Determina la EPG que adquiere una trapesista de 52 kg de masa cuando sube a un trapecio de 8 metros de altura. Considera g=9.81
Answers
Responder:
4080,96 Julios
Explicación paso a paso:
La energía potencial gravitacional adquirida se puede obtener mediante la relación:
EPG = masa * aceleración por gravedad * altura
Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros
EPG = 52 * 9,81 * 8
EPG = 4080,96 julios
Adam can buy pencils in packages of 12 for $2.19, 40 for $3.99, 50 for $4.75, or 100 for $10. How many pencils are in the package with the lowest unit cost
Answers
Answer:
50 pencils
Step-by-step explanation:
2.19/12 = .18
3.99/40 = .09975
4.75/50 = .095
10/100 = .10
Although with mark-up to the hundredths place, there wouldn't be a logical difference is stores...
Answer:
50 for $4.75
Step-by-step explanation:
First step is to determine the unit cost of each pencil:
price of pack / number of units = cost per pencil
1. $2.19 / 12 = $0.1825
2. $3.99 / 40 = $0.09975
3. $4.75/ 50 = $0.095
4. $10 / 100 = $0.10
The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.
What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?
Answers
Answer:
[-1/2,1/20]
Step-by-step explanation:
Answer:
[-1/2,1/20]
Step-by-step explanation:
In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.
The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.
We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.
The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

Write the equation of a line that is
1
parallel to the line y =1/2
X-3 and passes
through the point (4, 6)?
Answers
Answer:
y = 1/2x + 4
Step-by-step explanation:
If it's parallel, then the slope will remain the same.
To find the y-intercept, you have to plug the coordinates into the equation.
y = 1/2x + b
6 = 1/2 (4) + b
6 = 2 + b
4 = b
y = x - 1
-2x - 3y = -1

What is the value of x in the figure?
Answers
Answer:
x = 27
Step-by-step explanation:
The little square at the bottom of the figure means that that angle is a right angle, or 90°. Knowing that it's a 90° angle and that one section of the adjacent angle is 63°, we just calculate 90-63 to get 27, the value of x.

A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?
Answers
Answer:
189
Step-by-step explanation:
Given data
Initial population=350
Rate = 6%
TIme= 10 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 350(1-0.06)^10
A=350(0.94)^10
A=350*0.5386
A=188.51
Hence the approximate population will be 189
