nevsk [136]3 years ago
6 0

Answer:

−3+(−2)(5)+7

=−6

Step-by-step explanation:

Multiply and divide left to right (-2) (5) : 10

Apply rule -a x b = a x b

(-2)(5)= -2 x 5 = -10

= -3  - 10 +7

Add and subtract left to right

-3-10+7

-3 - 10 = 13

= -13 + 7

-13 + 7 = -6

= -6

Hope I helped

15. In the drawing, find the perimeter of triangle BIS.<br>​
Nesterboy [21]

Answer:

29.86 units

Step-by-step explanation:

In the triangle BIS, IT is the bisector of angle BIS,

BI \cong ST.... (given) \\

Let BI = ST = x... (1)

By angle bisector property of a triangle, we have:

\frac{BI}{IS} = \frac{BT}{ST}.... (2)\\\\\frac{x}{12} = \frac{4}{x}\\\\x\times x = 12\times 4\\\\x^2 = 48\\\\x=\sqrt{48}\\\\x = 6.92820323\\\\x = 6.93\\

Therefore,

BI = ST =6.93

Perimeter of triangle BIS

= BI + IS + ST + BT

= 6.93 + 12 + 6.93 + 4

= 29.86 units

*I NEED THIS ASAP*
BigorU [14]

Answer:

5 terms

to the fourth degree

leading coeff of 1

3 turning points

end behavior (when x -> inf, y -> inf. When x -> - inf, y -> -inf)

x intercepts are (0,-4) (0,-2) (0,1) (0,3)

Relative min: (-3.193, -25) (2.193, 25)

Relative max: (-0.5, 27.563)

Step-by-step explanation:

The terms can be counted, seperated by the + and - in the equation given.

The highest exponent is your degree.

The number before the highest term is your leading coeff, if there is no number it is 1.

The turning points are where the graph goes from falling to increasing or vice versa.

End behaviour you have to look at what why does when x goes to -inf and inf.

X int are the points at which the graph crosses the x-axis.

The relative min and max are findable if you plug in the graph on desmos or a graphing calculator.
