Answer:
10641.777 feets
Step-by-step explanation:
To obtain the distance to be traveled across the sea, we use trigonometry :
Cosθ = adjacent / hypotenus
Adjacent = 10000
Hypotenus = d
θ = 20°
Cos 20° = 10000 / d
0.9396926 = 10000 / d
d = 10000 / 0.9396926
d = 10641.777
The jet fighter will travel 10641.77 ft far across the sea.
It is given that angle of depression it land at is 20°.
It is required to find how far the sea will travel.
What is the trigonometric ratio?The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
We have an angle of depression = 20°
The height from the sea level = 10,000 ft
From the figure:
[tex]\rm cos20 = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\rm 0.939 = \frac{10000}{d}[/tex]
d = 10641.77 ft
Thus, the jet fighter will travel 10641.77 ft far across the sea.

State the domain for the following relation.{(4, -1), (3, 2), (0, -3), (1, 4)} *
A. {0, 1, 3, 4}
C. {0, 1, 2, 4}
B. {2, 3, 4, 5}
D. {0, 1, 3, 5}
Answer:
A. {0, 1, 3, 4}
Step-by-step explanation:
For a relation with elements (x, y)
The domain is the set of the x-values, that are the input values.
Here we have the relation:
{(4, -1), (3, 2), (0, -3), (1, 4)}
Here we can see that the inputs are:
4, 3, 0, and 1.
Then the domain is:
{4, 3, 0, 1}
Now let's write this in the correct order:
{0, 1, 3, 4}
The domain of the relation is: {0, 1, 3, 4}
Then the correct option is A.

A line that includes the point (-10,-5) has a slope of -8. What is its equation in point-slope form?
Answer:
Step-by-step explanation:
y + 5 = -8(x + 10)
y + 5 = -8x - 80
y = -8x - 85
Answer:
[tex]y + 5 = -8 (x+10)[/tex]
Step-by-step explanation:
The point-slope form of an equation is represented by the formula [tex]y-y_1 = m (x-x_1)[/tex]. Substitute values for the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula to write the equation of the line in point-slope form.
[tex]m[/tex] represents the slope, so substitute -8 in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. Thus, use the x and y values of the point (-10, -5) for the formula. Substitute -10 for [tex]x_1[/tex] and -5 for [tex]y_1[/tex]. This gives the following equation and answer:
[tex]y-(-5) = -8(x-(-10)\\y + 5 = -8 (x+10)[/tex]
Mary has 36 pots. she plants daises in 2/3 of her flower pots
Answer:
24
Step-by-step explanation;
Number of flower pots = 36
Since she plants daisies in 2/3 of her flower pots, the number of flower pots that Mary plant daisies will be:
= 2/3 × 36
= 2 × 12
= 24
She plants daises in 24 flower pots

A 44-inch pendulum swings at an angle of 14°. Find the length of the arc to the nearest hundredth of an inch through which the tip of the pendulum swings.
Answer:
10.75 inches
Step-by-step explanation:
A 44-inch pendulum swings at an angle of 14°. Find the length of the arc to the nearest hundredth of an inch through which the tip of the pendulum swings.
The formula of the length of the arc subtended by pendulum is given as = (x/360)*2πr or (x/180)*πr
Where:-
x = angle subtended by pendulum which is = 14°
r = Length of the pendulum = 44 inch
Lenghth of arc = ?
By putting values
Length of the arc = (14/180 × π × 44
= 10.751228192 inches
Approximately = 10.75 Inches

Y varles directly with X and has a constant rate of change of 6. When the value of Y is 11, then the value of X could be?
greater than 11
less than 2
equal to zero
equal to 6
will give BRAINLIEST if correct
pls no spamming and links WILL be reported
thx >.<
Answer:
less than 2
Step-by-step explanation:
Hello There!
If x varies with y and has a constant rate of change of 6 then we can create an equation to solve for y
y = 6x
Now we want to find x when y = 11
given the y value we plug in 11 to y
11 = 6x
now we solve for x
step 1 divide each side by 6
6x/6
11/6=1.83
we're left with x = 1.83
so we can conclude, when y = 11 x is less than two
extra notes:
because y values directly with x we are using a y = kx equation therefore we don't have to worry about a y intercept because the y intercept would be 0

A publishing house is selling subscriptions to its magazines for 20% off the original price. If a subscription to Newsweek Magazine is on sale for $72, how much does it usually cost?
Answer:
90
Step-by-step explanation:
The magazines are sold at a discount. Discount reduces the price of the good
If the magazines are sold at 20%, the magazine's price would be 80% (100% - 20%) of the original price
let a represent price of the magazine before the discount
This equation represents price of the magazine after the discount
0.8 x a = $72
Divide both sides by 0.8 and find a
a = $90

Biologists discovered an invasive bird species on an island. The function fff models the population size (in hundreds of birds) for this species as a function of time (in months) after being discovered. Plot the point on the graph of fff that corresponds to the number of birds in the population when the biologists discovered it.
The point (4,9) corresponds to the number of birds in the population when the biologists discovered it.
What is a function?The function is a type of relation, or rule, that maps one input to a specific single output.
Biologists discovered an invasive bird species on an island.
The function fff models the population size (in hundreds of birds) for this species as a function of time (in months) after being discovered.
The population drops after 4 months making that the maximum the population of the fish.

6a+4b−66, a, plus, 4, b, minus, 6 when a=1a=1a, equals, 1 and b=3b=3b, equals, 3.
Answer:
The answer is 12.
Step-by-step explanation:
We need to find the value of the given expression 6a+4b−6 when a = 1 and b = 3
Put a = 1 and b = 3 in the above expression.
6a+4b−6 = 6(1) +4(3) -6
= 6+12-6
= 12
So, the value of the given expression is equal to 12.
