A 37-foot ladder is leaning against a building. The angle between the ladder and the top of the building is 21. How far up the building does the ladder reach? Round to the nearest tenth.
Answer:
34.5 feets
Step-by-step explanation:
Length of ladder = 37 feet
Angle between ladder and top of building = 21°
Since ladder makes a right angle with the foot of the wall;
Angle the ladder makes with the ground :
(90° + 21° + θ) = 180°
111° + θ = 180°
θ = 180° - 111°
θ = 69°
To obtain the height, x of the building reached by the ladder ;
Using Pythagoras :
Sinθ = opposite / hypotenus
Sin 69° = x / 37
x = 37 * sin 69°
x = 37 * 0.9335804
x = 34.542475
x = 34.54 feets
Hence, the height up the building reached by the ladder is 34.5 feets

Use a vertical format to subtract the polynomials.
3x2 - 2x + 2
- (7x2 + 2x - 3)
Answer:
Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]
Step-by-step explanation:
We need to u se a vertical format to subtract the polynomials.
The polynomials given are:
[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)[/tex]
Now, solving
For, subtraction, the sign of the terms [tex]7x^2 + 2x - 3[/tex] will be changed. - will convert to + because (-)(-) = + and positive sign will be converted to negative (-)(+) = -
The sign with the resulting term will be the sign of term that has greater coefficient. For example if we are subtracting 3x^2 and (-7x^2), the result will be -4x^2 because 7 has negative sign. (term has greater coefficient)
[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)\\\\:\:\:\:\:\:\:-\:\:\:\:-\:\:\:\:\:+\\-----------\\-4x^2-4x+5[/tex]
So, Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]

Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

A pair of fire towers uses technology to search for forest fires. Let the center of the forest be the origin on a coordinate grid. The first fire tower is located 5 km east and 8 km south of the center, and the second fire tower is located 7 km west and 4 km north of the center. The technology at the first tower can locate fires within a radius of 10 km and the second tower within a radius of 9 km. The system of inequalities represents this scenario.
StartLayout Enlarged left-brace first row (x minus 5) squared + (y + 8) squared less-than-or-equal-to 100 second row (x + 7) squared + (y minus 4) squared less-than-or-equal-to 81 EndLayout
At which location, from the origin, would a fire be detected by both towers?

(Repost) The points (2, 1), (5, –2), and (–2, –3) describe the vertices of a triangle. Is the triangle a right triangle? Hint: perpendicular.
Answer: It's a right triangle
Answer: It is a right triangle.
the attachment shows the graphed triangle.
Step-by-step explanation: The slope of the line between coordinates (-2,-3) and (2,1) is +1 rise/run is 4/4
The slope of the line between points (2,1) and (5,-2) is -1 rise/run -3/3
These slopes are perpendicular to each other, so they form the right angle of this triangle.
Gilbert is -17 meters under sea level every second(s) he gains 0.5 meters after how many seconds is he at sea level?
Answer:
He is at sea level after 34 seconds
Step-by-step explanation:
The height at sea level is given as 0 meters
So the change in height would be;
0- (-17) = 17 meters
There is a gain of 0.5 meters in 1 second
So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds
M is the midpoint solve for x
Answer:
x = 3
Step-by-step explanation:
5x + 9 = 24
5x = 24 - 9
5x = 15
x = 3
Check:
5(3) + 9 = 24
SM = 24, MT = 24 ✔️
Answer:
Step-by-step explanation:
If M is the midpoint between points S and T, then both sides; SM and ST are equal. This means that 5x + 9 has to equal 24.
5x + 9= 24
5x +9 - 9= 24 - 9
5x= 15
5x / 5 = 15 / 5
x = 3
ANSWER: x = 3

chicken tenders or chicken nuggets
Answer:
i dont know which one to choose but chicken tenders
Answer:
Chicken tenders.
Step-by-step explanation:
Chicken nuggets are the gross consumption of organs including lungs and others mushed together and fried. In return kids run to it because (most) kids only eat gross stuff. This made the marketing campaign SKY ROCKET with kids everywhere trying to get a bite. FORCING their poor parents to get them that disgusting mush. And then dip it in ketchup. Which is NOT a fruit or veggie. (As the school system thinks they are a veggie.)
While chicken tenders are chopped off the chicken meat then rolled in bread crumbs. And then deep fried to make a crispy exterior with a delicious tender interior. Without getting mushed together with other things.
Also you never know what they put in that chicken nugget since its mushed together ♀️.
