Mathematics
1 answer:
vivado [14]2 years ago
6 0

Answer:

B. 20

Step-by-step explanation:

Cos a = b/c

Cos 53° = b/25

b = 25 × 0,6 = 15

x = √(25² - 15²)

x = √(625 - 225)

x = √400

x = 20

Solve for x: In(x) - In(x+2) = 1
WINSTONCH [101]

The equivalent value of x from the given equation is x = 2e/1-e

<h3>Solving log functions</h3>

Given the log function below expressed as;

lnx - ln(x+2) = 1

Applying the law of logarithm;

ln(x/x+2) = 1

x/x+2 = e^1

x/x+2 = 2.718

x = e(x+2)

x = ex + 2e

x(1-e) = 2e

x = 2e/1-e

Hence the equivalent value of x from the given equation is x = 2e/1-e

Brook drove a total of 180 miles in 3 hours. Diederick drove a total of 160 miles in 4 hours.
ArbitrLikvidat [17]
Actually, DIEDERICK drove faster than BROOK. What you can do to find out the answer, is divide. Brook drove 180 miles in 3 hours, so divide 180 by 3, and you get 60. If you divide 160 by 4, you get 40. So, that means that Diederick drove faster than Brook.

Solve -8x + 4 ≤ 36<br><br>A. x ≥ -4<br><br>B. x ≤ 4<br><br>C. x ≥ 4<br><br>D. x ≤ -4
nexus9112 [7]
- 8x + 4 ≤ 36
Subtract 4 from both sides.
-8x ≤ 32
Divide both sides by -8.        When dividing by a negative number change the
 x ≥  - 4                                   inequality sign.

What is the answer a or b to this question
galina1969 [7]
The answer would be A.

Explanation:

If they enter with one car, that’s a price of $3 for the car alone. Because there’s also a fee for each person who enters, and there is a family of 5 who enters, x is representative of the cost for each person who enters. Therefore, there would be 5 x’s and one 3 that when solved would add up to the total of $45 they spent. That would mean A is correct because the equation would be x + x + x + x + x + 3 = 45.
