Answer 2

Answer:

Answers:

24 mm², 26.5 mm

Step-by-step explanation:

Area of the triangle:

$A=(b*h)/(2)\n\nA=(12*4)/(2)\n\n A=(48)/(2)\n\n \boxed{A=24}$

Perimeter of the triangle:

$P=a+b+c \text{ (The side measurements of the triangle.)}\n\nP=6+12+8.5\n\n\boxed{P=26.5}$

Select the algebraic definition for the piecewise function graph.A. 2
B. 4
C. -3 is equal to x <-1
D. -1 is equal to x <1
E. 0
F. 1 is equal to x<3
G. -2 is equal to x<5
H. -3 is equal to x<3
I. 3

Answers

The piece-wise function is defined by:

$f(x) = 1, -3 \leq x < -1$

$f(x) = 2, -1 \leq x < 1$

$f(x) = 3, 1 \leq x < 3$

A piece-wise function is a function that has different definitions, based on the input.

In this graph:

When x is between -3(inclusive, closed circle) and -1(exclusive, open circle), the value is 1, thus, the first definition is:

$f(x) = 1, -3 \leq x < -1$

When x is between -1(inclusive) and 1(exclusive), the value is 2, thus, the second definition is:

$f(x) = 2, -1 \leq x < 1$

When x is between 1(inclusive) and 3(exclusive), the value is 3, thus, the third definition is:

$f(x) = 3, 1 \leq x < 3$

Final answer:

A piecewise function is defined by multiple sub-functions, each applying to a certain interval of the main function's domain. An example might be ' -3 is equal to x <-1', representing a portion of the function where any x-value less than -1 outputs -3.

Explanation:

Without the piecewise function graph, it's difficult to identify the correct algebraic definition. However, a piecewise function is a function which is defined by multiple sub functions. Each sub function applies to a certain interval of the main function's domain, which is why we see conditions like 'x < -1' following the function.

For instance, if we look at option C ' -3 is equal to x <-1', it suggests there is a piece of the function where any x-value less than -1 will output -3. It is important to note that these piecewise functions are visualized on a graph, often appearing as lines or curves that start or stop at certain points.

What is the percentage of 199.50 out of 286?

Answers

286 = 100 %
199.5 = x

In order to find x we need to cross multiply 286*x=199.5*100
286x=19950 / 286
x=69.8 (%)

Solve for t(advanced rational equations)

Answers

t² -7 + 12t⁻² = 0

Multiply each side by t² :

t⁴ -7t² + 12 = 0

This is a quadratic equation in the variable ' t² '.
For just a moment, to avoid confusion, let U = t².
Then the equation is

U² - 7U + 12 = 0
whence
(U - 4) (U - 3) = 0
and
U = 4 and U = 3 .

Now we can go back to ' t² ' in place of U :

t² = 4
t = +2 and t = -2

t² = 3
t = +√3 and t = -√3

$t^2-7+12t^(-2)=0\n t^4-7t^2+12=0\n t^4-3t^2-4t^2+12=0\n t^2(t^2-3)-4(t^2-3)=0\n (t^2-4)(t^2-3)=0\n (t-2)(t+2)(t^2-3)=0\n t=2 \vee t=-2 \vee t=-√(3)\vee t=\sqrt3$
