A triangle formed by the sides 3.8cm ,3.7 cm, and 5cm is
Answers
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides.
The triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.
How to find the type of triangle?
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides. Thus,
For a triangle to be right angle triangle,[tex]c^2=a^2+b^2[/tex]
By this law it is observed that,
For a triangle to be acute angle triangle,[tex]c^2<(a^2+b^2)[/tex]
For a triangle to be obtuse angle triangle,[tex]c^2>(a^2+b^2)[/tex]
The sides of the given triangle are 3.8 cm ,3.7 cm, and 5 cm.
Here the longest side is 5 cm. Thus check the type of triangle using above formula. Longest side,
[tex]c^2=5^2\\c^2=25[/tex]
Other two sides,
[tex]a^2+b^2=3.8^2+3.7^2\\a^2+b^2=14.44+13.69\\a^2+b^2=28.13[/tex]
Therefore,
[tex]25<28.13\\[/tex]
Hence the triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.

James wants to buy some CDs that cost $14 each and a DVD that costs $23. He has $65. Write an equation (in the Show your work area) and solve to find how many CDs he can buy. Include "CD" in your answer.
Answers
Answer:
3
Step-by-step explanation:
65-23= 42
42/14= 3
Answer:
14x+23 =65 x=3CDs
Step-by-step explanation:
So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.
To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.

What is the value of this function evaluated at f(-3): f(x) = 2x2+ 5x - 9? F -6 G -42 H 42 J 12
Answers
Answer:
f(-3) = -6
Step-by-step explanation:
f(x) = 2x^2+ 5x - 9
We are to find f(-3)
f(-3) = 2(-3)^2+ 5(-3) - 9
f(-3) = 2(9)-15 - 9
f(-3) = 18 -15 -9
f(-3) = 18-24
f(-3) = -6

The sides of two similar trapezoids are in a ratio of 1:3. The area of the smaller trapezoid is 12 squared inches. Find the area of the larger trapezoid
Answers
Answer:
108 sq in.
Step-by-step explanation:
The ratio of the areas is the square of the ratio of the sides.
Side ratio 1:3
Area ratio 1:9
The side of the larger trapezoid is 3 times the side of the smaller trapezoid.
The area of the larger trapezoid is 9 times the area of the smaller trapezoid.
9 * 12 sq in. = 108 sq in.

Step-by-step explanation:
Step 1: Define Equation
3x - 6 = 9
Step 2: Solve for x
Add 6 to both sides: 3x = 15Divide 3 on both sides: x = 5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(5) - 6 = 9Multiply: 15 - 6 = 9Subtract: 9 = 9Here we see that 9 does indeed equal 9.
∴ x = 5 is the solution to the equation.
