If f(x)=x-6 and g(x)=x1/2(x+3), find g(x) times f(x)
Elden [556K]
To solve this problem you must apply the proccedure shown below:
 1. You have the following functions given in the problem above:
 f(x)=x-6 &#10; and g(x)=x1/2(x+3)=x(x+3)/2<span>
 2. You have that g(x) times f(x) can be written as g(x)*f(x). Therefore, you must multiply f(x) * g(x), as following:
 </span>g(x)*f(x)=(x-6)*x(x+3)/2<span>
 3. Applying the distributive property, you have:
</span> g(x)*f(x)=( x^{3} + 3x^2 - 6x^{2} -18x)/2
 g(x)*f(x)=(x^{3} - 3x^{2} -18x)/2
 The answer is:  g(x)*f(x)=(x^{3} - 3x^{2} -18x)/2

Each person at a picnic chose atleast one piece of a fruit one third of the people chose an apple three -quaters of the people c
Natali5045456 [20]

Answer:

-1/12x

Step-by-step explanation:

Let total people at the picnic=x

People who chose apple= 1/3x

People who chose orange= 3/4x

People who chose each of the fruit= People who chose apple + People who chose orange

=1/3x + 3/4x

= 4x+9x / 12

=13/12x

People who chose each of the fruit= 13/12x

what fraction of the people chose both of them?

Fraction of the people who chose both fruits= Total people at the picnic - People who chose each of the fruit

=x - 13/12x

=12x- 13x /12

= -1/12 x

chris runs 2.3 miles every day of the week, except sunday. on sunday he only runs 2 miles. how many miles will he run in 2 weeks
Ludmilka [50]

Answer:

He will run 31.6 miles in two weeks.

Step-by-step explanation:

6 days a week = 2.3 miles

6 days · 2 weeks = 12 days total running 2.3 miles

1 day a week = 2 miles

1 day · 2 weeks = 2 days total running 2 miles

(12 · 2.3) + (2 · 2)

27.6 + 4

31.6 miles

Solve y'' + 10y' + 25y = 0, y(0) = -2, y'(0) = 11 y(t) = Preview
svetlana [45]

Answer:  The required solution is

y=(-2+t)e^{-5t}.

Step-by-step explanation:   We are given to solve the following differential equation :

y^{\prime\prime}+10y^\prime+25y=0,~~~~~~~y(0)=-2,~~y^\prime(0)=11~~~~~~~~~~~~~~~~~~~~~~~~(i)

Let us consider that

y=e^{mt} be an auxiliary solution of equation (i).

Then, we have

y^prime=me^{mt},~~~~~y^{\prime\prime}=m^2e^{mt}.

Substituting these values in equation (i), we get

m^2e^{mt}+10me^{mt}+25e^{mt}=0\\\\\Rightarrow (m^2+10y+25)e^{mt}=0\\\\\Rightarrow m^2+10m+25=0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{since }e^{mt}\neq0]\\\\\Rightarrow m^2+2\times m\times5+5^2=0\\\\\Rightarrow (m+5)^2=0\\\\\Rightarrow m=-5,-5.

So, the general solution of the given equation is

y(t)=(A+Bt)e^{-5t}.

Differentiating with respect to t, we get

y^\prime(t)=-5e^{-5t}(A+Bt)+Be^{-5t}.

According to the given conditions, we have

y(0)=-2\\\\\Rightarrow A=-2

and

y^\prime(0)=11\\\\\Rightarrow -5(A+B\times0)+B=11\\\\\Rightarrow -5A+B=11\\\\\Rightarrow (-5)\times(-2)+B=11\\\\\Rightarrow 10+B=11\\\\\Rightarrow B=11-10\\\\\Rightarrow B=1.

Thus, the required solution is

y(t)=(-2+1\times t)e^{-5t}\\\\\Rightarrow y(t)=(-2+t)e^{-5t}.
