F(x)=3 over x+2-x-3 squared what is f(7)
dimaraw [331]

<u>Answer:</u>

f(7)=\frac{-5}{3} or f(7)=-1.67

<u>Step-by-step explanation:</u>

We are given the following function of x and we are to find the value of f ( 7 ):

f ( x ) = \frac { 3 } { x + 2 } - \sqrt { x - 3 }

Substituting the given value (7) in the above function to get:

f(x)=\frac{3}{x+2}-\sqrt{x-3}

f ( 7 )= \ frac{3}{7+2}-\sqrt{7-3}

f(7) = \frac { 3 } { 9 } - \sqrt { 4 }

f(7)=\frac{1}{3}-2

f(7)=\frac{1}{3}-\frac{6}{3}

f(7)=\frac{-5}{3} or f(7)=-1.67

The numerator and the denominator of a fraction are thirteen and fifty, respectively. When a certain number is added to this num
Talja [164]
(13 + x)/(50 - x ) = (2/1)
Cross Multiply
2(50-x) = 1(13 + x)
100 - 2x = 13 + x
add 2x to both sides
100 -2x + 2x = 13 + x + 2x
100 = 13 + 3x
Subtract 13 from both sides
100 - 13 = 13 - 13 + 3x
87 = 3x
divide both sides by 3
29 = x

(13 + 29)/(50-29) = 42/21 = 2 to 1 ratio

Help me find the surface area of the candle
ExtremeBDS [4]

Answer:

Easy!

Step-by-step explanation:

1) To find the surface area of a regular triangular pyramid, we use the formula SA = A + (3/2)bh, where A = the area of the pyramid's base, b = the base of one of the faces, and h = height of one of the faces.

or

2)Multiply the side length of the base by the slant height and divide by two. Then, multiply by 4. This will give you the lateral surface area of the pyramid. Add the base surface area and the lateral surface area.
