Find , to the nearest tenth of a foot , the height of the tree represented in the accompanying diagram.
Answers
Answer:
Height of tree = 28.2 ft (Approx)
Step-by-step explanation:
Given:
Angle from ground to top of the tree = 62°
Distance from a point to base of tree = 15 ft
Height of tree = [tex]X[/tex]
Find:
Height of tree = [tex]X[/tex]
Computation:
Using trigonometric application:
[tex]Tan\ 62 = \frac{Height\ of\ tree}{Distance\ from\ a\ point\ to\ base\ of\ tree} \\\\Using\ calculator\ , Tan62 = 1.88\\\\1.88=\frac{Height\ of\ tree}{15} \\\\Height\ of\ tree=28.2ft[/tex]
Height of tree = 28.2 ft (Approx)

Answer: (-4)+4+(-20)- -10=
Answers
Answer:
-10
Step-by-step explanation:
(-4) + 4 + (-20) - (-10) = (-4) + 4 + (-20) + 10
= 0 + (-10)
= (-10)
(-4) + 4 = 0
-20 + 10 = -10. When two numbers have different sign, subtract and the result will have the sign of the bigger number. Here bigger number is 20 and So the result has a negative sign
Answer:
The answer is -10.
Step-by-step explanation:
-4 + 4 = 0
-20 - - 10 = -10
0 + (-10) = -10

Using multiplication, the original number is 7.
What is multiplication?Multiplication is "the process multiplying that the integer is multiplied by number of time".
According to the question,
A number is multiplied by 4. The results is added to 12. The final number is 40. In order to find original number.
4x + 12 = 40
4x = 40 -12
4x = 28
x = 28/4
x = 7.
Hence, using multiplication, the original number is 7.

how would you differentiate this problem using the quotient rule?
Answers
1/3 d/dx [ (2x^2-x^5)/3x^1/2].
Then factor x^2 out of 2x^2-x^5.
Then by using the negative exponent rule you should have
1/3 d/dx [ x^2(2-x^3)x^-1/2 ]
Then multiply x^2 by x ^-1/2 by adding the exponents.
1/3 d/dx [ x^3/2 (2-x^3)]
Then differentiate.
You should get x^1/2 - (3x^7/2)/2.

What is the range of f(x)=(3/4)x-4
Answers
Answer:
Range of the function f(x) is all real numbers greater that -4, i.e., (-4,∞).
Step-by-step explanation:
The given function is f(x) = (3/4)x - 4
The value of (3/4)^x is greater than zero for any value of x. (3/4)^x > 0
Subtract 4 from both the sides. (3/4)^x - 4 > 0 - 4
f(x) > -4
The value of f(x) is greater than -4 for any value of x.
Therefore, the range of the function f(x) is all real numbers greater that -4. (-4,∞).

Answer:
C. 24 degrees
Step-by-step explanation:
All triangle must be 180 degrees in total. So you have to add all the known degrees together to find the missing degree.
120+36=156
Then subtract the sum of the known angles from 180 to find the degree of the unknown angle
180-156=24
Answer: C
Step-by-step explanation:
I'll explain why.
The sum of the angles in a triangle must be equal to 180º. We already know 2 of the 3 angles, therefore, we can make an equation to find x.
The sum of the angles (x+36+120) must be equal to 180 (=180)
x+36+120=180
Combine like terms
x+156=180
Subtract 156 to isolate x
x=180-156
x=24
A cube is a rectangular prism with the same measurement for length, width and height. If a cube is 6
inches tall, what is its volume?
Answers
Answer:
216 inches cubed
Step-by-step explanation:
To find the volume you need length times width times height. Since it is a cube it would be 6 inches * 6 inches * 6 inches which is 216 inches cubed.
Volume of the cube is 216 cubic inch
What is Cube?A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex
What is Rectangular prism?A rectangular prism is a 3D figure with 6 rectangular faces
What is Volume?Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface
Given,
A cube is a rectangular prism with the same measurement for length, width and height
Height of the cube h= 6 inches
Length of the cube l= 6 inches
Width of the cube w= 6 inches
Volume of the cube = l× w × h
Volume of the cube = 6×6×6 =216 cubic inch
Hence the volume of cube is 216 cubic inch

2x + y =6
y = x-3
Solve for x and y
Answers
Answer:
x = 3, y=0
Step-by-step explanation:
2x + y =6
y = x-3
Substitute the second equation into the first
2x +x-3 =6
Combine like terms
3x-3 =6
Add 3 to each side
3x-3+3 = 6+3
3x= 9
Divide each side by 3
3x/3 = 9/3
x =3
Now we need to find y
y = x-3
y = 3-3=0
y=0

My example:
Find the radius of the sphere by substituting 4.5? ft^3 for V in the formula in Step 1 to get: V=4.5? cubic feet.= (4/3)?(r^3)
Multiply each side of the equation by 3 and the equation becomes: 13.5 ? cubic feet =4?(r^3)
Divide both sides of the equation by 4? in Step 4 to solve for the radius of the sphere. To get: (13.5? cubic feet)/(4?) =(4? )(r^3)/ (4?), which then becomes: 3.38 cubic feet= (r^3)
Use the calculator to find the cubic root of 3.38 and subsequently the value of the radius “r” in feet. Find the function key designated for cubic roots, press this key and then enter the value 3.38. You find that the radius is 1.50 ft. You can also use an online calculator for this calculation (see the Resources).
Substitute 1.50 ft. in the formula for SA= 4?(r^2) found in Step 1. To find: SA = 4?(1.50^2) = 4?(1.50X1.50) is equal to 9? square ft.
Substituting the value for pi= ?= 3.14 in the answer 9? square ft., you find that the surface area is 28.26 square ft. To solve these types of problems, you need to know the formulas for both surface area and volume.
