A car is driving away from a crosswalk. The formula d = t2 + 2t expresses the car's distance from the crosswalk in feet, d, in t
alukav5142 [94]

Answer:

8 feet per second.

Step-by-step explanation:

We have been given that a car is driving away from a crosswalk. The formula d=t^2+2t expresses the car's distance from the crosswalk in feet, d, in terms of the number of seconds, t, since the car started moving.

We will use average change formula to solve our given problem.

\text{Average change}=\frac{f(b)-f(a)}{b-a}

\text{Average change}=\frac{d(5)-d(1)}{5-1}

\text{Average change}=\frac{(5)^2+2(5)-((1)^2+2(1))}{4}

\text{Average change}=\frac{25+10-(1+2)}{4}

\text{Average change}=\frac{35-3}{4}\\\\\text{Average change}=\frac{32}{4}\\\\\text{Average change}=8

Therefore, the the car's average speed over the given interval of time would be 8 feet per second.

What is the area of triangle UVW
kogti [31]

This is a polygon with vertices on the lattice.  Let's use Pick's Theorem,

A = (1/2) B + I - 1

where A is the area, B is the number of lattice points on the boundary and I is the number of lattice points in the interior.

In addition to the 3 vertices there are 3 more boundary points on UV and 6 more on WV, none on UV, B=3+3+6=12.   In the interior I count I=9 lattice points.

A = (1/2) 12 + 9 - 1 = 14

Answer: 14

Obviously they just want us to say this is a right triangle, so the legs are altitude and base,

A = (1/2) b h (1/2) |UW| |WV| = (1/2) (4) (7) = 14

That checks.
