Use the law of cosines to find the value of 2*4*5 cos theta
sweet-ann [11.9K]
We can proceed in solving the problem since all information are given such as 2*4*5costheta.
we have a=4, b=5, and C=theta
let us solve for "c" using Pythagorean
c²=a²+b²
c²=4²+5²
c=6.4
Solving for theta or C
c²=a²+b²-2abcosC
6.4²=4²+5²-2*4*5*cosC
C=90

Angela’s savings account balance was 133.10 after 3 years. What would the balance be after 5 years if the interest rate remains
Novay_Z [31]

In this question , we have to use compound interest formula, which is

A= P(1+r)^t

Here Amount after 3 years = $133.10

Rate of interest = 10%=0.1

TIme =3 years

So we get

133.10= P(1+0.1)^3 \\ 133.10 = P(1.1)^3 \\ 133.10 = 1.331P \\ P = 100

Now we have principal, P = $100,

Rate of interest, r =0.1

Time, t = 5 years

So we will get

A = 100(1+0.1)^5 \\ A = 100(1.1)^5 \\ A = 161.051

So the balance after 5 years will be $161.05 .

For questions 8 – 14, use the following functions:
pogonyaev

we are given

f(x)=5

g(x)=\sqrt{x+2}

(8)

(f+g)(x)=f(x)+g(x)

we can plug it

(f+g)(x)=5+\sqrt{x+2}

(9)

(f-g)(x)=f(x)-g(x)

we can plug it

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

(10)

(f*g)(x)=f(x)*g(x)

we can plug it

(f*g)(x)=5\sqrt{x+2}

(11)

(\frac{f}{g} )(x)=\frac{f(x)}{g(x)}

we can plug it

(\frac{f}{g} )(x)=\frac{5}{\sqrt{x+2}}

(12)

(\frac{g}{f} )(x)=\frac{g(x)}{f(x)}

we can plug it

(\frac{g}{f} )(x)=\frac{\sqrt{x+2}}{5}

(13)

(fog)(x)=f(g(x))

f(x)=5

we can replace g(x)

we get

(fog)(x)=5

(14)

(gof)(x)=g(f(x))

f(x)=5

we can replace f(x)

(gof)(x)=\sqrt{f(x)+2}

we get

(gof)(x)=\sqrt{5+2}

(gof)(x)=\sqrt{7}
