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

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.

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).

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]

B.
The graph has a relative maximum point (-3,4).
C.
The graph has an x-interceptat (1,0).
D.
The graph has the y-axis as a line of symmetry.
E.
The graph has zeros at x = -5 and x = -1.
F.
The graph represents the function f(x) = -x2 - 6x - 5.
Answer:
E
Step-by-step explanation:
The statements that are not true are:
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.
Options, A, B, and E are the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
- The y-intercept can be found by setting x=0, which gives f(0)=-5.
So the y-intercept is (0,-5).
- To find the relative maximum,
We need to find the vertex of the parabola.
The x-coordinate of the vertex is given by -b/2a, where a=-1 and b=-6.
So, x=3 is the x-coordinate of the vertex.
To find the y-coordinate, we plug in x=3 into the function:
f(3) = -(3²) - 6 (3) - 5 = -32.
So the vertex is (3,-32), which is a relative minimum, not a maximum.
- To find the x-intercepts,
We set y =0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
- The y-axis is a line of symmetry for any parabola of form f(x)=ax²,
f(-x) = a (-x)² = ax² = f(x).
- To find the zeros,
We set f(x) = 0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
So the graph has zeros at x = -5 and x = -1, not x = -2 and x = 3.
- The graph represents the function f(x) = -x2 - 6x - 5.
The graph is true.
Thus,
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.

First of all we will find cost of 1 bag of cat food by dividing 15.75 by 3.
Now we will find the amount that Marco has spend for 5 bags of cat food by multiplying 5.25 by 5.
Therefore, Marco has spend $26.25 for purchasing 5 bags of cat food.
Answer:
5.25 per bag
Step-by-step explanation:

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

The surface area of one box is 62 square inches.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Given that, Yolanda makes wooden boxes for a crafts fair.
The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.
We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)
Now, surface area = 2(5×3+3×2+2×5)
= 2(15+6+10)
= 2(31
= 62 square inches.
Therefore, the surface area of one box is 62 square inches.

Solve 7(3 − p) − p ≥ 8p + 5 for p.
Answer:
p ≤ 1
Step-by-step explanation:
Given
7(3 - p) - p ≥ 8p + 5 ← distribute left side and simplify
21 - 7p - p ≥ 8p + 5
21 - 8p ≥ 8p + 5 ( subtract 8p from both sides )
21 - 16p ≥ 5 ( subtract 21 from both sides )
- 16p ≥ - 16
Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity
