Answer:

Yes

Step-by-step explanation:

You're right because Zeros, or roots, are on the x-intercept always. Thus, if you look the porabula has x intercepts at 4 and 6. So x=4 and x=6.

If f(x)=2x^3+5√(x-2) complete the following statement, f(6)=
solong [7]

Answer: 442

Step-by-step explanation:

f(x)=2x^3+5\sqrt{(x-2)}

f(6)

Simply replace all the x's in the equation for 6

f(6)=2(6)^3+5\sqrt{(6-2)}\\ f(6)=2(216)+5\sqrt{4}\\ f(6)=432+5*2\\f(6)=432+10\\f(6)=442

If PQR is a triangle,given that /PQ\=15m, /QR\=17m and /RP\=18m.Find the area of the triangle to the nearest whole number.
nydimaria [60]

Answer:

118.3 m²

Step-by-step explanation:

Step 1. Calculate the <em>semiperimeter</em> (s).

s = (p + q + r)/2

s = (17 + 18+ 15)/2  

s = 50/2

s = 25 m

===============

Step 2. Calculate the <em>area</em> (A).

Use <em>Heron’s formula</em>:

A = \sqrt{s(s-p)(s-q)(s-r)}

A = \sqrt{25(25-17)(25-18)(25-15)}

A = \sqrt{25\times8\times7\times10}

A = \sqrt{14 000}

A = 20\sqrt{35}

A = 118.3 m²
