Answer:

Area = 34.2cm^2

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

a = 8

b = 9

c= 10

Required

Determine the area

This is calculated as:

Area = \sqrt{s(s-a)(s-b)(s-c)

Where

s = \frac{1}{2}(a + b + c)

Substitute values for a, b and c

s = \frac{1}{2}(8 + 9 + 10)

s = \frac{1}{2}(27)

s = 13.5

Substitute values for a, b, c and s in

Area = \sqrt{s(s-a)(s-b)(s-c)

Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)

Area = \sqrt{13.5 * 5.5* 4.5* 3.5

Area = \sqrt{1169.4375

Area = 34.2 -- Approximated

Which function is represented by the graph?
kkurt [141]

Answer:

D. f(x) = -|x+4| +3

The graph is flipped over the x-axis (facing down) so there's a negative sign in front of the function. It's shifted to the left 4 units so it'll be |x+4|. Finally, it's shifted up 3 units so it'll be +3 outside of the absolute bracket.

NOTE: if there's a change to the x value then it's inside the bracket or parenthesis, if there's a change to the y value then it's outside of the bracket or parenthesis

what is the slope intercept form of the equation of the line described by (-4,-5), parallel to y=-2x -5
Eddi Din [679]

Answer:

y = - 2x - 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x - 5 ← is in slope- intercept form

with m = - 2, thus

y = - 2x + c ← is the partial equation of the line

To find c substitute (- 4, - 5) into the partial equation

- 5 = 8 + c ⇒ c = - 5 - 8 = - 13

y = - 2x - 13 ← equation of line
