Step-by-step explanation:
The radar on a ship picks up two shipwrecks, A and B, 2.5 miles beneath the surface. The distance between the shipwrecks is 0.6 miles. The angle of depression, q, to Shipwreck B depends on the horizontal distance, d, from the ship to Shipwreck A. Write a function for q in terms of d.
Using the principle of trigonometry, the angle of depression, q can be expressed in terms of the horizontal distance, d as [tex]q = tan^{-1} [\frac{(d + 0.6)}{2.5}] [/tex]
Using Pythagoras :
SOHCAHTOAHorizontal distance, d to shipwreck A is added to the distance between shipwrecks A and B to obtain the total horizontal distance
Total horizontal distance = opposite = (d + 0.6) miles Vertical distance = Adjacent = 2.5 MilesTo obtain the angle of depression, q :
Tanθ = opposite / Adjacent[tex] tan q = \frac{opposite}{adjacent}= \frac{total \: horizontal \: distance}{height} [/tex]
[tex] tan q = \frac{d + 0.6}{2.5} [/tex]
Therefore, q can be written in terms of d thus ;
[tex]q = tan^{-1} [\frac{(d + 0.6)}{2.5}] [/tex]Learn more : https://brainly.com/question/17350482

1,531
2,050
1,785
Answer:
3315
Step-by-step explanation:
Given the data:
WEEK ________1 _____2______3______4
no of books __1412___1531 ___2050 ___1785
Number of books sold in weeks 2 and week 4
Books sold in week 2 = 1531
Books sold on week 4 = 1785
(1531 + 1784) = 3315
2x + 7y = 3
x = 1 - 4y
Answer:
(5,-1)
Step-by-step explanation:
Since one of the equations gives x in terms of y , ie x = 1 - 4y
Then this can be substituted directly into the other equation.
→ 2(1 - 4y) + 7y = 3 → 2 - 8y + 7y = 3 → -y = 1 → y = -1
now, substitute y = -1 into x = 1 - 4y , to obtain x
→ x = 1 - 4(-1) = 1 + 4 = 5
Thus solution is (5 , -1 )

3/8 = 15/?
Answer:
40 mark Brainliest please
Step-by-step explanation:
15/40
Let the missing number be x .
Then :-
[tex] \frac{3}{8} = \frac{15}{x} [/tex]
[tex] 3 \times x = 8 \times 15[/tex]
[tex]3x = 120[/tex]
[tex]x = \frac{120}{3} [/tex]
[tex]x = 40[/tex]
The missing number is 40 .
Let us check it by doing cross multiplication :-
[tex]3 \times 40 = 15 \times 8[/tex]
[tex]120 = 120[/tex]
Hence proved the missing number is 40 .
[tex]therefore \: , \frac{3}{8} = \frac{15}{40} [/tex]

Which inequality is true?
Answer:
2 1/3 > 2 1/6
Step-by-step explanation:
2.33 > 2.17 True
How do you know if it is inequality or not w/ fraction?
An equation or an inequality that contains at least one variable is called an open sentence. When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.
To solve an inequality using the following steps:
1) Eliminate fractions by multiplying all terms by the least common denominator of all fractions.
2) Simplify by combining like terms on each side of the inequality.
3) Add or subtract quantities to obtain the unknown on one side and the numbers on the other.

what is 25 2/3 - 15 1/3 =
Answer:
10 1/3
Step-by-step explanation:
Convert mixed numbers into improper fractions (whole number × denominator + numerator)
25 2/3 and 15 1/3
25 × 3 + 2 = 75 + 2 = 77
Put the number over the same denominator
77/3
15 × 3 + 1 = 45 + 1 = 46
Put the number over the same denominator
46/3
77/3 - 46/3
They have common denominators so we can simply subtract the numerator values
77 - 46/3
31/3

Elsa Is taking physical fitness tests in her strength training class. Each day, her results are compared to her resutts from previous days. The first day she completes a test is considered the baseline, and Is represented by 0. For instance, on the first day she did the flexibility test, her result was calculated as 0. On the second day, in comparison to her first day's result, she was able to reach 1 1/16 inches less than the first day, which was recorded as -1 1/16. Then, on the third day, Elsa recorded a result of -5/8.
A. On which day did Elsa reach farther: the second or third day?
B. By how much?
Answer:
A) The second day
B) 9/16 inches
A) Elsa reached farther on the second day because -1/16 > -5/8
B) To calculate this we must first put both fractions above the same denominator. We can then subtract the smaller one from the bigger one:
-1/16 - (-10/16) = 9/16
Elsa reached 9/16 inches farther on the second day then she did on the first.
Hope this helps and have a great day!
Also stay safe! :))))
What is the degree of rotational symmetry for the following figure?
Answer with step-by-step explanation:
For a figure or object that has rotational symmetry, the angle of turning during rotation is called the angle of rotation. Example: when a square is rotated by 90 degrees, it appears the same after rotation. So, the angle of rotation for a square is 90 degrees.

2 step equations: solve the equation below:
m/5+9=11
Answer:
m=10
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
m/5+9-(11)=0
m
Simplify —
5
m
(— + 9) - 11 = 0

Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
9 9 • 5
9 = — = —————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
m + 9 • 5 m + 45
————————— = ——————
5 5
(m + 45)
———————— - 11 = 0
5
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
11 11 • 5
11 = —— = ——————
1 5
Adding up the two equivalent fractions
(m+45) - (11 • 5) m - 10
————————————————— = ——————
5 5
m - 10
—————— = 0

When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
m-10
———— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
m-10 = 0
Solve : m-10 = 0
Add 10 to both sides of the equation :
m = 10
m = 10
