A 20-ft-long wire is used to support a television antaans. The wire is connected to the
antenna 15 ft above the ground. How far away from the base of the tower will the other
end of the wire be located?
Answer:
The distance of base of wire to the base of tower is 13.27 ft
Step-by-step explanation:
Given as :
The measure of wire connected between base ad antenna top = 20 ft
The wire is connected to the antenna on tower at height h = 15 ft above the ground
Let The distance of base of wire to the base of tower = x ft
Let the angle drawn on ground = Ф
Now, According to question
In figure AOB
Sin angle = [tex]\dfrac{\textrm perpendicular}{\textrm hypotenuse}[/tex]
i.e SinФ = [tex]\dfrac{\textrm AB}{\textrm BO}[/tex]
Or, SinФ = [tex]\dfrac{\textrm h}{\textrm 20}[/tex]
Or, SinФ = [tex]\dfrac{\textrm 15}{\textrm 20}[/tex]
Or, SinФ = [tex]\dfrac{\textrm 3}{\textrm 4}[/tex]
or, Ф = [tex]sin^{-1}(\frac{3}{4})[/tex]
∴ Ф = 48.5°
Now, Again from figure
Tan angle = [tex]\dfrac{\textrm perpendicular}{\textrm base}[/tex]
i.e TanФ = [tex]\dfrac{\textrm AB}{\textrm OA}[/tex]
Or, Tan 48.5° = [tex]\dfrac{\textrm h}{\textrm x}[/tex]
Or, 1.13 = [tex]\dfrac{\textrm 15}{\textrm x}[/tex]
∴ x = [tex]\dfrac{\textrm 15}{\textrm 1.13}[/tex]
i.e x = 13.27 feet
So, The distance of base of wire to the base of tower = x = 13.27 ft
Hence, The distance of base of wire to the base of tower is 13.27 ft Answer
Final answer:
The other end of the wire will be located approximately √175 ft away from the base of the tower.
Explanation:
To find the distance from the base of the tower to the other end of the wire, we can use the Pythagorean theorem. The wire forms the hypotenuse of a right triangle, with one leg being the height of the antenna and the other leg being the distance from the base of the tower. Let's call this distance 'x'.
Using the Pythagorean theorem, we have:
x² + 15² = 20²
Simplifying this equation, we get:
x² = 20² - 15²
x² = 400 - 225
x² = 175
Taking the square root of both sides, we find:
x = √175
So the other end of the wire will be located approximately √175 ft away from the base of the tower.

The correct answer is provided by the third system.
To determine which system of linear inequalities includes the point (2, 1), we need to substitute this point into each inequality and check if the inequalities hold true. Let's evaluate each system step-by-step:
System 1
y < -x + 3y [tex]\leq[/tex] 0.5x + 3Evaluating at (2, 1):
1 < -2 + 3 → 1 < 1 (False)1 ≤ 0.5(2) + 3 → 1 ≤ 4 (True)The point (2, 1) does not satisfy the first inequality, so it is not in the solution set for the first system.
System 2
y < -0.5x + 3y < 0.5xEvaluating at (2, 1):
[tex]1 < -0.5(2) + 3 \rightarrow 1 < 2[/tex] (True)[tex]1 < 0.5(2) →\rightarrow 1 < 1[/tex] (False)The point (2, 1) does not satisfy the second inequality, so it is not in the solution set for this system either.
System 3
y [tex]\leq[/tex] -x + 3y [tex]\leq[/tex] 0.5x + 2Evaluating at (2, 1):
[tex]1 \leq -2 + 3 \rightarrow 1 \leq 1[/tex] (True)[tex]1 \leq 0.5(2) + 2 \rightarrow 1 \leq 3[/tex] (True)The point (2, 1) satisfies both inequalities, so it is in the solution set for the third system.
System 4
y < 0.5xy [tex]\leq[/tex] -0.5x + 2Evaluating at (2, 1):
[tex]1 < 0.5(2) \rightarrow 1 < 1[/tex](False)[tex]1 \leq -0.5(2) + 2 \rightarrow 1 \leq 1[/tex] (True)The point (2, 1) does not satisfy the first inequality, so it is not in the solution set for the fourth system.
The system of linear inequalities that includes the point (2, 1) is the third one: y [tex]\leq[/tex] -x + 3, and y [tex]\leq[/tex] 0.5x + 2.

Whether you write 'a' as a fraction or 'b' as a decimal in the expression ax+bx depends on the context of the problem you're solving. 'a' can be converted to a fraction by expressing the decimal in fractional terms, whereas 'b' can be turned into a decimal by dividing the numerator by the denominator.
Explanation:In the expression ax+bx, where 'a' is a decimal and 'b' is a fraction, deciding whether to write 'a' as a fraction or 'b' as a decimal depends largely on the problem you're solving and what format is most convenient or understandable. To convert 'a' from a decimal to a fraction, you can write the decimal in fractional form. If the denominator is not 100, convert it to a fraction with a denominator of 100, which then allows you to present it as a percentage. On the other hand, to convert 'b' from a fraction to a decimal, you can simply divide the numerator of the fraction by the denominator.
A practical example could be if a=0.5 and b=3/4 in the expression. Here, you can write 'a' as 1/2 (a fraction) and 'b' as 0.75 (a decimal). Therefore, the expression becomes 1/2x + 0.75x.

What is the final amount in a $1500 account earning .75% compound interest for 6 years?
Answers will include a $ sign and round all answers to hundredths place.
Answer:
The final amount in the account after 6 years at compound interest is $1568.78 .
Step-by-step explanation:
Given as :
The principal amount in account = p = $1500
The rate of compound interest = r = 0.75 %
The time period of the loan = t = 6 years
Let The Amount in account after 6 years = $A
From Compound Interest method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]
I.e A = p × [tex](1+\dfrac{\textrm r}{100})^{\textrm t}[/tex]
Or, A = $1500 × [tex](1+\dfrac{\textrm 0.75}{100})^{\textrm 6}[/tex]
Or, A = $1500 × [tex](1.0075)^{6}[/tex]
Or, A = $1500 × 1.04585
Or, A = $1568.775
So, The final amount= A = $1568.78
Hence The final amount in the account after 6 years at compound interest is $1568.78 . Answer

For what value of x does 32x – 93x-4?
оооо
the two solutions are approximately [tex]\( x_1 \approx 2.95 \) and \( x_2 \approx -0.042 \).[/tex]
To find the value of x that satisfies the equation [tex]\( 32x^2 - 93x - 4 = 0 \)[/tex], we can use the quadratic formula:
[tex]\[ x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}} \][/tex]
Where:
- a = 32
- b = -93
- c = -4
Now, let's plug these values into the quadratic formula:
[tex]\[ x = \frac{{-(-93) \pm \sqrt{{(-93)^2 - 4 \cdot 32 \cdot (-4)}}}}{{2 \cdot 32}} \]\[ x = \frac{{93 \pm \sqrt{{8649 + 512}}}}{{64}} \]\[ x = \frac{{93 \pm \sqrt{{9161}}}}{{64}} \]\[ x = \frac{{93 \pm 95.7}}{{64}} \][/tex]
Now, we have two possible solutions:
[tex]\[ x_1 = \frac{{93 + 95.7}}{{64}} \]\[ x_2 = \frac{{93 - 95.7}}{{64}} \]\[ x_1 \approx \frac{{188.7}}{{64}} \]\[ x_2 \approx \frac{{-2.7}}{{64}} \]\[ x_1 \approx 2.95 \]\[ x_2 \approx -0.042 \][/tex]
Therefore, the two solutions are approximately [tex]\( x_1 \approx 2.95 \) and \( x_2 \approx -0.042 \).[/tex]

A $10,000 deposit at the bank will double in value in 9 years. Give a formula for the accumulated amount t years after the investment is made
Answer:
[tex]S = P(1.08)^{t}[/tex]
Step-by-step explanation:
A $10,000 deposit at the bank will double in value in 9 years.
If the interest is r% and it is compounded each year, then we can write from the formula of compound interest that
[tex]20000 = 10000(1 + \frac{r}{100})^{9}[/tex]
⇒ [tex]2 = (1 + \frac{r}{100})^{9}[/tex]
⇒ [tex]1 + \frac{r}{100} = 1.08[/tex]
⇒ r = 8%
Therefore, the formula for the accumulated amount t years after the investment is made will be
[tex]S = P(1 + \frac{8}{100})^{t} = P(1.08)^{t}[/tex]
where, P is the invested principal and S is the accumulated sum. (Answer)

Mr jones is planning to pant grass and place afence in a small area for his dog. The rectagular dimension are 12×15 feet. The grass costs 50 cents per square foot. The small fence costs $8.00 per linear foot.
Answer:
A) The total feet needed for the fence total perimeter is 54 feet
B) The total cost of fence is $432
C) The square feet of grass needed foe the total area is 180 square feet
D) The total cost of the project is $572
Step-by-step explanation:
Given as :
The dimension of rectangular field
Length of rectangular field = L = 12 feet
width of rectangular field = w = 15 feet
The cost of grass per square foot = 50 cents = $0.5 ( ∵ 1 cents = $0.01 )
The cost of small fence = $8 per linear foot
Now, According to question
A ) Let The total feet needed for the fence total perimeter = A feet
∵ Perimeter of rectangular field = 2 × Length + 2 × width
Or, A = 2 × L + 2 × w
Or, A = 2 × 12 feet + 2 × 15 feet
Or, A = 24 feet + 30 feet
∴ A = 54 feet
So, The total feet needed for the fence total perimeter = A = 54 feet
B ) Let The total cost of fence = $B
So, The total cost of fence = The cost of small fence × perimeter of fence
i.e B = $8 × 54 feet
∴ B = $432
So,The total cost of fence = B = $432
C) Let the square feet of grass needed foe the total area = C square feet
∵The Area of rectangular fence = Length × width
Or, The square feet of grass needed foe the total area = Area of rectangular fence = L × w
i.e C = 12 feet × 15 feet
Or, C = 180 feet²
So,The square feet of grass needed foe the total area = C = 180 square feet
D) Let The total cost of grass = $D
∵ The cost of grass per square foot = $0.5
So,Total cost of grass = $0.5 × Area of fence
i.e D = $0.5 × 180 feet²
Or, D = $90
So, The Total cost of grass = D = $90
E) Let the total cost of the project = $E
∵Mr. Jones spend additional $50 for tools
So, The total cost of the project = money spent on tools + total cost of fence + Total cost of grass
i.e E = $50 + B + D
Or, E = $50 + $432 + $90
∴ E = $572
So, The total cost of the project = E = $572
Hence,
A) The total feet needed for the fence total perimeter is 54 feet
B) The total cost of fence is $432
C) The square feet of grass needed foe the total area is 180 square feet
D) The total cost of the project is $572 Answer
