From a hot-air balloon, Daniel measures a 33^{\circ} ∘ angle of depression to a landmark that’s 1579 feet away, measuring horizontally. What’s the balloon’s vertical distance above the ground? Round your answer to the nearest tenth of a foot if necessary.
The balloon’s vertical distance above the ground is 860.0 ft
Right angle triangle:Right angle triangle are triangle that has one of its sides as 90 degrees. The side of the triangle can be found using trigonometric ratios. Therefore,
The horizontal distance from the landmark tot he hot balloon is 1579 feet and it is the hypotenuse side of the triangle formed. Therefore, the vertical height is the opposite sides.
Using trigonometric ratio,
sin 33° = opposite / hypotenuse
sin 33° = x / 1579
cross multiply
x = 1579 × sin 33
x = 1579 × 0.54463903501
x = 859.985036289
x = 860.0 ft

Answer:
Equation 1 matches with number 9.
Equation 2 matches with number 7.
Equation 3 matches with number 1.
Equation 4 matches with number 3.
Equation 5 matches with number 5.
Step-by-step explanation:
Equation 1: −9x > −9
−9x > −9
Divide both sides by −9.
-9x/-9 = -9/-9
Since −9 is negative, the inequality direction is changed.
x < 1
x < 1 matches with the graphed solution of number 9.
So, Equation 1 matches with number 9.
Equation 2: 2x + 6≥ −2
2x + 6≥ −2
Step 1: Subtract 6 from both sides
2x + 6 − 6 ≥ −2 − 6
2x ≥ −8
Step 2: Divide both sides by 2
2x/2 ≥ −8/2
Step 3: Simplify
x ≥ -4
x ≥ -4 matches with the graphed solution of number 7.
So, Equation 2 matches with number 7.
Equation 3: x − 9 < −5
x − 9 < −5
Step 1: Add 9 to both sides.
x − 9 + 9 < −5 + 9
Step 2: Simplify
x < 4
x < 4 matches with the graphed solution of number 1.
So, Equation 3 matches with number 1.
Equation 4: −6x < −12
−6x < −12
Divide both sides by -6
-6x/-6 < -12/-6
Since −6 is negative, the inequality direction is changed
x > 2
x > 2 matches with the graphed solution of number 3.
So, Equation 4 matches with number 3.
Equation 5: -7x + 20 > 55
-7x + 20 > 55
Step 1: Subtract 20 from both sides.
−7x + 20 − 20 > 55 − 20
Step 2: Simplify
−7x > 35
Step 3: Divide both sides by -7.
-7x/-7 > 35/-7
Step 4: Simplify
x < -5
Since −7 is negative, the inequality direction is changed
x < -5 matches with the graphed solution of number 5.
So, Equation 5 matches with number 5.

2x+4y=60 and y=x+3 i need a answer quick
It is asking for the intercept.
y = x + 3 becomes y - x = 3
multiply it by two, so it becomes -2x + 2y = 6. Then add it to the other equation, and solve for y.
2x + 4y = 60
(2x + 4y) + (-2x + 2y) = 60 +6
6y = 66
y = 11
Plug in the known y into the the easiest equation.
11 = x +3
x = 8
Intercept: (8, 11)

For group A, the left end mark is at 1, the left edge of the box is at 3, the line inside the box is at 4, the right edge of the box is at 5, and the right end mark is at 7 point 5. For group B, the left end mark is at 3, the left edge of the box is at 4, the line inside the box is at 5, the right edge of the box is just past 5, and the right end mark is at 7 point 5. Select all the inferences that you can make. Group B has a higher median than Group A. Group B has a higher mean than Group A. Group B has more overall variability than Group A. Group B has a smaller range than Group A. Group A and B have the same maximum value
We can conclude the following about the box plots:
Group A had lower median than group B. Group B has less overall variability because it has a smaller range than group A.What is Median and Range of a Data Set?Median is the middle value which is represented by a vertical line that divides the rectangular box in a box plot.
Median for Group A is smaller than the median of Group B.
Range of a data set is the difference between the maximum value and the minimum value. Range is a measure of variability. The bigger the range, the more the variability and vice versa.
Range of Group A is larger than range of Group B.

A function f gives the number of stray cats in a town t years since the town started
an animal control program. The program includes both sterilizing stray cats and finding homes to adopt
them. An equation representing f is f(t) = 243(3)'.
What is the value of f(t) when t is 0? Explain what this value means in this situation?
Answer:
f(0) = 243 . . . cats at the start
Step-by-step explanation:
The exponential function tells you the number of cats after t years is ...
f(t) = 243(1/3)^t
When t=0, the exponential factor is 1, so the value of the function is the multiplying constant.
f(0) = 243
This means there were 243 stray cats in town when the animal control program started.

Veronica has to multiply 398 x 18. She says she can multiply 400 X 18 and then take
away one group of 18.
Write an expression that shows Veronica's thinking
Answer:
See below. Veronica's thinking is incorrect. I've included what she is thinking, but the correct thinking is more useful, as noted below.
Step-by-step explanation:
398 is 2 less than 400. Veronica needs to remove two groups of 18.I don't know what Veronica is thinking, other than:
(398 x 18) = (400*18 - 18)
She should be thinking:
(398 x 18) = (400 x 18) - (2*18). The "2" is for the two extra groups of 18 that she will have when multiplying 400 x 18, instead of 398 x 18.

The amount Marcia saved in interest by consolidating the two balances will be $105
What will be the amount Marcia will save in interest by consolidating the two balances?It is given that
For Card A = 1,879.58 ; APR 14%; monthly = 43.73
For Card B = 861.00 ; APR 10% ; monthly = 18.29
Now [tex]\rm 5\ Years \times\ 12\ months =60\ months[/tex]
For Card [tex]A=43.73\times60=2623.80[/tex]
For Card [tex]B=18.29\times60=1097.40[/tex]
Now the [tex]\rm Total=2623.80+1097.40=3721.20[/tex]
Since Lowest APR is 10%. monthly rate: 0.83%
So the Total Card balance [tex]1879.58+861=2740.58[/tex]
[tex]A=\dfrac{P\times r(1+r)^n}{(1+r)^n} -1[/tex]
[tex]A=\dfrac{2740.58\times(0.0083(1.0083)^{60}}{1.0083^{60}}-1[/tex]

Q3
Answer:
D. 7.5 inches
Step-by-step explanation:
So, we can find the ratio of the big triangle to the small one by dividing the values of the hypotenuse.
So, 18/6 = 3
Big:small = 3:1
So, using this we can make an equation to find AD.
Let's say ED=x.
AD is basically ED (x) + AE (5).
Since ED is part of the small triangle, and AD is part of the big one, we can use the 3:1 ratio from above.
So, [tex]\frac{x+5}{x}[/tex]=3.
Multiply both sides by x, getting x+5 = 3x.
Subtract the x: -x -x
And you get 5=2x, giving you 2.5 = x.
However, we're not done yet, as 2.5 is the value of ED, but we need AD.
Remember, AD is = ED + AE.
So, AD = 2.5 + 5.
Finally, AD = 7.5
