Answer:

<h2>A. R=1098.7ft</h2><h2>B. H=274.7ft</h2>

Step-by-step explanation:

<em>"The question is not complete, here is the complete question</em>

<em> The range R and the maximum height H of a projectile fired at an inclination θ to the horizontal with initial speed v0 are given by the formulas​ below, where g≈32.2 feet per second per second is the acceleration due to gravity. Complete parts A and B.</em>

<em />R=\frac{2v_o^2sin \theta cos \theta}{g}<em />

<em />H=\frac{v_o^2sin^2 \theta}{2g}<em />

<em>A. Find the range R if the projectile is fired at an angle 45° to the horizontal with an initial speed of 190 ft per second</em>

<em>B. Find the maximum height H  if the projectile is fired at angle 45° to the horizontal with an initial speed of 190 ft per second"</em>

<em />

<u>Solution</u>

A. given the expression for Range R

substitute v= 190 ft/sec and ∅=45°

R=\frac{2(190)^2sin(45) cos(45)}{32.2}\\\\R=\frac{72200*0.7*0.7}{32.2}\\\\R=\frac{35378}{32.2} \\\\R=1098.7ft

B. . given the expression for maximum height

substitute v= 190 ft/sec and ∅=45°

H=\frac{v_o^2sin^2 \theta}{2g}\\\\H=\frac{190*190*0.7*0.7}{2*32.2}\\\\H=\frac{17689}{64.4}\\\\H=274.7ft

Answer:

Optimisation Problem

Explanation:

Optimisation Problem is a mathematical economics, computer science problem - which finds the best solution from all feasible solutions (based on constraints & other aspects).

The problem might be in form of maximisation or minimisation. The bus system designing is based on minimizing walking distance. Thus is an optimisation problem.

Find (fºg)(1)<br> f(x) = x² - 1<br> g(x) = √x <br> A.0<br> B.1<br> C.4 √2<br> D. √8
Savatey [412]

Given:

The function are

f(x)=x^2-1

g(x)=\sqrt{x}

To find:

The value of (f\circ g)(1).

Solution:

We have,

f(x)=x^2-1

g(x)=\sqrt{x}

We need to find the value of (f\circ g)(1).

(f\circ g)(1)=f(g(1))            [\because (f\circ g)(x)=f(g(x))]

(f\circ g)(1)=f(\sqrt{1})            [\because g(x)=\sqrt{x}]

(f\circ g)(1)=f(1)      

(f\circ g)(1)=(1)^2-1                  [\because f(x)=x^2-1]

(f\circ g)(1)=1-1      

(f\circ g)(1)=0      

The value of (f\circ g)(1) is 0.

Therefore, the correct option is A.
