19.54 m

Step-by-step explanation:

l(\widehat {AB})  =  \frac{ \theta}{360 \degree}  \times 2 \pi r \\  \\l(\widehat {AB})  =  \frac{140 \degree}{360 \degree}  \times 2 \times 3.14 \times 8 \\  \\ l(\widehat {AB})  =  \frac{7}{18}  \times 2 \times 3.14 \times 8 \\  \\ l(\widehat {AB})  =  \frac{351.68}{18}   \\  \\ l(\widehat {AB})  = 19.5377778 \\  \\ l(\widehat {AB})   \approx 19.54 \: m

Find an equation to the line tangent to y = 5 + |x – 2| at the coordinate (2, 5) pls answer
myrzilka [38]

Answer:

Step-by-step explanation:

Finding an equation of a tangent line to that function requires that we find the derivative of the function at that point. Since this is an absolute value function with its cusp at (2, 5), the function is not differentiable here.

The fifth graders are planning a pizza party. Each fifth grader will eat two slices of pizza with a favorite topping. One-half o
icang [17]
32 students choose a favorite topping for their slices.

Let x be the total number of students.

1/2 of the total students, or 1/2x, choose pepperoni.
1/4 of the total students, or 1/4x, choose extra cheese.
1/8 of the total students, or 1/8x, choose sausage.
4 students choose mushrooms.

We know that together, these equal the total number of students, x:
1/2x+1/4x+1/8x+4=x

We will use 8 as the common denominator:
4/8x+2/8x+1/8x+4=x


Combining like terms:
7/8x+4=x

Subtract 7/8x from both sides:
7/8x+4-7/8x=x-7/8x
4=1x-7/8x
4=1/8x

Divide both sides by 1/8:
4÷(1/8) = 1/8x÷(1/8)
4/1÷(1/8) = x
4/1×8/1 = x
32/1 = x
32 = x
