Answer:

5 buses and 3 vans were taken.

Step-by-step explanation:

x+y=8

13x+5y=80

----------------

x=8-y

13(8-y)+5y=80

104-13y+5y=80

104-8y=80

8y=104-80

8y=24

y=24/8

y=3

x+3=8

x=8-3=5

x=5, y=3. (5, 3)

5 buses and 3 vans were taken.

Verify that [tan(theta) + cot(theta)]^2 = sec^2(theta) + csc^2(theta)
Wittaler [7]

(tanθ + cotθ)² = sec²θ + csc²θ

<u>Expand left side</u>: tan²θ + 2tanθcotθ + cot²θ

<u>Evaluate middle term</u>: 2tanθcotθ = 2*\frac{sin\theta}{cos\theta}*\frac{cos\theta}{sin\theta} = 2

⇒ tan²θ + 2+ cot²θ

= tan²θ + 1 + 1 + cot²θ

<u>Apply trig identity:</u>  tan²θ + 1 = sec²θ

⇒ sec²θ + 1 + cot²θ

<u>Apply trig identity:</u>  1 + cot²θ = csc²θ

⇒ sec²θ + csc²θ

Left side equals Right side so equation is verified

Slater begins saving for college tuition. He invests $1000 in an account that pays 2.5% simple interest. How many years before h
Brrunno [24]
The formula is Interest = principle times rate times time in years.
                        I=prt        

p=1000
r= 0.025
t=x

To find the amount of interest that is earned in a specific time frame, subtract the final amount of money by the principal. 1500-1000=500.

500 = 1000(0.025)x
500 = 25x   
x= 20 years
