Answer:

66.56cm = perimeter

Step-by-step explanation:

First find the easy part (the rectangle)

10+10+17+17=54

subtract the part that is not really there (dashes)

54-8=46

Add the height of the circular part

46+8=54

Find the circumference of a circle with a radius of 8

2(8)(3.14)=50.24

Divide by 4 (the circumference is only 1/4 of the the actual circle in this problem)

50.24/4=12.56

Add all of it together

12.56+54=66.56

]Answer:

$5\frac{5}{16}$

Step-by-step explanation:

Substitute the value of the variable into the equation and simplify.

$2(\frac{1}{4} ^{2} +1-3(\frac{1}{4} ^{2} -3)+3((2*\frac{1}{4}^{2} )-2)$

Solve it out.

Multiply / divide / add / subtract everything out.

Find the vertex and axis of symmetry for f(x)=2x^2-1

vfiekz [6]

<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

Solution:

Given is:

$f(x) = 2x^2 - 1$

We have to find the vertex and axis of symmetry

The general equation is given as:

$f(x) = ax^2 + bx + c$

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

$x = \frac{-b}{2a}$

$x = \frac{0}{2(2)}\\\\x = 0$

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

$f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1$

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)

First change the percent to a decimal 40% = 0.4
then subtract 99 - 0.4 = 98.6
the answer is 98.6
