José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobil

Serga [27]

Answer:

48 miles per hour

Step-by-step explanation:

José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobile. The father overtook José in exactly one hour. This means Jose was riding

5 hours + 1 hour = 6 hours.

Use formula

$D=r\cdot t,$

where

D = distance

r = rate

t = time

In Jose's case,

D = unknown

r = 8 miles per hour

t = 6 hours

Hence,

$D=8\cdot 6=48\ miles$

In Jose's father case,

D = 48 miles

r = unknown

t = 1 hour (father overtook José in exactly one hour)

Hence,

$48=r\cdot 1\\ \\r=48\ miles \ per \ hour$

(X^2+y^2)^2 polynomial identify. Simplify

Alexxx [7]

Answer:

$(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}$

Step-by-step explanation:

(X^2+y^2)^2 polynomial identify. Simplify

i.e

$(x^{2}+ y^{2})^{2} = ?$

Solution:

We have the identity,

$(A+B)^{2}=A^{2}+2AB+B^{2}$

In the Question

$A=x^{2}$

$B=y^{2}$

Substituting in the identity we get

$(x^{2}+ y^{2})^{2} =(x^{2})^{2}+2(x^{2})(y^{2})+(y^{2})^{2}$

Also we have

$(x^{a})^{b} =x^{a\times b}$

$(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}$ Which is the required
