51°)
Using the area formula given, we now have ...
area = 1/2(AB)(AC)sin(A)
= (1/2)(40)(40·sin(67°)sin(62°)/sin(51°) ≈ 836.7
The area of the triangle is about 837 square units.

A new car costs $23000. The value decreases by 15% each year.(a) Write the exponential model to represent the cars value after t years. (b) To the nearest dollar, how much will the car be worth after 4 years?
Answers
Answer:
(a) 23000(1-15%)^t
(b) about 12006.14375
Step-by-step explanation:
(a) There's a formula for this problem y = A(d)^t where, A is the initial value you are given, d is the growth or decay rate and t is the time period. So, in this case, as the car cost is decreasing it is a decay problem and we can write the formula as such; y = A(1-R)^t
And with the values, we get the exponential model 23000(1-15%)^t
(b) From question (a) we already have the model and the time period given here is 4 years. So putting it in the formula we get,
23000(1-15%)^4
=23000(1-15/100)^4
=23000(0.85)^4
=23000x0.52200625
=12006.14375 (Ans)

What is the height of a triangle of base 10m and an area of 60m²
Answers
A = 0.5*b*h
60 = 0.5*10*h
60 = 5h
5h = 60
h = 60/5
h = 12
Answer: The height is 12 meters.
Answer:
6 m
Step-by-step explanation:
Since the area is 60 m squared and the base is 10 m, the height is 12.
Formula: base x height / 2 = area
= 10 x height / 2= 60 m squared
60 / 10 = 6 x 2 = 12.

For each year t, the number of trees in Forest A is represented by the function A(t) = 72(1.025). In a neighboring forest, the number of trees in Forest B is represented by the function B(t) = 63(1.029).
Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number of trees after 20 years? By how many?
Round your answer to the nearest tree.
Forest A or B will have _________ more trees.
Answers
Answer:
Forest A will have 6 more trees.
Step-by-step explanation:
The number of trees in Forest A is represented by the function:
[tex]A(t)=72(1.025)^t[/tex]
And Forest B is represented by:
[tex]B(t)=63(1.029)^t[/tex]
And we want to determine which forest will have the greater number of trees after 20 years.
So, evaluate both functions for t = 20. For Forest A:
[tex]\displaystyle \begin{aligned} A(20)&=72(1.025)^{20} \\ &=117.9803...\\ &\approx 118 \text{ trees} \end{aligned}[/tex]
And for Forest B:
[tex]\displaystyle \begin{aligned} B(20) &= 63(1.029)^{20} \\ &=111.5958... \\ &\approx 112 \end{aligned}[/tex]
Therefore, after 20 years, Forest A will have 6 more trees.

Use the chain rule:

Thus:
dy/dx sin(x) = cos(x)
dy/dx cos(x) = -sin(x)

What proportion of the students scored at least 23 points on this test, rounded to five decimal places
Answers
This question is incomplete, the complete question is;
The distribution of scores on a recent test closely followed a Normal Distribution with a mean of 22 points and a standard deviation of 2 points. For this question, DO NOT apply the standard deviation rule.
What proportion of the students scored at least 23 points on this test, rounded to five decimal places?
Answer:
proportion of the students that scored at least 23 points on this test is 0.30850
Step-by-step explanation:
Given the data in the question;
mean μ = 22
standard deviation σ = 2
since test closely followed a Normal Distribution
let
Z = x-μ / σ { standard normal random variable ]
Now, proportion of the students that scored at least 23 points on this test.
P( x ≥ 23 ) = P( (x-μ / σ) ≥ ( 23-22 / 2 )
= P( Z ≥ 1/2 )
= P( Z ≥ 0.5 )
= 1 - P( Z < 0.5 )
Now, from z table
{ we have P( Z < 0.5 ) = 0.6915 }
= 1 - P( Z < 0.5 ) = 1 - 0.6915 = 0.30850
P( x ≥ 23 ) = 0.30850
Therefore, proportion of the students that scored at least 23 points on this test is 0.30850
Let the probability of success on a Bernoulli trial be 0.26. a. In five Bernoulli trials, what is the probability that there will be 4 failures
Answers
Answer:
0.3898 = 38.98% probability that there will be 4 failures
Step-by-step explanation:
A sequence of Bernoulli trials forms the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Let the probability of success on a Bernoulli trial be 0.26.
This means that [tex]p = 0.26[/tex]
a. In five Bernoulli trials, what is the probability that there will be 4 failures?
Five trials means that [tex]n = 5[/tex]
4 failures, so 1 success, and we have to find P(X = 1).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{5,1}.(0.26)^{1}.(0.74)^{4} = 0.3898[/tex]
0.3898 = 38.98% probability that there will be 4 failures
the division method of 680624 and 165649
Answers
9514 1404 393
Answer:
680624 = 2^4 · 7 · 59 · 103165649 = 11^2 · 37^2Step-by-step explanation:
Using the division method, you find prime divisors that give integer quotients until the final quotient is a prime. For small divisors, it is beneficial to make use of divisibility rules. For larger ones, you just have to try the list of primes to see what you get.
680624The last two digits are divisible by 4, so the number can be divided by 2 twice (at least). We can keep dividing by 2 as long as the 1s digit is even.
680624/2 = 340312
340312/2 = 170156
170156/2 = 85,078
85078/2 = 42539
The next prime is 3. The divisibility rule for 3 is the sum of digits must be divisible by 3. 4+2+5+3+9 = 23, not divisible by 3.
The next prime is 5. For divisibility by 5, the number must end in 0 or 5. This is not divisible by 5.
The next prime is 7. For divisibility by 7, there are several possible rules you can use. One I find relatively easy to remember is to subtract double the 1s digit from the rest of the number and see if that is divisible by 7. Here, that gives ...
4253 -2(9) = 4235; 423 -2(5) = 413; 41 -2(3) = 35 . . . divisible by 7
Continuing, we have ...
42539/7 = 6077
There are additional divisibility rules for 11 and 13 that can be applied. For divisibility by 11, we can add pairs of digits: 77 +60 = 137, not divisible by 11.
For divisibility by 13, we can add 4 times the last digit to the rest:
4253 +4(9) = 4289; 428 +4(9) = 464; 46 +4(4) = 62 . . . not divisible by 13
__
After this point, it is a matter of trying the primes one by one to see what the number may be divisible by. This "trial and error" will show you ...
6077/59 = 103 . . . 103 is prime, so we're done
The final factorization is ...
680624 = 2^4 · 7 · 59 · 103
__
165649As luck would have it, this is a perfect square, so we can immediately reduce the problem to something a little easier.
√165649 = 407
We can see "immediately" that this is not divisible by 2, 3, 5, or 7. However, 04+07 = 11, so this is divisible by 11.
407/11 = 37 . . . 37 is prime, so we're done
The final factorization is ...
165649 = 11^2 · 37^2

As you can probably tell, it is convenient to have a list of prime numbers available. Here is a list of the first few primes.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59,
61, 67, 71, 73, 79, 83, 89, 97, 101, 103
_____
Additional comment
If you start with the smallest primes, (2, 3, 5}, once you find a prime divisor, you only need to try primes greater than or equal to that one on the quotient. In any event, you only need to try primes up to the square root of the value you're trying to factor. If none of those work, then the number itself is a prime.
In the first problem, once we got to 6077, we would only need to try primes up to √6077 ≈ 77. That is, if 6077 turned out to be not divisible by any prime equal to 73 or less, then 6077 would be the last prime factor. (As we found, 6077 is composite, not prime, so using that number is just to illustrate the point regarding the largest value needed to be tested.)
