If you place a 33-foot ladder against the top of a building and the bottom of the ladder is 26 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answer:
20.3 ft
Step-by-step explanation:
You want to know the height of a building if a 33 ft ladder reaches from the top of the building to a point 26 ft from the bottom of the building.
Right triangleThe geometry can be modeled by a right triangle with hypotenuse 33 ft and one leg of 26 ft. The other leg length (the building height) is found using the Pythagorean theorem.
26² + h² = 33²
h = √(33² -26²) ≈ 20.3 . . . . ft
The building is about 20.3 feet high.

Additional comment
This ladder makes an angle of about 38° with the ground. For ladder safety, an angle around 70° is usually recommended.

The area of the base of a trapezoidal
prism is 95 cm2. The height of the prism is a
cm. What is the volume of the trapezoidal
prism? Describe how you determined your
solution.
Answer:
The surface area of a trapezoidal prism is the amount of area occupied by the surface of a trapezoidal prism. A trapezoidal prism is a three-dimensional solid that is made up of two trapezoids on opposite faces which are joined by four rectangles called the lateral faces. Like all three-dimensional shapes
Step-by-step explanation:
The area occupied by the surface of a trapezoidal prism is known as the surface area of a trapezoidal prism. Since the trapezoidal prism has a flat base, thus we can say that it has a total surface area and a curved surface area. The surface area of any three-dimensional geometrical shape is the sum of the surfaces of that enclosed solid which equals the areas of all of the faces. A trapezoidal prism has two trapezoidal faces four rectangular faces. Thus, the simple formula for calculating the surface area of a trapezoidal prism involves the area of the base, the perimeter of the base, and the slant height of any side of the prism. The surface area of any geometric figure is always measured in square units like cm2, m2, ft, or cubits2.

To find the y-intercept substitute x as 0
[tex]y = 1 \times {0}^{2} + 7 \times 0 - 5[/tex]
[tex]y = 1 \times 0 + 0 - 5[/tex]
[tex]y = 0 + 0 - 5[/tex]
[tex]y = - 5[/tex]
Thus, The y-intercept is -5...~We know that:
The y-intercept of an equation is the constant. Constants are the numerals in the equation.Finding the y-intercept.
In the equation provided, we can see only one constant.

A car traveled 261 miles on 9 gallons of gas. The same car also traveled 145 miles on 5 gallons of gas. If the ordered pairs for this relationship are (gallons,
distance), what is the slope of the line through these two ordered pairs?
Answer:
slope = 29
Step-by-step explanation:
Given that
the ordered pairs for this relationship are (gallons, distance)
it means on coordinate plane
x represents gallons
y represents distance
thus,
two point on plane will be
A car traveled 261 miles on 9 gallons of gas
miles = 261 ---let it be represented by x1
gallons = 9---let it be represented by y1
(x1,y1) = (9,261)
miles = 145 ---let it be represented by x2
gallons = 5---let it be represented by y2
(x2,y2) = (5,145)
slope of two points (x1,y1) and (x2,y2) is given by
slope = m = (y2-y1)/(x2-x1)
thus, slope of the above ordered pair
m = (145-261)/(5-9) = -116/-4 = 29
Thus, slope of the line through these two ordered pairs is 29.

Which equation could be solved using this application of the quadratic formula? PLS HELP
Answer:
d) [tex]2x^2+12x+4=13[/tex]
Step-by-step explanation:
Quadratic formula:
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
The quadratic formula can be used to solve a quadratic equation in the form [tex]ax^2+bx+c=0[/tex]
From inspection of the given quadratic formula:
a = 2b = 12c = -9Therefore, plugging these values into the general form of the quadratic equation:
[tex]2x^2+12x-9=0[/tex]
If we add 13 to both sides we get:
[tex]2x^2+12x+4=13[/tex]
Answer: D
Step-by-step explanation:
The quadratic formula helps you find the roots of a quadratic function, specifically where the function equals zero. In order for an equation to match the use of the quadratic formula shown, the value of 'b' must be +12. It also demands that 'a' must be +2, and 'c' must be -9. Answer D has all these prerequisites.

The speed of an object can be found by dividing the distance traveled by the time it took. It takes Jamal $36$ seconds to skate once around a $500\text{ }\text{m}$ rink. If it takes Tory $40$ seconds to skate the same distance, what is the difference in their speeds?
Answer:
Difference = 13.9 m/s
Step-by-step explanation:
Speed of an object = distance traveled/time taken
Jamal takes 36 seconds to skate 500 m rink. Let his speed is v. So,
[tex]v=\dfrac{500\ m}{36\ s}\\\\=13.89\ m/s[/tex]
Tory takes 40 seconds to skate 500 m rink. Let his speed is v'. So,
[tex]v'=\dfrac{500\ m}{40\ s}\\\\=12.5\ m/s[/tex]
The difference in their speeds,
D = 13.89 - 12.5
= 1.39 m/s
Hence, the difference in their speeds is 13.9 m/s.

Which choice shows a reflection across the x-axis?
A) A
B) B
C) C
D) D
Graph (D) indicates a reflection across the x-axis.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
As we know that reflection across the x-axis is defined as reflecting a point across the y = x, the x-coordinate, and y-coordinate places, and the line y = -x is the coordinates (x, -y).
So reflected across the x-axis: f(x) → -f(x),
⇒ (x,y) → (x , -y)
"A" is a y-axis reflection, "B" and "C" are basically points shifting to a different region of the graph, and "D" is a mirror reflection on the x-axis.
Hence, graph (D) shows a reflection across the x-axis.

Which graph shows the correct graph of y=1/3x+2
This problem can be done by process of elimination.
Notice that in our equation, our slope is positive.
In all these graphs, we have a negative slope.
Slope just describes how steep a line is.
The only graph that has a positive or upward slope is D.
So this is our answer.
Answer:
D
Step-by-step explanation:
The y-intercept (the value of y when x =0) of this graph is y = 1/3(0) +2. So, (0, 2) should be the y-intercept. By looking at the graph of D you can tell that at point x = 0, y = 2. Also, the equation is written in the slope-intercept form (y =mx + b) The slope of this line is 1/3. If you choose any two points from the line and calculate the rise/ run by using the slope formula or by directly counting the units, you will find that it is indeed 1/3.
