At one point during the hike, Noe is at an elevation of 453 feet. After descending at a rate of 50 feet per
minute, she reaches an elevation of 146 feet.
How long does the descent take?
Answers
Answer:
6.14 minutes or 6 minutes & 8.4 seconds
Step-by-step explanation:
Initial elevation: 453 ft
Final elevation: 146 ft
Difference in elevation: 453 ft - 146 ft = 307 ft
speed = 50 ft/min
speed = distance/time
time * speed = distance
time = distance/speed
time = (307 ft)/(50 ft/min)
time = 6.14 minutes = 6 minutes + 0.14 * 60 seconds
time = 6.14 minutes = 6 minutes + 8.4 seconds
1. Sandra is trying to determine the height of a light pole at the corner of the block on
which she lives. The shadow cast by the light pole is 5 feet.
If the angle of elevation from the sidewalk to the top of the light pole is represented
as e, which equation could be used to find the height of the light pole?
Answers
Answer:
h = 5(tane)
Step-by-step explanation:
The diagrammatic representation of the question given is attached below ;
The height of the light pole, h = opposite side
Adjacent side = 5 feets
Angle of elevation = e
Using trigonometry ;
Tan e = opposite / Adjacent
Tan e = h / 5
Making h the subject ;
h = 5(tane)

Sin(Y) = 36/39, if simplified: 12/13, in decimal it would be: 0.92Cos(Y) = 15/39, if simplified: 5/13, in decimal it would be: 0.38Tan(Y) = 36/15, if simplified: 12/5, in decimal it would be: 2.4Angle X:
Sin(X) = 15/39, if simplified: 5/13, in decimal it would be: 0.38Cos(X) = 36/39, if simplified: 12/13, in decimal it would be: 0.92Tan(X) = 15/36, if simplified: 5/12, in decimal it would be: 0.42Hope this helps!
A laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with s = 17.6 milligrams. A confidence interval of 173.8 mg < μ < 196.2 mg is constructed for the true mean cholesterol content of all such eggs. It was assumed that the population has a normal distribution. What confidence level does this interval represent?
Answers
Answer:
The appropriate solution is "95%".
Step-by-step explanation:
The given values are:
Lower bound,
= 173.8
Upper bound,
= 196.2
Mean of cholesterol,
= 138 milligrams
S = 17.6 mg
Now,
The margin of error (E) will be:
= [tex]\frac{Upper \ bound-Lower \ bound}{2}[/tex]
= [tex]\frac{196.2-173.8}{2}[/tex]
= [tex]\frac{22.4}{2}[/tex]
= [tex]11.2[/tex]
As we know,
⇒ [tex]E=t_{\alpha 12}\times \frac{S}{\sqrt{n} }[/tex]
On putting the values, we get
⇒ [tex]11.2=t_{\alpha 12}\times \frac{17.6}{\sqrt{12} }[/tex]
On applying cross-multiplication, we get
⇒ [tex]t_{\alpha 12}=2.2044[/tex]
∴ [tex]\frac{\alpha}{2} =0.025[/tex]
[tex]\alpha = 0.025\times 2[/tex]
[tex]=0.05[/tex]
hence,
The confidence level will be:
⇒ [tex]CI=1-\alpha[/tex]
⇒ [tex]=1-0.05[/tex]
⇒ [tex]=0.95[/tex]
⇒ [tex]=95[/tex]%

c) [tex]\frac{x-2}{x+6}[/tex]
Step-by-step explanation:
When given that function (f) is the following,
[tex]f(x)=\frac{x+2}{x^2+4x-12}[/tex]
The wisest move to first make is to factor the expression, factoring is the process by which one rewrites a quadratic expression as the product of two linear expressions,
[tex]f(x)=\frac{x+12}{(x+6)(x-2)}[/tex]
If is given that function (g) is the following,
[tex]g(x)=\frac{4x^2-16x+16}{4x+48}[/tex]
Then one should also factor the expression,
[tex]g(x)=\frac{4(x-2)^2}{4(x+12)}[/tex]
One is asked to find the following,
[tex]f(x)*g(x)[/tex]
To do this operation, one must multiply the two functions together. It is easiest to do so when the functions are in factored form,
[tex]f(x)*g(x)[/tex]
Substitute,
[tex](\frac{x+12}{(x+6)(x-2)})(\frac{4(x-2)^2}{4(x+12)})[/tex]
Simplify, cross out like terms in the numerator and denominator,
[tex]\frac{x-2}{x+6}[/tex]

What is the solution to this system of equations?
x − 2y = 15
2x + 4y = -18
A. x = 1, y = -6
B. x = 1, y = -7
C. x = 3, y = -6
D. x = 3, y = -7
Answers
Answer:
C. x = 3, y = -6 is the answer.
Step-by-step explanation:
1. Isolate x for x = 2y = 15 -> x = 15 + 2y
2. Substitute x = 15 + 2y -> [2 (15 + 2y) + 4y = -18]
3. Simplify -> [30 + 8y = -18)
4. Isolate y for 30 + 8y = -18 -> y = -6
5. For x = 15 + 2y, substitute y = -6 -> x = 15 + 2(-6)
So, x = 3 and y = -6 are the solutions to this system of equations.

What is the probability of drawing 2 aces (at once) from a standard deck of cards? Leave your answer as a simplified fraction
Answers
Anwner : 4/52
Explanation : The chance of drawing one of the four aces from a standard deck of 52 cards is 4/52; but the chance of drawing a second ace is only 3/51, because after we drew the first ace, there were only three aces among the remaining 51 cards. Thus, the chance of drawing an ace on each of two draws is 4/52 × 3/51, or 1/221.
