Answer:
cos(θ) = (5√74)/74
Step-by-step explanation:
The length of the hypotenuse is given by the Pythagorean theorem:
h = √(5² +7²) = √74
The cosine of the angle is the ratio of the adjacent leg to the hypotenuse:
cos(θ) = 5/√74 = (5√74)/74

A study has shown that the daily amount of milk produced by a dairy cow is
normally distributed, with a mean of 6.2 gallons and a standard deviation of
0.7 gallons. On a given day, 95% of the cows will produce an amount of milk
within which of the following ranges?
A. 5.5 gallons to 6.9 gallons
B. 4.8 gallons to 7.6 gallons
O
C. 4.1 gallons to 8.3 gallons
O D. 3.4 gallons to 9.0 gallons
SUBMIT
The range of milk production that 95% of the cows will fall within is option B: 4.8 gallons to 7.6 gallons.
To find the range of daily milk production that 95% of the cows will fall within, we can use the empirical rule, which states that for a normal distribution:
About 68% of the observations fall within one standard deviation of the mean.
About 95% of the observations fall within two standard deviations of the mean.
About 99.7% of the observations fall within three standard deviations of the mean.
Since we are looking for the range of milk production that 95% of the cows will fall within, we need to find the range that is within two standard deviations of the mean. That range is:
Mean ± 2SD
= 6.2 ± 20.7
= 6.2 ± 1.4
= [4.8, 7.6]

What is the value of the expression below?
1 3/4 divided by 1/2 minus (1 1/2)^3
Answer:
1/8
Step-by-step explanation:
Simplify the following:
(1 + 3/4)/(1/2) - (1/2 + 1)^3
Hint: | Write (1 + 3/4)/(1/2) as a single fraction.
Multiply the numerator of (1 + 3/4)/(1/2) by the reciprocal of the denominator. (1 + 3/4)/(1/2) = ((1 + 3/4)×2)/1:
(3/4 + 1) 2 - (1/2 + 1)^3
Hint: | Put the fractions in 1 + 1/2 over a common denominator.
Put 1 + 1/2 over the common denominator 2. 1 + 1/2 = 2/2 + 1/2:
(1 + 3/4) 2 - (2/2 + 1/2)^3
Hint: | Add the fractions over a common denominator to a single fraction.
2/2 + 1/2 = (2 + 1)/2:
(1 + 3/4) 2 - ((2 + 1)/2)^3
Hint: | Evaluate 2 + 1.
2 + 1 = 3:
(1 + 3/4) 2 - (3/2)^3
Hint: | Put the fractions in 1 + 3/4 over a common denominator.
Put 1 + 3/4 over the common denominator 4. 1 + 3/4 = 4/4 + 3/4:
4/4 + 3/4 2 - (3/2)^3
Hint: | Add the fractions over a common denominator to a single fraction.
4/4 + 3/4 = (4 + 3)/4:
(4 + 3)/4×2 - (3/2)^3
Hint: | Evaluate 4 + 3.
4 + 3 = 7:
7/4×2 - (3/2)^3
Hint: | Express 7/4×2 as a single fraction.
7/4×2 = (7×2)/4:
(7×2)/4 - (3/2)^3
Hint: | In (7×2)/4, divide 4 in the denominator by 2 in the numerator.
2/4 = 2/(2×2) = 1/2:
7/2 - (3/2)^3
Hint: | Simplify (3/2)^3 using the rule (p/q)^n = p^n/q^n.
(3/2)^3 = 3^3/2^3:
7/2 - 3^3/2^3
Hint: | In order to evaluate 3^3 express 3^3 as 3×3^2.
3^3 = 3×3^2:
7/2 - (3×3^2)/2^3
Hint: | In order to evaluate 2^3 express 2^3 as 2×2^2.
2^3 = 2×2^2:
7/2 - (3×3^2)/(2×2^2)
Hint: | Evaluate 2^2.
2^2 = 4:
7/2 - (3×3^2)/(2×4)
Hint: | Evaluate 3^2.
3^2 = 9:
7/2 - (3×9)/(2×4)
Hint: | Multiply 2 and 4 together.
2×4 = 8:
7/2 - (3×9)/8
Hint: | Multiply 3 and 9 together.
3×9 = 27:
7/2 - 27/8
Hint: | Put the fractions in 7/2 - 27/8 over a common denominator.
Put 7/2 - 27/8 over the common denominator 8. 7/2 - 27/8 = (4×7)/8 - 27/8:
(4×7)/8 - 27/8
Hint: | Multiply 4 and 7 together.
4×7 = 28:
28/8 - 27/8
Hint: | Subtract the fractions over a common denominator to a single fraction.
28/8 - 27/8 = (28 - 27)/8:
(28 - 27)/8
Hint: | Subtract 27 from 28.
| 2 | 8
- | 2 | 7
| 0 | 1:

A school district currently has 12,000 students. Based on declining enrollment figures, the number of students in the school district is expected to decline by 5% each year. Which of the following functions represents the number of students, S, in the school district after n years?
Answer:
S(n) = 12,000(–0.05)n
Step-by-step explanation:
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]
Original population , P = 12000
Rate of decline, r = 5%
r = 5/100
r = 0.05
The number of years = n
The population of students after n years will be given by the formula:
[tex]S =P(1-r)^n[/tex]
Substitute r = 0.05 and P = 12000 into the formula above
[tex]S=12000(1-0.05)^n\\\\S=12000(0.95)^n[/tex]
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]

Which of the following functions represents an arithmetic sequence?
1. f(n)=3n^2−4
2.f(n)=3n−4
3.f(n)=3^n−4
4.f(n)=3^n−4^n
Answer:
Option (2)
Step-by-step explanation:
Explicit formula of an arithmetic sequence is always in the linear form.
A(n) = a + (n - 1)d
Here A(n) = nth term of the sequence
a = first term
n = number of term
d = common difference
Formula doesn't have the terms with the exponent.
Therefore, from the given options, expression that represents an arithmetic sequence will be,
f(n) = 3n - 4
Option (2) will be the correct option.

solve for x joe thank you Joe Joe mama
The first step that we must take before attempting to solve almost any problem is to determine what the problem statement is asking us to do and what they are giving to us to help finish the problem. Looking at this question we can see that they have requested for us to solve for x and we were provided with a figure.
After understanding what the problem is asking for us to do we can attempt to solve the problem. We can see that there are two angles on a straight line and this is known as supplementary angles. Let us define what supplementary angles are.
Supplementary Angles ⇒ Supplementary Angles are two angles that are formed on a straight line causing them to add up to 180 degrees. Therefore, an expression can be made where the two angles add up to 180 and it can be solved for the unknown.In this case we don't have a missing angle but rather a variable that makes up each of the angles. Using a similar concept we can create an expression with 4x - 6 and 2x and have them combined to equal to 180. After that we can solve for the unknown which in turn would give us x.
Create an expression
[tex]Angle_1 + Angle_2 = 180[/tex][tex](2x) + (4x - 6) = 180[/tex]Combine like terms
[tex]2x + 4x - 6 = 180[/tex][tex](2x + 4x) - 6 = 180[/tex][tex](6x) - 6 = 180[/tex]Add 6 to both sides
[tex](6x) - 6 + 6 = 180 + 6[/tex][tex](6x) = 180 + 6[/tex][tex]6x = 186[/tex]Divide both sides by 6
[tex]\frac{6x}{6} = \frac{186}{6}[/tex][tex]x = \frac{186}{6}[/tex][tex]x = 31[/tex]Therefore, after creating an expression and then simplifying it down all the way to just have the value of x equal to something we were able to determine that the unknown variable of x is equal to 31.
[tex]\huge\text{Hey there!}[/tex]
[tex]\text{Your equation: }\rm{(2x) + (4x - 6) = 180^\circ}\\\large\text{SOLVING for the x-value}\\\rm{2x + 4x - 6 = 180^\circ}\\\large\text{COMBINE the LIKE TERMS}\\\rm{(2x + 4x) + (-6) = 180^\circ}\\\rm{2x + 4x - 6 = 180^\circ}\\\rm{6x - 6 = 180^\circ}\\\large\text{ADD 6 to BOTH SIDES}\\\rm{6x - 6 + 6 = 180 + 6}\\\large\text{SIMPLIFY IT!}\\\rm{6x = 180 + 6}\\\rm{6x = 186}\\\large\text{DIVIDE 6 to BOTH SIDES}\\\rm{\dfrac{6x}{6} = \dfrac{186}{6}}\\\large\text{SIMPLIFY IT!}\\\rm{x = \dfrac{186}{6}}\\\rm{x= 31}[/tex]
