The value of angle C in the triangle is 50°.

<h3>How to calculate the triangle?</h3>

From the information given, the angle A = 60° while B is given as 70° and we are told to calculate the value of C.

It should be noted that the sum of angles on a triangle is 180°. Therefore, the value of C will be:

= 180° - (60° + 70°)

= 180° - 130°

= 50°

An object is launched from a platform.

Bess [88]

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

$h=h(x)=-5x^2+20x+60$

where x is the time (in seconds) passed after the launch.

The time of launch is $x=0$ (0 seconds passed after the launch)

Substitute $x=0$ to find the height:

$h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet$

Calculate the average rate of change for the function f(x) = x4 + 3x3 - 5x2 + 2x - 2, from x = -1 to x = 1

kolezko [41]

In interval <a, b> the average rate of change the function you count from this formula:
$x=\frac{f(b)-f(a)}{b-a} \qquad b>a$
Here you've got a=-1 and b=1:
$f(a)=f(-1)=(-1)^4+3 \cdot (-1)^3 - 5 \cdot (-1)^2 +2 \cdot (-1)-2= \\ = 1-3-5-2-2=-11 \\ \\ f(b)=f(1)=1^4+3 \cdot 1^4 - 5 \cdot 1^2 + 2 \cdot 1 -2=1+3-5+2-2=-1 \\ \\ \hbox{So average rate of change this function is:} \\ \\ x= \frac{-1+11}{1+1}=\frac{10}{2}=5$
